Important Notice Regarding 9060 Probe Option ‐ FIL‐3
WARNING: The only identifiable standard for flame arresters for general use is British Standard BS
EN 12874:2001. British Standard BS EN 12874:2001 refers to an operating environment up to 150
Degrees Centigrade.
The FIL‐3 device optionally fitted to 9060 Heated Zirconia Probes (the “Probes" or "Probe")
operate in an environment considerably greater than 150 Degrees Centigrade.
Therefore, we know of no Australian, British, European or USA standard applicable to flame
arresters or their testing above 150 degrees Centigrade. Consequently, the FIL‐3 device cannot be
certified as a safety device.
The probe is only on probes during the start up processes of a combustion appliance.
The Teledyne Analytical Instruments Burner Interlock Relay facility, which is a standard part of the
Teledyne Analytical Instruments transmitter, is designed to be wired to the main safety shut‐off
fuel valves in a way that can shutdown the probe heater when the fuel valves are closed.
The risk of ignition of flammable gas mixture at the hot end of the Probe can only be minimized by
correct use, maintenance and operation of the FIL‐3 device. The user of the FIL‐3 device is
responsible for verification and maintenance and correct use and operation of the FIL‐3 device.
THE USER AGREES THAT IT USES THE PROBE AND THE FIL‐3 DEVICE AT ITS SOLE RISK. TELEDYNE
ANALYTICAL INSTRUMENTS TO THE FULL EXTENT PERMITTED BY LAW, GIVES NO WARRANTIES OR
ASSURANCES AND EXCLUDES ALL LIABILITY (INCLUDING LIABILITY FOR NEGLIGENCE) IN RELATION
TO THE PROBE AND THE FIL‐3 DEVICE.
The user must ensure that it correctly follows all instructions in relation to the Probe and FIL‐3
device, correctly understands the specifications of the Probe and FIL‐3 device and ensures that the
Probe and FIL‐3 device are regularly inspected and maintained.
FIL‐3 equipped Probes should be inspected at least once a year for corrosion and more frequently
if there is any reason to suspect that corrosion may have occurred.

1. IMPORTANT NOTICES
This manual is intended as a supplement to the 9060Z Operators Manual. It is intended to be used by
technical personal that are qualified to install, commission, service and calibrate electronic industrial
control equipment.
Please read the safety information below before connecting power to the transmitter.
CAUTION 1
The probe heater is supplied with mains voltage. This supply has electrical shock danger to
maintenance personnel. Always isolate the transmitter before working with the probe. The EARTH
wires (green/yellow) from a heated probe must ALWAYS be connected to earth.
CAUTION 2
Combustion or atmosphere control systems can be dangerous. Burners must be mechanically set up
so that in the case of equipment failure the system cannot generate explosive atmospheres. This
danger is normally avoided with flue gas trim systems by adjustment so that in the case of failure the
appliance will not generate CO in excess of 400 ppm in the flue. The CO level in the flue should be
measured with a separate CO instrument normally an infrared or fuel cell type.
CAUTION 3
The oxygen probe is heated to over 700°C (1300°F) and is a source of ignition. Since raw fuel leaks can
occur during burner shutdown, the transmitter has an interlocking relay that removes power from the
probe heater when the main fuel shut‐off valve power is off. If this configuration does not suit or if it
is possible for raw fuel to come into contact with a hot oxygen probe then the Model 9060Z
transmitter with a heated probe will not be safe in your application. An unheated probe can be
utilized in such applications, however the oxygen readings are valid only above 650°C (1200°F).
CAUTION 4
The reducing oxygen signal from the transmitter and the associated alarm relay can be used as an
explosive warning or trip. This measurement assumes complete combustion. If incomplete
combustion is possible then this signal will read less reducing and should not be used as an alarm or
trip. A true excess combustibles analyzer, normally incorporating a catalyst or thermal conductivity
bridge, would be more appropriate where incomplete combustion is possible. Also read the probe
electrical shock caution in the probe heater interlock caution in chapter 4.7
CAUTION 5
FIL‐3 filter. If the optional FIL‐3 has been fitted to the 9060H probe in this installation, please read the
Important Notice regarding probe option FIL‐3 on the previous page.
CAUTION 6
The heater is supplied from the mains power directly, and the temperature is controlled at 720°C
(1330°F). The outside of the process end of the probe can get to temperatures that are dangerous to
touch. Wear insulating gloves when handling a probe that has been on.

2. INTRODUCTION
2.1 9060Z TRANSMITTER
The Teledyne Analytical Instruments 9060Z oxygen transmitter is designed to measure the oxygen gas
concentration in combustion applications such as power stations and industrial boilers. The
measurement is used to control the air / fuel ration in the burner to maintain efficiency and safe
operation conditions.
The transmitter is designed to be used in conjunction with a Teledyne Analytical Instruments probe
model 9060H or 9060UL/UH. These two probes use a zirconia sensor that must operate at >650°C.
The 9060H probe has an integrated heater, and the 9060UL/UH probe uses the process heat to heat
the sensor. There is a unique cable connection between the 9060Z transmitter and the
9060H/9060UL/UH probe.
The model 9060Z oxygen transmitter is based on the well known model 9060H transmitter. It includes
a number of hardware and software improvements such as a graphic display, larger characters, faster
microprocessor, simplified set up menu, alarm logging, faster probe heater control and more
calculated values such as burner efficiency.
The 9060Z Oxygen Transmitter has a variety of user‐selectable functions. They are simple to use
because each selection is menu driven. For options you are not sure about, read the manual on that
particular item in chapter 6, Setup Mode.

The oxygen deficiency output can be used in the same way as a combustibles analyzer to signal the
extent of reducing conditions of combustion processes.
4. INSTALLATION AND COMMISSIONING
4.1 MOUNTING THE TRANSMITTER
Surface mount the transmitter case on to a flat surface or bracket, using the four mounting brackets
provided. The transmitter should never be mounted so that it is directly expose to the sun or rain.
Always leave at least 10cm of clearance around the four sides of the case.
Make sure the temperature of the case is below 55°C, and that the radiated heat from furnaces and
boilers is kept to a minimum. There should be adequate ventilation to maintain ambient temperature.
Install the cables through cable glands. There are 4 holes cut in the base of the transmitter case; 2x
17mm & 2x 21mm. Use a sharp knife to cut away the covering film for only the glands that are
needed.
NOTE: ALWAYS LEAVE THE UNUSED GLAND HOLES SEALED.
Ensure that the electrical connection complies with the local electrical requirements. (see chapter 4.6,
Electrical Connections)
4.2 INSTALLING A 9060H OXYGEN PROBE
Weld a BSP or NPT socket to the flue in a suitable position for flue gas sensing. For the correct size of
socket refer to probe data in chapter 3.1.3. The closer to the source of combustion the smaller will be
sensing lag time, allowing better control.
The probe has a typical response time of less than four seconds, so most of the delay time is normally
the transit time of the gas from the point of combustion to the point of sensing.

Model 9060Z Manual
Probes can be mounted at any angle. However, if the probe is to be mounted on a vertical duct wall, it
is better to angle the probe (approx. 15°) down to avoid process condensation inside the cold end of
the probe. If there are any particulates in the flue gas, a filter can be omitted by pointing the probe
vertically downwards. Otherwise the transmitter can be configured to automatically purge the filters
or they can be replaced periodically.
,
Oxygen Probe Mounting
CAUTION
It is important that there is no air in leakage upstream of the oxygen sensing point otherwise
there will be a high oxygen reading.
If the probe is to be installed on a bend in the flue, it is best located on the outer circumference
of the bend to avoid dead pockets of flue gas flow. While the standard 9060 probe with a ‘U’
length of 250 mm (10”) will suit most low temperature flue applications, it is occasionally
necessary to have a longer probe with the sensing tip in the centre of the flue gas stream.
Although it is rare, occasionally a probe may sense oxygen vastly differently from the average
reading in the flue gas. If it occurs, then the probe should be moved, or a longer probe
installed. This phenomenon is normally caused by stratification of the flue gas.

Model 9060Z Manual
4.3 INSTALLING THE AUXILIARY THERMOCOUPLE
Weld a 1/2 inch BSP mounting socket to the flue within about 300 mm (12”), and upstream of the
oxygen probe. The thermocouple should be of similar length to the oxygen probe to prevent flue
temperature distribution errors.
The thermocouple should be connected to terminals 7 & 8. These terminals will not be available for an
auxiliary thermocouple if a second probe has been installed.
4.4A SHIELD CONNECTIONS
All external wiring to the 9060Z transmitter should be shielded. Do not connect shields at the field
end. Simply clip off and insulate. There are two M4 earth screw terminals available in the 9060Z
transmitter. An extra terminal strip may be required to connect all shields together. This should be
supplied by the installer.
4.4B EARTH CONNECTION (PE)
The PE (protective earth) input connection must be made to the earth stud on the right hand side of
cabinet. The PE input connection must be the first connection onto the earth stud and it must be
secured by a separate nut and spring washer. All other earth connections (bonding connections) can
be made on either of the two earth studs in the base of the cabinet.

• The mains power must be either 100/110VAC or 220/240VAC with a mains frequency of 50 or 60Hz
• The supply circuit must be fused to at least 10Amps and have a dual pole isolation switch within
easy access of the oxygen transmitter. The isolation switch must be marked as the isolation switch
for this equipment. It is recommended that a separate isolation switch be used for each transmitter
so that a transmitter can be serviced individually.
• The power supply cables must be supplied and installed according to local regulations
• The earth connection must comply with the local regulations must have a current carrying
capability
equal or greater than the supply fuse current rating
• The earth connection must be connected to the primary earth stud inside the transmitter on the
right hand side
• All other bonded earth connections from the external wiring must be connected to the primary
earth stud.
All operations relating the electrical wiring and installation must be carried out by qualified persons in
accordance with the safety regulations and the wiring rules.
NOTE: The power switch in the transmitter can be used to turn off the transmitter. There must be an
approved isolation device installed to provide complete isolation of the mains power to the
transmitter. The mains wiring terminal must not be used as an disconnect device.
4.6 HEATER INTERLOCK RELAYS
CAUTION
Explosion protection for heated probes is achieved by switching the power to the probe heater off
whenever the main fuel valve is closed.
The principle of safety is that if the main fuel valve is open then main flame has been established. With this
primary source of ignition on, the probe heater can be safely switched on. The most dangerous situation is if
fuel leaks into the combustion appliance when the fuel valve is closed. When power is removed from the
main fuel valve the heater should also be switched off.
To achieve this protection, connect a main fuel valve voltage free contact to the ‘BURNER INPUT’ terminals
10 & 11. When the main fuel valve is open, the voltage free contact should be closed. For installations
where there is no risk of explosion, connect a link between terminals number 10 & 11.
Heater Supply Interlock Connection for Heated Probes
If a safety interlock is not required, a wire must be connected between terminals 10 &11 to enable –
• The heaters on heated probes
• Process alarms
• Auto‐purge and auto‐cal checking
• Run time timer
4.7 CONNECTING AN OXYGEN PROBE CABLE
Connect the probe lead as shown in the following drawings. Unheated probe leads have integral
reference air tube. An adaptor has been supplied to connect this tube to quarter inch flexible PVC
tubing, from the air pump or reference air supply.

4.8 CONNECTING THE AUXILIARY THERMOCOUPLE (OPTIONAL)
For 9060H heated probes, the auxiliary thermocouple must be a separate TC with the junction
isolated from earth, mounted near to and upstream of the oxygen probe. It can be either a K, J, R or S
type thermocouple. It is optional. If the auxiliary temperature or combustion efficiency is not to be
displayed or transmitted, then an auxiliary thermocouple is not necessary. The thermocouple should
be connected to terminals 7 & 8. These terminals will not be available for an auxiliary thermocouple if
a second probe has been installed.
4.9 CONNECTING THE OUTPUT CHANNELS
The two 4 to 20 mA DC output channels are capable of driving into a 1000Ω load. The output
terminals are 12 & 13 for channel 1, and 14 & 15 for channel 2.
4.10 CONNECTING THE ALARMS
A common alarm, which should be connected for all installations initiates on alarm functions
described below. Three additional alarm relays are available for selectable functions as listed in
chapter 9.2. Each relay has normally open contacts. The contacts will open in alarm condition. Relays
are connected as follows:
Relay Common Alarm
Terminal Numbers 26 & 27
Alarm 1
Alarm 2
Alarm 3
28 & 29
30 & 31
32 & 33

4.11 CONNECTING THE AUTOMATIC PURGE AND CALIBRATION CHECK SYSTEM
CAUTION
The purge and calibration solenoid valves are supplied with mains voltage. This supply has
electrical shock danger to maintenance personnel. Always isolate the transmitter before working
with the purge and calibration solenoid valves.
22
Download from Www.Somanuals.com. All Manuals Search And Download.
Model 9060Z Manual
The on‐line auto purge and calibration check system is optional. For details on its operation see
chapters 4.24, 4.25 and chapter 11.
To automatically sense a blocked probe filter, a flow switch should be installed in the ‘purge’ line to
the probe ‘CAL’ port. It should be adjusted so that it energizes just below the purge flow with new or
clean filters installed. The flow switch contacts should be connected to terminals 16 & 17 (FLOW SW).
If the filter is still blocked or partly blocked after an auto purge cycle, the flow switch will not energize
and will therefore cause a ‘Probe1 (2) Filter Blocked’ alarm.
After installation the purge/cal system should be tested thoroughly for leaks. Any leaks can cause
significant errors if the flue is at negative pressure. If the flue is at positive pressure, an outward leak
can cause corrosion in the purge/cal system piping and fittings.
If probe/filter purging is required but a “Probe1 (2) Filter Blocked” alarm is not required, do not install
the flow switch but link terminals 16 &17.

4.12 CONNECTING REFERENCE AIR
For oxygen probes, a 1/4” tube connector on the transmitter should be connected via a nylon, copper
or stainless steel tube to the ‘REF’ connector on the probe. If two probes are being used, a “T” fitting
must be supplied to provide reference air supply to both probes.
4.13 CONNECTING THE TRANSMITTER TO A MODBUS™ NETWORK
The transmitter can be networked to other transmitters and to a network master. The network uses
the transmitter’s RS485 port. Up to 31 transmitters can be connected to the network, and can be
interrogated by the Network Master.
NOTE: Hardware Protocol Selection The communications port of the 9060Z can be configured to
communicate on either RS232 or RS485. If the transmitter is to be used on a MODBUS network, the
9060Z transmitter must be set to RS485. For further details see chapter 7.2.25, Communication Port
Options.
NOTE: Terminating Resistor There is a terminating 100 ohm resistor fitted to the 1732‐1 PCB. Link LK3
(TERM), in the bottom left‐hand corner of the PCB, is used to connect the terminating resistor. Link
LK3 must be removed on all transmitters except the transmitter on the end of the network line. If the

4.14 ONNECTING POWER
Before commissioning the probe, sensor or transmitter, read the CAUTION paragraphs at the front of
this manual. The green & yellow EARTH wire MUST be connected to earth.
4.15 COMMISSIONING ‐ RUN MODE
When the transmitter is turned on it will go to RUN mode. The SET‐UP/RUN button will toggle
between the two modes. The upper line of the display will now read ‘% OXYGEN’. If the probe or
sensor temperature is not above 650°C (1200°F), a “Probe Low Temperature” message is flashed on
the lower line. The probe or sensor temperature can be checked on the lower line of the display.
4.16 PROBE OR SENSOR CALIBRATION
The zirconia sensor provides an absolute measurement of oxygen partial pressure. There are no
calibration adjustments, apart from ‘Probe 1 Offset’, for the probe. The zirconia sensor EMF is either
correct or it needs to be replaced. To check that the probe is functioning correctly, first check that the
24
Download from Www.Somanuals.com. All Manuals Search And Download.
Model 9060Z Manual
high impedance alarm, ‘Probe 1 (2) High Impedance’, is not active. The actual impedance can be
displayed on the lower line. It should be less than 9 KΩ at 720°C (1320°F).
Once it has been established that the impedance is normal, the offset may be set using the millivolt
value marked on the oxygen probe. See chapter 6.3.1, Probe Offset. The probe offset can be tested on
site. A small flow of air must be admitted to both the ‘REF’ and ‘CAL’ ports when testing the probe
offset. If the probe is in the process, the air must fully purge the probe sensor without interference
from the process gas sample. Teledyne Analytical Instruments probes can easily achieve this with or
without a probe filter and a gas flow of only 1 to 5 SLPM (2 to 10 SCFH) for a 9060H probe and up to
20 SLPM (40 SCFH) for an unheated probe. When a stable oxygen reading has been achieved, read the
‘Probe EMF’. Enter this value into the set‐up menu #1 for the probe 1 (set‐up #2 for the second probe
if it is installed).
4.17 FILTER PURGING
Purging probe filters is controlled from the ‘GAS/PURGE’ buttons on the transmitter when in ‘RUN’
mode. If ‘Automatic’ has been selected in either ‘Sol. 1 Auto/Man’ or ‘Sol. 2 Auto/Man’ in
Commissioning Menus 21 or 30, pressing the GAS/PURGE button will start the automatic cycle.
Pressing the button again will cancel the auto purge cycle. If ‘Automatic’ was not enabled, the
solenoid will only stay open for as long as the button is pressed. Gradually adjust the purge air supply
regulator, increasing the pressure until sufficient flow is obtained to clear the filter. This is best
checked with a dirty filter after a period of operation, by withdrawing the probe from service and
watching any build up on the filter being blown off at the set pressure. Normally 30 kPa (5 psi) is
adequate but the air pressure may be set as high as 100 kPa (15 psi).
4.18 CALIBRATION GAS CHECK
If the installation has a filter purge facility, set this up first. Refer to the previous paragraph. Press the
‘GAS/PURGE 1 or ‘GAS/PURGE 2’ button while in ‘SET UP’ mode to obtain a reasonable flow through
the calibration check gas flow meter. If air is being used as a calibration check gas, use the air from the
regulator for filter purge. Then, when setting up a gas for calibration checking, set the pressure from
the calibration gas cylinder so that it is the same as the pressure set on the air regulator. Then the
setting on the rotameter / flow regulator will be the same as that for the airflow. The flow required is
1 to 5 SLPM (2 to 10 SCFH) for a 9060H probe and up to 20 SLPM (40 SCFH) for an unheated probe.
Air is not the best gas for calibration checking on a zirconia sensor. The output of a zirconia sensor
with air on both sides of the sensor is zero millivolts. It is better to choose a gas value which provides
a reasonable output from the sensor and which is near to the process oxygen level. A cylinder with 2%
oxygen in nitrogen is a commonly used calibration gas. The maximum pressure on the calibration
check gas cylinder regulators is 100 kPa (15 psi).
Note: If ‘Dual probe’ was selected in commissioning menu 4, ‘Cal Gas 2’ must be connected to probe 2.
4.19 DUST IN THE FLUE GAS
For unheated probes with no filter, entrained solids or dust in the flue gas does not present a
problem unless the dust, when settled, is not porous. Allow the dust in the process to build up on
the probe. It will form a porous layer slowing the response time. To avoid mechanical abrasion of
the electrode material in installations with unheated oxygen probes, pack ‘SAFFIL’ or equivalent
alumina based ceramic fiber in the sensing holes to protect the electrode. Do not use silica based
ceramic fibers such as ‘KAOWOOL’, which can attack the electrode at high temperatures. Once the
dust has built up the response time of the probe will be slower.
For heated probes the preferred method of mounting for dust‐laden applications is facing vertically
25

Model 9060Z Manual
downwards with the filter removed. Probes can also be mounted horizontally with no filter with some
dusts. An occasional automatic back purge is helpful in this case.
Normally heated probes are supplied with filters for applications with particulates in the flue gas. The
probe response time should be tested when the probe is first installed, and then regularly until it
remains constant for a significant period. Filter purging should be set up on the time periods
determined by these tests. To test the probe response time, use a stopwatch to obtain the time for a
probe to achieve a 63 % change from one reading to another. If a probe filter blocks completely in a
short period of time, then there is no option but to use the probe without the filter. A trial probe with
filter can be installed to test whether a filter blockage is likely to occur.
4.20 STRATIFICATION
If the transmitter and probe have been fully tested and the oxygen readings in the flue gas are
incorrect, gas stratification may be occurring. The phenomena cannot be anticipated for any particular
installation. Generally, large flues have oxygen differences of approximately one percent across the
flue. Occasionally an oxygen error of several percent may occur in a flue of any size. Moving the probe
to a new location normally solves this problem. The effects of stratification can be reduced by using
two probes and averaging the two oxygen readings. This can be achieved within a Teledyne Analytical
Instruments 9060Z transmitter controlling two probes.
4.21 CONNECTING A PRESSURE TRANSDUCER
If the process gas pressure varies more than 4" WG and therefore requires automatic compensation,
connect a pressure transducer as shown below. Place a link across LK2, near to the input terminals 24
& 25. If the link is not populated, you can achieve the same thing connecting a 120Ω resistor across
the two terminals. A pressure change of 4" WG will cause a change in the calculated oxygen reading
of approximately 1%.
There are no calibration adjustments for the zero or span of the pressure transducer input. Set the
transducer scale range in the commissioning menu ‐ See Section 7.2.8. The pressure can be displayed
on the lower line by enabling the corresponding option. See Section 6.3.2.

5. DISPLAY AND KEYPAD
Operator interaction with the oxygen transmitter is done through a graphical display and 8 keys on
the front of the case. The five LED indicators are used to show the status of the transmitter and to
alert the operator of any errors.
Each of the keys has a dual function;
The BLACK text printed on the key is the function while the transmitter is in the RUN mode
The WHITE text printed on the key is the function in one of the three configuring menus, (SETUP,
COMMISSIONING and CALIBRATION)
The menu driven modes are accessed by pressing, and in some cases holding down, the SETUP key
(see chapters 6, 7 and 8 for details of these modes). The transmitter will return to the RUN mode
when the SETUP key is pressed again, or if 60 seconds has elapsed since the last key was pressed
.
5.1 Graphical Display
In RUN mode the 9060Z shows the first oxygen probe measurement in large characters at the top of
the display and a user selectable lower line in smaller characters below. Other items on the display
include the activity heartbeat indicator in the top right corner, a row of single letter action indicators
in the bottom left corner and the current time in the bottom right corner.
In SETUP mode the RUN display is replaced with a menu driven interface. All other functions of the

CALIBRATION modes (see chapters 6, 7 and 8 for details). The function of all the keys will then change
to the functions that they have in the SETUP mode.
DISPLAY UP / DOWN keys
The display keys are used to scroll the lower line up and down through the variety of measurements
that are available on the lower line. For a complete list of options see chapter 6.3.2, Lower Line Items.
ALARM UP key
If there is either a new alarm or an active alarm the ALARM UP key can be pressed to examine the
alarm status. The alarm light will be flashing if there is a new alarm or steady if there is an existing
alarm. For more details on the alarm mode and keys see chapter 9, Alarms. The SETUP light will flash
slowly to show that the transmitter is now in the alarm display mode.
ALARM DOWN key
When the transmitter is displaying active alarms (the ALARM UP key has been pressed), the ALARM
DOWN key and the ALARM UP key allow the operator to examine the date / time of the alarm and the
date / time that the alarm was acknowledged.
If the transmitter was in RUN mode when this key is pressed it will go into the alarm log display mode.
See chapter 9 for more details.
ALARM ACCEPT key
The ALARM ACCEPT key is used to accept a new alarm (see chapter 9, Alarms).
GAS 1 / PURGE 1 and GAS 2 / PURGE 2 keys
These two keys are used to turn on the gas / purge solenoids. When the transmitter is in the manual
cal / purge mode (Commissioning functions #21 and 30) the solenoid will be activated for as long as
the key is pressed. When the transmitter is in the auto cal / purge mode the automatic cal / purge
cycle is started. The cycle can be stopped by pressing the same key again.
5.3.2 Keypad in SETUP / COMMISSIONING / CALIBRATION modes
NOTE: In order to enter either COMMISSIONING or CALIBRATION modes, the corresponding DIP
switch on the 1732‐1 PCB must be turned on.

Probe impedance key
When this key is pressed the transmitter will measure the impedance of oxygen sensor(s) attached to
the transmitter. If the burner is not enabled (terminals 10 & 11) or the probe temperature is below
700°C (1292°F) impedance checking will not be performed. A ‘Z’ will be seen in the bottom left hand
corner of the display as the test is performed.
Auto calibrate key
When this key is pressed the transmitter will calibrate the analogue output channels that are set to
auto calibration (see chapter 10). This is performed by directing the output current away from the
output terminals (terminals 12&13 and 14&15) back to an analogue input to the transmitter in order
to calculate a zero and span calibration factor for each of the output channels.
During this process normal output to the analogue channels will be interrupted sending the outputs to
zero mA.

6.3 SETUP MODE FUNCTIONS
6.3.1 Probe 1 Offset
Each Teledyne Analytical Instruments probe has an offset calibration value printed on a tag that is
attached to the probe when it is dispatched. To achieve accurate measurement the offset value must
be entered with the same polarity as it is printed on this label. The offset value should be within
±1.0mV
NOTE: An offset of 1.0mV will change the oxygen reading by approximately 1% oxygen when the
probe is in ambient air. However, as the process oxygen measurement drops, this offset will have a
reduced affect. At a process gas oxygen concentration of 2%, the 1.0mV offset error will only change
the reading by 0.1% oxygen.
If in any doubt about the correct offset value, set it to 0.0mV.
The function ’Probe 2 Offset’ will only appear if the transmitter has been configured for 2 probes. (see
chapter 7.2.3 Number of Probes )
6.3.2 Lower Line Items
This function allows the operator to change the items that are available to be displayed on the lower
line of the transmitter in RUN mode. If the word “Enabled” appears on the display for a selected lower
line option, the measurement will be available to be shown on the display in the RUN mode by
scrolling through the list using the DISPLAY UP and DISPLAY DOWN keys.
A lower line measurement can be “Enabled” or disabled by pressing the ENTER key.

6.3.3 Oxygen Display Units
The top line of the display that shows the oxygen measurement can be displayed in either % or ppm
(see chapter 5.2 Oxygen Display Units)
6.3.4 Damping Factor
The oxygen measurement can be damped by averaging successive readings from the probe. This will
smooth out fluctuations in the process gas level and will slow down the reaction time of the
transmitter. The larger the number selected here, the more successive readings are averaged and the
smoother the measurement will be. The damped oxygen value is also used in the calculation of all
other parameters that are based on the oxygen value.
6.3.5 Process Alarms
This function allows the operator to enable and disable process alarms. The process alarm menu
functions will also be hidden if the process alarms are disabled. (See also chapter 7.2.19, Process
Alarms)

readings and gas calibration checks. The correct date and time should be entered by pressing and
holding the OPTION UP & DOWN keys. The date and time will change faster the longer the OPTION
key is held.
7.2.2 Service Date
The service date can be used to keep a record of when a probe was changed. The RUNTIME timer
which keeps a track of the hours and minutes that the transmitter and probe has been operating is
reset when the service date is changed.
The service date and the runtime timer can be displayed as lower line items in RUN mode.
7.2.3 Number of Probes
The 9060Z transmitter can operate in single or dual probe mode. By selecting single probe, all dual
probe options and alarms will be disabled and second probe options hidden from the user.
If you are using the transmitter as a single probe device you should set the number of probes to
‘single probe’ to disable all probe 2 alarms and display items.
7.2.4 Probe 1 & 2 Type
The probe type function allows a selection between a heated probe and an unheated probe types.
Heater control and alarms will be disabled if unheated probe type is selected.
7.2.5 Probe 1 & 2 Thermocouple Type
The thermocouple type can be set to K, J, R or S. The thermocouple in the Teledyne Analytical
Instruments 9060H heated probes are always K type. 9060UL/UH unheated probes are available in R
type or S type. Other thermocouple options are made available for special installations.
7.2.6 Auxiliary Thermocouple Type
When the transmitter is operating as a single probe mode, the probe 2 thermocouple input (terminals
7&8) is used as an auxiliary thermocouple input. In dual probe mode this option is unavailable.
Use of an auxiliary thermocouple allows for basic monitoring of temperature as well as enabling the
calculation of combustion efficiency. The thermocouple type can be set to K, J, R or S.
7.2.7 Transmitter Output Channel 1 & 2
The 9060Z transmitter has two fully configurable 4‐20mA analogue outputs. The channels can be
configured independently to output one of several calculated values.

Model 9060Z Manual
The zero and span of the selected output are set in the following two menus (functions 11&12 and
14&15).
NOTE:
Regarding channel output configuration; both 4‐20mA channels are separately isolated and output
variables and scaling are individually configured for each channel.
In single probe mode both channel 1 and 2 have identical options, however when the analyzer is
configured as dual probe then channel 1 will output process variables relative to probe 1 and
channel 2 will output process variables relative to probe 2.

7.2.8 Flue Pressure Units and Value
The 9060Z transmitter is capable of fixed or variable input pressure compensation in the calculation of
oxygen from ‐1 Atm to +3 Atm. If the probe is running in a pressurized environment this value should
be set to allow for accurate oxygen measurement. If the flue pressure is constant select 'Fixed" in this
function and set the pressure units and value in the proceeding menus. If the pressure varies, select
"Variable", and connect a pressure transducer to terminals 24 & 25. (See section 4.23). Set the range
of the transducer using a zero and span value in the commissioning menus.
7.2.9 Temperature Units
The display on the transmitter can be changed to show temperature in either Celsius or Fahrenheit
scales.
7.2.10 Calibration Freezes Outputs
During gas calibration checks it may be required that the analogue outputs remain frozen at their last
reading. When cal freezes is enabled both analogue outputs remain frozen until the entire calibration
cycle has completed.
7.2.11 Solenoid 1 & 2 Operation
The two solenoid outputs can be individually configured to perform gas calibration check or probe
purge.
Some of the menus between functions 22 to 28 (31 to 37) will not appear depending on what has
been selected in function #20 and #21 (29 and 30).
7.2.12 Solenoid 1 & 2 Automatic / Manual
When set to automatic the solenoid will perform a pre‐programmed gas calibration or purge cycle.
When set to manual the solenoid is controlled directly from the corresponding key on the front of the
case. When set to automatic the calibration check or the purge cycle can be started by pressing the
corresponding key on the front of the case. It can be stopped by pressing the same key again.
7.2.13 Solenoid 1 & 2 Start Time
For automatic gas calibration checking or purge events a start time is specified to allow precise control
over the timing of such events. Starting at this specified time, the next gas calibration or purge event
will occur in successive intervals from this time.
7.2.14 Solenoid 1 & 2 Period
This option specifies the period between automatic gas calibration or purge events. For periods less
than 24 hours the period is divisible into 24 hours forcing scheduling of events to occur at the same
time each day between 1 minute and 7 days.
The ‘No Timed Operation’ option accessible by scrolling the option below 1 minute allows for pre‐
configured solenoid cycles to be triggered manually via the keypad, but without the automatic
scheduling.

8.2 CALIBRATION MODE FUNCTIONS
8.2.1 REFERENCE VOLTAGES
The calibration of the analogue inputs is based on the voltage of a temperature compensated voltage
reference integrated circuit. There are 4 voltages generated from the standard reference voltage.
They will vary by about 1% from one transmitter to another but can be trimmed by setting the actual
voltages into CALIBRATION menu functions #1 to 4. These voltages should be measured and the
reference voltage entries in the menu checked every year.
8.2.2 OUTPUT CHANNEL 1 AND 2 CALIBRATION
The output 4‐20mA calibration can be set either AUTOMATICALLY (default) or MANUALLY. If Auto
Calibrated is selected the transmitter will go through an output calibration cycle when the power is
turned on or when the AUTO CAL button is pressed in SETUP mode. This will divert the outputs back
to the input and automatically set the 4mA and 20mA calibration.
If Manually Calibrated is selected then the 4mA and 20mA calibration must be set in the next two
functions. For the full explanation see chapter 10.1.2.
8.2.3 AMBIENT TEMPERATURE CALIBRATION
The ambient temperature measurement is used as the cold junction temperature for the
thermocouple measurements. Use an independent temperature sensor to measure the temperature
inside the transmitter case near the screw terminal #1. Enter this temperature into the calibration
function 11 by using the OPTION keys and then the ENTER key.
8.2.4 LOW OXYGEN CALIBRATION
The low oxygen calibration factors can be used to fine tune the oxygen calculation at low oxygen
readings. It will not affect the measurement at 20.9%. They are included to allow oxygen probes made
by other manufacturers to be used on a Teledyne Analytical Instruments transmitter. The default is
100% but can be set to between 80 and 120%.
8.2.5 TRANSMITTER OUTPUT SCALE
The transmitter outputs can be configured to either 4‐20mA or 0‐20mA. The two scaled outputs are
capable of outputting 0‐24mA and will transmit over‐scale unless the over‐scale limit option is
selected.
8.2.6 TRANSMITTER OUTPUT LIMITING
If the oxygen reading is invalid the output can be made to be set to 0mA, 4mA or 20mA. An invalid
reading is when the probe temperature is below 650°C (1200°F) or the probe thermocouple has been
detected as open circuit. The default is to set the output to 20mA but the function can also be
disabled.
8.2.7 MAINS VOLTAGE DETECTION
The default setting for the 9060Z transmitter is that it will automatically detect the mains voltage and
frequency in order to correctly drive the probe heaters. If there is any uncertainty in this detection
system the voltage can be forced to 220‐240 or 100‐127, and the frequency can be set to 50 or 60Hz.

8.2.8 HEATER SSR FAULT CORRECTION
In the event of one of the heater solid state relays (SSR) failing in single probe mode, the heater drive
output can be swapped to the HEATER 2 output. Select “Heater 1<‐> Heater 2”.
If you are running in dual probe mode but not using the calibration gas or purge solenoid outputs the
solenoid outputs can be swapped to the 2 heater outputs. Select “Heaters <‐> CalPurge”. The default
setting is “Normal”.
8.2.9 SSR FAIL PROTECTION
The transmitter continuously monitors the high voltage outputs on the solid state relays that power
the probe and purge/cal solenoids. If it detects that any solenoids are not switching off correctly then
it mechanically isolates all high voltage outputs in order to protect the instrument. This feature can be
switched off by setting the SSR fail protection to disabled.

The common alarm relay is used to monitor faults within the transmitter and the probe. The other
three alarm relays relate to the process gas. All relays have user defined actions.
If one of the alarm events is removed from the common alarm using COMMISSIONING menu function
#49, then this alarm event can be programmed for one of the other 3 alarm relays.
When the alarm mode has been entered, the SETUP light flashes once a second until the SETUP key is
pressed to return the transmitter to RUN mode.
All relays have fail‐safe alarm contacts. That is –
When the transmitter is turned off the contacts are open circuit
When the transmitter is on but there are no alarms the contacts will be closed
When there is a current unaccepted alarm event the contacts will be open circuit
When there is a current accepted alarm event the state of the contacts will depend on the
selection in the commissioning menu #50. See chapter 7.2.22, Operation of the alarm relay when
an alarm is accepted.
All alarms drive the alarm light on the front door.
The light will be off if there are no alarms current
The light will flash if there is a current alarm that has not been acknowledged
The light will be on steady if there are current alarm(s) that have not been cleared
The light will flash faster as more alarms occur
9.1 COMMON ALARMS

probe #2 is greater than the trip level shown in COMMISSIONING menu function #44 for longer than
the delay time shown in function #45.
28. ‘Probe 1 Temperature Low’
29. ‘Probe 2 Temperature Low’
The probe temperature is under 650°C (1200°F). The oxygen reading is therefore invalid. If the probe
heater has been on for more than 20 minutes and the temperature is less than 650°C (1200°F) a
‘Probe # Heater Fail’ alarm will occur.
NOTE: The ‘Probe # Temperature Low’ relay function is used with unheated probes to indicate oxygen
reading is invalid (the probe is below 650°C (1200°F) ), in case the process temperature falls below this

10. INSTRUMENT CALIBRATION
10.1 CALIBRATION SUMMARY
The 9060Z oxygen transmitter has a self calibration and diagnostic system built into the hardware and
software. Once the reference voltages have been set into memory the self calibration system
maintains the calibration of the transmitter. An automatic update of the zero and span is done every
minute.
The 4‐20mA outputs can be automatically calibrated with the press of the AUTO CAL key or manually
fine tuned.
One entry for each probe offset is required to optimise the calibration of the oxygen measurement
although an automatic system calibration check can be programmed into the transmitter using
certified gasses.
10.1.1 CALIBRATION OF THE INPUTS
The calibration of the analogue inputs is based on the voltage of a temperature compensated voltage
reference integrated circuit. There are 4 voltages generated from the standard reference voltage.
They will vary by about 1% from one transmitter to another but can be trimmed by setting the actual
voltages into CALIBRATION menu functions #1 to 4.
The calibration should be done 30 minutes or more after the instrument has been on, approximately
once every year. The calibration constants are retained in battery backed memory unless a ‘COLD
START’ is performed. See chapter 10.2, Cold Start.
Connect a 3 1/2 digit multimeter negative lead to the test point marked ‘COM’ in the centre of the
1732‐1 PCB (labeled ‘V‐REFS’). Measure the four voltages on the test point marked 1 to 4 with the
positive lead of the multimeter. Enter the measured values in the CALIBRATION menu functions #1 to
4. Whenever new values are entered, the D/A Section should be re‐calibrated. See chapter 10.1.2.
10.1.2 CALIBRATION OF THE OUTPUTS
The easiest way to calibrate the outputs is to select ‘Auto Calibrated’ in CALIBRATION menu functions
#5 and 8. If this is selected the outputs will be directed away from the output terminals and back into
an analogue input of the transmitter. The outputs are then tested and a zero and span calibration
factor is recorded. If a more accurate calibration is required select ‘Manually Calibrated’ in
CALIBRATION menu functions #5 and 8. This will inhibit the automatic calibration system overwriting
the calibration factors. However, the zero and span factors will need to be manually set. To set the
calibration factors use the following steps for each output:
1. Select CALIBRATION menu function #5 (8) and set the option to ‘Calibrate 4mA’.
2. Use the FUNCTION up key to go to function #6 (9).
3. Set this to 4.00mA and press the ENTER key.
4. Measure the actual output current with a digital multimeter.
5. Use the OPTION keys to set the option to the value read on the digital multimeter and press
ENTER.

11. The output should go 20.00mA. The value in function #7 (10) can be fine tuned if necessary.
12. Go back to function #5 (8) and select ‘Calibrate 4mA’ again and check that the output is still set
to 4.00mA. If it is not exactly 4.00mA the value in function #6 (9) can be trimmed again.
13. Go back to function #5 (8) and select ‘Manually Calibrated’.
10.1.3 PROBE CALIBRATION
There is only one calibration factor for the calibration of the oxygen probe. This is the sensor offset,
and it is written on a tag attached to every probe.
Use the FUNCTION keys to go to SETUP menu #1 (2) and then use the OPTION keys to set the value to
the value written on the tag. If in doubt the best option is to set the offset to 0.0mV because this will
only produce an error of around 0.1% oxygen in a combustion application for a 1mV error in the offset
value.
For information on checking the probe and transmitter system with a certified gas see chapter 11.
10.2 COLD START
The intention of the cold start function of the transmitter is to return all of the configuration set up
back to the default values. There are 3 parts to the cold start:
1. If a software upgrade is installed and the changes require a change to the menu functions then
the transmitter will automatically do a cold start. The transmitter will also do a cold start when
the power is turned on and the configuration / calibration factors are found to be corrupted. It
will only reset either the configuration values or the calibration values if either of them is
found to be corrupted.
2. A cold start can be forced if the operator wants to reset the transmitter back to the default set
up. See chapter 10.2.1, Forcing a Cold Start.
3. Resetting the calibration factors back to the default values. See chapter 10.2.2, Resetting the
Calibration Factors.
10.2.1 FORCING A COLD START
The cold start can be initiated by following these steps:
1. Turn the transmitter power off.
2. Use a fine point or screw driver to turn the COLD START switch on. The switch is at the bottom
of the 1732‐1 PCB, accessible through the window in the shield.
3. Turn the transmitter back on.
4. You will be prompted to select ‘Reset’ or ‘Cancel’ to the prompt ‘Reset Calibration Data?’.
Press the DISPLAY up key to reset the calibration factors and the configuration data or the
ALARM up key to only reset the configuration of the transmitter.
5. Turn off the cold start switch when prompted by ‘Turn off C/Start Switch’.
If the calibration factors have been reset, follow the instructions in chapter 10.1 to recalibrate the
transmitter. If only the configuration has been reset it is also important to check items that will affect
the transmitter outputs, number of probes, the serial communications, the solenoid configuration and
other items.
10.2.2 RESETTING THE CALIBRATION FACTORS
If it is required to reset the calibration factors, follow the instructions in the previous section and
select ‘Reset’ when prompted to ‘Reset Calibration Data?’.

11. GAS CALIBRATION CHECK AND PURGE
The oxygen sensor that is used in the Teledyne Analytical Instruments oxygen probe is extremely
predictable, stable and reliable. For this reason, the calibration of a Teledyne Analytical Instruments
oxygen system does not require the use of calibration gases. However, all Teledyne Analytical
Instruments oxygen probes have a built in gas connection that does allow the accuracy of the probe to
be checked in‐situ. This chapter describes the operation of this gas checking system.
The 9060Z has a timer and solenoid driving system that can be configured to admit a certified
calibration gas into the probe or an air supply to purge the probe filters through the gas connection.
Both the calibration gas and the filter purge gas must be piped to the port on the probe labeled “CAL”.
There are two solenoids drivers in the 9060Z transmitter. They can be used for any combinations of
gas checking and probe filter purging. The only limitation is that if the transmitter is in dual probe
mode, then solenoid #1 must be wired and plumbed to the probe #1 and solenoid #2 must be wired
and plumbed to probe #2.
The transmitter can also be configured to be in a MANUAL or AUTOMATIC purge and gas check mode.

11.1 PURGE
For processes that have particulate present in the gas stream, probe filters are necessary and should
be back‐purged with sufficient frequency to avoid blocked filters. Select ‘Purge’ in function #20 (29)
and ‘Automatic’ in function #30 and then set the times in function #22 (31) to #25 (34) The outputs
can be frozen during purging if selected in COMMISSIONING menu function #19. A flow switch can be
wired to terminals 16 and 17. If the flow is not sufficient at the end of the purge cycle to close the
contacts of the flow switch a ‘Probe 1 (2) Filter Blocked’ alarm is generated. If a flow switch is not
being used a short circuit should be placed across terminals 16 and 17 to suppress the ‘Probe 1 (2)
Filter Blocked’ alarm.
11.2 CALIBRATION GAS
If it is required to automatically check the oxygen probe and transmitter on line, select ‘Calibration
Gas’ in function #20 (29) and ‘Automatic’ in function #30 and then set the times in function #22 (31)
to #25 (34) and the gas levels in function #26 (35) to 28 (37). If the transmitter measurement does not
fall within the limits set in function #26 (35) to 28 (37) a ‘Gas1 (2) Calibration Error’ alarm will be
generated. If the transmitter has ‘Automatic’ selected in function #21 (30) and one of the GAS/PURGE
keys is pressed in RUN mode, the automatic cycle will be started and the alarms will be checked. The
cycle can be stopped at any time by pressing the same key during the cycle.

12. SOFTWARE UPGRADES
The software for the 9060Z series transmitters is contained in memory inside the microprocessor
integrated circuit (IC). The transmitter therefore does not require an external memory IC for the
software. Provision has been made to enable the software to be upgraded in the field without the use
of a computer. If an upgrade is to be made to the software it will be supplied in a 32 pin EEROM IC
type 29F010B. To do the upgrade, use the following steps:
1. Turn the power off to the transmitter at the power switch
2. Remove the hose from the reference air pump (if fitted)
3. Unplug the reference air DC power lead (if fitted)
4. Undo the two M4 screws at the top and bottom of the main shield
5. Remove the earth screw from the main shield on the right hand side of the cabinet
6. Lift out the main shield around the cable glands
7. Fold out the two wings of the blue socket labeled “FIRMWARE UPGRADE SOCKET”. Plug the
29F010B into the socket. Carefully note the direction of the IC. Pin 1 is identified on the PCB and
pin 1 on the IC has a small round indentation next to the pin.
8. Hold down the DISPLAY down and the ALARM LOG keys and then turn on the power
9. Release the keys when the message “Verifying the EEROM” will be shown. The transmitter is
confirming that the new firmware is valid.
10. After the EEROM has been read and confirmed this message will be shown:
Upgrade Firmware?

13. TROUBLESHOOTING
The Teledyne Analytical Instruments oxygen transmitter has proved an extremely reliable instrument.
The trouble shooting guide here is based on an analysis of the potential problem that may occur after
many years of operation in the field. A current list of problems and solutions can be found on the
13.1 FIRST APPROACH
The probe will not heat up.
Turn the power off, remove and check 2 x 20mm glass fuses. If either of them is blown, check the
probe heater resistance between the two white wires that come from the probe. It should be 110 +/‐
15 ohms, and both wires should be open circuit to earth. If not, replace the probe.
Is the ‘B’ shown on the bottom left hand corner of the display? If not, check that the burner is enabled
with either a link between terminals 10&11, BURNER INPUT, or is enabled with a connection to a
voltage‐free contact from the main fuel valve to these terminals.
The display is blank and there is no backlight on.
Measure the power supply voltages at the test points labeled COMM and +5v at the right hand side of
the main PCB 1732‐1. It should be 5 +/‐ 0.15v.
Turn off the power and remove the main shield. Check that the plug‐in fuse FS1 has not blown. It
should only be replaced with a 1A, 250v fuse if it has blown.
Is the mains power being supplied to terminals 36&37 and is it between 100 and 240VAC? If may be
necessary to replace the switch mode power supply, PS5, APC‐5S.
An ‘ADC Calibration Fail’ alarm has occurred.
Turn the transmitter off and remove the main shield. Turn the transmitter back on and measure the
voltages on the ‘Acom’ test points. With the negative lead on the centre terminal the other 2
terminals should measure 12 +/‐0.3v. If not, replace the small DC‐DC converter PS4.
An ‘Output 1 (2) Failure’ alarm has occurred.
Turn the transmitter off and remove the main shield. Turn the transmitter back on and measure the
voltages on the ‘D1com’ test points. With the negative lead on the centre terminal the other 2
terminals should measure 12 +/‐0.3v. If not, replace the small DC‐DC converter PS4.
A ‘Heater 1 (2) Failure’ alarm has occurred.
The software has found that the SSR4 has failed. If only one probe is being used and you need to gets
the transmitter back working quickly, use the CALIBRATION menu function 18, Heater SSR Select, to
change the heater output terminals. See chapter 8.2.8, Heater SSR fault correction.
A ‘BBRAM Fail’ alarm has occurred
Replace the BBRAM, MEM1 on the 1732‐1 main PCB.
13.2 DETAILED FAULT ANALYSIS
The 9060Z transmitter has a diagnostics mode built into the software. This mode allows detailed
analysis of the hardware of the transmitter, but does require a level of competence in electronics.
The diagnostics mode is selectable by turning the ‘Diagnostics’ DIP switch to ON and then turn on the
power. There is a separate Diagnostics Mode Manual available that describes its use. Ask Teledyne
Analytical Instruments for more details.

14. MAINTENANCE
14.1 TRANSMITTER MAINTENANCE
The 9060Z transmitter has several hardware checking systems that confirm the correct operation of
the transmitter and raise an alarm if there is a fault detected. Because of this system, the transmitter
only requires periodic maintenance. Teledyne Analytical Instruments recommends an annual check of
the transmitter.
The annual check should include the following items –
1. Measure and record the reference voltages, and check that the correct voltages are set in the
calibration menu
2. Check that the reference air flow from the port on the bottom of the transmitter case is between
100 and 300cc/m
3. Check for contamination and potential blockage of the reference air filter that is mounted on the
bottom of the transmitter case
4. If an external burner interlock has been connected (terminals 10 & 11), check that if one of the
wires is disconnected the probe heater is disabled (9060H probes only)
5. Check the integrity of the cable. Particularly check the main power supply cable and the probe
cable for any damage.
6. Check the integrity of the earth connections in the transmitter
14.2 CLEANING
The 9060Z transmitter is made in an IP65 / IP54 rated diecast case. It is painted with a tough ripple
finish power coating to maintain a clean look. However, if it is necessary to clean the case use either a
warm soapy water solution or an isopropyl alcohol.
A build up of dust on or around the transmitter should be removed before the cabinet door is opened.
If there is a buildup of dust inside the cabinet check the door o‐ring seal for damage and replace it if
necessary.
Take care when wiping the display window to avoid scratching the surface.
If the filters of the probe (if fitted) become blocked, use an ultrasonic cleaner with a few drops of
household detergent. If the filters cannot be cleaned this way replace the sintered filters.
The filter in the base of the analyzer may become blocked if the analyzer is operating in a dusty
environment. It is available as a field replacement item.

All holding register addresses contain a single 16 bit value, however some variables span multiple
holding registers to yield a single 32 bit variable.
When reading register values be aware that the byte order of data within registers may differ from
that of the target system.
Modbus Protocol
The modbus over serial line protocol defines a messaging system for master/slave communications.
Only one master device may be connected to any network with one or several slave nodes.
In unicast mode, the master initiates communication with a specific slave node by sending a request
message. The slave processes the request and returns a reply message containing the requested
information or a confirmation that the request was fulfilled.
Modbus requests are transmitted as a formed request frame with a CRC for data integrity checking.
The frame for each request and reply type will vary somewhat, but will always have the basic
structure described below:
1 byte
1 byte
up to 255 bytes
2 bytes
slave address
function code
data
checksum
Internal Representation of Dates & Alarm Status
