3. PRINCIPLE OF OPERATION
The detection of ozone molecules is based on absorption of 254 nm UV light due to an
internal electronic resonance of the O molecule. The M465M uses a mercury lamp
3
constructed so that a large majority of the light emitted is at the 254nm wavelength. Light
from the lamp shines through an absorption cell through which the sample gas is passed.
The ratio of the intensity of light passing through the absorption cell and the intensity of
light measured by a reference detector forms a ratio I/Io. This ratio forms the basis for
the calculation of the ozone concentration.
The Beer-Lambert equation, shown below, calculates the concentration of ozone from the
ratio of light intensities.

o
CO
n
3
L 273
Where:
I = Intensity of light passed through the sample
Io = Intensity of light through sample free of ozone
= absorption coefficient
L = path length
CO = concentration of ozone in parts per million
3
= sample temperature in Kelvin
= pressure in pounds per square inch (absolute)
As can be seen the concentration of ozone depends on more than the intensity ratio.
Temperature and pressure influence the density of the sample. The density changes the
number of ozone molecules in the absorption path which impacts the amount of light
removed from the light beam. These effects are addressed by directly measuring
temperature and pressure and including their actual values in the calculation. The
absorption coefficient is a number that reflects the inherent ability of ozone to absorb 254
-1
-1
nm light. Most current measurements place this value at 308 cm atm at STP. The
value of this number reflects the fact that ozone is a very efficient absorber of UV
radiation which is why stratospheric ozone protects the life forms lower in the
atmosphere from the harmful effects from solar UV radiation. Lastly, the absorption path
P/N 06160D DCN6409 Teledyne API Model 465M O3 Monitor Instruction Manual - Page 13
Download from Www.Somanuals.com. All Manuals Search And Download.
length determines how many molecules are present in the column of gas in the absorption
tube.
The intensity of light is converted into a voltage by the detector/preamp module. The
voltage is converted into a number by a high resolution A/D (analog-to-digital) converter.
The digitized signal, along with the other variables, is used by the CPU to compute the
concentration using the above formula.

4.3. AC Power Connection (for Monitors in
NEMA 4X Enclosures)
CAUTION
Disconnect power to the AC mains before making or removing
any electrical connections to the M465M.
CAUTION
A proper earth ground connection must be made to the
receptacle labeled “Earth Ground” on the 3 pin AC connector.
Failure to do so may result in a shock hazard and malfunction
of the monitor
1. Install a ½” conduit fitting for routing the electrical wiring into the monitor through
the hole provided in the bottom face of the NEMA enclosure; an appropriate sealed
conduit connector should be used.

Download from Www.Somanuals.com. All Manuals Search And Download.
3. For the NEMA configuration, the electrical connection must be hard-wired to
the 3-pin connector on the mainboard labeled J23. AC power connection to the
monitor should be made with 12-14 AWG stranded copper wire, connected to the
monitor as follows:
a. Earth Ground (green): Connect the earth ground wire to the screw terminal lug on
the chassis as shown in the Figure below. Do not connect
the earth ground wire directly to the PCB connector on the
mainboard PCB.
b. Line (Black):
Connect the Line wire to the connector on the mainboard
PCB labeled “Line”.
c. Neutral (White):
Connect the Neutral wire to the connector on the
mainboard PCB labeled “Neutral”.
Figure 4-2. NEMA AC Power Connection to Monitor

The M465M front panel provides a number of functions in addition to displaying the
current ozone concentration being measured Figure 7-1 below shows the display and
keypad portion of the front panel.
Figure 7-1: Front Panel Display
7.1.1. Ozone Concentration Display
The 4-character LED display in the center of the front panel normally shows the current
ozone concentration being measured by the M465M. While displaying concentration,
one of the unit-of-measure indicators (i.e., WT%, PPM) should be backlit, indicating the
current measurement units. If none of these indicators are backlit, then the display is in
Menu mode or Startup mode and is not displaying the concentration. If the display is in
Menu mode, the display can be returned to Concentration mode by repeatedly pressing
the CFG button until one of the unit-of-measure indicators is lit. Note that even when the
display is in Menu mode, normal measurement operation will continue in the
background.

7.2.3.4. Zero Calibration
The zero calibration allows the instrument to calibrate it’s internal ozone offset factor.
This should only be done with a source of zero air connected to the “Sample In” port of
the M465M. Allow the instrument to stabilize on the zero air source before attempting to
zero. This normally takes 10-15 minutes.
If the zero calibration is enabled, the internal ozone offset factor will automatically be
reported as zero every 6 minutes. If the zero calibration is disabled, then manual
calibration is necessary based on the customer’s applications. For normal applications,
the zero calibration is not necessary.
When entering the Zero Calibration menu, the prompt “ENT TO CAL” appears on the
display. Simply confirm the calibration by pressing the ENT button to perform the
calibration (to abort the calibration, press and hold the CFG button to return to the
previous menu level.) After pressing ENT, the instrument will automatically exit the
menu mode and return to Concentration mode. The concentration reading should quickly
go to zero.

Download from Www.Somanuals.com. All Manuals Search And Download.
NOTE
While measuring zero air, a certain amount of noise or
“dithering” of the concentration about the zero point will occur
and is normal. This noise is typically 1-3 PPM in magnitude.
7.2.3.5. Span Calibration
The Span Calibration also allows the instrument to calibrate its internal ozone offset
factor. The Span Calibration however, is done with some controlled concentration gas
connected to the “Sample In” port of the M465M. It is recommended that a span gas is
concentrated to around 80% of the operating range. Set the SPAN VALUE to the
measured concentration of your calibration gas. This normally takes 10-15 minutes.
NOTE
A Span Calibration should only be performed with a stable
source of Ozone and a reference monitor measuring the same gas
supply.
If you are unsure regarding the suitability of a particular source
of calibration gas, contact Customer Service at Teledyne API for
assistance (see Section 12.)
enter the Span Target concentration (the actual concentration of ozone being supplied to
the monitor) and press ENT. The display will next show a confirmation menu, ENT TO
SPAN. Press ENT to perform the Span Calibration, or CFG to abort back to the start. If
the calibration is successful, the display will return to the concentration menu and the
monitor reading should change adjust to read very close to the target value. If the
calibration cannot be performed, an OUT OF RANGE error will be displayed. Press
ENT to confirm and the display will return to the start of the Span Cal menu.
If the OUT OF RANGE error occurs, it means the Span Cal cannot be performed
because it would result in an out of range slope value for the monitor. This means that
either the sensor in the monitor is malfunctioning, causing improper readings, or the
actual ozone concentration being supplied to the monitor is different than the target value
being entered.

8.5. Ethernet Configuration
Ethernet is commonly used for factory automation busses with a computer or PLC acting
as a master. The communications protocol used for the Ethernet configuration is
MODBUS TCP/IP. For details on the MODBUS TCP/IP specification, please see
A Windows software application, DeviceInstaller, is available for configuring the
Ethernet module used in the M465M. This application is available for download here:
8.5.1. Hardware Setup for Configuring the Ethernet
Module
To make the first-time configuration of the Ethernet module as easy as possible, the
module comes from the factory with DHCP enabled. The M465M can simply be plugged
into a network with a DHCP server and an IP Address should be automatically assigned
to, and stored in, the device.
A simple network can easily be constructed for this purpose by using a small broadband
router commonly used for home networks. The M465M and a PC can then be connected
to the router and the router’s DHCP server will assign IP Addresses to both the PC and
the M465M, enabling them to communicate.
8.5.2. Verifying Network Hardware Connection
With the M465M connected to a network and powered up, check the status of the two
LEDs on the Ethernet connector on the rear panel. The left-hand LED should be lit,
either amber or green indicating link status and the right-hand led should blink
the status LED’s.
If neither of the LED’s are lit, then the Ethernet module may not be powered up or the
instrument may not be connected to a valid network. Check the COM port configuration

9.10. Boot Loader Operation
The main function of a boot loader is to load or update the firmware to the
microcontroller on the Printed Circuit Board (PCB) of an instrument. There are two
types of boot loader setup: hardware and software, described in the following sections.
NOTE
When an external MODBUS host device is attempting to
communicate with the instrument over the serial or Ethernet port
while the instrument is starting up, the instrument may halt. In
order to prevent the problem from occurring, ensure that there are
no devices attempting communication with the instrument during
start-up. Once the sign-on message is displayed on the front
panel, it is safe to begin communications.

10.2.1. Sensor OK
The Sensor OK LED indicates the status of the O3 sensor module in the monitor. The
normal state of this LED (or Status Output) is On. If this LED remains off after the
normal warm-up period, then a failure has occurred and the monitor should be
removed from service and repaired.
The most common cause of this warning is a failure of the UV Lamp. A UV Lamp
adjusted to meet the specified values, then a UV Lamp Replacement should be
performed (See Section 9.5.)
10.2.2. Invalid Reading
The Invalid Reading LED indicates that the instrument is reading a value that cannot
be represented properly on the analog output. Since the analog output is limited to 0-
5V (or 4-20mA,) it cannot properly represent negative values, or values in excess of
the full-scale range.
If the monitor is consistently reading negative values, then a zero calibration should
be performed, see Section 7.2.3.4.
If the monitor is consistently reading values in excess of the full-scale range, then the
range value.
10.2.3. Check Lamp
The Check Lamp LED indicates that the UV Lamp intensity has dropped below
next convenient opportunity. Note that this is a non-critical warning, unless it is also
accompanied by Sensor OK LED turning off, then the instrument does not need to be
removed from service at this time. If the UV Lamp intensity drops below 125mV,
then the Sensor OK LED will also turn off, indicating that the monitor must be
immediately serviced or taken off-line.
10.2.4. Pneumatic Error
The Pneumatic Error LED indicates that one of the pneumatic parameters, flow or
pressure, has gone outside of normal ranges. Note that this is a non-critical warning.
Unless it is also accompanied by Sensor OK LED turning off, the instrument does not
need to be removed from service at this time.
The first step in troubleshooting a Pneumatic Error is determining which parameter
has caused the warning. At the monitor front panel, navigate to the VIEW menu (See

10.2.4.1. Pressure Too High
The monitor inlet is being pressurized. The monitor inlet should be allowed to
sample gas at ambient pressure. Disconnect all sample lines from the monitor and
read the pressure again. If the value then drops to within the acceptable range,
then one of the sample lines is at elevated pressure.
If the inlet is being pressurized, then the design of the sample system should be
reviewed and corrected.
10.2.4.2. Pressure Too Low
Something may be restricting the flow through the monitor, causing the sample
pump to pull a vacuum on the sensor module. First, unplug the sample pump
power plug on the Mainboard PCA and observe the pressure reading. If the
pressure reading is still too low, then likely there is a problem with the pressure
sensor on the Sensor Module and the Sensor Module should be replaced. Next
reconnect the pump and disconnect all sample lines from the monitor and see if
the pressure increases to normal levels. If it does, then the problem is somewhere
in the sampling system external to the monitor. If the pressure is still below the
limit with the sample lines removed, then there is a restriction in the pneumatics
of the monitor upstream of the sensor assembly. The most likely cause is a
plugged particulate filter. Disconnect the outlet fitting on the sample filter and
observe the pressure. If it returns to normal levels then the restriction is in the
particulate filter or inlet manifold assembly (multi-stream configurations only.)
Replace particulate filter per Section 9.3.
