STANDARD VS. WINDOW MODE
The terms “Standard” and “Window” describe two methods for
setting up the Smart-SwitchTM to monitor pressure.
Standard Mode
In Standard Mode, illustrated in Figure 8, the SP1i (or SP2i) set
point actuates when the pressure being monitored goes above the
set value. At this point, the Smart-SwitchTM might turn off
whatever electrical power is being applied to a pump, for
example, which is increasing or maintaining the pressure. The
switch de-actuates, or resets, when the pressure drops below the
preset decreasing set point (SP1d or SP2d). At this time, the
electrical power to the pump would be turned back on.

Deadband
The deadband is the separation between the increasing set point
and the decreasing set point, as shown in Figure 8. The deadband
can be anywhere from 1% to 99% of Full-Scale Output (F.S.O.).
In the case above where the Smart-SwitchTM is controlling a
pump, a wider deadband reduces the frequency at which the pump
cycles on and off.
Window Mode
This mode is useful when you want to maintain pressure within a
certain range, and want to be notified when pressure either goes
above or falls below that range. In Window Mode, the Smart-
Switch® starts out actuated, then deactuates when it reaches its
lower set-point (SP1d or SP2d). As pressure continues to
increase, the switch actuates again when it reaches the upper
set-point (SP1i or SP2i). This range between the lower and upper
set-points is the "window". When pressure decreases, the
sequence reverses, with a deadband of 1% of F.S.O. at each of the
set-points. See Figure 9.
In this mode, the Smart SwitchTM might be wired to, say, an alarm
bell, which would sound if the pressure either rose above SP1i or
fell below SP1d.

Scalable Readout: Option Q
With this option installed, you can change the scale factor of
the display to read in different units of pressure, or in
arbitrary numbers that you choose.
If your system is set up with pressures in bars, for example,
you might want the Smart-SwitchTM display to show bars
instead of psig.
The r-Hi, r-Lo and .Loc menu functions allow you to scale
the readout to your preference. In the following example,
millibars are used:
You have a scalable 801P5 with the 15psig sensor. You
want to represent the pressure in millibars. The standard
conversion unit is 1 psi = 68.95 millibars.
You want to read zero for zero pressure, therefore,
r-Lo = 0.
Full-scale output pressure for the 801P5 for this example
is 15 psig. So, r-Hi = 68.95 x 15 = 1034.25 millibars,
which rounds to 1034. Therefore r-Hi should be set to
1034.
The unit now reads from 0 to 1034 millibars for 0 to
15 psig pressure. The accuracy is ± 2 millibars, which is
± 0.2% of 1034.
You can use the scalable readout to set the display to read
whatever units are most familiar to you, or arbitrary numbers
such as 0 to 10. With the 4-digit display, you can use
positive numbers to 9999, and negative numbers to -999 (for
fewer digits, use leading zeros).

To change the (r-Lo)and (r-Hi):
1. Press the [MENU] key and use the [UP/DOWN ARROW]
keys to move through the menu selections to r-Lo.
2. Press [SELECT]. The furthest right digit will blink.
3. Change the digit’s value with the [UP/DOWN ARROW] keys.
4. When the value is correct, press the [SELECT] key to move to
the next digit and repeat step 3. Repeat for each digit until
you have the correct value for r-Lo.
5. Use the [STORE] key to temporarily save the changes and
return to the main menu.
6. Press [RUN]and then [SELECT] to permanently save the
setting and return to On-Line operation.
7. Repeat steps 1 through 6 for r-Hi. The setting should be at
least 2 display counts higher than r-Lo.
Decimal Location (.Loc)
You can change the location of the decimal point, thereby
changing the scale of the display, by using this function.
After .Loc displays, press [SELECT] to move the location
one digit left. When the correct location has been reached,
press [STORE] to temporarily save your setting.
When the decimal point is in the far right location, no decimal is
displayed during operation.

Pressure Calibration (PCAL)
You can do a field pressure calibration using this function.
After PCAL is displayed, use the [SELECT] key to enter the
submenu. LO-P will be displayed for one second, and then
the switch’s interpretation of the actual pressure will be
displayed. Apply 0.0 psig to the unit. Use the [UP/DOWN
ARROW] keys to adjust the pressure display to zero psig.
Press the [STORE] key. The display will show HI-P for one
second, followed by the switch’s interpretation of the actual
pressure applied. Apply Full- Scale pressure to the unit. Use
the [UP/DOWN ARROW] keys to set the display equal to
Full- Scale pressure. Press the [STORE] key to return to the
main menu.
A pressure source is required for this operation. In addition,
calibration equipment used must have an accuracy of at least
± 0.02% F.S.O. of the switch being calibrated.
NOTE
NOTE
If re-calibration results in zero or Full-Scale readings that have
shifted by 4% F.S.O. or more from the factory calibration, an
error code of EROR will be displayed.
Reset (rSET)
This command resets the Smart-SwitchTM to factory default
settings. After rSET appears, press [SELECT], [STORE],
[RUN] and [SELECT] to reset the unit to factory defaults.
These are as follows:
r-Hi returns to factory F.S.O.
r-Lo is set to zero
Spli is set to 60% of the full range.
SPld is set to 40% of the full range.
SP2i is set to 70% of the full range.

ANALOG OPTION
The analog option (V option) for the 801P5 allows you to equate
pressure with electrical current. If your Smart-SwitchTM includes
this option, the 4-20 mA output can be scaled; see page 27.
ANALOG OPTION WIRING
The 4-20 mA output connections are provided by the two pin
connector located on the top right of the unit:
Pin A is the + (positive) output
Pin B is the – (negative) output
The 801P5 generates its own loop power and it can operate with a
load resistance of 600 ohms maximum.

4-20 MILLIAMPERE OUTPUT CALIBRATION (4CAL)
The 801P5 is factory calibrated to generate 4 mA when the
pressure sensor is at 0 psig, and 20 mA when rated pressure is
applied. Tolerances in your signal conditioning equipment may
result in readings varying from these values, so you can calibrate
the 4-20 mA output as follows to correct these readings.
1. Connect a calibrated milliammeter to the 4-20 mA output.
2. Press [MENU], then press the [UP/DOWN ARROW] key
until 4CAL is displayed.
3. Press [SELECT]. The display will show LO-C.
4. While reading the milliammeter, use the [UP/DOWN
ARROW] keys to adjust the output to 4 milliamperes.
5. Press the [STORE] key. The display will read HI-C.
6. Use the [UP/DOWN ARROW] keys to adjust the output to
20 mA, then press the [STORE] key to temporarily save the
calibration data and return to the main menu.
7. Press [RUN] and [SELECT] to save the changes and return
online.
If the 0 or Full Scale output has shifted by 4% of F.S.O. or more
NOTE
from the factory calibration, EROR will be displayed.

4-20 MILLIAMPERE OUTPUT SCALING
The 4-20 mA output is scaleable, allowing 4 mA to represent any
pressure between 0% and 66% F.S.O., and 20 mA to represent
any pressure between 33% and 100%F.S.O. This feature is helpful
in systems where the normal operating pressure falls within the
pressure range of the unit. For example, let’s assume that the
Smart-SwitchTM has a pressure range of 0 to 100 PSIG, and the
process that it is monitoring operates between 20 and 80 PSIG.
The equipment that is monitoring the 4-20 mA output expects 4
mA to represent 20 PSIG, and 20 mA to represent 80 PSIG. Using
the following instructions, by setting SCLO to 20 PSIG and SCHI
to 80 PSIG, these conditions will be met.
Scale Low (SCLO)
To set the pressure at which the output equals 4 mA, press the
[UP/DOWN ARROW] keys until SCLO is displayed. Press
[SELECT] to enter the submenu. Use the [SELECT] key to move
from digit to digit and use the [UP/DOWN ARROW] keys to
adjust each digit. Once you have set the pressure, press [STORE]
to save your setting. The range of adjustment for this function is
zero psig to 66% of F.S.O.
The difference between the SCLO setting and the SCHI setting
NOTE
must be at least 33% of F.S.O.
Scale High (SCHI)
To adjust the pressure, at which the output equals 20 mA, use the
[UP/DOWN ARROW] keys until SCHI is displayed. Use the
[SELECT] key to enter the submenu. Use the [SELECT] key to
move from digit to digit and use the [UP/DOWN ARROW] keys
to adjust each digit. Once you have set the pressure that should
equal 20 mA output, press the [STORE] key to save your setting.
The range of adjustment for this function is 33% F.S.O to 100%
of F.S.O.
The difference between the SCLO setting and the SCHI setting
NOTE
must be at least 33% of F.S.O.

It is unlikely that you’ll have any problems with the
Smart-SwitchTM. However, just in case, this chapter contains
information to help diagnose and correct any error messages you
may see.
ERROR MESSAGES
Below are error messages that you may see during operation or
programming, along with brief descriptions of how to correct
them. If you see an error that is not listed here, contact Neo-Dyn
Customer Service. The contact information is located in
Chapter 1.
Display Shows ---0
The [MENU] key has been pressed and the unit has a password
other than 0000. Use the [UP/DOWN ARROW] keys to set the
first digit at the correct value. Use the [SELECT] key to move to
the next digit. Repeat this process until the display shows the
correct password. Press the [STORE] key to enter the
programming menu.

Display Shows EROR
This message might appear while programming the 801P5
Smart-SwitchTM. The meaning depends on what is being
programmed. Following are the possible causes and solutions.
Incorrect password entered
You have entered an incorrect password. Re-enter the
correct password. If you have lost or forgotten the password,
contact Neo-Dyn Customer Service for assistance.
Incompatible switch set points.
You have entered incompatible set points. Switch 1 and
Switch 2 are independent of each other; however, the
following rules apply to each switch:
The increasing set point must be at or below the Full Scale
Output (F.S.O.) value; it cannot be less than 2% of F.S.O.,
and it must be at least 1% of F.S.O. above the decreasing set point.
The decreasing set point must be no lower than 1% of
F.S.O.; it can be no higher than 99% of F.S.O.; and it must
be at least 1% of F.S.O. below the increasing set point.
The minimum deadband is 1% of F.S.O.
Re-enter the set points to conform to the requirements.

Pressure Calibration (PCAL) or Analog Output
Calibration (4Cal) is incorrect.
If you change the value for pressure or analog output
calibration more than 4% of the F.S.O. from the original
factory values, this error occurs. Contact Neo-Dyn Customer
Service for assistance.
If the power to the unit is turned off and then back on, the unit
will function using the new values. However, this is not
recommended, as a calibration error this large indicates imminent
component failure.
NOTE
Display shows HHHH
This indicates that the unit is online and monitoring pressure, but
the pressure is at or greater than 110% of F.S.O. When the
pressure returns to less than 110% of F.S.O., the display will
return to its normal pressure display.
Display shows LLLL
This indicates that the unit is online and monitoring pressure, but
the pressure is less than 4% of the F.S.O. below zero psig (pulling
a vacuum). When the pressure returns to greater than 4% of the
F.S.O. below zero psig, the display will return to its normal
pressure display.
An unlikely possibility is that the pressure transducer's connector
has been dislodged from the internal circuit card. Check to insure
that the transducer connector is indeed connected. Contact
Neo-Dyn Customer Service for assistance.

Display alternates between OPEN and LOOP and the
pressure reading
The OPEN LOOP message is displayed with the V option
(4-20 mA analog output) in the following circumstances:
The analog loop is turned on, but nothing is connected to the
analog output connector. In this case, press the [MENU] key
to enter the programming mode. Use the [UP/DOWN
ARROW] keys to set this option to OFF. Press the [STORE]
key to temporarily save the change. Press the [RUN] key,
followed by the [SELECT] key to save the change
permanently and return on-line.
The analog loop is turned on and connected, but the
connection has been broken. In this case, repair the broken
connection, or turn the loop off using the method described
in the previous paragraph.
Load resistance exceeds 600 ohms. In this case, reduce the
resistance.
Display is blank
Press the [S1 INCR] key. If the display illuminates and displays
the increasing set point for Switch 1, then the Disp display update
option has been set to OFF.
If the display does not react, there has been an internal component
failure. Contact Neo-Dyn Customer Service for assistance.
Display shows E-95
This code indicates that the internal manufacturing data, which is
saved in the nonvolatile RAM, has become corrupt.
Power down the unit and then turn the power back on. If the unit
continues to show E-95, contact Neo-Dyn Customer Service for
assistance.

Display shows E-96
This code indicates an internal A/D reading that is out of its
allowable tolerance. Although this can indicate an internal
component failure, the most common cause of this error is
vacuum applied to the pressure port of the unit. If the cause is
vacuum, once the pressure returns to near zero, the unit will return
to monitoring and controlling. If the cause is internal component
failure, contact Neo-Dyn Customer Service for assistance.
Display shows E-97
This error indicates that the internal user data, saved in the
nonvolatile RAM, has become corrupt. Press the [SELECT] key to
cause the unit to reboot. If the unit continues to show E-97,
contact Neo-Dyn Customer Service for assistance.
