8. Simultaneously press and release “SEL” and “UP” keys; then adjust
setpoint signal to lower input value, e.g., 4 mA. Voltage reading
should be less than 1 volt. Quick tap “SEL” to lock in value.
9. Quick tap “DN” key. Display will flash “SEtU” and a value.
10. Simultaneously press and release the “SEL” and “UP” keys; then
adjust setpoint signal to higher input value, e.g., 20 mA. The voltage
reading should be between 3.800 and 5.000 volts. Quick tap “SeL”
to lock in value.
11. Quick tap “DN” key. Display will flash between “PoC” and a number
between 0 and 5 volts.
12. Simultaneously press and release the “SEL” and “UP” keys. Using
the “UP” or “DN” key, adjust so shaft is full clockwise. The display
should read between .200 and .400 volts. If not, rotate feedback
potentiometer face gear with your fingers. It is a friction fit. Quick
tap “SEL” to lock in reading.
13. Quick tap “DN” key. Display will flash between PoCC and the feed-
back voltage value.
14. Simultaneously press and release the “SEL” and “UP” keys. Using
the “UP” or “DN” key, adjust so shaft is full counterclockwise. The
display should read greater than 3.000 volts. If not, recheck “PoC”
and if correct, contact factory. Quick tap “SEL” to lock in reading.
15. Calibrating Analog Process #1 Lower Input Signal
This procedure is followed only if an analog process module is used.
Quick tap “DN” to select the lower input parameter “Pr1L”. Simul-
taneously press and release “SEL” and “UP”, then adjust process
input signal to lower value of 4.0 mA. The voltage on the display
should be less than 1 volt. Quick tap “SEL” to lock in this value.
16. Calibrating Analog Process #1 Upper Input Signal
This procedure is followed only if an analog process module is used.
Quick tap “DN” to select the upper input parameter “Pr1U”. Simul-
taneously press and release “SEL” and “UP”, then adjust process
input signal to upper value of 20 mA. The voltage on the display
should be greater than 3.000 volts. Quick tap “SEL” to lock in value.
17. Calibrating Single Channel RTD Process Module
This procedure is followed only if a single channel RTD process
module is used. This step calibrates both the lower and upper
process limits.
Quick tap “DN” to select either the “Pr1L” or “Pr1U” input param-
eter. Simultaneously press and release “SEL” and “UP” to begin
calibrating the parameter.
a. Attach a calibrated resistance type RTD siumulator to the
process input.
b. Simultaneously press and release “SEL” and “UP” keys to
change the temperature units. When “SEL” and “UP” are
pressed, the units will begin flashing. Pressing the “UP” or
“DN” key will change the units between degrees Fahrenheit
and Celsius. When the correct units are flashing, quick tap
“SEL” to lock in the selection.
c. Simultaneoulsy press and release “SEL” and “UP” keys to
change the temperature range upper limit. When “SEL” and
“UP” are pressed, the upper limit will begin flashing. Pressing
the “UP” or “DN” keys will change the upper limit to another
value. When the correct range value is flashing, quick tap
“SEL” to lock in the selection. The upper limit of the range will
not be able to be set to a value that is less than 50°C (100°F)
above the lower limit, i.e., there must be at least 50°C (100°F)
between limits.
d. Simultaneously press and release “SEL” and “UP” keys to
enter the voltage display mode. Simulate the upper limit
temperature, and adjust the span potentiometer on the module
such that the voltage is between 4.200 and 4.700 volts on the
display. Change the RTD simulator to simulate the lower limit
temperature, and adjust the zero potentiometer on the module
such that the voltage is between 0.200 and 0.800 volts. Repeat
the above process until the upper and lower voltages are within
the stated limits. When completed, be sure that the simulator
is simulating the upper limit temperature. Quick tap the “SEL”
key to lock in the upper limit voltage.
e. Simultaneously press and release “SEL” and “UP” keys to
change the temperature range lower limit. When “SEL” and
“UP” are pressed, the lower limit will begin flashing. Pressing
the “UP” or “DN” keys will change the lower limit to another
value. When the correct range value is flashing, quick tap
“SEL” to lock in the selection. The lower limit of the range
will not be able to be set to a value that is greater than 50°C
(100°F) below the upper limit, i.e., there must be at least 50°C
(100°F) between limits.
f. Simultaneously press and release “SEL” and “UP” keys to
enter the voltage display mode. Enter the lower limit tempera-
ture (either 0°C or 32°F) in the simulator. The resulting voltage
reading will be displayed.
NOTE: Do not adjust either the zero or span potentiometers in
this step.
Quick tap the “SEL” key to lock in the lower limit voltage. Note
that zero adjustments are made in the procedure for the upper
limit. This step is just used to record the lower limit voltage.
18. Calibrating Thermocouple Process Module
This procedure is followed only if a thermocouple process module is
used. This step calibrates both the lower and upper process limits.
Quick tap “DN” to select either the “Pr1L” or “Pr1U” input param-
eter. Simultaneously press and release “SEL” and “UP” to begin
calibrating the parameter.
a. Attach a calibrated thermocouple simulator to the process input.
NOTE: For greatest accuracy, the thermocouple simulator
should be connected to the controller input module; and the
simulator and the controller board should be turned on and
