Temperature calibration, high/low alarm menus missing from Sensor Input page
The controller not detecting the temperature sensor at power up causes this problem.
Possible Causes
Corrective Actions
The temperature sensor is not connected.
Connect the temperature sensor and
turn power on.
Faulty temperature sensor.
Measure the temperature signal using an
ohmmeter between the green wire and the
WHT/GRN wire as close to the sensor as
possible with the wires disconnected from
the terminal strip. If the reading is infinite
ohms, replace the sensor.
Sensor input is selected to be an ORP type
This is normal. ORP inputs do not use automatic
temperature
compensation.
Link to 4-20 mA Output page does not appear
The controller not detecting any 4-20 mA output boards at power up causes this problem.
Possible Causes
Corrective Actions
No 4-20 mA output boards are installed.
Install one or more 4-20 mA output boards
and turn power on.
Poor connection of the 4-20 mA output
Remove the option board and inspect both
board.
mating connectors for corrosion or damage
Reinstall the option board on turn power on.
Link to Level page does not appear
The controller not detecting either a digital input board or an analog input board at power up
causes this problem.
Possible Causes
Corrective Actions
No digital or analog input board is installed. Install the desired option board and turn
power
on.
Poor connection of the option board.
Remove the option board and inspect both
mating connectors for corrosion or damage
Reinstall the option board on turn power on.
Link to Digital Inputs page does not appear
The controller not detecting a digital input board at power up causes this problem.
Possible Causes
Corrective Actions
No digital input board is installed.
Install the digital input option board and
turn power on.
Poor connection of the option board.
Remove the option board and inspect both
mating connectors for corrosion or damage
Reinstall the option board on turn power on.
