TEMP ERROR
This error condition will stop conductivity control. It indicates that the temperature signal from the conductivity sensor is no longer valid. This
prevents
controlling based upon a false conductivity reading.
Possible Cause
Corrective Action
Improper wiring of sensor to controller.
Correct wiring
Temperature input is set to the incorrect element
Reprogram to RTD 1000 Ohm Element
Faulty sensor.
Replace sensor.
SENSOR FAULT
This error condition will stop conductivity control. It indicates that the conductivity signal from the sensor is no longer valid. This prevents
controlling based upon a false conductivity reading.
Possible Cause
Corrective Action
Sensor wire disconnected.
Reconnect
Sensor wires shorted
Check and disconnect short
Faulty sensor.
Replace sensor.
Faulty controller.
Replace or repair controller (Contact factory)
BATTERY POWER LOW
This alarm indicates that the battery which holds the date and time in memory is below 2.4 VDC
Possible Cause
Corrective Action
Faulty Battery
Replace Battery
CONTROLLER, POWER, SENSOR or DISPLAY BOARD VARIANT
This alarm occurs if the type of board detected is not valid.
Possible Cause
Corrective Action
Poor ribbon cable connection
Reseat ribbon cable
Faulty ribbon cable
Replace ribbon cable
Faulty board
Replace board listed in the error message
Incompatible software version
Install correct software version (Contact factory)
CONDUCTIVITY READOUT DOES NOT CHANGE
Possible Cause
Corrective Action
Readout is stuck at or near zero:
Dry Sensor
Sensor is disconnected
Check for water flow through sample loop
Check sensor wiring
Readout is stuck at another number:
Dirty sensor
Stagnant sample
Faulty sensor
Clean sensor (Refer to Section 6.1)
Check system for proper flow
Replace sensor
