Conductivity High Alarm
This error message indicates the conductivity reading exceeds the user-programmed maximum
allowable value.
Possible Causes Corrective Actions
Programmed value is too close to Go to the Conductivity Input Page and make
conductivity set point. sure that the high alarm limit is set at least 5%
above the set point.
Control direction is set incorrectly. Go to the Relay Output Page and check the
setting for the control direction.
Faulty control device. Repair or replace the control device.
Fuse blown. Replace fuse (F2 or F3).
Faulty control device wiring. Correct wiring.
Faulty relay. Replace the relay interface board.
Conductivity Low Alarm
This error message indicates the conductivity reading is below the user-programmed minimum
allowable value.
Possible Causes Corrective Actions
Dirty conductivity electrode. Clean and calibrate the conductivity sensor as
described in Section 7.2 above. If calibration
fails, see troubleshooting for Conductivity
Calibration Failure above.
Faulty conductivity electrode wiring. Correct wiring.
Faulty conductivity electrode. Replace sensor.
Conductivity electrode is dry. Adjust sensor location below the minimum
water level.
No sample flow. Restore flow of sample
Faulty control device. Repair or replace the control device (valve).
Fuse blown. Replace fuse (F2 or F3).
Faulty control device wiring. Correct wiring.
Faulty relay. Replace the relay interface board.
Intermittent Sampling, sampling too frequently Increase the Interval Time.
