Remedy

Check CUE local HMI for fault description.

Check pre-fuses and circuit breakers.

Check all external modules connected via GENIbus.

Check pump, valves and pipes for blockages.

Check voltages between phases, pre-fuses and circuit

breakers.

Check phase sequence.

Water-in-oil content has passed threshold. Lower shaft-

seal and oil needs replacement.

User-defined service interval has been reached.

Arrange for preventive maintenance.

Check cellular network connection. Check if SCADA

phone number is correct. Check status of external

SCADA system.

Check fault locally on CUE drive.

Check status of dosing pump. Perform calibration

of dosing pump.

Test trip activated on MP 204.

Check setting. Motor may need replacement.

User setting of max. number of starts exceeded.

Evaluate setting. Evaluate stop and start levels to

increase pump runtime.

Moisture or water detected inside motor. Overhaul of

pump or motor is needed.

Check pump, valves and pipes for blockages. Pump

may need overhaul.

Check settings of DIP switches of IO 113. Check

warning and alarm threshold in IO 113 by using PC Tool

Water Utility.

Check motor relay (possibility of contact welding).

Check possible causes for tripping. Check pump,

valves and pipes for blockages.

Check local alarms and instructions on CUE.

Voltage on one or multiple phases is too high. Check

incoming voltage.

User-defined service interval is close. Arrange for

preventive maintenance on dosing pump.

Check the installation and operating instructions of

the dosing pump for remedy.

Check the installation and operating instructions of

the dosing pump for remedy.

Check the installation and operating instructions of

the dosing pump for remedy.
