6 Mains supply fault
MP
204/CUE
Phase missing or drifted
Check voltages between phases, pre-fuses and circuit
breakers.
9
Motor-phase sequence
reversal
MP 204 Phases interchanged Check phase sequence.
10
Pump (power line)
communication fault
IO 113 Communication to SM 113 Check cables between IO 113 and SM 113.
11
Water-in-oil content too
high
IO 113 Water-in-oil compartment
Water-in-oil content has passed threshold. Lower shaft-
seal and oil needs replacement.
12
Motor operating-time
service interval limit
exceeded
CU 362 Service interval
User-defined service interval has been reached.
Arrange for preventive maintenance.
15 SCADA callback fault CU 362 SCADA failed to respond
Check cellular network connection. Check if SCADA
phone number is correct. Check status of external
SCADA system.
16 Other fault CUE Fault reported by CUE Check fault locally on CUE drive.
17
Capacity too low
(Performance
requirements not met)
Dosing
pump
Dosing volume not met
Check status of dosing pump. Perform calibration
of dosing pump.
18

commanded (test) trip
MP 204 Test trip activated Test trip activated on MP 204.
19
Diaphragm break - dosing
pump
Dosing
pump
Diaphragm break detected Replace diaphragm in dosing pump.
20
Motor insulation resistance
low
IO 113/MP
204
Insulation resistance
too low
Check setting. Motor may need replacement.
21
Motor max. starts per hour
limit exceeded
CU 362 Max. starts exceeded
User setting of max. number of starts exceeded.
Evaluate setting. Evaluate stop and start levels to
increase pump runtime.
22 Motor moisture switch IO 113 Moisture switch activated
Moisture or water detected inside motor. Overhaul of
pump or motor is needed.
24 Motor/pump vibration high IO 113
Vibration threshold
exceeded
Check pump, valves and pipes for blockages. Pump
may need overhaul.
25 Setup conflict IO 113 Setup conflict in IO 113
Check settings of DIP switches of IO 113. Check
warning and alarm threshold in IO 113 by using PC Tool
Water Utility.
26
Load continues despite
motor relay is off
MP 204
Current drawn when it
should not be
Check motor relay (possibility of contact welding).
27
Motor protector activated
via DI

service information)
CUE
Change bearings reported
by CUE
Check local alarms and instructions on CUE.
32 Motor high voltage
MP
204/CUE
Voltage too high
