Description
Low load detected. Pump is running dry.
Motor might be faulty or viscous medium is present.
Circuit is too hot and power was reduced to less than 2/3 of rated
power.
temperature
Circuit is too hot to run, pump stopped
Hardware overcurrent protection triggered.
Line voltage is too high
Line voltage is too low for proper operation.
Power correction circuit current cannot be controlled
Average motor current was too high, pump load is much higher
than expected
Electrical circuitry did not pass self-test.
One of the display segment diodes is faulty (open/short)
Display board does not detect proper connection to main board,
but power supply is present
Voltage on DC link shunt (R34) not in expected range
During operation, expected values are -55 °C..150 °C
During MFG. TEST, this is 0 °C..50 °C. During operation, expected
values are -55 °C..150 °C
reference
outside
Comparison between internal references does not match
15V power supply is not 15V.
Pump has to be reprogramed.
Motor does not behave as expected
Motor temperature is too hot to operate.
Pump model not valid or out of reach.
Turn power on and off.
Check electrical installation and fuse.
