Exact
Possible cause and solution
Low load detected. The pump is
10
running dry.
Motor overload. The motor might be
11
faulty or a viscous medium is present.
The circuit is too hot and the power
22 was reduced to less than 2/3 of the
rated power.
The circuit is too hot to run and the
23
pump has stopped.
Hardware overcurrent protection
24
triggered.
25 Line voltage is too high.
Line voltage is too low for proper
26
operation.
Average motor current was too high,
31 pump load is much higher than
expected.
42 LED Fault
The voltage on DC link shunt not
44
within the expected range
48 15 V is not present
51 Motor does not behave as expected.
