Error Signals

The following conditions can cause a fl ashing red or solid red error light. If one of these error indica-
tions is visible, troubleshoot the system based on the following:
Low Water Remedy: Check suction pressure. If suction pressure is normal the unit restarts itself.
Overheating – Motor Possible causes: Insuffi cient cooling ambient temperature is too high, motor
overloaded. After the cause has been remedied, the malfunction has to be reset by cutting off the
power supply for > 30 seconds.
Overvoltage Possible cause: Check main supply, supply voltage too high, peak voltage due to switch-
ing heavy loads on the network. Find the cause and take countermeasures (e.g. line fi lter, RC-elements).
Disconnect the power supply for > 30 seconds.
Undervoltage Possible cause: Check main supply, faulty fuse or out of phase.
Overload Possible causes: the pump is working at a capacity signifi cantly in excess of its performance
data. Disconnect the power supply for > 30 seconds.
Overtemp. Heat Sink The thermal sensor on the heat sink indicates over temperature. Possible causes:
insuffi cient cooling, ambient temperature too high or motor overload. After remedy, cut off power for
> 30 seconds to reset.
Sensor Fault A sensor signal of below .5 VDC was received due to bad sensor, broken cable or bad
connection. After remedy cut off power for > 30 seconds to reset.
