2.8 Motor protection
CAUTION
Limited winding protection with supply voltages
less than 115 V AC.
With supply voltages less than 115 V AC, the self-locking
mechanism of the winding protection can be limited. After
cooling, this can cause the pump to start automatically.
Ø
When overheating, switch the pump off to avoid an auto-
matic restart.
Overheating protec-
tion, blockage pro-
tection
The pump motor has a temperature sensor in the motor winding. If
the temperature is excessive or the motor is blocked, the vacuum
pump switches off.
Restart procedure
If the vacuum pump switches off due to these safety measures, the
fault must be reset manually: Disconnect the pumping unit from the
power supply or acknowledge the fault message on the controller -
> Eliminate the cause of the error -> Allow the vacuum pump to cool
down -> Restart the pumping unit
