Malfunctions in operation

Malfunction Cause

Remedy

Temperature rise in the motor
Motor temperature monitoring
unit trips

Water cooling not active.

Coolant supply inadequate
- Deposits in the cooling
channels
- Faults in the external cooling
system

Check and switch on if
necessary
Check water circuit
- Check, and clean if
necessary
- Follow plant supplier’s
instructions

Overpressure in the cooling
system

Heavily soiled coolant
Cooling channels blocked

Malfunctions in the external
cooling system

Filter coolant
Check and, if necessary,
clean
Follow plant supplier’s
instructions

Table 9: Malfunctions water cooling
