Excess current protection
The motor is protected by a protection switch with thermal and elec-
tromagnetic tripping. The trip current must be adjusted directly on
these breaker.
Pump failures lead directly to stopping the command for the pump
and generate a collective fault signal (SSM). After rectification of the
fault's cause, an acknowledgement is requested before restarting the
pump.
All motor protection functions are active in the hand mode.
