8.8.2 Protective functions
8.8.2.1 Activating/deactivating thermal motor protection
Thermal overload results in immediate tripping and an alert message is output.
Restarting will only be possible after the motor has cooled down sufficiently. The
stop threshold value is set at the factory for monitoring with a PTC sensor or a
thermal circuit breaker. If other thermocouples are used, the value has to be set by
KSB Service.
NOTE
Thermal motor protection cannot be activated/deactivated while the motor is in
operation.
