A blockage of the shredder blades should be recognised quickly.
Monitoring of the permitted current range of the electric blade motor with the “over” function. As soon as the power drawn by the motor leaves the permissible range, for example an overload because the blades are blocked, the relay output is tripped, and a contactor switches the pump off.
– Rapid shutdown in the event of blockage
– Motor protection
– Minimisation and prevention of downtime
