Monitoring and safety devices
Pressure relief valve
If the lever of the high-pressure gun is released, the cir-
culation valve opens but the high-pressure pump re-
mains in operation. The high-pressure jet is immediately
available when the trigger gun is opened again.
Motor circuit breaker
The motor circuit breaker shuts off the device if power
consumption is too high.
Winding protection contact
A winding protection contact is only installed in models
with 900 l/h.
The winding protection contact in the motor winding of
the pump drive sends a signal to the controller in the
case of thermal overload. This switches the motor off.
