Note
The shown functions of the preessure switches and motor
contactor are for understanding purposes only.
In reality, the information from the two pressure switches is
transferred directly to the control electronics, which in turn
controls the motor contactor.
When the appliance is switched off and the gun is open,
the pressure is taken from the system and it is without volt-
age.
Both pressure switches as well as the overflow valve and
the pressure retaining valve closed.
The motor contactors are open.
