4. Design and functioning
Standstill of the system
• When the system is at rest the intake controller -2- is
closed by the compression spring in the actuating
cylinder -2.1-.
•
The solenoid valves -19 + 20- are de-energized.
•
The pressure reservoir -6- is bled via the solenoid
valve -20- and actuating cylinder -2.1- into the in-
take channel.
Stopping of the system
• After pressing the OFF-key on the operating panel,
the solenoid valves -19 + 20- are de-energized.
•
The pressure control valve -2.2- in the intake regu-
lator -2- closes and the system is relieved.
•
After approximately 30 seconds, the electric motors
- 3 + 25- shut down.
•
The cooling water solenoid valve -28- (only in WS-
units) de-energizes and closes.
