Manual override

The solenoid valve can be switched manually when it is not actuated or not supplied with power by
means of the manual override (HHB). The manual override is designed in a non-detenting/detenting
manner.
Note
The ejector pulse (solenoid coil 14) can only be switched with the manual override when
it is not supplied with power (no voltage at connector M12). An ejector pulse via the
manual override is not possible during normal operation.
