7 Operation
7.1 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.
Actuating the manual override with automatic reset (non-detenting actuation)
• Use a screwdriver to press down the plunger of the manual
override as far as possible.
The valve reverts to the switching position.
• Remove the screwdriver.
The valve reverts to the basic position.
