Notes!
- Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for actuation, separate order, material no. R900024943). When the manual override is blocked, the operation of the solenoid must be prevented!
- The simultaneous actuation of the solenoids must be prevented!
Inductive position switch type QM: electrical connection
The electric connection is realized via a 4-pole mating connector (separate order) with connection thread M12 x 1.
