1) | For connection to the AC voltage mains, a DC solenoid must be used, which is controlled via a rectifier (see table). |
For individual connection, a mating connector with integrated rectifier can be used (separate order). | |
2) | Mating connectors (separate order). |
3) | Version "D3" requires installation of a throttle insert "B08" in port P of the pilot control valve! |

Notices!
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 the operation, separate order, material no. R900024943). When the manual override is blocked, the actuation of the solenoid must be prevented! The simultaneous actuation of the solenoids must be prevented!Inductive position switch type QM: electrical connection

Stroke setting, mounting options
The stroke of the main spool is limited by the stroke setting.
The piston stroke is shortened by untightening the lock nut (17) and clockwise rotation of the adjustment spindle (18). For this, the control chamber has to be depressurized.
