1) The ignition temperature of the process and operating medium used must be over the maximum solenoid surface temperature.
2) The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

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!

Switching times (= Contacting at the pilot control valve until start of opening of the control edge in the main valve and change in the pressure value by 5 %)

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.

The stroke of the main spool is limited by the stroke setting.

The piston stroke is shortened by untightening the lock nut (19) and clockwise rotation of the adjustment spindle (20). For this, the control chamber has to be depressurized.
