Manual Over Ride (MOR)
All controls are available with a Manual Over Ride (MOR) either standard or as an option for temporary
actuation of the control to aid in diagnostics.
Forward-Neutral-Reverse (FNR) and Non Feedback Proportional Electric (NFPE) controls are always
supplied with MOR functionality.

Unintended MOR operation will cause the pump to go into stroke. The vehicle or device must always be
in a „safe“ condition (i.e. vehicle lifted off the ground) when using the MOR function.
The MOR plunger has a 4 mm diameter and must be manually depressed to be engaged. Depressing the
plunger mechanically moves the control spool which allows the pump to go on stroke.
The MOR should be engaged anticipating a full stroke response from the pump.
Warning
An o-ring seal is used to seal the MOR plunger where initial actuation of the function will require a force
of 45 N to engage the plunger. Additional actuations typically require less force to engage the MOR
plunger. Proportional control of the pump using the MOR should not be expected.
Refer to control flow table for the relationship of solenoid to direction of flow.
