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 o 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 owtable for the relationship of solenoid to direction of ow.
