Manual OverRide (MOR)
All controls are available with a Manual OverRide (MOR) for temporary actuation of the control to aid in
diagnosis. FNR controls always include MOR functionality.

Warning
Depressing the plunger causes the pump to go into stroke which will move the machine or mechanism.
Ensure the vehicle or machine is in a safe condition (wheels off the ground or mechanism disconnected)
before attempting to use the MOR feature.
An O-ring seals the MOR plunger. Initial actuation of the function requires additional force to overcome
the O-ring resistance. A threshold force of 45 N is typically required at first actuation. Additional
actuations typically require a threshold force of 12 N to move the MOR plunger. Force required to keep
the pump at full stroke is typically 51 N. Do not expect proportional control of the pump using the MOR.
Refer to control flow table for the relationship of solenoid to direction of flow.
