Operational Description

The Electronic Displacement Control (EDC) combines electronic proportional stroke control with mechanical pressure override. There are four configurations for this control P-E Normally Open (N.O.), P-F Normally Closed (N.C.), P-E/F N.O with Load Sense and P-F/F N.C. with Load Sense.

The pump stroke will respond to changes in the electrical command signal sent to the EDC proportional valve, provided that the pressure is below the mechanical override setting. The command signal can be changed in response to external events such as a change in engine RPM, system pressure, horsepower or other externally monitored condition ( on graphs below). If the pressure reaches the override setting, the mechanical control overrides the electrical command signal and de-strokes the pump ( 2 ). If the pressure drops back below the setpoint the pump stroke returns to the level set by the proportional command ( ). Normally Open P-E Control - An increase in the command to the proportional valve results in a decrease in pump stroke. Zero command equals Full Stroke provided the outlet pressure is less than the pressure override setting. In the event of a loss of the electrical signal, the P-E control will operate as a standard pressure control.

Normally Closed P-F Control - An increase in the command to the proportional valve results in an increase in pump stroke. With Zero command the pump will remain at Neutral.
