Theory of operation
Normally Closed Electric On-Off Control Characteristic
The normally closed configuration on/off control directs the pump to its pressure compensation setting
when no current is applied. When an electric current is sent to the normally closed configuration control,
the pump pressure decreases to the low-pressure standby setting. This control does not have Load Sense
functionality, but rather acts as a Pressure Compensation control when not energized, or is directed to its
low-pressure standby when energized. This control is especially useful for machine startups, as the pump
can be directed to its Low-Pressure Standby setting during startup to reduce the load on engine starters.
Normally Open Electric On/Off Control Characteristic
The normally open configuration on/off control directs the pump to its low-pressure standby setting
when no current is applied. When an electric current is sent to the normally open configuration control,
the pump pressure increases to the pressure compensation setting. This control does not have load sense
functionality, but rather acts as a pressure compensation control when energized, or is directed to its
lowpressure standby when de-energized. This control is especially useful for machine startups, as the
pump can be directed to its low pressure standby setting during startup to reduce the load on engine
starters.
