Return to Low Pressure Standby
The pump will remain in the high pressure standby mode until the valve in operation is returned to neutral. When
this occurs, the feed into the signal line from that valve will be cut off. The signal pressure will drop because of the
drain orifice plug passage is open to the pump case drain. When there is no signal line pressure the pump
immediately returns to a low pressure standby condition.
NOTE: The high pressure limiting spool is adjustable and can be removed for inspection.
