HPC Control Connector
This is a 6-pin Amphenol connector used to interface the pump to the Master
Controller.

Oil Level/ Temperature Gauge
This gauge indicates the level of oil in the reservoir. It is mounted directly to the
oil reservoir. The system should not be operated with less than 3.5 gallons of oil.
3.7.
Voltage Selector Switch
This switch allows the 1001P Hydraulic Power Supply to be used with either
115 VAC or 230 VAC 60 Hz power, single phase. See 2.2. and B-30224
3.8.
Fuses
All replaceable fuses are mounted in Electrical Box #1 on the front panel of the
Power Supply. See 2.2. for appropriate ratings and Drawing B-30223 for
location.
3.9.
Oil Level/ Temperature Switch
This switch is located inside the reservoir. It shuts down the unit if the oil
level is too low or if the oil temperature exceeds 140° F. Indicator lamps are
illuminated on the front panel of control box #1 if the oil level is too low or the
Hydraulic Power Supply is over its temperature limit.
3.10. Filter Switch
The filter switch is mounted on the filter assembly, located at the output of
the pump. If the differential pressure across the filter element exceeds 35 psi,
the switch is momentarily activated, de-energizing the pump motor starter.
If this occurs, it generally indicates that the filter element is dirty and needs
replacement. An indicator lamp is illuminated when the filter needs replaced.
