5 Electrical System

5.1 Electrical System Overview

The electrical enclosure contains the main disconnect, the motor starters, and the control components.
All internal control power is derived from the three phase input power. The Electrical section of this
manual describes the following:
•

Electrical Control Panel

•
Motors and Motor Starter Circuits
•
Fault Detection
5.2 Electrical Control Panel
Operator Control Station
The operator controls the intensifier pump through the Operator Control Station (OCS) on the front of
the electrical enclosure see Front Control Panel in the Operation section. Refer to the supplemental
control manual for additional details about control operation and features.
Disconnects and Fuses
The electrical cabinet is powered by 3-phase AC incoming power. All motors are run using the same 3-
phase power input. Some control enclosures may have a transformer for 110VAC as required.
All field components (i.e. solenoid valves, sensors, etc.) use 24VDC power. Fusing is provided for the
PLC outputs, 24VDC power supply, and the transformer (if present). Refer to the electrical schematic
for fuse sizes and locations. Some spare fuses are included with the controller. All fuses can be
purchased from Hypertherm or an electrical supply store.
Remote Operation Wiring
Hypertherm HyPrecision 100D/150D pumps come standard with built in functionality for REMOTE
operation. The pump includes two options for external control that integrators can use: External
Pressure Control and Remote Pump Control.
Remote Pump Control (RPC) deactivates the CONTROLS ON, PUMP ON, and COOLING ON at
the front panel of the pump. These inputs are then solely controlled from a remote source. PUMP OFF
and EMERGENCY STOP are active at both the front control panel and the remote source. RPC is
activated by turning the key switch to the remote setting. The wire connections and terminal block
information are included in the schematic for this pump.
