Terminal Strip - This device provides an interconnection between the GD Pilot controller and the low
voltage hardware such as sensors and switches within the enclosure.
Main Starter
For 3 Phase variant models, a full-voltage starter provides control and overload protection for the main
drive motor. Wiring diagrams for configured voltages are illustrated in the following pages of this section.
The overloads are adjustable and are factory set based on the motor nameplate amps and the
instructions located inside the control box door.
For 1 phase variant models, a variable speed drive provides the overload protection for the main drive
motor as well as limited compressor speed modulation.
Read the Operator's Manual before operating the compressor. It is critical that
the detailed instructions for the controller, found in the controller manual are
read and understood. Once the appropriate parameters have been selected into
the controller, compressor operation may commence. For convenience, a
"Quick Start" excerpt from the controller manual is shown in Section 3.
