Section II - Description

The Power$ync II™ controller allows the customer to select Auto Dual as an alternate control method. Auto Dual incorporates a timer which will turn the compressor off if it remains in the unloaded condition for a preset length of time. If the system pressure remains above the preset pressure for the programmed time interval, Power$ync II™ places the compressor in Standby Mode, with the drive and fan motors de-energized. The Power$ync II™ controller waits for an indication of demand, recognized as a drop in system pressure to a preset minimum pressure level, and automatically restarts the compressor.

Essentially equal to Continuous Run, Auto Dual goes a step beyond to offer the opportunity for additional power savings in a system with more dramatic differences in demand. As demand changes with shift changes or varying operations, the Power$ync II™ controller will allow the QSD™ compressor to go into Standby Mode when compressor output is not needed. Like the Continuous Run Mode, a properly sized air receiver will ensure that the compressor operates and reacts properly as air system demand changes.

NOTE

Refer to section VIII for Power$ync II™ operating instructions.

Electrical System

A diagram of the electrical system is shown in the parts manual shipped with the compressor. A wiring diagram is also included in the control panel of all Quincy compressors.

NOTE

Due to continuing product improvements and updates, it is suggested that the wiring diagram included in the control panel be used when servicing the electrical control.

NOTE

Standard drive motors are open, drip-proof, with a maximum ambient temperature rating of 40°C. They are not suitable for salt laden, corrosive, dirty, wet or explosive environments.

The standard QSD™ compressor utilizes 460V incoming power through an across the line magnetic starter. A transformer in the control panel reduces this voltage to 120 VAC for the various controls on the unit. These controls include the selector switch, pressure switch, timer, high air temperature (HAT) safety switches, solenoid valve and various indicator lights. Other incoming line voltages are available as options. A NEMA 4 electrical enclosure is standard.
