Introduction to Power$ync II™

!WARNING

Always disconnect and follow lockout/tag-out procedures before attempting any repair or adjustment to any electrical component on this compressor.

The Power$ync II™ control for the QSD model compressors consists of a two-stage oil-free airend and an associated computerized controller. Together, these features have been designed to provide the best full-load and unloaded efficiencies available in the compressor industry. Besides providing outstanding single machine efficiencies, this control includes multi-machine control.

This control uses four pressure transducers and four RTD temperature probes for the computerized controller. The pressure transducers are located in the control panel. Each transducer is plumbed to its own specific location. Pressure is measured at the discharge of stage one, discharge of stage two, and the discharge of the package. Package discharge is located on the customer side of the package check valve. Fluid pressure is also measured.

The RTD temperature probes are installed at the discharge of each compressor stage, at the inlet of stage two and at the discharge of the package.

There is a coolant flow switch to prevent the unit from running if there is no coolant flow. If the unit is shut down by the coolant flow switch, the control will display ‘Emergency Stop Button Pressed’.

Back-up Mode Operation

The Power$ync II™ control on QSD™ compressors has a built-in feature not found on other oil-free compressors. In the unlikely event of a failure of any component of the electronic control, the electronic control may be switched off and the machine operated in Back-up Mode until the problem is taken care of.

The Back-up Mode must not be used to bypass a shutdown condition that occurred in Power$ync II™ Mode. The cause of the shutdown must be found and corrected before operating the compressor any further. The Back-up Mode must not be used for continuous operation.

The Back-up Mode is a separate control circuit using pressure switches, snap disk temperature switches and a PLC. The settings of the pressure switches should be verified before operating in this mode. After disconnecting power, PS1 should be set to open at the unload pressure of the package and is the only adjustable pressure switch. PS2 and PS3 are not adjustable and are factory set to open at 23 psig. PS4 is not adjustable and is factory set to close at 15 psig.

With these settings verified, activate the Back-up Mode as follows:

1)Disconnect power from the compressor.

2)Open the electrical enclosure door, and turn the selector switch to Back-up Mode.

3)Close the electrical enclosure door and reconnect power to the compressor.

4)Wait thirty seconds and press START.

Do not switch modes with power on the compressor!
