Section VIII - Power$ync II™ Operation

While running in Back-up Mode, there is no power going to the electronic control. The displays on the electronic control will be dark and the keypad will be inactive. Pressures and temperatures may be read on the gauges located at the package discharge connection.

Single Machine Operational Modes

There are two modes of operation that can be used for single machine installations, Continuous Run and Auto Dual.

Continuous Run

In Continuous Run Mode, the compressor uses an adjustable pressure deadband to match compressor output to system demand. As the pressure rises above the full-load pressure setting, a signal is sent to unload the airend, reducing the air delivery. Should the pressure rise to a point indicating there is no system demand, the control will unload the compressor and blow the piping down to atmospheric pressure. It will continue to run in this unloaded state until system pressure drop indicates additional air demand.

This control mode is best used for systems that have only brief periods of time with no system demand. Systems with little compressed air storage capacity will also run better with a control scheme using a pressure deadband to moderate changes in loading levels.

Auto Dual Control

This method of control operates identically to the Continuous Run Mode when responding to a system demand. If there is no system demand, Auto Dual control goes a step beyond Continuous Run to provide additional power savings. In the Auto Dual Mode, the control will start a shutdown timer when the compressor unloads. The timer will count down a preset waiting period. If there has been no drop in system pressure during this waiting period, the control will turn the compressor motor(s) off and will stand by, continuing to monitor system pressure. When a demand returns to the system, the controller will restart the compressor to satisfy the air requirements.

Auto Dual Mode is best used for systems that have extended periods (usually half an hour or more) during which there is no system demand. A very small continuous system demand can be handled with adequate compressed air storage capacity and a reasonable pressure deadband, allowing the power savings associated with having the compressor turned off.

Auto Dual Time Delay

The factory setting for this delay is ten (10) minutes. The purpose of the delay is to prevent the motor from starting too many times within a given period. To maximize the energy savings benefit of having the machine off instead of just unloaded, this timer should be set low enough to allow the machine to turn itself off during periods of no demand.

If the compressor attempts to start too many times, a safety timer will be activated which forces a 25-minute cool-down period. The control will then reset and allow the machine to shut down based on the adjustable timer setting.

Multiple Machine Operational Mode

The control method used for multiple Power$ync II™ compressor installations is the Network Mode. Connecting multiple machines to form a network, scheduling machines and sequencing machines are thoroughly covered in this section. In Network Mode, all compressors share information about their capacity, configuration and load setting.

Network Mode uses an adjustable pressure band for controlling the compressor response to changes in system demand. With the system at full load (all compressors operating at their maximum output) an increase in system pressure above the set pressure indicates a drop in demand. The control will respond by unloading the trim machine in the sequence.
