OPERATION

POWER OUTAGE RESTART OPTION

For customers that have interruptions in their incoming power supply to the compressor and must maintain an uninterrupted supply of compressed air, the Power Outage Restart Option allows an Intellisys compressor to restart automatically 10–120 seconds (adjustable) after incoming power is restored.

The Power Outage Restart Option is turned on by using the customer set routine on the IntellisysR controller. The restart time delay, which is adjustable from 10–120 seconds, can also be adjusted while in the set routine on the IntellisysR controller. Any time power is restored to the compressor after a power interruption and if the compressor was running when power was lost, a horn located on the side of the starter box will sound during the restart time delay (10–120 seconds), after which the compressor will automatically start. After starting, the compressor will return to the mode of operation that the compressor was in prior to the power interruption.

To operate in the power outage restart mode, proceed with following steps:

1.Power up the unit and wait for the IntellisysR display to read READY TO START.

2.Press the SET button once to enter the customer set point routine. The Set Offline Air Pressure indicator will light and the display will show the set point pressure.

3.Press and release the SET button multiple times until the message PWR OUT RSTR OFF is displayed.

4.Push the up or down arrows to change to the desired condition. ON in the display indicates Power Outage Restart is turned on and OFF in the display indicates Power Outage Restart is turned off.

5.Once the selection has been made, press SET button to put the selection into IntellisysR memory. The display will flash twice and the message will change to STR DELAY 10 Sec if the option was turned on. This message will only display if the Power Outage Restart Option is turned on.

Function test

To test the operation of the Power Outage Restart Option:

1.Slowly open the main isolation valve.

2.Push the green START button on the IntellisysR display to start the compressor.

3.The compressor will load automatically if there is a sufficient demand for air. Allow the compressor to load.

4.Open the main disconnect to remove power from the compressor.

5.Close the main disconnect to reapply power to the compressor.The horn will sound and the IntellisysR display will read START IN

___SEC.The display will count down the time until the compressor starts automatically and the horn stops. After starting, the compressor will automatically return to the same mode of operation as prior to the power interruption.

Fault Analysis

1.If the IntellisysR display indicates the count down message and the horn does not sound, check the wiring of the horn.

2.If the IntellisysR display does not indicate the count down message, the horn does not sound and the unit does not restart automatically, verify that the Option has been turned on.
