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 Intellisys® controller.
The restart time delay, which is adjustable from 10–120
seconds, can also be adjusted while in the set routine
on the Intellisys® 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 Intellisys® 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 PWROUT 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 Intellisys® 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.
6. Use the up or down arrows to select the desired
delay time (10–120 sec.).
7. Press SET and the display will flash twice indicating
the change has beenmade.
8. Push the DISPLAY SELECT BUTTON or wait 30
seconds for the controller to automatically exit the
set routine. The display returns to READY TO START.
