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.
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
been made.
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.
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.
