CONTROLLER ALARMS
In the event of an alarm, the controller will execute an emergency
stop, the alarm L.E.D. [10] will illuminate and an alarm message will be
displayed. The arrow keys [23] should be used to index the display for
any additional alarm messages. An alarm is reset by depressing set
[21] twice within a 3 second period after the fault has been rectified. The
compressor will restart only when all alarm conditions have been
rectified. The following alarm messages may be displayed (For fault
correction see the Fault Finding section):
STARTER FAULT
The contactor sequence during start or stop is incorrect.
AIREND TEMPERATURE
The airend discharge temperature is above the high temperature
set point.
MOTOR OVERLOAD
The motor overload contacts are open. The motor overload must be
reset before the controller can be reset.
REVERSE ROTATION
No sump pressure is detected after the first 2 seconds of running.
Isolate the machine and reverse the mains supply connections before
resuming.
OVER PRESSURE
The line pressure is 15 psi (1 bar) greater than the rated discharge
pressure.
TEMPERATURE SENSOR 1
The airend temperature sensor/ connecting cable has failed.
TEMPERATURE SENSOR 2
The separator tank temperature sensor/connecting cable has
failed.
PRESSURE SENSOR
Indicates pressure transducer failure / connecting cable fault.
FAILED CALIBRATION
During calibration routine, a 10% of scale error has been detected.
Ensure that the separator is completely blowndown and repeat
calibration.
CONTROL POWER LOSS
The 48Vac signal is not present at the controller.
REMOTE START FAILURE
Momentary remote start has not disengaged before star–delta
transition. This alarm is active only if the remote start/stop is enabled.
REMOTE STOP FAILURE
The momentary remote stop switch has not disengaged when the
start signal is received. This alarm is active only if the remote start/stop
is enabled.
EMERGENCY STOP
The emergency stop button is engaged.
LOW SUMP PRESSURE
The sump pressure drops below 15 psi (1 bar) during normal
operation.

INTELLISYS OPTION
FIELD OPTION/S
Before installation and operation of this option, these instructions
should be studied carefully to obtain a clear knowledge of the option
and its application to the compressor.
REMOTE START/STOP
The Remote Start/Stop Option allows the operator to control the
compressor from a remote mounted start/stop station.Terminal points
are provided in connector J1 in the top of the lntellisys controller; one
a connection for a normally closed stop switch (terminals 3 and 4), and
one for a normally open, momentary contact start switch (terminals 5
and 6). Refer to the compressor wiring schematic for specific
connection points.
For safety, a selection is available in the lntellisys
disable the remote start and stop function.This allows the compressor
to be fully controlled by the lntellisys
start/stop station.
If the remote start switch is momentarily closed, the lntellisys
starts the compressor.The remote stop switch is normally closed. If the
remote stop switch opens, the compressor will unload and stop.The
compressor cannot restart until the remote stop switch has been reset
to a closed position. (EMERGENCY STOP will display on the
lntellisys if the stop switch is not closed).
To operate in the remote start/stop mode, proceed with the
following steps:
1. Press the SET button until the message REMOTE S/S OFF is
displayed.
2. Push the up or down arrows to select the remote start/stop function
(on or off). REMOTE S/S OFF in the display indicates remote start/stop
is disabled (off). REMOTE S/S ON in the display indicates remote
start/stop in enabled (on). Press the SET button to store the function.
The display will flash to acknowledge. Press the DISPLAY SELECT
button or wait 30 seconds for the controller to automatically exit the set
routine.The display returns to READY TO START.
3. Start the compressor with the Start button on the Intellisys control
panel.The compressor must be started locally first before the Remote
Start/Stop buttons are activated by the lntellisys .
