4. CONTROL FUNCTION OPTIONS
4.1 Automatic Re-start
Automatic re-start will allow the compressor to
start automatically after a break or failure in the
mains power supply. When this facility is enabled
the Remote start / Auto re-start indicator (L8) will
be lit.
1. To enable Automatic re-start select an
Automatic restart delay time of greater than
zero seconds using the ‘Program Mode’.
2. To disable Automatic restart select an
automatic restart delay time of zero seconds.
3. When power is restored after a break or
failure of the main supply power, the Remote
start / Auto re-start indicator (L8) will flash for
the programmed Auto re-start delay time.
This provides a warning before the
compressor re-starts. The compressor motor
will automatically re-start and continue to run
after the auto restart delay time expires.
4. The compressor will only automatically re-
start if the compressor was in the On-load,
Off-load or Standby mode when the break or
failure in main supply power occurred.
4.1.1 Automatic Restart Delay Time
The Auto restart delay time can be adjusted using
the ‘Program Mode’.
In multiple compressor installations, staggered
restarting can be achieved by adjusting the delay
time of each compressor differently.
Example - Four compressor installation:-
Compressor Autorestart delay time
1 60 seconds
2 120 seconds
3 180 seconds
4 240 seconds
4.2 Remote Start/Stop Facility
4.2.1 Remote Start
The remote start facility will enable the compressor
to be started from a remote location.
1. When this option is selected, the Remote
control/Auto re-start indicator (L8) will be lit
and the START button (B2) on the
compressor panel is disabled; all STOP
functions are unaffected.
2. To enable the remote start facility connect a
length of wire between terminal X2/1 and
controller terminal X01, pin 7.
3. The compressor can be remotely started if
remote start terminal X01, pin 4, is connected
via a remote normally open button or other
switching device, to terminal X2/1. The
connection can be a pulse of at least 0·5
seconds or continuous.
4.2.2 Remote Stop
Note: Wire LK1 must be removed to enable the
remote stop to function.
The remote stop facility will enable the compressor
to be stopped from a remote location.
1. The remote stop is active at all times,
regardless of the remote start facility being
enabled.
2. The compressor can be stopped remotely by
disconnecting the wire link between terminals
X2/1 and X2/2 via a remote, normally closed
button or other switching device.
4.3 Remote Load/Unload
The remote load/unload facility enables the
compressor to be pressure controlled by a remote
pressure switch, pressure control system or
cascade panel.
1. To enable the remote Load/Unload facility
connect a length of wire between terminal
X2/1 and controller terminal X01, pin 5.
