EMERGENCY STOP
1. Press 'Emergency stop button' [26] and the
compressor will stop immediately.
2. Turn off electrical isolator.
INSTRUMENT PANEL FUNCTION
1 PACKAGE DISCHARGE PRESSURE L .E .D.
This will illuminate when the display indicates the
package discharge pressure.
2 AIREND DISCHARGE TEMPERATURE L .E .D .
This will illuminate when the display indicates the
airend discharge temperature.
3 SUMP PRESSURE L .E .D .
This will illuminate when the display indicates the
sump pressure.
4 SEPARATOR PRESSURE DROP L .E .D .
This will illuminate when the display indicates the
separator pressure drop.
5 TOTAL HOURS L .E .D .
This will illuminate when the display indicates the
total compressor running hours.
6 LOADED HOURS L .E .D .
This will illuminate when the display indicates the
total loaded compressor hours.
7 LOAD/UNLOAD L .E .D .
This will illuminate when the compressor is running
onload.
8 MODULATION L .E .D .
This will illuminate when the compressor is running
in modulation mode. (Note: capacity modulation will
occur only if the appropriate regulation pneumatics
are fitted to the compressor).
9 UNLOAD L .E .D .
This will illuminate when the compressor is running
in unload mode.
10 ALARM L .E .D .
This will flash when a warning condition exists.
The warning detected will be displayed and the
compressor will continue to run. The warning can be
reset by depressing set [21].
It will illuminate when an alarm condition
has occurred. The compressor will shutdown
immediately. The alarm can be reset by depressing
set [21] twice within 3 seconds.
OTHER L .E .D .s
These will illuminate during the set point routine to
indicate which .
11 L .E .D .–Set off line pressure.
12 L .E .D .–Set on line pressure.
13 L .E .D .–Select control mode.
14 L .E .D .–Set star delta time.
15 L .E .D .–Set auto restart time.
16 L .E .D .–Select options.
17 L .E .D .–Not used.
6
INTELLISYS® OPTION
18 L .E .D .–Not used.
19 DISPLAY SELECT BUTTON
Press to index through compressor operating
conditions. The corresponding L.E.D. will illuminate
adjacent to display.
This is used to select alternative status displays (after
approximately 5 minutes, the display defaults to the
package discharge pressure). Depressing this button
in the set point routine will cause exit to checking
machine for 2 seconds, then ready to start.
20 LOAD/UNLOAD BUTTON
These are used to manually switch the compressor
between a loaded control mode (e.g. on/off line) and
unloaded running. See L.E.D.
21 SET BUTTON
Depressing this button when the compressor is
stopped will enable entry into the set point routine.
When in the set point routine, depressing this button
will cause the controller to move on to the next set
point setting, saving the new value if one has been
entered.
A warning reset is obtained by depressing this
button (while the machine is running). An alarm
reset is obtained by depressing this button twice
within 3 seconds (the alarm condition will remain if
the indicated fault has not been rectified).
22 LIQUID CRYSTAL DISPLAY
This indicates the status of the compressor, set up
parameters and warning/alarm messages. When
the compressor is running, the display will normally
show the package discharge pressure.
23 ARROW KEYS
These are used to index through warning and alarm
messages. In the set point routine, these buttons
are used to increase/decrease set point values and
enable/disable some operation conditions.
The arrow keys are also used to select pressure
bands 1 () or 2 () during normal operation of the
compressor.
24 START BUTTON
This button when depressed will cause the
compressor to start and load automatically, provided
that the controller detects a demand for air.
When pressed in the display mode, it will cause exit
to checking machine for 2 seconds, then ready to
start.
25 UNLOADED STOP
This button when depressed while the compressor
is running, will unload the compressor (if not already
unloaded) for 10 seconds and then stop. This is the
normal method for stopping the compressor. If the
compressor is already stopped, it will execute an
L.E.D. check (all the L.E.D.s should illuminate) and
display the controller software revision.
