WARNING
Ensure that all protective covers/guards are in
place before attempting to start the machine.
NOTICE
The language and units of measure displayed on
the Intellisys controller will be pre–set before

Service Department, Distributor or Air Center.
Prior to starting
Refer to diagram T5716 above
Check that the oil level is at least visible in the center of
the sight glass, add oil if necessary. Refer to
maintenance procedures for setting correct level.
Ensure that the discharge air isolation valve is open.
Switch on the main electrical isolation switch. The
control panel will illuminate, indicating that the line and
control voltages are available.
The contrast of the display may be adjusted by turning
the small screw which is on the right hand side of the
controller when accessed through the starter cabinet
door.
Initial check sequence
The controller will perform an initial check sequence if
the compressor (1) receives initial power to the
controller or (2) has experienced an alarm reset. While
the initial check sequence occurs, the controller will
display a “Checking Machine” message.
During the initial check sequence, the controller will
check the control system for proper operation. During
this time, if any items are found inoperative an alarm will
occur and the unit will not start.
After completion of the initial check sequence, the
controller will then display “READY TO START’. This
process should be completed within 10 seconds.
