This initiates a controlled shut down
sequence. The compressor will unload, the
drive motor will stop and the Start indicator
(L8) will flash slowly for the blowdown period.
See para 2.3 ‘Program mode settings’.
2. The compressor motor cannot be re-started
during the blowdown sequence. If START
(B2) is pressed the start indicator will flash
quickly and the compressor will enter the
Standby mode and start automatically when
the blowdown time expires.
CAUTION: The compressor should not be stopped
during a start sequence.

and RESET (B6) pressed during the
blowdown time, the Start indicator will slow
flash for the remainder of the normal

The display will reset to show delivery pressure 60
seconds after VIEW is last pressed.
1.6 Service Interval Timer
The controller uses a countdown timer which can
be reset to programmed maximum each time a
service is carried out. The maximum reset hours
can be adjusted to suit site conditions and/or
service schedule requirements. When the timer
reaches zero hours, indicator L3 will slow flash to
indicate a service is due. When the service has
been completed the service countdown timer can
be reset by entering the program mode, selecting
the service interval hours display (indicator L3),
and pressing STOP . The service interval
countdown timer will reset to the hours displayed
on the program mode service interval setting. The
service due alarm can be reset by pressing
RESET after the above procedure has been
completed.
The compressor must be stopped and the power
isolated to carry out the required service (see
'Safety Procedures'). On completion of the service
the service interval timer must be reset.
When in the normal running mode the 'hours
remaining until next service due' can be viewed at
any time. Press VIEW until indicator L3 is
illuminated and the display shows the total hours
run. Press and hold PLUS and the display will
show the hours remaining until the next service is
due until PLUS is released.
