ROUTINE OPERATION

1.1

Starting

1. Switch mains power ON at the isolator. The
display will show the control program
identification and the Power on indicator (L9)
will light.
2. After a few seconds the Delivery pressure
indicator (L1) will light and the display will
show the delivery pressure in Bar. See para
1.5 'Oil temperature and Hours run display'.
3. The Remote start/Auto restart indicator (L8)
will light if the Remote start or Auto restart
facilities have been selected. See para 4
'Control Function Options'. If a fault exists,
one of the alarm or trip indicators will flash.
See para 1.9 'Control Panel indicators' for
possible start-up faults.
To start the compressor press START (B2).
4.
CAUTION: Do not repeatedly start and stop the
compressor.
Note: the compressor motor may appear to turn
slowly for the first few revolutions before running
up to speed. This is normal and should not be
considered a fault condition.
5. Provided pressure at the delivery point is
below the P2 pressure set point the
compressor will start and run. If pressure is
above the P2 set point the compressor will
enter 'Standby' mode and the Start indicator
(L8) will flash. The compressor will
automatically start and run when delivery
pressure falls below the P2 set point.
6. The compressor will not start from the front
panel if the Remote start facility is enabled.

OPERATION

WARNING
Lethal voltages are used in this equipment.
Use extreme caution when carrying out
electrical checks. Isolate the power supply
before starting any maintenance work.
7. During the initial starting period, the drive
motor starts in Star connection. Following the
switch from Star to Delta a two seconds load
delay time will occur before the compressor
runs on load. The compressor will load and
unload according to the delivery pressure set
points P1 and P2.
Note: When the compressor is on-load, a small
light will appear in the lower left hand side of the
display to indicate the compressor is in the loaded
condition. This is intended as a fault diagnostic aid
only.
8. Initially the oil temperature will rise rapidly to
working temperature, the thermostatic bypass
valve will then operate to maintain the
temperature at normal working level.
9. Fault conditions are continuously monitored
from start-up and an alarm or trip indicator
will flash if a fault occurs.
10. To interrogate the Oil temperature or to view
the Hours Run press VIEW (B1). See para
1.5 'Oil temperature and Hours run display'.
1.2

Standby Mode

1. If the compressor is off-load for longer than
the programmed 'Run-on time', the
compressor will stop and the 'Start' indicator
(L8) will flash slowly for a short period of time
while the compressor blows down.
2. The Start indicator will flash quickly to
indicate the compressor is in the Standby
mode. The compressor will start
automatically when the delivery pressure falls
below the P2 pressure set point.
