3.1 Starting the unit
Danger
If the unit is ready, i.e. the green LED is flashing,
the compressor may automatically start at any time.
Use the main switch to switch the unit on.
If warning or fault messages appear in the third row of
the display, these first have to be rectified and
confirmed using the key.
Then start the unit by pressing the

I
key on the GD
Pilot.
3.2 Emergency off button
The EMERGENCY-stop button is situated next to the
GD Pilot. It is used to immediately shut down the unit.
Only use the emergency off button to shut down the
unit in emergencies. When shutting down normally,
always use the


key.
3.3 Switching off the unit
The unit is switched off by pressing the


key on the
GD Pilot. However the unit will only stop after a 30-
second soft-stop.
The soft-stop is preset to protect the compressor.
Note
The unit may only be shut down using the emergency
off button in real emergencies. When shutting down
normally, please use the


key.
3.4 On-load/off-load
Descriptions of the CONTINUOUS OPERATION and
AUTOMATIC OPERATION
modes can be found in
section 5.1.1.
OFF-LOAD:
If there is no line pressure requirement from the
compressed air system and the unit is in
CONTINUOUS OPERATION
, it switches to
OFF-LOAD
.
This means that the motor and compressor stage run
but no air is pumped into the compressed air system.
The unit behaves differently if in AUTOMATIC OPERATION
mode. If there is no line pressure requirement, the
compressor switches to OFF-LOAD. The unit is switched
off after a run-on time that is shown on the display. If there
is another pressure requirement during the run-on time,
the unit is automatically switched on.
ON-LOAD:
If the unit is in
ON-LOAD
, air is pumped into the
compressed air system.
3.5 Acknowledging warning/fault
messages
Warning and fault messages are shown in the third row
of the display. The red light signal flashes at the same
time.
You will find a table containing the messages and -
suggestions for how to remedy them in section 6.5.
3.5.1 Warning messages
When there are warnings, the red light signal flashes
slowly. The unit does not automatically shut down when
there are warnings. However ignored warnings may
cause faults.
Rectify what is causing the warning and press the
key to hide the warning.
3.5.2 Fault messages
Fault messages result in the unit automatically shutting
down or do not permit the unit to be started.
Once you have rectified the problem, you still have to
confirm by pressing the key.
