2.1 Selecting language
You can change the language by pressing the +
or +
keys. Press these keys at the same time until
the right language appears.
2.2 Setting line pressure
Speed is controlled with the aid of a PI controller
implemented in the software and is matched to the
demand for compressed air. In the
[
CONTROL
MENU
]
menu you have to set the maximum line pressure
switching point (
CUT-OUT
POINT
) and the
TARGET
PRESSURE
.
When the maximum line pressure switching point is
reached, the machine switches to off-load.
In the range between
TARGET PRESSURE
and
CUT-
OUT
POINT
the speed of the machine is regulated
according to the compressed air requirement.
Example:
CUT-OUT
POINT
10.0bar
TARGET PRESSURE
9.5bar
The speed of the machine is regulated according to the
need for compressed air so that the set pressure of
9.5 bar is maintained.
When the line pressure reaches 10.0 bar, the machine
switches to off-load.
Max. line pressure:
The max. line pressure is set in the
[
CONTROL
MENU
]
-
sub-menu. The
+
keys have to be pressed at the
same time to do this. You are then taken to the main
menu. Use
to switch to the
[
CONTROL
MENU
]
sub-
menu. Then please press the key.
The
CUT-OUT
POINT
menu item now appears on the
display. Again pressing the
–
key causes the value to
flash. You can now correct (increase or decrease) this
value using
or
. Then confirm the value set by
pressing the key.
Note
The control system checks whether the value set can
be used. The maximum line pressure
CUT-
OUT
POINT
must be at least 0.2 more than the
TARGET PRESSURE.
You may therefore have to first
set the
TARGET PRESSURE
. To prevent your
compressor suffering from excess wear, the difference
between the
CUT-OUT
POINT
and
TARGET
PRESSURE
should not be too small.
Target pressure:
In the
[
CONTROL
MENU
]
sub-menu please use
to go to the
TARGET PRESSURE
menu item.
Pressing the key causes the value to flash.
You can now correct (increase or decrease) this value
using
or
. Then confirm the value set by pressing
the key.

2.3 Setting time/date (timer)
The GD Pilot accumulator can bridge a loss of power -
lasting between around two to three weeks. If power is
lost for longer periods, the timer's time and date are lost
and have to be entered anew.
Press the
+
keys at the same time. Use
to go
to the
[
TIMER
CONTROL
]
sub-menu and press the
key. The date and time are displayed there in the
following format:
TU 30.10.07 12:10:34
If you press the key, the left-hand value (day of the
week) starts to flash. You can now use the
or
keys to set this. Then confirm the value by pressing the
key.
All values can now be set in succession using this
procedure. When the last value (seconds) has been
set, the timer is fully set and you can exit the menu by
twice pressing the
+
keys at the same time.
