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 network pressure
The compressor is controlled using an electronic
pressure switch. In the
[
CONTROL
MENU
]
menu you
have to set the minimum network pressure switching
point (
CUT-IN
POINT
) and the maximum network
pressure switching point (
CUT-OUT
POINT
).
When the maximum network pressure switching point is
reached, the machine switches to off-load.
The minimum network pressure switching point then
specifies when the machine is switched back into on-
load.
Example:
CUT-OUT
POINT 10.0bar
CUT-IN
POINT
9.8bar
When the network pressure reaches 10.0 bar, the
machine switches to off-load.
If the network pressure then falls to 9.8 bar, the
machine is switched back into on-load.
Max. network pressure:
The network 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 network pressure
CUT-
OUT
POINT
must be at least 0.2 more than the
minimum network pressure
CUT-IN
POINT.
You may
therefore have to first set the minimum network
pressure point. To prevent your compressor suffering
from excess wear, the difference between the
CUT-
OUT
POINT
and
CUT-IN
POINT
should not be too
small.
Min. network pressure:
In the
[
CONTROL
MENU
]
sub-menu please use
to go to the
CUT-IN
POINT
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 DELCOS
Pro
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.
