Seven timer units are again available here for the
setting (programming). The values that you have set for
the second pressure range supersede the values for
CUT-OUT
POINT
and
CUT-IN
POINT
as soon as a
switching unit is active. The 1st row on the display then
shows the
p
2
symbol in front of the final compression
temperature. If the switching unit becomes inactive, the
values for
CUT-OUT
POINT
and
CUT-IN
POINT
are
again used.
The status line of each switching unit is as follows:
a)
b)

a) 2nd pressure range
b) Unit no.
c) Days of the week [

d) Switch-in point
e) Switch-out point
When the
is pressed, the first underscore _ starts to
flash. You can now use the
key to set the first day of
the week (Sunday). Then use the
key to confirm the
day of the week. The next underscore _ now flashes. If
you do not want to confirm a day of the week as set,
immediately press
.
You can run through all seven
days of the week in this way. Once you have confirmed
the last day of the week (Saturday), the first unit of the
switch-in point starts to flash. You can either set this
using
or
. Once the last unit of the switch-out
point has been confirmed, the whole switching unit is
activated.
Go to the
[

value starts to flash. You can now
use the
key to change the value to
ON
. Then please
press the
key again to confirm the entry. The timer is
now switched on for the second pressure range. Please
refer to section 5.1.2 for how to set the parameters for
the 2nd pressure range.

Note
The values shown are examples only. The limit values
in your unit may be different.
a) This is your unit's operating pressure. This is also
stamped on the compressor's name plate.
b) To protect the compressor stage, the compressor
only starts up when the compressor's internal
pressure is less than or equal to the set value. If the
compressor's internal pressure is higher when
starting up, the following appears in the display's
third row:
WARNING
START
AFTER
...
alternating with
...
DE-PRESSURISE
c) If the internal pressure builds up too quickly when
the compressor starts up, there is an error in the
unit. To protect the motor in the case of an error, the
machine shuts down if pressure builds up too
quickly.
FAULT HEAVY
STARTUP
appears in the
third row on the display.
d) If the final compression temperature reaches
110 °C,
WARNING HIGH

appears in the
display's third row.
e) If the final compression temperature reaches
120 °C, the compressor shuts down.
FAULT

then appears in the third row on the
display
f) If the temperature in the compressor station is
below 1 °C, the machine cannot start up.
g) If the compressor is in automatic mode and there is
no network pressure requirement, the
RUN-

TIME
xxxs
indication appears and the machine
goes into off-load. After the run-on time (
xxx
), the
compressor automatically shuts down and is ready
to start again. If using the timer or the remote start /
stop function, the run-on time is also used.
