These timer blocks define the periods in which the
machine switches over to the second pressure level.
Switching over to the second pressure range acts on the
current values of CUT-OUT POINT and CUT-IN POINT in
Version FS, and on the current values of CUT- POINT
and TARGET PRESSURE in version RS and SR.
The current values for CUT-OUT POINT and CUT-IN
POINT or TARGET PRESSURE are governed by the
base-load sequencing setting (option in FS and SR
version) in the [BASE LOAD SELECT.] menu.

Timer block active means: system time is within the time
range programmed in the timer block.
The values displayed for CUT-OUT POINT and CUT-IN
POINT or TARGET PRESSURE in Version FS remain
unchanged even while pressure is being switched over.
The procedure for setting pressure changeover time is the
same as that for setting the timer.
If a pressure changeover timer block is active, the p
2
symbol flashes in front of the display of current network
pressure in the top line.
Note
Pressure changeover can also be activated through an
external, floating contact. In FS and RS version, this
takes place through a digital input on the base-load
sequencing module (a dedicated input is available for
this purpose in version SR).
If no pressure changeover is required, deactivate all
pressure-changeover timer blocks.
The menu closes automatically two minutes after last
pressing a key

Changing values
Danger
The machine can start up at any time when
programming in the standby mode.
If the code (see Chapter 1.3.9) is unlocked, all values,
with the exception of [LIMIT VALUES], can be changed
at any time without the code being requested. Using the
and keys, go to the value you wish to change.
Now press the key to enter the input mode. If the
code has still not been unlocked, it will now be
requested. The value flashes when you are in the input
mode.
Note
The and keys are non-operational in the input
mode.
After setting the new value using the and keys, it
must be accepted by pressing the key. Flashing
stops, and a new menu option can be selected.
Using the
key, you can restore the original setting in
the input mode and, at the same time, close the input
mode.
