Configuration 5
October 2013 GB 27 /80
If the line pressure reaches the lower pressure
value of 9.5 bar(Pressure Demand), the suction
regulator opens and the compressor switches on-
load so that it is again supplying compressed air.

compressors (FS)
1
Tap the <Settings> tab.
–
The menu "Settings" appears.
2
Tap the <Control...> button.
–
The menu "Control" appears.
3
Tap the button <p1 Cut-In Point>.
–
The input menu "p1 Cut-In Point" appears.
4 Tap the <Number buttons> to enter the pres-
sure value.
The <Cancel> button can be used to cancel
setting of the pressure value. The previously
active pressure value is used.
5
Tap the <OK> button.
– The set pressure value is saved.
– The display reverts to the previous menu,
"Control".
6
Tap the button <p1 Cut-Out Point>.
–
The input menu "p1 Cut-Out Point" ap-
pears.
7 Tap the <Number buttons> to enter the pres-
sure value.
The <Cancel> button can be used to cancel
setting of the pressure value. The previously
active pressure value is used.
8
Tap the <OK> button.
– The set pressure value is saved.
– The display reverts to the previous menu,
"Control".
✓ The pressure band p1 is set.
Setting pressure band p2 for fixed speed
compressors (FS)
Setting of pressure band p2 takes place as previ-
ously described, the sole difference is that the p2
buttons must be tapped rather than the p1 buttons.
Specifying the source for pressure band con-
trol
The source for pressure band control can be
changed via p2 timer control operation as well as
via the programmable inputs. See chapter "Con-
figuration / Timer Control Operation" and chapter
"Configuration / Inputs and Outputs".
5.5.2 Programming Inputs and Outputs
NOTICE
Material damage
➯
Only potential-free contacts may be con-
nected to the terminal strip.
External voltages result in destruction of the
controller.
➯
The potential-free contacts must not be
more than 20 metres away from the termi-
nal strip.
If necessary, coupling relays must be fitted
in the switch cabinet.
5.5.2.1 Programmable Inputs
The controller has programmable inputs. The
number of inputs may vary depending on the com-
pressor configuration. See wiring diagram.
NOTE
Programmable inputs may already be occu-
pied by pre-installed accessories and/or optional
equipment. Which inputs are free can be deter-
mined using the supplied wiring diagram.
If monitoring equipment has been pre-installed
and connected to programmable inputs, you
must not change the corresponding settings, as
doing so would disable the monitoring equip-
ment.
Inputs can be assigned to
monitor conditions or devices when the con-
tacts on the appropriate terminals are opened.
to activate functions when the contacts on the
appropriate terminals are closed.
