Description
"Input type"
"Analog"/"Digital"
Appears only for voltage variants. For current vari-
ants, "Input type" = "Analog".
–
"Analog": An analogue voltage / current value
via setpoint value (+) and setpoint value (-)
determines the setpoint pressure.
–
"Digital": One of 8 setpoint values is specified
via three digital 24 V inputs. For this, the three
inputs are interpreted as a binary number with
3 bit.
The assignment is as follows:
–
Setpoint value (+): DI0 or least significant bit
–
Setpoint value (-): DI1
–
Actual value output: DI2 or most significant bit
The value 000 means 0 bar and cannot be edited;
the remaining 7 values can be set in "Input values".
There is no actual value output in this mode.
"Input unit"
[V/mA/]/[bar/kPa/psi]/
%
Appears only if "Input type" ="Analog."
Determines the unit in which the setpoint value is
displayed on the main screen.
"Input max"
E.g. 5 V
Appears only if "Input type" = "Analog".
Upper limit of the analogue setpoint value range
"Input min"
E.g. 0 V
Appears only if "Input type" = "Analog".
Lower limit of the analogue setpoint value range
"Ramp-up-time"
"Off"/X ms
X=
75/125/250/500/
750/1000/1500/
2000
Setpoint jumps upwards are filtered with a low-pass
filter. The set value is the time constant (tau) in milli-
seconds.
"Ramp-down-time" "Off"/X ms
X=
75/125/250/500/
750/1000/1500/
2000
Setpoint jumps downwards are filtered with a low-
pass filter. The set value is the time constant (tau) in
milliseconds.
