Configuration switches for the analogue control signal
Voltage or current signal
This slide switch
Y
can be used to select a 0 to 10 V voltage signal
or a 4 to 20 mA current signal. The setting applies to both the control
signal input and output.
Invert control signal
This slide switch inverts the analogue control signal (input and
output).
Switch up:
Inverted: 0V or 4mA = driving spindle retracted
Switch down
:
Normal: 0V or 4mA = driving spindle extended
Fail-safe behaviour in
case of control signal
failure
In case of a control signal failure (control signal <3.6 mA) or a cable
break (0-10 V and 4-20 mA) the set position is approached:
·
End position UP
·
STOP
·
End position DOWN
Force off
The
Force
switch specifies the direction in which the actuator is
switched off by the thrust in the final position.
- Switch up: Retracting spindle
- Mid-position: Both directions
- Switch down: Extending spindle
The tight closing function is active in the set final position(s) to
ensure that the valve is closed with the nominal actuator force.
The function is activated within a capture range equivalent to 4% of
the travel upstream of the Force switch, causing the actuator to be
moved into the "Thrust off" position. It does not leave this position
until the analogue control signal exceeds the 4% threshold again.
If the Force switch for a final position is not activated by the
parameter switch, the actuator is switched off in the final position
according to the travel.
