Interface/switched outputs
Sensor Calibration input Power 230VAC, 115 VAC
a good earth point having a large surface area
for minimum impedance.
The unit should be positioned well away from
cables with interference; if necessary
a protective
screen or metal housing must be provided . The
running of wiring parallel to the mains supply
should be avoided.
Contactor coils must be linked with spark sup-
pression.
PE-connection with 2,5 – 4mm² via PE-clamp (fig. 2).
Power supply
is made via mains connection on rear of the de-
vice. The correct supply voltage is indicated in
the delivery documentation:
eg.: 230 VAC ±10%
Sensor connection
via 8-poles rear side Mini-Din socket (fig. 2/fig. 6).
Attention!
No modifiction of the sensor connec-
tion, eg. by cable extension, is permitted.

4.1.1 Optional serial RS232 or RS485 interface
The RS232 or RS485 serial interfaces are connec-
ted via terminals 3 (GND), 6 (TXD/ DÜA) and 5
(RXD/ DÜB).

4.1.2 Switching output option
Two open collector outputs A1 (terminal 6) and
A2 (terminal 5) are available. The common nega-
tive pole of these outputs should be connected to
terminal 3. The admissible voltage range is 30VDC,
the admissible maximum current 10mA per out-
put. The switching behaviour of these outputs is
programmable.
Position value > upper limiting value (UPL): actuator 1 active
