7.6 Position Signalization

Description
Position
signalization
The position signalization enables determining the exact
mechanical position of a valve. Output signal is a current of
4 – 20 mA. (4mA-CLOSED, 20mA-OPEN).
The position signalization can be combined with the positi-
oner or the monitoring print.
The position signalization board is mounted on the limit
switches S1, S2 and is connected electrically to the positio-
ner or the monitoring print via a system cable.
Mounting the position signalization
1. Disconnect the actuator from the supply voltage.
2. Remove the screws of the limit switches S1 and S2.
3. Remove the position indicator (1).
4. Place the position signalization board in the position
shown on S1 and S2 and fasten with the longer screws.
5. Insert the toric magnet (3) so that the notches are on the
top.
Again place the position indicator (1) on the axis in one of
the end positions.
6. Connect the position signalization board to the control-
ler or monitoring print via the system cable (2).
Reconnect to the power supply.
The board has been connected correctly when the LED
(4) lights up green.
If the position signalization is used
together with additional limit switches,
the position signalization as to be in
stalled above the limit switches.
