4.4 Positioner (for 4 - 20 mA or 2 - 10 Vdc signals)
1. A 1000 ohm precision potentiometer must be installed in the actuator (Section 3.5.2).
2. Fit the positioner card (Section 3.4). Insert the contact pins into the left side of the terminal
strip, engage the board into the retaining pegs. Tighten the terminal screws.
3. Connect up the actuating signal according to the required signal range at the top right
(4 - 20 mA or 2 - 10 V), see Section 3.6.2. Set multimeter to 10 Vdc and connect test leads
into the terminal points 'GND' and 'U out' of the positioner card. Connect mains supply to the
mains terminals at the lower right side of the positioner card. Connect the protection earth of
the mains supply to the 'PE' point of the actuator housing.
WARNING
The AEL5961 and AEL5962 positioners use parts supplied with mains voltage (terminal
points, fuses etc). These parts are covered but all adjustments should be made using
an insulated screwdriver held at the grip.
