6.1 Limit contacts
Risk of electric shock from exposed live
parts.
Do not touch live parts on adjusting the limit
contacts.
The limit contacts (6, Fig. 1) can optionally
be used as make or break contacts.
Terminal assignment (Fig. 6):
−
Terminals 41, 44, 42:
à
Bottom cam disk, adjuster 7.1
−
Terminals 51, 54, 52:
à
Top cam disk, adjuster 7.2
1. Unscrew front cover.
2. Move the actuator stem to the position at
which switching point is to be activated.
3. Use a 4 mm Allen key to turn the adjust-
ers (7.1 or 7.2 in Fig. 1) up to the point
where the contact is triggered.
The angle of rotation of the cam disks is lim-
ited. Therefore, use preferably the top adjust-
er (7.1) for the upper travel range and the
bottom adjuster (7.2) for the lower travel
range.
6.2 Resistance transmitters
As the valve passes through its travel range,
the resistance value changes from 0 Ω to ap-
prox. 80 % of its nominal value. Turn a
screwdriver placed on the slotted shaft to
calibrate the resistance transmitter.
Calibrating the actuator with an extended
actuator stem at 0 Ω
1. Connect ohmmeter to terminals 61 and
62 (see Fig. 6).
2. Extend the actuator stem to its end posi-
tion.
3. Turn the resistance transmitter counter-
clockwise as far as it will go. The ohm-
meter indicates the initial value of ap-
prox. 0 Ω.
Calibrating the actuator with a retracted
actuator stem at 0 Ω
1. Connect ohmmeter to terminals 61 and
63 (see Fig. 6).
2. Retract the actuator stem to its end posi-
tion.
3. Turn the resistance transmitter clockwise
as far as it will go. The ohmmeter indi-
cates the initial value of approx. 0 Ω.
4. Only for actuators with 6 or 12 mm
travel: Slowly turn the resistance trans-
mitter counterclockwise up to the point
where the resistance changes from 0 Ω.
