▷ The maximum opening angle of the valve can be
set using switching camS3 and the minimum
opening angle can be set usingS4.
▷
Switching cams S1/S2/S5 can be optionally
adjusted.
WARNING
Risk of electric shock due to live components and
cables.
Manual mode facilitates setting
▷
The positions in the low-fire rate range can be
precisely adjusted.
 Set slide switch S10 to Manual mode. The blue
LED lights up.
 Voltage must be continuously applied to the ac-
tuator to allow the valve to open.
 Press the toggle switch S11 upwards.
▷ The valve opens.
4 Press the toggle switch S11 downwards.
▷ The valve closes.
CAUTION
Please observe the following to ensure that the
actuator is not damaged:
– The function of switching cams S3/S4 changes
if the direction of rotation ccw/cw (anti-clock-
wise/clockwise) is modified.
ccw (factory setting):
S3 = maximum angle, S4 = minimum angle.
cw:
S3 = minimum angle, S4 = maximum angle.
▷ The factory setting ccw is described here.
Setting the maximum opening angle using
switching camS(ccw)
▷ Only adjust S3 between 40° and 90°.
▷ Feedback signal to terminal 15.
▷
S3 can only be accessed when the valve is in
an open position.
 Move the actuator to its maximum opening angle.

▷ ccw:
Anti-clockwise = smaller opening angle.
Clockwise = greater opening angle.

Setting the minimum opening angle using
switching camS4(ccw)
▷ Only adjust S4 between 0° and 30°.
▷ Feedback signal to terminal 16.

screwdriver.
▷ The cams can be adjusted over the full angle of
rotation (0–90°) of the actuator.

The IC 50..E is in Manual mode and the blue
LED is lit.
Automatic calibration
▷ The minimum and maximum opening angle cor-
responds to the setting of switching cams S3
andS4 in the case of automatic calibration.
 Press the min and max buttons simultaneously
(approx. 3seconds) until the red(R) and blue(B)
LEDs flash.
▷ Calibration is completed when the blue LED is lit
continuously and the red LED goes out.
