Manual calibration
▷ The minimum and maximum opening angle can
be anywhere within the range set using switching
cams S3 andS4.
 Move the valve to the required min. position by
pressing toggle switchS11.
 Press the min button (approx. 3seconds) until the
blue LED goes out briefly (approx. 0.5seconds).
 Move the valve to the required max. position by
pressing toggle switchS11.
4 Press the max button (approx. 3seconds) until
the blue LED goes out briefly (approx. 0.5sec-
onds).
Characteristic curve inversion
▷ The mA value for low fire has to be greater than
the mA value for high fire.
 Press the min or max button until the red LED
lights up briefly (approx. 0.5 seconds) and hold
it in for approx. 3 seconds more until the blue
LED goes out briefly (approx. 0.5 seconds).
Changing the direction of rotation
IC 50
▷ The direction of rotation is defined using slide
switchS12.
▷ cw (blue mark on the cover) = valve opens
clockwise,
ccw (white mark) = valve opens anti-clockwise.
IC 50..E
▷
The direction of rotation is defined using DIP
switch7 and slide switchS12.
IC 50, IC 50..E
▷ When changing the direction of rotation, these
two switches must be set to the same position:
cw (blue mark on the cover) and ccw (whitemark).
▷ The function of switching cams S3/S4 changes
if the direction of rotation (ccw/cw) is modified,
see page6 (Commissioning).
Accessories
Wall mounting bracket
The wall mounting bracket is required if the actuator
is to be attached to a wall.

Maintenance
Actuators IC 50 suffer little wear and require little ser-
vicing. We recommend a function check once a year.
Assistance in the event of
malfunction
WARNING
To avoid harm to persons and damage to the unit,
please observe the following:
– Electric shocks can be fatal! Before working
on possible live components, ensure the unit
is disconnected from the power supply.
– Never remove the circuit board!
– Unauthorized repairs or incorrect electrical con-
nections may cause the butterfly valve to open
resulting in defects.
? Fault
! Cause
• Remedy
? The valve disc does not move.
! The actuator is in Manual mode (IC50..E: blue
LED is lit).
• Set slide switch S10 to Automatic mode.
! No voltage at terminal 5.
• Check voltage at terminal 5.
! Motor coil or electronics defective as a result of
excessive ambient temperature and/or excessive
operating voltage.
• Check ambient temperature and/or operating
voltage, see type label or page8 (Technical
data).
! Cam trip points maladjusted. S4 has been set to
a wider angle than S3 (IC50..E: red LED lights
up, blue LED flashes 1×, if the unit has been
automatically calibrated).
• Adjust the trip points, see page6 (Commis-
sioning). Then calibrate the IC50..E.
! Electrical fault!
