Checking the usage
Intended use
Actuator IC 50
It is designed for all applications that require precise,
controlled rotary movement between 0° and 90°. If
the voltage is disconnected, the actuator stops at
the current position.
The combination of actuator IC50 and butterfly valve
DKR is designed to adjust volumes of hot air and
flue gas on various appliances and flue gas lines.
This function is only guaranteed when used within the
specified limits– see page8 (Technical data). Any
other use is considered as non-compliant.
For information on butterfly valves DKR, see DKR
operating instructions→www.docuthek.com→

terfly valves.

Installation
CAUTION
Please observe the following to ensure that the
actuator is not damaged:
– Do not store or install the unit in the open air.
– Dropping the device can cause permanent dam-
age. In this event, replace the entire device and
associated modules before use.
▷Installation in the vertical or horizontal position,
not upside down.
▷ For the assembly of actuator with butterfly valve
and attachment sets, and for installation in a pipe,
see DKR operating instructions.

▷ Do not insulate the actuator with thermal insu-
lation.
Wiring
WARNING
Electric shocks can be fatal!
–Before working on possible live components,
ensure the unit is disconnected from the power
supply.
–It must be possible to isolate the actuator from
the power supply. Provide a double pole switch.
▷Use temperature-resistant cables (≥ 90°C).
▷Install supply and signal lines separately.
▷Cables should be installed well away from high-
voltage lines of other devices.
▷Observe EMC Directive for installation of signal
lines.
▷ Conductors which have not been connected
(spare conductors) must be insulated at their
ends.
▷Use cables with wire end ferrules.
▷Cable cross-section: max. 2.5mm².
▷ When operating two or more actuators in parallel,
the three-point step controller (terminals 1 and2)
must be electrically isolated to avoid leakage
currents. We recommend using relays.
▷Interference suppression capacitors installed in
the system must only be used in conjunction with
a series resistor so as not to exceed the maxi-
mum current– see page8 (Technical data).
▷Running times are reduced by a factor of 0.83
at 60 Hz compared to 50 Hz.
▷ External devices can be activated or intermediate
positions can be checked via three additional,
floating, infinitely adjustable switches (cams S1,
S2 andS5).
▷The input signals for the actuator can be set via
DIP switches. DIP switch positions that are not
indicated can be freely selected, see connection
diagram, page5 (IC 50..E).
 Disconnect the system from the electrical power
supply.
 Shut off the gas supply.
▷ Before opening the unit, the fitter should ground
himself.

▷Voltage is applied to terminals 3 and4.
Three-point step control
▷In the case of default setting “Closed”:
The butterfly valve opens when voltage is applied
to terminal2.
The butterfly valve closes when voltage is applied
to terminal1.
▷ Terminals 6 to 13 must be operated with the
same voltage potential.
Feedback
▷
A feedback potentiometer offers the option of
monitoring the current position of the actuator.
▷The potentiometer must be utilized as a voltage
divider. The change in position of the potentiom-
eter wiper (which corresponds to the actuator
position) can be measured as a changing voltage
between U-and UM.
▷ Other circuit layouts produce measurement
results that are inaccurate and do not remain
stable over a long period of time or are non-
reproducible. They also reduce the service life
of the feedback potentiometer.
▷The available range depends on the adjustment
of switching cams S3 andS4.

▷The actuator reacts to the setpoint specification
(0(4)–20mA, 0–10V) via terminals 17 and18.
▷ The continuous signal corresponds to the ad-
justment angle to be approached (e.g. with a 0
to 20mA signal, 10mA correspond to a valve
angle of45°).
Feedback
▷Terminals 19 and 20: the IC 50..E offers the op-
tion of monitoring the current position of the ac-
tuator via the continuous 4–20mA output signal.
Input signal
▷The positioning control hysteresis can be adjust-
ed on a potentiometer to suppress fluctuations
or interference in the input signal.
▷The hysteresis can be increased accordingly by
turning the potentiometer clockwise.

switchS12.
▷ cw (blue mark on the cover) = valve opens
clockwise,
ccw (white mark) = valve opens anti-clockwise.

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).
