Intended use
Actuator IC 0
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20 and control ele-
ment is designed to adjust volumes of gas and air
on various appliances and flue gas lines.
IC20 and butterfly valve BV..(IB..) are designed for
control ratios of up to 10:1 for gas, cold and hot air
and flue gas.
IC20 and linear flow control VFC(IFC) are designed
for control ratios of up to 25:1 for gas and cold air.
This function is only guaranteed when used within the
specified limits– see page8 (Technical data). Any
other use is considered as non-compliant.

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.
– Do not insulate the actuator with thermal insula-
tion.
▷Installation in the vertical or horizontal position,
not upside down.
▷ For further information on assembly of the IC20
with butterfly valveBV.. or linear flow controlVFC,
see enclosed operating instructions.
Otherwise go to www.docuthek.com, Elster
Thermal Solutions→Products→03Valves

or →Linear flow controls IFC,VFC.
▷ An adapter set is required for mounting onto
butterfly valve DKL, DKG, see page 6 (Ac-
cessories).
▷ If the actuator is to be mounted onto control
elements other than DKL, DKG, BV.. or VFC, the
“Single application” attachment set is required,
see page6 (Accessories).
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.
▷Install supply and signal lines separately.
▷ Conductors which have not been connected
(spare conductors) must be insulated at their
ends.
▷Cables should be installed well away from high-
voltage lines of other devices.
▷Observe EMC Directive for installation of signal
lines.
▷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 intermedi-
ate positions can be checked via two additional,
floating, infinitely adjustable switches (cams S1
andS2).
▷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4 (IC 20..E).
 Disconnect the system from the electrical power
supply.
 Shut off the gas supply.
▷ Before opening the unit, the fitter should ground
himself.

Three-point step control
▷In the case of default setting “Closed”:
The control element opens when voltage is ap-
plied to terminal2.
The control element closes when voltage is ap-
plied to terminal1.
▷ Terminals 6 to 13 must be operated with the
same voltage potential.
Feedback
▷ An optional feedback potentiometer offers the
option of monitoring the current position of the
actuator IC20, see page6 (Accessories).
▷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.

Three-point step control
▷ No voltage at terminal 5: three-point step control.
▷ Voltage must be applied to terminals 3 and4
continuously.
▷ The low-fire rate (CLOSED) and the high-fire rate
(OPEN) are controlled via terminals 1 and2.
Two-point step control
• Connect bridge between terminals 1 and3.
• Set the DIP switches to 2-point step control.
▷ When voltage is applied to terminal5, the ac-
tuator opens.
When no voltage is applied to terminal5, the
actuator closes.
▷Terminals 17 and 18 for continuous control are
not required in the case of 2-point control.
Continuous control
▷Voltage at terminal 5: continuous control.
▷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 20..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.
Commissioning
▷The maximum opening angle can be set using
switching camS3 and the minimum opening
angle can be set usingS4.
▷ Switching cams S1/S2 can be optionally ad-
justed.
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.
