    1 Application

    IC 20

    IC 30

    IC 50

    The actuators are designed for all applications that require precise, controlled rotary movement between 0° and 90°. In conjunction with a control element, they are suitable for regulating flow rates on gas and air appliances for modulating-controlled or stage-controlled combustion processes.

    In addition to setting the min. and max. positions using infinitely adjustable switching cams, floating limit switches mean that additional switching positions such as for ignition and high-fire rate positions can be set.

    A standard Service switch allows the device to be switched from Automatic to Manual mode and a position indicator which can be read from the outside drastically simplifies the commissioning procedure.

    IC 20, IC 30 and IC 50 are controlled by a three-point step signal. IC 20..E and IC 50..E can also be controlled by a continuous signal.

    IC 30 is suitable for 24 V DC applications.

    An integrated feedback potentiometer offers the option of monitoring the current position of the actuator. This checking function can be used in automation processes.

    IC 20..E, IC 50..E

    The behaviour of the actuator, e.g. if the input signal falls below the minimum limit in the event of cable discontinuity, can be set using DIP switches.

    Fluctuations or interference in the input signal are suppressed by an adjustable potentiometer. In the case of continuous control, the input signal can be adapted to the minimum and maximum adjustment angles manually or automatically. This calibration process can be visualized using LEDs. The continuous signal offers the option of monitoring the current position of the actuator.

    1.4 Application examples

    1.4.1 Modulating control via three-point step signal

    For processes that require high temperature accuracy and low circulation in the furnace. Actuator IC is controlled by a three-point step controller and moves the butterfly valve to the ignition position. The burner starts. The butterfly valve opens or closes between the low-fire/high-fire rate positions depending on the capacity demand of the burner. When the three-point step signal is disconnected, the butterfly valve stops at its current position.

    For processes that require high control accuracy. The low-fire and high-fire rates are adjusted using the control element upstream of the burner. Actuator IC 30 is controlled by a three-point step controller and ensures the desired gas/air mixture is produced.

    1.4.2 Staged control via two-point step signal

    For processes that require a homogeneous temperature distribution in the furnace. Actuator IC..E is controlled by a two-point step controller and operates in On/Off or High/Low intermittent mode. The actuator closes when the voltage is disconnected.

    1.4.3 Modulating control with continuous input signal

    For processes that require high temperature accuracy and low circulation in the furnace. Actuator IC..E is controlled by a (0)4–20 mA or 0–10 V signal.

    1.4.4 IC 20, modulating control with burner control unit BCU

    The BCU moves the butterfly valve to pre-purge and ignition positions. After pre-purge and burner start, the controller enable signal is issued to an external three-point step controller which positions the butterfly valve in accordance with the capacity demand.

    Once the pre-purge or ignition position has been reached, a feedback signal is sent to the BCU.

    1.4.5 IC 20..E, continuous control with burner control unit BCU

    3 Function

    The actuator moves towards 0° or 90° if it is energized electrically at the related terminal. If the voltage is disconnected, the actuator stops in its current position. A high holding torque when de-energized renders additional braking elements superfluous. The low-fire and high-fire rates are adjusted using infinitely adjustable switching cams. An integrated feedback potentiometer (optional on IC 20, IC 30) makes it possible to monitor the current position of the actuator.

    Automatic/Manual mode

    Switchover between Automatic and Manual mode facilitates setting of the infinitely adjustable switching cams during commissioning. This enables precise settings even in the low-fire rate range.

    The switching point is set directly on the cams.

    External devices can be activated or intermediate positions can be checked via additional, floating, infinitely adjustable switches. The IC 30 has one adjustable switching cam, the IC 20 has two and the IC 50 has three.

    Three-point step control

    In the case of default setting “Closed”: The control element opens until switch S3 trips when voltage is applied to terminal 2. The control element closes until S4 trips when voltage is applied to terminal 1, see Project planning information.

    3.2 IC 20..E, IC 50..E connection diagram

    In normal operation, input “OK” is supplied with voltage. The setpoint device issues an actuating signal
    (0 (4)–20 mA, 0–10 V). The continuous signal corresponds to the adjustment angle to be approached (e.g. with a 0 to 20 mA signal, 10 mA correspond to a valve angle of 45°).

    Continuous control

    Following successful modulation enable via terminal 5 (OK), the actuator reacts to the setpoint specification (0 (4)–20 mA, 0–10 V) via terminals 17 and 18.

    The IC..E offers the option of monitoring the current position of the actuator via terminals 19 and 20, see Project planning information.

    Three-point step control

    No voltage at terminal 5. Voltage must be applied to terminals 3 and 4 continuously.

    Two-point step control must be deactivated at the DIP switch.

    Two-point step control

    Connect voltage to terminals 1 and 3. Set the DIP switches to 2-point step control. If an input signal is applied to terminal 5 (OK), the actuator opens. If no input signal is applied to terminal 5, the actuator closes.

    4.3 Butterfly valve torque, actuator running time

    The characteristic curves relate to the maximum torque produced by the flow rate. In general, maximum torque is reached at approx. 70°.

    The running time of the actuator per 90° depends on the required torque.

    The running time is reduced by a factor of 0.83 at a frequency of 60 Hz on the actuator.

    4.4 IC 20, IC 30, IC 50 position feedback

    A feedback potentiometer offers the option of monitoring the current position of the actuator.

    In the case of actuator IC 30, IC 50, the feedback potentiometer is included in the delivery. In the case of actuator IC 20, the feedback potentiometer can be retrofitted, see Potentiometer installation set.

    It must be utilized as a voltage divider.

    The change in position of the potentiometer wiper (which corresponds to the actuator position) can be measured as a changing voltage between UM and U-.

    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.

    IC 30: once the switching cams have been adjusted, the potentiometer automatically adjusts itself to the setting travel via the integrated slip clutch.

    IC 20..E, IC 50..E

    The IC..E offers the option of monitoring the current position of the actuator via the continuous 4–20 mA output signal (terminals 19 and 20).

    Position feedback at terminals 15 and 16: interference suppression capacitors installed in the system must only be used in conjunction with a series resistor so as not to exceed the maximum switch-on current – see Technical data.

    4.5 IC 20..E, IC 50..E, continuous control: adapting the input signal to the adjustment angle

    The continuous signal corresponds to the adjustment angle to be approached (e.g. with a 0 to 20 mA signal, 10 mA correspond to a valve angle of 45°).

    Automatic calibration

    If the factory setting is changed, the mA signal for the minimum and maximum opening angles must be confirmed via automatic calibration. The setpoint specification will then correspond to the setting of switching cams S3 and S4.

    Manual calibration

    If the mA signal is to be used for modulation between the minimum and maximum opening angles, the signal is set via manual calibration.

    Characteristic curve inversion

    If 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).

    5 Project planning information

    5.1 Installation

    Installation position

    IC 20, IC 50:
    vertical or horizontal, not upside down.

    IC 30 with VFC:
    as required; IC 30 with BVA/BVG: not upside down.

    If the actuator is used with hot air, the pipeline should be adequately insulated so as to reduce the ambient temperature. In order to avoid overheating, the flanges and butterfly valve must not be insulated.

    Use heat deflectors for a medium temperature of > 250°C, see IC 20, Heat deflector, and IC 50, Heat deflector.

    IC 20

    In order to mount actuator IC 20 onto control elements other than DKL, DKG, BVA, BVAF, BVG, BVGF, BVH, BVHS or VFC, the attachment set for “single application” is required, see “Single application” attachment set.

    IC 30

    In order to mount actuator IC 30 onto linear flow control VFC, an adapter set is required, see Adapter set IC 30 or Adapter set IC 30 for BVA/BVG.

    IC 50

    Actuator IC 50 can be mounted directly onto a wall using a bracket, see Wall mounting bracket.

    Attachment sets are available for mounting to butterfly valve DKR, see Attachment sets.

    5.2 Cable selection

    Install supply and signal lines separately.

    Cables should be installed well away from high-voltage lines of other devices.

    IC 30: feedback potentiometer lines should be equipped with additional shielding.

    Observe EMC Directive for installation of signal lines.

    Use cables with wire end ferrules.

    Cable cross-section: max. 2.5 mm².

    Conductors which have not been connected (spare conductors) must be insulated at their ends.

    CSA requires temperature-resistant cables (≥ 90°C).

    5.3 Electrical connection

    IC 20, IC 50: running times are reduced by a factor of 0.83 at 60 Hz compared to 50 Hz.

    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 maximum current – see Technical data.

    IC 20..E, IC 50..E: three-point step control

    When no voltage is applied to terminal 5, three-point step control is active. Two-point step control must be switched off at the DIP switch.

    5.4 IC 50, IC 50..E: changing the direction of rotation

    The function of switching cams S3/S4 changes if the direction of rotation ccw/cw (anticlockwise/clockwise) is modified. The actuator is set to ccw at the factory.

    ccw: S3 = maximum angle, S4 = minimum angle.
    cw: S3 = minimum angle, S4 = maximum angle.

    IC 50..E

    When changing the direction of rotation, both DIP switch 7 and switch S12 must be in the same position (cw/ccw).

    5.5 IC 20..E, IC 50..E, continuous control: adapting the input signal to the adjustment angle

    The continuous signal corresponds to the adjustment angle to be approached (e.g. with a 0 to 20 mA signal, 10 mA correspond to a valve angle of 45°).

    Automatic calibration

    If the factory setting is changed, the mA signal for the minimum and maximum opening angles must be confirmed via automatic calibration. The setpoint specification will then correspond to the setting of switching cams S3 and S4.

    Manual calibration

    If the mA signal is to be used for modulation between the minimum and maximum opening angles, the signal is set via manual calibration.

    Characteristic curve inversion

    If 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).

    5.6 Using the IC 50 to replace the GT 50

    If a GT 50 is upgraded to an IC 50, it must be noted that the feedback potentiometers on both actuators have different adjustment ranges. IC 50: 0–90°

    The zero positions may differ from each other.
