Application
1 Application
Actuator IC 40 is designed for all applications that require precise, controlled rotary movement between 0°
and 90°. It can be mounted directly onto the butterfly
valves BVG, BVGF, BVA, BVAF, BVH, BVHS or linear flow
control VFC in order to control the gas and air flow rates
on gas burners.
Actuators and butterfly valves or linear flow control
VFC can also be delivered ready assembled as butterfly valves with actuator IBG, IBGF, IBA, IBAF, IBH, IBHS
or linear flow control IFC, see Technical Information
Butterfly valves BVG, BVA, BVH..., IB..., and Linear flow
controls VFC, IFC.
IBG (IC 40 + BVG) IFC (IC 40 + VFC)
An optional integrated feedback potentiometer offers
the option of monitoring the current position of the actuator. This checking function can be used in automation processes.
The IC 40 can be used on continuously-controlled
burners and on stage-controlled burners.
Settings on the actuator IC 40 can be made using a PC
with the programming software BCSoft. All the relevant
settings for the process are made using the software
via an optical interface. Various operating modes, which
may be modified, are stored in the unit. In addition, the
control type (two-point step signal, three-point step
signal or continuous control), running times, adjustment angles and intermediate positions can be programmed.
The actuator can also be controlled “by hand” using the
software.
Once set, all the parameters can be saved on the PC
and copied from there into other actuators, thus saving
time during the commissioning process.
Service technicians can call up statistical data using
BCSoft, such as hours of operation, actuating cycles
and a fault history. Some values can also be set to zero,
for example to record data over a specific period of time.

For processes that require a homogeneous temperature distribution and high temperature accuracy in the
furnace.
If only a low heat output is required, for example to
maintain the temperature in the furnace, the burner can
continue to be operated in intermittent mode. The adjustment angle of the valve is reduced via the analogue
input (4–20 mA) of the actuator and the burner capacity is therefore lowered. This ensures uniform temperature distribution even with a low heat output.
This function of the actuator IC 40 can also be used in
the ceramics industry to correct the lambda value or for
temperature compensation purposes in hot-air applications.

Function
3 Function
The actuator IC 40 moves the butter fly valve towards 0°
or 90°. There are 4 possible positions which the actuator can approach in steps. Any intermediate position is
possible in continuous three-point step mode. Optionally, the actuator can also approach any intermediate
position via an additional current input.
The slow flashing blue LED indicates that the motor of
actuator IC 40 is moving. The position indicator on the
housing indicates the opening angle. Further visualization and operation are performed on a PC using the
BCSoft software.
BCSoft
The sequence of opening and closing is programmed
using the BCSoft software and can be adapted individually to any application.
All settings for the actuator IC 40 are made using
BCSoft. Commissioning and calibration of the “closed”
position are performed conveniently using the software.
BCSoft offers the option of moving and adjusting the
butterfly valve in Manual mode via the actuator, see
page 51 (Manual mode).

Function

3.1 Operating modes
The operating mode is responsible for the setting prop-
erties of the IC 40.
The running times and dwell positions of the actuator
are stored in the various operating modes but can be
reprogrammed at any time using BCSoft (if mounted on
butterfly valve BV..).
The actuator operates in continuous and intermittent
mode with various adjustment angles for the “open”
position. The adjustment angles for the “open” position
indicate the approached position of the actuator in the
case of intermittent operation. They can be changed in
BCSoft.
The corresponding operating modes are displayed in
BCSoft as flowcharts by way of example to visualize the
opening/closing behaviour of the actuator.
3.2 Standard and analogue operating modes
In the standard operating modes, two digital inputs
(DI 1 and DI 2) of the actuator are pre-assigned at the
works as universal inputs. If a voltage of 24 V DC or
100–230 V AC is applied to the input, this is recog-
nized as “On” signal (positive logic). It is not necessary
to set or readjust the voltage magnitude or voltage type.
In the analogue operating modes, an additional input
(IN) is assigned for the actuator. If an actuator IC 40..A
with 4–20 mA analogue input is connected (option),
further operating modes are available in addition to the
standard operating modes. The actuator can approach
corresponding intermediate positions via a current signal to the additional input, see page 49 (Priority and
running time in operating modes 1–10).
3.3
Closed, low-fire rate, intermediate and open
position
Depending on the set operating mode, there are 4 positions which the actuator can approach:
Closed = 0° = 0%,
Low = low-fire rate position,
Middle = intermediate position,
High = open position.
The positions not used by the operating mode are
barred.
The “closed position” is always the calibrated zero posi-
tion of the device and cannot be readjusted. The other
positions can be defined on site.
IC 40 · Edition 07.18 13
Function
Basically, the following parameter limits must be noted.
Ascending sequence of positions:
0% = closed –>
low –>
middle –>
high ≤ 100%
The “high position” must not be selected less than
10 %.
If the positions have been changed in the software,
BCSoft checks the new values for compliance with the
limits and adapts the positions.
3.4 Running times
Up to 6 running times (t1 to t6), each between 0 and
max. 25.5 seconds, can be set dependent on the operating mode.
A minimum running time is required for each change in
position.

Times which are too short are automatically corrected
by the IC 40 to the minimum possible value. If the actuator is to operate as fast as possible, a time of 0 seconds can be preset.
In the case of position changes < 16.2%, the maximum
running time is reduced from 25.5 s percentage-wise.

The IC 40 corrects the time to the maximum possible
value.
After they have been entered, the valid parameters are
automatically read out and displayed in BCSoft.
We recommend switching to Manual mode when commissioning in order to establish the right positions
and running times for the application, see page 51
(Manual mode).
Outputs
In addition to feedback signals, it is also possible to
assign freely adjustable position ranges to the two outputs, RO 1 and RO 2, see page 50 (Outputs).
Statistics
The statistical data stored in the unit, such as faults
which have occurred, various counter readings and
measured values, are displayed and read out in BCSoft,
see page 52 (Statistics).
Emergency closing function
A pre-tensioned spiral spring moves the drive shaft with
valve disc to the closed position in the event of faults or
if the continuous supply voltage is interrupted, within
the closing time < 1 s, see page 43 (Emergency closing function).

Control via one digital input
If digital input DI 1 is activated (DI 2 with no signal), the
actuator moves to “high” position. The running times t

Likewise, the actuator closes within the successive running times t

Owing to the two successive running times, the opening characteristic of the butterfly valve can be changed.
For example, the characteristic of the air circuit can be
adapted to that of the gas circuit.
Running times up to 51 s (2 x 25.5 s) are possible in this
operating mode. If the signal at digital input DI 1 is deactivated before “high” position is reached, the actuator
moves directly to “low” position within the percentage

If only digital input DI 1 is active, the actuator opens. If

If neither of the digital inputs or both digital inputs are
active simultaneously, the actuator stops in its position.
This means that it can be stopped in any position.
The actuator operates in continuous mode and is con-
trolled via a 3-point step signal. The setting function is
limited by the “low” and “high” positions (“low” position
may also be 0° = “closed” position).
The opening speed is preset via the time t

Operating mode 6
3.5.6 3-stage operation with one or two digital inputs
Operating mode 6
Each of the 4 circuit combinations resulting from DI 1
and DI 2 determines precisely one actuator position:
DI 1 DI 2 Position
Off Off closed
On Off low
Off On middle
On On high
Each signal change results in a new position setpoint
for the actuator. If the signals overlap (see t2), the actuator moves towards “high”. If the signals do not overlap
(see t5), the actuator moves towards “closed”.

Various modes of operation can be implemented with
this operating mode.
Control via one digital input
DI 2 with no signal:
The actuator operates in low/closed intermittent mode
via digital input DI 1.
DI 1 with no signal:
The actuator operates in middle/low intermittent mode
via digital input DI 2.

Operating mode 6
DI 1 with continuous signal, for instance resulting from
inversion of the logic, see page 48 (Switching logic):
The actuator operates in high/low (high/closed) inter-
mittent mode via digital input DI 2 with two successive
running times up to 51 s (2 x 25.5 s).
DI 1 and DI 2 are connected in parallel:
The actuator operates with one signal in high/closed
intermittent mode with three successive running times
up to 76.5 s (3 x 25.5 s).
With three successive running times via interpolation
points, it is possible to change the opening characteristic of the butterfly valve. For example, the characteristic of the air circuit can be adapted to that of the gas
circuit.

Control via two digital inputs
If all possible combinations of the two inputs are used,
for instance by a PLC control system, it is possible to
implement high/middle/low/closed intermittent mode
(3 stages plus the “closed” position).
Possible parameter set for this operating mode:
P 68001, see page 45 (Parameter sets).
