IC 40 · Edition 07.18

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 (t
1
to t
6
), each between 0 and
max. 25.5 seconds, can be set dependent on the oper-
ating mode.
A minimum running time is required for each change in
position.
Minimum actuator running time t
min
:
t
min
=
4.5 s x change in position%
100%
Times which are too short are automatically corrected
by the IC 40 to the minimum possible value. If the ac-
tuator is to operate as fast as possible, a time of 0 sec-
onds 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 com-
missioning 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 out-
puts, 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 clos-
ing function).
