IC 40 function
4..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 operating mode.
A minimum running time is required for each change in posi-tion.
Minimum actuator running time t
min
:
4.5 s x change in position %
t
min
=
100%
Times which are too short are automatically corrected by the IC
40 to the minimum possible value. If the actuator is to oper-ate as
fast as possible, a time of 0 seconds can be pre-set.
In the case of undershoot 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 auto-
matically read out and displayed in BCSoft
®
.
We recommend switching to Manual mode when commis-sioning
in order to establish the right positions and running times for the
application, see page 60 (Manual mode).
Outputs
In addition to feedback signals, it is also possible to apply freely
adjustable position ranges to the two outputs, RO 1 and RO 2,
see page 59 (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 61 (Statistics).
Safety closing function
A pre-tensioned spiral spring moves the drive shaft with valve disc
against the mechanical stop of the butterfly valve to closed
position in the event of faults or if the continuous supply voltage is
interrupted, within the closing time < 1 s, see page 52 (Safety
closing function).
