Function
Operating mode 21 with prolonged running time
The “high” position can be selected correspondingly
lower in order to obtain longer running times (> 25.5 s).
The “high” position does not limit the adjustment angle
for the “open” position but defines only the speeds here.
Consequently, the “high” position may also be lower
than the “analogue” position. The magnitude of the cur-
rent signal is crucial as regards the “analogue” position.
Example for double running time T:
The “high” position is set to 50%.

Possible parameter set for this operating mode:
P68026, see page 45 (Parameter sets).
Note:
The running time can be prolonged up to max. 150 s for
the full adjustment range 0 – 90°. Running times out-
side of this permitted range are adapted automatically
by BCSoft.
