6.3.3 Switching delay
The adjustable switching delay makes it possible to prevent the overspeed switch
switching if the limit speed is exceeded only briefly. That can be appropriate during load
shedding, for example. If the speed P4 is exceeded the switches S1, S2 and S3 close,
and open only after the delay time set in the "Delay" field has elapsed. It is possible to
set the time between 0 and 300 ms. The cut-off function is not triggered if the speed
again falls below the P4 figure within the set delay time.
PLEASE NOTE!
The delay time applies only to the cut-off function when the speed P4 is exceeded.
All other switching operations are triggered immediately.

6.4 Input accuracy of switching points
SGS C-Modul:
Switching speed n
Input accuracy
X: Integer places
Y: Decimal places
n < 100 rpm XX.YY (e.g.: 15.87)
100 >= n < 1000 rpm XXX.Y (e.g.: 280.3)
n >= 1000 rpm XXXX (e.g.: 2050)
SRC C-Modul:
The input accuracy of the position switching points depends on the calibration factor.
The input of position switching points is limited to 9 decimal places. The number of
places after the decimal point is limited to 3 decimal places.
