Time This parameter monitors the time that elapses between pressing the “PRERESET” button and
the actual reset button.
The monitoring time can be parameterized between 6 and 120 s. The time starts on a falling
edge of the “P
RERESET” button and ends on acknowledgment with the reset button (maxi-
mum time between setting the “W
AIT” output and the “Q” output).
Blocking mandatory /
Blocking number
This parameter is used to specify the maximum blocking number at the “I
N” input (e.g., in-
terruptions of the protective field of a light grid). The operator checks that after the valid
“P
RERESET” signal the maximum number of signal changes (transition from logic “1” to “0”)
at the “I
N” input is not exceeded (at least once however). The “RESET” signal can only be ac-
tuated when the protective field of the light grid is clear again.
If this parameter is deactivated, no check is performed.
