2 Product description of safety module CAMC-G-S3
The rapid detection of a safety requirement can be activated using the "Quick detection request" para­
meter (P02.08/...). If both inputs, DIN40A and DIN40B, change level simultaneously, then the switching
status is forwarded to the logical signal LIN_D40, by-passing the "LPF" filter. This means that very rapid
detection of a safety function request is possible, even in the case of relatively long test pulses and
thus large time constant of the filter.
After the request of a safety function via DIN40 ... DIN43, the following times elapse until the logical
input LIN_D... and thus the safety function request is activated:

"Filter time constant" (P02.04/09/0E/13)
Reaction time for "Quick detection request" = 0
