11.3 Response time and release time in a safe series connection
The reaction times are subject to the following parameters:
•
R
esponse time or enable time
•
Number of devices in series connection
Response time (removal of actuator from response range)
R
esponse time for series connection: 40 ms × number of safety switches in series con‐
nection
Enable time (actuator approaching response range)
Release time for series connection: 100 ms × number of safety switches in series con‐
nection
Risk time (error detection time for external faults)
Risk time for series connection: 100 ms +40 ms * (number of safety switches in series
connection -1)
