Monitored Start with Falling Edge
In the case of a monitored start with falling edge, the start input must be activated and remain active
for a duration of 80 ms. The safety-related outputs are activated with a falling edge of the start input
if the safety-related inputs have been activated in the meantime.
1 Activation delay (100 ms): maximum time between deactivation of start input and activation of safety-
related output
2 Response time (20 ms): maximum time between deactivation of safety-related input and deactivation of
safety-related output
3 Waiting time after power-on (2500 ms): time that must pass between power-on and activation of the start
input
4 Minimum duration of start pulse (80 ms): time for which the start input must be activated before the falling
edge at the start input
The timing diagram exemplifies the timing using one safety-related input and one safety-related
output. The same logic applies in the case of multiple safety-related inputs and/or safety-related
outputs.
The signal required for activation of the Start input can be provided, for example, via a push-button
or a logic controller.
