Automatic Start
With automatic start, the start input is permanently active. This can be achieved by bridging the
start input or providing an external power supply. When the safety-related input is activated, the
safety-related outputs are activated within a maximum of 100 ms (activation delay).
The following timing diagram illustrates the automatic start:
1 Activation delay (100 ms): maximum time between activation of safety-related 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 Recovery time (200 ms): time that must pass before the safety-related input can be activated again
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.
