Manual Start
A manual start requires the start input to be activated. The safety-related outputs are activated after
both the start input and the safety-related inputs have been activated.
The following timing diagram illustrates the manual start:
1
Activation delay (100 ms): maximum time between activation 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
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.
The signal required for activation of the Start input can be provided, for example, via a push-button,
or a logic controller.
