Validation Button
With the validation button S1, several commands as well as the validation can be executed:
•
Acknowledging an error and exiting the error status
•
Deleting a configuration in the Safety CPU
•
Validation of the configured safety system
Inputting commands with the validation button consists of 3 sequential components; the start
and End sequence, and the sequence for selecting a command (see the following diagram).

Start Sequence
The button must be pushed until LED B lights (approximately 3 seconds) If the button is
pushed too long (longer the approximately 10 seconds), an Error sequence is initiated (see
"Error Sequence"). The same applies when the button is released too soon (before LED B
lights), or it is pushed immediately after being released (time between 2 button presses
shorter than 200 ms).
