Validation Button
With the validation button S1, several commands as well as the validation can be execut-
ed:
•
Acknowledging an error and exiting the error status
•
Deleting a configuration from the Safety CPU
•
Validating the safety system configuration
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).

Explanation of the individual sequences
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).
