Test mode
The limit value violation of the safety sub-functions SS1, SS2, and SOS can be tested when test mode is active.
The test mode suppresses the basic device control (FCB selection).
The test mode is activated by a rising edge (0 → 1) at a safe digital input or via the safe process output data (F-PO).
The status of the test mode is signaled by the safe process data (process data bit: Test mode active), in the "Assist CS.." parameterization tool and via the LED display.
The test mode is automatically exited in the following cases:
- During parameterization of the safety option.
- By opening the internal safe digital output F-DO_STO (e.g. fault response, limit violation, activation of STO safety sub-function).
- 5 minutes after activation.
Once it automatically finishes, the test mode can be activated again with a rising edge.
