Test mode
The limit value violation of the safety subfunctions 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 subfunction).
- 5 minutes after activation.
Once it automatically finishes, the test mode can be activated again with a rising edge.
