The Safe Disable inputs SD1 and SD2 have been activated via the OPT-AF option board.
Click steps to track your progress.
Verify the state of the Safe Disable inputs (SD1, SD2) on the OPT-AF board.
Inspect the wiring to the SD1 and SD2 terminals on the OPT-AF board.
Check the status of any connected external safety devices (e.g., emergency stop buttons, safety gates).
Temporarily bypass the OPT-AF board's safe disable inputs (if safe to do so) to isolate the fault.
Confirm the logic connected to the SD inputs is correctly configured for the safety application.
