Click steps to track your progress.
Identify the physical digital input terminal associated with 'Activate fault 1' as configured in Parameter 0x2.
Measure the voltage level at the identified digital input terminal (e.g., 24VDC or 0VDC) to verify its state when the fault occurs.
Verify the status and operation of the external sensor or device connected to this input, ensuring its output is as expected.
Review Parameter 0x2 settings to confirm the correct input source and logic (e.g., normally open, normally closed) are selected.
Temporarily disconnect the external signal from the digital input terminal and observe if the fault clears, indicating an external signal issue.
