N0 status test to inactive

What does 13582 E013 mean?

The CCU shut-off signal '-N0' fails to switch to a high level, and its measured status is at a 'low' level. This indicates a potential software error or a hardware defect.

• CCU shut-off signal: -N0 does not switch to high level.
• The measured status of the "-N0" signal is "low" level.
• Software error.
• Hardware defective.

Click steps to track your progress.

1. 1

   Power cycle the NC control to attempt a reset of the safety circuit and signal states.

2. 2

   Check the wiring and connections related to the -N0 signal path for any damage, loose terminals, or improper shielding.

3. 3

   Inspect the controller board (CCU) for any visible damage, burnt components, or signs of hardware malfunction.

4. 4

   Verify the safety software configuration and parameters related to the -N0 signal's inactive state and its expected behavior.

5. 5

   If available, use a multimeter or oscilloscope to monitor the -N0 signal level and confirm it remains low when expected to transition to high.
