N0 status test to active

What does 13581 E012 mean?

The measured status of the '-N0' signal is at a 'high' level, and the '-N0' signal fails to change to the 'active' ('low' level) status. This indicates a potential software error or a hardware defect.

• The measured status of the "-N0" signal is "high" level.
• The "-N0" signal does not change to the "active" ("low" level) status.
• Software error.
• Hardware defective.

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 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 active state and its expected behavior.

5. 5

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