Signal supervision

What does A8B0 mean?

A warning generated by a signal supervision function. This indicates that a monitored signal has deviated from its expected range or state, triggering a programmable alert.

• Programmable warning set by parameter 32.06 Superv1 action, 32.16 Superv2 action, or 32.26 Superv3 action.
• The source of the warning is defined by parameters 32.07, 32.17, or 32.28.
• The supervised signal has gone out of its configured acceptable range (e.g., too high, too low, or incorrect state).

Click steps to track your progress.

1. 1

   Identify which supervision function (1, 2, or 3) triggered the warning by checking active warning parameters in group 04 Warnings and faults.

2. 2

   Review the corresponding action parameter (32.06, 32.16, or 32.26) to confirm the warning is enabled.

3. 3

   Check the source parameter (32.07, 32.17, or 32.28) for the specific signal being supervised.

4. 4

   Investigate the actual value and integrity of the supervised signal to determine why it went out of its expected range or state.

5. 5

   Adjust the supervision limits, thresholds, or source if they are incorrectly configured for the application.
