Output relay warning

What does A881 mean?

A warning generated by an edge counter, typically indicating that a programmable limit for output relay operations has been reached. An auxiliary code in the event log will specify the exact source.

• Programmable warning set by parameter 33.35 Edge counter 1 warning selection or 33.45 Edge counter 2 warning selection.
• The source of the warning is defined by 33.33 Edge counter 1 source (aux code 2) or 33.43 Edge counter 2 source (aux code 3).
• Configured edge counter reaching its programmed threshold, indicating a limit on relay switching cycles has been met.

Click steps to track your progress.

1. 1

   Check the event log for the specific auxiliary code associated with the A881 warning.

2. 2

   Identify the source of the warning by cross-referencing the auxiliary code with parameters 33.33 or 33.43.

3. 3

   Investigate the conditions triggering the configured edge counter (e.g., frequent relay switching) and the specific output relay in question.

4. 4

   Inspect the associated output relay for signs of wear or degradation due to excessive switching cycles.

5. 5

   Adjust the warning selection parameters (33.35, 33.45) if the warning threshold is inappropriate for the application, or reduce relay switching frequency.
