Channel Test Pulse Cross-Talk Error

What does 13 mean?

This error suggests that a test pulse intended for one channel is being incorrectly detected on another, or vice-versa, indicating signal interference between channels. This can be caused by faulty wiring or internal issues within the I/O module, leading to unreliable input detection.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the error persists after checking wiring and sensors, consider replacing the I/O module as it may have an internal fault.

2. 4

   If the problem still persists, contact ABB technical support for advanced diagnostics.
