Channel test pulse cross-talk error

What does 13 mean?

Cross-talk was detected during the test pulse operation on a safety I/O channel, indicating unwanted signal interference between channels. This can be caused by improper shielding, close proximity of signal wires, or a faulty sensor/module. This is a severity 3 error.

• Unwanted signal coupling between adjacent channels during test pulse.
• Insufficient isolation between input channels.
• Electromagnetic interference affecting signal integrity.
• Internal hardware issue causing signal leakage.

Click steps to track your progress.

1. 1

   Check the wiring connected to the safety I/O module channel for proper separation and shielding.

2. 2

   Inspect the sensor connected to the channel for potential internal short circuits or malfunctions.

3. 3

   If the error persists after verifying wiring and sensor, replace the I/O module.
