Error when checking acknowledgment signal

What does F3131 mean?

An error occurred during the verification of a safety-related acknowledgment signal. Acknowledgment signals are used to confirm that a safety condition has been met or a safety command has been processed, often after a fault. Failure to correctly process this signal indicates a problem with the safety feedback loop, preventing system reset or safe operation.

• Faulty wiring for the acknowledgment button/input
• Defective acknowledgment button or sensor
• Acknowledgment signal not received within the expected timeframe
• Incorrect state transition logic for acknowledgment
• Internal safety module processing fault for acknowledgment

Click steps to track your progress.

1. 1

   Inspect the wiring and terminal connections of the safety acknowledgment signal path for loose connections, damage, or incorrect routing.

2. 2

   Verify the status of the safety acknowledgment input signal via the IndraDrive's diagnostic interface or HMI, confirming it transitions as expected.

3. 3

   Measure the voltage level of the safety acknowledgment signal at the IndraDrive input terminals against the nominal voltage specified in the wiring diagram.

4. 4

   Check IndraDrive safety parameters (e.g., S300/S400 parameters) governing the acknowledgment signal configuration against the machine's safety manual.
