Error when checking acknowledgment signal

Was bedeutet F3131 ?

This non-fatal safety error occurs on the IndraDrive MPx02 when an expected acknowledgment signal for a safety function is either missing, incorrect, or not received within the specified timeframe. This prevents the safety function from proceeding or resetting, as the system cannot confirm its proper execution or reset state.

• Acknowledgment push button or external safety device malfunction.
• Wiring issue in the acknowledgment circuit (e.g., open circuit, short circuit).
• Incorrect parameterization of the acknowledgment monitoring time or logic.
• Communication fault preventing the acknowledgment signal from reaching the IndraDrive MPx02.
• Operator failed to provide the acknowledgment signal after a safety event.
