Error when checking interrupting circuits

What does F3133 mean?

An error was detected during the checking of safety-related interrupting circuits. These circuits are designed to safely remove power or stop motion in an emergency, often involving multiple redundant paths. This fault indicates a discrepancy or malfunction within these critical safety paths, potentially compromising the ability to safely shut down.

• Faulty wiring in the safety interrupting circuit (e.g., E-Stop loop)
• Defective safety relays or contactors in the interrupting circuit
• Bridging or tampering of safety circuit elements
• Inconsistent signals from redundant interrupting paths
• Internal safety module monitoring failure for interrupting circuits

Click steps to track your progress.

1. 1

   Verify the operational status of all external safety devices (e.g., E-stops, safety gates, light curtains, safety relays) connected to the IndraDrive's safety inputs.

2. 2

   Inspect the wiring for the safety-related interrupting circuits between external safety devices and the IndraDrive's safety terminals (e.g., X12, X13, X14) for loose connections, damage, or improper shielding.

3. 3

   Measure the voltage levels and continuity at the IndraDrive's safety input terminals according to the machine's safety circuit diagram to confirm correct signal presence and integrity.

4. 4

   Check the drive's safety function parameters (e.g., STO, SS1 configuration, safety input assignments) in the IndraDrive MPx02 to ensure they match the machine's safety concept and are correctly configured.
