System error channel 2

What does F3146 mean?

A system error has been detected in safety channel 2. Safety systems often employ redundant channels to ensure reliability (e.g., dual-channel architecture). This fault indicates a failure or discrepancy within the second, independent safety processing path. This redundancy failure means the system can no longer guarantee its safety integrity, leading to a fault state.

• Hardware fault in safety channel 2's processing unit
• Software error affecting channel 2's execution
• Interference or noise affecting channel 2's signals
• Discrepancy between channel 1 and channel 2 outputs/inputs
• Power supply issue specific to safety channel 2

Click steps to track your progress.

1. 1

   Verify external wiring and connections of all safety input devices associated with safety channel 2 for continuity and proper termination.

2. 2

   Inspect the real-time status of safety input signals for channel 2 via the drive's diagnostic interface or appropriate measuring equipment.

3. 3

   Check the drive's safety configuration parameters, comparing current settings for channel 2 functionality against the machine's safety documentation.

4. 4

   Measure the auxiliary power supply voltage to the IndraDrive MPx02 to confirm stability and adherence to specified limits.
