Module Fault (Group)

¿Qué significa GROUP Value 3 ?

The 'ModuleFault' input for the EL/EJ69x0 group is active (set to 1). This indicates a general fault detected by the safety module itself, possibly a hardware issue, internal diagnostic failure, or a critical input signal indicating a module problem. The group will enter an ERROR state, preventing safe operation.

• Internal hardware fault or persistent diagnostic error within the EL/EJ69x0 safety controller itself.
• External 24VDC supply voltage to the EL/EJ69x0 module being outside specification (e.g., below 20.4V or above 28.8V at terminal U_S).
• Firmware corruption or unexpected behavior within the EL/EJ69x0 safety controller.
• Over-current or short-circuit condition on the safety outputs (e.g., OSSD output X1-1 shorted) detected by the module's internal diagnostics.

1. 1

   1. Verify the 24VDC power supply voltage at the EL/EJ69x0 module's power terminals (e.g., U_S) using a multimeter.

2. 2

   2. Check the diagnostic LEDs on the EL/EJ69x0 module for specific fault patterns or colors (e.g., red ERR LED).

3. 3

   3. Review the TwinCAT System Manager safety log for detailed module-specific diagnostic messages (e.g., internal voltage fault).

4. 4

   4. Perform a controlled power cycle of the entire EL/EJ69x0 module and its associated EtherCAT segment.

5. 5

   5. Ensure no over-current or short-circuit conditions exist on the module's safety output channels (e.g., measuring resistance to ground).
