Cause : External Fault (Terminal S4) comes when the wiring is incorrect or MFDI terminal S4 caused an external fault through an external device. External Fault [H1-01 = 2C to 2F] is set to MFDI terminal S4, but the terminal is not in use.
1. Find the device that caused the external fault and remove the cause.
2. Clear the external fault input in the MFDI.
