Note: 1. External noise is probable as a cause of “---”, “e01”, “e02”, “e03”, “e04”, and “e05” errors.
2. Operation out of the derating curve area, ventilation error, and incorrect mounting direction are probable as a cause of “h\t” error.
3. If the “h\t” error state continues for more than three hours, the maintenance forecast monitor function becomes invalid. The Yrs output
(Maintenance forecast output terminal (Yrs)) will remain OFF (no continuity).
Replace the power supply if this condition occurs even if the output is correct, as internal parts may be deteriorated.
4. The “h\t” error detection function is only for the S8VS-@@@24A@@.
