|Alarm meaning||Compressor 1 (INV) overcurrent alarm.|
This alarm occurs when current trouble or current detection trouble occur (when trouble judgment current is detected in the primary or secondary current, or when an instantaneous secondary current of 18A* or higher is detected).
1. When more than the over-current values shown in the table were detected in the primary and secondary current.
|Probable cause||There is a strong possibility of a compressor failure. An alarm occurs for current detection trouble when it is judged that no current is flowing after start (DCCT is damaged). In this case, the cause is a DCCT failure.|
|Check||Check the power wiring and connector wiring.|
|Correction||It is possible to resolve this trouble by limiting the maximum frequency.|
