|Alarm meaning||Compressor 1 (INV) overcurrent alarm|
|Alarm conditions||This alarm occurs when current trouble or current detection trouble occur at an inverter frequency of less than 80 Hz after start (when trouble judgment current is detected in the primary or secondary current, or when an instantaneous secondary current of 48 A or higher is detected.|
|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.|
