5.2.5.3 The control of preventing the overcurrent of the compressor
During the starting process of the compressor, if the curren of the compressor is greater than
17A for 3 seconds, stop the compressor and alarm, after 3 minutes, start it again, if such state
appears 3 times in 20 minutes, stop the compressor and alarm, and confirm the malfunction.
Then continue to run it only after the the power is off.
During the starting process of the compressor, if the AC current is greater than 12A, the
frequency of the compressor decreases at the speed of 1HZ/second.
During the starting process of the compressor, if the AC current is greater than 10A, the
frequency of the compressor decreases at the speed of 0.1HZ/second.
During the starting process of the compressor, if the AC current is greater than 9A, the
frequency of the compressor increases at the prohibited speed.
During the starting process of the compressor, if the AC current is greater than 8A, the
frequency of the compressor increases at the speed of no faster than 0.1HZ/second.
5.2.5.4 The protection function of AC current:
During the starting process of the compressor, if the AC current is greater than 15A, the
frequency of the compressor decreases at the speed of 1HZ/second.
During the starting process of the compressor, if the AC current is greater than 13A, the
frequency of the compressor decreases at the speed of 0.1HZ/second.
During the starting process of the compressor, if the AC current is greater than 11A, the
frequency of the compressor increases at the prohibited speed.
During the starting process of the compressor, if the AC current is greater than 10A, the
frequency of the compressor increases at the speed of no faster than 0.1HZ/second.
Remarks: when the outdoor temperature is high, there’s compensation for AC current protection.
When the outdoor environment temperature is higher than 40 , AC current protection value
decreases by 10AD
When the outdoor environment temperature is higher than 46 ,AC current protection value
decreases by 15AD
