7.1.5.3 The control of preventing the over current of the compressor:
During the starting process of the compressor, if the current of the compressor is greater than 10A
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 power is off.
During the starting process of the compressor, if the AC current is greater than 9A, 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 8A, 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 7A, the frequency
of the compressor increases at the prohibited speed.
During the starting process of the compressor, if the AC current is greater than 6A, the frequency
of the compressor increases at the speed of no faster than 0.1HZ/second.
7.1.5.4 The protection function of AC current:
During the starting process of the compressor, if the AC current is greater than 10A 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 8A, 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 7.5A, the frequency
The compressor stops
N Decreasing the frequency rapidly
P Decreasing the frequency slowly
Q Prohibiting increasing the frequency
R Increasing slowly
