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 12.5A
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 7.5A, the frequency of
the compressor increases at the prohibited speed.
●
During the starting process of the compressor, if the AC current is greater than 6.5A, 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 12.5A 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.
