sensor, (open-circuit) or above 1000H (short-circuit)
for 60 seconds. The fault is fixable.
The detected sensor value is below 20H
(open-circuit) or above 1000H (short-circuit)
for 60 seconds. The fault is fixable.
The detected sensor value is below 20H
temperature (open-circuit) or above 1000H (short-circuit)
for 60 seconds. The fault is fixable.
After 3 minutes of compressor operation, the

(open-circuit) or above 1000H (short-circuit)
for 60 seconds. Fixable when below 80°C.
The detected sensor value is below 20H
(open-circuit) or above 1000H (short-circuit)
for 60 seconds. 。
An alarm is given five seconds after the
current limit is exceeded. Where there are 3
alarms within 30 minutes, the fault code is
displayed. The fault is not fixable.
transformer When the compressor is shut off, the detected
current of current sensor is above 15A, and
when the compressor is started, the operating
frequency is above 60Hz and the detected
current is below 5A. The fault is fixable.

fault occurs three times within 30 minutes, an
alarm is given and the fault is not fixable.
