Possible cause

PT100 sensor is
fault disconnected.

The actual temperature
detected by PT1 is less
than the low
temperature protection
threshold set by
P18.21.
Possible cause

The running time of part
1 exceeds the time set
by P19.00.

The running time of part
2 exceeds the time set
by P19.01.

The running time of part
3 exceeds the time set
by P19.02.

The running time of part
4 exceeds the time set
by P19.03.

The running time of part
5 exceeds the time set
by P19.04.

The actual voltage
detected by P2 is less
than 1V.

PT100 sensor is
disconnected.
Fault information and troubleshooting
not select current signal.

Check whether the wiring of
PT100 is normal.

Check whether temperature
detection sensor is abnormal.

Temperature detection input
circuit is abnormal.

Temperature detection sensor
is abnormal.

Temperature detection input
circuit is abnormal.

Actual temperature is too low,
and low temperature
pre-alarm is reported
accordingly, and therefore the
air compressor cannot start.
