Solution
Temperature detection circuit is
abnormal.
Temperature detection sensor is
abnormal;
Temperature detection
circuit is abnormal;
The actual temperature is too
low. So low
pre-alarm is released as normal
to prevent air compressor from
starting.
Solution
Stop and carry out maintenance.

Stop and carry out maintenance.
Check if pressure detection sensor
is abnormal;
The input P2 signal wire of
pressure detection is dropped.
Detect if PT100 wiring is normal;
Temperature detection sensor is
is
abnormal;
Temperature detection circuit is
abnormal.
