Possible cause
Actual temperature detected
by PT1 is higher than the
alarm temperature set by
P18.20.
The
detected by P1 to be less
fault
than 1V.
PT100 sensor is
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.

Solution
• Check whether fan control
parameters are correct.
• Whether fan operates
normally.
• Fan power is too small to
dissipate heat effectively.
• Check whether there is
lubricating oil.
• Pressure detection sensor is
abnormal.
• Pressure detection input P1
signal wire is disconnected.
• Pressure signal interface does
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, if not
calibrated.
• Actual temperature is too low,
and low temperature pre-alarm
is reported accordingly, and
therefore the air compressor
cannot start.
