Possible cause
detected by PT1 is larger than
the alarm temperature set by
P18.20
The actual pressure detected
by P1 is less 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
exceed the set time of P19.00
The running time of part 2
exceed the set time of P19.01
The running time of part 3
exceed the set time of P19.02
The running time of part 4
exceed the set time of P19.03
The running time of part 5
exceed the set time of P19.04
The actual pressure detected
by P2 is less than 1V
Corrective measures
are set correctly;
Check if the fan operates normally;
The fan power is too small for effective
cooling;
Check if there is lubricating oil
Check if pressure detection sensor is
abnormal;
The input P1 signal wire of pressure
detection is dropped;
The pressure signal interface does not
select current signal
Check if the wiring of PT100 is normal;
Temperature detection sensor is
abnormal;
Temperature detection circuit is
abnormal
Temperature detection sensor is
abnormal;
Temperature detection input circuit is
abnormal
The actual temperature is too low. So
low temperature pre-alarm is released
as normal to prevent air compressor
from starting.
