P19.13
Status type
Possible cause
Solution
Temperature detection circuit is
abnormal.
BIT14=1
Low temperature
protection pre-alarm
The actual temperature
detected by PT1 is less than
the low temperature protection
threshold set by P18.21.
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.
P19.14
Status type
Possible cause
Solution
BIT0=1
Part 1 needs
maintenance
The part 1 working hours
exceeds the set time in
P19.00.
Stop and carry out maintenance.
BIT1=1
Part 2 needs
maintenance
The part 2 working hours
exceeds the set time in
P19.01.
Stop and carry out maintenance.
BIT2=1
Part 3 needs
maintenance
The part 3 working hours
exceeds the set time in
P19.02.
Stop and carry out maintenance.
BIT3=1
Part 4 needs
maintenance
The part 4 working hours
exceeds the set time in
P19.03.
Stop and carry out maintenance.
BIT4=1
Part 5 needs
maintenance
The part 5 working hours
exceeds the set time in
P19.04.
Stop and carry out maintenance.
BIT5=1
Auxiliary pressure
signal fault
The actual pressure
detected by P2 is less than
1V.
Check if pressure detection sensor
is abnormal;
The input P2 signal wire of
pressure detection is dropped.
BIT6=1
Auxiliary
temperature signal
fault
PT100 sensor is
disconnected.
Detect if PT100 wiring is normal;
Temperature detection sensor is
abnormal;
Temperature detection circuit is
abnormal.
