protection pre-alarm
P19.14 State type
Possible cause
Actual voltage detected by
P1 is larger than the alarm
voltage set by P18.18.
Actual temperature
detected by PT1 is higher
than the alarm temperature
set by P18.20.
The actual voltage is
detected by P1 to be 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

Fault information and troubleshooting
Solution
•
Fan power is too small to
dissipate heat effectively.
•
Check whether there is
lubricating oil.
•
Check whether solenoid valve
is normal.
•
Check whether pressure
control parameters are set
correctly.
•
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.
•
Actual temperature is too low,
and low -temperature
pre-alarm is reported
accordingly, and therefore the
air compressor cannot start.
