6.2 Faults and countermeasures for air compressor device
Fault and countermeasures for air compressor device are listed as below:
P19.13
Status type
Possible cause
Solution
BIT0=1
Air filter is blocked Air filter is abnormal.
Stop and check the air filter
BIT1=1
Oil filter is blocked Oil filter is abnormal.
Stop and check the oil filter
BIT2=1 Separator is blocked Separator is abnormal.
Stop and check the separator
BIT3=1
Splitter is blocked Splitter is abnormal.
Stop and check the splitter
BIT8=1
Pressure pre-alarm
The actual pressure detected
by P1 is larger than the
pre-alarm pressure set by
P18.17.
Check if solenoid valve is
normal;
Check
if
pressure
control
parameters are set correctly.
BIT9=1
Temperature
pre-alarm
The
actual
temperature
detected by PT1 is larger than
the pre-alarm temperature set
by P18.19.
Check if control parameters of
the fan are set correctly;
Check if the fan operates
normally;
The fan power is too small for
effective cooling;
Check if there is lubricating oil.
BIT10=1
Pressure alarm
The actual pressure detected
by P1 is larger than the alarm
pressure set by P18.18.
Check if solenoid valve is
normal;
Check
if
pressure
control
parameters are set correctly.
BIT11=1
Temperature alarm
The
actual
temperature
detected by PT1 is larger than
the alarm temperature set by
P18.20.
Check if control parameters of
the fan are set correctly;
Check if the fan operates
normally;
The fan power is too small for
effective cooling;
Check if there is lubricating oil.
BIT12=1 Pressure signal fault
The actual pressure detected
by P1 is less than 1V.
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.
BIT13=1
Temperature signal
fault
PT100 sensor is disconnected.
Check if the wiring of PT100 is
normal;
Temperature detection sensor is
abnormal;
