Status type
Possible cause
Solution
BIT7=1
Auxiliary pressure
pre-alarm
The actual pressure
detected by P2 is larger than
the pre-alarm pressure set
by P18.17.
Check if pressure detection sensor
is abnormal;
The set value of pressure is too
large;
Adjust pressure PID regulator
BIT8=1
Auxiliary
temperature
pre-alarm
The actual temperature
detected by PT2 is larger
than the pre-alarm
temperature set by P18.19.
Temperature detection sensor is
abnormal;
Temperature detection input circuit
is abnormal;
The starting temperature of the fan
is set to high;
The set temperature of the fan is
too high;
The fan power is too low for
effective cooling.
BIT9=1
Auxiliary pressure
alarm
The actual pressure
detected by P2 is larger than
the alarm pressure set by
P18.18.
Check if pressure detection sensor
is abnormal;
The set value of pressure is too
large;
Adjust pressure PID regulator
BIT10=1
Auxiliary
temperature alarm
The actual temperature
detected by PT2 is larger
than the alarm temperature
set by P18.20.
Temperature detection sensor is
abnormal;
Temperature detection input circuit
is abnormal;
The starting temperature of the fan
is set to high;
The set temperature of the fan is
too high;
The fan power is too low for
effective cooling.
BIT11=1
Maintenance
time-out alarm
Any part whose working time
exceeds the set time will
enter time-out maintenance
stage. Then if its working
time exceeds the time set by
P18.45, system will release
alarm.
Conduct maintenance on time-out
parts after stop.
