BIT5=1
Auxiliary pressure
signal fault
The actual voltage detected
by P2 is less than 1V.
• Pressure detection sensor is
abnormal.
• Pressure detection input P2
signal wire is disconnected.
BIT6=1
Auxiliary temperature
signal fault
PT100 sensor is
disconnected.
• Check whether the wiring of
PT100 is normal.
• Temperature detection sensor
is abnormal.
• Temperature detection input
circuit is abnormal.
BIT7=1
Auxiliary pressure
pre-alarm
The actual voltage detected
by P2 is larger than the
pre-alarm pressure set by
P18.17
• Pressure detection sensor is
abnormal.
• The pressure is set to a too
large value.
• 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, if not
calibrated.
• The starting temperature of
the fan is set to a too high
value.
• The temperature of the fan is
set to a too high value.
• Fan power is too small to
