Goodrive300-01A-RT series integrated machine Fault handling and product maintenance
-94-
Actual temperature detected
by PT1 is higher than the
alarm temperature set by
P18.20.
• 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.
The actual voltage is
detected by P1 to be less
than 1V.
• Pressure detection sensor is
abnormal.
• Pressure detection input P1
signal wire is disconnected.
• Pressure signal interface does
not select current signal.
PT100 sensor is
disconnected.
• Check whether the wiring of
PT100 is normal.
• Check whether temperature
detection sensor is abnormal.
• Temperature detection input
circuit is abnormal.
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, if not
calibrated.
• Actual temperature is too low,
and low temperature pre-alarm
is reported accordingly, and
therefore the air compressor
cannot start.
The running time of part 1
exceeds the time set by
P19.00.
Carry out maintenance after stop
The running time of part 2
exceeds the time set by
P19.01.
Carry out maintenance after stop
