PROTECTION
FAILURE CAUSE
AND CORRECTIVE ACTION
1. Whether there is power connected to the PCB
and driven board. Check the PCB indicator light
is on or off. If Light is off, reconnect the power
supply wire.
2. if light is on, check the wire connection
between the main PCB and driven PCB, if the
wire loosen or broken, reconnect the wire or
change a new wire.
3. Replace a new main PCB and driven board in
turn.
Same to P6
1. Strong wind or typhoon below toward to
the fan, to make the fan running in the
opposite direction. Change the unit
direction or make shelter to avoid typhoon
below to the fan.
2. fan motor is broken, change a new fan motor.
1. Whether the power supply input is in the
available range.
2. Power off and power on for several times
rapidly in short time. Remain the unit power off
for more than 3 minutes than power on.
3. the circuit defect part of Main control board is
defective. Replace a new Main PCB.
1. Pressure sensor connector is loosen, reconnect
it.
2. Pressure sensor failure. change a new sensor.
1. The EEprom parameter is error, rewrite the
EEprom data.
2. EEprom chip part is broken, change a new
EEprom chip part.
3. Main PCB is broken, change a new PCB.
