Low Humidity Safety Protection Function; The Fault Detection Function - Philco PDA20DX User Manual

Low humidity safety protection function

2 the machine detects the humidity of the environment humidity is less than or equal to 30%, double
eight to indicate Lo, dehumidification icon
(i.e., compressor stop working), the motor is still to maintain the original setting operation. The
machine detects ambient humidity, humidity is greater than or equal to 32%, double eight indicator
light shows the actual humidity dehumidifying operation, machine recovery (protection time
compressor start relay for 3 minutes)
The machine detects ambient humidity is greater than or equal to 91%RH when the humidity double
eight to display Hi, keep the original state of the working machine.
(Note: only the running dehumidifying operation has this function)

The fault detection function

1. The machine is arranged in the drying operation, sensor detect body and circuit. abnormal condition.
The sensor when the machine detects a failure of the temperature of the evaporator (open circuit, short
circuit), the machine stops running, while the digital display shows C1 and flashing. Touch any key does not
work, relieving method: need machine power off and then power or after troubleshooting to power on.
2. The sensor when the machine to detect environmental temperature fault (open circuit, short circuit),
temperature and humidity sensor connected line loose, the machine stops running, while the digital
display shows C2 and flashing, touch any button does not need machine, power off and then power or
troubleshooting after power on.
3. The machine in operation, DC detects a DC motor to stop running after 15 seconds, the machine stops
running, while the digital display shows C7 and flashing. Be ruled out after the failure again electrify
switches on the mobile phone.
4. Refrigerant leakage detecting: if the refrigerant refrigeration system caused by the leakage of the
machine is not cooling, the temperature of the evaporator will rise and close to the ambient temperature.
The working of the compressor is running, every 8 minutes to detect a temperature value and the
evaporator temperature value; if two consecutive testing to the environment temperature and the
temperature of the evaporator and the difference is less than or equal to 3℃, said refrigerant cooling
system leaks, the machine stops running at the same time, digital display, display C8 and flashing. The
required power off and then power or after troubleshooting power on. (Note: when the compressor
stops working without the test)
flashes, the machine stops dehumidification operation
