Functions
3.1 When the PTC heater detector SENSOR sensing the temperature gets to 80
℃
, the PTC heater will
Force OFF. Ventilation fan and the circulation fan will run by the original setting;
3.2. When the PTC heater detector SENSOR induction temperature gets to 80
℃
~ 90
℃
, If the
temperature detector SENSOR detected temperature dropped below 50
℃
, PTC will recover and turn on
automatically , the fan gear set will back to the previous state; (Between 80
℃
~ 90
℃
, the machine does
not display the fault code “ ”, buzzer will not respond).
3.3. When the temperature rising to 90
℃
, the PTC heater will Force OFF, ventilation fan will shift to high
speed, display board shows high temperature protection fault code “HE”, buzzer will ring once every
second.
3.4. During the high temperature protection fault, if temperature cannot dropped to below 65
℃
, the
ventilation Fan continues to run in high speed gear, and any changing in function mode is not allowed.
User can only turn off the machine manually. After turning off manually, the fault code will be erased. If
the temperature dropped below 65
℃
, PTC will recover and be turned on automatically, the fan gear set
will back to the previous state;
Failure of Temperature Sensor
1. The Environment Temperature Sensor continuously test for 5 seconds for fault condition, the
display board shows Fault Code “ ”
2. The PTC Temperature Sensor continuously test for 5 seconds for fault condition, the display board
shows Fault Code “ ”
3. To test Both Environment Temperature Sensor and PTC Temperature Sensor faults, all overload
are closed, the display board shows Fault Code (If there are a few faults happened at the same
time, Fault Code will be displayed alternatively for 3 seconds) and the machine is Force Stop. Any
changing in function mode is not allowed, until after the Temperature Sensor Fault is eliminated
before the machine can function again.
Fault Code
1. High Temperature Protection: display board shows Fault Code, “ ”
2. Environmental Thermal Package Failure: display board shows Fault Code “ ”
3. PTC Thermal Package Failure: display board shows fault code “ ”
