#912 Abnormal Fire Detection

FLUX Support Team
  • Updated

 

Possible causes:

  1. The environment light or sunlight is reflected by the material and triggers the sensor.
  2. The system fails (Re-update the firmware, reset to factory, or reflash SD card.)
  3. The sensor or cable of the fire detection is dead.
  4. The mainboard/MB/motherboard is malfunctioning.

 

Step 1

Check if the sensor has a rubber cap installed or if the sensor is damaged, bent, or melted.

Good Example - Straight with Cap & No Damage 
Bad Example - Bent
Bad Example - Sensor Cap Missing
Bad Example - The Sensor Missing

 

Determine the test result and the next action to take.

  • The sensor looks good >> Step 2

 

Step 2

  • Remove all materials from the work area.
  • Turn off the environment light and close the curtains, or use a blanket or board to prevent any external light source from triggering the sensor. (Avoid any light entering the machine.)
  • Check the flame sensor value on the panel.
    • Value 0-100 = Sensor is not triggered.
    • Value 1000 or above = Sensor is triggered.

  

Determine the test result and the next action to take.

  • The value is 0-100 >> The machine has no problem
    • Possible cause:
      1. The material reflects the environmental light source or sunlight and triggers the sensor. 
  • The value is 1000 or above >> Step 3

 

Step 3

 

Determine the test result and the next action to take.

  • The value is 0-100 >> Problem Solved
    • Possible cause:
      1. The system failed
  • The value is 1000 or above >> Step 4

 

Step 4

Turn off the machine to unplug the gray ribbon cable and check the flame sensor value again.

  • Turn off the machine.
    Remove the side cover by unscrewing these T8 screws and unplug the two USB extensions.

    (Refer to the     diagram if your PCB board is not the same as the photo.)

 

  • Turn on the machine and check the flame value.


Determine the test result and the next action to take.

  • The value is 0-100 >> Contact Customer Support  
    • Possible cause:
      1. The flame sensor is faulty
      2. The 6-pin cable for the flame sensor is faulty (Less likely)
      3. The ribbon cable is faulty (Less likely)
      4. The plotter is faulty (Less likely)
  • The value is 1000 or above >> Contact Customer Support
    • Possible cause:
      1. The mainboard is faulty and needs to be replaced.
