Alarm message of LCD panel--Machine protected（Old type sensor)

Question:

LCD panel shows the following information:


Reasons:

1. The doors with sensor are not closed

Our machine has protection sensors for door (front cover and laser tube cover), like below.



Solution:

Please close all the doors before starting work.

2. The induction magnet is not in good position


If any of the sensor magnets is in bad position


Solution:

  • Take out these three magnets and directly place them on their sensors.



To better induct the magnet, please approach it on either side of the sensor, instead of the center.


  • Put position the magnets on sensors like above pic shown, check if the red light of "If protection on " disappears.



LCD panel→ Z/U button→ Diagnoses+ → “ If Protection on “

If it shows Red color: At least one of the three protection sensors is not working well (if all doors are closed).

If it shows Grey color: All protection sensors are working normally.

  • If the red color disappears, it proves one of the magnets was in bad position. 
  • Then please install the magnets back to the doors one by one to test which one causes the issue, then fine tuning the position for it. 


3. The wires of DrProc and GND on CN2 is loose from controller board




If the wires are tight, maybe the door sensor is bad. Please contact us：tech@thunderlaser.com.
