6. Unnormal Communications
1) Follow the user manual and confirm whether is the problem of left sensor or right sensor.
2 ） When confirmed which door frame have communication problems, pull out its probe and reinsert for
several times,then test again. If problem the same, then replace the corresponding signal collection card,
main board and wire step by step until confirm the problems.
7. Whole Machine Non-inductivity
1) Check whether the communication is ok, follow above 6 steps.
2) If communication is ok, replace the mainboard or signal board step by step.
8. LCD Screen Problems, LED Bar Graph Not Lighting, Buttons Not Working
1) Replace the parts from other Walk Through metal detector to find the failure parts
【 INTERFERENCE 】
The interference during the walkthrough metal detector working,are mainly
as follow:
Electronic Jamming
Working frequency for the Walk Through metal detector is 4KHz-8KHz.
around the work environment should exclude the electronic products that
have the almost similar working frequency such as generator, TV etc.
Moving metal objects Interference
The Walk Through metal detector will be interfered by the moving metal
objects, around the work environment should not have turnstile and from
vehicle etc. big moving metal objects.
Interference Between Products And Products
During using 2 pieces or more Walk Through metal,should avoid using the
same frequency(the work frequency can be seen on the packing box),the
minimum distance between two doors should be above 0.7m to avoid the
mutual interference for the Walk Through metal detectors.
