How to test a sensor in order to know if it
still work # 007

1. Sensor installation & positionning
•
The flat face of the sensor shall be about 6-7mm away from the steel
surface it should detect.
•
The « black plastic » end of the sensor, shall not be too close as well from
the « bracket » where you attach it. If the nuts is too close from the « black
plastic » cover, the sensor shall be «
turned on » all the time.
•
A wrongly positionned sensor, might get damage by moveable parts of the
machine. Make sure to install the correctly.
2. Validate sensor reactions to stimuli
•
If the sensor is already facing a steel surface, you should normally see the
LED light on the sensor turning on. If it light on.
•
Check on the computer screen diagnostic mode. The sensor status
shall
be green. If it’s green, your sensor is working
•
If the sensor LED light is ON, but the sensor status in the diagnostic
mode is RED, it mean your signal wire is cutted/damaged in between
the sensor and the computer. Inspect wire.
•
If the sensor is not facing a steel surface, use a steel object and put it in
reach of the sensor to stimulate the sensor and see if it react to stimuli and
then check the sensor status in the diagnostic mode as explain above.
3. Validate if sensor malfunction or electrical power issue
•
If your sensor do not react to stimuli, take a new sensor, and connect it in
place of a sensor that is currently lighted up, and make sure the new one
you intend to use is working as well.
•
Now use that sensor, and replace the « defective » sensor
•
If replacing the sensor by a new one solve your problem, then your sensor
was broken.
•
If by replacing the sensor, the new one do not « lighted up » or react to any
stimuli, then most probably you
don’t have 12V power on the wire
connected to that sensor. Go to Step #4
4. 12V electrical power supply issue
•
Use a voltmeter, and validate you are having 12V power at the end of the
connector linking the sensor and wires.
•
Inspect the wires up to the source to find out the source of the problem.
