10.6. Sensors
10.6.1 Doubles Detection
a) Cables
o
Visually inspect cables for damage.
Note: Only one of the cables should emit light, the other cable is only for receiving the light.
o
To test a cable have the machine powered on and observe the display on the optic amplifier . Wiggle
the optical cables individually and watch for any major variation of the signal strength readout. If the
readout varies when either cable is moved, then that cable must be replaced.
Swing open the clear plastic guard on the optic amplifier.
ƒ
Slide the end of the right side of the optic amplifier away from the machine and remove the
optical cables from amplifier .
o
If neither cable emits light try switching their positions in the optic amplifier. If this works likely one of
the cables if bad. Isolate the bad cable and replace.
