5 - 8. Sensor Voltage Level Adjustment
Screws can generally be used without further adjustment after the initial adjust-
ment. However, if you are using screws outside the specifications in this manual,
the machine may not work properly. In this case check and readjust the following:
Adjust the sensor levels for when screws are on the rail and for when no screws
are on the rail.
Remove the rear cover of the machine to check the IC on the printed circuit board.
(See Picture 17)
Measure the voltage level using Pins 3, 5, and 7 on the IC4050. Ground the metal
part of the body. (Use testing clips for the voltage measurement. Recommended
item: Testing clip <FP-7> manufactured by Sunhayato Corp.)
*** Screw Sensor Adjustment (Pin 3) ***
The screw sensor detects whether or not there are any screws re-
maining on the rail.
Loosen the light receiving sensor bracket fixing screws (2 pcs.) and
adjust the sensor level by rotating the bracket. (See Picture 18)
0.25 – 1.5V: There are no screws remaining on the rail.
3.5V or more: There are screws on the rail.
If the voltage is 2.5V or over, the sensor judges that there are
screws on the rail.
