◆ Check of the sensor’s optical axis
If there is no screw at the stopper section, this machine continues operation, and if there are screws, it stops after a certain period of time
has passed. This machine has the level of the screw/no screw sensor adjusted by the reference rail on shipment. In reality, however, a level
adjustment of the sensor may become necessary when using thin-head screws or due to occurrence of the variation on rail replacement.
Then, follow the directions (1) and (2) for the adjustment.
(1)
•
Loose the sensor attaching screw on the side lit up as much as it moves by picking up the sensor holder with fingers, and
turn on the power switch.
•
Place a screw on the fail within the sensor range.
•
Hold the rail end lightly with fingers as much as it doesn’t vibrate so that screws doesn’t pass through.
•
When the sensor holder is moved up and down, there is a position the sensor of the receiving light side defects a screw head
and stops the vibration. Tight the sensor attaching screw at this position.
•
Confirm whether it really works or not. See if a screw passes
through and the sensor detects if and stops.
(2)
•
Remove the machine body rear cover, and measure the
voltage level. Adjust the IC4050 7th-pin voltage level. The
ground, when measuring it, is the body’s metal part.
•
Adjustment is not necessary if the voltage level is within 0.25 to
1.5V when a rail is and if there is no screw at the stopper section.
•
When adjustment is necessary, loosen the sensor attaching
screw on the side. Adjust the voltage level by moving it up
and down. (It is easier to make an adjustment if connector of
the main motor is removed.)
•
After the adjustment, throw in the screws and run it practically
in order to check the operation.
Note
: When no loaded screws are: 0.25 V to 1.5 V When loaded
screws are: 3.5 V or more.
