Adjustment of reflector type sensors
The sensor shall be capable of detecting black glass epoxy PWBs with no gloss (no resist) and glass epoxy PWBs with green
resist on bottom surfaces and with no resist on R surfaces.
1. Turn the sensitivity adjustment knob of the sensor to the MIN position.
2. Place a black glass epoxy PWB with no gloss (no resist) on the transport rails above the sensor.
3. Slowly turn the sensitivity adjustment knob of the sensor clockwise from the MIN position and stop turning it when the
indicator lamp lights up.

This adjustment ensures that the sensor detects PWBs of various colors and does not sense any object including the safety
cover other than PWBs.

[1] For the adjustment, use as the workpiece a glass epoxy PWB with green resist on the F surface and with no resist on
R surface.
[2] Place the mode selector switch in the SET position. (If the switch is placed back in the RUN position at this time, a
change of sensitivity setting will not be valid.)

[3] Place the workpiece at the specified place and press the tuning button. (1st run) (See Note 1 below.)
If the sensitivity is lower than required:
Indicator lamp (red): Blinking

Place the mode selector switch in the
RUN position. This completes the
sensitivity setting.
Change the workpiece position and setting
distance and press the tuning button again.
*If the sensor is to be retuned, keep the
mode selector switch in the SET position
and press the tuning button once again.
The digital display shows "1" again, allowing
you to perform steps from [2] to [4].

Note 1: The same sensitivity setting can be made even if the workpiece conditions are exchanged between steps [3] and
[4].

Locations of voltage measurement points and variable resistors
– DAC input voltage: Pressure sensor output voltage x 1/2
– DAC reference voltage: 1.25 V ±0.01 V
Serving as the adjustment of the nozzle vacuum measurement circuit, it is directly concerned with the measurement value of
vacuum.
1. Faulty vacuum value resulting in a pickup-and-placement motion error.
2. Reduced placement cycle time
