[1-3] Checking the Conveyor Parallelism and Linkage Chain Tension
1) Adjust the conveyor width to the width of a Fuji PCB.
2) Verify that the difference in width from the conveyor's entrance to exit (at each module) is within
0.5mm. Record the measured values on the record sheet.
3) Verify that a linkage bracket is present (for conveyor linkage) at the secondary conveyor rails of each
module.
4) Verify that the linkage chain tension is as prescribed.
Note: If the chain is too tight, the handle will not turn easily.
[1-4] Connecting power cable and an air hose, and transmitting F4G.

After ensureing 200V is on in the transformer, connect power cable to power box.

[Chapter 2] Static Accuracy Measurement
[2-1] X, Y Axes Straightness Measurement
1) Place a right-angled jig on the conveyor in a position that is parallel (approximately) with the X and Y
axes.
2) Mount a dial gauge holder shaft on the end of the placing head, then measure the Y-axis straightness
while moving the head by hand in the Y-direction.
Y-axis movement distance (mm)
Tolerance: 0.03 / 400 (mm) Y-measurement value: / 400 (mm)
3) Measure the X-axis straightness while moving the head by hand in the X-direction.
Tolerance: 0.03 / 400 (mm) X-measurement value: / 400 (mm)
