5-4. Replacing the IN and OUT Sensors
Bind the cables A and B with binding bands, taking care that they are not pulled or loosened
excessively during adjustment of sensor position.
Figure 5-4-1 IN and OUT Sensors
<Adjusting the sensitivity>
1) Make an adjustment so that a (matte) black glass epoxy PWB placed on the transport path can
be detected.
2) Place a (matte) black glass epoxy PWB under the sensor and rotate the sensitivity adjustment
knob of the sensor counterclockwise. Then gradually rotate it clockwise up to the position at
which the specified PWB is detected.
∗ If any black glass epoxy PWB is not available, use the PWB having the darkest color of those to
be used.

5-5. Replacing the WAIT, STOP, and C-OUT Sensors
Figure 5-5-1 Placement of Sensors (Left → Right Transport)
5-5-1. Replacing the Fiber
1) Remove the fiber from the transport rail.
2) Lay down the fiber fixing lever of the sensor amplifier to pull
out the fiber.
3) Detach the fiber from the WAIT sensor bracket.
4) When installing new fibers, reassemble the
components in the order of step 3) to 1).
∗ Insert the fiber until it reaches the far position of the
amplifier unit. For the fiber insertion length, refer to
the reference mark for the fiber insertion length.
∗ After replacement, perform the steps described in section 5-5-3, "Adjusting the Sensitivity of
the WAIT/STOP/C-OUT Sensor".
5-5-2. Replacing the Amplifier Unit
<How to mount the amplifier unit>
1) Insert the groove (part A) on the front of the amplifier unit into the DIN rail.
2) Push the rear of the amplifier unit (part B) to fit it completely.
<Detaching the amplifier unit>
1) Push the unit strongly forward (c). The front lock is then released.
2) As shown in the Figure, pull up the unit (d) to detach it.
∗ After replacement, perform the steps described in Subsection 5-5-3, "Adjusting the Sensitivity
of the WAIT/STOP/C-OUT Sensor".
