Indicator:
Indicates the current position of the sensitivity adjustment trimmer.
One turn of the trimmer changes the pointer position by one division
on the indicator scale.
MAX
Sensitivity adjustment trimmer (8-turn):
Turning the trimmer clockwise increases the sensitivity. Turning the

Indicator
3.1 Turn the sensitivity adjustment trimmer clockwise. Find point A
at which the operation indicator (red LED) illuminates.
3.2 Place a .015 to .024 inch (0,38 to 0,6mm) diameter jumper wire
on the chain and move the chain so that the jumper wire is in the
path of the light beam between the transmitting and receiving
fiber optics. Note that the operation indicator (red LED)
extinguishes.
3.3 When the operation indicator (red LED) is extinguished, turn the
sensitivity adjustment trimmer clockwise to find point B at which
the operation indicator illuminates.
3.4 When the operation indicator (red LED) is illuminated, turn the
sensitivity adjustment trimmer counterclockwise to extinguish
the indicator. Then, turn the trimmer clockwise to find point B at
which the operation indicator illuminates.
3.5 Set the sensitivity to the point midway between points A and B.
NOTE
If the sensitivity difference is smaller than one division on the indicator
scale, adjust the sensitivity based on the position of the sensitivity
adjustment trimmer. If there is a difference of a least a half turn between
points A and B, stable detection is possible.

Tensioning Head Chain Belts
The head chain belts are designed with built in tensioning mechanisms.
Whenever the belts are suspected of being loose due to stretching or have
been replaced, perform the following procedures to set the belt tension.
Drive Belt
Purpose:
To correctly tension the head chain drive belt.
Procedure:
1. Palm the machine down as detailed in the Operation Reference
Manual.
2. Loosen the four cap screws that secure the head drive motor to the mo-
tor mounting bracket. Loosen the screws just enough to allow the mo-
tor to move
3. Physically move the motor to ensure that the motor is pushed along the
mounting surface away from the spring.
4. Tighten the four cap screws that secure the head drive motor to the mo-
tor mounting bracket.
End of procedure.
Idler Belts
Purpose:
To correctly tension the head chain idler belts.
Procedure:
1. Palm the machine down as detailed in the Operation Reference
Manual.
2. Loosen the cap screw that secures the idler plate to the motor housing.
Loosen the screws just enough to allow the idler plate to move
3. Tighten the cap screw that secures the idler plate to the motor housing.
4. Repeat this procedure for the idler belt on the opposite side of the in-
sertion head.
End of procedure.

Purpose:
The centering mechanism centers the components in the head chain two
chain index positions prior to insertion. The following procedures ensure
proper operation of the centering mechanism.
Prerequisite:
Head Drive Position Set Up
Head Chain to Tooling Alignment
Cam Orientation
Purpose:
This adjustment is used to establish the basic relationship between the center-
ing cam and the insertion tooling down stroke. This procedure should be
performed whenever the centering mechanism is reinstalled into the insertion
head housing.
Adjustment Procedure:
1. Push the STOP push button.
2. Palm the machine down as detailed in the Operation Manual.
