Checking the Sensor Reaction
1 Press the EMERGENCY STOP button to take the 200V down to 100V.
2 Manually rotate the rotary holder to select nozzle No. 6. At this time, the sensor
reactions should be the same as shown below.
3 Rotate the rotary holder to select nozzle No. 2. At this time, the sensor reactions
should be the same as shown below.
WARNING
• Press EMERGENCY STOP before performing this procedure.
• Exercise extreme caution when working on the machine if the cam
is not at its origin (0 deg.). Spring recoil can rotate the cam inde-
pendently.

Sensor Sensitivity Adjustment
Remove the cover of the amplifier and follow the adjustment procedure below.
Note: Be careful not to drop the cover inside the machine.
Set the L-ON/D-ON switch to L-ON for the nozzle detection sensor.
1 Move the amplifier's mode change switch to the "SET" position.
2 Rotate the nozzle holder until the sensor light beam is adjacent to a dark part of
the dog and press "TUNING".
3 Rotate the nozzle holder until the sensor light beam is adjacent to a metal part
of the dog and press "TUNING".
4 Return the amplifier's mode changing switch to the "RUN" position.
At this time the sensitivity of the sensor can be checked on the digital display.
Digital display:
0 ~ 1: Stable interruption range
8 ~ 9: Stable light input range
If the display is within the stable range, setting is complete.
5 If the display is not within the stable range, check the items below and make
the necessary adjustments.
• Check the connections between the amplifier and the fiberoptic cable.
• Check the position of the sensor.
