6.5 Conveyor Control
Two knobs installed next to the FFC Calibration Board are used for the pulling & pushing
control.
NOTE: Please don't change the conveyor pulling and pushing speed
without TRI engineers' permission. Changing the speed arbitrarily may
cause problems hard to solve.

6.6 Digital Fiber Sensor
There are three sensors related to conveyor movement.
1) Stop Sensor: The inspected board will stop at where Stop Sensor is.
2) Deceleration Sensor: The inspected board starts to decrease its speed once it passes
the deceleration sensor.
3) Two-Stage Sensor: This sensor is used when two-stage function is activated.
The sensors will work differently according to Left-In or Right-in board direction.
a) Case 1: Left-In board condition
