Board Stop In
Sensor
The Board Stop In Sensor is mounted on the camera carriage and has an LED
mounted in its body which illuminates when the beam is broken.
When the board stop is home (raised) the LED is on as the beam is broken by
the vane. The only adjustment is on the opto pillars which must be set to enable
the beam of the opto to look through the slot of the vane giving definite up/down
detection.
