6. Manually set the conveyor width (1) to 50.8 mm (2 in.).
7. Set flags on the limit switch board halfway through their optical
sensors.
8. Connect the lead screws to the drive shafts. Mesh the miter gears (7)
and tighten set screws.
Calibrating the Conveyor Width
Perform the following to calibrate the ovens conveyor width:
NOTE: Do not move the rail unless all sprockets and gears are securely
set.
1. Apply power to the oven. Enter the SET-UP SCREEN menu.
2. Measure a PCB to use as a reference. Set the ovens rail width to
that known dimension. Start the conveyor moving.
CAUTION: Before selecting product width, remove all boards
curing in the oven. Failure to observe this caution will result in
damage to equipment.
3. Touch the PRD WIDTH pad. Touch ENTER to calibrate the conveyor.
Follow the message prompts on the SET-UP SCREEN menu.
Remove all boards from within the process cavity.
