How to replace consumable parts
r
Attach the board clamp plate.
Fit the board clamp plate into its original
position and tighten the board clamp plate
mounting bolts with a hex wrench (3).
t
Check the belt rotating condition.
1. Make sure that the board clamp top
surface is approx. 0.5 mm lower than the
belt upper surface.
2. Close the machine safety cover and
cancel the emergency stop. Attach the
carriage if the machine is the carriage
type.
3. On the [Unit]-[Conveyor] screen, press
the [Conveyor In] button or [Conveyor
Out] button to turn on the conveyor
motor and check the belt rotation.
4. If the rotation speed fluctuates or there is
slack in the belt, adjust the position of
the tensioner bolt and then check the
rotation again.
c
CAUTION
When the difference between the belt upper surface
and board clamp top surface is very little, the board
transfer error may occur easily. In this case, contact
your distributor.
n
NOTE
If U-axis is moved manually, an error may occur when
changing the conveyor width after the work.
In this case, see "2.3.1 Checking conveyor sensor
condition and operation" in chapter 3 to perform the
conveyor sensor tuning.
