Adjusting The Folder Speed:
Although the folder speed has been set at the factory it may be necessary to
reset it if replacement of the control board is required. The two controls on
the board along with the speed adjust control (mounted on the right side of
the folder under the cover) will establish the minimum and maximum speed
settings. You will be able to set the speed simply by following this
adjustment procedure. Set the speed adjust control to minimum (all the way
counter-clockwise). Adjust the Min Pot-P2 until the folder just begins to
move and then back down until the folder stops moving. This sets the low
speed. Turn the speed control to max (completely clockwise) and adjust the
Max Pot-P1 to the required speed according to the specs, which is approx.
110 IPS. This sets the top speed and it is always a good idea to check the
low speed again just in case by turning the speed control all the way down
again. If everything works as expected then you are done with the
adjustment.
