ADJUSTMENT
Masking travel is stopped automatically in the up and down positions by limit switches that are properly adjusted at
the factory. Should it be necessary to adjust the stop positions, proceed in the following manner using a small flat
screwdriver or a 5/32" allen wrench. Access to the switches is provided by holes on the top left side of the Pro
Imager. Refer to figure 4.
UP LIMIT CONTROL
The up limit controls the stop position when the mask is traveling up,
or unmasking the screen. Set the Pro Imager to the down, or masked
position. Turn the up limit control
CLOCKWISE to DECREASE the up
travel. Turn it COUNTER-CLOCKWISE to INCREASE the up travel. Turn
the control a quarter turn at a time and then run the Pro Imager to
check the stop position. Repeat the above steps until the desired po-
sition is reached.
NOTE: The bottom of the slat bar should be no more than 1/8" above
the edge of the frame while in the up position. See figure 2.
