Lift Cylinder Proximity Switch Adjustment
There are three proximity switches on the lift cylinder. They sense the position of the
cylinder piston, and therefore the bottom of the lance, in relation to the hopper fluidizing
plate, the bottom of a powder box, and the purge manifold. Each switch has an LED that
turns on when the switch is closed through the use of a magnet embedded in the cylinder
piston.

NOTE: The lance assembly will stop at the Box or Hopper switch, depending on the
powder source selected. To override the switch, continue to hold the Lance Control
switch in the down position for 3 seconds after it stops.
LS308 Purge Switch (Bottom Switch): Lower the lance down onto the stop bolt. Slide
the switch up and down while watching the LED. Mark the positions at which the switch
LED turns on in both directions, then secure the switch midway between the on positions.
LS307 Box Switch (Middle Switch): Position an empty powder box on the table. Lower
the lance assembly down until it is at the recommended height above the bottom of the
box. Slide the switch up or down until the switch LED turns on. Mark the positions at
which the switch LED turns on in both directions, then secure the switch midway between
the on positions.
LS306 Hopper Switch (Top Switch):
Position an empty hopper on the table. Lower the
lance assembly down until it is at the recommended height above the fluidizing plate.
Slide the switch up or down until the switch LED turns on. Mark the positions at which the
switch LED turns on in both directions, then secure the switch midway between the on
positions.
