Proximity Switch Adjustment - USC LPX Series Operator's Manual

The proximity switches mounted in the
extension ring and cone of the seed treater
detect when seed is present.
The proximity switch located in the extension
ring is used to automatically shut off the inlet
conveyor when the surge hopper is full. This
proximity switch is not present on tower
systems.
The proximity switch mounted in the cone
automatically shuts off the pump when all
seed has left the hopper.
Sometimes these proximity switches do not
work properly. This can be caused from wear,
dust, or even moisture. The first step is to
clean the lens of the proximity switch. If this
does not solve the problem, the next step
would be to adjust the sensitivity of the
proximity switch.
Using the small screwdriver provided inside the control panel, you can adjust the
proximity switch by turning the adjusting screw on the back of the proximity switch.

Turn Clockwise to make the proximity switch more sensitive.
