Hopper Level Control Switch
Cumberland’s feed level control switches are designed to provide automatic control for the fill system on
any hopper-fed feeding system. The switch should be mounted on the back (bearing) side of the feed
hopper, using the provided mounting hardware. Mounting the switch as close as possible to the drop from
the fill system will provide optimum operation.
The bottom of the fill system drop should be positioned in the hopper so feed will activate the switch, yet
not run over the side of the hopper. When installed, the switch must hang vertically or at a slight angle so
that gravity will cause the switch paddle to activate and close the operating circuit. Bend the mounting
bracket as necessary to accomplish this. Be careful not to deform the paddle when bending the arm.
Remove the tape from around the fabric and paddle before installing the switch in the hopper.
On installations with multiple hoppers, it may be necessary to locate the switch in the last hopper lower
than the others. This will create a “buffer area” (A) in the hopper to allow for any “carry-over” of feed from
the other drops. If there is carry-over, without this buffer, feed may eventually fill the last drop tube and trip
the control unit safety switch.
