2912 Hopper Level Control
INTRODUCTION
The #2912 Hopper Level Control is designed for use with
any conveying system that carries free flowing feed.
The Control automatically starts and stops the fill
system as the feed level against the paddle changes.
The #2912 Control
may be used with or without the high
differential shield. The shield increases the feed
differential of the Control by approximately 5 inches,
to reduce short cycling of the delivery system motor.
If
the delivery system operates on demand, without a
time clock, another hopper may empty faster than the
last one. It may be necessary to install a second
#2912 Control in the other hopper to insure an ample
feed supply. Wire the two Controls in parallel so that
either can start the fill system.
INSTALLATION
Install the Control in the last hopper
which is located
at the end of the delivery system. Mount it low so
that the feed level will be lower in that hopper than
in the others. The lower feed level will cause the
system to start frequently enough to maintain feed
in every hopper. Position the feed drop tube to deliver
feed into the center of the hopper in front of the
paddle. Position the drop tubes in the other hoppers
high so that they fill up but do not overflow.
Mount the Hopper Level Control vertically, as shown
in Fig. 1, to assure free movement of the switch
paddle. Drill two 9/32" holes at the desired location.
Use the bracket as a guide to determine the hole
spacing.
