the auger at all times.
Part No. 36880
Introduction
The Proximity Intermediate Control w/On Delay was designed for brood applications.
The Proximity Intermediate Control uses a Proximity Switch to sense feed and cause
the system to start and stop. The Proximity Switch has sensitivity adjustment and de-
lay adjustment screws.
The Proximity Intermediate Control is to be located just prior to the brood partition.
Do not hinder bird movement around the Intermediate Control. Provide adequate light-
ing so that the birds will not shy away from the Intermediate Control.

Installation
The Auger Tube with the Intermediate Control must have each hole enlarged, as
shown in Figure 1. This will ensure total feed dropout before the Intermediate Control.
Use a hacksaw and tin snips to enlarge hole size. Be sure there are no burrs inside
the tube to catch the auger.
Install the Proximity Intermediate Control:
Remove the (2) Hex Head Screws securing the Tube Retainer on the Inter-
mediate Control. See Figure 2.
Lift off the Tube Retainer.
Cradle the Feeder Tube in the Control Housing. The Feeder Tube may have
to be turned to allow the pan to hang straight.
Clamp the Control in place by inserting tabs on the Tube Retainer into the
slots on the Control Body. Install and tighten the two hex head screws, re-
moved above.
Figure 3 shows an Intermediate Control installed in the appropriate location.

Proximity Switch Schematic
Important:
This wiring schematic represents the switch in the non-powered condition. When power is
applied the N.O. and N.C. contacts reverse.
Refer to the wiring diagrams, above, when wiring the Proximity Switch.

Operation
When the switch senses feed, the internal relay is activated immediately, stopping the
system. When feed is removed, the delay is activated and prevents the system from
starting until it has timed out.
Setting the Delay
The Proximity Switch includes an adjustable delay. The delay may be set from 1 sec-
ond to 10 minutes.
A. Use a small screw driver provided to turn the Delay Adjustment Screw (see
Figure 4). Turn the screw counter clockwise until the light stays on. Turn the
screw clockwise one complete revolution. This sets the delay to 1 second.
B. To increase the delay, turn the Delay Adjustment Screw clockwise.
Watch the indicator light; quick flashes = shorter time delay, slow flashes =
longer time delay.
Adjusting the Sensitivity
The Proximity Switch is shipped with the sensitivity preset at the factory. This setting
is adequate for most feed types and conditions. However if the sensitivity does need
to be adjusted, carefully follow these instructions:
A. Allow power to be supplied to the switch for at least 15 minutes to properly
warm the sensor. See the wiring diagrams in this manual.
B. Set the Proximity Switch time delay to 1 second as specified above.
C. Use a small screw driver to remove the caulk concealing the Sensitivity
Adjustment Screw.
D. Greater switch sensitivity is achieved by turning the Sensitivity Adjustment
Screw clockwise.
Less switch sensitivity is achieved by turning the Sensitivity Adjustment
Screw counterclockwise.
Note the screw orientation before beginning adjustment. Adjust the Sensitiv-
ity Adjustment Screw 1/4 turn, test switch, continue adjusting as required.
