Chore-Time 28999 User manual
Introduction
The 28999 Drop Feeder Control is designed to be used
with a Chore-Time Drop Feeding System and Chore-
Time Flex-Auger®System.
The control will automatically open the Drop Feeders,
close the Drop Feeders, and start the fill system. The
system may also be operated manually.
The components of the control are housed in a dust proof,
water tight box. Liquid tight connectors must be used
when wiring into the control. The cover must be latched
in closed position unless switches or time clockis being
adjusted.
Wire the Drop Feeder Control, according to the
appropriate wiring diagram.
Setting the Control
Unlatch and open front cover.
Time Clock operation
Set the desired feeding time(s) on clock by sliding out sufficient tabs to allow for auger run time. Slide out one
additional tab for drop cycle (time required to open drops and close drops). Each tab represents 15 minutes. See
“Time Clock Features and Operation” on page 5 for clock setting information.
The lower toggle switch should be in the TIME CLOCK OPERATION position.
The upper toggle switch should be in the OFF position.
How it Operates
When the switch on the time clock is activated by the tabs, all drops will open at the same time. The drops will
automatically begin closing 15 seconds to 5 minutes after the clock is activated. This delay is adjustable
inside the control panel.
In multiple lift applications the #1 lift will completely close, then #2, etc. until all drops have closed. At that
time the fill system contactor and AUGER ENABLED Pilot Light will become energized and the fill system
auger(s) will refill the drop boxes. The switch in the Drop Feeder Control Unit will stop the fill system(s).
The fill system contactor and AUGER ENABLED Pilot Light will remain energized until the tabs no longer
activate the Time Clock Switch.
CAUTION: Only use the number of time clock tabs needed to fill the system plus one extra tab.
Manual Operation
Set the lower toggle switch to the MANUAL OPERATION position. The Time Clock is now disabled and the
drops may be opened or closed using the upper toggle switch.
The upper toggle switch should be in the OFF position when not in use.

How it Operates
Set the upper toggle switch to the OPEN DROPS position and the drops will open. Set the upper toggle switch
to the CLOSE DROPS AND FILL position, and the drops will close. When the balls are fully seated the fill
system contactor and AUGER ENABLED Pilot Light will become energized. The switch in the Drop
Feeder Control Unit will stop the fill system.
Close the cover and secure latch to keep moisture and contamination from entering box and voiding warranty.

Internal Wiring Changes for converting a standard 28999 Drop Feeder
Control Panel to a Feed-Delay Fill style control
In this mode of operation the drops will be full of feed at feeding. The refilling will be delayed to a preset time of
choice. After the balls have been lifted to allow feeding, the ball will remain in the up position until time to refill
the feed boxes.
The control will need to be wired as shown to run as a delay fill system, See Figure 1.
Figure 1. Standard Control converted
Instructions for setting the time clock, See Figure 2. Push in all the tabs between the selected feed time and fill
time. With the time clock set this way it will delay filling of the boxes.

Time Clock Features and Operation
• The outside edge of the clock face is a series of tabs.
• Use a finger nail of small screw driver to push tabs out.
• Each white tab on the time clock is equivalent to 15 minutes.
• Turn the white minute hand clockwise until the real time (actual time of day) is lined up with white arrow on
inner clock face.
•Do not turn the hand counter-clockwise! This will strip out the nylon gears and void your warranty.
Also, never adjust the time clock by turning the outer dial.
