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 clock is 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.
