Operating Instructions
The chamber, including cover and sweeper arm, may be removed from the drive mechanism
for cleaning and animal husbandry.
1. Orient the chamber on the base so the sweep arm carriage is facing the drive mechanism.
2. Align the top slot of the sweep arm carriage
(3A) with the drive pin extending from the
bottom of the drive mechanism (3B). This
is done by sliding the sweep arm carriage
until the slot lines up with the pin as shown
at right.
3. Loosen the thumbscrew (4) on each side of the uprights and slide the chamber between
the uprights and beneath the drive mechanism until stopped by contact between the
chamber cover wings and the uprights. The pin extending beneath the drive mechanism
fits inside the slot on top of the sweep arm carriage.
NOTE:
The drive pin extending from beneath the drive mechanism must be located within
the slot on top of the sweep arm carriage. If the drive pin is not engaged with the carriage
slot, then the sweeper arm will not operate.
4. Lightly tighten the thumbscrews on both uprights against the sides of the chamber.
NOTE:
The thumbscrews are not intended to be a “lock” but rather a restraint to prevent the
chamber from moving side-to-side due to reversing motion of the sweeper arm. It is also
intended to prevent the chamber from “walking” out from under the drive due to vibration.
The ends of the thumbscrews are intended to be adjusted right up to the plastic face of
the chamber but not to exert any significant pressure on the sides. If the thumbscrews
are flexing, they are too tight.
5. Turn the cycle time selector switch to the desired cycle time.
6. Use the provided 9 VDC power supply and connect it to the power connector on the side
of the drive mechanism.
7. Turn the power on by pressing the power button on the side of the drive mechanism.
Power ON is indicated by a green light adjacent to the power button.
8. Upon power turning on, the sweeper arm will move to the home location at the wall nearest
the food and water support. Once at the home location, the unit will begin its first sweep
and the cycle timer will start timing.
9.
To change the cycle time, first turn off power by pressing the power button. Make the
necessary change, and turn power back on.
NOTE:
Changes to the cycle time when the unit is turned ON will result in an unpredictable
first sweep. After the first complete cycle, the sweep intervals will reliably follow the new
set value. This unpredictable first sweep may be avoided by simply turning OFF the power
(recommended) when making changes to the cycle time value.
