Control Unit & Power Unit Installation - Chore-Time FLEX-AUGER 108 Installation Instruction

FLEX-AUGER® Feed Delivery System
Control Unit & Power Unit Installation
1.Attach the Tube Anchor to the end of the Control Unit. Place a flat washer on each bolt that fastens the Tube
Anchor to the Control Unit. (See Figure 13.)
2.Attach the power unit to the control unit using the 5/16-18 machine screws installed on the face of the
gearhead and the flat washers packed with the control.
3.3-Phase Applications: Power Units/Control Units do not include all the electrical components shown.
Components must be purchased locally to match local and national electrical codes. Skip to step 4.
1-Phase Application: Connect the electrical wires on the power unit to the control unit. The power unit is
shipped with the electrical connectors attached. Flex cable is shipped with the control unit.
a) Install a red plastic anti-short bushing in one end of the flex cable. Push the anti-short bushing into the end
of the cable so that the wide lip covers the edge of the metal to protect the wire insulation.
b)Push the power unit wires through the flex cable starting in the end with the anti-short bushing. Be careful
not to damage the insulation on the wires.
c)Clamp the end of the flex cable in the 90 degree connector on the motor. Be sure the anti-short bushing is
still in place.
d)Install the anti-short bushing supplied with the control unit in the free end of the flex cable.
e)Run the motor wires through the 90 degree connector supplied with the control unit and clamp the flex cable
in the connector.
f)Attach the 90 degree connector to the control unit housing.
g)Attach the insulated motor wires to the terminal block in the control housing: one wire to terminal three (3)
and one wire to terminal four (4). Attach the bare grounding wire to one of the green colored screws
provided for bonding the grounding wires.
4.Place a tube clamp on the Tube Anchor and connect the Control Unit/Power Unit assembly to the end of the
FLEX-AUGER tube.
Note for steel systems: The Tube Insert must be inserted in the Tube Anchor Weldment.
Note: The switch in the control unit is a safety back-up switch in case the feed level switch fails to shut off
the system. DO NOT use the safety switch to control the FLEX-AUGER System, as feed will bridge in the
control, and the motor overload will trip.
