base and have mounting holes drilled to match the bolt pattern of the feeder. If a

weigh plate is provided, its platform must be located in the correct location and at the

correct height and be level. Other accessories such as a solution tank must be

properly located in reference to the feeder, while accessories such as an extension

hopper only have to be bolted into position atop the feeder. On some convenient

structure close to the feeder locate and drill holes for mounting the motor drive

controller. This location should be within a 20’ cable run of the feeder. If the

controller must be located at longer distance from the feeder a junction box and cable

extension box will have to be provided (by others). Wire the drive controller in

accordance with the National Electric, Code, State and Local regulations. See wiring

diagram provided with the feeder for basic feeder to controller connections.



Once the wiring is complete and before material is added to the feeder hopper, check

the rotation of the drive screw to make sure the screw is rotating in the correct

direction. Start the feeder and look into the feeder hopper to observe the screw

flight. If the flight appears to be advancing toward the discharge spout, the screw is

rotating in the correct direction. If you are not sure, drop a small amount of material

(enough to cover the flight) in the center of the feeder hopper and observe which

way the flight draws the material. If the material moves toward the discharge spout,

all is well. If the material moves toward the drive end of the screw, the flight is

rotating backward. Rotating backward will unscrew the flight assembly from the

drive shaft.
Stop the motor, remove AC power from the SCR controller and reverse

the two armature wires connected to the SCR terminals. If the wiring reversal is

required, check that the screw is fully threaded into the drive shaft, re-apply power to
