The shaft-with-eccentric-rotor must be taken out of the hopper shaker assembly for mounting.
To remove the shaft, loosen the two collars (set screw + turn), and loosen the bolts on the second pillow block bearing, and disconnect the coupler (bolt pin + set screw) from the shaker motor.
Mount the hopper assembly on the rear hopper supports, with the shaft in place through the hole.
Attach the hopper shaker to the second rear support with the provided connecting piece.
Tighten the shaft - start with the pillow block bearing and the shaker motor bolts. Tighten the motor bolts and pillow block bolts gradually, so that the shaft remains aligned and does not stiffen up. You should be able to turn the eccentric by hand easily once everything is tightened. If the eccentric does not spin freely, then loosen and retighten the bolts. Make sure that the shaft does not touch the hopper sheet, otherwise adjust the rear hopper sheet position.
Tighten the rear hopper supports, rear hopper sheet, shaker motor, and shaker motor shaft.
Attach assembly to the second solenoid from the left.
One plain hose goes directly from the base of the secondary cylinder to port B of the solenoid, and the more complex assembly screws into the rod-end-port of the secondary cylinder, with the opposite end of this hose assembly screwing into port A of the second solenoid. (picture)
Attach the sensor to the a Arduino shield in the controller box.
Run the wires into the controller box's right-hand knockout.
Pay attention to the fragile connection ends (they break easily). Connect them to the appropriate pins on the Arduino shield by unscrewing the terminals, putting in the lead, and tightening the terminal down.
Do not overtighten, or you may break the leads.
Pull on the lead to make sure it is connected securely.
The pins of interest on the Arduino shield are A5, A4, and A3 - left-hand-side terminals - which accept the blue (signal) wires of the sensors - for the main cylinder, secondary cylinder, and shaker motor sensors, respectively. For the remaining leads, the blue/white lead is the ground, and the orange/white lead is 5V.
Connect the ones for the main and secondary cylinder on the bottom of the shield - into any available slots, as determined by convenience. For the shaker motor, connect the ground and 5V on the top side of the shield. While the signal leads need to be attached to the exact slots, any ground or 5V pin will work for the remaining wires - and may be selected by convenience of location. The useful part about the Arduino shield is that it has a large number of slots for convenience.
