Installation
The mounting bolts used must be of grade 8 material. When installing the
motor, it is necessary to use locking nuts (do not use split lock washers) and
tighten the bolts evenly to the recommended torque ratings. Never reinstall
used fasteners as they may fail under load. Check the bolts for security after a
few hours of operation.
It is imperative that the eccentric weights at both ends of the shaft are adjusted
identically: “mirror images of each other.” When adjusting the eccentric
weights, use the least amount of amplitude and force to move your material.
This will provide longer motor life. See the “Eccentric Weight Adjustment”
section.
The motors are supplied with a terminal block to provide safe and secure lead
attachment. Wiring of these motors must be done in accordance with the
National Electric Code. See Figures 2 through 6 for wiring diagrams. Each
motor is supplied with a wiring diagram inside the terminal box.
Always use closed loop wire connectors only with crimped or soldered
terminal ends on cable leads. See Figure 1 for the correct technique for
assembling the wire connectors. Reinstall the foam rubber blocks supplied in
the junction box on top of the cable leads.
When wiring the motor, always use the ground connection.
CAUTION
!
Never weld on the bin or structure without first disconnecting
the motor leads. Failure to do so may cause damage to the
motor windings and bearings by grounding through the
motor.
IMPORTANT
Overload Protection Required!
This vibrator carries the best guarantee offered by any
vibrator manufacturer. To assure extended life, maintain the
warranty, and comply with the National Electric Code, this
unit must be wired with the proper size overload protection.
Install overload protection in the vibrator circuit in
accordance with Article 430, Part III of the National Electrical
Code. If the vibrator cannot be operated in your application
at this amperage level, consult Metalfab, Inc. or your local
distributor. Do not increase the overload protection rating.
This may destroy the vibrator and will void the warranty.
