INSTALLATION

• Conveyor Installation
1. Utilize splice angles at each intermediate bed joint.
2. Attach supports to both ends of drive section and to one end of
intermediate or tail sections. Hand tighten bolts only at this time.
Conveyor's angle of incline will determine where the knee brace mounting
brackets are to be placed when required.
3. Adjust elevation to required height.
4. Once conveyor is square and level, tighten support hardware.

• Electrical Equipment

WARNING! Electrical controls shall be installed and wired by a qualified
electrician. Wiring information for the motor and controls are furnished by the
equipment manufacturer.
CONTROLS
Electrical Code: All motor controls and wiring shall conform to the National
Electrical Code (Article 670 or other applicable articles) as published by
the National Fire Protection Association and as approved by the American
Standards Institute, Inc.
CONTROL STATIONS
A) Control stations should be so arranged and located that the operation
of the equipment is visible from them, and shall be clearly marked or
labeled to indicate the function controlled.
B) A conveyor which would cause injury when started shall not be
started until employees in the area are alerted by a signal or by a
designated person that the conveyor is about to start.
When a conveyor would cause injury when started and is automatically
controlled or must be controlled from a remote location, an audible device
shall be provided which can be clearly heard at all points along the
conveyor where personnel may be present. The warning device shall be
actuated by the controller device starting the conveyor and shall continue
for a required period of time before the conveyor starts. A flashing light or
similar visual warning may be used in conjunction with or in place of the
audible device if more effective in particular circumstances.
Where system function would be seriously hindered or adversely
affected by the required time delay or where the intent of the warning may
be misinterpreted (i.e., a work area with many different conveyors and
allied devices), clear, concise, and legible warning shall be provided. The
warning shall indicate that conveyors and allied equipment may be started
at any time, that danger exists, and that personnel must keep clear. The
warnings shall be provided along the conveyor at areas not guarded by
position or location.
C) Remotely and automatically controlled conveyors, and conveyors
where operator stations are not manned or are beyond voice and visual
contact from drive areas, loading areas, transfer points, and other
potentially hazardous locations on the conveyor path not guarded by
location, position, or guards, shall be furnished with emergency stop
buttons, pull cords, limit switches, or similar emergency stop devices.
All such emergency stop devices shall be easily identifiable in the
immediate vicinity of such locations unless guarded by location, position,
or guards. Where the design, function, and operation of such conveyor
clearly is not hazardous to personnel, an emergency stop device is not
required.
The emergency stop device shall act directly on the control of the
conveyor concerned and shall not depend on the stopping of any other
equipment. The emergency stop devices shall be installed so that they
cannot be overridden from other locations.
D) Inactive and unused actuators, controllers, and wiring should be
removed from control stations and panel boards, together with obsolete
diagrams, indicators, control labels, and other material which serve to
confuse the operator.
SAFETY DEVICES
A) All safety devices, including wiring of electrical safety devices, shall
be arranged to operate in a "Fail-Safe" manner, that is, if power failure or
failure of the device itself would occur, a hazardous condition must not
result.
B) Emergency Stops and Restarts. Conveyor controls shall be so
arranged that, in case of emergency stop, manual reset or start at the
location where the emergency stop was initiated, shall be required of the
conveyor(s) and associated equipment to resume operation.
C) Before restarting a conveyor which has been stopped because of an
emergency, an inspection of the conveyor shall be made and the cause of the
stoppage determined. The starting device shall be locked out before any attempt
is made to remove the cause of stoppage, unless operation is necessary to
determine the cause or to safely remove the stoppage.
Refer to ANSI Z244.1-1982, American National Standard for Personnel
Protection – Lockout/Tagout of Energy Sources – Minimum Safety Requirements
and OSHA Standard Number 29 CFR 1910.147 "The Control of Hazardous
Energy (Lockout/Tagout)."

• Belt Installation

INSTALLING THE BELT
The conveyor belt has been cut to the proper length and lacing installed at the
factory. To install follow these steps:
1. Thread belt through conveyor as shown on Page 7.
2. Pull ends together and insert lacing pin. (Figure 7B). If belt ends cannot be
pulled together by hand, loosen take-ups (in center drive or at tail pulley) and/or
use a belt puller so lacing pin can be inserted.
3. Adjust belt tension with take-up pulley. Keep pulley square by moving both
take-up bolts an equal amount. Maintain enough tension so drive pulley will not
slip when carrying the rated load.
4. Track belt per instructions on page 8.
5. See below for Take-up instructions.
CAUTION! Excessive slippage will reduce belt life and damage drive pulley lagging.
Never apply more tension than is needed. Over-tension will cause extra wear to belt and
bearings and will require extra power from drive.
• Take Up
Tighten Belt
1. Loosen jam nut on each side.
2. Turn the weld nut (1) Revolution on each side until belt is at desired tension.
3. Belt should drive expected load without slipping on drive pulley. Do NOT over
tension.
4. Confirm that "X" dimension is the same on each side.
5. If "X" is different, loosen larger dimensioned side and even up the two sides.
6. If "X" is same, tighten jam nut on each side.
Loosen Belt
1. Loosen jam nut on each side.
2. Turn the weld nut (1) Revolution on each side until belt tension is relaxed.
3. Follow instructions "tighten belt" to reset tension.
