Maintenance Schedule, Motors
DC Motor Brush Maintenance
All motors used to power the conveying surfaces of the Best Reach Rigid Roller and Best
Flex conveyors are DC permanent magnet motors. These motors have a pair of
serviceable brushes that wear with use. Brush life is affected by the speed of the motor,
the loads being conveyed, the number of start-stop cycles and other factors. Therefore,
brush life will vary from application to application.
To ensure long motor life, brush inspection should be included in the normal maintenance
schedule of the conveyor. Brushes should be periodically removed, visually inspected and
measured.
The brushes are accessed by removing the two caps on the end of the motor opposite of
the gearbox (see photo 1 on page 8). With the cap removed, the brush may be removed
from its holder by pulling on the spring. Visually inspect the brushes for chips or grooves.
The shunt wire should not be frayed or broken. The brush should be replaced if it
measures 0.125 inches or less as shown in Figure 1. Possible armature damage could
result from running the brushes beyond this wear point.
When being installed, the brush should slide freely into the holder. The brass contact
connected to the top of the spring should be installed so its tabs are aligned with the motor
shaft (photo 2). One tab should be facing the rear of the motor and the other tab toward
the front. The tabs should go easily into the brush holder. Do not over tighten the plastic
cap that holds the brush in place.

Installation
Unloading Units
1) Upon arrival all conveyors will be secured with wood blocks mounted to the trailer floor.
All wood blocks must be removed prior to moving the conveyors.
2) Warning: Conveyors must not be picked up utilizing forks on the rear of the unit. Failure
to adhere to this warning may cause damage to the main electrical panel on the back of
the unit, or the electrical connections coming into this panel. This damage will not be
covered under warranty.
3) To unload, the unit may be either manually pushed from the front of the conveyor, or by
utilizing a lifting strap placed around the rear frame of the conveyor and attached to a
forklift. If using the strap method, make sure that the strap does not come in contact
with any electrical wiring under the conveyor.
4) The steering actuator on the front axle of the conveyor has been disconnected for ease
of movement. When using either unloading method, someone must manually steer the
front of the unit to prevent damage to the front control panel.
Installation
Installation should only be performed by Best Conveyor Installers or qualified personnel, and
must be completed in accordance with all applicable codes and regulations.
1) Locate and mark the center of the spur. Chalk a line from the dock leveler back
approximately 50 feet. Measure 2 inches off each side of the centerline, this will give
you the inside dimension on track placement location, 5 inches off the center will give
you the outside line placement. NOTE: It might be helpful to cut 2, 4-inch blocks.
Center these blocks on your chalk line at the front and back of each piece of track, so
that you have 2 inches on either side of the line. Proceed to assemble the track as
instructed below.
2) Mark location for the front of floor track as shown on supplied application specific
drawing (if you do not have this drawing, please contact the factory.)
3) Locate and position the individual pieces of floor track as shown on drawing A.
4) Assemble the rear sections of floor track as shown in drawing B.
5) Position and anchor floor track starting with the front and aligning the inside edge with
the 2-inch or 5 inch measure out, or utilize your cut blocks for this placement.
6) Pull 2 lengths of SO cable (50’ 18/10 and 60’ 14/4) through flexible wire carrier.
7) Attach the included connection brackets to each end of the flexible wire carrier. These
parts and hardware are shown in Drawing C on page 14.
8) Feed both lengths of SO cable under rear wire cover (C channel illustrated in Drawing B
on page 13 Item # 7) exposing approximately 10” at the rear of the floor track. Attach
the flexible carrier to the wire cover (C channel).
9) Install 2 cord grips (not included) in 7/8 holes of 8x6x5 junction box that is provided.
(continued)

Installation (cont.)
10) Feed Approximately 10” of the SO cables thorough the cord grips and install junction
box on floor toward the rear of the floor track. Box should be held off the ground
utilizing Uni-strut or some other suitable material. This material is not included and will
need to be provided by the installer.
11) Pull slack cable through the opposite end of the flexible wire carrier.
12) Lay flexible wire carrier flat in the floor track.
13) If the conveyor is going to be installed from the dock end of the floor track, the stop
bar must be removed from the conveyor. If the conveyor is to be installed from the
rear of the floor track, the stop bar and the UHMW guide roller must be removed from
the conveyor.
14) Roll the conveyor into position on guide track and re-install stop bar and guide roller.
15) Connect Flexible wire carrier to the underside of the conveyor.
16) Route and secure 14/4 SO cable into main electrical enclosure box and terminate as
shown in Diagram B on page 21, connecting to the L1, L2, L3 and ground contacts.
17) Route and secure 18/10 SO cable into 12” x 12” box, and terminate as shown in
Diagram A on page 20.
18) Terminate wires from both SO cables in the floor junction box as shown on page 18.
Supply line voltage, as shown on the nameplate to 14/4 SO cable junction in floor
track junction box. This line voltage must be connected to a separate fused
disconnect rated at no more than 15 amps. This connection is shown as an option on
page 19, or may be provided by the installer. Conduit, straps, wire, hardware, etc. that
are used to connect the floor track box to the disconnect must be provide by the
installer. All wires that are pulled must be labeled to correspond to those in the floor
track box. The remaining 18/10 SO cable wires are interlock connections and should
be connected as shown in the optional disconnect stand drawing on page 19. Connect
applicable interlock wires to 18/10 SO cable in 8 x 6 x 4 junction box.
19) Remove chain guard and install and tension the chain.
20) Install the Herringbone transition to the end of the fixed feeder conveyor.
21) If purchased, install the full-line read assembly to the rear of the Transition plate as
shown on page 71-72. The wheel bracket should be attached to the plate and the
wheel should ride on the conveyor bed. When assembling the wheel bracket, be sure
not to over tighten this assembly. The wheel should roll freely within the bracket.
22) Electrical connections to the proximity switch on the full-line read must be made as
shown on page 74. The wire from the switch must be secured to the transition using
standard wire ties. Be sure to leave a little slack in this wire, so that it is not pulled too
tight. The box for this connection is not included and must be provided by the Installer.
23) The power and signal wire must then be routed back to the disconnect stand and
secured to their corresponding numbers on the terminal strip. These wires must be
ran in some type of electrical conduit, which is normally attached to the fixed feeder
conveyor. Conduit, straps, wires etc. are not included and must be provided by the
installer. These wires also must be numbered to correspond with the listed numbers
on the drawing on page 19.

Operating Instructions
An emergency stop circuit controls electrical power to all parts of the conveyor. When any
one emergency stop switch or optional cable pull switch is activated, power is removed
from all motors and actuators stopping all movement of the conveyor frame and roller bed.
All electrical power is also removed from the motors and actuators when the DOOR
DISCONNECT HANDLE is in the OFF or OPEN positions.
ENERGIZE THE MASTER CONTROL CIRCUIT:
• Make sure the door to the main electrical enclosure is closed and the DOOR
DISCONNECT HANDLE is in the ON position.
• Both EMERGENCY STOP switches (one on the door of the MAIN CONTROL
PANEL and one on the OPERATOR’S PANEL) must be in their out position. If
depressed, twist the switch’s knob to allow it to return to the out position.
• If the optional CABLE PULL stop switches are installed, both must have their
RESET BUTTON depressed and the cable pulls tensioned in their RUN position.
• Press either RESET button (one on the door of the MAIN CONTROL PANEL and
one on the OPERATOR’S PANEL) to energize the master control circuit. The
CONTROL POWER INDICATOR light will be on when this circuit is energized.
MOVE CONVEYOR INTO POSITION:
• Make sure the operator is the only person near the conveyor before moving it.
• Make sure there are no obstructions in the path of the conveyor.
• Push the joystick (located on the OPERATOR’S PANEL) down to drive the unit
forward into a truck. A bumper bar is provided on the discharge end of the
conveyor to stop the forward travel if there is an obstruction in the path of the
conveyor. Forward travel will stop when this bumper is depressed. The unit will
still drive in reverse with this bumper depressed. Pulling the joystick up will drive
the unit in reverse toward its parked position. Pushing the joystick to the
operator’s left will steer the unit to the left when it is traveling forward toward the
dock door. Right will move the conveyor right when traveling forward.
• Releasing the joystick will stop the conveyor’s movement.
TURN ON CONVEYOR BED:
• Check to make sure all personnel are away from the conveyor bed.
• Press the BED ON/OFF button on the OPERATOR’S PANEL.
TO STOP THE CONVEYOR BED:
• When the bed is running , press the BED ON/OFF button on the operator’s panel
• Pushing either emergency stop button will stop conveyor and traversing motor.

AC Tech Frequency Drives
Frequency Drive for Traversing Motor
The Best Reach Rigid Roller’s traversing motor uses a 2 HP AC Tech frequency drive,
model SF420 for 480V systems and model SF220 for 230V systems, to provide a soft start,
programmable accel and decel times and braking.
Control wiring used for this drive is the ALTERNATE TWO-WIRE START/STOP CONTROL
found on page 20 of AC Tech’s SCF Series manual. In order for the drive to function
properly in this mode, a jumper must be in place between the drive’s TB-2 terminals 1
and 2. Forward and Reverse are controlled by the Best Reach’s PLC relay outputs wired
to the drive’s TB-2 terminals 2 (common), 12 (forward) and 13A (reverse).
The AC Tech drive is field programmable. The following list shows the parameters that are
programmed before being shipped with the Best Reach unit. All parameters not shown in
this list remain set to the factory defaults.

This frequency drive has built-in over current protection. If an over current fault occurs,
the drive will shut off current to the motor and will display “PF”. While this error code is
displayed, the conveyor cannot be driven. The frequency drive will reset itself after
approximately 30 seconds. The conveyor can be driven after this reset time if the
conditions that caused the fault have been removed.

Troubleshooting: Conveyor Bed
To use this guide, find the heading that best fits your conveyor’s condition and check the
numbered items in the order they appear. It is important to proceed in the order given
since it is assumed at each item that all preceding items under that heading have passed
inspection.
CAUTION:
Electrical systems should only be serviced by qualified personnel. Refer to and observe all
local codes and OSHA regulations for the control of hazardous energy (LOCKOUT
TAGOUT). Make sure all power has been disconnected before opening any enclosure.
Keep hands and tools away from electrical circuits when power is applied.
DIAGNOSTIC LEDs
To aid in troubleshooting, there are a number of LEDs mounted on the power supply printed
circuit board (PCB) in the larger enclosure on the first leg of the system, and on each accumulation PCB in the smaller enclosures located at each motor. These LEDs are shown on the
system wire connection diagrams and their meanings are listed here.
POWER SUPPLY BOARD (LEDs AND NEON LAMP):
RED
GREEN
LARGE AMBER
SMALL AMBER
NEON LAMP
N/A

NO ZONES RUN:
1) Check AC power coming into conveyor.
a) Make sure the power supply board has 115VAC on its input terminals.
b) Check the circuit breaker mounted inside the main electrical enclosure. If the circuit
breaker is tripped, the fault causing this condition must be cleared before continuing.
c) AC power can be verified with an appropriate voltage meter across the L1 and L2
terminals on the DC Control board.
(continued)
25
Troubleshooting: Conveyor Bed (cont.)
2) Check DC control voltage.
a) Check that the Green LED on the power supply is on. If LED is off and AC voltage is
present, check the ¾ amp and 2 amp fuses on the power supply board. If a fuse is
blown, repair any electrical shorts or overload conditions before continuing. If fuses
are not blown and the GREEN LED is not on, the power supply board has failed
b) If the GREEN LED is on, check for DC voltage at accumulation zones. If DC power
is present, LEDs on photoeyes should be lit. The AMBER LED on the accumulation
board should also be lit when that zone’s photoeye is blocked. If these LEDs are not
on, make sure all communication cables are plugged in. Check the communication
cable between power supply board and first zone accumulation board.
3) Check for AC power coming into the DC motor controller.
a) The neon lamp on the power supply board should be on whenever AC power is
supplied to the DC controller. If this lamp is off, and the RED LED on the power
supply board is also off, check the 15A fuse on the power supply board that powers
the DC controller. If this fuse is good, the relay on the power supply board is bad.
b) Check the AC fuse on the DC motor controller.
c) AC power can be verified with a voltmeter at the DC controller.
4) Check for DC power on the output side of the DC motor controller.
a) Check the DC fuse on the DC controller. If the DC fuse is good, the plug-in resistor
is in play and no DC voltage is present at the output of the DC motor controller, the
controller has failed. If the fuse is blown, the cause could be either a shorted
conductor, a motor drawing excessive current or a defective DC control unit.
ONE OR MORE ZONES WILL NOT RUN:
1) Check accumulation board for control voltage.
2) Check zone’s photoeye for proper functioning.
a) Observe photoeye’s LEDs. They are powered from the accumulation’s control
voltage. If none are on, the photoeye may not have power. Control voltage is
supplied to each accumulation board by the communication cable connected to the
previous modular connector. Check cable for broken wires or defectiveconnectors.
b) Block that zone’s photoeye. The AMBER LED on the accumulation board should
come on when the photoeye’s beam is broken
3) Verify Photoeye is properly aligned with reflector across bed (if applicable).
4) Check for DC voltage at the motor cable’s connector on the accumulation board.
a) If no voltage is present, check fuse. If the fuse is blown, check for shorts in the
motor cable and in the motor.
b) If voltage is present at the motor cable’s connector, the motor or cable is defective.
ONE PHOTOEYE STOPS TWO OR MORE ZONES:
1) Check photoeyes in zones that stop when the next zone’s photoeye is blocked.
2) Verify communications cable is secured.
3) Check alignment of photoeye and across bed reflector.
26
(continued)
Troubleshooting: Conveyor Bed (cont.)
WILL NOT SHUT OFF WHEN PHOTOEYE IS BLOCKED AND NEXT ZONE IS OFF:
1) Check photoeye for proper function.
a) Make sure the accumulation’s AMBER LED is on when the photoeye is blocked. If it
does not come on, check the connections from the photoeye cable at the board’s
connector. The photoeye could also be defective.
CAUTION: Always LOCKOUT/TAGOUT the electrical power before working on the unit or
opening any electrical enclosures. Never operate the conveyor with the enclosures open.
Conveyor Host System Interface:
A set of dry contacts, normally open, are provided to give an interface signal from the Rigid
Conveyor to a host control system. The normally open contacts will be closed anytime one
or more zones of the BEST/FLEX Accumulation conveyor are running. A terminal block for
these contacts is provided in the 12 x 12 x 4 enclosure mounted over the rear axle. If host
system signal is on when the bed is in operation check the following:
1) Verify that the transition-mounted wheel is rolling on top of the bed.
a) If wheel floats above bed when picked up, loosen fork mounts slightly and retest.
b) If wheel rolls properly on the bed, verify that the proximity switch is functioning by
observing a red flashing light on the switch as the wheel turns.
c) If no flashing light is observed, verify that wiring is correct and that wire number 29
has 120VAC.
d) If power is available and the light is not observed, verify that the proximity switch is
approximately 1.5 to 8 mm away from the screw faces mounted into the wheel face.
2) Verify that the Full Line Read proximity switch mounted on main suspension system is
contacted with floor track channel when unit is fully extended.
3) Verify signal at interface is at 120VAC when bed is operating.
4) Verify connections are secure (including communications cable) in 12 x 12 x 4 electrical
enclosure under rollers located near main electrical enclosure.
UNIT WILL NOT DRIVE FORWARD OR REVERSE:
1) If the unit will not drive forward or reverse, but the beeper still sounds, push the E-Stop
button in. System will turn off. After approximately 20 seconds, release the E-stop by
turning clockwise and releasing. Push the Reset button and system should reactivate.
Unit should drive forward and reverse.
2) If the unit will not drive forward and/or reverse and the buzzer will not sound, verify that
unit has not reached one end or the other of the floor track. If unit is not at the end of
the floor track, verify that the proximity switch that controls the forward/reverse stops is
notcontacting items on the floor, or the floor itself. If the feeler is contacting the floor, the
feeler may need to be adjusted.
