SAFETY INFORMATION
• Installation
GUARDS AND GUARDING
Interfacing of Equipment. When two or more pieces of equipment are
interfaced, special attention shall be given to the interfaced area to
ensure the presence of adequate guarding and safety devices.
Guarding Exceptions. Whenever conditions prevail that would
require guarding under these standards, but such guarding would
render the conveyor unusable, prominent warning means shall be
provided in the area or on the equipment in lieu of guarding.
Guarded by Location or Position. Where necessary for the
protection of employees from hazards, all exposed moving machinery
parts that present a hazard to employees at their work station shall
be mechanically or electrically guarded, or guarded by location or
position.
• Remoteness from frequent presence of public or employed
personnel shall constitute guarding by location.
• When a conveyor passes over a walkway, roadway, or work
station, it is considered guarded solely by location or position
if all moving parts are at least 8 ft. (2.44 m) above the oor or
walking surface or are otherwise located so that the employee
cannot inadvertently come in contact with hazardous moving
parts.
• Although overhead conveyors may be guarded by location, spill
guards, pan guards, or equivalent shall be provided if the product
may fall off the conveyor for any reason and if personnel would
be endangered.
HEADROOM
• When conveyors are installed above exit passageways, aisles,
or corridors, there shall be provided a minimum clearance of
6 ft. 8 in. (2.032 m) measured vertically from the oor or walking
surface to the lowest part of the conveyor or guards.
• Where system function will be impaired by providing the
minimum clearance of 6 ft. 8 in. (2.032 m) through an emergency
clearance, alternate passageways shall be provided.
• It is permissible to allow passage under conveyors with less
than 6 ft. 8 in. (2.032 m) clearance from the oor for other than
emergency exits if a suitable warning indicates low headroom.
• Operation
A) Only trained employees shall be permitted to operate conveyors.
Training shall include instruction in operation under normal conditions
and emergency situations.
B) Where employee safety is dependent upon stopping and/or
starting devices, they shall be kept free of obstructions to permit
ready access.
C) The area around loading and unloading points shall be kept clear
of obstructions which could endanger personnel.
D) No person shall ride the load-carrying element of a conveyor
under any circumstances unless that person is specically authorized
by the owner or employer to do so. Under those circumstances, such
employee shall only ride a conveyor which incorporates within its
supporting structure platforms or control stations specically designed
for carrying personnel. Under no circumstances shall any person ride
on any element of a vertical conveyor.
E) Personnel working on or near a conveyor shall be instructed as to
the location and operation of pertinent stopping devices.
F) A conveyor shall be used to transport only material it is capable
of handling safely.
G) Under no circumstances shall the safety characteristics of the
conveyor be altered if such alterations would endanger personnel.
H) Routine inspections and preventive and corrective maintenance
programs shall be conducted to ensure that all safety features and
devices are retained and function properly.
I) Personnel should be alerted to the potential hazard of entanglement
in conveyors caused by items such as long hair, loose clothing, and
jewelry.
J) Conveyors shall not be maintained or serviced while in operation
unless proper maintenance or service requires the conveyor to be in
motion. In this case, personnel shall be made aware of the hazards
and how the task may be safely accomplished.
K) Owners of conveyor should ensure proper safety labels are afxed
to the conveyor warning of particular hazards involved in operation of
their conveyors.
• Maintenance
• All maintenance, including lubrication and adjustments, shall be
performed only by qualied and trained personnel.
• It is important that a maintenance program be established
to ensure that all conveyor components are maintained in a
condition which does not constitute a hazard to personnel.
• When a conveyor is stopped for maintenance purposes, starting
devices or powered accessories shall be locked or tagged out
in accordance with a formalized procedure designed to protect
all persons or groups involved with the conveyor against an
unexpected start.
• Replace all safety devices and guards before starting equipment
for normal operation.
• Whenever practical, DO NOT lubricate conveyors while they are
in motion. Only trained personnel who are aware of the hazard of
the conveyor in motion shall be allowed to lubricate.
Safety Guards
Maintain all guards and safety devices IN POSITION and IN SAFE
REPAIR.
Safety Labels
In an effort to reduce the possibility of injury to personnel working
around HYTROL conveying equipment, safety labels are placed at
various points on the equipment to alert them of potential hazards.
Please check equipment and note all safety labels. Make certain
your personnel are alerted to and obey these warnings. See Safety
Manual for examples of warning labels.
CAUTION! Because of the many moving parts on the conveyor, all personnel
in the area of the conveyor need to be warned that the conveyor is about to
be started.
REMEMBER Do not remove, reuse or modify material handling equipment
for any purpose other than it’s original intended use.

INSTALLATION
• Conveyor Set-Up
1. Determine primary direction of product
flow. Figure 4A indicates the preferred flow
as related to the drive.
2. Attach supports as show in Figure 4B.
Adjust elevation to required height.
NOTE: If celing hangers are used, see
Ceiling Hangers section.
3. Install electrical controls and wire motor.
•Ceiling Hanger
Installation
If conveyors are to be used in an overhead
application, ceiling hangers may have been
supplied in place of floor supports. Figure
4C shows how a ceiling hanger mounts to
a conveyor section. Ceiling hangers should
be mounted at section joints. For safety
information concerning conveyors mounted
overhead, refer to “Installation Safety Precautions” on Page 3.
• NBEZ Set-Up
1. Mark a chalk line on the floor to locate the center of the conveyor.
2. Place the drive section in position.
3. Place remaining sections on the extended support of the
previous section (Figure 4B and4C).
4. Insure that each bed section is square prior to setting in
place. Refer to Figure 4A. Page 5 for Instructions on How To
Square the Beds. Bed sections must be square in order for the
belt to track properly.
5. Fasten sections together with butt couplings and pivot plates
(Figure 4B and 4C). Hand tighten bolts only at this time.
6. Pull a string taut about 1-2 inches over the top of rollers from
the center of infeed end to center of discharge end of conveyor
to establish a straight line for the conveyor. Measure from string
to every bed joint and adjust as necessary to set the entire
length of conveyor is straight to the string. Use a laser beam
over the entire length to adjust each support to level conveyor.
7. Tighten all butt coupling and support mounting bolts and lag
conveyor to floor.
8. Connect the EZLogic® zone controller cordsets at the sections joints.
9. Mount the IOP (for the EZLogic® System) to the conveyor, near the center. Connect the IOP to the EZLogic® System. See page 7 for more information about these
connections.
NOTE: See the EZLogic® GEN3 Component Manual for more information about the IOP power
connections and for more information about EZLogic® components.

10. For Model NBEZA, connect air lines and
cordsets at section joints as shown in Figure 4F.
11. For Model NBEZA, connect main air supply
line to Filter/Regulator (Figure 4E). Set Regulator
to working pressure of 12 P.S.I.
12. Install and wire any auxiliary cables or I/O
modules. Refer to pages 6 and 7 for more
information about auxiliary connections.
13. Install electrical controls and wire motor. See
page 8.
• Racked Sections
It is important that each bed section be checked
for an out-of-square condition and squared prior
to being set in place. If conveyor is not square,
tracking problems will result. Figure 5A indicates
a racked section.
TO CORRECT AN OUT-OF-SQUARE
SECTION
1. Locate points on corners of section and
measure distance “A” & “B”. If the dimensions
are not equal, the section will need to be
squared. (Figure 5B).
2. Use crossbracing supplied on underside
of conveyor to square each section. Adjust
turnbuckle until Dimensions “A” & “B” are equal.
3. After all bed sections have been checked and corrected for “racked
condition”, tighten all butt couplings and pivot plate bolts.
4. Make final check to see that all conveyor sections are level across width
and length. If entire conveyor is level,
supports can be lagged to floor.
“Racked” conveyor sections will
cause package to travel toward side of
conveyor.
• Belt Installation
INSTALLING THE BELT
The conveyor belt is an endless splice belt that has been sized correctly and
installed at the factory to confirm length. The belt should be installed with the fabric
side down toward the pressure roller carriage and the polyurethane coated side up
toward the tread rollers.
1. Remove tread rollers as necessary to thread belt through conveyor as shown
in Figure 5E.
2. Removal of the snub idler through the access panel and take-up pulley will be
necessary for installation of a new belt.
3. Adjust the belt tension via the 3/8 nut on the end of the center drive box until the
black mark is centered in the belt tension window Figure 5E.
4. Ensure belt is positioned between belt guides through the length of the conveyor.
5. Adjustment of snub idler closest to the infeed end may be required to properly
track the belt.
IMPORTANT: When belt tracking adjustments are made, they should be minor
(1/16 in. at a time on idlers, etc. should be sufficent.) Give the belt adequate time
to react to the adjustments. It may take several complete revolutions around the
conveyor for the belt to begin tracking properly on long, slow conveyor lines.
A) Stand at tail pulley looking toward drive and note what direction belt is
traveling.
B) Having observed belt and determined tracking problem, make minor
adjustments to the snub idlers by moving one side towards the discharge end
as needed. See Figure 5E.
• Belt Tracking
Before attempting to physically track the belt:
1. Make sure all bed sections are square. See information on “Racked
Sections”, Page 5.
2. Make sure conveyor is level
across the width and length
of unit. Adjust supports as
necessary.
3. Make sure all pulleys, return
idlers, and snub idlers are square
with the conveyor bed.
4. Make sure belt has been
properly threaded through
conveyor. See belt installation
above.
5. Tail pulleys can be adjusted for
tracking the belt if needed.
6. Snub roller in drive is to be
adjusted if belt is tracking off
inside drive.
FIGURE 5D
FIGURE 5E
IMPORTANT!
Being out of level across width of conveyor
can cause package drift on long conveyor
lines, and will cause belt to not track
properly. FIGURE 5C
FIGURE 5A
FIGURE 5B

• How to Steer the Belt
Condition 1: When the belt is running in the direction of the belt flow arrow, but
tracking (drifting) towards side “X,” move tail pulley in the angle of the “Y” direction.
Condition 2: When the belt is running in the direction of the belt flow arrow, tracking
(drifting) towards side “Z,” move tail pulley in the angle of the “Y1” direction.
If belt continues to track improperly, re-check all items covered in “Pre-Tracking
Inspection” and make corrections as necessary.
• Electrical Equipment
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).”
OPERATION
• Conveyor Start-Up
Before conveyor is turned on, check for foreign objects that may have been left
inside the conveyor during installation. These objects could cause serious damage
during start-up.
After conveyor has been turned on and is operating, check motors, reducers, and
moving parts to make sure they are working freely.
• Lubrication
Bearings
STANDARD: Supplied, sealed, and pre-lubricated. No lubrication required.
• Sequence of Operation
The Model NBEZ is made up of a series of accumulation zones, each zone
having an EZLogic® zone controller, pressure roller module(s) to apply and
remove drive to tread rollers and brakes at discharge zone. Drive actuation
and/or brake can be either electric or pneumatic based on model chosen.
The EZLogic Accumulation System provides two modes of accumulation
which are user-selectable: Singulation mode and Slug mode. The sequences
of “loading” and “unloading” the conveyor in the two modes are as follows:
LOADING THE CONVEYOR - SINGULATION MODE
1. Beginning with the conveyor empty, and the zone stop signal to the
discharge controller “acive,” a carton placed on the conveyor continues
forward until it reaches the discharge zone (Zone #1).
2. If two or more cartons are placed on the conveyor with a space of less than
one zone length between them, the cartons will singulate (separate) during
the first few feet of travel on the conveyor, until a space approximately equal
to one zone length exists between all cartons.
3. When carton #1 activates controller “A,” Zone #1 stops driving. A signal is
sent to Zone #2 indicating that Zone #1 is occupied (Figure 6A).
4. When carton #2 activates controller “B,” Zone #2 stops driving. A signal is
sent to Zone #3 indicating that Zone #2 is occupied.
5. The above sequences are repeated until the conveyor is fully loaded.
UNLOADING THE CONVEYOR - SINGULATION MODE
1. Releasing carton #1 is accomplished by “de-activating” the zone stop signal
to the discharge zone (Refer to the “Auxiliary Connections” section on pages
6 and 7). This restores power to the tread rollers in Zone #1. Carton
#1 will then move forward, causing a gap between itself and carton
#2 (Figure 6B).
2. When carton #1 clears controller “A,” carton #2 will then move
forward, creating a gap between itself and carton #3.
3. This sequence will continue as long as the preceding carton
continues to move forward.
LOADING THE CONVEYOR - SLUG MODE
1. Beginning with the conveyor “empty,” and the zone stop signal to
the discharge controller “active,” a carton placed on the conveyor
continues forward until it reaches the discharge zone (Zone #1).
2. If two or more cartons are placed on the conveyor witha space
of less than one zone length between them, the cartons will not
singulate (separate) while traveling down the conveyor.
3. When carton #1 activates controller “A,” Zone #1 stops driving. A
signal is sent to Zone #2 indicating that Zone #1 is occupied.
4. When carton #2 activates controller “B,” Zone #2 stops driving. A
signal is sent to Zone #3 indicating that Zone #2 is occupied.
FIGURE 6A
FIGURE 6B
CAUTION! Because of the many moving parts on the conveyor, all personnel in the
area of the conveyor need to be warned that the conveyor is about to be started.
WARNING! Electrical controls shall be installed and wired by a qualied electrician. Wiring
information for the motor and controls are furnished by the equipment manufacturer.

7
5. When carton #2 activates controller “B,” Zone #2 stops driving. A signal is
sent to Zone #3 indicating that Zone #2 is occupied.
6. The above sequences are repeated until the conveyor is fully loaded.
UNLOADING THE CONVEYOR - SLUG MODE
1. Releasing all cartons is accomplished by “de-activating” the zone stop
signal to the discharge zone (Refer to the “Auxiliary Connections” section).
This causes all occupied zones to drive and restores power to the tread
rollers. All cartons then move forward (Figure 6B).
2. All cartons will continue to move forward without singulation as long as the
zone stop signal is de-activated.
MAINTENANCE
• EZLOGIC® CONTROLCONNECTIONS
Each zone controller has a built-in cable to provide a zone drive/no drive
output to the pressure roller module(s) for each zone. This cable is terminated
with a female Pico-style sealed snap-lock connector. Connection is made by
pushing the cable connector onto a connector tee cable. This connector fits into the
connector on the drive module. If there are more than one pressure roller modules
in a zone, an additional tee cable can be connected in series with the initial cable
to control the additional modules. When the drive board receives a “run” signal from
the EZLogic® zone controller, the drive module is actuated to apply force to the belt
to drive the tread rollers in a zone.
When the GEN3 NBEZ controller is used, power to the drive module and brake
are supplied through the controller. This only applies to the GEN3 NBEZ controller
shown in Figure 7B.
• Please note that this output is only to be used to operate the zone mechanism
of the conveyor. It is not to be used as an output signal to other control
devises. If a control output is needed, an optional auxiliary I/O module should
be used. Please refer to the EZLogic® GEN3 Component Manual for more
information.
AUXILIARY CONNECTIONS
Every EZLogic® zone controller is equipped with an auxiliary port to accept
a zone stop signal, a slug input signal, or a zone wake-up signal by simply
connecting an auxiliary input cable to the auxiliary port of the controller and
then wiring the two wires of the cable to any “dry contact” type switching
device, such as a toggle switch or relay. No other components are required.
The default setting is for a zone stop signal. To use the signal for slug input
or zone wake-up, program the zone controller as detailed in the EZLogic®
GEN3 Component Manual.
NOTE: Do not apply a voltage to these wires, or wire more than one controller
to any one contact.
SLUG MODE CONNECTIONS
The EZLogic® accumulation system provides two modes of accumulation
which are user-selectable: Singulation mode and Slug mode. (For descriptions
of the sequence of operation for each mode, refer to the “Sequence of
Operation” section on pages #5 and #6. The desired mode of operation may
be programmed into the zone controllers at installation (refer to the EZLogic®
GEN3 Component Manual for details). If the user wishes to be able to
alternate between singulation mode and slug mode “on-the-fly,” an optional
Auxiliary Input Cable (Hytrol P/N 032.563) may be used. The default mode is
singulation mode. If the user desires to operate the conveyor in slug mode, or
if the user wishes to be able to alternate between the two modes as needed,
the following procedures should be used.
SLUG MODE ONLY
Program the zone controllers to operate in “slug mode only” as detailed in the
EZLogic® GEN3 Component Manual.
SELECTABLE SINGULATION/SLUG
1. Install an auxiliary input cable (Hytrol P/N 032.563) on any zone controller
of the conveyor. The cable attaches to the auxiliary port on the conroller (see
Figure 7A).
2. Program the zone controller to accept a slug signal. (Refer to the EZLogic®
GEN3 Component Manual for details.)
3. Connect the two wires of the Auxiliary Input Cable to any “dry contact” type
switching device, such as a toggle switch or relay.
4. With the switch contacts open, the conveyor will be in singulation mode.
When the switch is closed, the conveyor is in slug mode.
NOTE: Do not apply a voltage to these wires, or wire more than one
controller to any one contact.
• IOP Unit (Power Supply for GEN3
EZLogic®)
The model is equipped with an IOP unit (power supply). The IOP unit provides DC power for the
EZLogic® system and provides a wiring hub for advanced features (if I/O boards are present).
The IOP unit connects to the EZLogic® system by way of an IOP Tee Cable mounted in line
with the zone controller cordsets (see Figure 8B).
NOTE: See EZLogic® GEN3 Component Manual and IOP Solutions
Manual for more information.
• NBEZ Specifications
Using the specific EZLogic® controllers for NBEZ (032.5017), connect the solenoid output
cable on the EZLogic® controller to the Dual Actuator Adapter Module (Figure 8C).
The remaining legs of the tee are connected to the M8 connector from the drive module. If
you have more than two drive modules in a zone, an additional Dual Actuator Adapter Module
is required.
To connect the brake, a Braket Adapter Module is connected to the auxiliary port on the
EZLogic® controller, an extension cable is then required to connect the brake cable to the
brake via the M8 connector extended from the brake module. To connect two brakes in series
from one EZLogic® zone controller, the Dual Actuator Adapter Module will be needed to
connect the brakes. CAUTION: NO MORE THAN A COMBINATION OF FIVE
(5) TOTAL DRIVE AND BRAKE MODULES CAN BE CONNECTED TO ONE
ZONE. No additional power supply is required when using the NBEZ GEN3
controller. Power to the drive and brake modules come from the IOP. The IOP
is limited to ten 24-inch zones or eight 36-inch zones. In order to provide
I/O at the discharge of the NBEZ, an additional EZLogic zone controller is needed
with an auxiliary I/O module (032.532) and mounted to provide a zone stop or other
communication to a PLC. Figure 8E.
• NBEZA SPECIFICATIONS
The operation of the NBEZA is like the NBEZ apart from using pneumatics
for the drive and braking activities. To provide drive to the unit, connect the
solenoid output cable of the EZLogic® zone controller to the solenoid air valve
operating the zone. Connection is made by pushing the cable connector onto
the corresponding male connector of the valve until it snaps in.
The valve used when operating the drive and brake is different from the valve used
to operate the drive only. The valve on the very discharge for operating the drive and
brake is a 4-way single solenoid whereas the valve in the remaining zones is a 3-way
solenoid valve.
If there are multiple drive modules in a single zone, there is one that has a single port
air bag where subsequent modules have double port air bags to control the drive in
one zone.
• NBLR SPECIFICATIONS
The Model NBLR is equipped with fixed drive roller modules spaced every 12 inches
along one side of the conveyor to apply the driving force between the belt and tread
rollers.

• EZLOGIC® ZONE CONTROLLER
DEFAULT SETTINGS
The zone controllers will be set for the default settings when the unit leaves
the factory. However, if you need to replace a zone controller, the new zone
controller will need to have parameters changed so that the zone will operate
properly.
To make the changes, you will need the EZLogic® OS configuration
software installed on a PC and a USB programming cable. Connect the USB
programming cable to a USB port on the PC and the other end to the auxiliary
port on the zone controller. Make sure the zone controller is powered by the
IOP or from another 24-27VDC power source. Start EZLogic® OS by double-
clicking its icon on your desktop. When the software opens, navigate to the
File menu. From the Load from Defaults submenu, select the E24EZ as the
default configuration, click SAVE, click OK. Next, select the Configuration from
the main menu options. Make the following changes to the parameters:
• Singulate/Slug – change to Slug Only – Click SAVE
• Special Logic Function – select High-Speed Accumulation
o Click NEXT (Select the default timer setting. This can be changed later if
necessary.)
o Click SAVE
Your new zone controller is now programmed for default NBEZ/NBEZA
settings. The EZLogic® OS configuration screen should look like this:

• NBEZ TROUBLE SHOOTING
The following chart list possible problems that may occur in the operation of
an NBEZ conveyor.
*NOTE: The standard application of this model does not have brakes in every
zone. Therefore, zero-pressure accumulation will not necessarily be obtained.
Products will drift into downstream zones when drive is removed from a zone.
TROUBLE CAUSE SOLUTION
Conveyor will not start or motor
quits frequently
