Rev 03/01/2019
TGW Environment Standards
TGW equipment is designed to be installed in a clean,
dry warehouse environment. Exposure to extreme
humidly, direct sunlight, blowing dirt or rain can
permanently damage some components of TGW
conveyor. In particular, the curing agents in concrete
are known to attack and degrade the urethane
conveyor components.
When installing conveyor on a new construction site,
be sure that the concrete is properly cured before
setting conveyor on it. In addition, if conveyors are
stored in the proximity of curing concrete, proper
ventilation must be used to direct the curing agent
fumes away from the conveyor.
Failure to comply with these guidelines will void the
TGW warranty on any failed components that result
from these environment issues.

•Special emphasis must be given to emergency stop procedures.
•It is important to establish work procedures and access areas, which do not require
any part of a person to be under the conveyor.
•It should be required that long hair is covered by caps or hairnets.
•Loose clothing, long hair, and jewelry must be kept away from moving equipment.
•Maintain enough clearance on each side of all conveyor units for safe adjustment and
maintenance of all components.
•Provide crossovers or gates at sufficient intervals where needed to eliminate the
temptation for personnel to climb over or under any conveyor.
•Walking or riding on a moving conveyor must be prohibited.
•Before performing maintenance on the conveyor, make sure the start-up controls are
locked out and cannot be turned on by any person other than the one performing the
maintenance.
•If more than, one crewmember is working on the conveyor, EACH CREW MEMBER
MUST HAVE A LOCK ON THE POWER LOCKOUT.
•All pneumatic devices must be de-energized and air removed to prevent accidental
cycling of the device while performing general maintenance.
•Make sure all personnel are clear of all conveyor equipment before restarting the
system.
•Before restarting a conveyor which has been stopped because of an emergency, an
inspection of the conveyor must be made and the cause of the stoppage determined.
The starting device must be locked out before any attempt is made to correct the
cause of stoppage.

3.5: TGW SYSTEMS CONVEYOR CONTROLS SAFETY GUIDELINES
The following basic conveyor control safety guidelines are recommended by TGW Systems even
though Business Partner may or may not purchase conveyor controls from TGW Systems. The items
listed deal with applications of controls equipment. The actual installation of the equipment must
always follow the National Electric Code and all other local codes.
Start-up Warning Horn
Ideally, all conveyors should be within sight of the conveyor start pushbutton. This allows the operator
to verify that no one is touching the conveyor or would be in danger if the conveyor were to start up.
If it is not possible to see all of the conveyor being started from the start pushbutton location, then
some form of audible warning device is required. It could be a horn, buzzer, bell, or anything unique to
that conveyor for that location. It should be loud enough to be heard at any point on the conveyor
system. It should sound for approximately five seconds after the start pushbutton is pushed, prior to
the actual running of conveyor. Any auxiliary equipment such as vertical lifts, turntables, etc., should
also be included in the warning circuitry.
Conveyors that stop and restart under automatic control could also require a horn warning prior to
restarting. If it is not easy to distinguish the difference between a fully stopped conveyor system and a
momentarily stopped conveyor section, then it is advisable to add a warning horn. All conveyor
sections that stop and restart automatically should be marked with appropriate signs or labels.
Start Pushbuttons
Start pushbuttons should be the flush type or guarded such that inadvertently leaning against them
will not actuate the conveyor. They should be provided with a legend plate clearly defining which
conveyors will be started.
Stop Pushbuttons
Stop pushbuttons should be the extended type such that any contact with it is sufficient to stop the
conveyor. They would also be provided with a legend plate clearly defining which conveyors will be
stopped.
Operator Controls
Additional operator controls should be designed into the system with the same guidelines that go into
start and stop pushbuttons, depending upon their function. Devices which are repeated on multiple
control stations, such as emergency stops, should be located at the same relative location on each
station (such as lower right corner).
Emergency Stops
All locations where an operator must work directly at the conveyor should be protected by an
emergency stop. An operator should not have to move from where he is to actuate the emergency
stop.
Conveyors in areas of high pedestrian traffic should also be protected by emergency stop devices.
For all other instances, emergency stops should be located throughout a system such that it is
possible to shut down the system without having to walk too far. In these instances the emergency
stop is used more to protect the equipment from damage than to protect personnel.
Emergency stops can be of the pushbutton or cable operated switch type. The pushbutton type
should be a red, mushroom head maintained pushbutton which requires resetting after it is actuated.
Cable operated switches should trip by pulling the cable, and require resetting at the switch.

NBS®-BR IOM
P/N: 1116149 Rev: 03/14/2019 Page 13 of 110
Actuating an emergency stop must drop-out the start circuit, requiring restarting the system using the
start pushbuttons provided.
An emergency stop should normally stop all conveyors in the system. Very large systems may involve
dividing a system into zones of control based on proximity of personnel, safety hazards, walls
obstacles, etc.
Controls Logic
Solid state controls logic devices, such as programmable controllers are used extensively for
conveyor control. They are very reliable, but a hardware failure or software bug would cause an
output to function erratically. For this reason, start circuits, warning horn circuits, and emergency
stops should usually be configured using conventional relay logic.
Safety Switches
All conveyor control cabinets and motors should be provided with safety (or disconnect) switches.
These switches must have provisions for padlocking. As required for maintenance, equipment should
be locked in the off position.
Special Devices
Special devices and equipment such as vertical lifts, turntables, high speed conveyors, etc., all have
unique design and safety requirements. These should be looked at in each case to determine what
the requirements might be.

Chapter 4: NBS INTRODUCTION
NBS Concept
The TGW Systems NBS Narrow Belt Sorter technology was developed to provide an economic
alternative to other sortation devices, as well as providing sorting options that were not easily
available.
This technology is similar to sorters that use wide flat load carrying belts and pop-up wheels to divert
product but has eliminated many of the high cost / maintenance features associated with these
sorters.
Limitations on availability of bi-directional diverts, long divert lane center-line distances, as well as the
high costs associated with the skilled labor required to install these wide belts have been addressed
with this technology.
Features and Benefits
Features and benefits common to the NBS 30, NBS 90 low friction rail technologies include:
•Product is continuously carried on multiple narrow belts for smooth bump-free conveying and
excellent tracking accuracy.
•Narrow belts slide on low friction roller bearing guides, resulting in reduced noise and virtually
eliminating tracking problems.
•Multiple narrow belts are progressively guided through the sorter to minimize belt tracking
issues
•Narrow belts run flat and straight through NBS modules without snubbing or back-wrapping
resulting in reduced horsepower requirements.
•Simple user-friendly design allows ease of installation and maintenance.
•Compact modular design of modules allows closer divert/transfer lane center distances.
•Modularity and universal mounting of modules allows easy repositioning or reconfiguration in
the field.
•Gravity take-away or spurs may be used in many applications to lower initial costs.
•NBS technology costs less than conventional full width belt sorters in material as well as
installation costs.

Chapter 5: NBS RECEIVING AND SITE PREPARATION
Receiving
TGW Systems NBS Narrow Belt Sorters are shipped in subassemblies. These subassemblies are
packaged to guard against damage in shipment, when handled properly.
Examination immediately following unloading will show if any damage was caused during shipment. If
damage is evident, claims for recovery of expenses to repair damage or replace components must be
made against the carrier immediately. While unloading, a check must be made against the Bill of
Lading, or other packing lists provided, to confirm full receipt of listed items.
•TAKE CAUTION DURING THE REMOVAL OF EQUIPMENT FROM THE CARRIER.
Remove small items and boxes first. Pull and lift only on the skid, not on the frame, cross
member or any part of the conveyor equipment.
Preparation of Site
After the conveyor is received, move it to the installation, or designated dry storage, area as soon as
possible. Clean up all packing material immediately before parts get lost in it. Loose parts should
remain in the shipping boxes until needed.
Prior to starting the assembly of the conveyor, carefully check the installation path to be sure there are
no obstructions that will cause interference. Check for access along the path needed to bring in bed
sections and components closest to the point where they are needed. It is often necessary to give the
area, along the system path, a general cleanup to improve installation efficiency, access, and
accuracy.
