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.

motor and can be stopped only by turning off
electrical power to the motor. As with all
powered machinery, the drive-related
components – including sprockets, chains,
shafts, universal joints, and pneumatic devices
– can be dangerous. We have installed or
provided guards to prevent accidental contact
with these parts, along with warning labels to
identify the hazards.
Special attention must be paid to the following
areas of this manual:
•Indicates a potentially hazardous
situation, which, if not avoided,
could result in death or serious
injury.
•Indicates a situation, which, if not avoided, could
result in property damage.

will be replaced by TGW Systems at no cost by contacting Lifetime Services.
•It is very important to instruct personnel in proper conveyor use including the location
and function of all controls.
•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.

3.4: 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 the entire 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®90 PolySort & SP IOM
P/N: 1193974 Revision Date: 4/25/2019 Page 13 of 83
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®90 POLYSORT APPLICATION GUIDELINES
NBS90 PolySort Selection
Due to the high degree of polybag variance and physical characteristics of typical contents (e.g. pliable,
irregular, light, loose, etc…) it is vital for the Systems Integrator to fully understand the physical
parameters of all conveying products and how well it should perform for the full product range expected
to convey. It remains the responsibility of the Systems Integrator to ensure that the equipment
proposed is capable of handling the products in the manner desired.
The Polysort unit is designed specifically with polybag handling in mind, as shown by the
following features:
•Transfer Tubs have extra high lift and drop above/below the conveying surface by 1/2” to allow
for loosely packed polybags.
•Belts and Divert Rollers are on tighter 2-1/2” centers to help support pliable or irregular
products
•High friction Divert Rollers stop and convey polybags quickly “on the fly”
oNote for Carton Handling:
The high friction surface can cause higher center of gravity products to tip at
high speeds and rates. Generally, products convey well if the center of gravity
is no more than 25% of product width or height. Consult with Applications
Engineering for your specific application.
•Transfer Tubs use high performance SEW Movimot drive motors for quick response and high
efficiency
•Bed Rail connections and infeed points are rounded and scalloped to reduce product snagging
•Divert Tubs are fitted with infeed ramps between each lane to minimize snagging and
maximize rate
•Small Array Photo Eyes are used to sense products 5mm thick
Given the above design features, the nature of conveying products with irregular or loose conveying
surfaces are not guaranteed. TGW has tested a wide range of products contained in polybags with
successful convey with the vast majority of “normal” industry packaged polybags from companies in the
Apparel, Postal/Parcel, and Distribution markets.
Consult with TGW Applications Engineering for your specific needs or to arrange product
testing.
•Post sort orientation may not be maintained. Typical divert is onto a
chute, bin, tub or similar. Consult with TGW Applications Engineering for
specific details or to arrange product testing.

P/N: 1193974 Revision Date: 4/25/2019 Page 18 of 83
Use NBS90 PolySort when:
•Tighter belt centers than our standard NBS is required
•Product may be same size and weight, or mixed
•Product weight: less than 2oz. – 40 lbs. Max, 1,000 lbs. total live load
•Products typically convey onto chute or dump into tote, Gaylord, or similar
•Ambient temperature is +35° to 100°F
NBS90 PolySort Application Notes:
•Matching conveyor rates before and after NBS sortation are vital to proper application decisions.
•If orientation integrity is required post transfer, products would need to be tested.
•The transfer exit lanes from NBS90 PolySort can be gravity roller (used as a deceleration area),
chutes or powered conveyor run at a speed which allows the lane to receive products as fast as
they are transferred.
•The maximum divert rate for a NBS90 PolySort single-direction is 50 CPM. The bidirectional
rate is 50 CPM. (Contact the Customer Support group for application consideration above
these rates)
•Induction to NBS90 PolySort sortation must be able to singulate individual products. Minimum
induction gap varies with line speed and determine product pitch.
oSpeed / Pitch = Rate. Reference chart example below.
PolySort Rate w/Max Polybag
Speed (FPM) Min Gap

300 44 28 72 50
High rates are possible given ideal product size and type, edge aligned and induction control upstream
of PolySort, and programming optimization. Consult with TGW Applications Engineering for
specific details or to arrange product testing.
•To increase rate justify all products along the exit lane side of the NBS90 PolySort sortation for
single direction transfer.
•When NBS90 PolySort over-all-length is over 50' and up to 100' in length, an addition auxiliary
air take-up is required.
•The maximum length of a NBS90 PolySort sortation conveyor, including two air take-up units, is
100'.
•The use of a VFD (Variable Frequency Drive) or at least a "soft start" motor drive is
recommended for NBS90 PolySort drive motor control. Ignoring this point may void the motor
warranty.
•The use of a VFD (Variable Frequency Drive) is required for NBS drive motor control. Ignoring
this point will void the belt motor manufacturer’s warranty.

NBS90 PolySort Elevation Top of Belt
The minimum elevation at the discharge end of an NBS90 PolySort sortation line is 19". The end drive
unit is located at the discharge end and requires a space of 60" or 33” long.
Extra room alongside the drive should be provided to allow maintenance personnel access to either
side of the drive assembly. In order to remove air take-up from bottom side of conveyor, add 6” of
clearance and 7” for transfers.
NBS90 PolySort Transfer Locations
•The leading edge of the first transfer module must be a minimum of 11 1/8" from the charge end
of the sorter.
•The trailing edge of the last divert module must be at least 11 1/8" from the discharge end.
•The center line of a transfer exit lane is centered on the center line of the transfer rollers in an
NBS90 PolySort.
•Standard available coated transfer rollers widths are: 25 1/2"
•One NBS90 PolySort transfer can transfer to up to four separate lanes of 1/2 the width of the
roller length.
•Single direction transfer to two lanes is called a "Dual Transfer"
•Bi-directional transfer to two lanes each side is called a "Quad Transfer"
