2 OSHA and Safety
Bastian Solutions Conveyor is not responsible for ensuring that conveyors used in a system abide by
OSHA standards. Safety is of primary importance to our company, but as a product distributor we ask that
system integrators and end users conform with all applicable OSHA standards. We encourage that all
warnings in this manual are followed to avoid unnecessary risk.

3 Model: RZPAC
3.1 Overview
The Roller Zero Pressure AC (RZPAC) conveyor is designed for longer runs of zero pressure
accumulation, especially in applications where a combination of high speed and heavy product make DC
accumulation conveyor impractical. RZPAC uses a continuous belt under the conveying rollers driven by
an AC gearmotor motor, which is engaged and disengaged with the various conveying zones with
pneumatic actuators. Pneumatically driven brakes are used to stop the zones when the belt is
disengaged. A system of low voltage DC photoeyes and control cards senses product location and uses
solenoid valves to control the zones in any of several zero pressure control modes.
Figure 1: RZPAC Overview
3.2 Belt
The main conveying belt is 99mm wide and is available with two different joining options.
The laced belt is quick to install and quick to repair, and does not require special tools or expertise with
the lacing factory installed. It is well suited for any conveyors within its load capacity (light to medium
product loads, or heavy loads on shorter conveyors).
The hot-spliced belt requires special tools and skills to create splices, and cannot be installed or replaced
as rapidly due to the minimum time required for the splices to heat and cool. However, it is a more
durable option that is necessary for very heavy loads (working strength of the hot splice is about 2.7 times
the working strength of the lacing) and is maintenance-free for the life of the belt. The hot-spliced belt is
also quieter because there is no metal lacing contacting the conveying rollers.

3.3 Drive Section
Two different drive designs are available for RZPAC conveyors. The screw (fixed) takeup drive is the
least expensive option and is available for conveyor lengths up to 100 ft and total product loads up to
1050 lbs with a laced belt or 3200 lbs with a hot-spliced belt. Because the screw takeup drive is manually
tensioned, it requires periodic tension adjustment as the belt elongates. See Table 6: Recommended
Preventative Maintenance Schedule in section 6.2 for the required belt retensioning frequency.
The pneumatic takeup drive offers a low-maintenance automatic tension adjustment and a longer belt
takeup distance for conveyor lengths up to 200 ft, or heavily-loaded conveyors. Since the pneumatic
takeup automatically adjusts belt tension based on the conveyor load, it can handle heavier total product
loads, up to 1900 lbs with a laced belt or 4100 lbs with a hot-spliced belt.

Figure 3: Pneumatic Takeup Drive Overview
3.4 Tails
The RZPAC tail section is a 36” conveyor section that contains the tail pulley and a snub roller. The tail
sections are always placed as the first and last bed sections in an AC mark number. Rollers in the tail
section are banded together to transmit power from the zero pressure zone in the section to the rollers
above the tail pulley.
Optional power takeoff (PTO) timing pulleys may also be installed on a tail section, to drive an additional
conveyor section from the belt of the RZPAC conveyor.
Due to the nature of a PTO driven conveyor section, the driven conveyor cannot be
shut down without stopping the belt of the RZPAC conveyor, which will prevent
products on the RZPAC from advancing. Special attention is required to the system-
level control logic if a conveyor is to be driven from the infeed of an RZPAC conveyor. If
the RZPAC conveyor zones fill with product, any additional product entering the infeed

driven conveyor will cause a jam and shutdown of both the RZPAC and the infeed
driven conveyor that cannot be cleared without manually unloading the product.
3.5 Intermediate Beds
Intermediate beds contain one or more zero pressure zones and modules. An intermediate bed consists
of conveying rollers on the top, with pressure rollers mounted in modules below. The belt will be routed
between the conveying rollers and the pressure rollers during installation. One sideframe of the bed will
also contain all the cards, solenoids, and photoeyes, as well as the air and 24V DC electrical connections
that get installed along the full length of the conveyor. The brake modules will also be mounted on the
inside of this same sideframe. See Figure 4: RZPAC Intermediate Bed Exploded View for details.

4 Receiving
Upon delivery of any Bastian Solutions conveyor, please review and check the following:
•The quantity of items received against the Bill of Lading.
•Complete a visual inspection of equipment to determine any damage that may have occurred
during shipping. If damage is present, document with pictures.
•Review Mark Number information and layout locations. More information can be found in
subsection 4.1.
If there are any missing or damaged components contact your Bastian Solutions Conveyor representative
with as much detail as possible. If you are unsure of your Bastian Solutions Conveyor representative,
please contact Customer Service at ConveyorSupport@BastianSolutions.com.
4.1 Mark Numbers
A mark number is a specific number given to a piece of equipment. A mark number is usually made up of
a single product line (RZPDC, RLVDC, BZPDC, etc.) but can contain many bed section lengths. They can
range from two inches to hundreds of feet. The mark number is used to help identify where the piece of
equipment will go within the system layout.
Every bed section of conveyor will have (2) stickers. One sticker on the infeed end of the bed, and one
sticker on the discharge end of the bed. Each sticker will contain the following information:
•BSC Project Number and Name
•Model Type
•Mark Number
•Match
•Piece
•Flow
Figure 5 shows stickers that would appear on an RZPDC that has two bed sections.
The match field on the stickers is used to indicate if two bed sections are to be spliced to one another. As
shown in Figure 5, the stickers where the two beds splice together both contain “Match: 1”. The piece
field defines the bed section number within the mark. The flow refers to the direction of product flow along
the conveyor system.
4.2 Skid Contents
Skids will contain varying combinations of conveyor sections, support structures, accessories, and
pertinent hardware. For protection of product integrity during shipping, accessories and supports may be
delivered on separate but labeled skids.
4.3 Skid Documentation
All shipments will contain a Bill of Lading for the delivery company, a skid label, and a skid manifest. Skid
labels have the contents of each shipped item located on the skid. Figure 6 shows a sample of a skid
label. These stickers are placed on the surface of each skid.
Figure 5: Mark Number Stickers

RZPAC conveyor may arrive in multiple skids for the same mark number. The number of skids shipped is
dependent on the OAW and OAL of the mark number.
Upon receiving the skid on site, please inspect for any visual damage of the equipment. If there are any
damages, please contact your BSC representative with images and details of the skid.

5 Installation
5.1 Layout
The installation supervisor on site should have the elevation and layout prints with detailed information
regarding the placement of conveyor sections and support structures. This information is not the
responsibility of Bastian Solutions Conveyor to provide unless otherwise specified.
1. Clear the workspace around the portion of the layout selected for installation.
2. Ensure that the conveyor and accessory skids containing the correct RZPAC mark number are
unpacked and all components are accounted for.
3. Measure out from the constrained origin to start placement of supports. It is recommended that
snap chalk lines are used, or other methods of keeping a consistent line.
A straight and level installation is crucial to proper belt tracking. The extra time spent
creating an accurate layout will more than pay for itself in time saved during belt
tracking and troubleshooting.
4. Use the elevation layouts to determine the top of conveyor surface and the incline/decline angle
of a mark section.
5. Place the support type that the layout designates.
6. Check the approximate height of each support and adjust if necessary. Final heights will be set
after the supports and conveyor are installed.
5.2 Setting the Conveyor
1. Check the flow direction on the mark stickers to ensure that conveyor is installed in the correct
order and that each section is facing the correct direction.
2. Starting from one end, place the conveyor onto the support structure and fasten with 3/8”-16
carriage bolts and serrated flange nuts.
3. Install a splice plate underneath each top flange at the bed break with 5/16”-18 hex bolts and
serrated flange nuts. Use the splice plate to align the mating sideframes vertically and
horizontally. See Figure 7: Floor Support and Splice Plate Installation.
4. Before moving on to the next section, torque the 5/16” splice plate fasteners to 17 ft-lb and the
3/8” floor support fasteners to 31 ft-lb.
Do not lift the drive section of the conveyor using the lifting lug on the AC motor and
gearbox. This will cause damage to the gearbox and drive pulley.
5. Check that the upstream and downstream heights of the conveyor section agree with the system
layout instructions and that the conveyor is leveled side-to-side.
6. Check that all floor supports are aligned with the chalk line or other layout mark to ensure that the
conveyor is straight.
7. Secure the supports to the floor (or other permanent fixture).

1. Starting at one end, use a laser level or other accurate method to check the sideframe height at
each bed break on both sides of the conveyor, and adjust the supports as needed. All bed breaks
should be in the same plane and level side-to-side, +/- 1/16”.
2. Run a string line along the centerline of the conveyor, down its entire length, approximately 2”
above the rollers. Tension the string until it is freely suspended (not touching any rollers).
3. Measure the distance between the string and the edge of the sideframe at each bed break. The
distance should be the same at every bed break, +/- 1/8”. Adjust by loosening the support
anchoring bolts and sliding the entire floor support sideways if needed. The floor support
anchoring holes are slotted to allow some side-to-side adjustment. Re-secure the support once it
is in position.
5.4 Installing the Belt
1. Remove a few idler rollers near each tail, and approximately every 50 feet along the length of the
conveyor, as needed to pull the belt through. See section 6.7.4 for details.
2. Mount the roll of belting on a sturdy pole or axle, secured between the tines of a forklift or similar,
where the belting can be easily unrolled. Position the belt behind the tail of the conveyor nearest
the drive.

The belt should be installed with the shiny traction layer facing up towards the
conveying rollers and the textured or fabric side down towards the pressure rollers. For
belts with traction material on one side only, this orientation is important for correct
functionality. For belts with traction material on both sides, keeping the shiny layer
towards the conveying rollers will reduce noise.
3. Tape a thin piece of metal or stiff cardboard to the end of the belt to keep the end straight and
help guide it through the conveyor. Make sure the final thickness is less than 1/4”.
If the belt is prepared for a hot splice joint, it will have a small scrap of belting taped to
the end to protect the finger joint. Leave that piece of belting in place.
4. Once the belt reaches the other end of the conveyor, route it through the tail and pull the belt
through, leaving the return span hanging below the conveyor.
a. See Figure 8: Tail Belt Routing for belt routing through the tail.
b. Ensure that the return span of the belt is routed above any items (floor support cross
braces, conduits, etc.) that might cross underneath the conveyor.
5. Once the end of the belt reaches the drive, pull additional belt through until the roll is empty.
Position the end of the belt on the top of the conveyor in a convenient place to join the belt ends.
6. Route the belt through the drive. See sections 5.11.1 or 19 for belt routing, depending on whether
the conveyor uses a screw takeup or pneumatic takeup drive.
7. Route the belt through the second tail and bring the two belt ends together.
8. Remove tape from the belt.
9. See section 5.4.3 if the belt uses a hot spliced joint.
Figure 8: Tail Belt Routing
10. If the belt uses a laced joint, both ends should ship from the factory prepared with lacing.
a. Bring the two ends together and insert the lacing pin.
b. Trim the lacing pin approximately ½” to 1” longer than the belt on both sides.
c. Fold the end of the pin over and tuck it into the lacing on the upstream side of the belt.
Note that the belt moves opposite of product flow, so the upstream side of the belt is
