Model 2080-03 and 2080-13 Scanners Installation and Maintenance Introduction
1. Introduction
Tasks such as sensor calibration, control tuning, and operator training are not
included in this manual. For information on those areas, refer to the
documentation that shipped with the sensor and the computer control equipment.
If you are planning to install the Model 2080-03 and 2080-13 Scanners for the
first time, it is recommended that you contact Honeywell-Measurex regarding the
availability of training in your area. To avoid violating regulatory restrictions on
the installation and testing of Honeywell-Measurex sensors containing radioactive
sources, you should carefully review and comply with the requirements
summarized in Appendix B, “Radiation Licensing Requirements.”
Note:
In addition to the documents listed above, refer
to the Production Release and Bill Of Materials
for your system.
Chapter 1, Introduction, provides the purpose and scope of the manual, the
intended audience, related reading material, and a list of conventions used
throughout the document.
Chapter 3, Preparing the Site, details the grounding and power specifications,
the environmental and utility requirements, and the cable and conduit
specifications required to install the scanners.
1.5. Conventions
The following conventions are used in this manual:
Courier New 10 pt User commands and typed entries are shown in this
or 11 pt Bold special type.
Times New Roman In text, boldface is used for key terms, button
12 pt Bold names, menu and screen selections, and emphasis.
The Model 2080-03 and 2080-13 Scanners (09208003 and 09208013) are
compact, precision scanners that support Honeywell-Measurex online thickness
sensors in a variety of industrial applications, such as flat die extrusion and vinyl
calender.
The following sections provide an overview of the Model 2080-03 and 2080-13
Scanners, related system components, and the installation procedure:
• Scanner Features
• Installation Overview
This procedure does not include calibrating the sensor(s), control tuning, or
installing other system components, such as the host computer (or its software).
Refer to the manuals provided with your system for information about these
components and procedures.
Before installing Model 2080-03 and 2080-13 Scanners, you must determine
where the hardware components will be placed and then prepare the site. The
site preparation includes:
• Mounting bolts
Use the installation diagrams in Chapter 5, “Installing the Scanners,” to help you
determine the physical dimensions and requirements for your scanner installation.
In addition, the following sections of this chapter define the scanner installation
specifications:
• Power Requirements
• Cable Requirements
Use the Scanner Installation Checklist to guide you through the site preparation.
All grounding must comply with the U.S. National Electrical Code (NEC) and
local electrical codes.
• The enclosure around the scanner must have a low impedance path to
the third wire (green) safety ground.
• The distance from the scanner to a proper ground cannot exceed 100 feet
(30.5m).
• When cable trays are used, use only cables that have been approved
for this use.
• If it is more convenient, you may use the same conduit or cable tray
for both signal cables and DC power cables.
• Extend all cables beyond the conduit or cable tray ends a minimum of
12 feet (3.7m) for terminations.
Recommended conduit-type cables are listed in Table 3-1. The cable numbers
correspond to the numbers on the installation drawings in Chapter 5, “Installing
the Scanners.”

2. Calculate the sum of the individual cross-sectional areas of all the cables
in the run.
3. Determine the conduit size. For example, for a system configured to use
cables numbered 1, 2, 3, 4, and 6, the sum of cable cross-sectional areas
is 0.65 in2 (4.2 cm2). Therefore, a conduit with a diameter of at least
1.5 inches must be used to meet the “40% full” requirement of the NEC
specification.
Table 3-1 lists the cables approved for use in conduits (not for cable trays). You
can use this information to obtain the cable locally, if necessary, and to assist in
calculating the size of the conduit needed for the cable runs.
• Use rigid metal conduit on all signal runs. Where races are exposed to the
weather, at wet locations, or where the conduit is embedded in concrete,
use galvanized steel conduit. The steel conduit forms an electromagnetic
shield around the signal cables. Using conduit made of an alternative
material degrades the shielding effect.
• Ensure that any bends in rigid conduit do not damage the conduit wall or
reduce the internal diameter. A run of conduit from outlet to outlet, from
fitting to fitting, or between outlet and fitting should have less than the
equivalent of 4 one-quarter bends (360° total), including those bends
located immediately at the outlet or fitting.
• Use insulated bushings at the conduit exits to protect wires from abrasion.
• Use pull boxes or oversized elbows below stations and at major junctions
to ease cable pulling and to minimize the risk of cable damage.
• Use NEC-specified pull boxes that provide enough free space for all
conductors in the box.
• Use one of the following types of tray systems (in decreasing order of
preference):
− Open ducting
− Ventilated trough
− Solid tray
• Use materials and installation procedures that meet NEC Article 318
specifications (or the local equivalent in foreign countries).
• Protect the cable tray system from mechanical damage and abrasion.
• Cables must be suitable for cable tray systems, and they must meet the
requirements of NEC Article 725 for Class 2 and Class 3 circuits. Refer
to Table 3-2 for the Belden-equivalent cable for use in cable trays.
Belden 9333 11 pair, 22 AWG, individual, PVC 0.551" (1.40 cm) 0.016" (0.406 mm) insulation
0.053" (1.35 mm) jacket
Belden 9328 1C, 6 AWG, Green, PVC (ground) 0.316" (8.026 cm) 0.070" (1.778 mm)
• If the existing wiring at your site does not produce radiated electrical
interference, either continuously or of a pulsed nature (such as master time
clock system wiring), you can run Honeywell-Measurex cables in the same
tray system as existing wiring.
The scanner requires plumbing for potable water and instrument air that is dirt-
and oil-free. Figure 3-1 shows the environmental and plumbing requirements for
a typical scanner installation. Additional specifications (for example, added
airflow) may be described in the Production Release for each particular scanner.
Note:
Some sensors require a water source that is temperature-
stabilized to ±1.5°F (±0.8°C). The use of an external
water chiller for the factory water supply is recommended.
Cooling water should be of potable quality for cleanliness
and pH. See the specific sensor manual for exact
temperature specifications.
Requirement Specification
Water Cooling Sensors on the scanner are often water-cooled. Cooling water should not exceed
72°F ±1.5°F, max.; 0.5 GPM/sensor; potable.
Air Basis Weight Sensors on the scanner are driven by static air pressure and use
continuously flowing air for the air curtain. Plumbing for instrument air (clean, dry,
oil-free) should be 60 psi for the sensor at the head, and 4 to 6 CFM at 30 to 50 psi
for the air curtain at the head.
This chapter describes the procedures you must perform when a Model 2080-03
or 2080-13 Scanner arrives on-site. The procedures include:
2. Inspect the shipment for damage before unpacking the hardware. If the
shipment shows evidence of damage, follow this procedure:
WARNING:
Do not move or handle a damaged shipping
container or sensor head that contains a
radioactive source until you have discussed
the situation with the Honeywell-Measurex
Radiation Safety staff.
c. Tell the driver to record the nature and the extent of the damage on
both the carrier's copy and the delivery copy of the freight bill.

3. After inspecting the shipment and reporting any damage, move the
hardware into the installation area and unpack it.
4.2.1. Scanners
WARNING:
Scanners are heavy. To avoid
personal injury, use caution
when moving scanners, and
when unbolting and removing
the dollies.
1. Calculate and take into account the weight of the Model 2080 Scanner.
The weight of a scanner is approximately 5 pounds per inch of beam
length (between the end supports) plus 250 pounds (0.89 kg per cm plus
113 kg).
2. Move the scanner to the installation site before removing the packing
material.

3. If lifting eyebolts are installed in the upper beam, use chains and a
spreader bar to connect to the lifting crane.
4. If placing a forklift under the beams, first place two 2 x 6 wood backups
under the beam to avoid damaging the aluminum tracks.
Caution:
If the scanner is equipped with a “dirty
environment” kit, the carriage on the lower
beam can be crushed when the scanner is set
on the floor. Make sure that the scanner is
set on a pedestal or pads.
5. Ensure that the equipment is supported when the dollies are removed.
Caution:
Use care when unbolting and removing the
dollies. Scanner beams are aligned at the
factory. A drop of only a few inches onto a
hard surface could affect the alignment.
7. Save the packing material, if possible, and reuse it if the equipment is ever
moved.
WARNING:
The Basis Weight Sensor contains a radioactive source
(KR-85, SR-90, AM-241, or PM-147). OEMs or end users
who plan to conduct Basis Weight Sensor installation,
required safety tests, repairs, etc., are required to obtain a
Radioactive Materials License that explicitly authorizes
the operations to be conducted and names the individuals
who may do so. If an explicit Radioactive Materials
License cannot be obtained, operations of the type listed
above must be performed by authorized Honeywell-
Measurex employees or other appropriately licensed
individuals.
If you must store a Basis Weight Sensor head before it is mounted on a scanner,
you must place it in an access-restricted area controlled by licensed personnel,
such as a locked room or cabinet. If you must store a Basis Weight Sensor for a
period of weeks or months, you can usually arrange for Honeywell-Measurex to
store it for you. For more information, contact the Honeywell-Measurex
Radiation Safety Office.
WARNING:
During storage, a shipping shield must
always be bolted to each sensor head
containing a radioactive source.
This chapter contains installation information for the 2080-03 and 2080-13
Scanners. The instructions are presented in the order of the tasks to be performed.
The locations and names of signals that exit the scanner for the MSS enclosure
and the host computer system are discussed and described. However, specific
setup and connection instructions for the MSS enclosure and the host computer
system and sensors are not discussed. For details on those subjects, refer to the
documentation that came with your host computer system and/or sensor(s).
Before starting the hardware installation, verify that the site has been properly
prepared for the scanner. Refer to Part I of the Scanner Installation Checklist to
verify that everything has been completed and signed off. Use Part II to complete
the installation of the hardware.
WARNING:
The Basis Weight Sensor contains a radioactive
source (KR-85, SR-90, AM-241, or PM-147). OEMs
or end users who plan to conduct Basis Weight Sensor
installation, required safety tests, repairs, etc., are
required to obtain a Radioactive Materials License
that explicitly authorizes the operations to be
conducted and names the individuals who may do so.
If an explicit Radioactive Materials License cannot be
obtained, operations of the type listed above must be
performed by authorized Honeywell-Measurex
employees or other appropriately licensed individuals.
Details relating to the installation and alignment of the heads/sensors pass angle
adjustments and electrical connections are described in greater detail later in this
chapter.
Installation placement details are shown in Figure 5-1 (Sheets 1 thru 4) for
reference purposes only. Always use the latest revision of the installation
drawing (P/N 092080xxI) to keep track of any changes to the Model 2080-03 or
2080-13 Scanner that may have been made since this manual was published.
(Note the optional radiation light box 7.25 inches (184.2 mm) above the scanner.)
Scanners are often shipped with the heads already mounted and aligned by the
Honeywell-Measurex factory. Head alignment should be verified during scanner
installation. The procedure is detailed later in this chapter. Read the following
information before proceeding to align the heads or to verify their alignment. The
accuracy of measurement of the sensors depends on many variables. The
following simple precautions will help guarantee satisfactory performance.
The windows on the sensors must be kept as clean as possible. The cover on the
electronics end of the scanner must be kept in place, except when it is necessary
to access switches, wiring, or components. The heads are sealed to protect the
sensors and printed circuit boards. Head carrier tracks and wheels should be free
of dirt and debris. Compressed air is used with some sensors for cooling and/or to
keep dust and other contaminants from degrading sensor performance. Such air
must be dry and oil-free. Water-cooled sensors require water with low mineral
content and a neutral pH factor to avoid corrosion of metal parts. Water leaks can
seriously damage sensors.
For accurate scanning, the opposing heads must retain their alignment over the
full range of scan in both the forward and reverse directions. Special timing belts
are used to ensure that the cross-sheet alignment of the heads remains constant.
Beam alignment and track alignment are not required, and there are no jacking
screws for field alignment.
Heads must be aligned in the x-, y-, and z-axes. Adjusting the head alignment
along one axis may impact the alignment of the heads along one or both of the
other two axes. For this reason, it is recommended that when aligning the heads
you verify and/or adjust the air gap (z-axis) first.
Air gap adjustments are relative to the plane of sheet motion. The upper head
must be parallel to the sheet and to the lower head. One-half of the specified
spacing should be between the sheet and the upper head, and the other half below
the sheet as shown in Figure 5-3.
The head gap is calibrated for each system and must remain that calibrated size.
Each system is supplied with spacer (gap) bars the size of the correct head gap.
The Calibration Data Package has the correct gap size and related specifications
for the sensor in your particular system. Do not change the gap width on the
scanner from its originally calibrated size (as stated on the Honeywell-Measurex
Production Release form and Calibration packet) as this will cause the Calibration
Data Package to be inaccurate.
WARNING:
If the air gap of a sensor containing a radioactive
or X-ray source is changed from its original size
(for example, from a 0.4-inch gap to a 0.5-inch
gap), regulations require that a radiation survey
be performed and documented before the sensor
is put into use. This survey must be performed
by an individual who is specifically licensed to
perform this operation.
• Section 1 – Mounting the Heads assumes that the head is not mounted, and
that a complete Head Installation and Alignment is necessary.
• Section 2 – Aligning the Heads assumes that the heads have been mounted
and aligned on the scanner by Honeywell-Measurex before shipping.
WARNING #1:
The Basis Weight Sensor contains a radioactive
source (KR-85, SR-90, AM-241, or PM-147). OEMs
or end users who plan to conduct Basis Weight Sensor
installation, required safety tests, repairs, etc., are
required to obtain a Radioactive Materials License
that explicitly authorizes the operations to be
conducted and names the individuals who may do so.
If an explicit Radioactive Materials License cannot be
obtained, operations of the type listed above must be
performed by authorized Honeywell-Measurex
employees or other appropriately licensed individuals.
WARNING #2:
If the air gap of a sensor containing a radioactive
or X-ray source is changed from its original size
(for example, from a 0.4-inch gap to a 0.5-inch gap),
regulations require that a radiation survey be per-
formed and documented before the sensor is put into
use. This survey must be performed by an individual
who is specifically licensed to perform this operation.
The Radiation Safety Lamps are part of the radiation interlock system; if a lamp
burns out, it must be replaced before the head shutter can be opened again. The
red lamp is illuminated when the shutter is commanded open, and the green lamp
is illuminated while the shutter is closed. The red and green lamps operate
independently. If the red lamp is on, always assume that the head shutter is open
and that radiation is being emitted from the source head.
1. Push the Head Carriers to the offsheet end of the scanner. (All
adjustments and installations are carried out in the offsheet position.)
2. Loosen the pass angle clamps from the Head Adjustment Plate
(see Figure 5-4).
3. With the head arcs attached to the head assembly, rotate the head
assembly onto the Head Adjustment Plate.
4. Align the Bulkhead Board in the head to the side of the scanner through
which the Power Track cables and hoses feed (see Figure 5-4).
Caution:
When handling the sensor head containing the
radioactive source with the source window exposed
(no cover plate), keep the source window directed
away from yourself and others.
13. Verify that the head is at the correct height. Place a Gap Bar on top of
the Window Frame as shown in Figure 5-6. The middle of the Gap Bar
should be aligned (in the Z direction) with the Specified Product Path
Height as specified on the Scanner Installation drawing (see Figure 5-1).
If a small adjustment is required to bring the head to the correct height or to move
the lower head in the Y direction, perform the following steps. This assumes that
the Model 2080 Scanner is vertical or very nearly vertical, and that it has been
shimmed correctly (refer to Figure 5-1).
1. Loosen the four 3/8-24 retaining nuts on the Head Adjustment Plate.
2. Adjust the height of the head with the four 3/8-24 leveling nuts that
contact the Head Adjustment Plate.
3. If the pass angle of the heads is set to 0° and the path of the sheet through
the machine will be truly horizontal, it is useful at this point to level the
top surface of the head using the same nuts. Use a 2-foot or longer level
and check both the X and Y directions.
4. Tighten the four 3/8-24 retaining nuts. It is probable that this adjustment
will require additional minor modification to align the lower head to the
upper head.
5. For the nuclear Basis Weight Sensor, remove the Shipping (Radiation)
Shield from the head containing the source (normally the Upper Head).
6. Loosen the pass angle clamps from the Carriage Mounting Plate.
Caution:
After removing the Shipping Shield, be very careful
not to damage the sensor window. The window is
covered with a thin, electrically conductive coating.
7. Place the Upper Head on top of the Lower Head. The head separation
switch in the Upper Head should be aligned with the head separation
switch in the Lower Head, and both bulkhead boards in the heads should
be on the same side of the scanner (see Figure 5-7). If the specified air
gap is to be large, it may be best to place the Gap Bars on the Lower Head
first and then place the Upper Head directly on the Gap Bars.
8. Loosen the Pass Angle Clamps from the Carriage Mounting Plate.
10. Slide the lower head onto the Carriage Mounting Plate.
When your scanner was ordered, the head platforms were mounted using the
proper arc for the pass angle specified.
0° – 10° STANDARD
10° – 15° 07701500
07707300
15° – 60° 07701500
07707300
07705600
The pass angle is indicated on the Production Release form. To set the pass
angle, refer to Figure 5-9 and perform the following steps:
1. Move the heads to the offsheet end of the scanner. All adjustments are
carried out in the offsheet position.
3. Adjust the scanner’s height so that the sheet passes through the center of
the air gap between the heads.
4. Place a 4-foot (or longer) level against the end supports of the scanner
frame, and use the mount bolts and/or shims to adjust the scanner until the
end supports are vertical.
− If the pass angle is correct, the heads should be parallel to the sheet
path, and the string should be equidistant from both the upper and
lower sensor heads.
− If the pass angle is incorrect, loosen the pass angle clamps on the
upper and lower heads and rotate the heads into position.
5. If the pass angle is 0 degrees, place the small end of the alignment pin in
the small hole in the arcs, and rotate the head until the pin slides into the
hole in the pass angle clamp (see Figure 5-10).
1. Place the 2 Gap Bars between the Upper and Lower Heads as shown in
Figure 5-10. Make certain that optional hardware (for example, the sheet
guide extenders) is not interfering with the free movement of the gap bars.
(Note that gap alignment is done on the stainless window frames, not the
aluminum sheet metal cover.)
2. Check that the Upper Head is parallel to the Lower Head by carefully
sliding the Gap Bars between the 2 heads at the window frames and
checking for a loose or tight fit at different spots. Ideally, the bars will
just touch the window frames at all locations without binding. It is
acceptable for the periphery of the air gap to be slightly out of parallel;
however, a precise fit of the bars in the area of the sensor and receiver
window frames (in both the X and Y directions) is very important.
3. Adjust the air gap and/or Y alignment as necessary. With the Gap Bars
still in place between the heads, loosen the 3/8-24 retaining nuts and adjust
the 3/8-24 leveling nuts on the Head Adjustment Plate. Repeat the
procedure described in step 4 of Section 1 – Mounting the Heads.
4. For the fine and static adjustment of the heads, insert the 3 Alignment Pins
into the holes in the Plastic Housing of the sensor with the Head Cover
removed.
5. For the coarse and dynamic adjustment of the heads, insert the
3 Alignment Pins into the holes in the sheet guides as indicated in
Figure 5-10. When the heads are properly aligned to one another, the
pins will drop freely into the holes as the heads scan back and forth
along the scanner frame.
6. For coarse adjustment of the heads in the X direction, move the Lower
Head on the scanner as follows (refer to Figures 5-11 and 5-12):
b. Remove the cover from the Motor Drive end of the scanner.
d. Remove one of the loosened bolts and insert it into the threaded
hole between the clamping bolts. The flange is pressure-fitted to
the gear. Tightening the bolt you have just inserted will break the
flange free. Once the gear moves freely, replace the clamping bolt
to its original position.
e. Move the Lower Head until it is aligned with the Upper Head
and the Alignment Pins drop freely into place. If the pins do not
drop freely because of a Y offset, partially tighten the bolts on
the flange enough to hold the X alignment before making further
Y adjustments.
g. Once the heads are aligned with each other, fully tighten the
clamping bolts holding the flange to the drive gear. Alternately
tighten the mounting hardware on the upper and lower heads,
continuing to check that the Alignment Pins move freely.
7. For fine adjustment of the heads in the X direction, move the lower head
on the scanner as follows (refer to Figure 5-12):
a. Use a 7/16 wrench to loosen the four 1/4-inch bolts that hold the
Quick Disconnect Clamp to the Carriage Mounting Plate. The
upper head is now free to move within the slots in the Quick
Disconnect Clamp.
b. Move the head until the pins drop freely, then tighten the four
1/4-inch bolts.
Caution:
Be sure to remove the Alignment Pins
before moving the Heads. Failure to do so
can cause excessive strain on materials, and
permanently damage the heads and carriers.
8. Remove the Alignment Pins and push the heads to the other end of the
scanner, then replace the Alignment Pins and verify that the pins still drop
into place. If there is a misalignment in the X direction, perform the
following steps (refer to Figure 5-12):
a. Locate the belt tensioning bolt for the Upper Head inside the
Upper U-beam.
Caution:
A locking nut holds each belt tensioning
bolt. The belt will unwind around the
tensioning bolt if the bolt is not held while
the locking nut is loosened. Maintain at
least one full wrap of the belt around the
tensioning bolt.
Repeat this procedure with the belt for the Lower Head. If the heads still
do not stay aligned in the X direction from one end of the scanner to the
other, adjust the tensioning slightly so that the Lower Head can be moved
into alignment with the Upper Head (that is, so the Alignment Pins drop
freely into the alignment holes). Fully tighten the locking nut.
9. Run the Heads from one end of the scanner to the other several times.
Recheck the alignment using the Alignment Pins, and repeat the steps
listed above until correct.

fittings at the head. It is necessary to trace the water in/water out hoses from the
heads back to the scanner service bay. A simple way to perform this trace is to
blow pressurized air through the water hoses. Label the hoses temporarily.
Install air and water hoses into the appropriate ports. Make certain that the spring
clips on the fittings are properly seated.
Figure 5-13 shows the water plumbing for the scanner, and Figure 5-14 shows the
water in/water out ports and air connections for one model of scanner heads.
Refer to the installation document for details on your system. All possible head
plumbing connections are shown in Figure 5-14. Different sensors have different
connections. For example, the dedicated shutter air line is used on the Basis
Weight source, but not on the receiver or the IR sensor head.
Caution:
Keep all wiring and cables within
the footprint of the 2080-03 or
2080-13 Scanner, and avoid having
them rub on the scanner frame.
3. Remove the Bulkhead Board Cover on the upper and lower heads.
(See Figure 5-5.)
5. Install the wire covers and head covers, then realign the heads.
Figures 5-15, 5-16, and 5-17 show the cable termination details between the
MSS enclosure and the Scanner Termination Board as well as the part numbers
and color codes for the recommended cables.
The motor power termination is made at the scanner end and directly to the power
supply terminal block in the MSS enclosure. (See Figure 5-18.)
Note:
Analog inputs #6, #7, and #8 are optional.
5.5.3. Grounding
Proper grounding of a scanner is important both for safety and for reliable
operation. Scanners must be installed in compliance with Honeywell-Measurex
grounding specifications (refer to Chapter 3, “Preparing the Site”) and any
applicable local electrical codes. A good scanner installation includes the
following:
• The enclosure around the scanner must have a low impedance path to the
green wire safety ground.
• The distance from the scanner to a proper ground cannot exceed 100 feet.
2. Measure the resistance between the end of the frame ground wire you just
disconnected (not the frame) and the process machine (the plant).
Resistance must be less than 1 ohm.
5. Measure the resistance between the MSS enclosure and the process
machine (the plant). Resistance must be less than 5 ohms.
7. Measure the resistance between the scanner frame ground and the ground
of the host computer cabinet. Resistance must be less than 5 ohms.
This chapter presents maintenance information for the 2080-03 and 2080-13
Scanners and for some of the sensors they use. Refer to your sensor manuals
for detailed information on maintaining the sensors.
Note:
Read the information on switches
and their functions in Section 6.4.2.1,
“Scanner Switches,” before using the
switches to control the scanners.
WARNING:
Only personnel with radioactivity
detection badges should clean or
maintain the scanner. Minimize time
spent near the sensors. Be sure the
radiation shutter is closed when the
windows are being cleaned. Post a
notice at the host computer console to
guard against accidental startup.
6.1.1. Daily
The following preventive maintenance items for the system must be performed
daily:
• Inspect all water and air hoses and fittings, and repair any potential
problems.
• Check the head platform temperatures. These are shown on the MSS Card
IO Point monitor display from the MSS setup diagnostics. (Be sure to
select analog in, DAQ, and MSS number that corresponds to the scanner
and sensor in question.) This will read the raw analog voltages by channel.
To convert to °C, multiply by 10 (for example, 2.0V means 20°C). The
proper temperature for some types of heads is 100°F to 106°F (37.7°C to
41.1°C). Refer to the specific sensor manual for more information.
6.1.2. Monthly
The following preventive maintenance items must be performed monthly:
• Check the scanner power supply voltage output. Replace the power supply
if necessary.
• Check the air and water filters and flowmeters. Replace as necessary.
• Inspect and clean the scanner using the procedure described in Section 6.2,
“Monthly Inspection and Cleaning Procedure.”
• Check the head alignment. The upper and lower heads must maintain
coarse alignment over the full range of scan in both the forward and reverse
directions. Check the alignment using the Alignment Pins and Gap Bars.
Refer to the detailed procedures in Section 5.3, “Installing and Aligning the
Heads/Sensors.”
• Check the Emergency Stop Switch for function and possible loose
connections.
• Lubricate all bearings for the drive shaft and belt pulleys with standard mill
grease. Use care to prevent damage to seals.
Note:
The cavities will require more frequent
cleaning in some mill environments.
1. Set the Scan/Off Sheet switch to Off Sheet. The heads will move to the
offsheet position.
4. Inspect the cavities in the upper and lower U-beams for foreign material.
If the cavity is dirty or contaminated with scrap, blow the foreign material
out with compressed air and clean as needed.
5. Inspect the scanner carriage assembly for signs of wear on the head
carrier's wheels. Push the carriage to one side of the track and check that
the gap between the wheels and the other side of the track is between
.002" and .010". Wheel replacement is described in Section 6.3,
“Replacing Mechanical Assemblies.”
6. Inspect the drive belt for excessive wear, especially along the edges. If a
belt is excessively worn, it should be replaced. For replacing a drive belt,
refer to the applicable procedure in Section 6.3, “Replacing Mechanical
Assemblies.”
7. Test the idler pulleys at the cable end of the scanner for wobble (a sign
of wear). When idler pulleys are new, they have little, if any, perceptible
wobble. As they wear, wobble increases. As long as the air profile does
not change, the pulleys are probably not causing undue drag. When the
wobble exceeds 1/8 inch (or if the air profile changes erratically), the
pulleys should be inspected and replaced if necessary.
8. Inspect the Power Track for wear and for loose or broken links. Repair
and adjust cable dressing as needed. For replacing the Power Track, refer
to the applicable procedure in Section 6.3, “Replacing Mechanical
Assemblies.”
Caution:
The motor does not need to be oiled. If the
red plug on the side of the motor housing is
opened, oil will pour out.
Note:
It is a good practice to replace all
of the wheels at the same time.
1. Set the Scan/Off Sheet switch to Off Sheet. The heads will move to the
offsheet position.
1. Provide external support for the weight of the Upper Head. The Gap Bars
used together with shims may be of use.
2. Loosen the two 7/16-inch bolts on the same side of the Upper Head
Carrier (that is, the two 7/16-inch bolts that attach to the same Suspension
Bar, as shown in Figure 6-3). The Suspension Bar should now be
disconnected from the Upper Head Carrier.
3. Slide the Suspension Bar out from above the Upper Head Carrier and
remove it from the U-beam track.
(Note the location of bolts that require a wrench with 7/16-inch across flats.)
4. Remove the 1/2-inch bolt that holds each wheel to the Suspension Bar,
and replace each wheel. Make certain that the washer goes back between
the Suspension Bar and each wheel.
Caution:
Failure to properly replace the washer(s)
may cause the head assembly to seize during
scanning.
5. Replace the Suspension Bar in the U-beam above the Upper Head Carrier
and secure it with the 7/16-inch bolts. Do not fully tighten the bolts at this
time.
6. Repeat steps 1 – 5 above for the wheels on the other Suspension Bar on
the Upper Head Carrier.
7. With the weight of the Upper Head still externally supported, push the
Suspension Bars apart until they are snug up against each track. Tighten
the 7/16-inch bolts that hold the Upper Head Carrier to the Suspension
Bars. The head assembly should be free to slide in the track but have
minimal play in the sheet motion direction.
1. Remove the cable shield from around the Lower Head Assembly and
reposition the hoses and cables for easier access to the bolts under the
Lower Head Carrier.
3. Provide external support for the weight of the Lower Head Assembly,
then loosen the 7/16-inch bolts that fasten the Lower Head Carrier to the
Suspension Bars.
4. Replace the cable shield and return the hoses and cables to their original
position, taking care that they will not drag on the U-beam during the
scan.
1. Set the Scan/Off Sheet switch to Off Sheet. The heads will move to the
offsheet position.
3. Switch the scan control toggle switch (located on the Scanner Termination
Board) from COMPUTER to MANUAL.
1. Remove the locking nut from below the tensioning bolt. The belt will
loosen on the bolts.
2. One end of the belt is held in the slot on the tensioning bolt with
setscrews. Loosen them and take the belt off the tensioning bolt.
3. Use the Latch for Quick Head Separation to separate the Belt Buckle from
the carriage (refer to Figure 5-12.) The other end of the belt is held in the
Belt Buckle with setscrews. Loosen them and remove the belt from the
Belt Buckle.
4. Remove the belt from the scanner. The belt must be pulled out of the
U-beam, and must be removed from the pulleys on the cable end and
the motor end of the scanner.
5. Using the old belt to determine the length of the new belt, cut the new belt
to the same length as the old belt.
6. Slide the upper and lower head carriers all the way to the cable end of the
scanner.
7. Thread the new belt into the U-beam, replacing it through the cable end
and motor end of the scanner, so that the 2 ends of the belt can be
connected to the Belt Buckle.
8. Tighten one end of the belt to the Belt Buckle using the setscrews, and
tighten the other end of the belt to the tensioning bolt using the setscrews.
Be sure to maintain at least one full wrap of the belt around the tensioning
bolt, then replace the tensioning bolt in the Upper Head Carrier.
Note:
The belt must be attached as shown in Figure 6-4
or the head will not track properly, and the head
“quick disconnect” will not work.
10. Tighten the lock nut for the Belt Tensioning Bolt on the Upper Head
Carrier.
11. Readjust the head alignment as needed. For the head alignment
procedure, see Section 5.3.1.6, “Section 2 – Aligning the Heads.”
1. Check to make sure that the Scan/Off Sheet switch is still set to Off Sheet,
and that the scan control toggle switch is still set to MANUAL (refer to
Section 6.3.2, “Replacing Belts.”)
2. Use a 7/16-inch wrench to remove the 4 bolts that hold the Non Quick
Disconnect Belt Buckle to the Carriage Mounting Plate.
Repeat the steps listed in Section 6.3.2.1, “Upper Belt Replacement Procedure,”
keeping in mind that all references to the Upper Head Carrier will now indicate
the Lower Head Carrier. Be sure to follow the prescribed head alignment
procedure.
Note:
Replacing the Power Track requires major
disassembly of the 2080-03 and 2080-13 Scanners.
This procedure should be performed only by an
experienced Honeywell-Measurex technician. This
section provides an outline of the procedure for
informational purposes only.
To replace the 2080-03 and 2080-13 Power Track, perform the following steps.
With the exceptions noted below, the procedure is essentially the same for the
Upper and the Lower Power Tracks.
4. Disconnect the water and air hoses from the scanner head.
7. Put the Bulkhead Board Cover and the Head Cover back on.
8. Remove the 7/16-inch bolts that secure the Power Track Bracket to the
Carriage Mounting Plate. For the upper head and lower head assemblies,
refer to Figures 6-6 and 6-7, respectively. The Power Track should now
be disconnected from the head.
9. If the Upper Power Track is being replaced, disconnect the Power Track
from the Motor End Distribution Board. Also disconnect the Power Track
from the Scanner Termination Board.
10. Remove the two 7/16-inch bolts that hold the Power Track Support
Bracket to the cable end of the scanner (see Figures 6-8 and 6-9).
11. Clip the tie wraps that hold the water and air hoses to the Power Track and
to the Support Bracket. If the 24 VDC line and optional cables have been
bundled with the Power Track, cut these tie wraps also. Move these lines
aside.
12. Carefully pull the Power Track out from the U-beam through the hole in
the cable end of the scanner. It may be simpler at this point to cut the
water and air hoses. Use caution to avoid spilling water on the equipment.
13. Insert the new Power Track into the hole and slide the end up to the head.
Make sure that the end that is inserted into the hole is the end that
connects to the head, not to the termination board.
14. For the Upper Power Track, connect the electrical lines to the Motor End
Distribution Board.
15. Connect the new Power Track hoses and cables to the Carrier Bracket with
tie wraps.
16. Place the bracket at the end of the linkage on the Power Track.
17. Connect the Carrier Bracket to the Carriage Mounting Plate using the
three 7/16-inch bolts.
18. Connect the air, water, and electronics to the head (see Figure 5-14).
20. Check that there is sufficient clearance for the cables and hoses on the
Power Track.
Switch Function
Emergency Stop Button This switch stops head motion by interrupting the 24 VDC supply to the motor
controller. To release, turn the button clockwise as indicated by the arrows, and
it will pop back out.
The Emergency Stop Button will clear some faults caused by accidental system
interrupts (for example, when the scan head is physically jammed). Clear the
cause of the fault, set the Scan/Off Sheet switch to Off Sheet, depress the
Emergency Stop Button, wait 20 seconds, and release the button. The heads
should move to the Off Sheet position and be ready to resume scanning.
Scan/Off Sheet Switch Setting the switch to the Off Sheet position closes the shutters and stops
scanning. The heads will move to the offsheet position, and head motion will
cease.
Setting the switch to the Scan position permits the operator to initiate scanning.
The shutters will open, the software will check that the heads are measuring
within certain calibration limits (the “flag to air ratio”), and scanning will
resume. If the ratio is out of limits, the system will check the total of attempts,
and declare a fault if the out-of-limits condition remains.
The Scan/Off Sheet Switch also functions to manually control forward and
reverse motion of the scanner heads. See the description of the
Computer/Manual Toggle Switch below.
Reference/Sample Switch The Reference Switch operates only when the heads are offsheet or in single-
point scan. When set, it allows compensating factors used in measurements to be
updated. If no sensor is specified before the switch is set, software defaults to the
4203 Basis Weight Sensor.
The Sample Switch operates only when the heads are offsheet or in single-point
scan. When set, it initiates a measurement of a sample.
When either Reference or Sample is selected, a lamp comes on in the switch and
remains on until the selected operation is completed.
Computer/Manual Toggle This switch is located on the Scanner Termination Board (see Figure 6-1).
Switch It allows the operator to change control of the head motion from computer
control to manual control. The Scan/Off Sheet Switch should be set to the
Off Sheet position before the Computer/Manual Switch setting is changed.
Caution:
Changing this switch setting without first
moving the heads to the offsheet position
will cause a system fault.
When this switch is set to Manual, the function of the Scan/Off Sheet Switch
changes so that it will now control forward and reverse motion of the heads.
Table 6-2 lists the system switches and describes their functions. The status of
the system switches is indicated by LEDs on the Scanner Termination Board.
Switch Function
Head Limit Switches These are magnetically operated by the sensor heads. If the software fails to
recognize an edge-of-sheet signal and remove the ON command, the heads
continue to move until a limit switch is reached. If either limit switch closes,
software reverses the motor and scanning resumes in the opposite direction.
Preset Switch This switch is magnetically operated by the upper head and is located in the
center of the scanner.
Limit Switches These switches are magnetically operated by the sensor heads. They are used by
the software to determine absolute head position.
Table 6-3 describes the function of the LEDs on the Scanner Termination Board.
• Set the jumpers and/or switches of new boards exactly as they are
positioned on the replaced board.
Figure 6-10. Scanner Installation Connection for Basis Weight and IR Sensors
(Sheet 1 of 2)
Figure 6-10. Scanner Installation Connection for Basis Weight and IR Sensors
(Sheet 2 of 2)
The 2080-03 and 2080-13 Scanners support the following primary sensors
at this time:
• IR Sensor
The 2080-03 and 2080-13 Scanners support the following secondary sensor
at this time:
• Z-Axis Sensor
WARNING:
If the air gap of a sensor containing a
radioactive or X-ray source is changed from its
original size (for example, from a 0.4-inch gap
to a 0.5-inch gap), regulations require that a
radiation survey be performed and documented
before the sensor is put into use. This survey
must be performed by an individual who is
specifically licensed to perform this operation.
For more information, contact the Honeywell-
Measurex Radiation Safety Department.
• Avoid removing the head cover until it is determined that the sensor is not
working properly.
• Inspect the log of standardizations that are run daily for error trends. This
can help you catch potential problems and repair them during scheduled
downtime.
• If your employer has assigned you radiation badge(s), wear the badge(s).
Do not proceed if required badge(s) are unavailable.
• If the sensor head contains X-ray source(s) only, turn off power to X-ray
tube(s) and remove the key. Do not return the key or reapply power until
sensor heads are returned to their normal configuration.
WARNING:
Regardless of the method used to close
shutter(s), take time to verify that the shutter(s)
are actually fully closed by following the 2 steps
listed below. This is very important due to the
high radiation levels that exist when the shutter
is open and the possibility of serious injury,
particularly to the skin, within a period of
seconds or minutes.
• If possible, request background counts and verify that they are within the
normal range for shutter closed. (Honeywell-Measurex employees should
refer to the section on “Troubleshooting High [Low] Shutter Closed [Air]
Counts” in the Radiation Safety Training Manual for Honeywell-Measurex
employees (P/N 44070004).
WARNING:
If the “shutter closed” counts
are unusual, do not proceed.
• Observe warning lights if the system is powered up; only green lamps
should be lighted. Do not proceed if the green lamps are not lighted!
WARNING:
If both green and red lamps
are lighted, do not proceed!
• Unless head power is required for the planned operations, turn off the head
power and tag the console so that no one will restore power until you are
through.
• Carefully separate heads (keep hands and all body parts away from the
source windows) and remove the head cover from the source sensor head.
• Unless access to one of the sensor windows is required, realign upper and
lower heads opposite to one another and/or attach the cover plate over the
radioactive source window.
• Note that the dose rate through the closed shutter will exceed the natural
background rate, although it will be just a small fraction of the shutter open
rate. This is normal and unavoidable, and is not a sign of shutter
malfunction or shutter design failure.
• If your employer has assigned you radiation badge(s), wear the badge(s).
Do not proceed if required badge(s) are unavailable.
• Observe the warning lights and confirm that all red SHUTTER OPEN
warning lights are off and that all green SHUTTER CLOSED lamps are
lighted. Do not proceed if the green lamps are not lighted!
WARNING:
If both green and red lamps are
lighted, do not proceed!
• If your employer has assigned you radiation badge(s), wear the badge(s).
Do not proceed if required badge(s) are unavailable.
• If the sensor head contains X-ray source(s) only, turn off power to X-ray
tube(s) and remove the key. Do not return the key or reapply power until
sensor heads are returned to their normal configuration.
WARNING:
Regardless of the method used to close shutter(s),
take time to verify that the shutter(s) are actually
fully closed by following the 2 steps listed below.
This is very important due to the high radiation
levels that exist when the shutter is open and the
possibility of serious injury, particularly to the skin,
within a period of seconds or minutes.
WARNING:
If the “shutter closed” counts
are unusual, do not proceed.
2) Observe warning lights if the system is powered up; only green lamps
should be lighted. Do not proceed if the green lamps are not
lighted!
WARNING:
If both green and red lamps
are lighted, do not proceed!
• Turn off the head power and tag the console so that no one will restore
power until you are through.
• Carefully separate heads (keep hands and all body parts away from the
source windows).
• If the window to be replaced is on the source sensor head, keep hands out
of the area directly above or below the Kapton window during the entire
replacement process.
• Inspect the replaced windows carefully to ensure that they are not
damaged.
Note:
The Basis Weight and X-ray windows are coated
with a conductive coating that faces the air gap, not
the inside of the sensor head. Use an ohmmeter to
find the conducting surface when replacing the
windows. Be careful not to scratch or pierce the
aluminized coating; use the flat side of the test
probes, not the tips.
This appendix contains the Installation Checklist for the Model 2080-03 and 2080-13 Scanners.
A copy of this checklist should be used when installing the scanners.
There are 2 possibilities for U.S. shipment of nuclear sensors when OEMs are
involved: Honeywell-Measurex may ship the sensor to either the end-user site or
an OEM site. From a regulatory standpoint, shipping to an end-user site involves
the least difficulty for Honeywell-Measurex, the OEM, and the end user.
Regulatory considerations for both options are described below.
Issue #1:
The end user, not Honeywell-Measurex, must have a license for the
possession and eventual use of the sensor. This is a requirement
regardless of device ownership or whether system acceptance tests have
been completed [10 CFR 30.3].
Note:
Honeywell-Measurex has a Specific License that permits trained
and badged employees to conduct service (installation, certain
radiation safety tests, and maintenance) on Honeywell-Measurex
sensors at General Licensee sites. However, there are only a few
special cases where a Honeywell-Measurex license can cover
possession and use of a nuclear sensor outside of the Cupertino
facilities. For example, Honeywell-Measurex is permitted to
apply for a limited type of temporary off-site license for industry
trade shows.
Issue #2:
The end-user license can be one of two types: the automatically granted
General License or a Specific License [10 CFR 30.31]. A large majority
of Honeywell-Measurex customers in the U.S. have a General License.
(Refer to Section B.3, “Radioactive Materials Regulations,” for a further
explanation of these license types.)
Issue #3:
Both Honeywell-Measurex and the end user are required to report
specified details of the sensor transfer to various authorities [10 CFR
31.5(c)(8), 32.52]. This means that before the sensor ships from
Honeywell-Measurex, the Honeywell-Measurex Radiation Safety Office
must be given the end user’s name and the address where the sensor will
be located.
Issue #4:
All Generally Licensed end users are required to have certain radiation
safety checks performed upon receipt of a sensor and periodically
thereafter. These tests must be performed by a person who holds an
appropriate Specific License [10 CFR 31.5(c)(3)].
Issue #5:
All Generally Licensed end users are required to have "installation,
servicing, removal from installation, involving the radioactive materials,
its shielding or containment" performed by a person who holds a Specific
License for these operations [10 CFR 31.5(c)(3)].
Note:
The Honeywell-Measurex Radiation Safety Office
has encountered a variety of interpretations of the
wording above. Local regulatory authorities should
be contacted in situations that are unclear.
Issue #6:
The requirements in Issues #4 and #5 also apply to Specifically Licensed
end users. However, some Specifically Licensed end users may be
licensed to perform some or all of these operations themselves.
Issue #7:
If an OEM, rather than Honeywell-Measurex personnel, will be
performing radiation checks as described in Issue #4, the OEM must have
a Specific License that explicitly authorizes the operations that are to be
performed [10 CFR 30.34(c). 31.5(c)(3)].
Issue #8:
If the OEM, rather than Honeywell-Measurex personnel, will be involved
in system installation, the OEM should either have a Specific License for
the intended operations, or should comply with the applicable regulation
[10 CFR 30.34(c), 31.5(c)(3)]. If the OEM performs work that requires a
Specific License but does not have one, both the OEM and the end user of
the nuclear sensor will be in violation of regulatory requirements.
B.3.2. Licensing
There are 2 types of radioactive materials licenses that Honeywell-Measurex
customers may hold:
• General License
• Specific License
Item #1:
Maintaining the warning labels on the sensor head and complying with the
instructions provided on the labels.
Item #2:
Having the radioactive source(s) tested for leakage (Kr-85 sources do not
require leak testing) and the on-off mechanism (shutter) and warning
lights tested at 6-month intervals.
Note:
This testing must be conducted by a person
who holds a Specific License to perform
such tests on Honeywell-Measurex
equipment.
Item #3:
Not permitting anyone who does not hold a Specific License to perform
installation, servicing, or removal if it involves the radioactive source, its
shielding, or containment.
Item #4:
Maintaining records (which include the dates and names of the persons
performing such work) of testing, servicing, and installation involving the
radioactive source.
Item #5:
Suspending operation of the sensor immediately in the event of detection
of removable radioactive material (leakage) or failure or damage that
affects the shutter, warning lamps, and shielding until the sensor is
repaired or replaced by a person holding a Specific License.
Item #6:
Furnishing a complete description of the occurrence to the regulating
agency following damage or failure (as described in Item #5).
Item #7:
Not abandoning, disposing of, or transferring the sensor except to
someone authorized by a Specific License to receive the sensor.
Item #8:
Maintaining records of all receipts, transfers, or disposals of radioactive
material.
Item #9:
Notifying the regulatory authority of receipt or transfer of a sensor
containing radioactive material.
Item #10:
Notifying the regulatory authority of radiation incidents, theft, or loss of
radioactive material.
For firms that have contracted with Honeywell-Measurex for continuing service,
Honeywell-Measurex will provide support in radiation safety. Review the service
contract for details.
The discussion of the regulations presented above is not a legal opinion and is
intended as a general guide only. To determine the actual requirements that
apply, Honeywell-Measurex recommends consulting the applicable licenses and
the NRC or state regulations.
