Important Safety Notices about Using the Micro-Tech

Please note carefully the following safety warnings and notices.

Safety in Transportation and Handling

The Micro-Tech is an integral part of your plant and when transporting, handling, and installing the unit, your
own plant safety instructions must be applied. Because your Micro-Tech and associated systems are tailored
to application requirements, it is impossible to be precise about product mass/weight. If precise values are
required, the shipping crate will be marked with the overall shipping mass of the product and this may be used
as a reasonable guideline.

Safe Practices During Use, Maintenance, and Repair

This manual contains details, as appropriate, including the appropriate tools. However, because of its
importance, the warning contained in the installation section is repeated here.

TO GUARANTEE PERSONAL SAFETY, CARE MUST BE TAKEN WHEN WORKING ON OR
AROUND THE MICRO-TECH. AS WITH ALL SUCH DEVICES THE MAIN SUPPLIES (ELECTRICAL
AND OTHER) TO THE SYSTEM MUST BE LOCKED OFF WHEN PERFORMING REPAIR O R
MAINTENANCE WORK. AFTER DISCONNECTING, SWITCH OFF AND LOCK THE ELECTRICAL
SUPPLY.

Training Needs of Users

We offer all customers full training for operations and maintenance staff.

Low Voltage Directives

All of the recommendations for LVD apply to the prevention of electrical shock. If access to the electronics
enclosure is required, the incoming AC power supply should be isolated remotely and locked-off. Access to
the electronics enclosure by untrained personnel is not recommended.

Circuit Breaker

The Micro-Tech should be permanently connected to its AC supply. Please ensure that when installing the
Micro-Tech, a switch or circuit breaker is used and is positioned close to the Micro-Tech in easy reach of the
operator. The switch or circuit breaker shall be marked as the disconnecting device for the Micro-Tech.

DO NOT install the Micro-Tech in a position that makes it hard to use the AC mains isolator.

Thermo Fisher Scientific Warranty

in material and workmanship. Such warranty shall not apply to accessories, parts, or material purchased by the

seller unless they are manufactured pursuant to seller's design, but shall apply to the workmanship
incorporated in the installation of such items in the complete equipment. To the extent, purchased parts or
accessories are covered by the manufacturer's warranty; seller shall extend such warranty to buyer.
Seller's obligation under said warranty is conditioned upon the return of the defective equipment,
transportation charges prepaid, to the seller's factory in Minneapolis, Minnesota, and the submission of
reasonable proof to seller prior to return of the equipment that the defect is due to a matter embraced within

as such alleged errors or defects are discovered by purchaser and seller is given opportunity to investigate and
correct alleged errors or defects and in all cases, buyer must have notified seller thereof within one (1) year
after delivery, or one (1) year after installation if the installation was accomplished by the seller.

Said warranty shall not apply if the equipment shall not have been operated and maintained in accordance
with seller's written instructions applicable to such equipment, or if such equipment shall have been repaired
or altered or modified without seller's approval; provided, however, that the foregoing limitation of warranty
insofar as it relates to repairs, alterations, or modifications, shall not be applicable to routine preventive and
corrective maintenance which normally occur in the operation of the equipment.

The Micro-Tech has been properly packaged for shipment at the factory.
Please inspect all packages for damage before opening the shipping
package, because the carrier is likely responsible for any damage. Once
removed from the package, the Micro-Tech can be safely stored with its
cover and latches secured and with the hole plugs installed. During
storage, do not expose the Micro-Tech to moisture or to temperatures
outside the range of –22 to +158°F (–30° to +70°C).

The Micro-Tech Integrator is a microcomputer-driven instrument used
for deriving rate and quantity of flowing material from signals
representing the weight of a segment of moving material and its
velocity. By processing, these two input signals, the Micro-Tech delivers
visible and electrical outputs representing the rate of material movement
as well as visible and electrical outputs representing the total amount of
material that has passed the weighbridge.

For remote indicating, four options are available, as follows.

Hardware Installation

Mount the Micro-Tech to a rigid, flat, vertical surface using four
mounting holes provided on the back of the enclosure. Care should be
taken to ensure the mounting surface is flat, so as not to twist or warp
the fiberglass enclosure when tightening the mounting bolts.

To connect the incoming power, use the following procedure. Please
note that all units shipped from the factory are configured for 100 to 240
VAC.

1. A customer-supplied 2 amp 250 VAC normal-blow fuse must be

connected in the “hot” power lead between the AC Mains and the

Micro-Tech “AC Power Input” terminal block.

2. Unlatch and open the enclosure door.

3. Route incoming power wiring through a conduit hole at the bottom

right of the enclosure. For North America locations a certified Nema

4/4X bushing must be used for openings. For other locations see

your local Electrical Authorities. Leave ample loose wiring

(typically 8 inches / 20 cm) to facilitate removing the terminal

connectors.

4. Locate the wiring panel (see Figure 1–4 below), which lies on the

underside of the electronics enclosure. The wire-safety ground-

terminal is located on the enclosure back panel.

5. Wire HOT to Terminal H on the AC PWR IN terminal.

6. Wire NEUTRAL to Terminal N on the AC PWR IN terminal.

7. If additional I/O is required at the line voltages, these wires should

be routed through a conduit hole on the bottom right of the

enclosure. Leave ample loose wiring (typically 8 inches / 20 cm) to

facilitate removing the terminal connectors.

The Micro-Tech has been designed for belt scales and is capable of
performing all of the necessary measuring functions. All of the required
functions are resident in the software of the microprocessor. Optional
functions are automatically turned on when the relevant hardware is
installed, or after the operator has selected them through the keypad.
Setup of the Micro-Tech is easy and is performed from the keypad on
the front of the device. The setup parameters may be divided into the
following main groups.

 Menu 1: Calibration
 Menu 2: Set-up
 Menus 3–6: Options set-up

The Integrator can be directly connected to six 350 ohm load cells and
receives the signal of a speed sensor in order to calculate belt speed, belt
loading, and feed rate.

Rate is integrated in time to calculate the amount of material conveyed
by the belt (total), and is displayed in three individual registers: total,
reset total, operator total. The Integrator can perform automatic zero and
span calibrations. When the belt is running and the rate is below a
certain percentage, the Integrator can perform auto zero tracking, to
minimize the error of zero due to material and dust. Analog (current)

output signals or communications can be used to transmit rate, speed or
belt loading to other control devices. Displayed variables and analog
outputs can be smoothed via damping filters, individually
programmable.

The Integrator includes internal diagnostics that generate alarms in case
of hardware failures or programming errors. The following process
alarms are also provided.

 Belt slip.
 Alarms for high and low flow rate, speed, and load.

Digital outputs are also provided for the following.

 Hardware failure
 Alarm cumulative

Alarms are visible on the display and can be acknowledged and reset
through keypad, digital input, or serial line. Alarms can be delayed to
avoid intervention in case of short time peaks. Each individual alarm can
be programmed to operate as alarm, shut down, or ignored. Two LEDs
indicate the cumulative status of alarms and shut down.

Timed or command prints can be obtained by connecting a serial printer
to the Comm output on the motherboard, or an optional communication
board. Data may also be downloaded to a USB memory device. Time
and date are permanently stored in the battery-backed memory. The
integrator Set-Up, Totals, Zero results, and Audit Trail of the instrument
can be printed.

There are two communication ports on the Motherboard. Comm A is
RS232C/RS-485 (jumper selectable), isolated. Comm B is RS-485 only,
non-isolated. One additional communication board may be installed. For
detailed descriptions of communication protocols, see Appendix C.

There are three types of standard communication functions, as described
below.

Capabilities

Rate

Calculation

Flow Totalization

Overview of Capabilities

 Serial Communications

The communication protocol allows a remote intelligent device to

read the contents of the registers and write to some registers. During

the communication activity, the Micro-Tech always acts as a Slave,

meaning it responds to a request from a Master device on the line,

but never attempts to send messages out. One electrical interface

may be selected and accessed through one communication port.

 Field Bus I/O

Profibus-DP I/O communication protocol board is typically used to

transfer I/O images between a main PLC and the remote devices

(normally remote I/O racks—rack adapters) or to transfer (re a d and

write blocks of data with intelligent remote devices (node adapters),

the Micro-Tech in this case. The Remote I/O is a typical

master/slave communication where the main PLC is the master or

scanner and the remote devices are slaves or adapters.

 Ethernet Port

The Micro-Tech has a built-in Ethernet port. Communications

protocols Ethernet/IP and Modbus/TCP can be used. The Micro-

Tech is a slave device only, and cannot initiate messages.

Flow-

This section describes technically, how the Micro-Tech performs each
particular duty.

The signal measured by the load cell(s), which represents the weight per
unit length of the belt (lbs/ft), is multiplied by the signal measured by
the speed transmitter, which represents the belt speed (ft/min). The result
of this operation is the instantaneous flow rate (lbs/ft x ft/min = lbs/min)
that is then multiplied by suitable constant to obtain the value in the
required engineering units (kg/h, ton/h, etc.). An adjustable damping
filter is provided separately for displayed rate and current outputs.

Thermo Fisher Scientific Micro-Tech 9101/9201 Reference Manual, Rev J 1-15

Introduction

Automatic Zero

and Span

Calibrations

Overview of Capabilities

The total is accumulated by multiplying weight per unit length times the
incremental length and totalizing the result in engineering units. Three
totalizing memories are provided, as follows.

 The first memory (Master Total) is not re-settable to guarantee the

data is not lost because of unwanted reset.

 The second and third memories (Reset and Operator Total) are re-

settable by the operator and are normally used for shift or daily
totalization.

Zero and span calibrations are based on belt length defined by a number
of belt revolutions. To calculate the exact number of revolutions, the
instrument counts the pulses delivered by the speed transmitter (one
pulse represents a specific belt length).

When the required number of pulses is reached, the instrument ends the
calibration test, and compares the actual totalized value to the theoretical
one (0 for zero calibration), and calculates the calibration error.

 Electronic Calibration (R-Cal)

Allows the user to perform the calibration without the need for
applying test weights or test chains on the weighbridge. It is
performed by unbalancing the load-cell bridge using a precision
resistor. The calibration constant is calculated based on the load cell
and the scale data.

 Test Weight Calibration

Requires the positioning of test weights on the weighbridge.

 Chain Calibration

Requires the application of calibrated chains on the belt. This
method is the nearest to actual operating conditions.

 Material Test

Allows you to run material of known weight over the scale to check
the accuracy of your scale. Alternatively, you can run material over
the scale, then have it re-weighed by another reference scale.

Introduction

Auto Zero

Tracking

Optional

Outputs

Optional Signal Outputs

Auto zero tracking (AZT) enables the belt scale system to automatically
zero itself during extended periods when the conveyor belt is running
empty. AZT does not actually change the Zero Number but applies a
factor to the Zero Number. AZT is menu selectable because some
installations may not need this option. A “Z” displays on the second line
of the display to indicate the selection of this option.

Under a preset minimum flow rate when enabled, the instrument makes
subsequent automatic zero calibrations with the following sequence.

1. Waits for one-half time of the test duration (a solid “Z” displays).

2. Execution of a zero test (the “Z” flashes).

3. Performs automatic zero for one test duration.

Signal

4. Continuously repeats above zero calibration as long as the feed rate

remains below AZT preset value. The Zero Tracking function is

limited to a maximum value of Deviation that is set as a percent of

full scale in the Setup scroll. If the new zero calculated by auto zero-

tracking function exceeds that value, an alarm is generated and the

new zero is not installed. The Zero Reference value for AZT is set

initially at the first zero calibration after cold start. An alarm is

generated when new zeros deviate too far from the Zero Reference

value. The Zero Reference value must be reset to clear these

deviation alarms.

An optional current output signal (0-20/4-20/20-0/20-4 mA) and an
optional dual channel current output/analog input board are available.
The choice of the signal type is made through the keypad. Each current
output may be programmed via the keypad to deliver one of the
following signals

 Flow rate
 Belt loading
 Belt speed

Each output has its own adjustable damping and programmable time or
length delay.

Overview

Initializing the Micro-Tech

This chapter tells you how to start up your Micro-Tech, initialize its
software, and get your Micro-Tech and its associated scale up and
running. As part of the initialization process you will perform a belt­length test and, once this is done, do the initial zero and span calibrations
of the scale. Your Micro-Tech is then ready to go into operation.

There are five basic steps in the initialization process, as follows.

 Determine the correct “belt-scale code” of the conveyor scale the

Micro-Tech is working with.

 Acquire some basic conveyor and scale information—such as idler

spacing, conveyor angle, and so forth.

 Determine the exact belt length of the conveyor.

 Enter your belt-scale code and other conveyor and scale parameters

into the Micro-Tech to initialize the software.

 Complete the initial scale (zero and span) calibrations.

Easy Route

Determining the Belt-Scale Code

the Belt-

It is critical that you know the correct belt-scale code of the conveyor
and scale the Micro-Tech is working with, for the following reasons.

 The scale may produce inaccurate and unreliable results if you use

the wrong belt-scale code.

 The Micro-Tech software uses a belt-scale code that is specific to

each particular system, and this belt-scale code must be entered
during the software initialization process.

 Knowing the correct belt-scale code will minimize the amount of

time and effort needed to set up the Micro-Tech.

 Non-pivoting scales have far fewer required set-up parameters than

pivoting scales. As a result, if you have a non-pivoting scale (with a
belt-scale code of 49, for example), there are only 11 required
parameters. In contrast, if you have a pivoting scale (with a belt-scale
code of 1, for example), there are 18 required parameters. So,
knowing your belt-scale code in advance will make the whole set-up
process go more smoothly.

The quickest and easiest way to determine the belt-scale code of the
scale the Micro-Tech is working with, is to look at the Micro-Tech
“System Data Sheet” or “Door Label.”

 System Data Sheet

A System Data Sheet is supplied with the product documentation
that accompanied your unit. See Appendix A for an example of a
typical System Data Sheet.

 Door Label

A Door Label is supplied with every Micro-Tech. For panel­mounted versions of the Micro-Tech, the Door Label is in the
product documentation that accompanied your unit. For field­mounted versions, the Door Label is glued inside the main door of
the enclosure. See Appendix A for an example of a typical Door
Label.

Now that you know the correct belt-scale code of the scale you are
using, you are ready to collect some additional data about the type of
conveyor and scale you are using at your particular facility. You will
need this information when you initialize the Micro-Tech software, and
can save time and effort by gathering this conveyor data now rather than
later.

The type of scale and conveyor you have installed at your facility
determines the number and type of parameters you need to enter when
initializing the Micro-Tech software. As a general rule, non-pivoting
scales have fewer required parameters than pivoting scales. Clearly, we
cannot list every single scale configuration in this manual, so we will
restrict ourselves to showing you two examples to give you a feel for
how the belt-scale code works and how it determines what parameters
you need to know when initializing the software.

The Speed Input parameter tells the Micro-Tech whether your conveyor
system is equipped with one (or, in some special instances, two*)
optional speed sensors. An optional speed sensor feeds very precise
conveyor speed readings to the Micro-Tech. If you did not order an
optional speed sensor, enter “simulated” in Table 2–1 or Table 2–2.

* Two speed inputs, typically, are used in systems equipped with two
scales.

In summary, your choices for speed input are as follows.

 Single—Your conveyor is equipped with one speed sensor.
 Two—You have two scales, each equipped with a speed sensor.
 Simulated—There is no speed sensor attached to your conveyor.

Note, however, that a conveyor-run digital input is required for the
simulated option to work.

Test Duration

Example

Test Duration

You are now going to measure how long it takes for the belt in your
conveyor system to make one revolution at maximum speed. You will
use this information to verify that the scale’s zero and span can be
properly set during the approximately six minutes it takes the Micro­Tech to complete the zero-calibration procedure and span calibration
procedure.

The take-home message here is that, for the scale’s zero & span to be
accurate, the zero and span calibration procedures must fulfill the
following requirements.

 The belt must make at least three complete revolutions.
 The test must have a total running time of six (or more) minutes.

To help you work through the necessary calculations, here is a real-life
example.

We have just finished installing a 56ft-long conveyor at our facility that
has a belt length of 120 feet—that is, if the belt was removed from the
system, cut and laid out flat, it would extend to 120 feet. Next, we need
to know how long it takes for the belt to make precisely one revolution
when running at maximum speed.

1. To do this, we drew a prominent chalk line across the belt directly

above the load cell, and timed (to the nearest second) how long it
took for the belt to make exactly one revolution. We discovered it
took precisely 1 minute and 15 seconds. Thus,

—Time for completing one revolution = 75 seconds.

2. Six minutes contain 360 seconds (6 x 60 seconds). So the number of

revolutions the belt makes in 360 seconds is 4.80 (360/75).
—Number of belt revolutions made in 6 minutes = 4.80

Thermo Fisher Scientific Micro-Tech 9101/9201 Reference Manual, Rev J 2-11

—Revs rounded up to the nearest whole number = 5

Initializing the Micro-Tech

Manually

Determine Test

Duration

Test Duration

(If this number is less than 3, you must lengthen the time of the
test so that the belt completes the required minimum of three
complete revolutions.)

3. Because one belt revolution takes 75 seconds to complete, it takes

375 seconds (5 x 75) to complete the required test revolutions. Thus,

—Time to complete the test revolutions = 375 seconds

4. In summary, the data we have collected so far is as follows.

—Belt length = 120 feet
—Time for one belt revolution = 75 seconds
—Number of revolutions needed for test = 5
—Time to complete the five test revolutions = 375 seconds

5. Now it’s your turn to collect your own data and enter it into Table

2–1 or Table 2–2.

You are now going to collect data from your own particular conveyor
system to determine the Test Duration. Here’s how.

1. Using a 100 ft tape measure, measure the length of the belt to the

nearest 0.1 feet. Enter the result for “Belt Length” in your
“Initialization Data Summary,” Table 2–1 or Table 2–2.

2. When the belt is stationary, draw a chalk line across the belt.

3. Start the belt and wait until it is running at maximum speed.

4. Use the chalk mark to time one complete revolution of the belt. Enter

the result (in seconds) in Table 2–1 or Table 2–2.

5. Calculate (to at least one decimal place) the number of revolutions

the belt makes in six minutes—as described in the example above.
Round up the number of revolutions to the next whole number. Enter

The first time you power up the Micro-Tech, you are doing what is
known as a “cold-start.” Once the Micro-Tech is up and running, you
can use the cold-start procedure (described below) to—in computer
terms—“reboot” the Micro-Tech. In other words, when you do a cold
start, the Micro-Tech’s RAM memory is erased and everything is
returned to its initial start-up state. As a result, cold-starts are used, for
example, to restore all the Micro-Tech settings from a previously made
back-up flash drive.

To cold-start the Micro-Tech, do the following.

1. Turn on the Micro-Tech’s power switch while simultaneously

pressing and holding soft-key #1 and the Run button. (See Figure 3–
1 for the location of these buttons.)

2. The Micro-Tech starts up, and the Alarm LED will light to indicate

This chapter describes the Micro-Tech console and tells you how to

There are four major parts to the Micro-Tech console, as follows.

 Display screen
 Keypad
 Soft keys

This displays the built-in Micro-Tech menus as well as any entries you
make using the keypad. The display also shows the current functions
(such as Edit, Enter, and Clear) that are assigned to the four Micro-Tech
soft keys situated below the display.

The keypad allows you to scroll through the Micro-Tech menus, enter
numbers and letters into the Micro-Tech’s menus, and control the
operation of the Micro-Tech using the Run button. As you will already
have noticed—similar to the keys on a cell phone—the Micro-Tech’s
number keys have multiple uses. All are context sensitive, meaning, for
example, that when the Micro-Tech is displaying a menu, the number
“8” key operates as a down-arrow key, but when the Micro-Tech is
expecting you to enter a number, it operates as an “8” key. Similarly, in
the print menu, when you are naming your output, repeatedly pressing
the “8” key brings up, in succession, the letters V and W.

 Arrow Keys

The up-arrow and down-arrow keys allow you to scroll through the
Micro-Tech menu screens—up and down as well as left and right in
some menus.

 Control Keys

The Micro-Tech has two control keys—the Menu button and the
Run button. Once the Micro-Tech is up and running, pressing the
Menu button brings up the menu screens. Pressing the Run button
returns the Micro-Tech to its normal operating mode.

The four blue keys below the display screen are “soft keys,” that is, they
have different functions depending on which menu you are using. The
soft keys are assigned to various menu-selection and data-entry
functions—such as Edit, Clear, Reset, Totals, and so forth.

This works like the odometer on a vehicle, and records the total
amount of weight that has crossed the scale since the Micro-Tech
was first put into operation. And, like a vehicle’s odometer, it can be
used to decide when scheduled maintenance is due on the conveyor
and/or scale. The Master total can only be reset by the system
administrator at your facility, or by a Thermo Fisher Scientific
service technician.

 Reset Total

This total can be reset.

Performing an R-Cal For the First Time During Initialization

If you are performing an R-Cal for the first time as part of the Micro­Tech initialization process, make sure that the R-Cal error is less than

0.75%. (If the error is greater than 0.75%, there may be a problem. See
the manual’s the troubleshooting section on page 4-1 for additional
help.)

(The numbering below is continued from the previous page.)

6. Press the Yes button to set the span.

7. Press the Run button (in the display not the keypad) to return the

Micro-Tech to the Run mode. Congratulations! You are now ready
to put your Micro-Tech into operation.

Performing Any Subsequent R-Cal

Once you have initialized your Micro-Tech and are doing an R-Cal as
part of your weekly, daily, or other routing testing, proceed as follows.

In the example screen above, the display shows that the established span
is just 0.01% different from the previous span, meaning that both spans
are essentially the same and the scale is performing consistently. This
error is below the critical threshold error of 0.5% (or 0.25% for a Model
9201 integrator). As a result, the span should not be changed. Record the
span results for future reference.

However, if the error is greater than 0.5% (0.25% for Model 9201
integrator), there may be a problem—see the manual’s troubleshooting
section in the following chapter for additional help. Record the span
results for future reference.

Maintenance and Troubleshooting

The maintenance information in this manual should meet your service
needs. If problems occur requiring technical assistance, please call 1­800-445-3503 or the local Thermo contact listed in Chapter 5. Thermo
Scientific has a repair center located at our plant in Minneapolis,
Minnesota. Contact one of our technical representatives at
1-800-445-3503 for assistance or the local Thermo contact listed in
Chapter 5. To expedite your service request, please have your Micro­Tech model, serial number, and belt-scale code available.

The Micro-Tech Integrator is a solid-state device and should require
very little maintenance. The front panel can be wiped clean with a damp
cloth, and if necessary, a mild detergent (never use abrasive cleaners,
especially on the display window). As a preventative measure, check to
ensure all wires, plugs, and integrated circuits are tight in their
connectors. Also, keep the enclosure door tightly closed to prevent dirt
infiltration. More often than not, a quick visual inspection leads to the
source of trouble. If a problem develops, check the following before
proceeding to more specific troubleshooting procedures.

 Check Power

 Check the fuse.
 Check that the power switch is ON and that power is supplied to

the unit.

 Check Connections

 Check that all terminations are secure.
 Check to ensure the display, module, and keypad connectors are

firmly seated in their connectors.

 Check that all jumpers are in their correct position.

Frequently

Asked

Questions

Frequently Asked Questions

Here is a list of frequently-asked questions (FAQs) to help you resolve
common problems and concerns about operating, calibrating, and
maintaining your scale.

Question Answer

What is the best way to calibrate my
scale?

How often should the zero and span
be calibrated?

How often should I check the
mechanical installation of the scale?

The best way to calibrate your scale is to use the “Material Calibration”
method. (For details, see page B-13.) If, for whatever reason, you cannot
perform a Material Calibration on your scale, you can run a number of
“simulated-calibration” tests. For example, all Micro-Techs can be
calibrated using the “R-Cal” procedure, but y ou m ust have purchased the
optional equipment allowing you to run these simulated tests.

As a general rule, if you make or receive payment s based upon the weight
readings from your scale, the scale should be zeroed daily and the span
checked weekly.

• Your scale is only as good as the repeatability of your error on repeated
zero calibrations.

• The span should never change drastically, if the zero is properly
maintained.

If an external contractor is responsible for maintaining your scale, he or she
will establish an appropriate schedule for testing you r sc al e’s zero and
span.

The scale should only need daily preventive-maint enance checks for
material build up in critical areas, such as under the weigh idlers. The
exception to this is, when changes are made t o the scale area—for
example, when the belt or idlers are replaced. The s cale area includes not
only the weighbridge, but also the idlers that are shimmed with scale.

• A 10-20-1 scale system’s scale area includes +3 to -3 of scale.

• A 10-14-4 scale area includes +5 to –5. Any mai ntenance in this area

should be realigned, shimmed, and spaced to t he proper specifications.
If in doubt, please contact Thermo Fisher S cientific for the correct
specifications.

Why do I need to see repeatability
during calibrations?

Every time I complete a zero or span
test and get a percentage of error, do I
say “Yes” each time to change the
zero or span?

4-2 Micro-Tech 9101/9201 Reference Manual, R ev J Thermo Fisher Scientific

The repeatability of a scale is important f or the accuracy of the scale. If the
scale cannot repeat tests within the scale’s perc entage of accuracy, then
you should investigate why the scale is not repeating within the appropriate
tolerances.

The only time you should change zero or span is on the initial, start-up test.
Press the “Yes” button to change the span. In any subsequent test, even
when there is an error, press the “No” button—as any additional tests are
for repeatability, which is a maintenance feature of calibrations.

Load-Cell
Problems

Overview

Question Answer

Maintenance and Troubleshooting

Load-Cell Problems

Can I put a 100 lb. weight on the
weighbridge and see a reading of
100 lbs. in the Run screen?

What kind of information is available
from the digital output?

• Alarm cumulative

The short answer is “No,” because a weight is not a rate.

The signal delivered by the load cell or cells, which represents the weight
per unit length of the belt (lbs./ft), is multiplied by the signal delivered by the
speed sensor, which represents the belt speed (f t/min). The result of this
operation is the instantaneous flow rate (lbs./ft x ft/min = lbs./min), which is
then multiplied by a suitable constant to obtain t he value in the required
engineering units (kg/h, Tph, and so on). A n adj ust able damping filter is
provided separately for the displayed rat e and current outputs.

The programmable outputs are as follows.

• Shutdown cumulative

• Ready

• High load

• Low load

• High rate

• Low rate

• High speed

• Low speed

• Totalization pulse (remote

counter)

• Print ready

• Load weights

• Out of range

• Deviation alarms

This topic helps you solve problems with the load-cell circuitry, and is
divided into three sections that deal with the following components.
Please check which kind your particular system has before proceeding.

 Four-wire load cell—with no field sense leads.
 Four-wire load cell—with field sense leads.
 Six-wire load cell—with field sense leads.

A load-cell signal failure is usually caused by one of the following.

 Failed load cell
 Bad or incorrect wiring
 Failed A/D converter

Maintenance and Troubleshooting

Load-Cell Problems

The troubleshooting procedures detailed below consists of four simple
checks, as follows.

 Verify excitation/sense voltages.
 Verify proper sense jumper settings.
 Verify load cell mV signal at the Micro-Tech is within range.
 Verify load cell mV signal at the junction box is within range.

The Micro-Tech has a Diagnostics menu to help you troubleshoot the
load cells. Go to “Main Menu 3—Diagnostics.” Two menus pertain to
load-cell troubleshooting, as follows.

3 mV/V

2 mV/V

 A/D Gross and A/D Net (Diagnostic Scroll 1)

 Weight on Load Cell (Diagnostic Scroll 2)

This is a digital representation of the mV signal coming from the
load cell. The Micro-Tech maximum A/D is equal to 103,009 at 30
mV. Weight at the load cell can be calculated using either A/D
counts or mV input. Refer to the figure below.
