SECTION 1 – INTRODUCTION & INSTALLATION
INTRODUCTION
The Measurement Systems International MSI-9300 Series Porta-Weigh Plus Crane Scales are designed to
provide a rugged weight indicator and data system for any type and size of crane used in industry. Two basic
styles are available: MSI-9300 and MSI-9300HT. This guide is used for both versions as they have identical
electronics.
The standard MSI-9300 is supplied with rotating hooks or shackle interfaces. The MSI-9300HT Hi-Torque
version features a fixed load train that does not rotate and a new load cell design that withstands the induced
torque associated with power assisted rotating loads. With options available for both top and bottom inter-
faces, the MSI-9300HT easily integrates with existing powered rotators to provide safe material handling and
increased operational efficiency. The MSI-9300 Series combines CellScale technology with MSI’s advanced
Crane Scale architecture providing both a local and remote display capability. Combined with CellScale acces-
sory components, they become advanced data gathering networks suitable for process control, safety monitor-
ing, and weight related data collection.

overhead weighing system for use indoors and out. The large 1.2” (30mm)
ultra bright LED readable at distances up to 50’ (15m). Display bright-
ness can be set to automatically adjust to ambient lighting conditions for
optimum viewing and battery conservation.
The MSI-9300 Series crane scales can communicate with CellScale family
indicators and modems at distances up to 1000’ (300m) outdoors (even
further with gain antennas). Both fixed and handheld indicators are avail-
able, as well as Modems for direct connection to computers. A remote
4-20mA interface is available for direct connection to PLCs and other
process control equipment. CellScale Virtual Monitor (CVM) software is
available to enable your PC to act as a full-featured digital scale indicator
with data logging capabilities.
INSTALLATION
The MSI-9300 installs easily by hanging it on the crane, using properly
sized shackles. Follow proper loading procedures to ensure that side load-
ing is eliminated. Please refer to MSI’s brochure, “Crane Safety” when
installing model MSI-9300.
One of the most common installation problems is using an oversize

it has reached its end of life.
shackle or too large a hook to interface with the MSI-9300. This can cause off center loading and stress points
that will reduce the life of the MSI-9300 lifting eye or hook. Use the appropriate interface hardware for the
capacity of the scale. If your interface hardware does not fi t properly, MSI can supply the MSI-9300 with
oversize lifting eyes or shackle interfaces. If the crane hook is too large to fi t in the lifting eye with single point
interface, then install the scale using adaptive rigging.
If multiple attachments are needed, use a shackle or ring to attach the multiple lines to thus keeping a single
point attachment to the scale. Single point attachments are necessary to ensure the safety and accuracy of the
scale system.
Regular maintenance inspections of the lifting system should be performed to ensure safety. Pay particular
attention for signs of stress on any element in the load train.
BATTERY REMOVAL & REPLACEMENT
1) Turn the crane scale Off.
2) With one hand, hold the battery access to prevent it from falling.
3) Rotate the two cam-latch knobs counter-clockwise until the plate latches disengage.
4) Carefully back the plate out of the battery well.
5) Release the battery retaining strap.

6) Remove the battery by pulling straight back.
7) Install a fully charged battery by plugging it in to the exposed battery jacks. The crane scale will turn on
briefly then turn itself off.
8) Reattach the battery retaining strap.
9) Reseat the access panel.
10) Put pressure on the plate to partly compress the gasket. While applying pressure, turn the cam-latch knobs
clockwise until the plate is reseated. Make sure the plate is firmly in place.
BATTERY LIFE
The MSI-9300 battery life depends on a number of factors: Brightness of the LED and number of segments lit,
the amount of RF activity, and the age and condition of the SLA (sealed lead acid) battery. The MSI-9300 will
automatically turn the scale off when the SLA battery drops to approximately 10.5V. You must recharge the
battery when this happens. Leaving a discharged battery in the scale, which has a maintenance battery drain,
can result in a deep discharged battery which will shorten its service life.
SLA batteries do not suffer from memory effects and actually benefit from frequent rechargings. Recharge
the battery whenever it is convenient even when it still has available life. Due to the maintenance discharge
imposed on the battery by the MSI-9300 electronics, do not store the MSI-9300 more than 7 days with the
battery inside. Remove the battery.
Battery Use Guidelines
1) Recharge whenever convenient. Do not wait for the scale to shut itself off if your work situation permits.
2) If you need the scale continuously, keep a fully charged spare battery. Replace the drained battery as close
as possible to the low battery warning, or earlier.
3) SLA Batteries that have not been deep discharged should withstand 500 to 1500 charging cycles.
4) The low battery warning will indicate about 2-4 hours of additional use before the MSI-9300 turns itself
off.
5) If the MSI-9300 is not going to used again soon, remove the SLA battery to prevent deep discharge while
the unit is in storage.
BATTERY CHARGER
Each MSI-9300 Series crane scale is shipped with a battery charger (MSI P/N 502221-0001) designed to
charge and maintain the battery. Exact charging time will depend on the degree of discharge of the battery. A
battery removed when the low battery warning first appears should take about 4-6 hours to fully charge. A deep
discharged battery might take 24 hours to recover.
Using the Charger
1) Remove the Battery from the 9300. See previous page for removal instructions.
2) Connect the charger assembly to the AC supply (86-260VAC). The Power Status light should be green. If
the power status light fails to illuminate, check your AC power connection and make sure the VAC jack is
fully seated.
3) Plug in the polarized connector to the jacks on the battery.
4) The Charge Status light should turn ORANGE indicating fast charge.
If the status light remains Green when the battery is first plugged in, the battery may be defective.
5) Charge until the status light turns GREEN.
Deep discharged batteries may require a couple days to recover full charge.
When the charge cycle is complete you can (and should) leave the battery on the charger until it is needed. The
charger keeps a maintenance float charge on the battery to ensure the best possible operation times. For scales
that are in high usage, MSI recommends obtaining a spare battery so one can always be on the charger.

1) POWER – Push to turn the scale on or off.
2) ZERO – Used to zero the scale. The zero range is usually 100% of full scale unless prohibited by legal-for
trade settings.
3) NET/GROSS – Switches scale between NET and GROSS weight readings (assuming a Tare value has
been stored).
4) TARE – When in GROSS mode, pushing TARE will zero any weight on the scale and cause the scale to go
into the NET mode. When in NET mode, pushing TARE will display the TARE value for 2 seconds, then
revert back to the NET weight display. In NET mode, pushing TARE twice will set a new Tare. Pushing
TARE followed immediately by ZERO will clear the Tare value and revert the scale to Gross Mode
5) TEST/USER Key – When pushed, this causes a display segment check, and provides battery and RF
Network information. Also programmable for USER desired functions. See SETUP USER KEY. User Key

1) Push POWER. The system performs a display
check: All segments and annuciators illuminate
for 3 seconds.
2) The LED displays the firmware Rev number.
3) Next, the display shows the Network address
followed by the ID address. This is the operat-
ing network address for any slave device to log
onto.
The network and ID Address are usually but not always the
same. Numbers for Network range from 0 to 31 and for address
from 0-254. Initially the MSI-9300 display will not know the Net-
work address and will skip this step.
4) The display begins a numeric test while the
CellScale component is establishing Network
and Comm Port connections. The count up pat-
tern will continue for 10-20 seconds and will
sometimes restart. This is normal.
5) Once the RF Network is established and the
Comm Port connection to the display is set the
display will indicate “ConEct” [sic]. The scale is
now ready for operation.
MULTIPLE SCALE CHANNELS
MSI-9300 Series crane scales are capable of hosting multiple independent scale inputs. These are connected
via RF using MSI-6260CS and/or MSI-9300 Series crane scales setup as Network Slaves, or by special order,
additional inputs can be hard-wired directly. In addition, the CellScale Math channels can be used for manipu-
lating the scale data. To directly access additional channels, the TEST/USER key can be programmed to “S
List” to scroll through the available scale channels. See “USER KEY FUNCTION” in this manual. See the
CellScale User Guide for the procedure to add additional channels. The crane scale’s keypad operates on the
displayed channel only.
ZERO
Sets the zero reading of the scale. Use the zero key to take out small deviations in zero when the scale is
unloaded. (See “TARE” for zeroing (Taring) package or pallet weights)
To Zero
Push ZERO. The weight reading must be stable within
±1 division for the zero function to work.
The backup memory stores the zero reading, and can restore it even if
power fails.
The numeric digits display “0” (or 0.0 or 0.00, etc.).
0
ZERO
0.0
Rules for Use:
1) Works in GROSS mode or NET mode. Zeroing while in Net mode will zero the gross weight causing the
display to show the negative Tare value.
2) The scale must be stable. The scale will not zero if the motion detect annunciator is on.
3) The scale will accept a zero setting over the full Range of the scale (NTEP and other Legal-for-trade
models may have a limited zero range). Zero settings above 4% of full scale will subtract from the overall
capacity of the scale. For example if you zero out 100 lb. on a 1000 lb. scale the overall capacity of the
scale will reduce to 900 lb. plus the allowed over-range amount.

TARE
Tare is typically used to zero out a known weight such as a packing container or pallet and display the load in
NET weight. A Tare value is entered in one of three ways:
1) AUTO TARE – When the TARE key is pushed twice, the current weight is zeroed and Net Weight is dis-
played. This is the only Tare function available from the MSI-9300 keypad.
2) KEYBOARD TARE – Available from a 3750CS or 9750A Indicator only. Using the numeric keys, the
operator keys in the desired Tare Weight then pushes the ENTER Key. See the 3750CS or 9750A User
Guides.
3) TARE UP/DOWN – Available from a 3750CS Indicator only. Using the Scroll Keys, the Tare value is
changed one scale division at a time. TARE UP/DOWN is useful for increasing or decreasing the cur-
rent Tare value slightly. The Keyboard Tare and Tare Up/Down modes can be disabled through the use
of SETUP TARE. In the “AUTO” mode a single push of the TARE key will enact AUTO TARE. See the
3750CS User Guide.
To Auto Tare (in Gross Mode)

Page 10 MSI-9300 Crane Scale™ • User Guide
MSI-9300 Porta-Weigh+ Crane Scale
Tare - Rules for Use:
1) Only positive gross weight readings can be tared. Weight can be tared in both the NET and GROSS
modes. When in the NET mode, the TARE is not cumulative, all the weight is zeroed.
2) The motion annunciator must be off. The weight reading must be stable.
3) Setting or changing the tare has no effect on the Gross zero setting.
4) Taring will reduce the apparent over range of the scale. For example, taring a 10 lb. container on a 60
lb. scale, the scale will overload at a net weight of 50 lb. (60-10) plus any additional allowed overload
(usually ~4% or 9d).
5) The scale stores the Tare value in the current ID Code memory until cleared. Each available ID Code
can store independent Tare values.
Multiple Tare Memories
MSI-9300 Series crane scales are capable of storing Tare values through the use of the ID Codes. Each ID code
stores an independent Tare. ID Codes are accessible through the MSI-3750CS, MSI-9750A or MSI-9850, or
through a MSI-9020 CellModem using Host Commands.
SPECIAL TARE MODES
The Tare function has two special modes. These modes are configured through the Comm Port. See the MSI-
9000 CellScale User Manual for information on configuring the Tare Mode.
UNIV TAR
The Universal Tare feature allows a single Tare value to be shared by all ID Codes. With UNIV TAR enabled
the individual Tares stored with each ID Code are ignored (but not erased). Disabling UNIV TAR will restore
the original Tare values. UNIV TAR is intended for those applications where a common carrier or pallet is
used, but multiple ID Codes are necessary for data collection.
AUTO CLR
Enabling “AUTO CLR” causes the MSI-9300 to clear the Tare Value after each lift greater than 0 NET. The
Tare Value is cleared and the display mode reverts to Gross Weight once the load is removed (the weight goes
below 0 NET). The “ON TOTAL” setting clears the Tare Value after the load is totaled. The default for the
“AUTO CLR” function is “DISABLED” . When disabled, the Tare Value can only be cleared manually (see
“To Clear Tare and return to Gross Mode”.)
NET/GROSS
Switches the display between Net and Gross modes. Net Weight is defined as Gross Weight minus a Tare
Weight.
To Switch Between Net Mode and Gross Mode
Switching back to Gross mode from Net mode will not clear the Tare value. This allows the operator to use the Gross Mode temporarily without having to rees-
tablish the Tare value. Only manually clearing the Tare or setting a new Tare will change the tare value held before switching into Gross Mode.
OIML Legal-for-trade units only: The NET/GROSS key is temporary action only. The Gross weight is displayed for 2 seconds and then the display
returns to the Net Mode. The only way to return to permanent Gross readings is to clear the Tare (see Clear Tare procedure).

2) Pushing NET/GROSS again will revert the display to the
NET mode.
UNITS

INTERNAL TEMPERATURE DISPLAY
The MSI-9300 can monitor its internal temperature. This feature is for use in Foundry applications or any other
Crane use around high temperature sources. The temperature display can be set to display automatically at 20
second intervals (see page 15) and will display in degrees C or degrees F. The purpose of monitoring the inter-
nal temperature is to ensure that the scale is not damaged by overlong exposure to high temperatures. The MSI-
9300 offers a heat shield option for foundry use that increases the dwell time possible when lifting melt pots.
MSI-9300 Series Crane Scales must be immediately removed from the high heat source when the inter-
nal temperature reaches 158°F or 70°C.

When the scale is used in multiple RF Networks, the RF List function allows the user to easily switch between
several networks. These networks must be setup in the embedded CellScale (See MSI-9000 User Guide).t
This operation requires that the Test/User Key function is set to RFList. See “Setup USER key Function ”.

TOTAL
The MSI-9300 CellScale feature set provides Total and Statistics capabilities. The MSI-9300 keypad allows the
enabling and display of some of these features. More extensive total and statistics capability is provided when
a 9750A or 3750CS meter is part of the network. However, the MSI-9300 allows the setting of the following
Total features:
1) OFF – Total feature turned off
2) Autoload – The autoload feature provides an algorithm for totaling that requires a 3750CS equipped with
an auxiliary push button. Intended for commodity loading into containers. See the CellScale User Guide
for a complete description of the Autoload feature.
3) Autonorm – The Autonorm Total will automatically total all steady weights above the auto total threshold.
Once totaled, the weight must return to near zero before the scale will autototal again. The autonorm
total totals the last settled weight before the scale went back to zero, so be sure the weight is removed
rapidly from the scale.
4) Autopeak – Similar to Autonorm except the weight totaled will be the highest settled weight before the
weight returns to near zero.
5) Press – Indicates that a manual total key must be pressed to cause a total to occur. This can be the USER
key programmed to total, or total keys found on the 3750CS or 9750A indicators.

To Change Current RF Network
This feature is intended for use in large installations where, for service or work load purposes, the crane scale
must be used on a new network. When the crane scale is a remote (slave) device, the Master CellScale must be
configured with a matching channel 5 scanlist to allow seamless Network migration. In other words, the “MY
ID” must be identical to the unit it is replacing. Make sure two remote devices with the same “My ID” are
never on at the same time in the same Network.
When the crane scale is a Host (Master) device, only the network number can be changed, the master “My ID”
will not change. All remote devices on the previous network will lose communciation.

SECTION 4 – RF REMOTE CONTROL
DESCRIPTION
MSI-9300 Series crane scales can be equipped with an RF Remote Control (RFRC). This differs from using
the MSI-9750A or MSI-3750CS Indicators to control the scale. The RFRC is a transmit only device that can be
used to perform basic scale functions. It does not have the range of the Spread Spectrum modems built into the
RF versions of MSI-9300 Series crane scales and is intended for local control only. Range will vary from 25’ to
100’ depending on room conditions and line of sight to the display. The remote receiving antenna is behind the
red lens of the crane scale and best range will occur when the display is visible to the operator using the RFRC.
One big advantage the RFRC provides is the ability to turn the unit on remotely. The RFRC can also be used in
systems that do not have the RF Modem.
The RFRC is available in three versions differing only in transmit frequency. The standard version operates at
418MHz. Available alternative frequencies are 315MHz and 433MHz.

FUNCTIONS
The RF Remote control duplicates the functions of the front panel keys on
MSI-9300 Series crane scales. The POWER, ZERO, NET/GROSS, and TARE
key function identically. In addition, the RFRC adds direct control of TOTAL
and VIEW TOTAL without the use of the USER key. The TOTAL still needs to
be enabled and configured in the embedded CellScale before these features will
function properly. See page 14 for the procedure to set up the Total mode.
The F1 key functions the same as the TEST/USER key on the front panel. The
exact function of this key depends on the USER key setup procedure. See page
12 for the procedure to configure the USER key which will also configure the
F1 key on the remote. Since the RFRC has a dedicated key for Total, there is no
need to program the USER key to Total, and it can be used for other purposes.
The F2 key is programmed to trigger a remote print. When F2 is pressed, the
crane scale will transmit the data string programmed in the virtual Comm Port
3 of the embedded CellScale. This data string can be used in a variety of ways.
For example, a remote printer can be connected to the MSI-9020 CellModem.
When F2 is pressed, the remote printer could print the weight along with time,
date, total weight, or any other data parameter available from the embedded
CellScale. Another common use is to send the weight data to a computer config-
ured to data log the information to a database.
For information on Data Strings and the use of Virtual CommPort 3, refer to the
MSI-9000 CellScale Users Guide. F3 and F4 are not supported by MSI-9300
Series crane scales. These keys function as TOTAL and VIEW TOTAL (∑).
SETTING THE TRANSMITTER ADDRESS
In order to allow the formation of up to 1024 unique
Transmitter-Receiver relationships, the transmitter’s
address may be selected using internal DIP switches as
shown. The switches are accessed by removing the DIP-
switch access cover.
If the switch is on, the address line is connected to ground, otherwise it is float-
ing. The receiver’s address must match in order for the units to communicate.
MSI supplies the transmitter and receiver as a matched
set with the DIP switches already configured. A replace-
ment RFRC will only need to have the transmitter DIP
switch set. To change the DIP switch in the receiver
requires disassembly of the crane scale front casting.
Due to differing DIP switch styles, the receiver DIP switch appears opposite to that
of the transmitter. On the receiver, the OFF position is on the right, and the ON
position is on the left.

CONTENTION CONSIDERATIONS
It is important to understand that only one transmitter at a time can be activated within a reception area. While
the transmitted signal consists of encoded digital data, only one carrier of any frequency can occupy airspace
without contention at any given time.

SECTION 4 – THE EMBEDDED CELLSCALE
For a complete guide to all the features of the embedded CellScale, refer to the MSI-9000 User Guide.
ACCESSING THE CELLSCALE
MSI-9300 Series crane scales are a shell interface to an embedded CellScale. To access the advanced features
of the CellScale, a Comm Port is provided on the front casting of the crane scale. This Comm Port is only used
for interfacing to the embedded CellScale and cannot be used as an output of any kind.
The CellScale offers Set Points, ID Codes, and other advanced features which are controlled either through a
remote Indicators such as the MSI-3750CS, the MSI-9850, or the MSI-9750A Handheld. These features are
also accessed by connecting a terminal program in a PC to the Comm Port. Tested terminal programs that
function well with the CellScale include ProComm Plus, Qmodem, HyperTerm (shipped with many versions
of Windows), WinTerm, and ZTerm (for Macintosh). Usually a VT102 emulation is used. All commands are
single key except when entering data.
Settings for your terminal program are: 9600 baud, 8 bit, 1 start bit, 1 stop bit, no parity, Handshaking usually
not required, but you can turn on Xon/Xoff if you desire.
While the Comm Port is in use, the display of the MSI-9300 Series crane scale is in standby with the message
“C-Port” or “H-Port” displayed. The only key that will function in this mode is the Power key.
The CellScale Terminal Access Mode is used to set Network parameters, Scale parameters, Set Points, and
other various setup conditions. Refer to the MSI-9000 CellScale User Guide for detailed information. The Ter-
minal Access Mode is used for calibration on MSI-9300 Series crane scales that do not have the RF modem.
CONNECTION PROCEDURE
The MSI-9300 must be on and finished with its startup sequence before connecting the
terminal cable to a PC.
1) Without connecting the PC or Terminal to the MSI-9300, turn the MSI-9300 on. Wait for the startup
sequence to complete (usually about 10-15 seconds). When weight is displayed, the MSI-9300 is ready.
2) Press and Hold the NET/GROSS key and then push TEST. The display should change to “H-PORT”.
3) Connect the PC to the MSI-9300 through the Comm Port. Start your terminal emulation program with set-
tings 9600-N-8-1
4) You can now access the Terminal menus in the CellScale. Push any key to refresh the menu.
5) Once in the Terminal Access Mode menus, commands are usually a single number or letter. Refer to the
9000 CellScale User Guide for further information.
COMM PORT CABLE
The MSI-9300 comes standard with one Comm port cable wired for RS-232 (MSI P/N 501705-0001) follow-
ing the AT standard for 9 pin serial cables (DCE). An unterminated cable is available (MSI P/N 12023) if you
wish to wire your own serial cable for RS-232.
