2.0 Installation
The MSI-4260 features a heavy duty, cast aluminum enclosure rated at NEMAType 4 IP 66. It installs easily by
hanging it on a crane using properly sized shackles.
Refer to the Crane Scale Safety and Periodic Maintenance Manual (PN 153105) for safe loading and
rigging guidelines when installing the model MSI-4260.
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.
Use the appropriate interface hardware for the capacity of the scale.
•If the interface hardware does not fit properly, Rice Lake Weighing Systems can supply the MSI-4260 with
oversize lifting eyes or shackle interfaces.
•If the crane hook is too large to fit 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 keep a single point
attachment to the scale.
Using an oversize shackle or hook to interface with the MSI-4260 can cause off center loading and stress
points that will reduce the life of the lifting eye or hook.
Single point attachments are necessary to ensure the safety and accuracy of the scale system.
2.1 Unpacking
When unpacking the MSI-4260, ensure that all assembly parts are accounted for. Check the MSI-4260 for any
visible damage. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper
immediately. If the MSI-4260 must be returned, it must be properly packed with sufficient packing materials.
Whenever possible, use the original carton when shipping the unit back.
2.2 Battery Pack
The MSI-4260 is powered by a 12V Sealed Lead Acid (SLA) rechargeable battery. This battery will operate for up
to 100 hours (depending on LED brightness setting) before requiring recharging.
Charging time for a completely discharged battery is up to eight hours. A spare battery pack is recommended to
keep the MSI-4260 in continuous operation.
To obtain maximum service life from the batteries they should be stored between -4°F and 122°F (-20°C
and +50°C). Stored batteries should be recharged every three months. The battery is fully charged when
the status indicator on the battery charger is flashing.
2.2.1 Battery Life
The battery life of the MSI-4260 depends on a number of factors:
•The brightness of the LED display and number of segments lit
•The amount of RF activity
•The age of the battery
•The condition of the SLAbattery.
In order to conserve battery life, the MSI-4260 includes the following features.
•Automatic Power Off Mode — senses no activity after the set amount of minutes and turns the scale off.
•Automatic Sleep Mode — dims the display after a set amount of minutes of no scale activity.
The MSI-4260 automatically turns off when the SLA battery drops to approximately 10.5V. Recharge the battery
when this happens, SLA batteries benefit from frequent recharging and can be recharged when it still has available
life.
Due to the maintenance discharge imposed on the battery by the MSI-4260 electronics, do not store the MSI-4260
with the battery inside. Remove the battery if it will not be used for more than two weeks.
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.
WARNING

6MSI-4260 Port-A-Weigh Crane Scale
• If the scale is in continuous use, a fully charged spare battery is recommended. Replace the drained battery as close as
possible to the low battery warning.
• SLA batteries that have not been deep discharged should withstand 500 to 1500 charging cycles.
• The low battery warning annunciator will indicate about two to four hours of additional use before the MSI-4260 turns
itself off.
• If the MSI-4260 is not going to used again soon, remove the SLA battery to prevent deep discharge while the unit is in storage.
• Recycle the battery at an authorized recycling center when the average life drops to 20 hours or less.
2.2.2 Battery Charger
The MSI-4260 is shipped with a battery charger designed to charge and maintain the battery. Exact charging time
will depend on the degree of discharge of the battery. Abattery removed when the low battery warning first appears
should take about four hours to fully charge.
When the battery is new, it might take significantly longer for the initial charge. It is recommended to charge a
new battery for 24 hours. It might take several charge/discharge cycles before full capacity is reached. Deep
discharged batteries will also take significantly longer to charge.
Figure 2-1. Battery Charger Connected to Battery
The battery charger is a universal input type that is a three-stage float charger that can be left on the battery
indefinitely. It is rated for 100-240VAC, 50-60Hz. It has a dual color LED to indicate the charging state.
•Red – charge mode.
•Green – top off mode.
•Blue – Float (fully charged) mode
If the status light remains green when the battery is first plugged in, the battery may be defective. Use the following
steps to charge a battery.
1. Remove the battery from the MSI-4260. See Figure 2-2 on page 7.
2. Connect the charger assembly to theAC power supply (86-260VAC). The charge indicator light should be green.
If the power status light fails to illuminate, check the AC power connection to ensure the V in the jack is fully
seated. AC power cords suitable for any world location are available from Rice Lake Weighing Systems.
3. Plug the polarized connector into the jacks on the battery.
4. The charge status light should turn RED indicating fast charge.
5. Charge until the status light turns GREEN. This indicates the charger is in top off mode. The battery has
sufficient charge for use. The charger and battery are in float charge mode when the charge indicator turns
BLUE.
When the charge cycle is complete, the battery can be left on the charger until it is needed. The charger keeps a
maintenance float charge on the battery to ensure the best possible operation times.
To obtain maximum service life from the batteries, the manufacturer suggests recharging after each 20
hours of use. Continuous deep discharging reduces maximum battery life cycle estimated at 2000 cycles.

3.0 Operation
The following sections describe the basic operation of the MSI-4260.
3.1 Navigation of Menus
• If a function key does not work, it is probably because the MSI-4260 is not set up to support the key. For
example, if the Function Key is set for TOTAL, the TOTAL mode must also be set up in the Setup Menu.
• When in Setup menus, drops back one menu level. At the root menu level, the stores the
changes and returns to the weight mode.
• When in Setup menus, returns directly to the Weight Display without storing the changes.
• When in Setup menus, functions as the scroll key.
• When in Setup menus, functions as the ENTER/SELECT key.
3.2 Power
To turn on the power, press . The following will display in order:
• The LEDs will light all segments at full brightness as a display test.
• Display brightness will change to the setting determined in the Display Menu.
• The software version number will display.
•TheMSI-4260 is ready for use.
3.3 Zero
The zero key sets the zero reading of the scale. Press to take out small deviations in zero when the scale is
unloaded. See Section 3.4 on page 11 for zeroing (taring) a package or pallet weights.
The scale digits display 0 (or 0.0 or 0.00, etc).
The backup memory in the MSI-4260 stores the zero reading and retains it even if the power fails.
Rules for Use:
•WorksinGROSS or NET mode.
• Zeroing while in net mode will zero the gross weight causing the display to show a negative tare value.
• The scale must be stable within the motion window. The scale will not zero if the stabilizer annunciator
is off. The scale will remember that it has a zero request for two seconds. If a motion ceases within the
motion window in that time, the scale will zero.
• 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 four percent of full scale will subtract from
the overall capacity of the scale.
Example: If 100 lb on a 1000 lb scale is zeroed, the overall capacity of the scale will reduce to 900 lb,
plus the allowed over-range amount.

3.4 Tare
Tare is used to zero out a known weight such as a packing container or pallet and display the load in NET weight.
ATare value is entered by pressing . The TARE function is defined as a Tare-In, Tare-Out operation.
The first press of stores the current weight as a tare value and then the scale subtracts the tare value from the
gross weight and changes the display to NET mode. The next press of will clear the Tare value and revert
the display to GROSS mode.
To view the Gross weight without clearing the Tare Value, program to the function NET/GROSS.
The RF Remote Control has a Net/Gross permanently available.
To tare and display the net weight, press .
The weight reading must be stable within the motion window for the tare function to work.
The scale digits display 0 (or 0.0 or 0.00, etc) and the weight mode changes to NET.
The backup memory in the MSI-4260 stores the Tare reading and can restore it even if power fails.
To clear the tare and revert to gross weight, press . GROSS will display.
•Only positive gross weight readings can be tared.
•The must be off indicating weight reading is stable.
•Setting or changing the tare has no effect on the gross zero setting.
•Taring will reduce the apparent over range of the scale.
Example: Taring a 100 lb container on a 1000 lb scale, the scale will overload at a net weight of 900 lb
(1000-100) plus any additional allowed overload (usually ~four percent or 9d).
•The scale stores the tare value in non-volatile memory and is restored when power is cycled.
