2.0 Installation
The MSI-4260 features a heavy duty, cast aluminum enclosure rated at NEMA Type 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 batteries, store 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 SLA battery.
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.
*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.
*Low battery warning annunciator indicates about two to four hours of additional use before MSI-4260 powers off.
*If MSI-4260 is not going to used again soon, remove SLA battery to prevent deep discharge while 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. A battery removed when the low battery warning first appears should take about four
hours to fully charge.
Charger is for indoor use only and should not be used in wet locations.
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 illuminates annunciators as the battery charges.
1. Remove the battery from the MSI-4260 (Figure 2-2 on page 7).
2. Connect the charger assembly to the AC power supply (86-260 VAC). The power annunciator displays red.
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. Charging annunciators illuminate to represent charge
percentage.
4. Charge until the all of the status annunciators fully illuminate.
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.
For maximum service life from 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 menu, drops back one menu level. At the root menu level, the stores the changes
and returns to the weight mode.
• When in Setup menu, returns directly to the Weight Display without storing the changes.
• When in Setup menu, functions as the scroll key.
• When in Setup menu, 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 displays
• The MSI-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
• Works in GROSS 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 4% 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.
A Tare 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 displays.
• 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 ~4% or 9d).
The scale stores the tare value in non-volatile memory and is restored when power is cycled.
