2.0 Installation
The MSI-4260 cast aluminum enclosure is rated at NEMA Type 4 IP 66. It hangs from a crane using properly sized shackles.
WARNING: 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 oversized
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 multiple lines to keep a single point attachment to the
scale.
IMPORTANT: Using an oversized 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 operates 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.
IMPORTANT: 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 flashes.
2.2.1 Battery Life
The battery life of the MSI-4260 depends on several factors:
• LED display brightness and number of segments lit
• RF activity
• Battery age
• SLA battery condition
The MSI-4260 includes the following power saving 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.
IMPORTANT: 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.

MSI-4260 Port-A-Weigh
12 Visit our website www.RiceLake.com
NOTE: 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 use before MSI-4260 powers off.
If the MSI-4260 is not going to be 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 depends on
the degree of battery discharge. A battery removed when the low battery warning first appears should take about four hours to
fully charge.
DANGER: Charger is for indoor use only and should not be used in wet locations.
NOTE: 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 also take significantly longer to charge.
Figure 2-1. Battery Charger Connected to Battery
The battery charger illuminates annunciators as the battery charges.To charge the battery:
1. Remove the battery from the MSI-4260 (Figure 2-2 on page 13).
2. Connect the charger assembly to the AC power supply (86-260 VAC). The power annunciator displays red.
NOTE: If the power status light fails to illuminate, check the AC power connection to ensure 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 all 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.
IMPORTANT: For maximum service life from batteries, the manufacturer suggests recharging after each 20 hours of use.
Continuous deep discharging reduces maximum battery life cycle.

2.4 Servicing
Rice Lake Weighing System’s dealer network provides both on-site and depot servicing of MSI-4260 crane scales. Please
contact a local dealer or Rice Lake Weighing Systems to obtain a return material authorization (RMA). Due to the weight and
size of many products, it is not always necessary to return the whole scale. Lower swivel hook assemblies and upper lifting
shackles on 50k capacity models and above do not need to be returned for service or recalibration. There are no user
serviceable parts inside the MSI-4260. Depot repair is performed with module and harness swaps. If the electronics are at fault,
often the front casting section is all that needs to be returned.

3.0 Operation
The following sections describe the Weigh mode operation of the MSI-4260.
3.1 Power
The power key turns the MSI-4260 power on. While in Weigh mode, it also turns the power off.
Press to turn on the power. The following sequence displays:
1. All LED segments light at full brightness as a display test.
2.  displays, followed by the software version number.
3.  followed by the weighing standard.
4.  displays, followed by the battery voltage.
5.  displays, followed by the display counting from 00000 to 99999.
6.  displays, followed by the C-CAL value.
7. MSI-4260 enters Weigh mode.
While in Weigh mode, press to turn off the power.
IMPORTANT: The scale has a maintenance battery drain. Always remove the battery if the scale will be off for an extended period
of time. Leaving a discharged battery in the scale can result in a deep discharged battery which will shorten its service life.
3.2 Zero
The zero key sets the zero reading of the scale.
Press to remove small deviations in zero when the scale is unloaded. For zeroing (taring) package or pallet weights,
see Section 3.3. The zero key can be used in GROSS or NET mode.
NOTE: The backup memory in the unit stores the zero reading and retains it even if the power fails.
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 stable window.
The unit will only zero if is on and there has been no activity 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 unit.
Example: If 100 lb on a 1,000 lb scale is zeroed, the overall capacity of the scale will reduce to 900 lb, plus the
allowed over-range amount.
3.3 Tare
Tare is used to zero out a known weight, such as a packing container or pallet, and display a NET weight. The TARE function is
defined as a Tare-In or Tare-Out operation.
To tare the scale:
1. Hang the empty container from the scale.
2. Press to enter a tare value. The MSI-4260 stores the current weight as a tare value and subtracts the value of
the container from the GROSS weight.  displays and the Weigh mode changes to NET.
3. Add the product to the packing container. The NET weight displays.
NOTE: To set a new tare, the existing tare must first be cleared. The MSI-4260 will not set a new tare over an old tare.

3.3.1 View Tare
To view the GROSS weight without clearing the tare value:
1. Program to the NET/GROSS function (Section 4.2 on page 21).
2. Press to toggle between NET and GROSS values. This will only work if a tare value has been established.
NOTE: The backup memory in the MSI-4260 stores the Tare reading and can restore it even if power fails.
Only positive GROSS weight readings can be tared. The STABLE annunciator must be on, 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. The RF Remote Control has NET/GROSS permanently available.
Example: Taring a 100 lb container on a 1,000 lb scale, the scale will overload at a NET weight of 900 lb (1,000-
100) plus any additional allowed overload (usually 4% or 9d).
3.3.2 Clear Tare
To clear a saved tare value, press . The GROSS weight displays.
NOTE: 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.
The scale stores the tare value in non-volatile memory and is restored when power is cycled.
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).
3.4 Function Key
