1.5 Features • Designed to meet or exceed applicable US and international safety standards. • Up to 100 hours of weighing time utilizing Automatic Sleep Mode. • Automatic Power Off conserves battery life by sensing no activity after 15, 30, 45 or 60 minutes, determined by operator, and turns off power. • Automatic sleep Mode preserves battery life by dimming the LED display after 5, 15, or 30 minutes of no activity. • Rugged construction throughout.
1.8 Installation The MSI-4260 features a heavy duty, cast aluminum enclosure rated at NEMA 4 IP 66. It installs easily by hanging it on the crane, using properly sized shackles. Please refer to MSI’s brochure, “Crane Safety” when installing Note model MSI-4260. One of the most common installation problems is using an oversize shackle or too large a hook to interface with the MSI-4260. This can cause off center loading and stress points that will reduce the life of the lifting eye or hook.
1.9 Battery Pack The MSI-4260 is powered by a 12 volt Sealed Lead Acid rechargeable battery. The battery will operate for up to 100 hours (depending on LED brightness setting) before requiring recharging. In order to conserve battery life, the scale includes an Automatic Power Off Mode which senses operational status for no activity after 15, 30, 45, or 60 minutes, and turns the scale off. An additional battery saving feature is the Automatic Sleep Mode.
1.9.3 Battery Charger Each 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 4 hours to fully charge. Note When the battery is new, it might take significantly longer for the initial charge. MSI recommends charging a new battery for 24 hours.
1.9.4 Battery Removal & Replacement 1. Turn the MSI-4260 Off. 2. With one hand, hold the battery access cover. 3. Release the two latches holding the battery access cover. Remove the latch by pressing in on the spring catch, and pull on the latch lever. 4. Carefully lower the cover and when possible, hold the battery in place. The battery might be loose and subject to falling. 5. Remove the battery by pulling straight back. 6. Install a fully charged battery by plugging it in to the exposed battery jacks.
1.10 Comm Port The MSI-4260 has a single Comm Port allowing access to the embedded ScaleCore through the Terminal Access Mode or MSI Software. The Terminal Access Mode is used for updating scale firmware while MSI Software can be used for calibration and configuration, backup and adjusting scale settings. This Comm Port is not intended for output use as it is usually impractical to use a cable connected port on a Crane Scale. 1.10.
1.11 Servicing the MSI-4260 MSI’s Dealer Network provides both on-site and depot servicing of MSI-4260 Crane Scales. Please contact your local dealer. MSI also operates a service center for all our products. Contact MSI Service at 1-206-433-0199 to obtain an RMA (returned material authorization). Due to the weight and size of many of our products, it is not always necessary to return the whole scale. If the electronics are at fault, you can often return just the front casting section. See Figure 1-5.
1.12 RF Connectivity The MSI-4260 has several options for RF Connectivity: 1. 802.15.4 – Standards based DSSS (Direct Sequence Spread Spectrum) connection at 2.4 GHz This is used for connectivity to MSI’s Model 8000 hand held remote display. It can also be used with a 802.15.4 modem to connect to scoreboards or computers. 2. 802.11b,g,n – Standards based DSSS WiFi connection at 2.4 GHz. For operation on an 802.11 Access Point to Ethernet networks.
2.0 Operation 2.1 Power To turn on the power. POWER 1. Press , the following will display in order: • LED will light all segments at full brightness as a display test. • Display brightness will change to the setting determined in the Display Menu. • Software version number will display. • The MSI-4260 is ready for use. es 2.2 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 Section 2.
2.3 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 by pressing the TARE key. The TARE function in the MSI-4260 is defined as a Tare-In, Tare-Out operation. The first press of the TARE key 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.
3.0 User Defined Function Keys The following function descriptions are for optional user defined functions that are programmed on the front panel USER key or the two function keys (F1 & F2) on the RF Remote Control. The functions TOTAL, VIEW TOTAL, and NET/GROSS are available full time on the RF Remote Control. To enable any of the USER key functions, you must set up the USER keys following the procedures in Section 4.0.
Weight is <1% of Capacity – The USER key functions as “View Total” only and functions as View Total until the 1% threshold is exceeded to allow the next addition to the total value. AUTO TOTAL The USER key under the AUTO TOTAL mode functions as Auto Total On / Auto Total Off. The Auto Mode has three variations which are programmed in the SETUP menu: • AutoLoad – Any settled weight above the ‘Rise above’ threshold will be automatically totaled.
LEARN Used for programming the RF Remote Control. This function is detailed in Section 6.0. PEAK HOLD Peak Hold will only update the display when a higher peak weight reading is established. The Peak Hold function uses a high speed mode of the A/D converter allowing it to capture transient weights at a far higher rate than typical scales. Peak hold is cleared and re-enabled with the USER key. PEAK HOLD is not available on NTEP or OIML LFT certified scales.
4.0 Set Up 4.
4.2 Function Keys The MSI-4260 has 1 user definable function key on the Front Panel, and an additional user definable function Function key on the RF Remote Control that can be programmed to any of several functions. Function Key Setup 1) With the 4260 off, press and hold the USER key, then press the POWER key. ...or while the 4260 is on, press USER and POWER simultaneously. Hold POWER USER F esc 2) The first item of the Setup Menu is “Func1”. USER 3) To setup the User key press TARE.
4.3 Auto- Off The Auto-Off feature, when enabled, prolongs the battery life of the scale by turning POWER off when the scale is not in use. Any time a button is depressed (any button), or the detected weight is in Motion exceeding 5 or 10d, the time limit is reset. Therefore, the scale will stay on indefinitely if the weight is changing or any button is pressed at least once. With Auto-Off disabled, the scale will remain on; only pressing POWER will turn it off (or if the battery is depleted).
4.4 Sleep The SLEEP feature reduces power consumption by automatically turning off the display during periods of inactivity. While in the Sleep Mode, the Green Acknowledge annunciator will blink at a 1s rate to indicate the MSI-4260 is in sleep mode. To wake up either a button must be pushed (front panel or RF remote), or the weight must change by 5 d or more. Note SLEEP must be set to less time than the Auto-Off timer. For example, set SLEEP to five minutes and Auto-Off to 30 minutes.
4.5 Display Brightness The Display Setup menu is used to set the display brightness. There are four fixed brightness settings and one automatic light sensing brightness setting. Auto setting will automatically detect the ambient light and adjust the brightness of the display accordingly. Bright light will cause the display to be at the brightest setting. The display brightness will reduce as ambient light reduces.
4.6 Set Points The MSI-4260 supports three set points. Common uses of set points are for warnings or process control. The MSI-4260 comes standard with LED outputs for a triggered set point. Set Point 1 is Blue, Set Point 2 is Green and Set Point 3 is Red. The MSI4260 has an audible output option that is triggered by Set Point 1. Contact MSI for other Set Point Output Options. Set Point Setup 1) With the 4260 Off, press and hold the USER key, then press the POWERkey. ...
Set Point Setup (continued) To enter a decimal point, push POWER while the digit is blinking. Error Correction: If you input a wrong value, press ZERO to step back one digit and change the digit with the USER key. Number value entry continued 9) When the desired number is shown, push TARE a second time to set the value. The next Setup Menu item is displayed. 10)Either press ZERO to exit Setup and store all changes, or continue to another Setup Menu item using the USER Key.
4.7 Total Mode The MSI-4260 can keep track of all weighments using the Total feature. Either manual total, which totals by pushing a configured USER key on the front panel or the RF Remote, or Auto-Total, which can be used to automatically add up each weighment. See the Total mode descriptions for details on the various Total modes. To use Manual Total, you must also program a User Key.
4.8 Units Units can be changed in two ways: • Program a User Function Key to Units • Change the units with the setup menu with the following procedure Note The OIML LFT scales do not allow units to be changed. Units Setup 1) With the 4260 off, press and hold the USER key, then press the POWER key. Hold USER F POWER esc ...or while the 4260 is on, press USER and POWER simultaneously. USER )YQF 3) To setup the weight units, press TARE. The display will blink “Unit”.
4.9 Filter Setup Changing the filter settings allows the scale to adjust to situations where there is a lot a movement in the structure. If the reading is not stable, it can often be improved by increasing the filter setting. Settling time will be longer as the filter setting is increased. However, the MSI-4260 employs algorithms that speed up large weight changes while still controlling vibration even with high filter settings.
5.0 Calibration The MSI-4260 is calibrated using standard weights. It is required that the weight used is at least 10% of full capacity in order to achieve rated accuracy. For example, use at least a 500kg test weight to calibrate a 5000kg capacity scale. Although a single span point is usually adequate for rated accuracy, the MSI-4260 supports Multi-Point calibration with up to 4 span points + Zero.
p 8) To enter a calibration weight other than capacity, press USER. The display far left digit will flash zero indicating that a number should be entered. 9) Press the USER key to scroll the number and the TARE key to enter each digit of the calibration weight. In this example, we’ll enter 2500 kg on a 5000 kg capacity scale. Do not push theTARE key two times in a row until the entire number is showing.. To add a decimal point, push the POWER key while the number is blinking.
14) The display now reads “LoAd3” or “LoAd4”. Repeat steps 12 and 13 for additional span points press TARE or press ZERO if you are finished. /RDG or To enter another span point TARE T /RDG After LoAD4 has passed, the 4260 will automatically advance to the next step. 15) The display shows “CAL’d” to indicate that the calibration was successful. 16) Press TARE. The display flashes “C-CAL” followed by the C-CAL number. &$/ G TARE T Flashing Make a note of this number.
5.1 Initial Calibration Use this procedure only if the capacity and count-by (d) needs to be modified. The initial steps of the initial calibration will totally erase user setups as well as any previous calibration. Cal Switch Access Initial Calibration Resetting Capacity and Countby (d) 1) Turn the 4260 off. Remove Hex Seal Screw 2) Remove the seal screw. With a small screwdriver press and hold the CAL Switch behind the seal screw.
14) The first digit blinks. Use the USER key to scroll through the numbers. When the desired number is shown, push TARE. In this example, we’ll enter 2500 as a capacity. Continue inputing the desired capacity using the USER key for scrolling the number and the TARE key to store the number. 15) Finalize the capacity value by pressing the TARE key on an unblinking display. In our example, once the number 2500 is fixed on the display, press TARE to store the capacity value.
Due to LFT requirements and general scale design criteria, the weight must be stable for certain features to work: ZERO – Weight must be stable to be Zeroed. TARE – Weight must be stable to be Tared. TOTAL – Weight must be stable to be added to the total registers. One way to improve the stability is to increase the filtering, at the risk of increasing settling time. The other is to increase the ‘d’ (reduce resolution). The third way is to increase the “Motion Window”.

6.0 RF Remote Control Option 6.1 Description 6.2 Functions Scale Remote Controller ZERO F1 F2 TARE NET GROSS TOTAL F3 F4 Measurement Systems International MSI-4260 Series RF Indicators can be equipped with an RF Remote Control (RFRC). The RFRC is a transmit only device that can be used to perform basic scale functions. The default switch functions can be changed in the Function Key menus and used for any MSI-4260 programmable functions.
6.3 Setting the Transmitter Address The MSI RF Remote Control Transmitter allows the selection of one of 16,777,216 (2 24) unique addresses. All transmitters are supplied set to the same address. To MODE_IN avoid contention with other units or to create unique relationships, the address window should be changed. This is accomplished by using a paper clip or probe to press the CREATE button on the board through the hole in the back of the case. 1.
6.5 Contention and Jamming 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. This is not to say that you cannot have multiple remote controls for the MSI4260, but rather that you can’t use two simultaneously.
6.7 RF Remote Control FCC Statement Instruction to the User: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
7.0 RF Remote Display Option 7.1 Introduction The MSI-4260 can communicate with peripheral devices using RS-232, 802.15.4, or 802.11/b,g,n WiFi. Only one communications type can exist at a time. Due to the difficulty of dangling RS-232 cables from a hanging crane scale, the RF options are more commonly used for gathering weight data. The RS-232 port located on the right side of the MSI-4260 is useful for setup and calibration using a computer and MSI’s SCCMP Software.
7.3 Printer / Serial Output Setup The RS-232 Comm Port is capable of outputting tension data. All the weight modes the RF linked weight device can measure are available in user formatted form. The Control Mode programs what causes the MSI-4260 to print. The modes are: 1) When an assigned F-Key is pressed, one transmission of the selected string type is output. 2) On Load – When the tension on the link is stable, one transmission will output.
