M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L INTRODUCTION The MSI-4260 Port-A-Weigh is an electronic, self-contained, battery-operated crane scale. The scale is made up of three separate sections which house the electronics, load cell and battery respectively. The sections are bolted together and sealed agaist moisture by the use of O-Rings. The scale housing is made of impact resistant, marine grade 356 alloy.
M E A S U R E M Set Points: E N T S Y S T E M S I N T E R N A T I O N A Two internal standard Set Points and two ultra-bright LEDs on indicator panel Service Counter: Two independent 24 bit registers; Register 1 updated each time weight exceeds 25% of capacity; Register 2 updated each time weight exceeds overload; when register 1 exceeds 99,999 or register 2 exceeds 1000, display reads "LCnt" for load cell counter; Test function shows the two readings in order Connectors:
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L The LED display provides excellent readability from full sunlight to total darkness. In the event of an overload condition, the display will flash a warning to the operator.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L BATTERY PACK The Port-A-Weigh is powered by a 12 volt rechargeable battery. The battery is located in the rear compartment of the scale. Two stainless steel fasteners secure the battery access door. To remove the battery for charging; unlatch the fasteners and pull the battery straight out. The battery will automatically disengage from its connectors and may be plugged into the battery charger for recharging.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L to the maintenance discharge imposed on the battery by the MSI-4260 electronics, do not store the MSI-4260 away with the battery inside. Remove the battery if the MSI-4260 will not be used for more than 2 weeks. Battery Use Guidelines 1) Recharge whenever convenient. Do not wait for the scale to shut itself off if your work situation permits.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L The charger is a universal input type and is rated for 100-240VAC, 50-60Hz. AC power cords suitible for any world location are available from MSI. BATTERY REMOVAL AND REPLACEMENT 1) 2) 3) 4) 5) 6) 7) 8) Turn the MSI-4260 off. With one hand, hold the battery access cover. Release the two latches holding the access cover. Carefully lower the cover and when possible, hold the battery in place.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A Use 1) The battery pack must have enough charge to ensure accurate operation (>10.5V). 2) Ambient temperature must be greater than -10°C and less than 60°C (14°F to 140°F). Action 1) Press [POWER] and hold for one second. 2) Display check: All segment and indicator LED’s are illuminated for one second. 3) Numerics display the software version number for one second.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L 5) Only positive weight readings can be tared. 6) Setting or changing TARE has no effect on the ZERO setting. 7) Tareing will reduce the apparent overrange of the scale. For example, if a 1000 lb container is tared and the scale capacity is 5000 lb, the scale will overload at a new weight of 4000 lb (5000 - 1000) plus any additional allowed overload (usually 9 divisions).
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L played for 3 seconds. 4) The CAL number is displayed next. To ensure that the CAL number is accurate, the scale must be unloaded. Cal number shifts of up to 10 counts are insignificant. 5) All digits (7 segment and 16 segment) count once from 0 to 9. All indicators are tested. 6) Internal tests are performed to further ensure scale integrity.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L RESET THE SERVICE COUNTER WARNING 1) After inspecting the load train, remove the calibration seal screw. 2) Push the Calibration button using a blunt screwdriver. 3) Push [ZERO] to return to normal operation. Note: This procedure does not reset the service counter. TOTAL (totAL) Function For accumulation of multiple weighments.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L Use 1) When a weight threshold of 2% of Full Scale (FS) above NET ZERO or GROSS ZERO is exceeded, the accumulate function operates automatically. 2) When a weight that meets the minimum acceptable limit settles (no Motion), the TOTAL indicator will flash 3 times. 3) If the weight changes to a new settled value the TOTAL indicator will flash again indicating the previous settled reading has been replaced.
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A L 2) The display reads "0" and the TOTAL indicator will illuminate for 2 seconds. Final After clearing the TOTAL, normal weighing resumes. VIEWING TOTAL Function After a weight has been totaled or before the 1% threshold has been exceeded, the current TOTAL can be Viewed. Action 1) Make sure there is no load on the scale. Press [F1] (Function button must be programmed as TOTAL).
M E A S U R E M E N T S Y S T E M S I N T E R N A T I O N A Final 1) When enabled, the PEAK (Phold) value is reset to 0 and any subsequent displayed value will correspond to the greatest positive weight detected. 2) When PEAK(Phold) is disabled the scale will perform normally. NET/GROSS (nEtGr) Function Switches the display between NET and GROSS Modes. NET Weight is defined as GROSS Weight minus a TARE Weight.
