  • Page 6: Scale Annunciators

    Fig. 1: Model 4300 Front Panel Layout The operational controls for the Model 4300 consist of the ZERO, PRINT, UNITS, OVER and UNDER buttons. A six digit LED display is used to display weight and operator messages during scale operation. Three lights, above the LED display indicate checkweighing status.

  • Page 7: Power Up

    Under illuminates to indicate weight is below the Under target and above the Low target or flashes if below the Low target. Accept illuminates to indicate weight is at or above the Under target and at or below the Over target. Over illuminates to indicate weight is above the Over target and below the High target or flashes if above the High target.

  • Page 8: Over

    OVER OVER allows entry of the upper checkweighing limits. It is also used to increment a checkweighing value that is being modified. UNDER UNDER allows entry of the lower checkweighing limits. It is also used to decrement a checkweighing value that is being modified.

  • Page 9: Battery Operation

    Battery Operation The 4300 can be optionally configured with a self-contained Rechargeable Sealed Lead-Acid battery and charging circuit, both internal. The scale is designed to run continuously for up to 60 hours with a single 350 ohm load cell. To maximize battery life, leave the auto-off timer enabled which will automatically power down the scale after a period of non-use.

  • Page 10: Three Band Checkweighing

    Three Band Checkweighing Three band checkweighing classifies weighments into over, accept and under. The 4300 defaults to three band checkweighing. Note that lb:oz is not supported for checkweighing limits. Three Band Checkweighing 1. Remove all items from the scale platform 2.

  • Page 11: Five Band Checkweighing

    Five Band Checkweighing Five band checkweighing classifies weighments into high, over, accept, under and low. See three band checkweighing to set over and under checkweigh limits. The C.o. parameter must be set for five band checkweighing to enable this capability. Note that lb:oz is not supported for checkweighing limits.

  • Page 12: Weight Reference Entry Of High And Low Limits

    Weight Reference Entry of High and Low Limits 1. Press ZERO 2. Place an item of the desired weight on the scale platform 3. Press and hold the OVER or UNDER until the display reads High or louu respectively 4. The display will briefly read over or under followed by the weight on the platform and checkweigh status annunciators will flash 5.

  • Page 13: Zero Band Checkweighing

    Zero Band Checkweighing Basic checkweighing - simply set the desired weight on the platform, press zero and checkweigh based upon the standard tolerances in the O.U. parameter. Zero Band Checkweighing 1. Remove all items from the scale platform 2. Place the target weight on the scale platform 3.

  • Page 14: Installation Guide

    Installation Guide Fig. 2: Motherboard Layout Removing and Replacing the Rear Panel Before you remove the rear panel, remove AC power. Power down the scale if the optional battery power is present. Removing the rear panel requires a 5/16” nut driver. To replace the rear panel and achieve a tight seal, each screw requires a rubber bonded washer and the gasket needs to be in place.

    Load Cell Connection Load cell connections are made through terminal block TB1. The power cord connects to terminal block TB5 adjacent to the transformer. Fig. 3: Load Cell and Power (lower left of board) 4 wire load cell 6 wire load cell J1 Jumper J2 Jumper Load Cell Input (TB1)

  • Page 16: Power Connection And Fuse

    Power Connection and Fuse Power input is located at terminal block TB5, next to the fuse and black transformer. Neutral Ground Line (Hot) Make sure power is off before replacing the fuse. The scale's fuse (F1) is located next to the power terminal (J1). The scale has a filtered power supply to reduce the effects of normal line noise, but it cannot limit severe fluctuations.
