Operators ManualThe Digi-Star EZ 400 indicator is a highly reliable scale designed formobile weighing. This indicator can be connected to various load cellsystems.The EZ 400 has three standard methods of mounting the indicator plusthe optional RAM mount is available.Rail Mount (Included)Wedge Mount (Included)Wing Mount (Included)Ram Mount (Optional)Power can be obtained directly from a 12VDC battery or from a 120V or220V AC power cube that plugs into a wall outlet. Attach the powercable to the POWER connector located on the bottom panel of thescale.Connect the RED wire from the power cable to 12VDC and the BLACKwire to GROUND. The indicator is fused internally at two amps.Warning! Disconnect the indicator power cord before jumpstarting or fast charging a battery.Disconnect all indicator leads before welding onequipment. Damage may occur to the indicator andload cells.D3655-US1

The system is normallysupplied with a J-BOX cable going fromthe scale indicator to the load cell Jbox. Extension Kits are available fromyour dealer in various lengths. Toconnect the load cells, attach the J-boxcable to the LOAD CELL connector onthe bottom panel of the scale. Connectthe load cell cables to the J-box. Followcolor key on circuit board to insureproper connection of load cell wires.TerminalDescriptionWHITESIGNAL GREENSIGNAL -REDEXCITATION BLACKEXICTATION –SHIELDSHIELDIf connecting to load cells other than those that were provided with yoursystem, the indicator must be calibrated. Refer to calibrationprocedures (page 10-11) or contact your Digi-Star representative forassistance.Stationary systems should use “Lightning-Protected” J-boxes that allowyou to install ground rods. This provides protection to the scale whenlightning strikes nearby. Please call your Digi-Star representative torequest Form F3050.2

EZ 400#The Short Form Setup & Calibration procedure allows you to changethe “SETUP” and “CAL” numbers of the indicator. Setup and calibrationnumbers are displayed during the self-test.Do not attempt to calibrate the scale if the indicator is not reading stableweights. The calibration procedure will not fix instability, inconsistencies,or flashing "RANGE" messages.To run the self test with the indicator already ON:1. Press [Gross/Net} and then [On/Off] to start the Self Test.2. Press [On/Off] to "pause" the Self-Test while numbers aredisplayed.3. Press [On/Off] again to allow the self-test to complete normally.SETUP # CAL #SETUP NUMBERFollowing is a list of functions that are controlled by the “SETUP”number:Weigh Method (W MTHD)GainDisplay Units (LB-KG)Scale CapacityDisplay Counts (COUNT)The “CAL” number is adjusted to make the scale read the proper weightfor different load cells and to make accuracy adjustments on a scalesystem. Systems should be checked with known weights and adjustedif necessary to insure accuracy. Both the setup and calibrationnumbers are changed to convert a scale from lbs to kgs.#'Write down the current SETUP and CAL numbers of your EZ indicator.These numbers are displayed during the Self Test. . Press [On/Off] to"pause" the Self-Test while setup and calibration numbers aredisplayed. Press [On/Off] again, to "resume"SETUP # CAL #10

Operators ManualTo accurately calibrate the scale, you will need a large amount of weightthat has a known value. For best results you should have at least asmuch weight as the largest load you plan to weigh.1. Zero-Balance the scale so the display reads zero.2. Put the KNOWN WEIGHT on the scale platform and write downthe WEIGHT DISPLAY.Perform the following equation to find the ACCURATE CAL #.Example:The KNOWN WEIGHT is 2000lbs, but the WEIGHT DISPLAY is2080lbs. The EXISTING CAL # is 32500.2000 / 2080 X 32800 3153831538 is the ACCURATE CAL #. The setup number does not change.The Short Form Setup & Calibration procedure allows you to changethe “SETUP” and “CAL” numbers of the indicator.1. Press and hold [Zero], and then press [On/Off] for 3 seconds toenter the short form calibration.2. The display will flash “SETUP” and then display the 6-digitsetup number with the right digit flashing. To modify the setupnumber:3. Press [Gross/Net] several times to increment the digit to itproper value.4. Press [Tare] to advance the blinking digit to the left.5. Repeat steps 1 and 2 for each digit as required.6. Press [On/Off] to enter the new setup number and display thecalibration number.7. Repeat steps 1 and 2 to modify the calibration number.8. Press [On/Off] to enter the new calibration number and thedisplay will go back to normal.9. Verify the accuracy of the scale.D3655-US11

EZ 400#Select Weigh Method #1 for general weighing.() The General weigh method is an all-purpose weigh method for weighingdead loads. It is used for most applications.()%The Slow weigh method attempts to provide higher accuracy by filteringmany weight samples over a longer period of time. Small,instantaneous weight changes have less effect on the displayed weightusing this technique. This method is for weighing dead loads.()&The Fast weigh method is more sensitive to weight changes than theother weigh methods. When a weight changes quickly, the Fast methodtries to determine the new weight as quickly as possible. This is doneby providing less filtering during the actual "weight change." When theweight begins to stabilize, filtering is increased to provide an accurateweight display. This method is for weighing dead loads.*(()Set to “LOCKON” for animal weighing, this allows scale to weigh activeanimals and display an accurate weight that does not fluctuate. Set to“OFF” for weighing dead weights. Lock-On sensitivity can be adjustedusing the “LOCKON” menu.Once the actual weight is displayed, the scale “Locks-On” to thedisplayed. Weight does not change, even if the motion never stops. Asmall ‘L’ appears on the left side of the display indicating the weight is“Locked-On.” The “Locked-On” weight can be “rechecked” by pressing[Zero] on the front panel. This breaks the “lock” and the scalerecalculates the weight.NOTES:Setting the Weigh Method in the Long Form does not affectthe Display Unit LB-KG.In Weigh Method #1, #2 and #3 the ZTRACK (zerotracking) removes up to 0.05% of the scale capacity (asshown in setup). In Weigh Method #4 the weight that canbe removed is set to 5lbs(2.2kg).12

Operators Manual#"702#4 'The display shows the message "OVRCAP" if the weight on the scalesystem exceeds the capacity limit. The capacity value is entered inSETUP to warn of overloading the scale system. 0#%. The display shows the message " RANGE" if the weight on the scalesystem exceeds the maximum weight measurable by the scale system.The over range value is always the system’s maximum A/D countsmultiplied by the scaling factor. The actual weight at which over rangeoccurs depends on the calibration, zero, and display count size.0#%. The display shows the message "-RANGE" if the weight on the scalesystem is less than the minimum weight measurable by the scalesystem. The under range value is always the system’s minimum A/Dcounts multiplied by the scaling factor. The actual weight at which underrange occurs will depend on the; calibration, zero, and display countsize." #''If the supply voltage drops below the (10.5 Volts), the message“RECHARGE BATTERY - TURNING OFF” and “LO BAT” willperiodically show on the display to alert the operator of the low batterycondition.Warning! Disconnect the indicator power cord before jumpstarting or fast charging a battery.Disconnect all indicator leads before welding onequipment. Damage may occur to the indicator andload cells.Press [Gross/Net] then [On/Off] during normal system operation to startthe self-test.D3655-US13
