Load cart. 2. Press to begin unloading. Display reads Zero. Arrows point to Net and Unload. 3. Unload weight from cart. Display shows amount unloaded. 2 4 4 5 6 4. Press . after unloading is complete.
Operation Field ID 6 character identification value stored in internal memory of indicator to identify field being unloaded, truck being loaded or other information. 3 2 1 4 1. Press . FIELD is displayed and a flashing cursor or character is displayed in the first position. 2. Press to scroll available characters. Hold for 4 seconds to increase second scroll rate. 3. Press to scroll backwards through available characters. Press to move to the next character. 4. Press to accept and save.
Operation Print Formats Three print formats are available to output PRTACC value and FIELD ID to DDL or printer. PRTAC1: FIELD ID, 4856, GR, 274575, PA, 05FE08, I:44P PRTAC2: FIELD ID, 05FE08, I:44P 4856, GR, 274575, PA Includes following information: • Field ID • Weight • Weight Tag (NE, GR, Load/Unload) • Accumulated Weight • Print Accumulator Tag • Date and Time PRTAC3: FIELD3, 5977, LB, ,GR, 3097I9,PA,05FE08, 4:42P Includes above and adds “Unit of Measure”.
Operation Saving/Printing Gross Weights (Optional w/ Serial Option) 1. Press and hold three seconds to send weight to serial port. Each time this command is executed the value displayed is added to the “PRTACC” which is the accumulated weight. Weight is accumulated until cleared. 1 Turning Off the Indicator 1. Press until “BYE” is displayed.
Weighing Errors WEIGHING ERRORS Over-Capacity Limit (OVRCAP) The display shows the message "OVRCAP" if the weight on the scale system exceeds the capacity limit. The capacity value is entered in SETUP to warn of overloading the scale system. Over Range (+RANGE) The display shows the message "+RANGE" if the weight on the scale system exceeds the maximum weight measurable by the scale system. The over range value is always the system’s maximum A/D counts multiplied by the scaling factor.
MENUS AND CALIBRATION Menus and Calibration The Indicator has optional settings that allow flexibility in the way that the scale is used and data is collected. Changing Options Using Long Form Setup Enter Long Form Setup by holding and for three seconds. Press to advance to desired menu 1,2,3,4,CALIB, or EXIT, press to select. Press to advance to desired setting. Press to advance setting to desired option. Press to save setting option and advance to next setting.

SHORT FORM CALIBRATION Short Form Calibration The Short Form Setup & Calibration procedure allows you to change “SETUP” and “CAL” numbers of indicator. Do not attempt to calibrate scale if indicator is not reading stable weights. Calibration procedure will not fix instability, inconsistencies, or flashing "RANGE" messages. Obtain Current Set-up and Calibration Number Write down current SETUP and CAL numbers of your GT 400 indicator. These numbers are displayed during Self Test.
Short Form Calibration CALIBRATION NUMBER The “CAL” number is adjusted to make scale read proper weight for different load cells and to make accuracy adjustments on a scale system. Systems should be checked with known weights and adjusted if necessary to insure accuracy. Both setup and calibration numbers are changed to convert a scale from lbs to kgs. Calibrating Scale For Maximum Accuracy To accurately calibrate scale, you need a large amount of weight that has a known value.
Short Form Calibration Enter A New Setup And Calibration Number 1 4 3 1 1. Press and hold and for 3 seconds to enter short form calibration. 2. The display will flash “SETUP” and then display the 6-digit setup number with the right digit flashing. 3. Press several times to increment digit to it proper value. 4. Press to advance digit left. Repeat steps 3 and 4 for each digit as required. 6 5 5. Press to enter new setup number and display calibration number.

Troubleshooting TROUBLESHOOTING FLOW CHART START YES Is the reading on the Indicator stable? Does the indicator come on? If your display is unstable, or flashes “±RANGE” disconnect the j-box cord from Indicator. Is display still unstable? NO YES Put your weight on each NO load cell. Does the indicator respond to your weight? Check all J-Box and Load Cell YES cables for cuts or pinched/flat spots. Are the readings all positive? If not Load Cell is upside down. Does the scale weigh you approx.
FLOW CHART Continued 1. Disconnect all the Load Cell wires from the terminal blocks inside the J-Box (leave the Indicator on while connecting and disconnecting the wires, it will not damage Load Cells or Indicator if wires are shorted during this step). Is reading on Indicator stable? YES Hook up the Load Cells to the J-Box one at a time (only one Load Cell connected at a time). This will get a reading for each Load Cell.
