During a short The 3, 4 and 5 modules will be bypassed if the output options period of time the digits, the decimal point and LEDs will turn are not installed. The information related to its programming on as a verification of the correct function of the instrument.
  • Page 13 The programming instructions are composed by a general description and a series of step-by-step instructions to be followed sequentially. Each menu step is represented by an illustration of the display and keyboard module with indicators (display and LED's), reference [page number. figure number] and a text describing the action of each key at that step. [Page nº/figure nº] Mnemo In the step-by-step instructions, you are given the action of the three buttons mainly used to program data.

  • Page 14: Input Configuration

    2.3 - INPUT CONFIGURATION Fig. 14.1: excitation jumper To completely configure the input of the load-cell indicator, it will be necessary to act on these two parameters: 1. Excitation voltage selection. The indicator provides two excitation voltages to supply the transducer; 5 V or 10 V. The selection is made by means of a plug-in jumper located behind the input card connector.
  • Page 15 3. Input programming range. The only configurable parameter is the input range. There are four available ranges; 15 mV, 30 mV, 60 mV or 300 mV which are to be chosen to match the cell sensitivity (max. output in mV). The maximum voltage applicable to the instrument is 300 mV. The built-in excitation voltage can be used to power up to 4 cells connected in parallel, with 10 V excitation and up to 8 cells with 5 V excitation.

  • Page 16: Display Configuration

    2.4 - DISPLAY CONFIGURATION Fig. 16.1: Linearizing After selection of the input range, it may be necessary to (inp7, dsp7) function with 6 scale the instrument for the particular application. For many (inp6, dsp6) segments (7 points). common applications, single slope scaling (2 points) should (inp5, dsp5) (inp4, dsp4) be sufficient to have good readings over the entire process...
  • Page 17 3. Scaling the indicator. After deciding the values for INPUT and DISPLAY and the decimal point position, we are ready to enter in the display configuration module. It has six configurable menus: scaling, balanced filter, damping filter, round filter, tare and sensor break detection.
  • Page 18 MENU 2A - SCALE This menu allows programming the necessary parameters to determine the display range (INP1 - DSP1 - Decimal Point - INP2 - DSP2 - INP3 - DSP3 -…). As a default, these values are expected to be introduced by keyboard. To use the actual signal input values as INP# parameters, it is sufficient to push on the key at INPUT programming phases.
  • Page 19 [19.1] Decimal point Programming the decimal point which apears blinking. Press repeatedly the key to move it to the right until desired position. Si If no decimal point is required, it must be placed to the right side of the display. The PROG decimal point remains in the selected position in all programming phases and the run mode.

  • Page 23 MENU 2B - BALANCED FILTER The balanced filter acts as a delay on the display response to signal variations produced at the input. The filtering level is programmable from 0 to 9. The effect of incrementing this filter level results in a softer response of the display to the input variations.
  • Page 24 MENU 2AB - DAMPING FILTER The damping filter cuts off input values exceeding from the limits of a symmetrical band. This band becomes more selective as the filter level is increased. The filtering level is programmable from 0 to 9. Level 0 disables the filter. [24.1] Damping filter The figure 24.1 shows the indication (FLt-E) corresponding to entry stage of the damping filter menu.
  • Page 25 MENU 2AB - ROUND FILTER This menu allows selection among 4 levels of display rounding. When resolution is not critical, a rounding increment higher than 1, may help to stabilize the display. [25.1] Round filter The figure 25.1 shows the indication (round) corresponding to the round menu. Press to access the configurations ENTER PROG...
  • Page 26 MENU 2 – MODE TARE In this menu you can configure the mode TARE [26.1] Mode TARE The figure 26.1 displays the text (ModtA) that corresponds to the menu that allows the selection of the mode TARE. Press key to access this menu. PROG ENTER Access the configuration.
  • Page 27 With the key we select the tare processing mode of the instrument. When you access this menu, the stored tare value is reset to zero and as always that the instrument is in this state, the Tare LED will be turned off. Once selected the run mode, we exit to the run mode where the tare process will be done.

  • Page 29 MENU 2 – SENSOR BREAK This function allows detecting any broken wire that connects the sensor “Load Cell” to the instrument. The analysis to detect the broken wires is done every 1.5 seconds and the response of Relays and ANA options (if used) will be the same if it were a overflow (oVFLo) situation, input signal greater than allowed.
