  • Page 33 This function changes the scale to a filling machine which sub-divides a bulk product,e.g. grain, into loads of predetermined and virtually constant mass. It is necessary to set the parameter of the “comparator function ( f6 9 )”, “ full/dribble batch sub-function ( f10 0 ~ f10 3 )”...
  • Page 34 Caution The comparison of the full/dribble batch function is not reversible (One way se- quence). If the display value becomes less than the final value after the value reached a predetermined target value, neither HI or LO is on. The parameters of the upper limit value (HI) and the final value (HI) use the same memory.
  • Page 35 Step 1 Turn off the display. Press the switch while the switch ON/OFF ZERO is pressed and held. The function table is displayed. Step 2 Press the switch to display an item of ENTER the comparator function ( f6 ). Step 3 Select a parameter of the full/dribble batch function ( f6 9 ) with the ^ switch.

  • Page 37 This function compares a display value with the final value, preliminary value and zero band for the full/dribble batch function. The result is indicated to zero band (LO indicator), full flow (HI indicator) and dribble flow (OK indicator). Even if a weighing value increases and decreases this function continues to compare.
  • Page 38 Caution The parameters of the upper limit value (HI) and a final value (HI) use the same memory. The parameters of the lower limit value (LO) and the zero band (LO) use the same memory. The upper/lower comparator function, the simple batch function and the full/dribble batch function cannot be used at the same time because these parameters use common memory.
