    Weighing equipment (Optional equipment) Calibrating the weighing equipment The “Zero calibration” function is used to increase the accuracy of the weighing equipment. This should be done once a month. See the section headed “Zero calibration” under “Machine operation”. If a new scale unit is installed, it must be calibrated as described in the section ”Calibrate the scale”...

    Weighing equipment (Optional equipment) To replace a load cell • Machines without tilt function: Remove nut + bolt (A). • Use a suitable jack to lift under the frame at the corner where the load cell is to be replaced. • Insert a suitable object as a chock beneath the frame, to remove risk of injury and machine damage.

  • Page 178: To Replace The Scale Unit

    • Take the scale unit off its mounting plate. • Install the new scale unit, assembly in reverse order of disassembly. • Check that the dead load selector is set to 1000-1400 kg for W4400H, 2100-2550 kg for W850H, W1100H and 1200-1600 kg for W600H.

  • Page 183 Fault-finding procedure: • Check that the dead load selector is set correctly. It should be set to 1000-1400 kg for W4400H, 2100-2550 kg for W850H, W1100H and 1200-1600 kg for W600H. • If you are or have recently been calibrating the weighing equipment, the calibration switch may be incorrectly set, or an incorrect calibration weight may have been used for calibration.
  • Page 184 Weighing equipment (Optional equipment) Information in display: Function not allowed. Probable cause: A function has been selected in the program which cannot be carried out. Fault-finding procedure: • Check that the function in question is switched on under “Settings”. • Check that the cables for CPU communication, power supply and load cells are connected.
