    G4, which makes it easy to integrate the instrument into industrial processes. G4, type RM, is easily mounted on a DIN rail. All connections and the service panel are accessible from the front end. By a LCD-display and four function keys at the service panel, weight values are presented and parameter values can be viewed and edited.

  • Page 6: Start-Up

    Operating instructions, Quick installation Start-up As soon as power is connected to the instrument, it will display 'Vishay' during a start-up period, then the text ‘Start up, please wait’ is displayed after some seconds. Then G4 automatically switches to normal measuring operation.

  • Page 9: Operation

    G4 Multi Channel Weighing Instrument Operation Zero indication and zero adjustment A basic zero setting of the gross weight for unloaded scale is performed at installation as a part of the calibration. When a ‘good zero’ is displayed, the letter ‘Z’ is shown under the measurement value.

  • Page 10: Taring

    This makes the additional function 'Tare' available for the scale. But the scale can also be set to allow taring only at stable weight (letter 'M' not shown). In G4 two tare values can be stored, Auto tare and Preset tare. Auto tare By taring, the actual gross weight is stored as Auto tare value, and the scale will switch to display of net weight 'zero'.

  • Page 11: Editing Preset Tare

    G4 Multi Channel Weighing Instrument Editing Preset tare In this example Scale 1 is set for taring with ‘Preset tare’. The example shows editing the value of ‘Preset tare’ from VIEWPAN. Scale 1, set for preset taring, 033.2 kg is in normal weighing operation.

  • Page 12: Weight Printing

    Weight Printing A printer can be used to print the displayed weight or the displayed flow rate. The printer must be connected to one of the G4 Instrument serial communication ports and the communication parameters must be correctly set. This example shows how to make a print out of the displayed weight for Scale 1 (the displayed scale) from VIEWPAN.

  • Page 13: Level Supervision

    G4 Multi Channel Weighing Instrument Level supervision With G4 it is possible to supervise different weighing signals at defined levels. The instrument contains 32 supervising units, Level 1 to Level 32, which can be connected to the scales by the parameter set-up.

  • Page 14: Accumulated Weights

    Operating instructions, Quick installation Accumulated Weights Every time a weight is printed the weight value is added to an accumulated value for each scale. Accumulation is done even if no printer is set-up or connected. Accumulated weights can be changed and set to zero from menu 'Accum. Weights'. This menu is reached from the 'Main Menu'.

  • Page 16: Flow Display (Program Option)

    Operating instructions, Quick installation Flow display (program option) When option Flow display is activated for a scale, the additional function 'W/F' can be shown in the scale display. When 'W/F' is made visible during weight display, and key ↵ is pressed, this will switch the scale over to display of flow value.

  • Page 17: Scale Batching (Program Option)

    G4 Multi Channel Weighing Instrument Scale Batching (program option) The RM instrument is a complete multi scale batcher but it is not intended as an operator interface for batching. It is possible to set-up the batching sequences from the RM instrument front panel. However for control (start, stop, reset etc) of the batching sequence should a supervising computer be used (PLC, SCADA system etc).

  • Page 32: Data Sheet Calibration

    Operating instructions, Quick installation Data sheet calibration This calibration method can be used when data sheets for the transducers are available and no external forces influence the weighing installation. If fixed supports are included, the load must be evenly distributed on all supports. Data sheet calibration can be performed without any transducers connected, but the transducers must be connected as the zero setting is performed.
  • Page 33 G4 Multi Channel Weighing Instrument 1:Rated Load Rated load for the transducer is a value, given in the data sheet. All the transducers in the scale must have the same impedance and rated load. The rated load value, expressed in the unit of the data sheet, should be entered for this parameter.
