    G4, which makes it easy to integrate the instrument into industrial processes. The front panel of G4, types PM/DT/HE, is flat, dustproof, and waterproof. It has a back lighted graphical colour LCD display with touch sensitive screen for weight information, set-up information and error messages.

  • Page 6: Maintenance

    The instrument may only be utilized for the measurement and control functions, described in the Technical Manual for G4 Multi Channel Weighing Instrument, PM/DT/HE types. It is especially important to adhere to the load limits of the input/output connectors.

    If an error occurs this will be indicated by an error code at the display. Info key The Info key at the upper right corner of the panel is used to enter G4 menu system. Function keys Just below the display there are five function keys, marked F1 to F5.

  • Page 8: Display Alternatives

    Operating instructions, Quick installation Display alternatives It is possible to configure G4 to display one, two or four scales at a time, or a combination of the mentioned views. If a combination of views is used, the arrow keys 'right' and 'left' are used to select a display alternative. Only configured scales will be shown.

  • 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 text ‘Zero’ is shown to the right in the display.

  • Page 10: Net Weight

    But the scale can also be set to allow taring only at stable weight (when the text ‘Motion’ is not shown). In G4 two tare values can be used: 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’.

    G4 Multi Channel Weighing Instrument Editing Preset tare In this example Scale 1 is set for taring with 2006-09-24 19:07 ‘Preset tare’, and for displaying the value of the ‘Preset Tare’ at Info Line 1 Scale: 1 Gross 034.5 kg (and Scale Name at Info Line 2).

  • Page 12: Level Supervision

    Operating instructions, Quick installation 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. For each scale up to 4 connected Levels are indicated at the display in normal operation.

  • Page 28: 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 29 G4 Multi Channel Weighing Instrument 1:Rated Load Rated load for the transducer is a value, given in Edit: 1:Rated Load the data sheet. All the transducers in the scale must have the same impedance and rated load. Value: 2000.00 The rated load value, expressed in the unit of the data sheet, should be entered for this parameter.

Calibration parameter(s) changed! Do you want to keep the new settings? Answer Yes to keep the new settings in the instrument memory, Cancel answer No to exit calibration without saving (all changes will be rejected).

  • Page 31: Deadweight Calibration

    G4 Multi Channel Weighing Instrument Deadweight calibration This is the most accurate calibration method. It requires that known weights to at least two-thirds of the scale capacity are available. A deadweight calibration of a scale should start with the scale parameters, described on page 22.
  • Page 32 Operating instructions, Quick installation 1:Value Cal. P2 This parameter, in a two point calibration, defines Edit: 1:Value Cal. P2* the load for the highest calibration point. Normally the scale should be loaded to at least two-thirds Value: 100.0 of the scale capacity. This weight value and the corresponding transducer signal value are automatically stored for the scale.

  • Page 34: Zeroing Of Gross Weight

    Operating instructions, Quick installation Zeroing of gross weight When the scale installation is calibrated, a zeroing is performed in order to get the gross weight zero when the scale is unloaded. If mechanical equipment is added later, this will affect the weight display for the scale, and a new zeroing of the gross weight becomes necessary.
