Technical Manual

3-2

The ‘Parameter Set-up’ menu contain the following sub menus:

General:

This parameter group controls the general functionality of the instrument.

Such as display language, display mode, security, key functions and so on.

Hardware Configuration:

Parameters used for configuring the instrument hardware.

Note that when the instrument is starting up it will check that the installed hardware is
compatible with the settings. If not an alarm will be issued.

Calibration:

Parameters that affect the behavior of the eight possible weighing

channels (scales) in the instrument. There are parameters for calibration type,
calibration values, no of transducers, filter settings, motion detection, zero handling and
so on. All weighing channels are individually settable.

Communication:

Sub menus are Serial Com, Ethernet and Fieldbus.

Serial Com sub menu content are parameters used to set-up COM1 (RS232) and
COM2 (RS485) on the CPU module. Parameters are among others: com. port mode,
baud rate and data format. Ethernet sub menu content is parameters for Modbus TCP
Slave and External I/O configuration. Fieldbus sub menu content is configuration
parameters related to fieldbus communication such as address, baud rate and
transmitted data setup.

Level Supervision:

The instrument has 32 level supervisors that are configured from

this sub menu. Settings for each level are which scale (measuring channel) that the
individual level is to monitor, which signal that shall be monitored from the selected
scale. Signals that can be monitored are gross weight, net weight, flow rate and so on.
The output function e.g. if the output shall be active above or below the set level is
configured here. The fourth parameter for each level is the hystereses setting.

Setpoints:

The G4 instrument contains 16 setpoints that are individually configurable

regarding which scale it shall be connected to and which signal it shall monitor.

Inputs:

The use of the instruments digital inputs is set in this menu. Note that the

inputs are numbered 11 to 68. Inputs 11 to 18 corresponds to inputs on slot 1 I/O
module, 21 to 28 correspond to inputs on slot 2 I/O and so on. Note that the actual
number of inputs depends on what type of I/O-module that is installed in the respective
slots. A DIO8 module has 8 inputs a WF IN2 module has 4 inputs while an AOUT1 or
AOUT4 has no inputs. Possible usage for an input is tare command, zero command,
gross/net toggling and so on. Certain commands like taring is scale oriented and a
second parameter for each input is used to set which scale it shall work with.

Outputs:

The outputs menu contains the settings controlling the function of each

output. Numbering is 11 to 68 for the I/O module outputs. See section ‘Inputs’ above on
how individual output numbers correspond to each I/O slot. Each output can be
assigned an output function: Level output status, setpoint output status, net mode,
good zero, stable weight, flow rate displayed or In process status. All functions needs a
second parameter that sets which level, setpoint or scale the output is supposed to
work with.

Analog Outputs:

This menu controls the behavior of an AOUT4 or an AOUT1 Analog

output module. The output signal source (scale no and signal type) can be selected.
Also output type and range high/low is settable. The Analog Outputs menu is only
shown if there is an AOUT1 or AOUT4 used in the system.
