G4 Multi Channel Weighing Instrument
Basic set-up
General
All operating functions in G4 are controlled by parameters, stored in the instrument
memory. The actual setting of the parameter values can be edited during normal
weighing operation, by the display and the keys on the service panel VIEWPAN.
WARNING. Changes done during editing of set-up parameters will affect the
behaviour of the instrument immediately. The user must take all necessary
precautions to prevent any undesired effects in process monitored or controlled
by the G4 instrument or a connected control system.
It is strongly recommended to activate the set-up lock in the instrument to prevent
any unauthorized changes of set-up parameters.
This section proposes a number of parameters to set, that will rapidly give
the instrument a useful presentation mode and basic measuring properties.
It contains setting of, for example, the measurement unit and resolution for
the weight value, and also some parameter settings for data sheet calibration
and deadweight calibration in two points.
If you are dealing with an already working instrument we recommend that you perform
a backup of the set-up parameters before you make any changes to the instrument.
When the set-up is finished, all parameter values should be noted (see appendix 1
and 2), or backed up in a file. Backup to an USB memory (or internal file) can be done
from menu 'Maintenance', sub menu 'Create Backup'.
Appendix 1 and 2 to this manual contains suitable forms to fill in for the instrument
hardware configuration and for the set-up parameters, covered by this manual.
Hardware configuration
The instrument G4, type RM, has room for one fieldbus module and three other
modules. The configuration of installed modules, used measuring channels, and
scale numbers is made in set-up parameter menu 'Hardware Config.'.
At delivery of an instrument, the hardware configuration normally corresponds to
the set-up. If any mismatch between installed modules and hardware configuration
occurs, an error message will be shown at instrument start-up.
Consult 'G4 Multi Channel Weighing Instrument Technical Manual RM type'
if you need to change the hardware configuration.
Security lock
With an instrument G4 it is possible to perform set-up operations during normal
operation, which may influence for example the performance of a scale. To prevent
these dangers, the instrument is equipped with security locks at two levels that can
be activated to protect from unauthorized access to editing of parameters and values.
Four-digit codes for the locks can be defined by the customer.
By default setting the code for both locks is: 1 9 3 7 .
