G5 Weighing Instrument
5-1
5. Operation
General
G5 instrument with strain gauge transducers is designed mainly for weighing and
batching purposes. The measurement values are displayed at the front panel, and can
also be transmitted to a master computer/PLC.
A measurement values can also be presented as an analog output signal.
Some functions in the instrument can be controlled by digital input signals, and digital
outputs from the instrument can be used to indicate actual status of instrument, scale,
levels and so on.
The instrument is powered by 24 VDC.
Power-up sequence
As the G5 instrument is started it enters the Starting up state.
If any error is detected during power-up, the sequence stops and an error code
will be displayed. If the error is not fatal it will be possible to enter the menu system to
correct possible set-up errors.
If the detected error is fatal, it will only be possible to select restart. If the fatal error
persists please contact your supplier.
If no errors are detected, the instrument can enter normal operation (automatic
start-up), displaying actual weight values, possibly together with other instrument
information.
If ‘Manual start-up’ is selected, the instrument enters the ‘Wait for start’ state,
displaying a message ‘Waiting for start command. Press START to continue!’.
When the operator presses the ‘START’ button (‘F1’) on the screen, the
instrument will switch over to normal operation unless a warm up time is set and
there is still a remaining warm up time. In this case the ‘Warming up’ message
will be displayed. See below.
If a warm up time has been set the message ‘Warming up.’ will be displayed
together with the remaining time. When the warm up time has expired the
instrument will switch over to normal operation automatically.
