G4 Multi Channel Weighing Instrument
1. Introduction
General
In the current program version the ‘G4 Modular Weighing Instrument’ includes a
program option for ‘Batching’. The option can be activated by a code specific for each
individual instrument. The code can be ordered from Nobel Weighing Systems and
should be entered in menu ‘Program Options’ in ‘Parameter Set-up’ under the
instrument ‘Main Menu’.
This manual should be used as a supplement to the ‘Technical Manual’ for the
‘G4 Modular Weighing Instrument’. It describes in detail the batching functionality.
Note that this manual can be used for all instrument types (PM, DT, HE and RM) while
the Technical Manuals are different for instruments with graphical display (PM, DT and
HE) and for the alphanumerical display instrument (RM).
When batching with multiple scales, more digital inputs and outputs may be needed.
Connection of external Ethernet WAGO I/O modules will add up to 128 inputs and 128
outputs.
Front panel
Graphical display
The following section applies to the graphical operating display used in the PM, DT and
HE instrument types.
This type of instrument with a graphical display is well suited for use as a complete
multi scale batching system including an easy to use operator interface. Push buttons
on the front panel are used to start, stop, reset etc. It will also display necessary
batching status, alarms etc. The instrument can also be remotely controlled from a
supervising computer (PLC, SCADA system etc).
RM-instrument display
The following section applies to the alphanumerical display used in the RM (DIN rail
mount) instrument type.
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).

2. Batching principles
General
Batching with the G4 Instrument means performing up to 12 activities in numerical
order as one sequence for each scale. Batching can be used with each used scale
in the instrument. Each Scale Batching sequence operates independent of the
other. The batching sequence can be repeated a defined number of times. As
batching is performed, the instrument function is supervised and possible alarms
will be given. Printing of alarms and batched weights can be performed on a
connected printer, note that all scales / batching sequences share the same
printer. The batching events can also be written to a log file in the instrument.
Each scale will generate (if configured) it’s own log file.
Digital inputs and outputs
The instrument uses digital outputs and inputs to control and monitor the batching
process. If the number of internal inputs and outputs (inputs and outputs on IO
modules in the instrument) are not sufficient it is possible to use a WAGO-I/OSYSTEM 750 to increase the number of inputs and outputs in a batching system.
See the ‘Technical Manual’ and the documentation, covering the WAGO I/O
SYSTEM, supplied by WAGO.
Outputs can be divided in two categories (regarding batching). First there are
indications used by an operator (lamps etc.) or by a supervising computer to
monitor the status of the batching. Secondly there are outputs used to control the
batching process, batching valves, heaters, stirrers etc.
Internal outputs can be used for both categories while external outputs (WAGOI/O-SYSTEM) are dedicated as batching process controls.
Inputs can be divided into three categories: First there are control signals used by
an operator (buttons etc) or a supervising computer to control the batching
sequence. These signals are start, stop, restart, reset, reset alarm etc. Secondly
there are acknowledgement signals used as interlocks in the batching process.
Thirdly there are pulse-counting inputs for pulse batching activities where the
number of pulses corresponds to the amount of material batched.
Internal inputs can be used for all three categories while external inputs (WAGOI/O-SYSTEM) are dedicated to acknowledgement signals.
Internal inputs and outputs are configured in menu ‘Parameter Set-up / Inputs’ and
‘Parameter Set-up / Outputs’. See the ‘Technical Manual’ chapter ‘Set-up’. Note
that internal inputs and outputs must be set to ‘Batch Activity’ (the default value) to
be used in batching activities.
A digital input may be used in activities belonging to more than one scale (i.e. it is
possible to share inputs between scales).
A digital output may only be used in activities belonging to one scale (i.e. it is not
allowed share outputs between scales).

Technical Manual Supplement
Batch start check
When batching is started (start button or communication start command) an I/O
usage check is done to verify that all the rules described above are followed.
This check is only done for the scale to start. If there are any violations to the I/O
usage rules there will be an error and the batching sequence will not start. Note
that if any batching is running editing of parameters is not allowed, except for
some activity parameters. It’s therefore recommended that all settings are
properly tested before full production begins.
Batching activities
The following types of activities are available for the batching sequence:
Weigh In
used to batch a component into the weighed vessel (batch in).
Weigh Out
used to batch from a previously filled, weighed vessel (batch out).
Displayed weight during Weigh Out is always negative.
Dump
used to empty a vessel into which components have been
batched.
Fill
used to fill up a vessel to a certain level.
Timer
used to pause the batching sequence for a defined time.
Timer w. Output
used to activate an output for a defined time.
Latch On
used to make an output signal.
Latch Off
used to break an output signal.
Manual
used to halt the batching, making it possible to manually add
special material. Then batching must be manually restarted.
Pulse Batch
used for batching with the aid of pulses from a flow meter.
Setpoint values
The activity types Weigh In, Weigh Out, Timer, Timer w. Output, Manual, and
Pulse Batch require Setpoint values. All Setpoint values can be shown and edited in
menu ‘Batch Data’ under the Batching display. Manual editing (from front panel) of
setpoints can only be done on an instrument with graphical display.
Weigh In and
Weigh Out
The Setpoint value determines the component quantity,
expressed in the measurement unit.
Timer and
Timer w. Output
The Setpoint value determines the duration of the activity,
expressed in seconds with max. one decimal.
The range is 0.0 to 999999.0 seconds.
Manual
The Setpoint value normally determines a small component
quantity to be added manually.
Pulse Batch
The Setpoint value determines the component quantity,
expressed in the pulse batching unit.
The activity types Dump, Fill, Latch On and Latch Off do not require Setpoint values.

3. Activity description
General
In the description of activities below Scale 1 Activity 1 parameters are used as an
example. The parameter names includes the scale number and the activity number.
E.g. ‘1/1:AcivityType’ applies to Scale 1, Activity 1 while ‘3/4:ActivityType’ applies to
Scale 3, Activity 4 etc. Calibration parameters have a prefix that shows which scale the
parameter is belonging to. E.g. ‘1:Capacity’ apply to Scale 1.

Technical Manual Supplement
Weigh In
The Weigh In activity is used when the material is batched into the weighed vessel.
Setpoint check
When a Weigh In activity is started, the Setpoint value is checked to determine if the
receiving container has sufficient capacity for the set quantity of material.
The implication of this Setpoint check is that actual Gross weight + Setpoint value must
be less than ‘S1:Capacity’ for the scale.
If the remaining scale capacity is not sufficient the batching sequence will be halted, an
alarm message will be displayed and printed/logged to file. When the alarm cause has
been taken care of the alarm can be reset and the batching restarted.
Acknowledgement check
When the Setpoint value has been checked and accepted, the acknowledgement input
signal is checked according to ‘1/1:Acknowledge Type’ setting’:
•
‘No Test’: No acknowledgement checking is done. The batching sequence
continues immediately.
•
‘At Start’ or ‘Continuous’: An unsatisfactory signal will initiate an alarm and the
batching sequence is halted. The alarm should be reset and the sequence
restarted to continue the batching sequence. The acknowledgement input
signal will then be checked again.
•
‘Wait’ or ‘Wait+Cont.’: The instrument will wait (without alarm) until the correct
acknowledgement input signal is received. When the acknowledgement signal
is correct the batching sequence continues.
Stability Check before batching
If ‘1:Motion Check’ is ‘On’ the instrument waits for the weight to become stable before
Auto taring is performed. Alarm is never initiated by an unstable weight in conjunction
with start of batching. After the instrument is tared it switches to net weight and
displays zero weight.
Batching
Depending on the settings of ‘1/1:Batching Mode’ and ‘1/1:Fine on during Coarse’
parameters there are three different ways that batching can be done.
•
3-2
‘1/1:Batching Mode’ is ‘Fine+Coarse’ and ‘1/1:Fine on during Coarse’ is ‘Yes’:
The coarse output and the fine output are activated. The instrument shows
increasing weight. When the weight reaches ‘Coarse Level’ the coarse output
is deactivated (Coarse Level = Setpoint – Fine Value – Inflight Value). When
the increasing weight reaches ‘Inflight Level’ the fine output is deactivated
(Inflight Level = Setpoint – Inflight Value).
G4 Multi Channel Weighing Instrument
•
‘1/1:Batching Mode’ is ‘Fine+Coarse’ and ‘1/1:Fine on during Coarse’ is ‘No’:
The coarse output is activated. The instrument shows increasing weight. When
the weight reaches ‘Coarse Level’ the coarse output is deactivated and the fine
output is activated (Coarse Level = Setpoint – Fine Value – Inflight Value).
When the increasing weight reaches ‘Inflight Level’ the fine output is
deactivated (Inflight Level = Setpoint – Inflight Value).
•
‘1/1:Batching Mode’ is ‘One Phase’:
The output is activated. The instrument shows increasing weight. When the
increasing weight reaches ‘Inflight Level’ the output is deactivated
(Inflight Level = Setpoint – Inflight Value).
The ‘1/1:Inflight Value’ is adjusted automatically after each batching if the activity
parameter ‘1/1:Inflight Factor’ is set to a value higher than zero.
Waiting after batching
The instrument waits equivalent to ‘1/1:Wait Time’, a time that must be set so that all
material is really stable on the scale before the waiting time has expired.
Batching timeout
The total batching time for the activity is monitored and if the time exceeds the set
‘1/1:Timeout Value’, an alarm will be initiated. Timeout count will start when the
acknowledgement signal is received and stop during possible batching halts.
Timeout count starts all over again when a Timeout alarm has been reset and
batching has been restarted.

Stability check after batching
After the complete batching of a Weigh In (or Weigh Out) activity and Wait time,
a stability check is performed if ‘1:Motion Check’ is ‘On’ (stability check is never
performed for a Pulse Batching activity).
Unstable weight initiates an alarm. A new weight stability check is performed at
restart, implying that the weight MUST be stable for the instrument to continue the
batching sequence. If stable weight cannot be obtained, batching must be reset or
the ongoing activity skipped.
Tolerance check
The batched weight is always checked against the set tolerance limits. One parameter
defines the ‘1/1:Minus Tolerance’ (weight below the Setpoint value) and the other
defines the ‘1/1:PlusTolerance’ (weight above the Setpoint value). The tolerance setting
range is 0.00 - 100.00 %.

G4 Multi Channel Weighing Instrument
100.00 % means that tolerance check is not performed (all weights are approved).
5.00 % means that the batched weight is permitted to deviate from the Setpoint value
by 5 % thereof.
If the weight is below the ‘1/1:Minus Tolerance’ limit, and a ‘1/1:Pulsing Time’ other
than zero is selected, the fine output will be activated again for the time defined by the
parameter ‘1/1:PulsingTime’. After the ‘1/1:Wait Time’ a renewed tolerance check will
be performed.
If the weight value is still below the ‘1/1:Minus Tolerance’ limit, pulsing of the fine
output will be performed repeatedly until the weight value is above the
‘1/1:Minus Tolerance’ limit. Selection of a ‘1/1:Pulsing Time’ other than zero makes it
possible to ensure that the obtained batch weights will never be below the
‘1/1:Minus Tolerance’ limit.
If ‘1/1:Pulsing Time’ is zero and the weight
value is below the ‘1/1:Minus Tolerance’
limit, batching will recommence in the fine
phase if the remaining weight up to the
Setpoint value is greater than the
‘1/1:Inflight Value’.

In other cases an alarm will be obtained.
An alarm is always obtained if the weight
value exceeds the ‘1/1:Plus Tolerance’
limit.
The operator can bypass these tolerance
alarms by resetting the alarm and
restarting the batching sequence. Either
the erroneous weight can be accepted or
other manual adjustments can be made
before batching is restarted. When
restarting after a tolerance alarm a second
tolerance check will not be performed but
the actual weight will be used for
accumulation and printing.

Technical Manual Supplement
Automatic inflight compensation
Automatic inflight compensation is operative when the ‘1/1:Inflight Factor’ has a value
higher than zero. It is used to adjust the ‘1/1:Inflight Value’ after each activity to bring
the batched weight value as close to the Setpoint as possible.
Automatic inflight compensation for any activity is performed by:
New Inflight value = preceding Inflight value + (batched weight - Setpoint value) x
‘1/1:Inflight Factor’.
The range of the ‘1/1:Inflight Factor’ is 0 - 100 % (0 % means no compensation).
A 50 % Inflight factor adjusts the ‘1/1:Inflight Value’ by 50 % of the difference between
batched weight and Setpoint value.
The previous figure describes the ‘1/1:Inflight Value’ adjustment. Usually, the
difference between batched weight and Setpoint value is the starting point for the
changes.
The difference between batched weight and Setpoint value is limited to the largest
value of:
Setpoint value × ‘1/1:Plus Tolerance’ or
Setpoint value × ‘1/1:Minus Tolerance’.
This limitation ensures that the correction (for example, by a possible tolerance error)
will not be completely unreasonable. The correction of the ‘1/1:Inflight Value’ is always
limited to 10 % of the Setpoint value.
Note that the inflight value is only calculated once, even in pulsing is made several
times.
Weigh Out
Weigh Out is very similar to Weigh In, but batching is done from an already filled
vessel. The only difference being that the Setpoint value is checked to determine that
a sufficient material quantity is available in the container. The requirement
is for the gross weight to be larger than the Setpoint value + 20 × ‘1:Resolution’.
If this requirement is not satisfied an alarm is initiated.
The weight display during this type of batching is always negative.
Pulse Batching
The Pulse Batching activity is very similar to the activities Weigh In and Weigh Out, but
the Pulse Batching activity does not use the measured weight value for the batching.
Instead it counts pulses (normally from a flow meter) that are scaled to a weight,
volume or any other unit. Another difference is that there are no stability and setpoint
checks included in the Pulse Batching sequence.
There are four more parameters in this activity, defining the input for pulses
’1/1:Pulse Input No’, the number of decimals for Pulse Batching ‘1/1:No of Decimals’,
the Pulse Batching unit ‘1/1:Unit’, and the number of pulses/unit ‘1/1:Scale Factor’.
NOTE! For a Pulse Batching activity the weight in this manual should be read as
‘No of counted pulses’ × ‘1/1:Scale Factor’.

Dump
Only emptying of the vessel into which the components have been batched is
performed by this activity.
Acknowledgement check
The acknowledgement input signal is checked according to ‘1/1:Acknowledge Type’
setting’:
•
‘No Test’: No acknowledgement checking is done. The batching sequence
continues immediately.
•
‘At Start’ or ‘Continuous’: An unsatisfactory signal will initiate an alarm and the
batching sequence is halted. The alarm should be reset and the sequence
restarted to continue the batching sequence. The acknowledgement input
signal will then be checked again.
•
‘Wait’ or ‘Wait+Cont.’: The instrument will wait (without alarm) until the
acknowledgement input signal is received. When the acknowledgement signal
is correct the batching sequence continues.
When the acknowledgement signal is correct the instrument switches to display of
gross weight.
Dumping
The dump output, defined in parameter ‘1/1:Output No’, is activated. When the gross
weight has come down to the ‘1/1:Low Level’ a timer is started. This is a low-weight
value, which is used to obtain a detectable weight value close to zero.
After a time equivalent to ‘1/1:Wait Time’, the dump output is deactivated. Wait time
must be selected long enough to allow all material left at the dump low level to leave
the vessel during this time.
Dumping timeout
The total dumping time is monitored and if it exceeds the
set ‘1/1:Timeout Value’, an alarm will be obtained. Timeout
count will start when the acknowledgement signal is
received and stop during possible batching halts.
Timeout count starts all over again if a Timeout alarm has
been reset and dumping has been restarted.

more is done in the activity.
When the gross weight has come up to the

The instrument counts down the time corresponding to Setpoint value (the count-down
can be watched on the display). If batching is restarted after a temporary halt (due to,
for example, an alarm) the time count starts from where it was stopped.
When the time has expired the output is deactivated (if it was active).

Manual
A Manual activity halts the batching to allow special operations that must be carried out
manually. (For example, to add small quantities of material manually.) Before batching is
halted autotaring is performed, which means that the net weight zero is displayed when
the manual operation starts.
Batching must be restarted either by giving a Restart Command (communication or
digital input) or manually by pressing the START button (only on PM/DT/HE instrument).
If ‘1/1:Print Weight’ is ‘Yes’ then the weight value (weighed by the scale or entered
manually) will be added to the accumulating registers and printed. Parameter
‘1/1:Enter Weight’ defines whether the operator shall have the opportunity to enter the
weight value for the added material manually, or not. If parameter ‘1/1:Enter Weight’ is
‘Yes’ but the operator does not enter a weight value manually, then the weight value
from the scale will be used. A “manual entered weight” sent by communication is used
in the same way as if the operator enter a value from the front panel.

4. Batching parameters
Changing and storing
Batching menus and batching parameters will only be displayed if the user has entered
a valid option code for the Scale Batching Program Option. See the ‘Technical
Manual’, for the relevant instrument type, for details on how to enter option code, how
parameters are handled (editing, saving etc), how calibration etc. is performed. It is
advisable to make all necessary basic set-ups like hardware configuration, calibration
etc. before continuing with the batching setting.
Data entered to define batching parameters are permanently stored in the instrument
and will not be lost if the instrument is switched off.
Certain activity parameters are of a conditional type, implying that they do not
appear unless another parameter has a certain value. These conditions are given
in the explanation text for the parameters.
The Scale Batching Program Option is available both on the PM/DT/HE graphical
display instrument type as well as on the RM alphanumerical display instrument type.
The same parameters are available on all instrument types but the spelling of the
parameter names differ for the RM type. In the list below are the RM type parameter
names written within brackets. The name used on a graphical display type of
instrument is shown first on the row without brackets. The same applies to menu
names. In the explanation part for parameters references only the graphical display
type of instrument naming is used. The RM type of naming will be found for the
respective parameter.
The G4 Multi Channel Instrument can handle batching for up to 8 scales
depending on the number of measuring channels installed in the instrument. In the
parameter list below are the parameters for scale number 1 shown. The same
parameter list is available for all installed scales. The parameters for each scale is
grouped in it’s own sub menu. The prefix S1 – S8 is used to distinguish
parameters belonging to the different scales. For each scale there are 12 activities
available. The parameters for each scale and activity are distinguished by it’s
prefix; ‘1/1:Activity Type’ or [‘1/1:Act. Type’] is the activity type parameter for
scale 1, activity 1, ‘5/11:Activity Type’ or [‘5/11:Act. Type’] is the activity type

5. Operation
General
This chapter describes how the batching operator interface works and is handled. Note
that possible references to parameters are, as an example, done with scale 1 and
activity 1 in the following chapters.
PM/DT/HE instrument display
The following section applies to the graphical display used in the PM/DT/HE instrument
types.
When the G4 Instrument is in normal operation, displaying the weight value, and
the batching option is activated, this is indicated by the text “Batch” at the function key
to the left (F1). Pressing that key will open the batching display provided that activities
are configured for the selected scale. The F1 (Batch) key is dimmed if no activities are
configured for the selected scale.
The selected scale in the weight display will also be shown when entering the batch
display.
The Weight display is shown and the batching program option is activated (here in
demo mode).
Pressing F1 (Batch) will show the batching display unless F1 is dimmed (se above).

Batching display
The batching display shows the actual weight and status for the selected scale. The
display also shows all necessary information of the batching sequence that an operator
needs to handle the batching process. Scales that are not batching will display status
‘Inactive’.
It is possible to change the selected scale by pressing ‘↑’ or ‘↓’ key or pressing a digit
key corresponding to the wanted scale number. Only scales with configured activities
will be shown in the batching display.
The batching status is displayed on a colored background with the following
colors:
Green: batching active
Yellow: batching sequence halted (manually halted, by manual activity or after
batch alarm reset).
Red: there is an alarm (the sequence is halted).

Batch Data Menu
From the batching display it is possible to reach a setup menu for batch data using
key F1 ‘B.Data’. Batch data can be changed during batching but will not take effect
until next batch is started.
Batch data are settings for number of batches, batch size and activity setpoints.
Number of batches and batch size are optional data controlled by set-up parameters.
Activity setpoints such as weights or times are displayed and possible to change from
the batch data menu. Weight or time setpoint depends on the type of activity.
Note that batch data also can be changed via communication.

No of Batches:
If activated it shows the number of batches to perform. If this line is not activated only
one batch at a time can be performed. Number of batches can be edited in the range
1 to 999999.
Batch size:
If activated it shows the size of one batch, in percent or in weight. If this line is not
activated, the batch size is the sum of all Setpoint values without scaling, for the
activity types ‘Weigh in’, ‘Weigh out’, ‘Manual’, and ‘Puls batch’.
If percentage is shown, the Setpoint values (except for Timer) will be scaled by that
percentage. Batch percentage can be edited in the range 1 to 999999 %.
If weight is shown, the Setpoint values (except for Timer) will be scaled to produce the
wanted batch size. Batch weight can be edited in the range 0.001 to 999999.0 units.
NOTE! Strange effects may appear if ‘1/1:Unit’ for a Pulse batch activity differs from
‘1:Measurement Unit’ for the instrument, or if ‘Weigh In’ and ‘Weigh Out’ activities are
used in the same batching sequence.
Setpoints:
All used activities are listed. Each line shows the activity number (A1: etc.), the activity
name (parameter ‘1/1:Activity Name’) and actual Setpoint value or type of activity for
an activity without setpoint. Setpoint values can be edited in the range 0 to 999999
units or seconds. If a setpoint is set to 0 this activity will be skipped. I.e. the activity will

RM-instrument display
The following section applies to the alphanumerical display used in the RM (DIN rail
mount) instrument type.
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.)
and monitoring of the batching sequence should a supervising computer be used
(a PLC, a SCADA system etc).
An animated symbol is shown in the weight display, when batching is active
(running) for the selected scale.

Batching commands
General
Below a description is given for how batching commands are given from the front panel
of the G4 Instrument. Note that this description applies to an instrument with a
graphical display (PM/DT/HE types).
Batching commands can also be given from a control computer by communication or
from digital inputs, defined in menu ‘Parameter Set-up’ / ‘Inputs’.
Note that the Batching display must be shown to be able to manually control the
batching sequence from the front panel of the instrument. It is also possible to fully
control the batching sequence (start, stop etc) with communication commands or by
using digital I/O. Communication commands or digital I/O commands do not require
that the batching display is shown on the screen. When using a RM type of instrument
commands can only be given with communication or digital I/O’s.
Important
When using the front panel to control the batching process push button commands,
front panel inputs (manually entered weight) etc. applies to the selected scale. The
selected scale is the one shown on the batching display. Use ‘↑’ and ‘↓’ keys or press
a digit key corresponding to wanted scale number to select which scale that should be
selected (shown on the batching display). Only scales that have configured activities
will be shown.
Also note that it is possible to leave the batching display showing the weight display or
menu system. This will not interrupt batching. To be able to (manually from the front
panel) stop or in any other way influence batching sequences, the user must return to
the batching display.
If it is important to immediately, without having to move between the displays, stop or
in any other way control the batching, use communication commands or digital I/O.
Note that communication commands and digital I/O commands can be used in parallel
with commands from the front panel (batching display).

Batched weights
For each scale an accumulated weight will be created for each batching activity of
the types Weigh In, Weigh Out, Manual (if ‘1/1:Print Weight’ is ’Yes’), and Pulse
Batching.
For each scale will also a Total accumulated weight be created for the sum of all the
above activities. Pulse batching values will be added to ‘Activity total’ only if the
‘1/1:Unit’ for Pulse Batching is equal to ‘Measurement unit’.
In the sub menu ‘Batched Weights’, in the ‘Main Menu’, are the accumulated weights
for each configured scale to be found. The menu ‘Batched Weights’ is only shown if
the Scale Batching Program Option is enabled. Each batched weight can be edited i.e.
for zeroing.
There is also a possibility to zero all batched weights for a scale form this menu:
•
By pressing the F3 (Zero) button on an instrument with graphical display
(PM/DT/HE instrument).
•
By finding the “Zero ALL values’ function, after the last accumulated value, on
an instrument with an alpha numerical display (RM instrument).
The instrument is capable of storing batched weight values up to 10 000 000 000 units
with 3 decimals. When the limit is passed 10 000 000 000 will be subtracted from the
value.
Printing
Printout of batching reports will be performed automatically according to the setting of
parameter ‘S1:Batch Printout’ in menu ‘Scale 1 Batching Params.’:
•
‘No’: No reports will be printed.
•
‘Full Report’: Reports will be printed containing a report header, the batch
number, batched weight values and other information (like Latch on, Latch off,
Timer ready etc). A complete and coherent report will be printed after each
batch. Alarms will be printed as they occur, i.e. between reports.
•
‘Limited Report’: Reports will be printed containing a report header, the batch
number and batched weight values. A complete and coherent report will be
printed after each batch. Alarms will be printed as they occur, i.e. between
reports.
•
‘Only Alarms’: Alarms are printed when occurring together with date and time.
•
‘Log Mode’: Report header, batch number, batched weight values, alarms that
have occurred and other information (like Latch on, HALTED etc.) will be
printed. Each event will be printed as it occurs.

6. Log files
General
The G4 Instrument has the possibility to log batching information to file. Each scale
has it’s own log file. The log file is named S1BATCH.LOG for scale no. 1,
S2BATCH.LOG for scale no. 2 etc. The file is a plain text file with tab. separated data.
Each position (column) has a defined type of information contents. See file format
description below. The batch log file can be opened e.g. in MS Excel.
The configuration of file logging is made in set-up parameter ‘S1:File Log’:
•
‘No’: No logging to file is made.
•
‘Limited’: Only batched weights and alarms are logged.
•
‘Full’: Batched weights, alarms and other information are logged.
Log file handling
Log files are saved in the ‘LogFiles’ folder in the user area of the G4 Instrument. It is
possible to access these files with the ‘File Handling’ function in the ‘Maintenance’
menu. Log files can be copied or moved to an USB memory for storing, analyzing,
processing etc. on a computer. It is advisable to remove log files on a regular basis to
avoid running out of disc space in the G4 Instrument. If disc space is low an alarm will
be issued but batching can be continued after resetting the alarm. However the log
files will not be written as long as disc space is low.
The log file in the example above is about 2.3 kB or average 50 bytes per line. It is
recommended not to exceed 2 MB totally. Note that the available disc space may be
limited if many backup files or other files are stored in the instrument.
When a log file has been removed from the instrument a new log file will be created
automatically. Avoid accessing the log files when batching is running since it may
cause a file access error alarm.
It is possible to access the user area using an ftp client. Use the user ID ‘G4User’ with
the (default) password ‘1937’ to log on to the instrument. Using the ftp makes it
possible to, either manually or automatically, delete log files, move log files to an
external computer for storage etc. See the ‘Technical Manual’ chapter
‘Communication’ about the ftp Server.

7. Batching alarms
General
When a batching alarm is initiated, the following events take place:
•
Batching is halted and all batching outputs are deactivated.
•
The outputs for ‘Batching Alarm’ and ‘Batching Stopped’ will be activated if
configured.
•
An alarm message is displayed on the Batching display and Weight display.
Displaying batching alarms on the Weight display for one scale is configurable.
Two and four scales displays will always show alarm messages.
•
An alarm report may be printed depending on the settings. A alarm event may
be written to the log file if configured.
Whenever an alarm has been obtained, alarm reset and restart of batching are
required (manually on an instrument with graphical display by pressing the ‘F2’ key
A.Reset and thereafter the START key). If restart of batching is not possible, batching
must be terminated (by pressing the STOP key) or the activity must be skipped (by ‘F3’
Skip Act.). After a restart the instrument will continue the batching sequence.
Batching alarms
* SETPOINT ALARM *
•
Weigh in: The vessel, being batched to, does not have sufficient volume to
contain the desired quantity of material (the gross weight will exceed
Capacity).
•
Weigh out: The contents of the vessel (gross weight) is not sufficient to
batch out the desired quantity of material.
* ACKNOWLEDGE ALARM *
The alarm is caused by absence of acknowledgement signal.
Instrument behavior depends on the selected acknowledgement type set by parameter
‘1/1:Acknowledge Type’:
•
No Test: An alarm is never obtained in this case.
•
At start: An acknowledgement signal was not present at start of activity.
•
Wait: An alarm is never obtained in this case.
NOTE! If an acknowledgement signal is not present, the instrument waits for an
acknowledgement signal for any length of time, displaying the text
‘Waiting for Ack.’.
•
Continuous: The acknowledgement signal was cancelled during the activity or
was not present at starting.
•
Wait+Cont.: Identical to Wait until start of activity, after that identical to
Continuous.
7-1
Technical Manual Supplement
* TIMEOUT ALARM *
The activity was not completed within the specified maximum time, set by parameter
‘1/1:Timeout Value’.
* MINUS TOLERANCE ALARM *
Batched weight is below minus tolerance limit.
* PLUS TOLERANCE ALARM *
Batched weight exceeds plus tolerance limit.
* UNSTABLE WEIGHT ALARM *
Weight not stable after Wait time (obtained only if Motion Check is On).
* WEIGHT ERROR ALARM *
The weight is incorrect (e.g. transducer or weight converter fault).
* FILE WRITE ERROR ALARM *
There was an error when writing to a log file. This can occur if an external computer is
accessing a log file when the instrument attempts to write to the same log file.
* OUT OF DISK SPACE ALARM *
The instrument is low on disk space. No data will be written to the Scale Batching log
files. It is necessary to remove files from the user folders in the instrument to allow
data to be written to the log files.
* POWER FAIL ALARM *
A power fail has occurred. This alarm will be displayed when the instrument is powered
up after a power fail situation.

If the register for the manually entered weight has been written when ‘Batching Status’
is ‘Batching halted for manual operation weight entry’ (05), the value in the register will
be used as manual entered weight when batching is restarted.
Note that the Integer register, the Float register and the manually entered weight from
the front panel (PM/HE/DT instrument types) are “parallel” and that the latest entered
value will be the value that is used (printed and accumulated) when batching is
restarted.
Also note that the manually entered weight is only used if the parameter
‘1/1:Enter Weight’ is set to ‘Yes’.

R/W
Batched weight is represented by two values (HIGH, LOW). To get the resulting value
multiply value HIGH by 10000 and add value LOW. LOW is a value between
±9999.999 with 3 decimals. HIGH is a value without decimals between ±999999. To
zero a batched weight, send 0 to both HIGH and LOW.
NOTE! Both HIGH and LOW must be written in ONE Modbus message on order to
change the value.
