Introduction
The 920i is a programmable, multi-channel digital
weight indicator/controller. The configuration can be
performed using the front panel, with an attached
PS/2®1-type keyboard, or using the iRev 4 utility.
Custom event-driven programs can be written with the
iRite language up to 512K in program size. These
programs are compiled with an iRite compiler utility,
which can only be downloaded into the indicator. The
RLWS Web Update utility can be used to download
920i firmware upgrades to a PC from the RLWS web
site; iRev 4 provides functions for installing the new
software into the 920i.
Onboard Features
Features of the basic 920i include:
• Support for A/D scale or serial scale inputs.
The maximum number of scale inputs is 28;
these can be combined to represent up to 32
scale configurations.
• Six digital I/O channels on main board, each
configurable as either input or output.
• Four serial ports on main board (Ports 1–4)
support duplex RS-232 up to 115200 bps. Port
2 supports hardware handshaking and remote
keyboard input; Ports 3 and 4 support 20mA
output; Port 4 supports 2-wire RS-485
communications.
• External DB-9 and DIN-8 connectors for
serial connection to a PC and attachment of
PS/2-type remote keyboard.
• Available in 115 VAC and 230 VAC North
American and European versions.
1.
Some procedures described in this manual
require work inside the indicator enclosure.
These procedures are to be performed by
qualified service personnel only.
PS/2® is a registered trademark of IBM Corporation.
Other features include:
• 62K of non-volatile RAM can be allocated to
databases using the iRev 4 database editor.
• Configurable print formats can be defined for
up to 1000 characters each. These formats are
used to print gross or net weights, truck in/out
weights, setpoint weights, accumulator
weights, alert messages, and header
information. Additional print formats can be
created with iRite.
• Six truck modes to store and recall weights
for gross, tare, and net printing. The truck
register contains fields for ID number, weight,
and the transaction time and date. Weights can
be stored permanently or erased at the end of
the transaction.
• The setpoint engine supports 31 configurable
setpoint kinds. Setpoints can be arranged in a
sequential batch routine of up to 100 steps. If
setpoints are configured as free running
setpoints, they can be tied to program control.
This allows for simultaneous batching
operations to be written with the iRite
language.
The 920i is NTEP-certified for Classes III and III L at
10,000 divisions. See Section 10.14 on page 127 for
more information about additional certifications and
approvals.

Enclosures
The 920i is available in four enclosures: universal
(tilt-stand), deep enclosure, panel mount, and wall
mount. Stainless steel enclosures are rated for NEMA
4X/IP66. This manual provides assembly drawings
and replacement parts lists for the universal model;
supplemental documentation provides information
specific to the panel mount and wall mount models
(Section 1.4 on page 4).
1.1
Operating Modes
The 920i has two modes of operation:
Normal mode
Normal mode is the weighing mode of the
indicator. The indicator displays gross, net, or tare
weights as required, using the secondary display
to indicate scale status and the type of weight
value displayed. Once configuration is complete
and a legal seal is affixed to the large fillister-head
screw on the indicator enclosure, this is the only
mode in which the 920i can operate.
Setup mode
Most of the procedures described in this manual
require the indicator to be in setup mode,
including configuration and calibration.
To enter setup mode, remove the large fillister
head screw from the enclosure. Insert a
screwdriver or a similar tool into the access hole
and press the setup switch once. The indicator
display changes to show scale configuration
menus.
1.2
Indicator Operations
Basic 920i operations are summarized below:
Toggle Gross/Net Mode
Press the GROSS/NET key to switch the display mode
from gross to net, or from net to gross. If a tare value
has been entered or acquired, the net value is the gross
weight minus the tare. If no tare has been entered or
acquired, the display remains in gross mode.
Gross mode is indicated by the word Gross (or Brutto in
OIML mode); net mode is indicated by the word Net.
Toggle Units
Press the UNITS key to switch between primary,
secondary, and tertiary units.
Zero Scale
1. In gross mode, remove all weight from the scale
and wait for the standstill annunciator (
).
2. Press the ZERO key. The center of zero (
)

end-of-life stage.
There is no SDRAM module on the back side
as the memory is now on the main board.
Added two additional DIO points, 5 and 6.
The new boot monitor V1.13 has mapping for
the new memory.
The new board requires minimum version
3.14 or newer. Version 3.14 supports iQUBE
while 4.xx supports iQUBE2.
Version 4.0
•
Added support for iQUBE2 and removed
support for iQUBE.
NOTE: Version 4.0 requires Rev E CPU board or newer.
Version 3.13
•
•
•
Added a new value <AN> to the Print
Formatting section of the manual (see Section
6.1, Table 6-1 on page 60).
Corrected comparisons to reduce the number
of power-up calibrations counted by Audit
Trail.
Added the speed-up of loading a user program
by only erasing needed memory blocks.

Error Recovery - version 3.10.00 of the 920i
now has a very sophisticated error recovery
for the battery backed NVRAM. when a Save
and Exit is performed after a Configuration
and Calibration is performed, a copy of the
N VR A M i s s t o r e d i n F l a s h f o r f u t u r e
recovery. If the 920i is powered off at any
time and the battery is not at peak
performance, the NVRAM could come up
with corrupted data. The next time the 920i is
powered up, the NVRAM is tested for a
correct CRC checksum. If this is bad, there
will be a special screen displayed showing the
corrupt locations with directions to press
ENTER to continue. The core will rewrite to
NVRAM using the last copy of the last Save
and Exit. At this time Date and Time are also
checked. It will then open the Date/Time full
screen edit function so the operator can check
the current Date and Time. If correct, all that
is needed is an ENTER key to continue. If
incorrect, the operator can adjust the Date or
Time and then push ENTER to continue. 
To ensure the latest copy of NVRAM is
available for a power up, it is recommended
that before powering down the 920i for either
overnight outage or temporary storage, the
unit should be put into setup mode and a Save
and Exit performed which will save a new
copy of the NVRAM. On Legal-For-Trade
units, if this cannot be performed, then the

replacement parts lists for the universal model are
included for the service technician. See Section 10.12
on page 122 for dimension drawings of the all models.
2.3
The universal model of the 920i provides six cord
grips for cabling into the indicator: one for the power
cord, five to accommodate cabling for option cards.
Install plugs in all unused cord grips to prevent
moisture from entering the enclosure.
2.3.1

•
2.1
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when working inside the
indicator enclosure.
This unit uses double pole/neutral fusing
which could create an electric shock hazard.
Procedures requiring work inside the
indicator must be performed by qualified
service personnel only.
The supply cord serves as the power
disconnect for the 920i . The power outlet
supplying the indicator must be installed near
the unit and be easily accessible.
Unpacking and Assembly
Immediately after unpacking, visually inspect the 920i
to ensure all components are included and
undamaged. The shipping carton should contain the
indicator, this manual, and a parts kit. If any parts
were damaged in shipment, notify Rice Lake
Weighing Systems and the shipper immediately.
See Section 2.10 on page 17 for parts kit contents.
2.2
Enclosure Disassembly
The indicator enclosure must be opened to install
option cards and to connect cables for installed option
cards.
Cable Connections
Cable Grounding
Except for the power cord, all cables routed through
the cord grips should be grounded against the
indicator enclosure. Do the following to ground
shielded cables:
• Use the lockwashers, clamps, and kep nuts
provided in the parts kit to install grounding
clamps on the enclosure studs adjacent to cord
grips. Install grounding clamps only for cord
grips that will be used; do not tighten nuts.
• Route cables through cord grips and
grounding clamps to determine cable lengths
required to reach cable connectors. Mark
cables to remove insulation and shield as
described below:
• For cables with foil shielding, strip insulation
and foil from the cable half an inch (15 mm)
past the grounding clamp (see Figure 2-1).
Fold the foil shield back on the cable where
the cable passes through the clamp. Ensure
silver (conductive) side of foil is turned
outward for contact with the grounding
clamp.
• For cables with braided shielding, strip cable
insulation and braided shield from a point just
past the grounding clamp. Strip another half
inch (15 mm) of insulation only to expose the
braid where the cable passes through the
clamp (see Figure 2-1).
The 920i has no on/off switch. Before
opening the unit, ensure the power cord is
disconnected from the power outlet.
Ensure power to the indicator is disconnected, then
place the indicator face-down on an antistatic work
mat. Remove the screws that hold the backplate to the
enclosure body, then lift the backplate away from the
enclosure and set it aside.

2.3.2
For load cell cables, cut the shield wire just
past the grounding clamp. Shield wire
function is provided by contact between the
cable shield and the grounding clamp.
Route stripped cables through cord grips and
clamps. Ensure shields contact grounding
clamps as shown in Figure 2-1. Tighten
grounding clamp nuts.
Finish installation using cable ties to secure
cables inside of indicator enclosure.
When connections are complete, reinstall load cell
connector on the A/D card and use two cable ties to
secure the load cell cable to the inside of the
enclosure.
Load Cells
To attach cable from a load cell or junction box to an
installed A/D card, route the cable through the cord
grip and ground the shield wire as described in
Section 2.3.1 on page 8.
Next, remove connector J1 from the A/D card. The
connector plugs into a header on the A/D card (see
Figure 2-2). Wire the load cell cable from the load cell
or junction box to connector J1 as shown in Table 2-1.

Digital I/O
Digital inputs can be set to provide many indicator
functions, including all keypad functions. Digital
inputs are active low (0 VDC), inactive high (5 VDC).
Digital outputs are typically used to control relays that
drive other equipment. Outputs are designed to sink,
rather than source, switching current. Each output is a
normally open collector circuit, capable of sinking 24
mA when active. Digital outputs are wired to switch
relays when the digital output is active (low, 0 VDC)
with reference to a 5 VDC supply.

920i Installation Manual
Digital inputs and outputs are configured using the
DIG I/O menu. See Section 3.2.6 on page 50 for
configuration information.
An optional 24-channel digital I/O expansion card,
PN 67601, is available for applications requiring more
digital I/O channels.
NOTE: Digital I/O points can be configured to count
active pulse inputs by setting them to PROGIN
(DIGIN menu) and using the iRite DigInSsBbActivate
handler with a timer to turn the handler on and off.
However, the fastest pulse rate that can be counted
using a digital input is 10Hz (10 pulses per second).
More demanding applications can use the pulse input
option card (PN 67603) to count pulses in the
4–4000Hz range.
2.4
Installing Option Cards
Each option card is shipped with installation
instructions specific to that card. The general
procedure for all option cards is as follows:
Option cards are not hot-pluggable.
Disconnect power to the 920i before
installing option cards.
1. Disconnect power to the indicator. Remove
backplate as described in Section 2.2 on page 8.
2. Carefully align the large option card connector

Battery Replacement
The lithium battery on the CPU board maintains the
real-time clock and protects data stored in the system
RAM when the indicator is not connected to AC
power.
Data protected by the CPU board battery includes
time and date, truck and tare memory, onboard
database information, and setpoint configuration.
Use iRev 4 to store a copy of the indicator
configuration on a PC before attempting battery
replacement. If any data is lost, the indicator
configuration can be restored from the PC.
NOTE: Memory option card data is also protected by a
lithium battery. All database information stored on a memory
card is lost if the memory card battery fails.
Watch for the low battery warning on the LCD display
and periodically check the battery voltage on both the
CPU board and on any installed memory option cards.
Batteries should be replaced when the indicator low
battery warning comes on, or when battery voltage
falls to 2.2 VDC. Life expectancy of the battery is ten
years.

Configuration
To configure the 920i indicator, the indicator must be
placed in setup mode. The setup switch is accessed by
removing the large fillister head screw on the
backplate of the universal and deep enclosures.
Switch position is changed by inserting a screwdriver
into the access hole and pressing the switch.
3.1
Configuration Methods
The 920i indicator can be configured by using the
front panel keys to navigate through a series of
configuration menus or by sending commands or
configuration data to an indicator serial port.
Configuration using the menus is described in
Section 3.1.3.
Configuration using the serial port can be
accomplished using either the serial command set
described in Section 9.0 or the iRev 4 configuration
utility.
NOTE: Some configuration parameters, such as those
used to configure the 920i display and widgets, cannot
be accessed through the configuration menus. iRev 4
provides the most complete and efficient
configuration interface for the 920i.
3.1.1
iRev Configuration
The iRev 4 configuration utility provides the preferred
method for configuring the 920i indicator. iRev 4 runs
o n a p e r s on a l c o m p u t e r t o s e t c on f i g u r a t i on
p a r a m e t e r s f o r t h e i n d i c a t o r. W h e n i R e v 4
configuration is complete, configuration data is
downloaded to the indicator.
iRev 4 supports both uploading and downloading of
indicator configuration data. This capability allows
configuration data to be retrieved from one indicator,
edited, then downloaded to another indicator with an
identical hardware configuration.
NOTES: If using iQUBE 1, use iRev 3. If using iQUBE2 or no
iQUBE, use iRev 4.
You cannot use iRev 3 to edit a file created in iRev
4. iRev must be newer or the same version as the
file being opened.
22
When the indicator is placed in setup mode, a series of
menus is shown across the top of the display, along
with the words Scale Configuration. The SCALES menu
is highlighted as the first used to configure the
indicator. Detailed descriptions of these menus are
provided in Section 3.2.
When configuration is complete, press the Save and
Exit softkey to exit setup mode, then replace the setup
switch access screw.
920i Installation Manual
Figure 3-1. iRev Hardware Configuration Display
To use iRev 4, do the following:
1. Install iRev 4 on an IBM-compatible personal
computer. See Section 5.0 on page 59 for
detailed hardware and software requirements.
2. With both indicator and PC powered off,
connect the PC serial port to the RS-232 pins
on the indicator serial port.
3. Power up the PC and the indicator. Use the
setup switch to place the indicator in setup
mode.
4. Start the iRev 4 program.
iRev 4 provides online help for each of its configuration
displays. Parameter descriptions provided in this
manual for front panel configuration can also be used
when configuring the indicator using iRev 4 : The
interface is different, but the parameters set are the
same.
See Section 5.0 on page 59 for more information about
using iRev 4 to configure the 920i.
3.1.2
Serial Command Configuration
The serial command set can be used to configure the
920i indicator using either a personal computer,
terminal, or remote keyboard. Like iRev 4 , serial
command configuration sends commands to the
indicator serial port; unlike iRev 4, serial commands
can be sent using any external device capable of
sending ASCII characters over a serial connection.
Serial commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. Serial commands
can be used to simulate pressing front panel keys, to
configure the indicator, or to dump lists of parameter
settings. See Section 9.0 on page 89 for more
information about using the serial command set.
3.1.3
Front Panel Configuration
Use the CONFIG submenu under the SCALES menu
to configure A/D scales. For example, in an indicator
with a single-channel A/D card installed in Slot 1, the
Scale Configuration display will show the A/D listed
(Slot 1 Channel 1) under the AVAILABLE A/D’s column.
Use the left navigation key to select the A/D, then
press the center softkey, Add. The A/D is then moved
to the Associated A/D’s column. If no other A/D’s are
listed in the AVAILABLE A/D’s column, the center
softkey changes to Done , as shown in Figure 3-2.
Press Done to exit the Scale Configuration display.
See Section 10.4 on page 111 for information about
configuring serial scales.
Multi-range scales provide two or three ranges, each
extending from zero to the maximum capacity
specified for the range, that can specify different scale
intervals (graduations). The scale interval changes as
the applied weight increases but does not reset to
lower range intervals until the scale returns to zero.
Multi-interval scales divide the scale into two or three
partial weighing ranges, each with different scale
intervals. The scale interval changes with both
increasing and decreasing loads applied.
To configure a multi-range or multi-interval scale, use
the SPLIT parameter to select 2RNG or 3RNG (for
multi-range scales), or 2INTVL or 3INTVL (for
multi-interval scales). Selecting a SPLIT value other
than OFF allows specification of decimal point,
display divisions, and maximum capacity for each
range or interval.
The SPLIT parameter is used to enable multi-range or
multi-interval. The SPLIT parameter is in the
SCALES menu, see Figure 3-4, and Table 3-2. After
setting the SPLIT parameter, the Format menu
selection will change as shown in Figure 3-6, and
Table 3-4.
If using streaming with multi-range or multi-interval,
the stream must be set to Custom in iRev 4 . The
Tokens for Secondary and Tertiary Units must be set
to L or K to match the Primary, refer to the Serial
Menu, Tokens Parameter, in Section 3.2.2 on page 37.
They can be set using iRev 4 or through the front
panel.
In multi-range, each range has its own capacity and
display division, extending from zero. The scale
display division will increase at the entered range
capacities, either two or three ranges. Once the range
has increased to the next level, the display division
will remain in new range until the scale returns to
zero. The tare value can be taken in any range.
For example,
Range 1 is 0 - 3000 x 1 lb.
Range 2 is 0 - 10,000 x 5 lb.
Figure 3-2. Scale Configuration Display
3.1.4
Multi-Range and Multi-Interval Scales
The 920i supports multi-range and multi-interval
scales of either two or three ranges or intervals.
In multi-interval, the scale has one capacity, which is
segmented into weighing intervals, either two or three
intervals, each with different display division sizes.
As the weight value exceeds an interval or set interval,
the display division will increase, as the weight falls
below an interval or set interval, the display division
will decrease. The tare can only be taken in the first
interval.
For example,
Range 1 is 0-30 x 0.01 lb.
Range 2 is 30 - 60 x 0.02 lbs.
Configuration
23
3.1.5
Total Scale Configuration
The output of two or more A/D scales or iQUBE 2
systems can be configured to function as a total scale.
Once configured and calibrated, the total scale can be
used as a source for other system functions, including
streaming, setpoints, print formatting, and analog
output.
To set up a total scale from the indicator front panel,
use the scale configuration display (see Figure 3-2) to
select the A/D scales or iQUBE2 systems to configure
as a total scale. (Use the Change Type softkey to show
available A/D scales or iQUBE2 systems; use the right
navigation key to select the total scale sources.) In
iRev 4, assign the total scale to an unused position then
select source scales from the existing A/D scales or
iQUBE2 systems.
The FORMAT configuration of the total scale (see
Figure 3-5 on page 30) should match that of the
source scales. However, the value specified for the
total scale GRADS parameter should be specified as
the sum of the GRADS values for the source scales.
For example: if SCALE 1 is set to GRADS=10000,
SCALE 2 to GRADS=5000, SCALE 3 (the total
scale) should be set to 15000 grads.
The total scale will show an over-range indication if
the maximum capacity of any source scale is
exceeded, and show dashes if any source scale reads a
negative value. Source scales will respond to Tare and
Zero operations performed on the total scale.

TROYOZ=troy ounce; TROYLB=troy pound; LT=long ton.
MULT
0.453592
0.000001–
9999999
Multiplier. Specifies the conversion factor by which the primary units are multiplied by to
obtain the secondary or tertiary units. The default is 0.453592, which is the conversion
factor for changing pounds to kilograms. See Section 10.10 on page 120 for a list of
multipliers.
To shift between primary, secondary, and tertiary units, press the UNITS key.
Rate of Change (ROC) Units Parameters
For applications using the ROC function, the primary scale should be configured with a finer resolution than the rate of change
(ROC) units to prevent a stepwise appearance in the ROC display. The ROC display step size (weight increment between
displayed values) can be roughly calculated as follows:
(updates_per_ROC_UNIT) * (PRIMARY_resolution / ROC_resolution)
For example, with INTERVL=30; REFRESH =0.1; UNITS=MIN; PRIMARY resolution at 0.1 LB and ROC resolution at 1.0
(LB/MIN):
-
INTERVL * REFRESH = 30 * 0.1 = 3.0 seconds per update (ROC data is flushed every 3.0 seconds)
-
With UNITS = MIN, there are 20 ROC data updates per ROC time unit: 60 seconds / 3.0 seconds per update
-
The resolution ratio of PRIMARY to ROC units is 0.1 (0.1 / 1.0)
-
This configuration provides a step size in the ROC display of 2 LB (2 LB increments between displayed values):
20 * 0.1 = 2
Note that setting both PRIMARY and ROC display resolutions to 1 LB would have resulted in a step size of 20 LB.

Description
Regulatory mode. Specifies the regulatory agency having jurisdiction over the scale site.
• OIML, NTEP, and CANADA modes allow a tare to be acquired at any weight greater
than zero. NONE allows tares to be acquired at any weight value.
• OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is
at no load. NONE allows tares to be cleared at any weight value.
• NTEP and OIML modes allow a new tare to be acquired even if a tare is already
present. In CANADA mode, the previous tare must be cleared before a new tare can be
acquired.
• NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net
mode as long as the current weight is within the specified ZRANGE. In OIML mode, the
scale must be in gross mode before it can be zeroed; pressing the ZERO key in net
mode clears the tare.
• INDUST provides a set of subparameters to allow customization of tare, clear, and print
functions in non-legal-for-trade scale installations. See Level 4 parameter descriptions
in Table 3-9 on page 47.
The value specified for this parameter affects the function of the front panel TARE and ZERO

FLDBUS Menu
The FLDBUS menu is shown only if a DeviceNet, Profibus, EtherNet/IP, or ControlNet option card is installed.
The SWAP parameter on the FLDBUS menu enables byte swapping by the iRite BusCommand handler rather
than requiring a SWP (SWAPBYTE) instruction in the PLC. Byte swapping is enabled by default for DeviceNet
cards; for all other fieldbus cards, byte swapping is disabled by default.
• BYTE swaps bytes within the word before transmission to the scanner
• WORD swaps words 1 and 2, 3 and 4, within a 4-word packet
• BOTH performs both operations, swapping bytes within a word and swapping words within the packet
• NONE disables swapping
The DATASIZE parameter sets the size of the BusCommand handler data transfers. The default value (8 bytes)
matches the default data size specified in the EDS and GSD files, and used by the standard discrete transfer
commands. DATASIZE can be set to any value from 2–128 bytes (1–64 words), but the value specified must
match the data size set for the PLC Scanner I/O data size.

Gravity compensation for latitude and elevation is available for the 920i. To calibrate with gravity compensation,
the LOCALE parameter under the FEATURE menu must be set ON, and the LATUDE (latitude) and ELEVAT
(elevation, in meters) parameters set before calibrating the indicator (see Figure 3-11 on page 42).
If the indicator is later installed at a different location, gravity compensation can be applied to a pre-calibrated
indicator by adjusting the LATUDE and ELEVAT parameters.

Figure 4-2. WZERO Calibration Display
To calibrate the indicator using the front panel, do the
following:
1. Place the indicator in setup mode (display
reads Scale Configuration ) and remove all
weight from the scale platform. If your test
weights require hooks or chains, place the
hooks or chains on the scale for zero
calibration.
2. With the SCALES menu highlighted, press the

calibrated. Press down again (GRADS
parameter highlighted), then press left to
highlight the CALIBR submenu (see
Figure 4-1). Press d o w n to go to zero
calibration ( WZERO ). See Figure 4-2 on
page 56.
3. Ensure scale is empty, then press down again
to show the current WZERO value, then press
the Calibrate softkey to calibrate zero. When
complete, the new A/D count for the zero
calibration is displayed. Press enter to save the
zero calibration value and go to the next
prompt (WVAL).
4. With WVAL displayed, press down to show the
stored calibration weight value. Use the
numeric keypad to enter the actual value of
the calibration test weights, then press enter to
save the value and go to span calibration
(WSPAN).
5. Place test weights on scale. Press down again
to show the current WSPAN value, then press
the Calibrate softkey to calibrate span. When
complete, the new A/D count for the span
calibration is displayed. Press enter again to
56
920i Installation Manual
save the span calibration value and go to the
next prompt (WLIN).
6. Five-point linearization (using the WLIN
parameter) provides increased scale accuracy
by calibrating the indicator at up to five
additional points between the zero and span
calibrations.
Linearization is optional: if you choose not to
perform linearization, skip the WLIN
parameter; if linearization values have
previously been entered, these values are reset
to zero during calibration. WZERO and
WSPAN must be calibrated before adding
linearization points; WLIN values must be
less than the WSPAN value and must not
duplicate WZERO or WSPAN.
To perform linearization, follow the
procedure below:
With WLIN displayed, Press down to go to the
first linearization point (POINT 1). Press down
again to show the weight value prompt (WGT
1), then down once more to show the weight
value. Place test weights on the scale, then use
the numeric keypad to enter the actual test
weight value. Press enter to save the value and
move to the calibration (CAL 1) prompt. Press
down to show the current calibration value,
then press the Calibrate softkey to calibrate the
linearization point. When complete, the A/D
count for the linear calibration is displayed.
Press enter again to save the calibration value
and go to the next prompt (POINT 2).
Repeat for up to five linearization points. To
exit the linearization parameters, press the up
key to return to WLIN.
7. The optional rezero function is used to
remove a calibration offset when hooks or
chains are used to hang the test weights.
NOTE: The rezero function cannot be used with
five-point linear calibration.
•
If no other apparatus was used to hang the
test weights during calibration, remove
the test weights and press up to return to
the CALIBR submenu.
• If hooks or chains were used during
calibration, remove these and the test
weights from the scale. With all weight
removed, go to the REZERO parameter,
then press down to show the current zero
value. Press the Calibrate softkey to adjust
the zero and span calibration values. Press
enter or up to return to the CALIBR
submenu.
8. Press up to return to the SCALES menu, or
press the Save and Exit softkey to exit setup
mode.

Serial Command Calibration
To calibrate the indicator using serial commands, the
indicator serial port must be connected to a terminal or
personal computer. See Section 2.3.3 on page 10 for
serial port pin assignments; see Section 9.0 on
page 89 for more information about using serial
commands.
Once the indicator is connected to the sending device,
do the following:
1. Place the indicator in setup mode (display
reads CONFIG) and remove all weight from the
scale platform. If your test weights require
hooks or chains, place the hooks or chains on
the scale for zero calibration.
2. Send the SC.WZERO#n serial command
(where n is the number of the scale) to
calibrate zero.
3. Place test weights on the scale and use the
SC.WVAL command to enter the test weight
value in the following format:
calibration or a multi-point linear calibration.
Click the Next button to continue.
Figure 4-3. iRev 4 Calibration Wizard
2. Next (see Figure 4-4), select the scale you
wish to calibrate.
SC.WVAL#n=vvvvv<CR>
4. Send the SC.WSPAN#n serial command to
calibrate span.
5. Up to five linearization points can be calibrated
between the zero and span calibration values.
Use the following commands to set and
calibrate a single linearization point:
SC.WLIN#n.V1=vvvvv<CR>
SC.WLIN#n.C1<CR>
The SC.WLIN#n.V1 command sets the test
weight value (vvvvv) for linearization point 1.
The SC.WLIN#n.C1 command calibrates the
point. Repeat using the SC.WLIN#n.Vx and
SC.WLIN#n.Cx commands as required for
additional linearization points.
6. To remove an offset value, clear all weight
from the scale, including hooks or chains used
to hang test weights, then send the
SC.REZERO#n serial command.
7. Send the KSAVEEXIT serial command to
save the calibration changes and exit setup
mode.

Configuring Scales
Once the hardware configuration has been set, scales
can be configured by selecting the parameter subsets
listed at the left side of the Hardware Configuration
display. For most applications, the Scales icon, under
System Parameters , should be configured first, by
associating each scale with an A/D channel or serial
scale source. To assign the scale source, double-click
on the scale number listed in the Scales menu (see
Figure 5-2), then select the scale source type in the
Config Scale dialog box.
When the setpoint view is set to a value greater than
one, swap and move icons are added to the toolbar,
allowing single or multiple setpoints to be reordered
(see Figure 5-3).
Figure 5-3. iRev 4 Setpoints Display
The Batching Wizard, available under the Tools menu
when viewing or changing setpoints, can be used to
set up a basic batch sequence, based on the batch type,
number of ingredients, and several batch options.
5.5

5.4.1
Configuring Other Parameters
Once the scale source is set, you can continue
configuring the scale using the other icons listed under
the System Parameters, or you can use the Scale Wizard
(shown as a button on the Scales menu; also available
under the Tools menu) to create a basic configuration
based on your application type, units, capacity, and
filtering requirements.
Other subsets of configuration parameters, including
stream, print, and display formatting, can be accessed
by selecting them from the list shown at the left side
of the iRev 4 displays.
5.4.2
Configuring the Display
The iRev 4 display editor allows the 920i display to be
customized by dragging and dropping widgets onto a
virtual display, then setting parameters specific to
each widget type. (See Section 9.2 on page 101 for
detailed information about widget programming.) Up
to ten display configurations can be saved for each
indicator file. Display configurations can be switched
within applications using custom programs to drive
the 920i.
Setpoints
The Setpoints menu, available by clicking the
Setpoints icon under System Parameters , provides
access to all configuration parameters for up to 100
setpoints. Configured setpoints can be displayed
individually or in groups of 5, 10, or 100; setpoint
parameters can be changed only when shown
individually. Click on the setpoint view icons in the
toolbar to change the view.

Connecting to the Indicator
Connect the PC serial port to port 2 of the 920i. Return
to the Hardware Configuration display, then click on
the Connect icon in the toolbar. iRev 4 attempts to
establish communications to the indicator.
Once communications is established, iRev 4 queries
the indicator configuration to determine whether the
indicator hardware matches the virtual hardware
configured in the current iRev 4 file. If the hardware
matches, the Hardware Configuration section of iRev
4 is disabled, preventing further changes.
If the hardware does not match, you are given the
option of either canceling the connect operation or
overwriting the iRev 4 hardware configuration with the
actual indicator hardware configuration.
5.6.1
Downloading to the Indicator
The Download Configuration function on the iRev 4
Communications menu allows an iRev 4 configuration
file (with or without scale calibration data), setpoint
data, widgets, database tables, or an iRite program file
to be downloaded to a connected indicator in setup
mode.
The D o w n l o a d C u r r e n t D i s p l a y f un c t i on o n t h e
Communications menu allows you to download only
the currently displayed object, such as the parameter
set for one scale of a multi-scale configuration.
Because less data is transferred using Download Current
Display, it is typically faster than a full configuration
download, but there is an increased possibility that the
download may fail due to dependencies on other
objects. If the download fails, try performing a
complete download using the Download Configuration
function.
A progress message is displayed during the download
indicating the progress of the download and also
during the clear memory indicating its progress.
5.6.2
Uploading Configuration to iRev
The Upload Configuration function on the iRev 4
Communications menu allows the existing
configuration of a connected indicator to be saved to a
file on the PC. Once saved, the configuration file
provides a backup that can be quickly restored to the
indicator if needed. Or, the file can be edited within
iRev 4, then downloaded back to the indicator.
NOTE: The indicator must be in setup mode before uploading
or downloading data.
5.7
Installing Software Upgrades
New releases of the 920i system software can be
downloaded and installed using an internet connection
and the Rice Lake Web Update application.
NOTE: Before upgrading to a new version of 920i system
software, ensure that a copy of the current indicator
configuration has been saved using iRev 4. Reloading the
system software requires a RESETCONFIGURATION
function and resets all configuration and calibration values
to their factory defaults.

Print Formatting
The 920i provides print formats that determine the format of the printed output when the PRINT key is pressed, a
KPRINT serial command is received, or when setpoint push-print or truck weigh-in or weigh-out operations are
performed. Supported print formats are: GFMT, NFMT, ACCFMT, SPFMT, TRWIN, TRWOUT, ALERT,
AUXFMT1—AUXFMT20, and AUDITFMT. Additionally, two header formats, HDRFMT1 and HDRFMT2,
can be inserted into any of the other ticket formats using the <H1> and <H2>formatting commands. The
particular ticket format used for a given print operation depends on the indicator configuration (see Table 6-3 on
page 64) and the particular operation performed.
Each print format can be customized to include up to 1000 characters of information, such as company name and
address, on printed tickets. You can use the iRev 4™ configuration utility, serial commands, or the indicator front
panel (PFORMT menu) to customize the print formats.
6.1
Print Formatting Commands
Table 6-1 lists commands you can use to format the 920i print formats. Commands included in the format strings
must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on the
ticket. Text characters can include any ASCII character that can be printed by the output device.

Customizing Print Formats
The following sections describe procedures for customizing print formats using the iRev 4 configuration utility,
serial commands, or the front panel (PFORMT menu. See Section 10.6 on page 112 for information about
custom stream formatting.
6.4.1
Using iRev
The iRev 4 configuration utility provides a ticket formatting grid with a tool bar. The grid allows you to construct
the ticket format without using the formatting commands (<NL> and <SP>) required by the front panel or serial
command methods. Using iRev 4, you can type text directly into the grid, then select weight value fields from the
tool bar and place them where you want them to appear on the printed ticket.
Figure 6-1 shows an example of the iRev 4 print formatting display.

6.4.2
Using the Front Panel
If you have no access to equipment for communication through a serial port or are working at a site where such
equipment cannot be used, you can use the PFORMT menu (see Figure 6-2 on page 66) to customize the print
formats.

920i Installation Manual
• To add a character: position the cursor in the format where you want to add the character. Use the up key to
return to the character selection list, use the navigation keys to highlight the character to add, then press
enter. The new character is added to the left of the current cursor location in the format string.
• To add a blank space to a string, position the cursor to the right of where the space is to be inserted in the
format string, highlight the SP character in the selection list, and press enter.
• To delete a character, position the cursor to the right of the character to be deleted from the format string,
then press the CLR key.
• To add a special character, insert the < and > delimiter characters from the selection list. Use the numeric
keypad to insert the decimal ASCII value (1–255) of the character between the delimiters. For example,
insert <2> to add the STX character to the print format.
To save the edited format string, position the cursor in the format string and press enter. Softkeys shown on the
character selection display provide additional functions:
Default
Restores the string to its default value.
Home
Positions cursor at the beginning of the format string.
Cancel
Exits without saving changes to the format string.
End
Positions cursor at the end of the format string.
Restore
Restores the string to its previously saved value.
A Print Test softkey is shown under the FMT parameter after exiting the character selection display. If a printer is
attached, this key can be used to verify the edited string format before exiting setup mode.
NOTE: The Print Test softkey is not available for the HDRFMTx formats. These formats can be output only when inserted into
one of the printable ticket formats by using the <H1> or <H2> print format commands.
6.4.3
Using Serial Commands
With a personal computer, terminal, or remote keyboard attached to one of the 920i serial ports, you can use the
serial command set described in Table 6-1 on page 62 to customize the print format strings.
To view the current setting of a format string, type the name of the print format and press the enter key. For
example, to check the current configuration of the GFMT format, type GFMT.FMT and press enter. The indicator
responds by sending the current configuration for the gross format:
GFMT.FMT=<G> GROSS<NL>
To change the format, use the GFMT.FMT or NFMT.FMT serial command followed by an equals sign (=) and
the modified print format string. For example, to add the name and address of a company to the gross format, you
could send the following serial command:
GFMT.FMT=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>
A ticket printed using this format might look like the following:
MOE'S DUMP
2356 EAST HIGHWAY ROAD
SMALLTOWN
1345 LB GROSS
The ticket above could also be formatted by specifying the company address information in the HDRFMT1
ticket format, then substituting the <H1> command for the address in the GFMT ticket format:
HDRFMT1=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2>
GFMT.FMT=<H1><G> GROSS<NL>

Using the Truck Modes
To select a truck in/out mode, press the setup switch to
enter setup mode. Use the navigation keys to go to the
FEATURE menu, then to the TRUCK submenu to
select the mode.
Next, go right to the SOFTKEYS submenu and
configure the Weigh In , Weigh Out , and Truck Regs
softkeys. These keys are required when using the
truck modes.
OFF
Table 7-1. Truck Mode Features
Stored IDs let you keep a database of truck IDs and
weigh-in weights in the indicator’s memory. The
indicator can automatically store up to 1000 truck IDs
and tares; or it can clear the information after printing
a weigh-out ticket. For example, if the same truck
seldom crosses the scale, it may not be practical to
save its ID number and weigh-in weight. However, if
that same truck crosses the scale many times each day,
it’s more convenient to store the information in the
indicator memory and recall it when needed. Stored
IDs and weights are available in modes 3, 4, 5, and 6.
Keyed tares allow you to manually enter the tare
weight using the numeric keypad and the TARE key.
Keyed tares are available in modes 1, 3, and 5. To use
keyed tares, an incoming truck must be empty at
weigh-in, full at weigh-out.
NOTE: Some local regulations require the tare weight
to be read from the scale. If so, don’t use the keyed
tares feature.
Value swapping ensures that the lowest of two weight
values associated with a particular ID number is used
as the tare weight. For example, if a truck crosses the
scale fully loaded at weigh-in, then unloads and
crosses the scale empty at weigh-out, the indicator
automatically assigns the lesser (empty truck) weight
as the tare. Value swapping is available in modes 1, 2,
3, and 4.
NOTE: In the OIML regulatory mode, modes 5 and 6
are not allowed to complete a transaction if the
outbound weight is greater than the inbound weight.
In this case, the indicator will display an error
message “Illegal Weighment” because a negative net
weight cannot be printed as a legal weight.

Single-Transaction Tare Weights
and IDs
One-time transactions are supported in all modes that
can be configured to use stored IDs (modes 3–6). This
function allows one-time weighing of trucks without
adding the truck ID and weigh-in weight to the
permanent truck register.
To use this function, press the Weigh In or Weigh Out
softkey, then enter a truck ID containing a decimal
point. IDs entered with a decimal point as part of the
ID are erased from the truck register when the
transaction is complete.
Weigh-In Procedure
In modes 1 and 2, the indicator erases truck ID
numbers and tare weights from memory after the
transaction. In modes 3–6,the truck ID and weigh-in
weight values are saved after the weigh-out ticket has
been processed.
The general weigh-in procedure is as follows:
1. The empty truck moves onto the scale for
weigh-in.
2. Press the Weigh In softkey.
3. A prompt is shown to enter the truck ID (up to
eight alphanumeric characters). Enter the ID,
then press the enter key.
4. Indicator generates the weigh-in ticket:
ID 304812
GROSS 15000. LB INBOUND
01/14/2002 10:24 AM
5. Truck leaves the scale.
7.4
Weigh-Out Procedure
The general weigh-out procedure is as follows:
1. The loaded truck moves onto the scale for
weigh-out.
2. If truck ID is known, press the Weigh Out
softkey, enter the ID, and press the enter key.
If ID is not known, press the Truck Regs
softkey to view list of stored IDs (see
Figure 7-2 on page 68). Scroll to the correct
truck ID, note the ID number, then press the
Cancel softkey to return to the weight display.
From the weight display, press Weigh Out, key
in the ID, then press the enter key.
3. Indicator generates the weigh-out ticket. In
modes 1 and 2, the ID is deleted once the
weigh-out ticket is processed.

Setpoints
The 920i indicator provides 100 configurable setpoints for control of both indicator and external equipment
functions. Setpoints can be configured to perform actions or functions based on specified parameter conditions.
Parameters associated with various setpoint kinds can, for example, be configured to perform functions (print,
tare, accumulate), to change the state of a digital output controlling indicator or external equipment functions, or
to make conditional decisions. NOTE: Weight-based setpoints are tripped by values specified in primary units
only.
8.1
Batch and Continuous Setpoints
920i setpoints can be either continuous or batch setpoints.
Continuous setpoints are free-running: the indicator constantly monitors the condition of free-running setpoints
at each A/D update. The specified setpoint action or function is performed when the designated setpoint
parameter conditions are met. A digital output or function assigned to a free-running setpoint continuously
changes state, becoming active or inactive, as defined by the setpoint parameters.
Batch setpoints are active one at a time, in an ordered sequence. The 920i can use setpoints to control up to 100
separate batch processing steps.
A digital output associated with a batch setpoint is active until the setpoint condition is met, then latched for
the remainder of the batch sequence.
To use batch setpoints, you must activate the BATCHNG parameter on the SETPTS menu. This parameter
defines whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, while
MANUAL sequences require a BATSTRT signal. The BATSTRT signal can be initiated by a digital input,
serial command, Batch Start softkey, or the StartBatch function in an iRite program.
For setpoint kinds that can be used as either continuous or batch setpoints, the BATCH parameter must also
be set ON. (Setpoint kinds that can only be used as batch setpoints do not require the BATCH parameter.) If
the setpoint is defined but the BATCH parameter is off, the setpoint operates as a continuous setpoint, even
during batch sequences.
NOTE: In applications that contain both batch setpoint routines and continuous setpoints, continuous setpoints
should be kept separate from the batch sequence. This is especially true when using CONCUR or TIMER
setpoints to perform actions or functions based on the batch sequence. CONCUR and TIMER setpoints should
not be included in the referenced START and END setpoint sequence.

–REL
Negative relative setpoint. Performs functions based on a specified value below
a referenced setpoint, using the same weight mode as the referenced setpoint.
X
X
%REL
Percent relative setpoint. Performs functions based on a specified percentage
of the target value of a referenced setpoint, using the same weight mode as the
referenced setpoint. The actual target value of the %REL setpoint is calculated
as a percentage of the target value of the referenced setpoint.
X
X
RESREL
Relative to a result setpoint. Performs functions based on a specified
percentage of the captured value of a referenced setpoint, using the same
weight mode as the referenced setpoint. The actual target value of the RESREL
setpoint is calculated as a percentage of the captured value of the referenced
setpoint, rather than the target value.
X
X
PAUSE
Pauses the batch sequence indefinitely. A BATSTRT signal must be initiated to
continue the batch process.
X
DELAY
Delays the batch sequence for a specified time. The length of the delay (in
tenths of a second) is specified on the VALUE parameter.
X
WAITSS
Wait for standstill. Suspends the batch sequence until the scale is at standstill.
X
COUNTER
Specifies the number of consecutive batch sequences to perform. Counter
setpoints should be placed at the beginning of a batch routine.
X
AUTOJOG
Automatically checks the previous weight-based setpoint to verify the setpoint
weight value is satisfied in a standstill condition. If the previous setpoint is not
satisfied when at standstill, the AUTOJOG setpoint activates the digital output
of the previous weight-based setpoint for a period of time, specified on the
VALUE parameter. The autojog process repeats until the previous weight-based
setpoint is satisfied when the scale is at standstill.
X
NOTE: The AUTOJOG digital output is typically used to signify that an autojog
operation is being performed. AUTOJOG should not be assigned to the same
digital output as the related weight-based setpoint.
COZ
Center of zero. Monitors for a gross zero condition. The digital output
associated with this setpoint kind is activated when the referenced scale is a
center of zero. No value is required for this setpoint.
X
INMOTON
In motion. Monitors for an in-motion condition. The digital output associated
with this setpoint is activated when the scale is not at standstill. No value is
required for this setpoint.
X
INRANGE
In range. Monitors for an in-range condition. The digital output associated with
this setpoint is activated when the scale is within capacity range. No value is
required for this setpoint.
X
BATCHPR
Batch processing signal. The digital output associated with this setpoint is
activated whenever a batch sequence is in progress. No value is required for
this setpoint.
X
TIMER
Tracks the progress of a batch sequence based on a timer.
X
The timer value, specified in tenths of a second on the VALUE parameter,
determines the length of time allowed between start and end setpoints. The
indicator START and END parameters are used to specify the start and end
setpoints. If the END setpoint is not reached before the timer expires, the digital
output associated with this setpoint is activated.

CONCUR
Description
Batch
Allows a digital output to remain active over a specified portion of the batch
sequence. Two types of concur setpoints can be configured:
Continuous
X
Type 1 (VALUE=0): The digital output associated with this setpoint becomes
active when the START setpoint becomes the current batch step and remains
active until the END setpoint becomes the current batch step.
Type 2 (VALUE > 0): If a non-zero value is specified for the VALUE parameter, that
value represents the timer, in tenths of a second, for this setpoint. The digital
output associated with this setpoint becomes active when the START setpoint
becomes the current batch step and remains active until the timer expires.
DIGIN
Digital input setpoint. Requires a specific group of digital inputs to be in low (0
VDC) state to satisfy the setpoint. The digital output associated with this
setpoint is held in a low (0 VDC) state until the inputs selected for the digital
input mask are all in a low state.
X
AVG
Average setpoint. Performs functions based on the calculated average weight
over a specified number of A/D samples.
X
X
Note that this setpoint is based on the raw A/D weight value, rather than the
rounded value shown on the indicator display. For example, if the display shows
50.0 but the actual raw A/D value is 49.99, the setpoint will not be satisfied.
TOD
Time of day setpoint. Performs functions when the internal clock time of the
indicator matches the specified setpoint time.
X
DELTA
Delta weight setpoint. Satisfied when the change in weight on the scale is equal
to or exceeds the absolute value specified for the setpoint.
X
CHKWEI
Checkweigher setpoint. Allows specification of over- and under-weight values.
Up to three digital outputs can be configured to represent overweight,
underweight, and accept conditions.
PLSCNT
Pulse counter setpoint. Performs functions based on pulse counts received by
a pulse input card.
PLSRAT
Pulse rate setpoint. Performs functions based on the pulse rate received by a
pulse input card.
ALWAYS
Always setpoint. This setpoint is always satisfied. It is typically used to provide
an endpoint for true/false branching batch routines.
X
NEVER
Never setpoint. This setpoint is never satisfied. It is used to branch to a
designated setpoint in true/false branching batch routines in which the batch
will not continue through the normal sequence of batch setpoints.
X
DINCNT
Digital input count setpoint. Counts pulses received at the specified digital
input.

Setpoint value.
• For weight-based setpoints: Specifies the target weight value, 0–9999999.
• For time-based setpoints: Specifies, in 0.1-second intervals, a time value in the
range 0–65535.
• For COUNTER setpoints: Specifies the number of consecutive batches to be run,
0–65535.
• For PLSCNT setpoints, specifies a number of pulses, 0–9999999, received by a
pulse input card.
• For PLSRAT setpoints, specifies a pulse rate in Hz, 0-65535, received by a pulse
input card.
TRIP
HIGHER
LOWER
INBAND
OUTBAND
Specifies whether the setpoint is satisfied when the weight is higher or lower than the
setpoint value, within a band established around the value, or outside of that band.
BANDVAL
0–9999999
For setpoints with TRIP=INBAND or OUTBAND, specifies a weight equal to half the
band width. The band established around the setpoint value is VALUE ±BANDVAL.
HYSTER
0–9999999
Specifies a band around the setpoint value that must be exceeded before the
setpoint, once off, can trip on again.
PREACT
OFF
ON
LEARN
FLOW
Allows the digital output associated with a setpoint to shut off before the setpoint is
satisfied to allow for material in suspension.
The ON value adjusts the setpoint trip value up or down (depending on the TRIP
parameter setting) from the setpoint value using a fixed value specified on the
PREVAL parameter.
The LEARN value can be used to automatically adjust the preact value after each
batch. LEARN compares the actual weight at standstill to the target setpoint value,
then adjusts the preact PREVAL by the PREADJ value times the difference after each
batch.
FLOW preact provides dynamic compensation for material flow rate in determining
when to shut off the digital output. Rather than waiting for the specified weight to be
reached, FLOW preact uses the change in weight over time to anticipate when the
TRIP minus PREACT weight value will be reached.
PREVAL
0–9999999
Specifies the preact value for setpoints with PREACT set to ON, LEARN, or FLOW.
Depending on the TRIP setting specified for the setpoint, the setpoint trip value is
adjusted up or down by the PREVAL value.
PREADJ
0.500000
0–9999999
Preact adjustment factor. For setpoints with PREACT set to LEARN, specifies a
decimal representation of the percentage of error correction applied (0.5 = 50%, 1.0
= 100%) each time a PREACT adjustment is made.
PRESTAB
0
0–65535
Preact stabilization time-out. For setpoints with PREACT set to LEARN, specifies the
time, in 0.1-second intervals, to wait for standstill before adjusting the PREACT
value. Setting this parameter to a value greater than zero disables the learn process if
standstill is not achieved in the specified interval.
PCOUNT
1
0–65535
Preact learn interval. For setpoints with PREACT set to LEARN, specifies the number
of batches after which the preact value is recalculated. The default value, 1,
recalculates the preact value after every batch cycle.
In a batch sequence with TRIP=HIGHER, the associated digital output is active until
the setpoint value is reached or exceeded; with TRIP=LOWER, the output is active
until the weight goes below the setpoint value.

Description
TOLBAND
0
0–9999999
Tolerance band. For setpoints with TRIP set to HIGHER or LOWER, specifies a
tolerance band around the target weight. If the captured weight is not within the
specified tolerance band, the preact learn function is not applied and the batch is
paused (based on the value of the TOLCNT parameter, below) until restarted or
reset.
TOLCNT
1
0–65535
Tolerance count. For setpoints with TRIP set to HIGHER or LOWER, specifies the
number of consecutive batch cycles in which the tolerance band (TOLBAND
parameter) must be exceeded before the batch process is paused. When the
specified value is met, the batch is paused and an error message is displayed. The
batch must be restarted or reset to clear the error message. The special value of zero
means that the batch is never paused for an out-of-tolerance condition.
RELNUM
1–100
For relative setpoints, specifies the number of the relative setpoint. The target weight
for this setpoint is determined as follows:
• For +REL setpoints, the value of the relative setpoint plus the value (VALUE
parameter) of the +REL setpoint
• For –REL setpoints, the value of the relative setpoint minus the value of the –REL
setpoint
• For %REL setpoints, the percentage (specified on the VALUE parameter of the
%REL setpoint) of the target value of the relative setpoint
• For RESREL setpoints, the percentage (specified on the VALUE parameter of the
RESREL setpoint) of the captured value of the relative setpoint

Warning
To prevent personal injury and equipment
damage, software-based interrupts must
always be supplemented by emergency stop
switches and other safety devices necessary
for the application.
If no digital input is assigned to
BATRUN, batching proceeds as if
BATRUN were always on: the batch will
start when the 3-way switch is turned to RUN, but the STOP
mushroom button will not function.
GND
Display or change assigned setpoints.
Batch Start
Starts batch process.
Batch Pause Pauses an active batch and turns off
all digital outputs except those
associated with concurrent and timer
setpoints. Processing is suspended
until Batch Start is pressed again.
Pressing Batch Start resumes the
batch and re-energizes all digital
outputs turned off by the Batch Pause.
Batch Reset Stops and resets an active batch to the
beginning of the process.
Batch Stop
Stops an active batch and turns off all
associated digital outputs.
Setpoint
When configuration is complete, exit setup mode.
Initialize the batch by turning the 3-way switch to
ABORT, then unlock the STOP button (the STOP
button must be in the OUT position to allow the batch
process to run). The batching switch is now ready to
use.

To begin a batch process, turn the 3-way switch to
START momentarily. If the STOP button is pushed
during the batch process, the process halts and the
button locks in the IN position.
The START switch is ignored while the STOP button is
locked in the IN position. The STOP button must be
turned counterclockwise to unlock it, then released
into the OUT position to enable the 3-way switch.
To restart an interrupted batch from the step where it
left off, do the following:
1. Unlock STOP button (OUT position)
2. Turn 3-way switch to START
To restart an interrupted batch from the first batch
step, do the following:
1. Turn 3-way switch to ABORT
2. Unlock STOP button (OUT position)
3. Turn 3-way switch to START
NOTE: Use this procedure (or the BATRESET serial
command) to initialize the new batch routine
following any change to the setpoint configuration.

Batching Examples
Example 1
The following example is used to dispense 100-LB
drafts, automatically refilling a hopper to 1000 LB
gross weight once the gross weight has dropped below
300 LB.
Setpoint 1 ensures that the hopper has enough material
to start the batch. If the hopper weight is 100 LB or
higher, setpoint 1 is tripped.
SETPOINT=1
KIND=GROSS
VALUE=100
TRIP=HIGHER
BATCH=ON
ALARM=ON
Setpoint 2 waits for standstill, performs a tare, and
puts the indicator into net mode.
SETPOINT=2
KIND=WAITSS
PSHTARE=ON
Setpoint 3 is used as a reference (relative setpoint) for
setpoint 4.
SETPOINT=3
KIND=NET
VALUE=0
TRIP=HIGHER
BATCH=OFF
Setpoint 4 is used to dispense material from the
hopper. When the hopper weight goes below 100 LB
net the setpoint is tripped.
SETPOINT=4
KIND=–REL
VALUE=100
TRIP=LOW
BATCH=ON
DIGOUT=1
RELNUM=3
Setpoint 5 is used to evaluate the gross weight of
material in the hopper after dispensing. When the
hopper weight falls below 300 LB, digital output 2
becomes active and the hopper is refilled to 1000 LB.
SETPOINT=5
KIND=GROSS
VALUE=300
TRIP=HIGHER
HYSTER=700
BATCH=ON
DIGOUT=2
Setpoint 6 is used as a “no flow alarm”. If the process
in setpoint 4 is not completed in 10 seconds, digital
output 4 becomes active to signify a problem.
SETPOINT=6
KIND=TIMER
VALUE=100
START=4
END=5
DIGOUT=4
Example 2
The following example uses a CONCUR setpoint to
provide a two-speed simultaneous fill of a hopper to a
net weight of 1000 LB.
Setpoint 1 ensures that the gross weight is within 50
LB of gross zero.
SETPOINT=1
KIND=GROSS
VALUE=0
TRIP=INBAND
BANDVAL=50
BATCH=ON
Setpoint 2 performs a tare once the scale is at
standstill.
SETPOINT=2
KIND=WAITSS
PSHTARE=ON
Setpoints

Setpoint 3 uses DIGOUT 1 to fill a hopper to a net
weight of 800 LB.
SETPOINT=3
KIND=NET

Serial Commands
The 920i indicator can be controlled by a personal
computer or remote keyboard connected to an
indicator serial port. Control is provided by a set of
serial commands that can simulate front panel key
press functions, display and change setup parameters,
and perform reporting functions. The serial commands
provide the capability to print configuration data or to
save that data to an attached personal computer. This
section describes the serial command set and
procedures for saving and transferring data using the
serial ports.
9.1
The Serial Command Set
The serial command set can be divided into five
groups: key press commands, reporting commands,
the RESETCONFIGURATION special function
command, parameter setting commands, and transmit
weight data commands.
When the indicator processes a serial command, it
responds with the message OK . The OK response
verifies that the command was received and has been
executed. If the command is unrecognized or cannot
be executed, the indicator responds with ??.
9.1.1
Key Press Commands
Key press serial commands (see Table 9-1) simulate
pressing the keys on the front panel of the indicator.
These commands can be used in both setup and
normal (weighing) mode. Several of the commands
serve as “pseudo” keys, providing functions that are
not represented by a key on the front panel.
For example, to enter a 15-pound tare weight using
serial commands:
1. Type K1 and press ENTER (or RETURN).
2. Type K5 and press ENTER.
3. Type KTARE and press ENTER.

Clear and Reset Commands
SC.MOTBAND#1=5D<ENTER>
The following commands can be used to clear and
reset the 920i:
PCLR : Program clear. Erases the loaded user
program (setup mode only).
RS : Reset system. Resets the indicator without
resetting the configuration.
RESETCONFIGURATION: Restores all configuration
parameters to their default values (setup mode
only). The RESETCONFIGURATION function can
also be initiated by pressing the Reset Config
softkey under the VERSION menu. Use the up
key to select Clear entire indicator configuration, then
press ENTER to reset the indicator.
Command
SC.SRC#n
Parameter Setting Commands
Parameter setting commands allow you to display or
change the current value for a particular configuration
parameter (Tables 9-3 through 9-12).
Current configuration parameter settings can be
displayed in either setup mode or normal mode using
the following syntax: command<ENTER>
Most parameter values can be changed in setup mode
only; setpoint parameters listed in Table 9-6 on
page 95 can be changed when in normal weighing
mode.
Use the following command syntax when changing
parameter values: command=value<ENTER>, where value
is either a number or a parameter value. Use no spaces
before or after the equal (=) sign. If you type an
incorrect command, the display reads ??.
For example, to set the motion band parameter on
Scale #1 to 5 divisions, type the following:
For parameters with selectable values, enter the
command and equal sign followed by a question
mark: command=?<ENTER> to see a list of those values.
The indicator must be in setup mode to use this
function.
NOTE: Some parameters are valid only if other parameters or
parameter values are specified. See the configuration menus
in Section 3.2 on page 25 for information about parameter
dependencies. Restrictions for front-panel configuration also
apply to serial command configuration.

Database Commands
The commands listed in Table 9-14 can be used to
create and maintain databases in the 920i. Except for
the D B . D E L A L L command, all of the database
commands require an extension to identify the number
of the database within the memory card and the slot
number of the memory card.
Command
Description
DB.ALIAS.n#x
Get or set database name
DB.CLEAR.n#x
Clear database contents
DB.DATA.n#x
Get or set database contents
DB.SCHEMA.n#x Get or set database structure
DB.DELALL
Delete all databases and database
contents
n represents the database number within the memory card;
x is the slot number of the memory card.
Each command must be terminated with a carriage return
character (<CR>, ASCII 13).
Table 9-14. Database Commands
DB.ALIAS
The DB.ALIAS command is used to get or set the alias
used by iRite programs to reference the specified
database. Each database alias must be unique among
all databases and adhere to the following rules: 8
character maximum; must begin with an alpha
character or an underscore; can only contain A–Z,
a–z, 0–9, or an underscore (_).
Example. The following command assigns an alias of
TRUCKS_2 to the first database on the memory card
installed in slot 2:
DB.CLEAR
To clear the contents of a database, send the following
command:
DB.CLEAR.n#x<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
The 920i responds with OK<CR> if the command is
successful, ??<CR> if unsuccessful.
DB.DATA
The DB.DATA command can be used to send data to or
retrieve data from the 920i.
Data can be sent to the indicator using the following
command:
DB.DATA.n#x = data{ | }<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
data represents a single cell of a row of data
{ | } is a pipe character (ASCII 124), used to
delimit cell data. If the data being sent is not the
last cell of the row, append the pipe character to
the data to indicate that more data is coming for
that particular row. If the data being sent is the last
cell of the row, do not append the pipe character.
If the command is accepted, the 920i responds with
OK<CR>; if not, it responds with ??<CR>.
DB.ALIAS.1#2=TRUCKS_2<CR>
Sending the DB.ALIAS command alone, without
assigned data, returns the current database alias.
Serial Commands
99
Example. The following commands place the data
shown in Table 9-15 into the first database in the
onboard memory:
The 920i responds to the command above by returning
the following:
<Max Records>,<Current Record Count>,
<Column Name>,<Data Type>,<Data Size>,...<CR>
DB.DATA.1#0=aaa|<CR>
DB.DATA.1#0=bbb|<CR>
DB.DATA.1#0=ccc|<CR>
DB.DATA.1#0=ddd<CR>
The <Column Name>, <Data Type>, and <Data Size>
elements repeat for each column in the database.
The <Column Name> follows the rules for alias
names: 8 character maximum; must begin with an
alpha character or an underscore; can only contain
A–Z, a–z, 0–9, or an underscore (_).
The <Data Type> is represented by a numeric field:
Cell
1
The DB.SCHEMA command is used to get or set the
structure of a database.
DB.SCHEMA.n#x<CR>
DB.DATA.1#0=this|<CR>
DB.DATA.1#0=is|<CR>
DB.DATA.1#0=a|<CR>

DB.DATA.n#x<CR>
The 920i responds with the entire contents of the
database. Returned data is cell-delimited with the pipe
character (ASCII 124) and row-delimited with
carriage returns (ASCII 13).
For example, the following command could be used to
return the contents of database 1 in the onboard
memory:
Table 9-16. Data Type Field Codes
The <Data Size> value must match the data type. A
range of data size values is allowed only for the
string data types:
Size
DB.DATA.1#0<CR>
If the database contents are the records shown in
Table 9-15, the indicator responds with the following
data, using pipe characters and carriage returns to
delimit the database cells and rows, respectively:
this| is| a| test<CR>aaa| bbb|ccc|ddd<CR>
NOTE: There is no end of database notification at the end of
the DB.DATA command transmission. Use a receive
time-out to determine command completion. The time-out
value will vary based on baud rate.
You should determine the number of records currently
in the database both prior to and after sending the
DB.DATA command to verify that the correct number
of records are received. The number of records can be
determined with the DB.SCHEMA command.
NOTE: The 62K of onboard (slot 0) memory can be allocated
to up to eight auxiliary databases. However, the size of any
one database may limit the size and number of other
databases.

9.2
Widget Programming
9.2.1
The type and location of elements shown on the 920i
display are easily specified using the drag and drop
features of the iRev 4 utility. However, display widgets
can also be programmed using serial commands while
the 920i is in setup mode, or through iRite
programming. Up to ten different screens can be
configured.
Serial command widget programming is
accomplished in setup mode, using the WDGT serial
command. The first parameter specified is the widget
type, listed in Table 9-18. The following sections
describe each of the widget types and the parameters
and values specific to that type.
In setup mode, the WDGT.CLR serial command can
be used to clear all specified widgets from the display.

Scale Widgets
Scale widgets are used to present basic scale data from
one or more configured scales. For multiple scale
applications, up to four scale widgets can be
configured to be shown on the display at any one time.
Fewer displayed widgets allow each widget to be
larger. Scale data from additional configured scales
can be shown by scrolling up or down through all
configured scales, including a total scale widget, if
configured.

location 30,30 (near upper left corner of display).
9.2.3
Bargraph Widgets
Bargraph widgets allow display of vertical or
horizontal graphs, either a normal bargraph style or a
needle gauge, with or without graduations. The graph
can be used to represent scale weight or progress
toward a setpoint target value.

Example:
WDGT#2=6,120,120,6,Alarm, 4,12,1,1,2<CR>
creates a visible symbol widget for screen 2, named
Alarm, using the bell symbol (symbol widget number
6 in Table 9-19 on page 104), with the upper left-hand
corner of the label at pixel location 120,120. The
symbol toggles on or off depending on the state of bit
1 on digital I/O expansion card 12.
NOTE: For symbol widgets associated with setpoint
digital outputs, the widget is set to state 1 (see
Table 9-19) when the setpoint is tripped, but the state
of the digital output depends on the type of setpoint.
Batch setpoints: When tripped, the associated digital
output is set inactive (widget set to state 1)
Continuous setpoints: When tripped, the associated
digital output is set active (widget set to state 1)

10.1 Troubleshooting
Table 10-1 lists general troubleshooting tips for various hardware and software error conditions. See the
following pages for additional information about specific diagnostic tools. Additionally, the CPU board has
diagnostic LEDs that flash when sending/receiving data, and a heartbeat LED for troubleshooting.
Symptom
Cause/Remedy
Possible blown fuse or bad power supply. Check fuses (see Section 2.8 on
page 16) and replace if necessary. Fuse specifications are listed on page 127; fuse
replacement part numbers are listed in Table 2-8 on page 18.
Indicator does not power up
If fuses are good, check all voltages on CPU board. Power supply should output
both +6V and –6V levels to the CPU board (see Figure 2-6 on page 12). If power
supply appears bad, check the small glass fuse (2.5A, 5x20mm PN85791) on the
power supply board.
Front panel power indicator blinking (

920i Installation Manual
10.1.1
Option Card Diagnostic Errors
Option cards are detected by the 920i at power-up. If
the current indicator configuration requires an option
card but that card is not detected at power-up, an error
similar to the following is displayed:
HARDWARE CRITICAL TO PROPER OPERATION
WITH CURRENT CONFIGURATION
CANNOT BE FOUND
A/D SLOT 4 CHANNEL 1
INSTALL HARDWARE OR RECONFIGURE
To recover from this error you can do the following:
• If the option is required, ensure that the card is
properly seated in its slot and cycle the power. If
the card is still not recognized, replace the card
or try installing the card in a different slot.
• Enter setup mode and reconfigure to eliminate
the requirement for the option.
• Go to the VERSION menu and use the Reset
Config softkey (or RESETCONFIGURATION
command) to perform a configuration reset.
Configuration reset returns all configuration
values to their factory defaults.
See Section 10.1.2 below, for information about using
the HARDWARE serial command to verify that
installed cards are recognized.
10.1.2
Using the HARDWARE Command
The HARDWARE serial command can be issued to
verify that all installed cards are recognized by the
system. The HARDWARE command returns a string
of card type codes, representing cards installed in slots
1–14:
HARDWARE=3,3,2,4,5,0,0,0,0,0,0,0,0,0

NOTE: Code 11 is returned only by the EtherNet/IP card.
The standard 10M/100Mbps Ethernet card does not return
a card type code. Any slot containing a standard Ethernet
card will return a value of 0 on the HARDWARE command.
Table 10-2. HARDWARE Command Option Card Codes
If an installed card is not recognized (HARDWARE
command returns a code of 0 for that slot), ensure that
the card is seated properly. Reinstall the card, if
necessary, then cycle the indicator power to read the
configuration again. If the card is still not recognized,
try installing it in another slot.
User Program Diagnostic Errors
Faulty user programs can cause critical errors that are
detected by the 920i at power-up. The following error
message is caused by a user program attempting to
divide by zero:
A CRITICAL USER PROGRAM ERROR
HAS BEEN DETECTED
DIVIDE BY ZERO
SYSTEM RESET IS REQUIRED
To recover from this error you can do the following:
• Cycle the indicator power to reset the user
program.
• Correct the iRite program to eliminate the divide
by zero operation. Recompile the program, then
download the corrected program to the indicator.
If technical assistance is required, contact RLWS
technical support.
Diagnostic Boot Procedure
If a user program causes an error in the start-up
handler, press and hold the setup switch while cycling
power to the 920i to place the indicator in setup mode.
Use iRev 4 monitor mode to send the PCLR command
erase clear the user program.
If the error is still not cleared, perform the following
diagnostic boot procedure.
1. Disconnect power to the 920i.
2. Connect the serial port of a PC with iRev 4
installed to port 2 of the 920i. Connection must
be made at 38400 bps.
3. Open the indicator enclosure and place a jumper
across the SW1 boot mode pins (see Figure 2-6
on page 12).
4. Power up the 920i. The indicator will stall at the
diagnostic monitor.
Appendix
107
5. Start iRev 4 and enter monitor mode, then type
BOOT.
6. Use the indicator setup switch to enter setup
mode.
7. Remove the jumper from SW1.
10.1.4
8. From monitor mode, enter the
RESETCONFIGURATION command.
Determine the cause of the startup handler error, make
program corrections, then reload the corrected user
program and test.
Using the XE Serial Command
The XE serial command can be used to remotely query the 920i for the error conditions shown on the front panel.
The XE command returns a decimal number representing any existing error conditions. For multi-scale
applications, the value returned by the XE command represents all error conditions, if any, present on all
configured scales.
If more than one error condition exists, the number returned is the sum of the values representing the error
conditions (see Table 10-3 on page 108). For example, if both a tare error (TAREERR, 65536) and a truck
database checksum error (ETRUCKERR, 8192) have occurred, the XE command returns the value 73728,
representing the sum of those two error conditions.

10.3 PS/2 Keyboard Interface
Serial port 2 on the 920i CPU board provides a
PS/2-type keyboard interface for use with a remote
keyboard. To use the keyboard interface, set the
INPUT parameter for Port 2 (under the SERIAL
menu) to KEYBD.
Table 10-6 summarizes the 920i-specific functions
provided by the keyboard interface; most other
alphanumeric and navigational keys provide functions
equivalent to those typical for PC operation. Menu
parameters and serial commands that affect indicator
keypad operation (including the KBDLCK,
ZERONLY, and KLOCK serial commands) also affect
the remote keyboard.
NOTES:
•
•
The keyboard interface is not hot-pluggable.
Disconnect power to the 920i before plugging
the keyboard cable into the Port 2 connector.
The 920i supports keyboard scan codes 1, 2,
and 3.

10.4 Serial Scale Interface
Serial ports 3 through 32 can be configured for serial
scale input. The serial scale function allows other
scale indicators to send gross, net, or tare weight data
to the 920i. Once a serial port has been configured to
accept scale data, the data format can be customized
to match the data stream sent by that indicator.
To configure a serial scale, do the following:
1. Under the SERIAL menu, set the INPUT
parameter for the selected port to SCALE
(legal-for-trade serial scale) or INDUST
(industrial serial scale).
2. Return to the SCALES menu. Under CONFIG,
drop down and select the serial port. If the serial
scale is not shown, press the Change Type
softkey to select available serial scales, then use
the navigational keys to select the serial scale.
Press Add to move the scale to the righthand
column, the press Done.
3. Under the SERIAL menu, return to the selected
port and set the format under the SFMT
parameter to match the format sent by the serial
scale.
The default serial scale format is:
<2><P><W7.><U><M><S><CR><LF>
where:
<2>
<P>
<W7.>
<M>
<U>
<S>
<CR>
<LF>
STX character
Polarity
Seven characters of net data with decimal point
Mode
Units
Status

Line feed
NOTE: Industrial serial scales (INDUST) do not require
the <M>, <U>, and <S> identifiers. However, the units and
number of decimal places must be specified. Units can
be selected from the FORMAT menu; decimal places
should be indicated on the w-spec identifier. For
example, a seven-digit weight requiring two decimal
places should be specified as <W7.2> rather than <W7.>.
See Section 10.6 for more information about stream
formatting and format identifiers.
iRev 4 provides several preset scale formats within its
Stream Formatting function. Figure 10-1 shows one of
the iRev 4 stream formatting displays.
Figure 10-1. iRev 4 Stream Formatting Display
10.5 Local/Remote Operation
For truck scale and similar applications, local/remote
support provides function equivalent to that of a
legal-for-trade remote display with keypad. Scale data
from the local indicator is also displayed at the remote
unit, and keypad input from the remote allows transactions
to be initiated from either the local or remote unit.
To configure for local/remote operation, first set up
the local scale (including softkey assignments, truck
mode, and database information, as required). Use the
SERIAL menu, serial commands, or iRev 4 to set the
Local Unit serial parameters shown in Table 10-7.
Configure the remote indicator using the serial
parameters listed for the Remote Unit.

10.6 Custom Stream Formatting
Each port can be independently configured to stream a default frame format or can be customized to stream a
user-defined format. Custom formatting is very similar to the standard print formatting described in Section 6.0.
Table 10-8 on page 112 lists the format identifiers used to configure a custom stream format. See Section 10.7 on
page 115 for examples of custom stream formats.

10.8 Data Formats
Continuous Output Serial Data Format
If continuous transmission is configured for a serial
port (STREAM parameter set to LFT or INDUST on
the SERIAL menu), the 920i sends data using the
Consolidated Controls serial data format shown in
Figure 10-2:
<STX> <POL> <wwwwwww> <UNIT> <G/N> <S> <TERM>
ASCII 02
decimal
G = Gross
N = Net
Polarity:
<space> = Positive
<–> = Negative
Weight: 7 digits, right-justified, dummy
zeroes, decimal point with no leading
zeroes except for leading zero immediately
preceding the decimal point. Leading
zeroes transmitted as spaces.
L = pounds
K = kilograms
T = tons
G = grains
<space> = grams
O = ounces
<CR> <LF>
or <CR>
Status:
<space> = valid
I = Invalid
M = Motion
O = Over/under range
Figure 10-2. Continuous Output Serial Data Format
Demand Output Serial Data Format
When demand mode is configured for the serial port
(STREAM parameter set to OFF), the 920i uses a data
string formatted for a basic ticket printout. The
particular ticket format printed depends on the
indicator configuration.
You can customize the ticket to work with a wide
variety of printers, scoreboard displays, and other
remote equipment. See Section 6.0 on page 62 for
more information on custom print formats.
RS-485 Data Formats
Two-wire RS-485 communications is available on
p o r t 4 o f t h e C P U b o a r d ; f o u r- w i r e R S - 4 8 5
communications is supported on the “A” ports of any
installed serial expansion cards.
The 920i has a built-in RS-485 software protocol
which is enabled when you assign a non-zero address
to the indicator. Valid RS-485 addresses must be in the
range 1–255; the address is specified on the
ADDRESS parameter on the SERIAL menu.
All remote commands are initiated using the data
format shown in Figure 10-3:
<STX> <ADDRESS> <COMMAND> <CR>
ASCII 02
decimal
EDP serial command
Address of the
receiving indicator
ASCII
13 decimal
NOTE: Host must send <CR>, not
<CR><LF>. Failure to use <CR>
renders all indicators unable to
respond to serial commands
Figure 10-3. RS-485 Send Data Format

920i Installation Manual
If the initiating device address matches the port address
of an 920i on the RS-485 network, that indicator
responds. For example, with demand outputs, or in
response to an XG#1 command, the responding
indicator uses the format shown in Figure 10-4:
<STX> <ADDRESS> <DEMAND DATA> <ETX> <CR>
ASCII 02

Address of the
transmitting indicator
Response commands from
indicator:
<first line > <EOL>
<additional lines > <EOL>

where EOL = <CR> or <CR> <LF>
(set by TERMIN parameter on the
SERIAL menu)
ASCII 13
decimal
ASCII 03

Figure 10-4. RS-485 Respond Data Format
Example: To send the XG#1 command from an ASCII
terminal to an indicator at address 65 (decimal) on the
RS-485 network, use the format shown in
Figure 10-3.
• The keyboard equivalent for the start-of-text
(STX) character is CONTROL-B.
• The indicator address (65) is represented by an
upper case “A”.
• The carriage return (CR) character is generated
by pressing the ENTER key.
Therefore, to send the XG#1 command to the
indicator at address 65, enter the following at the
terminal: <CONTROL-B>AXG#1.
The indicator responds with the format shown in
Figure 10-4:
1234.00 lb
10.9 Digital Filtering
Standard digital filtering uses mathematical averaging
to eliminate the variant digital readings that the A/D
converter sends periodically because of external
vibration. Digital filtering does not affect the indicator
measurement rate, but does affect the settling time.
The selections from 1 to 256 reflect the number of
readings averaged per update period. When a reading
is encountered that is outside a predetermined band,
the averaging is overridden, and the display jumps
directly to the new value.
DIGFLTx Parameters
The first three digital filtering parameters, DIGFLT1,
DIGFLT2, and DIGFLT3, are configurable filter
stages that control the effect of a single A/D reading
on the displayed weight. The value assigned to each
parameter sets the number of readings received from
the preceding filter stage before averaging.
A rolling average is passed to successive filters for an
overall filtering effect that is effectively a weighted
average of the product of the values assigned to the
filter stages (DIGFLT1 x DIGFLT2 x DIGFLT3) within a time
frame corresponding to the sum of the values (DIGFLT1
+ DIGFLT2 + DIGFLT3).
Setting the filters to 1 effectively disables digital
filtering.
RATTLETRAP® Filtering
R AT T L E T R A P d i g i t a l f i l t e r i n g ( R AT T R A P
parameter set ON) uses a vibration-dampening
algorithm to provide a combination of the best
features of analog and digital filtering. The
RATTLETRAP algorithm evaluates the frequency of
a repeating vibration then derives a composite
displayed weight equal to the actual weight on the
scale less the vibration-induced flaws. It is
particularly effective for eliminating vibration effects
or mechanical interference from nearby machinery.
Using RATTLETRAP filtering can eliminate much
more mechanical vibration than standard digital
filtering, but will usually increase settling time over
standard digital filtering.
DFSENS and DFTHRH Parameters
The digital filter can be used by itself to eliminate
vibration effects, but heavy filtering also increases
settling time. The DFSENS (digital filter sensitivity)
and DFTHRH (digital filter threshold) parameters can
be used to temporarily override filter averaging and
improve settling time:
•
•
DFSENS specifies the number of consecutive
scale readings that must fall outside the filter
threshold (DFTHRH) before digital filtering
is suspended.
DFTHRH sets a threshold value, in display
divisions. When a specified number of
consecutive scale readings (DFSENS) fall
outside of this threshold, digital filtering is
suspended. Set DFTHRH to NONE to turn off
the filter override.
Setting the Digital Filter Parameters
Fine-tuning the digital filter parameters greatly
improves indicator performance in heavy-vibration
environments. Use the following procedure to
determine vibration effects on the scale and optimize
the digital filtering configuration.
1. In setup mode, set the digital filter parameters
(DIGFLT1–DIGFLT3) to 1. Set DFTHRH to
NONE. Return indicator to normal mode.
2. Remove all weight from the scale, then watch
the indicator display to determine the
magnitude of vibration effects on the scale.
Record the weight below which all but a few
readings fall. This value is used to calculate
the DFTHRH parameter value in Step 4.
For example, if a heavy-capacity scale (10000
x 5 lb) produces vibration-related readings of
up to 50 lb, with occasional spikes to 75 lb,
record 50 lb as the threshold weight value.
3. Place the indicator in setup mode and set the
DIGFLTx paramete rs to eliminate th e
vibration effects on the scale. (Leave
DFTHRH set to NONE.) Find the lowest
effective value for the DIGFLTx parameters.
4. Calculate the DFTHRH parameter value by
converting the weight value recorded in Step
2 to display divisions:
threshold_weight_value / display_divisions
In the example in Step 2, with a threshold
weight value of 50 lb and a display divisions
value of 5 lb: 50 / 5 = 10. DFTHRH should be
set to 10D for this example.
5. Finally, set the DFSENS parameter high
enough to ignore transient peaks. Longer
transients (typically caused by lower vibration
frequencies) will cause more consecutive
out-of-band readings, so DFSENS should be
set higher to counter low frequency transients.
Reconfigure as necessary to find the lowest
effective value for the DFSENS parameter.
Appendix
119
10.10 Conversion Factors for Secondary Units
The 920i has the capability to mathematically convert a weight into many different types of units and instantly
display those results with a press of the UNITS key.
Secondary and tertiary units can be specified on the FORMAT menu using the SECNDR and TERTIA
parameters, or by using serial commands.
• To configure secondary or tertiary units using the front panel menus, use the Table 10-12 to find the
conversion multiplier for the MULT parameter. For example, if the primary unit is pounds and the
secondary unit is short tons, set the MULT parameter to 0.000500.
• To configure secondary or tertiary units using serial commands, use the Table 10-12 to find the
conversion multiplier for the SC.SEC.MULT or SC.TER.MULT command. For example, if the primary
unit is pounds and the secondary unit is short tons, send the serial command SC.SEC.MULT=
0.0005<CR> to set the multiplier for the secondary units.
NOTE: Ensure that the secondary decimal point position is set appropriately for the scale capacity in the
secondary units. If the converted value requires more digits than are available, the indicator displays an overflow
message (OVERFL).
For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is
set to 8888.888, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a
conversion factor of 2000, the secondary units display needs five digits to the left of the decimal point to display
the 10000 lb secondary units value.

10.11 Audit Trail Support
Audit trail support provides tracking information for
configuration and calibration events. A separate
calibration counter is provided for each scale; a single
configuration counter tracks all configuration
changes.
To prevent potential misuse, unsaved configuration or
calibration changes are counted as change events;
restoration of the previous saved configuration or
calibration is also counted.
For NTEP and Measure Canada modes, there are
twonumbers displayed; Configs and Calibs. The
Configsnumber tracks changes to the legally
relevantconfiguration parameter changes. The Calibs
numbertracks changes to the scale calibration.
In OIML mode, there is only one number
displayed;Audit Trail. The Audit trail number is
incremented forany legally relevant configuration
parameter changesand all calibration changes. The last
date the scale wascalibrated is also displayed.
10.11.1 Displaying Audit Trail Information
To display audit trail information, press and hold the
Gross/Net key for several seconds. Various audit trail
information screens can then be accessed by pressing
the front panel number keys ( 1–5 and 0). The exact
format of each screen depends on the regulatory
agency specified for the REGULAT (FEATURE
menu) parameter.
The initial screen shown when entering the audit trail
display (or whenever the 1 key is pressed while
showing audit trail information) shows the legally
relevant (LR) version number (software version for
the code that provides audit trail information), a
calibration count and, if REGULAT=NTEP, a
configuration count.
Press 2 to show the configuration count display. This
display shows the number of times the system has
been configured, the date and time of the last
configuration event, and the before/after information
for the most recent change of date and time.
Press the Down key to show the number of
weighments, number of configuration events, number
of calibrations, and the date and time of the most
recent calibration for the first configured scale.
Continue pressing the Down key to cycle through the
information for all configured scales.
Press 3 to show the number and the most recent date
and time of power-on events, power-on configuration
changes, and user program loads.
Use the Down key to show the number of power-on
calibration events for all configured scales.
Press 4 to show the number of times the OEM version
number has been changed, and the date and time of
the most recent change.
Press 5 to show the number of times the configuration
has been reset, the date and time of the most recent
reset, and the indicator EIN number.
Press 0 to show the indicator and LR software
versions.
When done, press the Gross/Net key to exit the audit
trail displays.
10.11.2 Printing Audit Trail Information
Audit trail information can be printed by pressing the
PRINT key while displaying the audit trail or by
sending the DUMPAUDIT serial command. Audit
trail information is sent to the port specified on the
AUD.PORT serial command or by the AUDFMT
parameter (PFORMT menu).
NOTE: Printed audit trail information contains data for all
scales, whether configured or not, that can be supported by
the indicator. Displayed audit trail information shows data only
for currently configured scales.
