6 920i Installation Manual
2.0 Installation
This section describes procedures for connecting load
cell, digital I/O, and serial communications cables to
920i indicator. Assembly drawings and
the
replacement parts lists for the universal model are
included for the service technician. See
Section 10.12
on page 117 for dimension drawings of the all models.
• 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.
2.1 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 14 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.
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 Cable Connections
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 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
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
Foil (silver side out)
Shield wire (cut)

• 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.
2.3.2 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 7.
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 Tab le 2-1.
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.

2.3.4 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.

2.9 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 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.
Replacement Procedure
For best results, replace the battery while in weigh
mode and with AC power applied. Use care not to
bend the battery retaining spring.
If the battery must be replaced with power removed,
do the following immediately after restoring power:
1. Place indicator in setup mode.
2. Go to the Version Menu and press the Reset
Config
softkey. If connected using iRev,
configuration can be reset by using monitor
mode to enter the RESETCONFIGURATION
command followed by the RS command.
See Figure 2-5 on page 10 for CPU board battery
location and orientation (positive side up).
Risk of explosion if battery is replaced
with incorrect type. Dispose of batteries
per manufacturer instruction.

3.0 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.
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.
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
utility.
NOTE: Some configuration parameters, such as those
used to configure the
be accessed through the configuration menus.
provides the most complete and efficient
configuration interface for the
3.1.1 iRev Configuration
The iRev configuration utility provides the preferred
method for configuring the
on a personal computer to set configuration
parameters for the indicator. When
is complete, configuration data is downloaded to the
indicator.
iRev 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.

When configuration is complete, press the Exit or Save
and Exit
softkey to exit setup mode, then replace the
setup switch access screw.
•The Exit softkey exits setup mode without saving
parameter changes to NV RAM. Changes made
to the configuration remain in the system until
indicator power is cycled.
• Save and Exit writes all parameter changes to NV
RAM before returning to normal mode.
Figure 3-1. iRev Hardware Configuration Display
To use iRev, do the following:
1. Install iRev on an IBM-compatible personal
computer. See
Section 5.0 on page 54 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 program.
iRev 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: The
interface is different, but the parameters set are the
same.
See Section 5.0 on page 54 for more information about
using iRev to configure the 920i.
Configuration 19
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, serial
command configuration sends commands to the
indicator serial port; unlike
iRev, 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 84 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
press the center softkey,
left navigation key to select the A/D, then
Add. The A/D is then moved
to the Associated A/D’s column. If no other A/D’s are
listed in the
softkey changes to
AVAILABLE A/D’s column, the center
Done, as shown in Figure 3-2.
Press Done to exit the Scale Configuration display.
See Section 10.4 on page 106 for information about
configuring serial scales.
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.
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.
3.1.5 Total Scale Configuration
The output of two or more A/D scales or iQUBE
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 iQUBE systems to configure
as a total scale. (Use the
available A/D scales or
Change Type softkey to show
iQUBE systems; use the right
navigation key to select the total scale sources.) In
iRev, assign the total scale to an unused position then
select source scales from the existing A/D scales or
iQUBE systems.
Figure 3-2. Scale Configuration Display
20 920i Installation Manual
The FORMAT configuration of the total scale (see
Figure 3-5 on page 26) 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 overrange 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.
3.2 Menu Structures and Parameter Descriptions

Sets the level, in display divisions, at which scale motion is detected. If motion is not
detected for 1 second or more, the standstill symbol lights. Some operations, including
print, tare, and zero, require the scale to be at standstill. Maximum legal value varies
depending on local regulations.
If this parameter is set to 0 the standstill annunciator does not light; operations normally
requiring standstill (zero, tare, print) are performed regardless of scale motion. If 0 is
selected, ZTRKBND must also be set to 0.
Specifies the length of time the scale must be out of motion, in 0.1-second intervals, before
the scale is considered to be at standstill. Values greater than 10 are not recommended.
Determines the point at which the display blanks and an out-of-range error message is
displayed. Maximum legal value varies depending on local regulations.
Specifies the minimum number of grads required for a weighment to be added to the
recorded number of weighments.

DELAY
Selects the digital filtering rate used to reduce the effects of mechanical vibration from the
immediate area of the scale.
Choices indicate the number of A/D conversions per update that are averaged to obtain the
displayed reading. A higher number gives a more accurate display by minimizing the effect
of a few noisy readings, but slows down the settling rate of the indicator.
NOTE: When configuring non-A/D scales, set the DIGFLTx parameters to 1 to disable
filtering.
See Section 10.9 on page 114 for more information about digital filtering.
Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall
outside the filter threshold (DFTHRH parameter) before digital filtering is suspended.
See Section 10.9 on page 114 for more information about digital filtering.
Digital filter cutout threshold. Specifies the filter threshold, in display divisions. When a
specified number of consecutive scale readings (DFSENS parameter) fall outside of this
threshold, digital filtering is suspended. If NONE is selected, the filter is always enabled.
See Section 10.9 on page 114 for more information about digital filtering.
Enables RATTLETRAP® digital filtering. RATTLETRAP is most effective at filtering repeating
vibrations caused by mechanical noise from nearby machines but may increase settling
times over standard digital filter selections.
Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital
converter. Lower sample rate values provide greater signal noise immunity: the default 120
Hz value may be too fast to provide the desired stability in some static weighing
applications.
NOTE: The maximum total sample rate for all configured A/D channels—the sum of the
sample rates for all scales—is 1200 Hz. For example, up to ten scales can be configured
with 120 Hz sample rates, or up to twenty scales with 60 Hz sample rates.
Power up mode. In GO mode, the indicator goes into operation immediately after a brief
power up display test.

In DELAY mode, the indicator performs a power up display test, then enters a 30-second
warm up period. If no motion is detected during the warm up period, the indicator becomes
operational when the warm up period ends; if motion is detected, the delay timer is reset
and the warm up period repeated.
Enables or disables push-button and keyed tares. Possible values are:
BOTH: Both push-button and keyed tares are enabled
NOTARE: No tare allowed (gross mode only)
PBTARE: Push-button tares enabled
KEYED: Keyed tare enabled
Accumulator. Specifies whether the scale accumulator is enabled. If enabled, accumulation
occurs whenever a print operation is performed.
Scale visibility. Specifies whether scale data is displayed.
