1.0Introduction
The 820i is a programmable, multi-channel digital
weight indicator/controller. The configuration can be
performed using the front panel, with an attached
1
®
PS/2
-type keyboard, or using the Revolution utility.
Custom event-driven programs can be written with the
iRite-IDE
®
language. These programs are compiled
with an iRite-IDE compiler utility, which can only be
downloaded into the indicator. The RLWS Web
Update utility can be used to download 820i firmware
upgrades to a PC from the RLWS web site; Revolution
provides functions for installing the new software into
the 820i.
Onboard Features
Features of the basic 820i include:
•Support for two A/D or serial scale inputs, or
total of all scales.
•Eight digital I/O channels on main board,
each configurable as either input or output.
•Two serial ports on main board support
duplex RS-232 up to 115200 bps. Port 2
supports RS-232 with hardware handshaking;
Port 4 supports RS-232, 20mA output, and
2-wire RS-485 communications.
•Available in 115 VAC and 230 VAC North
American and European versions.
•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 using twenty auxiliary print formats.
•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-IDE
language.
The 820i is NTEP-certified for Classes III and III L at
10,000 divisions. See Section 10.13 on page 103 for
more information about additional certifications and

The 820i is available in universal (tilt-stand) and panel
mount enclosures. 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 model
(Section 1.4 on page 4).
1.1Operating Modes
The 820i 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 820i 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
from the enclosure. Insert a screwdriver or a
screw
similar tool into the access hole and press the setup
switch once. The indicator display changes to show
scale configuration menus.
1.2Indicator Operations
Basic 820i 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
OIML mode); net mode is indicated by the word Net.

2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the 820i
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 2.9 on page 11 for parts kit contents.
2.3.1Cable 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 (13 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).
2.2Enclosure Disassembly
The indicator enclosure must be opened to install
option cards and to connect cables for installed option
cards.
The 820i has no on/off switch. Before
opening the unit, ensure the power cord is

2.3.4Digital 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
other equipment. Outputs are designed to sink,
drive
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.

identical hardware configuration.
To use
Revolution, do the following:
1. Install
Revolution on an IBM-compatible

using
3.1.2Serial Command Configuration
The serial command set can be used to configure the
820i indicator using either a personal computer,
terminal, or remote keyboard. Like
Revolution, serial
command configuration sends commands to the
indicator serial port; unlike
Revolution, ser ial
commands can be sent using any external device
capable of sending ASCII characters over a serial
connection.
Configuration15
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
sett i ngs. See Section 9.0 on page 79 f or more
information about using the serial command set.
3.1.3Front Panel Configuration

They can be set using
Revolution or through the front

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.
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.
3.1.4Multi-Range and Multi-Interval Scales
The 820i 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
SPLIT parameter to select 2RNG or 3RNG (for
the
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.
16820i Installation Manual
3.1.5Total Scale Configuration
The output of A/D scales, serial 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
as a total scale. (Use the
available A/D scales or
iQUBE systems to configure
Change Type softkey to show
iQUBE systems; use the right
navigation key to select the total scale sources.) In
Revolution, assign the total scale to an unused
position then select source scales from the existing
A/D scales or
iQUBE systems.
The FORMAT configuration of the total scale (see
Note
Figure 3-5 on page 23) 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.
Total scale function is not supported for
multi-range or multi-interval scales at this
time.

Decimal point location. Determines the location of the decimal point or dummy zeros in the
secondary or tertiary units display.
Display divisions. Selects the value of minimum division size of the displayed weight for
secondary or tertiary units display.
Specifies secondary or tertiary units for displayed and printed weight. Values are: lb=pound;
kg=kilogram; g=gram; oz=ounce; tn=short ton; t=metric ton; gn=grain; troyoz=troy ounce;
troylb=troy pound; lt=long ton.
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 10.8 on page 98 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:
