Introduction 1
1.0 Introduction
This manual is intended for use by individuals responsible for installing the CLS-920i Cargo Lift Scale along with
the 920i HMI digital weight indicator. This manual covers information on the installation of the scale carriage,
signal cable installation (if applicable), and the installation, configuration, and calibration of the 920i HMI digital
weight indicator.
Note
While the functionality remains the same for the standard 920i HMI digital weight indicator, there are certain
menu choices found in the User Configuration section of this manual that are specific to this application.
The CLS-920i Operator Card, PN 96313 included with this manual, provides basic operating instructions for users
of the CLS-920i and the 920i HMI digital weight indicator. Please leave the operator card with the indicator when
installation and configuration is complete.

2CLS-920i Installation Manual
1.1 O ver vie w
The CLS-920i Cargo Lift Scale is a rugged, dependable cargo lift scale that can withstand many years of repeated
use. When mounted on a forklift, the CLS-920i saves time and money. It immediately weighs the load when it is
picked up with a forklift instead of carrying the load to a floor scale.
The CLS-920i is used with Rice Lake’s 920i HMI digital weight indicator and the setup and calibration of the
indicator is discussed in detail in this manual.
Onboard Features
Features of the basic cargo lift scale include:
Features of the scale carriage include:
• NTEP approved, Class III, 5,000 lb, 1:1000
• Class II forklift with 16" cleat style carriage
• Two (2) stainless steel load cells
• Cover plate
• Mechanical overload protection
• Flexure plates with bolts welded into place
• Welded centering pin
•Viewport
• Two-channel iQube
• Wired or wireless communication

CLS-920i Installation Manual 3
1.2 Considerations Before Installation
While the CLS-920i Cargo Lift Scale will fit most typical forklifts, there are certain considerations that must be
taken into account prior to installing the scale. Due to the extra weight of the CLS-920i, the net lifting capacity of
the forklift is decreased by approximately 10%. Use the following formula below, to calculate the net capacity of
the unit.
NOTE: Formulas can give you a good estimate of how capacity will be affected. But you should work closely with your
forklift manufacturer before making a decision. Their data reflects, in most cases, testing with specific forklifts and
attachments.
Net Capacity = A(B + C) - D (E + F)
E + G + H
Where:
A = Truck basic capacity in pounds
B = Inches from the front wheel center line to fork face
C = Inches from fork face to truck rating point (usually 24")
D = Weight of the scale in pounds (428 lbs)
E = Inches from the front wheel center line to the carriage face
F = Inches from the carriage face to scale Horizontal Center of Gravity (HCG)
G = J + K (inches from the carriage face to rear face of load
H = Inches from fork face to new truck rating point
J = Thickness of fork
K = Thickness of scale
CAUTION
Another consideration is the indicator power source will be connected directly to the battery of the
forklift. Most typical is 12 volts for propane, gas and diesel forklifts. However, some diesel forklifts are 24
volts.
The CLS Series Cargo Lift scale will not operate on a positive ground forklift. Verify the forklift has a
negative ground electrical system. Refer to the forklift users manual to further verify grounding
requirements.
1.2.1 CLS Classes and ID Plates
During the initial sale or installation of the CLS-920i, you need to remind your customer that they must have an ID
plate on their forklift updated stating the new lifting capacity and center of gravity information. This requirement is
per OSHA rules and regulations.

4CLS-920i Installation Manual
1.3 920i Digital HMI Indicator
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.
• Four 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.
1.3.1 Front Panel
The 920i front panel, shown in Figure 1-2, consists of a 27-button keypad with a large backlit LCD display. The
keys are grouped as five configurable softkeys, five primary scale function keys, four navigation keys, and numeric
entry keys.
Weight information is displayed with a graphical scale in six font sizes up to 1.2 inches. Up to four scale widgets
can be displayed in legal-for-trade, multiple-scale applications. Status areas on the display are used for operator
prompts and entering data. The remainder of the display can be graphically configured for representation of a
specific application. Display contrast can be adjusted with the LCD contrast potentiometer.

The 920i is housed in a stainless steel enclosure that is rated for NEMA 4X/IP66.

CLS-920i Installation Manual 5
1.3.3 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.
1.3.4 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 ( ) annunciator lights to indicate the scale is zeroed.
Acquire Tare
1. Place container on scale and wait for the standstill annunciator ( ).
2. Press the TARE key to acquire the tare weight of the container.
3. Display shifts to net weight and shows the word Net on the display.
Remove Stored Tare Value
1. Remove all weight from the scale and wait for the standstill annunciator ( ).
2. Press the TARE key (or, in OIML mode, the ZERO key). Display shifts to gross weight and shows the word

Accumulator Functions
The accumulator must be enabled before use in either normal mode or setpoint operations. Once enabled, weight
(net weight if a tare is in the system) is accumulated whenever a print operation is performed using the PRINT key,
digital input, or serial command. The scale must return to zero (net zero if a tare is in the system) before the next
accumulation.
The Display Accum softkey can be configured to display the current accumulator value. Printing while the
accumulator is displayed, or when the setpoint PSHACCUM function is active, uses the ACCFMT print format
Press the CLEAR key twice to clear the accumulator.
