Introduction 1
About This Manual
This manual is intended for use by qualified service
technicians responsible for installing and servicing the
CW-90/CW-90X checkweighing scale.
Warning
Do not open the indicator enclosure!
Refer all repairs and modifications to your
distributor or qualified service technician.
Ensure power is disconnected prior to
installing, servicing, transporting, or
storing equipment.
Authorized distributors and their employees
can view or download this manual from the
Rice Lake Weighing Systems distributor

1.0 Introduction
The CW-90/CW-90X is a high-speed digital weight
indicator and scale base programmed to compare
weight readings with predetermined tolerance limits
defining an “accept” band.
If the current weight reading is within the acceptable
range, the green “ACCEPT” LED is illuminated. If
the current weight reading is less than the acceptable
range, one or more of the red “UNDER” segments is
illuminated. If the current weight reading is greater
than the acceptable range, one or more of the yellow
“OVER” segments is illuminated.
Features include:
• Large .8” (20.3 mm) LED display with
“under,” “accept,” and “over” bands
• Full numeric keypad (CW-90 only)
• Four configurable digital inputs/outputs
• Two independent communication ports (2)
full duplex, (1) unidirectional active 20 mA
current loop
1.1 Operating Modes
The CW-90/CW-90X has two modes of operation:
Normal (Weighing) Mode
Normal mode is the “production” mode of the
indicator. The indicator displays the gross or net
weight, depending on whether a tare has been entered.
LED annunciators indicate the type of weight value.
Menu mode
Most of the procedures described in this manual,
including configuration and calibration, require the
indicator to be in Menu mode.To enter Menu mode,
press the MENU key (if the Audit jumper is in the
“ON” position).The indicator displays “AUDIT.”
If the Audit jumper is in the “OFF” position, remove
the large fillister head screw from the bottom of the
enclosure. Insert a screwdriver into the access hole
and press the setup switch once to enter Menu mode.
1.2 Keypad Functions
Key Function
Turns the CW-90/CW-90X unit on/off.
NOTE: If the PC jumper is set to SW, the
POWER button must be used to turn the unit
on and off. If the PC jumper is set to ON, the
unit will automatically power on when it’s
plugged in and the only way to turn it off is to
unplug power.
Enters Menu mode, allowing configuration if the
Audit jumper is in the “ON” position. Also used
as an “escape” key in Menu mode.
Sets the current gross weight to zero, provided
the amount of weight to be removed or added
is within the specified zero range and the scale
is not in motion. The zero band is defaulted to
1.9% of full scale, but can be configured for up
to 100% of full scale.
NOTE: 1.9% is required for legal for trade
applications.
Switches the weight display to an alternate unit.
The alternate unit is defined in the Setup menu,
and could be kg, g, lb, oz, or lb/oz.
Conversions of the weight reading, the Tare
value, the Over value, and the Under value
occur when the unit of measure is changed
with the Units key.
Sends “on-demand” serial information out the
serial port, provided the conditions for standstill
are met.
Performs one of several predetermined Tare
functions dependent on the mode of operation
selected in the TAREFN parameter (See
Section 3.4.1 on page 16).
OVER
Allows the display of the current “over
tolerance” value, or allows setting the “over
tolerance” value.

LED Description
Zero (Center of Zero) LED
While in gross weight display mode, this LED
indicates that the current displayed weight
reading is within +/-0.25 display divisions of the
acquired zero, or is within the center of zero
band.
When in the net weight display mode, it
indicates that the current net weight reading is
within +/-0.25 display divisions of the center of
net zero. A display division is the resolution of
the displayed weight value, or the smallest
incremental increase or decrease that can be
displayed or printed.
G/B LED
Gross weight mode (or Brutto in OIML mode)
N LED
Net weight display mode.
T LED
Indicates that a tare has been acquired and
stored by the system.
PT LED
Indicates that a preset tare weight has been
keyed in or entered via the EDP serial port.

Introduction 3
1.4 Bar Graph LEDs
The bar graph LEDs provide you with a fast way of determining if a container is too heavy (OVER), too light
(UNDER), or is within an acceptable weight range (ACCEPT).
ACCEPT
UNDER OVER
Greatly over
Moderately under
Slightly under
Acceptable weight
Moderately over
Slightly over
Greatly under
Figure 1-2. Bar graph LEDs
You can enable the UNDER and OVER lights to act as a graph as illustrated in Figure 1-2, or to appear as one a
solid bar regardless to how far over/under a weighment is. This is done by accessing the Feature menu (see
Section 3.4.2 on page 20).
Red Segments
When illuminated, this indicates an underweight condition; the container weighs less than the lowest acceptable
value. The leftmost red segments indicate that the container weight is far below the acceptable weight band
(greatly under); the rightmost segments indicate that the container weight is almost in the acceptable weight
band, but still under (slightly under). Illuminating the center segments indicates middle-ground, or moderately
under.
Green Segment
Indicates an acceptable value. When lit, the green segment (one solid bar) indicates that the container weight is
within the actual acceptable band of weight limits.
Yellow Segments
When illuminated, this indicates an overweight condition; the container weighs more than the highest acceptable
value. The rightmost yellow segments indicate that the container weight is far above the acceptable weight band
(greatly over); the leftmost segments indicate that the container weight is almost in the acceptable weight band,
but still over (slightly over). Illuminating the center segments indicates middle-ground, or moderately over.

4CW-90/90X Installation Manual
2.0 Installation
This section contains instructions on unpacking and assembly, leveling, making power connections, load cell
wiring, wiring standard serial port, optional network communications, wiring optional digital outputs, optional
backup battery operation, board diagrams, and power-up sequence.
Do not pick up the scale by the “spider” assembly which supports the platter. Lifting by the
spider may damage the load cell. Lift the scale from under the base to move it. If the rear panel
of the indicator is removed, align the gasket holes carefully to prevent driving a screw through
the gasket and causing a leak. Tighten screws to 15 in/lbs (1.7 N-m) in alternating patterns shown Figure 2-1.

2.1 Unpacking and Assembly
The indicator head and support column or stand are shipped detached from the scale platform.
1. Remove all assemblies from the shipping carton. Notice that the head and scale platform are joined by a
load cell cable. This cable is correctly wired to the load cell terminal in the indicator head. Do not pull
with excessive force on the connections at either end of this cable.
2. If mounting the head onto a column, remove the platter from the scale platform and set aside.
3. Invert the platform to access the column mounting holes on the rear and bottom of the platform.
4. Position the column over the four mounting holes. Install (2) 1/4-20 x 3/4” cap screws and (2) lock
washers in mounting holes on bottom side of the platform. Install (2) 1/4-20 x 1-3/4”cap screws, (2) lock
washers, and (2) column supports in mounting holes on rear of platform. Install coupling nuts, counter
bored end first, onto threaded stem of rubber feet. Install feet onto bottom side of the column.
5. Turn the CW-90/90X upright and replace the platter on the platform.
6. Attach indicator to the column with the two knobs and nylon washers provided. Position nylon washers
between indicator enclosure and column mounting holes.

Installation 5
2.2 Leveling
Select a location for the CW-90/90X that is reasonably
level and free of vibrations and air currents. Adjust the
four corner feet on the base and refer to the bubble
level on the inside frame. The base should not rock
and the feet should have solid contact with the
surface. If using a column, adjust the two column feet
until they make solid contact with the support surface.
NOTE: Ensure the nut on each foot’s bolt is secured flush
against the scale base.
2.3 Making Power Connections
The power source used for the CW-90 must be
properly grounded to an acceptable earth ground. If
the indicator is remotely mounted, the platform must
be separately grounded from the chassis ground screw
located on the bottom of the platform. Connect this
screw with 18 gauge wire to the same earth ground
system as the AC power source. Failure to ground the
base may cause static buildup and incorrect weights.
NOTE: The CW-90 must be installed near an easily accessible
power outlet to allow for quick disconnect in case of
emergency.
2.4 Enclosure Disassembly
The indicator enclosure must be opened to connect
cables for load cells, communications, and digital
inputs/outputs.
Warning
Before opening the unit, ensure the
power cord is disconnected from the
power outlet. The power outlet must be located near the
indicator to allow the operator to easily disconnect power
to the unit.
Ensure power to the indicator is disconnected, then
place the indicator face-down on an antistatic mat.
Remove the screws holding the backplate to the
enclosure body, then lift the backplate away from the
enclosure and set it aside.
2.5 Load Cell Wiring
On all complete units (indicator head and base), the
load cell has been wired to the indicator’s CPU load
cell terminal at the factory. If you have purchased just
the indicator head, you must wire the load cell.
Wire the cable to the CPU board’s J1 connector as
shown in Table 2-1. Leave any excess cable outside of
the indicator head during installation

NOTE: If using a 4-wire connection, set JP1 and JP2 to ON. If
using a 6-wire connection, set JP1 and JP2 to OFF.
2.6 Wire Specifics
Wires connecting to J1, J2, J3, or J4 should adhere to
the following specifications:
Table 2-2. Wire specifications for connectors
Wire Range Wire Strip Length
28~12 AWG stranded or solid wire 5~6 mm (3/16” ~ 1/4”)
2.7 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 2-3).
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 2-3 on page 6).
• Finish installation using cable mounts and ties
to secure cables inside of indicator enclosure.

2.7.1 Serial Communications
Wire the serial communications cables to J2, which is
Port 1 (5-wire RS-232 port). J3 is Port 2 (RS-232 and
20 mA). Connect communications cables to J2 and J3
as shown in Table 2-3.
Use cable ties to secure serial cables to the inside of
the enclosure.
Port 1 supports full duplex RS-232 communications
only; Port 2 provides either active 20 mA output or
duplex RS-232 transmission. Both ports are
configured using the SERIAL menu. See
Section 3.4.4 on page 26.

2.7.2 Digital I/O
The Digital I/O can be configured as either digital
inputs or digital outputs as determined by the DIO
menu (see Section 3.4.4 on page 26). The inputs are
active (on) with low voltage (0 VDC) and can be
driven by TTL or 5V logic without additional
hardware. Use the DIG I/O menu (see Section 3.4.4
on page 26) to configure the digital inputs. LEDs on
the CPU board light when digital inputs are active (see
Figure 2-4).
Digital outputs are typically used to control relays that
drive other equipment. Outputs are designed to sink
not source, switching current. Each output is a
normally open connector 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 5 VDC supply. LEDs on the
CPU board light up when the digital outputs are active
(see Figure 2-4).

2.8 Enclosure Reassembly
Once the cabling is complete, position the backplate
over the enclosure and reinstall the screws. Use the
torque pattern shown in Figure 2-1 on page 4 to
prevent distortion. Torque to 15 in/lbs (1.7 N-m).
2.9 Board Removal
If you must remove the CW-90/90X CPU board, use the
following procedure:
1. Disconnect power to the indicator. Remove
backplate as described in Section 2.4 on
page 5.
2. Disconnect power supply cable from
connector J9 on the CW-90/90X CPU board.
3. Disconnect the wires at the following
connectors: J1, J2, J3, J4.
4. There are two boards: the CPU board and the
keypad display board. Remove the five
screws connecting the CPU board (see
Figure 2-4), then lift the board out of the
enclosure.
To replace the CPU board, reverse the above
procedure. Be sure to reinstall cable ties to secure all
cables inside the indicator enclosure.
2.10 Battery Replacement
Risk of explosion if battery is replaced with
incorrect type.
Dispose of batteries per manufacturer
instructions.
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 this battery includes time
and date, IDs, and configuration information. If any
data is lost, the indicator configuration can be restored
from the PC. Watch for the low battery warning on the
LCD display and periodically check the battery
voltage on the CPU board. 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 10 years. Use
Revolution III to store a copy of the configuration
before attempting to replace the battery.
For best results, replace the battery while in weigh
mode and with AC power applied. use care not to
bend the battery retaining spring.
2.11 Installing Option Cards
Option cards are not hot-pluggable.
Disconnect power cord entirely
before installing option cards.
NOTE: Ethernet port is not suitable for connection to circuits
used outside the building and is subject to lightning or power
faults.
Each option card is shipped with installation
instructions specific to that card. For specific
instructions on the WLAN card, refer to Section 8.0
on page 54.
The general procedure for all option cards is:
1. Disconnect power cord from the indicator.
2. Remove the backplate as described in
Section 2.4.
3. Install the plastic standoffs in the standoff
holes (shown as black-shaded circles in
Figure 2-5).
4. Carefully align the option card connector with
the J5 connector on the CPU board.
5. Press down firmly to seat the option card in
the CPU board connector.
6. Make connections to the option card as
required. Use cable ties to secure loose cables
inside the enclosure. When installation is
complete, reassemble the enclosure as
described in Section 2.8.
