About This Manual
This manual is intended for use by service technicians
responsible for installing and servicing 320IS Plus
digital weight indicators. This manual applies to
indicators using Version 2.0 of the 320IS Plus
software.
Configuration and calibration of the indicator can be
accomplished using the indicator front panel keys, the
EDP command set, or the 320IS Plus configuration
utility. See Section 3.1 on page 13 for information
about configuration methods.
Some procedures described in this
manual require work inside the
indicator enclosure. These procedures
are to be performed by qualified
service personnel only.
Improper specification, installation, or service of this
equipment could result in personal injury or property
damage.
The 320IS Plus is a Factory Mutual-Entity approved
component. This approval is valid only if the installation
conforms to the guidelines described in this manual and
FM-approved control drawing (PN 72717). If
modifications are made to the installation procedure, or
the instrumentation is changed in any way, Factory
Mutual approval is void and the customer becomes fully
responsible for such modifications.

1.0 Introduction
The 320IS Plus is a single-channel digital weight
indicator designed and approved to operate as an
intrinsically safe system in a wide variety of scale and
weighing applications. The indicator is housed in a
NEMA 4X/IP66-rated stainless steel sealed case. The
standard unit is equipped with a tilt stand base for
tabletop or wall mounting applications. The indicator
front panel consists of a large (0.8 in, 20 mm,
16-segment), six-digit LED display, 24-button keypad
and eight LED annunciators. Features include:
• Drives up to four 350Ω or eight 700Ωload
cells
• Supports four- and six-wire load cell
connections (six-wire remote sense
recommended)
• Full-duplex fiber optic interface to attach an
external I/O board located in the safe area
The 320IS Plus is NTEP-certified and pending
Measurement Canada approval for Classes I, II and III
at 10,000 divisions. See See Section 9.10 on page 68
for detailed specifications.
Available with optional I/O Module (PN 72721):
• Four configurable digital inputs
• Four digitally-controlled single pole single
throw-normally open non-latching relay
contact outputs
• Electronic data processing (EDP) port
communications at up to 38400 bps for full
duplex RS-232/RS-422/RS-485 and Current
loop
• Printer port communications at up to 38400
bps for full duplex RS-232/RS-422/RS-485
and Current loop
• Two 16–bit analog output channels provide
±10V or ±5V, 0-5V or 0-10V, and 4-20 mA
tracking of gross or net weight values

approved for:
• Classes I, II, and III
• Divisions 1 and 2
• Groups A, B, C, D, E, F and G
• T-rating T4
Only devices that have FM Entity Approval with
proper entity parameters may be used unless
specifically listed in this manual or control drawing
PN 72717 as part of the Rice Lake Factory Mutual
systems approval. Failure to comply with this voids
the FM approval.
The classification of hazardous materials are different
in the US and European standards. Because of this, the
safety class of the 320IS Plus is declared in the
following regulations:
• US standards: Class I, II, III, DIV1, Groups
A-G
Substitution of components may impair
intrinsic safety.
To prevent ignition of flammable or
combustible atmospheres, disconnect

1.2 Operating Modes
The 320IS Plus has three modes of operation.
Normal (Primary) Mode
Normal mode is the “default” mode of the indicator.
The indicator displays gross or net weights as
indicated by LED annunciators (see Figure 1-1) to
indicate scale status and the type of weight value
displayed.
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 backplate. Insert a
non-metal screwdriver or a similar tool into the access
hole and press the setup switch once. The indicator
display changes to show the word CONFIG.
Test Mode
Test mode provides a number of diagnostic functions
for the 320IS Plus indicator. Like setup mode, test
mode is entered using the setup switch (Section 8.8 on
page 59) .
1.3 Front Panel Keypad
Figure 1-1 shows the 320IS Plus LED annunciators, keypad, and normal mode key functions. Table 1-1 on page 3
details the function of each key in different display modes.
The symbols shown above the keys (representing up, down, enter, left, right) describe the key functions assigned
in setup mode. In setup mode, the keys are used to navigate through menus, select digits within numeric values,
and increment/decrement values. See Section 3.1.3 on page 14 for information about using the front panel keys
in setup mode.

1.4 LED Annunciators
The 320IS Plus display uses a set of eight LED annunciators to provide additional information about the value
being displayed (see Figure 1-1 on page 2):
•TheGross and Net annunciators are lit to show whether the dispalyed weight is a gross or net weight.
• Center of zero ( ): Gross weight is ±0.25 graduations of zero. This annunciator lights when the scale is
zeroed.
• Standstill ( ): Scale is at standstill or within the specified motion band. Some operations, including
tare functions and printing, can only be done when the standstill symbol is shown.
• The Tare Aquired ( )lights to show that a tare value has been entered.
•TheCount annunciator is lit to show that the indicator is in piece count mode.
•lb and kg annunciators indicate the units associated with the displayed value: lb=pounds, kg=kilograms.
Two units of measurement can be chosen to toggle between.
The displayed units can also be set to ounces (oz), short tons (tn), metric tons (t), grams (g), or they can be
disabled. A user-defined unit can also be set as secondary unit by declaring a conversion factor in the setup
menu. The lb and kg LED’s function as primary and secondary units annunciators for some combinations of
primary and secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the lb annunciator is
lit for primary units, kg for secondary units.
Table 1-2 shows which annunciators are used for all combinations of configured primary and secondary units.
For example:
• If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb LED is lit for primary
units, kg for secondary units.
• If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb LED is lit for primary units,
kg for secondary units. There is no LED for short tons, so the kg LED is used as the secondary units
annunciator.
• If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary units
(tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs are
used as primary and secondary units annunciators.
