About This Manual ................................................................................................................................... 1
This manual is intended for use by service technicians
responsible for installing and servicing 390HE digital
weight indicators.
Configuration and calibration of the indicator can be
accomplished using the indicator front panel keys, the
™
EDP command set, or the Revolution
utility. See
Section 3.1 on page 8 for information
configuration
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.
1.0Introduction
The 390HE is a single-channel digital weight
indicator housed in a NEMA 4X fiberglass reinforced
polyester (FRP) enclosure. The indicator front panel
consists of a 1-inch (25 mm), six-digit, liquid crystal
(LCD) display and a five-button keypad. Features
include:
•Drives up to four 350Ω or eight 700Ω load
cells
•Supports 4- and 6-wire load cell connections
•Electronic data processing (EDP) port for full
duplex, RS-232 communications at up to
19200 bps
•Piece count mode for basic parts counting
functions.
The 390HE is NTEP-certified for Classes III and III L
at 10,000 divisions. See for detailed specifications.
1.1Operating Modes
The 390HE has several modes of operation:
Normal (weighing) mode
Normal mode is the “production” mode of the
indicator. The indicator displays gross or net
weights as required, using the LCD annunciators
described in
scale status and the type of weight value
displayed. Once configuration is complete and a
legal seal is affixed to the back of the indicator,
the 390HE can operate only in normal mode.

The Operator Card included with this manual
provides basic operating instructions for users of the
390HE. Please leave the Operator Card with the
indicator when installation and configuration are
complete.
Piece count mode
In piece count mode, the indicator display shows
the number of parts on the scale rather than the
weight of those parts. Piece count mode has two
submodes:
•Count display mode displays the current parts
count and allows ticket printing using the
CFMT print format.
•Sample acquisition mode is used to calibrate
the indicator for parts counting.
Operator access to piece count mode is disabled
when the indicator is shipped from the factory. See
Section 6.0 on page 26 for detailed information
about counting operations.
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, open the enclosure and press
the setup switch mounted on the end of the
pushbutton switch board. The indicator display
changes to show the word
Test mode
CONFIG.
Test mode provides a number of diagnostic
functions for the 390HE indicator. Like setup
mode, test mode is entered using the setup switch.

The 390HE display uses a set of LCD annunciators to
provide additional information about the value being
displayed.
Figure 1-2 on page 3 shows these
annunciators and their meanings.
G The displayed weight is a gross weight.
N The displayed weight is a net weight.
Scale is at standstill or within the specified motion
band. Some operations, including zero, tare, and
printing functions, can only be done when the

lb, kg, PC
Three arrow annunciators on the right side of the LCD
display indicate the units associated with the
displayed value. The bottom arrow annunciator (PC)
is lit when the indicator is in piece count mode. The
top and middle arrows, labeled lb and kg, show
primary and secondary units, as described below:
•If the displayed weight is in pounds, the top arrow
(lb) is lit; if kilograms, the middle arrow (kg) is
lit.
•If the primary unit of weight is pounds, the middle
(kg) arrow is lit for secondary units—or, if the
primary unit is kilograms, the top (lb) arrow is lit
for secondary units, unless the secondary unit of
weight is the same as the primary unit.
•If neither primary nor secondary units are pounds
or kilograms, the top arrow is used as a primary
units annunciator and the middle arrow is used as
the secondary units annunciator. A set of
replacement overlay decals is included in the parts
kit for units other than pounds and kilograms.
See Section 3.2.2 on page 13 for information about
configuring primary and secondary display units.

3.0Configuration
To configure the 390HE indicator, the indicator must
be placed in setup mode. The setup switch is accessed
by opening the enclosure cover and pressing the setup
switch mounted on the end of the pushbutton switch
board, next to the
ZERO button. Press the switch once
to enter setup mode, then close the cover and tighten
the cover screws.
When the indicator is placed in setup mode, the word
CONFIG is shown on the display. The CONFIG menu
is the first of seven main menus used to configure the
indicator. Detailed descriptions of these menus are
given in
Section 3.2. When configuration is complete,
return to the CONFIG menu and press the (ZERO)
key to exit setup mode.
3.1Configuration Methods
The 390HE 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 the EDP port. Configuration
using the menus is described in
Configuration using the EDP port can be accomplished
using either the EDP command set described in
Section 5.0 on page 22 or the Revolution™ configuration
utility.
3.1.1Revolution Configuration
The Revolution configuration utility provides the
preferred method for configuring the 390HE indicator.
Revolution runs on a personal computer to set
configuration parameters for the indicator. When
Revolution configuration is complete, configuration
data is downloaded to the indicator.
Section 3.1.3.
Revolution 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.
To use Revolution, do the following:
1. Install Revolution on an IBM-compatible
®
personal computer running Windows
3.11 or
Windows 95. Minimum system requirements
are 8MB of extended memory and at least
5MB of available hard disk space.
2. With both indicator and PC powered off,
connect the PC serial port to the RS-232 pins
on the indicator EDP port.
3. Power up the PC and the indicator. Use the
setup switch to place the indicator in setup
mode.
4. Start the Revolution program.
Figure 3-1 shows an example of one of the Revolution
configuration displays.
Revolution 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
Revolution: the interface is different, but the
parameters set are the same.
3.1.2EDP Command Configuration
The EDP command set can be used to configure the
390HE indicator using a personal computer, terminal,
or remote keyboard. Like Revolution, EDP command
configuration sends commands to the indicator EDP
port; unlike Revolution, EDP commands can be sent
using any external device capable of sending ASCII
characters over a serial connection.
EDP commands duplicate the functions available
using the indicator front panel and provide some
functions not otherwise available. EDP commands can
be used to simulate pressing front panel keys, to
configure the indicator, or to dump lists of parameter
settings. See
Section 5.0 on page 22 for more
information about using the EDP command set.
