1.0 Introduction
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 350 Ω 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.
1.1 Operating 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 Section 1.3 on page 2 to indicate
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.
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
CONFIG
.
Test mode
Test mode provides a number of diagnostic
functions for the 390HE indicator. Like setup
mode, test mode is entered using the setup switch.
See Section 8.7 on page 36 for more information
about entering and using test mode.
