1.0 Introduction
The IQ plus 390-DC is a single-channel digital weight
indicator housed in a NEMA 4X/IP66-rated stainless
steel enclosure. The indicator front panel consists of a
1 in (25 mm), six-digit, liquid crystal (LCD) display
and six-button keypad. Features include:
• Drives up to four 350 Ω or eight 700 Ω 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
• Powered by 6 C batteries for complete
portability
• AC adapter for 115 or 230 VAC power
• Configurable standby mode limits indicator
power consumption when scale is inactive
• Piece count mode for basic parts counting
functions.
The IQ plus 390-DC is NTEP-certified for Classes III
and III L at 10,000 divisions. See Section 8.9 on
page 40 for detailed specifications.
1.1 Operating Modes
The IQ plus 390-DC 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 IQ plus 390-DC 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 28 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, remove the large fillister
head screw from the enclosure backplate. Insert a
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 IQ plus 390-DC indicator. Like
setup mode, test mode is entered using the setup
switch. See Section 8.7 on page 38 for more
information about entering and using test mode.
Standby mode
Standby mode is a configurable low-power mode
used to extend battery life when the indicator is
inactive. In standby mode, the LCD display shows
the word
STNDBY ; press any key to exit standby
mode. See Section 3.2.5 on page 19 for
information about configuring standby mode.
