1.0 Introduction
The Tracer AV is a single-channel digital weight
indicator comprised of three components:
• The Tracer AV houses the AC power supply
and CPU board. There are external DB-9
connectors for a PC connection, two remote
display connections, two remote keypad
connections, and a load cell connection (See
Figure 2-3 4).
• The RD-1 remote display (See Figure 1-1 2)
is a large .8 in., six-digit, seven-segment LED
display. There are connectors for two remote
displays.
• The RK-1 keypad (See Figure 1-1 2) has two
keys which are used to zero the scale and to
toggle between a primary and secondary unit
of measure in the normal mode of operation.
These keys have a secondary function for the
setup mode.
The Tracer AV features include:
• Four-wire load cell connections; remote sense
connections are not provided.
• The electronic data processing (EDP) port is
full duplex; RS-232 communications at up to
38400 bps. The EDP port is accessed through
the COMM connection.
• The serial port connects to the RD-1 remote
displays. The output is RS-232 and will drive
two RD-1 units.
• Print formatting is defaulted for RD-1
communications.
• Digital inputs are defaulted for RK-1
functionality.
• Setpoints values will cause the display to
flash when a specified weight value is
exceeded.
• Available for 115 VAC and 230 VAC.
1.1 Operating Modes
The Tracer AV has three modes of operation:
Normal (Primary) mode
Normal mode is the default mode of the Tracer AV .
The indicator displays gross or net weights as
required, using the LED 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, this is the primary mode in which the
Tracer AV can operate.
Setup mode
Most of the procedures described in this manual
require the
Tracer AV to be in setup mode,
including configuration and calibration.
To enter setup mode, remove the setup switch
access screw on the
Tracer AV (See Figure 2-3 4).
Once the screw is removed, use a small
screwdriver or pen tip to press the setup switch.
The display changes to show the word
DEFCAL .
Test mode
Test mode provides a number of diagnostic
functions for the
Tracer AV . Like setup mode, test
mode is entered using the setup switch. See
Section 6.7 on page 39 for more information.
NOTE: Test mode is intended for factory use only.
