1.0 Introduction
The 420HE is a single-channel digital weight indicator housed in a NEMA 4X/IP66-rated FRP enclosure. The
indicator front panel consists of a large (1.8 in, 44.5 mm), six-digit, seven-segment LED display and six-button
keypad. Features include:
• Drives up to eight 350or sixteen 700 load cells
• Supports 4- and 6-wire load cell connections
• Two configurable digital inputs
• Two configurable digital outputs
• Electronic data processing (EDP) port for full duplex, RS-232 communications at up to 38400 bps
• Printer port for full duplex RS-232 or active transmit only 20 mA current loop communications at up to
38400 bps
• Optional analog output module provides 0–10 VDC or 0–20/4–20 m A tracking of gross or net weight
values
• Available in 115 VAC and 230 VAC versions
The 420HE is NTEP-certified and pending Measurement Canada approval for Classes III, III HD, and III L at
10,000 divisions. See
1.1 Operating Modes
The 420HE has four modes of operation:
Normal (Primary) mode
Normal mode is the “default” mode of the indicator. The indicator displays gross or net weights as required,
using the LED annunciators described in Section 1.3 on page 3 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, this is
the primary mode in which the 420HE can operate.
Section 7.12 on page 49 for detailed specifications.
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 enclosure 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 420HE indicator. Like setup mode, test mode is
entered using the setup switch. See
test mode.
NOTE: Test mode is intended for factory use only.
Front Panel Setup Mode
Hold the UNITS key for three seconds to enter front panel setup mode. Use front panel setup to change
setpoint and to set the time and date.

2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the
420HE to ensure all components are included and
undamaged. The shipping carton should contain the
indicator, this manual, and a parts kit. If any parts were
damaged in shipment, notify Rice Lake Weighing
Systems and the shipper immediately.
The parts kit (PN 87973) contains the items listed

2.3 Cable Connections
The 420HE provides four cord grips for cabling into the
indicator: one for the power cord, three to
accommodate load cell, communications, digital
inputs, and analog output cables. Two of the three free
cord grips come with a plug installed to prevent
moisture from entering the enclosure. Depending on
your application, remove the plug from any cord grip
that will be used and install cables as required.
Figure 2-1 shows the recommended assignments for
420HE cord grips.

Except for the power cord, all cables routed through the
cord grips should be grounded against the CPU
mounting plate. Do the following to ground shielded
cables:
• Use the lockwashers, clamps, and kep nuts
provided in the parts kit to install grounding
clamps on the enclosure studs adjacent to cord
grips. Install grounding clamps only for cord grips
that will be used; do not tighten nuts.
• Route cables through cord grips and grounding
clamps to determine cable lengths required to
reach cable connectors. Mark cables to remove
insulation and shield as described below:
• For cables with foil shielding, strip insulation and
f
oil from the cable half an inch (15 mm) past the
grounding clamp (see Figure 2-2). Fold the foil
shield back on the cable where the cable passes
through the clamp. Ensure silver (conductive) side
of foil is turned outward for contact with the
grounding clamp.
• For cables with braided shielding, strip cable
in
sulation and braided shield from a point just
past the grounding clamp. Strip another half inch
(15 mm) of insulation only to expose the braid
where the cable passes through the clamp (see
Figure 2-2).
• For load cell cables, cut the shield wire just past
the
grounding clamp. Shield wire function is
provided by contact between the cable shield and
the grounding clamp.
• Route stripped cables through cord grips and
cla
mps. Ensure shields contact grounding clamps
as shown in Figure 2-2. Tighten grounding clamp
nuts.
• Finish installation using cable mounts and ties to
secur
e cables inside of indicator enclosure.

2.3.2 Load Cells
Note
Using one of the 6-position connectors, provided in the
parts kit, wire the load cell cable from the load cell or
junction box to connector J1 on the CPU board (See
Figure 2-3 7). If using six-wire load cell cable (with
sense wires), remove jumpers JP1 and JP2 before
reinstalling co
four-wire installation, leave jumpers
nnector J1 (see Figure 2-3). For
JP1 and JP2 on.
When connections are complete, reinstall connector J1
onto the header so that it snaps securely into place. Use
two cable ties to secure the load cell cable to the inside
of the enclosure.

2.3.3 Serial Communications
Using one of the six-position connectors, provided in
the parts kit, wire the serial communications cables to
J4. Connector J3 provides connections for the EDP/
RS-232 port. Connect communications cables to
connectors J3 and J4 as shown in Table 2-2.
Once cables are attached, reconnec
t J3 and J4 to the
headers on the board (see Figure 2-3). Use cable ties to
secure serial cables to the inside of the enclosure.
The EDP port supports full duplex RS-232
communications only; the
serial port provides either
active 20 mA output or full duplex RS-232. Both ports
are configured using the SERIAL menu. See

are active (on) with low voltage (0 VDC) and can be
driven by TTL or 5V logic without additional
hardware. Use the DIG IN menu to configure the
digital inputs. LED’s on the CPU board light when
digital inputs are active.
Digital outputs are typically used to
control relays that
drive other equipment. Outputs are designed to sink not
source, switching current. Each output is a normally
open connector circuit, capable of sinking 250 mA
when active. Digital outputs are wired to switch relays
when the digital output is active (low, 0 VDC) with
reference to 5 VDC supply. LEDs on the CPU board
light when the digital outputs are active.

for opening the
420HE enclosure.
Mount the analog output module on its standoffs in the
location shown in Figure 2-3 7 and plug the module
input into connector J9 on the
420HE board. Connect
output cable to the analog output module as shown in
Table 2-4, then reassemble the enclosure (Section 2.5).
See Figure 7.8 46 for analog output calibration
procedures.

3.0 Configuration
T o configure the 420HE indicator , the indicator must be
placed in setup mode. The setup switch is accessed by
opening the enclosure and pressing the setup switch.
When the indicator is placed in setup mode, the word
CONFIG is shown on the display. The CONFIG menu is
the first of ten main menus used to configure the
indicator. Detailed descriptions of these menus are
given in Section 3.2 on page 15. When configuration is
complete, return to the CONF
IG menu and press the
(ZERO) key to exit setup mode.
3.1 Configuration Methods
The 420HE 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 Section 3.1.3 on
page 14.
Configuration using the EDP port can be accomplished
ing either the EDP command set described in
us
Section 5.0 or the

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.
3.1.2 EDP Command Configuration
The EDP command set can be used to configure the
420HE 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 fu
nctions 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 29 for more information about
using the EDP command set.

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.
