Installation and Wiring 5
Use only Factory Mutual Approved cables.
Conduit System (Supplied by Customer)
AC Line Voltage Feed:
The power supply AC line
voltage feed must be run through conduit and be
properly sealed. The installer must comply with
RLWS installation drawings as well as the National
Electrical Code for installation of equipment in
hazardous areas (NEC Article 504, Intrinsically Safe
Systems ).
Power Supply to Indicator:
Conduit is not required for
this installation. However, a separate conduit system
is recommended. The type suggested for this
application is 3/4 inch rigid steel conduit with pull
boxes located at required intervals. The conduit
provides additional noise protection for the low level
signals, while automatically complying with the
requirements for 2 inch separation between
intrinsically safe circuits and other electrical cables.
Conduit seals are required where a gas tight seal is
required between the hazardous area and the safe area.
To protect the watertight integrity of the I/O barrier
and junction box, the conduit should terminate
adjacent to the respective enclosure with a union
providing the proper thread to accept a Hubbel or
Crouse Hinds cord connector for the cable to exit the
conduit. All conduit, fittings and conduit accessories
are provided and installed by the customer.
NOTE:
The customer is responsible for the correct
installation of all conduit seals in compliance with all
National Electrical Code regulations.
2.3 AC Power Wiring
Standard units are powered by one of these two
options:
•115 VAC into RLWS DC output power supply
(RLWS PN 33476)
•230 VAC into RLWS DC output power supply
(RLWS PN 33477)
2.4 Battery Option
The optional battery package provides an intrinsically
safe battery pack that can replace the power supply.
The battery is approved for use in hazardous
environments and provides up to 50 hours of
continuous operation in a four by 350
Ω load cell
system. The battery pack is ideal for limited use
operations such as bench scales and platform scales.A
low battery LED annunciator indicates when the
battery needs to be recharged (see Figure 2-2). The
recommended initial battery charge time is 14 hours.

The battery pack is designed for easy removal and can
be recharged in a safe area in 8 hours or less. The
indicator also contains an auto shutoff to power off the
indicator when not in use. An optional battery charger
is available from RLWS.
All wiring must be done by qualified
personnel and meet all appropriate
safety and NEC electrical codes as
noted on RLWS Control Drawing
33476.
2.5 Instrumentation Setup
All indicators are configured and tested prior to
shipment to ensure that they are fully functional. The
unit can be turned on immediately after connecting the
input power and the load cells.
The IQ 700IS operates with the EPROM program
KDA--49 (27C512). To verify the program installed in
the indicator, turn on the indicator and observe the
displayed value at the EP prompt (see Figure 2-3).
The EP prompt displays the family, set, and version
level of the installed EPROM.
Figure 2-3. Example of EPROM Display
To ensure that the IQ 700IS is in proper operating
condition, the indicator can be tested in a safe area
with a load cell simulator. The input signal should be
as close as possible to the normal system millivolt
value. Figure 2-4 shows the simulator-to-indicator
wiring connection in a six-wire configuration. See
Section 2.6 on page 7 for more information.
NOTE:
Six-wire configuration requires that the +SEN
lead be jumpered to +EXC and the –SEN lead be
jumpered to –EXC at the simulator only.
Figure 2-4. Wiring Connection to Simulator
Exceeding rated load cell load or
shortening excitation wires may
damage power supply.
NOTES:
•Test weights or a water meter calibration can
be used to verify scale performance.
•The tilt stand should be secured with 1/4-20
inch screws. The location should be selected
to offer some degree of protection for the
indicator and its associated hardware.
•Unprotected cable runs need to be installed in
a method to protect the cable from damage.
•All wiring must conform to the National
Electrical Code and RP 12.6.
See control drawing 33476, Sheet 2, in the back of this
manual for system interconnection details.

Serial Port 1 is a bidirectional (full duplex) port
supporting active 20 mA current loop
communications. Port 1 is optically isolated through
the intrinsically safe I/O barrier.
The IQ 700IS serial port can be configured to
communicate directly to a printer, remote display, or
other device using 20 mA communications through
the I/O interface barrier (see Figure 2-8). Since the I/O
barrier is not powered (totally passive), the receiving
device must also provide an active 20 mA current loop
interface to retrieve data from the I/O barrier.
Figure 2-8. Intrinsically Safe System using Serial
Communications
NOTE:
The serial communications capability of the IQ
700IS is dependent on the product specifications of the
receiving device. All serial communications applications
should be tested with the I/O barrier in place.
Access to this serial communication port is through
the five-pin female connector (J3) located on the back
of the IQ 700IS indicator (see Figure 2-9). See the
output connector diagram in Figure 2-9 and Table 2-5
for connector and wire identification.

3.0 Configuration
Prior to calibration, the IQ 700IS must be digitally
configured, or assigned a set of operating parameters.
The first three parameters are directly related to
calibration and must be set before proceeding to
calibration mode.
3.1 Digital Configuration
3.1.1 Parameter Overview
Table 3-1 on page 10 lists configuration parameters
and describes their values. The following paragraphs
give the procedure for configuring the IQ 700IS.
3.1.2 Configuration Procedure
1. Unscrew the two screws on the face plate
bracket (See Figure 3-1). The bracket drops
down, exposing four program switches on the
left.
Figure 3-1. Accessing the Program Switches
2. Temporarily remove the unit’s flexible black
display panel by gently pushing down and
lifting the panel up and out at its center to
expose the configuration and calibration
instructions printed on the surface below. The
switch function table defines the appropriate
front panel switch settings for the CONF and
CAL modes.
3. Close switch SW1-2, marked CONF (2), by
moving to the up position (see Figure 3-2). A
prompt appears with a parameter number and
data value.
The parameter identifier is a number, 1–14, that
correlates to the CONFIG chart on the upper left of
the switch map panel. Selected data represents the
value being entered into the unit configuration data.
For example, 1 100 sets the indicator to 10,000
graduations (see Table 3-2 on page 10).
When configuration is complete, set SW1-2 open
(down) to return the unit to normal operating mode.
Figure 3-2. Closing Switch 2
The function keys shown in the table in Figure 3-3
have alternate functions during digital configuration.
Figure 3-3. Front Panel Key Functions
NOTE: The TARE RECALL key functions as a
previous screen key in CONFIG mode.
3.1.3 Digital Configuration Parameters
Table 3-2 on page 10 lists the configuration display
prompts (Prompt 1) and their value selections for
displayed graduations. Prior to calibration, the IQ
700IS must be digitally configured, or given its set of
operating parameters. The first three parameter
selections are directly related to calibration and must
be set up before proceeding to the calibration mode.
These parameters include the number of graduation,
the resolution, and the decimal point location in the
weight data, all of which define the scale capacity.
Table 3-3 lists Prompts 2 and 3 and Table 3-4 has
Prompts 5, 6, and 7. Prompts 8, 9, and 10 are shown in
Table 3-5 and Prompts 11 through 14 are listed in
Table 3-6.

3.3 Options Configuration
The IQ 700IS offers a selection of optional features
that are available in the configuration of the indicator.
The options setup mode allows the operator to expand
the capabilities of the indicator. The available options
are:•Option 1 - Expanded resolution
•Option 2 - Analog output
•Option 3 - Time and date
•Option 4 - Auto shutoff
•Option 6 - Five-point linearization
•Option 7 - Smart serial I/O
To access digital option configuration, close switches
SW1-2 and 1-3 (Figure 3-4). If the option mode has
been enabled, selections are available. If the option
mode is not enabled (all options turned off), dashes
appear across the display (- - - - -). Press and hold the
ENT key until OPtion appears on the display.
Figure 3-4. Close Switches SW1-2 and 1-3 for
Option Configuration
In the option mode, primary function keys (ZERO,
GROSS/NET, etc.) operate as secondary function keys
(Figure 3-5).
Figure 3-5. Front Panel Keys with Alternate
Functions in Options Menu
Use the ZERO key to select Options 1, 2, 3, 4, or 6 or
the TARE RECALL key to scroll backward through the
options. To enable a selected option, use the
GROSS/NET key.
Some options, once enabled, may have an option
submenu available. Use the TARE key to access the
option submenu. To make parameter selections in the
Option submenu, use the UNITS key. Display
prompting is provided in each case.
Key Functions Summary
Use the list below as a quick reference when selecting
and configuring the options.
3.3.1 Option 1 – Expanded Resolution
Enabling Option 1 increases the indicator resolution
by allowing display graduation selections beyond the
normal 20,000 in Parameter 1 of the configuration
mode.
Up to 80,000 displayed graduations are available
when this option is on; however, applying such high
gains to the data may cause undesirable display
instability in some applications.
The expanded resolution (OP.1) is shown in Table 3-8.
3.3.2 Option 2 – Analog Output
Option 2 converts serial data into 0–10 Vdc or 4–20
mA analog output. The analog output tracks gross,
net, or displayed weight and includes automatic
checking and verification.

Configuration 17
3.3.4 Option 4 – Auto Shutoff Mode
The auto shutoff mode can prolong battery life for
applications using the battery input power to the
indicator.
Option 4 allows the indicator to be configured to shut
off automatically when idle for a specified time (1–9
minutes). Parameter 4.2 can be enabled to reset the
shutoff timer if motion is detected on the scale after
the timer is started.
Option 4 is not a “sleep mode”; once the indicator
shuts off, it must be turned on again. With Option 4
enabled, the on/off switch becomes active (see
Figure 3-6) and can be used to restart the unit.
NOTES:
•Option 4 requires hardware setup inside the
indicator enclosure and must be enabled at the
factory.
•Option 3 (time and date) must be enabled and
set to use Option 4.
Prompts for auto shutoff mode (OP.4) are shown in
Table 3-11.
