Description The HI 1746-WS Weigh Scale Module is a self con-
tained microprocessor based I/O module with control
inputs and outputs, that is designed to be easily
plugged into the back plane of an Allen-Bradley SLC
5/02, 5/03, 5/04 or 5/05 programmable controller and/
or Remote Rack. The HI 1746-WS Weigh Scale Mod
ule can be configured to operate as either a local or

Chapter 1 - Overview
remote module. The HI 1746-WS module can be used
for a wide variety of process weighing applications
such as batching, blending, filling/dispensing, check
weighing, force measurement, level by weight and
weight rate monitoring. The module can control two
(2) relays via two (2) TTL level outputs and transmits
data via the back plane to the SLC. The 20 bit analog
to digital converter in the weigh module controller
updates twenty (20) times per second and is capable
of 985,000 counts of display resolution. This gives the
instrument the ability to tolerate large “dead” loads,
over sizing of load cells/sensors and still have suffi
cient resolution to provide accurate weight measurement and control. The HI 1746-WS module is set up

T ypically, mechanical noise (from other machinery in
a plant environment) is present in forces larger than
the weight forces trying to be detected by the module.
The HI 1746-WS is fitted with WAVERSAVER

technology which eliminates the effects of vibratory
forces present in all industrial weight control and

measurement applications. By eliminating the factor
of vibratory forces the module is capable of identify
ing the actual weight data. WAVERSAVER® can be
configured from the Configuration Software to ignore
noise with frequencies as low as 0.25 Hz. One of five
higher additional cut off frequencies may be selected
to provide a faster instrument response time. The
default factory configuration is 1.00 Hz vibration fre
quency immunity.
C2® Calibration C2 Second Generation Calibration enables a scale
system to be calibrated electronically without using
certified test weights which equals the systems load
capacity. A C2 weighing system consists of up to
eight (8) C2 load sensors, a junction box, interconnect
cable and an instrument with C2 capabilities such as
the HI 1746-WS Weight Scale Module. All Hardy C2
certified load sensors contain digital information
detailing its unique performance characteristics. The
HI 1746-WS reads the performance characteristics of
each individual load sensor and detects the quantity of
load sensors in the system. C2 Calibration can be per
formed by pressing “The Button” located in the front
of the module, or via Hardy’s Configuration Software
or Allen-Bradley’s RS Logix 500 software.

IT® INTEGRATED TECHNICIAN™ is a system diagnostics
utility which continuously monitors the weighing sys
tem (with up to 4 load sensors) for possible malfunctions. For full functionality the HI 215IT junction box
and Hardy’s Configuration Software for Windows
should be used. Full IT functionality allows the opera
tor to rapidly troubleshoot a weighing system from
the Configuration Software, I
CIAN Display.
NTEGRATED TECHNI-
Excitation Monitor Continuously monitors a system’s excitation current
to check for open or shorted load sensors or damaged
or broken excitation wire(s), including the wires
between the module and the IT Junction box. If the
measured current deviates more than a +/- 10% toler
ance, an “Excitation Error” bit (Module Status Word
bit 9) is set to 1.

Return to Zero Test - Optional
Requires the HI 215IT Junction Box and Hardy Configuration Software to monitor both mV and mV/V
readings per individual load sensor. Once a problem is
detected by the operator the DVM readings help the
operator to isolate the faulty component. Further, the
DVM readings can be used to level a balanced system
and to make corner adjustments to platform scales.
Accuracy is +/- 2% or better of full scale.
nected to the module, the mV/V reading as displayed
in the Configuration Software, T e st display is the total
for all the load cells on the system.
Requires the HI 215IT Junction Box to monitor individual load sensors. The Hardy configuration Software is required when using this option. This test
compares the original voltage reading (saved at cali
bration) against the current voltage reading of an
empty vessel. The test displays a “Passed Return to
Zero T est” or a “Failed Return to Zero T est” s tatement
when running the System Test from the Configuration
Software, Test Display, depending on the outcome of
the test. The test checks for damaged load sensors due
to electrical zero shift or abnormal mechanical forces
that cause binding on one or all of the load sensors in
the system.
-
Weighing System Tests - Optional
Requires the HI 215IT Junction Box. This test is used
to diagnose drifting or unstable weight reading prob
lems. The Weighing System Test does the following:
1. Disconnects the controller and engages an inter-
nal reference signal to see if the problem is within
the instrument.
1. Disconnects the load sensors and engages an
internal (in the junction box) reference signal to
see if the cable between the instrument and the
Junction Box is causing the problem.
2. Reads the weight of each load sensor to see if the
load sensor might be causing the problem.
The ability to read the weight seen by each individual
load sensor allows use of this test to make cornering,

leveling and load sharing adjustments to the weighing
system. The Hardy Configuration Software is highly
recommended for use with this option.
Auto Zero Auto Zero Tracking will indicate zero weight, as long
as any “live weight” on the scale is below the set Auto
Zero T olerance and the scale is not motion. This capa
bility allows the module to ignore material build-up in
the weighing system within a pre-set auto zero toler
ance.
Note The amount of weight zeroed off is cumulative. The
zero command will fail if the current gr oss weight plus
any previously zeroed amount exceeds the zero
tolerance.

Set Point TTL Outputs
The HI 1746-WS is equipped with two (2) standard
Digital TTL (Transistor - Transistor Logic) Level
Outputs which can be connected to external solid state
relays. Both outputs have individual set point, preact
and deadband parameters. Both outputs are rated at 10
milliamps per line. Each can be programmed to
respond to the standard Net, Gross, Rate of Change
