Hardy 1734-WS Installation & Operation Manual
Page | 7
Product Description
HI1734-WS Weigh Scale Modules are self-contained, microprocessor-based I/O modules that produce weight
data when connected to strain gauge load sensors (load cells, load points, platform scales), and are plugged
into an Allen-Bradley Point I/O System.
The Allen-Bradley Point I/O® manual contains useful information about POINT I/O products that is not
provided in this manual. This manual assumes that users have a basic understanding of process control and
can interpret ladder logic instructions as needed to generate the electronic signals that control their
application(s).
The HI1734-WS Weigh Scale Modules 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 analog-to-digital converter in the weighing module controller updates 55 times per second and is capable
of up to 8,388,608 counts of resolution. This is enough to provide accurate weight measurement and control
and tolerate large “dead” loads or over sizing of load sensors.
Waversaver®
During the measurement of small weight changes, the effects of mechanical vibration and noise from the
operating environment can introduce substantial interference. Waversaver factors out vibration, noise, and
other interference-related signals from the load cell so the rate controller can better compute the actual
weight data.
Waversaver® can be configured 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 1.0 Hz vibration frequency immunity. The five cutoff frequencies are: 0.25Hz, 0.5Hz,
1Hz, 3.5Hz and 7.5Hz.
C2® Calibration
Traditional calibration uses certified test weights. C2® Electronic Calibration allows a scale to be calibrated
without the need for test weights.
A C2 weighing system consists of up to eight C2 load sensors, a junction box, interconnect cable, and an
instrument with C2 capabilities. Each Hardy C2-certified load sensor outputs digital information used for the
calibration. The modules read the sensor outputs and detect the number of active sensors. It then calibrates the
scale based on the load sensor’s output plus a user-supplied reference point value (from 0 to any known weight
on the scale).

IT
INTEGRATED TECHNICIAN™ (IT) is a system diagnostics utility which, in conjunction with an HI 6010IT (with up to
4 load sensors) or HI 6020IT (with up 4 load sensors per 6020IT card, and up to 2 6020IT cards) junction boxes,
allows the user to read individual load sensor voltages and weights and isolates individual system components for
quick and easy troubleshooting.
If you do not have the HI 6020IT or HI 6010IT Junction Box connected to the module, the mV/V reading is
displayed as the total for all the load sensors on the system.
Return to Zero Test – Optional
This test requires the HI 6020IT or HI 6010IT Series Junction Box to monitor individual load sensors. It compares
the original voltage reading (saved at calibration) against the current voltage reading of an empty vessel. 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.
NOTE: The HI 1734-WS IS compatible with the Hardy HI 6020IT, HI 6020JB HI 6010 IT or HI 6010JB. You
must use the HI 6020IT or the HI 6010IT to run this particular test. The HI 1734-WS is not
compatible with the Hardy HI 215IT Junction Box. It is compatible with the HI 215JB without the
IT functions.
Weighing System Test – Optional
For full utilization, this test requires the HI 6020IT or the HI 6010IT Series Junction Box. The Weighing System
test is used to diagnose drifting or unstable weight reading problems. The Weighing System Test does the
following:
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.
Auto Zero Tracking
Auto Zero Tracking automatically adjusts for zero weight. This capability allows the module to ignore material
build-up in the weighing system within a pre-set auto zero tolerance. For auto zero to work, the current gross
weight must be within the auto zero tolerance. The current gross, plus any previously zeroed weight must be
within the Zero Tolerance level value and the scale must not be in motion. This is not used on all applications
and should be reviewed before use.
NOTE: The amount of weight zeroed off is cumulative. The Auto Zero command will not run if the current gross
weight plus any previously zeroed amount exceeds the zero tolerance value.
