through an Allen Bradley 1734 POINT I/O chassis.
This Quick Start Guide is designed for users of the HI 1734-WS module
that have a high degree of familiarity with Allen Bradley 1734 POINT I/O
systems and Hardy Process Solutions products. The Quick Start Guide
provides basic procedures for installing, configuring, and operating a
HI1734-WS POINT I/O Weigh Scale Module.

Notes:
CAUTION: UNPACK WITH CARE
PARTS ARE STATIC SENSITIVE!
Observe the following handling precautions:
xWear an approved wrist-strap grounding device when handling
the module
xTouch a grounded object to rid yourself of any electrostatic
discharge prior to handling the module
xHandle the module from the bezel in front away from the
connector. Never touch the connector pins.
xDo not install the module right next to an AC or high voltage DC
module
xRoute all the load voltage cables away from high voltage cables
WHEN UNPACKING, DO NOT DISCARD THE PACKING CASE OR ANY
PACKING MATERIAL UNTIL THE CONTENTS OF THE PACKING CASE ARE
INSPECTED AND CAREFULLY COMPARED WITH THE SHIPPING
DOCUMENTS.

Installation Procedure
The base (A) mounts onto the DIN rail and provides the backplane.
Bases and Terminal blocks are available from Allen Bradley. The
HI1734-WS module (B) snaps into the base, set the KEY position to 2.
The optional removable terminal block (C) also snaps into the base and
provides terminations for field-side connections, as well as system
power for the backplane.
For best performance, Hardy recommends use of 8-slot or 12-slot
screw-down terminals. Spring clamps are only recommended when
using solid-core wiring (not commonly used with sensors). 8-slot blocks
can only be used with 4 conductor load cells without sense lines.
Termination base assembly screw lock wire size range:
14 AWG-22 AWG, wire tightening torque: 7 lb-in [0.6nm] nominal.
Available backplane power and bandwidth can limit the number of
HI1734-WS modules connected together in a POINT I/O system. For
detailed installation instructions of a POINT I/O system, please visit:

Detailed specifications and power requirements for the HI1734-WS
module can be found in the Installation and Operation Manual.
Common Terms
AOP: Add-On-Profile.
Auto-Zero: Automatic zeroing of the scale as the gross weight nears
its last zero point, subject to the cumulative limit of the
Zero Tolerance parameter. Auto-Zero Tolerance is how
much the Auto-Zero function can adjust at one time.
C2®: C2® Electronic Calibration allows a scale to be calibrated
without the need for test weights. C2-certified sensors
output digital information used to automate the
calibration process.
Filter: Section used to stabilize weigh readings in an unstable
environment resulting from excessive vibrations or
occasional impact events.
WAVERSAVER eliminates unwanted noise from
mechanical vibrations and is typically set at 1.0 Hz.
NUMAVERAGES set the number of readings to average
to provide a stable weight during an impact event.
Gravity C2 load sensors are programmed to produce correct
Correction: weight at STANDARD GRAVITY. Use the Gravity
Correction parameter to adjust to your local
gravity (see Hardy’s website for a list of localized
correction factors).
Motion Tol: Choose the level of acceptable scale instability.
Ref. Weight: The amount of test weights used during Cal Low.
Sensitivity: The output signal in mV/V produced when the sensor is
100 percent loaded.
Span Weight: The amount of test weights used during Cal High.
Tare Weight: Difference between Gross Weight and Net Weight,
typically used to subtract the know weight of a vessel to
determine Net Weight of the vessel contents.
Zero Tol: Total allowable weight that can be zeroed from the
scale, with the initial zero point being established
during calibration.

Calibration
Select a calibration method and follow the steps below to calibrate the
scale system.
C2 – Electronic Calibration (also called eCAL)
1) Remove all weight from the scale.
2) Set gravity correction for the location of the weighing system
a. See users guide for the correct correction factor
3) Press C2 Cal.
4) Place a verification weight on the scale to ensure calibration is
successful.
Hard Cal- Traditional Calibration
1) Verify that the Reference Weight and Span Weight have been
set correctly in the configuration tab.
2) If Reference Weight=0, remove all weight from the scale.
3) Click Low CAL to set the low point on the calibration curve.
4) Place a physical Span Weight onto the scale equal to the
amount input into the configuration tab.
5) Press High Cal to complete the calibration process.
Wiring
CAUTION: Over tightening screw down terminal blocks can shear sensor
wires and cause intermittent or complete failure of the weighing
system.
The HI 1734-WS weigh scale module is connected to external load cells
or sensors using the terminal blocks. A single sensor can be connected
directly as shown in the above diagrams; a group of sensors are typically
connected through a Junction Box using the same pin-outs shown
above.
NOTE: THE HI1734 is not compatible with HI 215 Junction Boxes.
Please ensure that the HI1734 is installed with the HI6020IT or
HI 6020JB Junction Boxes.
Skip C2+ and C2- connections when using sensors NOT supplied by
Hardy Process Solutions. (C2® Electronic Calibration allows a scale to be
calibrated without the need for test weights.)
Further detail and diagrams for connecting various junction boxes,
sensors, load cells and alternate terminal blocks available from Allen
Bradley can be found in the Installation & Operations Manual.

Initial Set-Up
1. Once modules are installed and all connections are complete,
power up the system.
2. To make or change settings, there must be power to both the PLC
and the module. Verify that the LED’s are lit for normal operation.
LED Light Status
Steady Green Running (Normal)
Flashing Green Error No Calibration
Steady Red Error Read Failure or Error EEPROM Write
Flashing Red Read Convert Error
See HI 1734-WS Installation & Operations Manual for
troubleshooting procedures related to Steady or Flashing Red LEDs
3. Set-up communications between the ControlLogix PLC and the
HI1734-WS Weigh Scale module. For detailed instructions, refer to
an RS Logix manual.
4. Search for the HI1734-WS AOP in RS Logix or download from the
Hardy website, located in Documents and Programs.
a. Install AOP into RS Logix by adding into the RS Logix project.
b. Double click AOP located in the RS Logix project tree to set-
up and configure HI1734-WS paramters.
5. In the General Tab of the AOP, select and name the 1734-WS
module to configure. Check Slot location.
6. Open the Configuration Tab and begin to follow the Suggested
Steps when setting up a module for the first time section of
this Quick Start Guide.
Suggested Steps When Setting Up a Module for the First Time
Set Up
1) Select Unit of Measure
2) Input Motion Tolerance
3) Input Zero Tolerance
4) Enable/Disable Auto-Zero Tracking
5) Input Auto-Zero Tolerance if applicable
Filter
1) Select Waversaver setting
2) Input Num Averages
Calibration
1) Choose a Calibration Method
a. C2 eCal
b. Hard Cal
2) Complete Calibration Procedure
Confirm
1) Click Apply to load parameters
Calibration Settings
1) Select Load Cell Sensitivity
2) Input Gravity Corr. (if using C2)
3) Input Reference Weight (if not using C2)
4) Input Span Weight (if not using C2)

7. Check Enable Copy Config. Table to download parameters set in the
AOP. These parameters become default in the event of a power
cycle and will over-write any changes that were done outside the
AOP (i.e.: those made in Ladder Logic or via a Faceplate).
8. Optional Faceplates and Add-On-Instructions for the HI 1734-WS
module are available on the Hardy Process Solutions website under
the Documents and Programs tab for the module.
