About Hardy Manuals Every Hardy Installation and Operation manual is
organized into easily referenced chapters, that are
almost always the same:
• Chapter 1 - Provides an introduction to the
instrument and an Overview of the equipment
and its capabilities.
• Chapter 2 - Provides a complete list of Specifi-
cations.
• Chapter 3 - Contains complete instructions
needed to install the HI 1769-WS (both standard
and optional equipment) and the Remote Termi
nation Assembly (-RTA)
• Chapter 4 - Provides complete hardware Con-
figuration instructions for setting dip switches
and jumpers.
• Chapter 5 - Provides all Calibration instructions.
• Chapter 6 - Pertains to the Troubleshooting
procedures for repair of the instrument.

Description The HI 1769-WS & HI 1769-2WS Weigh Scale Mod-
ules are self-contained, microprocessor-based ControlLogix I/O modules with control inputs and
outputs, that is designed to be easily plugged into an
Allen-Bradley CompactLogix or MicroLogix 1500
programmable controller The HI 1769-WS Weigh
Scale Module is a single channel module while the
HI 1769-2WS is configured for dual operation which
1-2

Chapter 1 - Overview
can be used for a wide variety of process weighing
applications such as batching, blending, filling/dis
pensing, check weighing, force measurement, level by
weight and weight rate monitoring. The analog to dig
ital converter in the weigh module controller updates
one hundred (100) times per second and is capable of
8,388,608 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 module calibration is electronic
via C2 electronic calibration. C2 or Hard (Traditional
calibration with weights) is also available for those
not using Hardy C2 certified load sensors.
-
WAVERSAVER
®
Typically, mechanical noise (from machinery in a
plant environment) is present in forces larger than the
weight forces trying to be detected by the module.
The HI 1769-WS & HI 1769-2WS 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 identifying 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 pro
vide a faster instrument response time. The default
factory configuration is 1.00 Hz vibration frequency
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 as long
as power requirements don’t exceed specification. All
Hardy C2 certified load sensors contain digital infor
mation detailing its unique performance characteristics. The modules read the performance
characteristics of each individual load sensor and
-
-
1-3
HI 1769-WS/HI 1769-2WS WEIGH SCALE MODULE
detects the quantity of load sensors in the system. All
calibrations can be performed via ladder logic.
®
IT
INTEGRATED TECHNICIAN™ is a system diagnostics
utility. For full functionality the weigh system should
include an HI 215IT series junction box. Full IT func
tionality allows the operator to rapidly troubleshoot a
weighing system.
-
Digital Volt Meter (DVM) - Optional
Requires the HI 215IT Series Junction Box to monitor
both and mV/V readings for the system and per indi
vidual load sensor. Once a problem is detected by the
operator the DVM readings help the operator to iso
late the faulty component. Further, the DVM readings
can be used to level a system and to make corner
adjustments to platform scales. Accuracy is +/- 2% or
better of full scale.
NOTE: If you do not have the HI 215IT Junction Box con-
nected to the module, the mV/V reading as displayed
is the total for all the load cells on the system.
Rate of Change The ROC option measures and displays the rate at
which a material enters or is dispensed from the scale
over a period of time. ROC data uses a 100-entry reg
ister. New weight values are written to the register at
the rate of 1/100th of the time base. The first register
is subtracted from the 101st Register, which is one
time base older than the first register. The ROC is
reported in units per minute. A time base of discrete
values is selectable from 1 to 1800 sec
Return to Zero Test - Optional
Requires the HI 215IT Series Junction Box to monitor
individual load sensors. This test compares the origi
nal 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 bind
ing on one or all of the load sensors in the system.
-
-
-
-
-
Weighing System Tests - Optional
1-4
Requires the HI 215IT Series Junction Box for full
utilization. This test is used to diagnose drifting or
unstable weight reading problems. The Weighing Sys
tem Test does the following:
-
Chapter 1 - Overview
1. Disconnects the controller and engages an inter-
nal reference signal to see if the problem is within
the instrument.
2. 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.
3. 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 indicates zero weight, as long as
any “live weight” on the scale is below the set Auto
Zero Tolerance, this function is turned on and the
scale is not in motion. This capability allows the mod
ule to ignore material build-up in the weighing system
within a pre-set auto zero tolerance.
