Chapter 1 - Overview CHAPTER 1 - OVERVIEW A BRIEF DESCRIPTION OF CHAPTER 1 This manual provides the user and service personnel with a description of the specifications, installation, setup, configuration, operation, communication, maintenance, and troubleshooting procedures for the Hardy Process Solutions HI 1746-WS Weigh Scale Module, designed for use in Allen-Bradley’s SLC 5/ 02, 5/03, 5/04, 5/05 programmable controllers.
HI 1746-WS WEIGH SCALE MODULE should understand process control and be able to interpret ladder logic instructions necessary to generate the electronic signals that control your application(s). 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 Specifications.
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.
HI 1746-WS WEIGH SCALE MODULE measurement applications. By eliminating the factor of vibratory forces the module is capable of identifying 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 frequency immunity.
Chapter 1 - Overview Digital Volt Meter (DVM) - Optional NOTE: 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.
HI 1746-WS WEIGH SCALE MODULE leveling and load sharing adjustments to the weighing system. The Hardy Configuration Software is highly recommended for use with this option. 1-6 Auto Zero Auto Zero Tracking will indicate zero weight, as long as any “live weight” on the scale is below the set Auto Zero Tolerance and the scale is not motion. This capability allows the module to ignore material build-up in the weighing system within a pre-set auto zero tolerance.
Chapter 2 - Specifications CHAPTER 2 - SPECIFICATIONS A Brief Description of Chapter 2 Chapter 2 lists the specifications for the HI 1746-WS Weigh Scale Module. Specifications are listed for the standard instrument and for optional equipment. The specifications listed are designed to assist in the installation, operation and troubleshooting of the instrument.

Remote Mode of Operation Type of Device Category: Other I/O Card ID Code: 3535 Input Words: 8 Output Words: 8 About M Files The M File Interface consists of two files, M0 and M1. M0 and M1 files are data files that reside in the HI 1746-WS Weigh Scale Module. There is no image for these files in the processor memory.
HI 1746-WS WEIGH SCALE MODULE NOTE: After making the change, you need to save the change to non-volatile memory. Changes can be made one word at a time or up to 37 words (all parameters) at a time. NOTE: If multiple words written to the module at the same time, data must be in the same order and have the correct length for each parameter.
Chapter 4 - Setup Remote Mode of Operation NOTE: For 1746 modules used in the remote chassis, direct mapping of the parameters to the M files is also available. You can write to a specific location in the M0 file, do a single Executable command, such as command 4 to write non-volatile, and the 1746 will pick up the change and apply it to the weigh module and reflect the change in the M1 file. After making the change you need to save it to nonvolatile memory.
HI 1746-WS WEIGH SCALE MODULE 2 3 4 5 Command Status indicates if the command succeeded or not. The module writes a value of zero (0) if the command succeeded. If the command failed, the module writes an error code value which indicates the reason for the command failure. (See the Error Code List.) The Error Code table also lists the commands where the error code is the sum of possible error bits. Offset specifies which parameter will be read or written.
Chapter 4 - Setup FIG. 4-2 PRIMARY AND REMOTE COMMUNICATION DIAGRAM Command Word Encoding You may write up to 7 words at a time to either the Logical O file or the Logical M0 file. Word #0 of the 8 word output file is used to specify where words 1-7 go in either the logical O or M0 file, is called the “Command Word”. Word #0 of the I file will always be a copy of the “Command Word”. Bits 15 & 14 11 = write 0 to 7 words to the logical M0 file, Read 7 words from the M1 file.
HI 1746-WS WEIGH SCALE MODULE Command Word - 16 bits Configure the Read and Write Writing to the 32 Word Logical O and logical M0 files Binary value indicating number of words to write Binary value indicating starting offset for write/read to begin. You must Decide whether you are going to write to the M0 or O file.
Chapter 4 - Setup Reading from the 32 Word Logical I and logical M1 files Reads are all done in the I file (not to be confused with the “logical I file”). Word #0 will always be a copy of the “Command Word”. Words 1-7 of the I file can be configured to read up to 7 words from either the Logical M1 or the Logical I file (you cannot read from both at the same time).

This means that nothing is draped across the scale/vessel or the load cell, such as a hose, electrical cord, tubes, or other objects. Check to see that nothing is coming in contact with the scale/vessel other than service wires and piping that have been properly mounted with flexible connectors. FIG.
Chapter 5 - Calibration b. c. d. e. The expected output from each load cell/point depends on the mV/V rating of the load cell/point and the weight. For example, a 2mV/V load cell/point will respond with a maximum of 10 mVDC at full weight capacity of the system which includes the weight of the vessel and the weight of the product as measured by the load cell/point. If the load cell/point weight capacity is rated at 1000 pounds, the load cell/point will be 10 mVDC at 1000 pounds, 7.
HI 1746-WS WEIGH SCALE MODULE f. Based on the example, the operating range for this scale is 5-10 mVDC with a 500 pound weight range. Understand that after zeroing the instrument, the 0 reading refers to the zero reference point and not absolute 0 mVDC or absolute 0 weight. NOTE: Load cell/point measurements are checked with a digital volt meter at the J2 connector on the front of the module or by using INTEGRATED TECHNICIAN with the HI 215IT Junction Box.
