Terms and  
Abbrevia-  
tions  
The following terms and abbreviations are used throughout this manual. For definitions of terms  
not listed here refer to Allen-Bradley’s Industrial Automation Glossary, Publication ICCG-7.1.  
Calibration - Procedure, performed by trained personnel, where machine or press is  
dynamically loaded to impact on load cells. A process of linearity measuring to determine the  
loading capacity of the machine.  
Calibration Number - Amplification values established during machine calibration or pre-  
assigned on force load cells.  
Channel - Refers to one of two, strain gage inputs available on the modules terminal block.  
Chassis - A hardware assembly that houses devices such as I/O modules, adapter modules,  
processor modules, and power supplies.  
Configuration Word - Contains the channel configuration information needed by the module to  
configure and operate each channel. Information is written to the configuration word through  
the logic supplied in your ladder program.  
Data Word - A 16-bit integer that represent the value of the analog input channel. The channel  
data word is valid only when the channel is enabled.  
Gain - Amplification of an input signal.  
Load/Force - Measurement of impact during a machine cycle. Sensors provide the input for  
this measurement.  
LSB - (Least Significant Bit) Refers to a data increment defined as the full scale range divided  
by the resolution. The bit that represents the smallest value within a string of bits.  
Remote Configuration - A control system where the chassis can be located several thousand  
feet from the processor chassis.  
Resolution - The smallest detectable change in a measurement, typically expressed in  
engineering units (e.g. 0.15C) or as a number of bits. For example a 12-bit system has 4,096  
possible output states. It can therefore measure 1 part in 4096.  
Sample - Load/force values established from a series of machine cycles. Also defined as  
benchmark.  
Sampling time - The time required by the A/D converter to sample an input channel.  
Scale - Value used to describe the press/machine overall tonnage. Set for maximum value of  
one channel. For example, settings for a 150 ton press = 75.  
Status Word - Contains status information about the channel’s current configuration and  
operational state. You can use this information in your ladder program to determine whether  
the channel data word is valid.  
Update Time - The time required for the module to sample and convert the input signals of all  
enables input channels and make the resulting data values available to the SLC processor.

Chapter 1  
Overview  
You have just purchased the most advanced load monitoring solution  
available. HELM INSTRUMENT COMPANY, INC. manufactures a  
complete line of load monitoring control solutions for use on metal  
stamping, forging, compaction and assembly presses; cold forming, cold  
heating, injection molding and die cast machines.  
Standard or custom transducers and load cells are available for in-die  
monitoring of transfer or progressive tooling.  
At HELM, quality is inherent not only in the design of our products but in  
the attitudes of our employees as well. We’re working together to give  
you the best. After all, that’s what our business is all about - providing  
innovative instrumentation to help make your manufacturing process  
more productive and your operation more effective.  
The Helm Weigh Scale combines machine and tooling monitoring with  
programmable limit switch function. User programmable high and low  
limits protect the machine and tooling to ensure part quality.  
Critical setup information can be stored and uploaded as part of a die  
recipe program. An optional resolver input module is used to compare  
machine/press tonnage to crank angle for real time signature analysis.  
The Helm Weigh Scale module is attached to the controller or to an  
adjacent I/O module on the din rail. The system is comprised of two  
parts; the input module and two Helm Strain gage based sensors.  
Components  
The primary part of the load monitoring system centers around the  
measurement. The basic function of the Helm Strain Gain sensor is to  
detect the amount of deflection imposed on the press or die as parts are  
being formed. All Strain Gain sensors are matched to within 1% and  
therefore can be replaced without recalibration of the machine.  
Strain Gain  
Transducer  
Operation  
The Helm Strain Gain sensors can be mounted to strategic high stress  
areas of the machine frame or strategically located in tooling or applied  
to stop blocks. Signals from these sensors are routed to the Weigh  
Scale module for processing. The Helm Strain Gage is capable of  
measuring either a tension or compression  
signal.  
Page 1-1  
 
Chapter 1  
Hardware  
Overview  
The Weigh Scale module can be attached to the controller or to an  
adjacent I/O module before or after din rail mounting. It is a Class 1  
module (uses eight input words and eight output words). It interfaces to  
strain gage based transducers (350ohm or 700ohm).  
The module can accept input from two sensors. The module has no  
output channels. Module configuration requires manual and user  
programmable setup.  
The Weigh Scale module receives and stores digitally converted analog  
data into its image table for retrieval by processor. The module supports  
connections from any combination of up to two strain gage sensors.  
Any combination of Helm Strain Gage sensors can be used. Contact  
Helm for additional information on the type and application of different  
sensor options.  
Page 1-2  
 
Chapter 2  
Getting  
Started  
This chapter can help you to get started using the Helm Weigh Scale  
module. The procedures included here assume that you have a basic  
understanding of PLC products. You should understand electronic  
process control and be able to interpret the ladder logic instructions  
required to generate the electronic signals that control your application.  
Because it is a start-up guide, this chapter does not contain detailed  
explanations about the procedures listed. It does, however, reference  
other chapters in this book where you can get more information about  
applying the procedures described in each step. It also references other  
SLC documentation that may be helpful if you are unfamiliar with  
programming techniques or system installation requirements.  
If you have any questions or are unfamiliar with the terms used or  
concepts presented in the procedural steps, always read the referenced  
chapters and other recommended documentation before trying to apply  
the information.  
This chapter will:  
Tell you what equipment you need  
Explain how to install and wire the module  
Show you how to set channels for the sensor input  
Required Tools and Equipment  
Have the following tools and equipment ready:  
Small blade screwdriver  
Appropriate strain gage cable  
Programming equipment (All programming examples shown in this  
manual demonstrate the use of Allen-Bradley’s RS Logix 500.  
Page 2-1  
 
Chapter 2  
System  
Operation  
The Weigh Scale module communicates to the processor through the parallel  
backplane interface and receives +5Vdc and +24Vdc power from the power  
supply through the backplane. No external power supply is required. The  
MicroLogix and CompactLogix platforms can support up to 8 I/O modules. You  
may install up to 3 Weigh Scale modules using the base power supply. An  
additional power supply can be added to support more than 3 modules. Refer to  
publication 17864-UM100A-US-P for information on expansion power supply  
systems.  
Each individual channel on the module can receive input signals from strain gage  
based sensors. The module converts the analog values directly into digital  
values.  
Sensor  
Wiring  
The sensors are wired to the modules using the rightmost bank of inputs.  
The pin-out is shown below.  
To ensure proper operation  
and high immunity to  
electrical noise, always use  
Helm strain gage cable.  
The module can support up to  
two sensor inputs DO NOT  
attempt to parallel additional  
gages as you will cause  
damage to the module and void  
product warranty.  
To limit noise, keep strain gage cable as  
far away as possible from power and load  
lines.
