  • Page 17: Introduction

    CHAPTER Introduction This manual describes the installation and setup of the LaserSpeed 8500-4 gauge. For daily routine usage, see the LaserSpeed 8500-4 Operator Guide. The Model LS8500-4 LaserSpeed® Non-contact Length and Speed gauge is an industrial, Laser-Doppler based instrument that measures the velocity and length of material. Due to the nature of the laser-based measurement, there is no physical contact with the material.
  • Page 19: System Overview

    CHAPTER System Overview Description The Model LS8500-4 is a stand-alone instrument that requires only 24 VDC input power to operate. The sys- tem has a variety of industrial outputs. Also, a variety of information including length, velocity, system operat- ing parameters, and setup parameters can be read and configured using the communications interfaces. The LS8500-4 is permanently calibrated to a NIST traceable standard at the factory.

  • Page 21: Installing The System

    CHAPTER Installing the System Introduction This section describes mounting, alignment and other installation concerns for the LS8500-4. The installation can be broken down into five steps:  Mounting the gauge  Aligning the gauge  Connecting power to the gauge ...
  • Page 22: Mounting Distance

    3.2.1 Mounting Distance When the material is within the depth of field, the gauge makes accurate measurements. Since the best sig- nal comes from the center of the depth of field, the center is the source of the best measurements. This is because the two laser beams totally overlap at the center of the beam crossings and all of the laser power is used to form fringes.
  • Page 23 If a fan is not adequate or practical, an “air purge” can be in- stalled to clear the beam path. Contact your NDC Technologies representative for more details. When mount- ing the gauge, be aware of the environment in which the gauge is operating. Steam, mist, coolant on the ma- terial, ambient temperature, scale and slag may all affect the performance of the gauge.
  • Page 24: Mounting Location

    3.2.4 Mounting Location When mounting the gauge over the material, be sure the gauge is not directly over a roller or some other device. If the laser beam from the gauge strikes an object, it may detect a false Material Present. In this case, the gauge will not be able to detect when the actual material is not in the measurement volume.
  • Page 25: Aligning The Gauge

    3.2.5 Aligning the Gauge Once the gauge is mounted at the proper standoff distance, the critical alignment angles need to be checked. To obtain accurate results, the LS8500-4 must be mounted so the surface being measured is perpendicular to the optical axis. The best method to ensure this is to place a level alongside the gauge. The material being measured should be parallel to the front face of the gauge and the material motion should be parallel to the base of the gauge.
  • Page 26 Under normal conditions, the gauge should be mounted perpendicular (angles A,B=90°±1°) to the direction of travel. Correct for any alignment errors in the gauge configuration. For shiny material, the gauge can be mounted up to 5 degrees from perpendicular in the transverse direction to travel (angle C.) Use the smallest angle possible to eliminate direct reflections back into the gauge.
  • Page 27: Gauge Orientation

    3.2.6 Gauge Orientation The LaserSpeed gauge must be mounted such that the material to be measured moves in a direction parallel to the bottom of the LS8500-4, as shown below. LS8500-4 LS8500-4 – can be mounted either from the bottom or the side LS8500-4X LaserSpeed Pro 8500-4 Instruction Handbook: Installing the System...

  • Page 35: Connecting Power To The Gauge

    Connecting Power to the Gauge The gauge requires a 20–28 VDC (nominal 24 VDC) supply to be connected to Pin 24 and/or Pin 25 with the corresponding ground to Pin 12 and/or Pin 13 of the 25-pin D-sub connector. The supply should be able to drive at least 2 Amps.
  • Page 36: Connecting To Outputs

    Connecting to Outputs On the LS8500-4, the outputs of the gauge are contained on the 9-pin D-sub, 25-pin D-sub, M12 D-Coded Profibus, M12 D-Coded Ethernet and the M5 shutter status connectors located on the rear of the gauge. Their pin values are shown in the following tables. Each signal is explained in detail in the Interfacing with the LS8500-4 section.

  • Page 46: Maximizing Performance

    To ensure quality measurements, the laser beams must maintain “contact” with the product. If the product exhibits large movements during operation, it should be stabilized with external roller guides. NDC Technolo- gies offers optional product guides. Contact your local NDC Technologies sales representative or the factory for additional information.
  • Page 47: Standoff Distance

    3.5.2 Standoff Distance The standoff distance is the distance between the front of the gauge and the center of the measurement region. The standoff distance can be verified by us- ing a business card or sheet of white paper. Both beams can be viewed and the area where the beams overlap is the active measurement region.
  • Page 48: Validation Time Limit Selection

    In this case, a 0.083 mm correction would be made. The same type of correction is made when the material leaves the measurement volume. If problems are encountered during any of the installation steps, contact NDC Technologies for assistance. 3-28...

  • Page 54 Differential vs. Single Ended Pulse Outputs The LS8500-4 Pulse Outputs are available as both differential and single-ended outputs. Using a counter with differential inputs will provide the best noise immunity, so NDC Technologies recommends that the out- puts are used in this configuration.
  • Page 55 4.2.1.7 Quadrature Output Phase Relationships The phase relationship of the quadrature outputs is determined by the direction of the measured velocity. If the velocity is a positive number, Phase A rising edge will lead Phase B rising edge, and if the velocity is neg- ative Phase B will lead Phase A rising edge.
  • Page 56 4.2.1.8 Quadrature Outputs at Extremely Low Pulse Frequencies Note: This section only applies to the pulse outputs—the length and speed available over the RS-232 and Ethernet ports are not affected. The LS8500-4 uses a DDS (Direct Digital Pulse Frequency Error vs. Pulse Frequency Synthesis) circuit to generate the quadra- ture outputs.

  • Page 58 4.2.1.9 Pulse Output Delay The pulse output uses a DDS circuit to generate the pulse output. The speed of the product being measured is obtained by measuring the speed of the product up to 20,000 times per second. This measurement rate is higher than any process control device can handle.
  • Page 59 The Graph above shows the delay in the speed measurement caused by the smoothing algorithm. The delay causes the average speed to lag during acceleration and lead on deceleration. The average speed is fed to the pulse generator to generate the pulse output. Therefore, obtaining length by counting the pulses will give a length error according to the following formula: =(Starting Speed –...
  • Page 60 Caution: When using the Advance Tab to custom select the DIP average and User Update Rate, the DIP average CANNOT be set to a value less than the User Update Rate. If the DIP Average is set to a value less than the User Update Rate the Gauge will automatically reset the DIP Average to the User Update Rate val- ue.

  • Page 62 4.2.1.12 Connecting Material Present Switches This section shows how to connect a commonly used Material Present detector. 4.2.1.13 Single Switch Configuration The D10 is a make/break optical switch. When connecting one optical switch, it should be aligned with the LS8500-4's measurement spot. This configuration can be used in order to more precisely detect the edge of the material.
  • Page 63 Optical Switch Mode LS8500-4 Material Present Mode Light Operate External Active Low Dark Operate External Active High When the product enters the measurement area and triggers the switch, the Material Present signal should activate. This causes the LS8500-4 to start counting length at 0.

The input requires a voltage high (5 to 24V) to activate. The input level should be the same as the voltage connected to the User V input (Pin 20) or 5V if there is nothing connected to the User V input.
  • Page 69 4.2.1.19 Laser Interlock (Pin 16) The Laser Interlock input will switch off the laser power when the connection to ground is broken. This is commonly used with external switches for laser safety. When the interlock pin is connected to ground, the laser is operational.
  • Page 70 4.2.1.20 Shutter Control (Pin 17) All Class 3B laser products are required to have a shutter to terminate the laser beams before exiting the product. The LS8500-4 uses a spring-loaded rotary solenoid as a laser shutter. The spring-loaded action en- sures that when power is not applied to the shutter circuit, the shutter remains closed.

    4.5.2 Thermostat Interface In order to extend the ambient temperature range of LaserSpeed gauges, you can provide water or air cool- ing/heating. This is often accomplished by connecting the gauge to a recirculating heater/chiller, but can also be accomplished by using the gauge's thermostat output. LaserSpeed gauges monitor their internal tempera- tures, and can provide an output indicating when cooling/heating is required.

    CHAPTER SSI Communications Synchronous Serial Interface (SSI or Stegmann Interface) is a point to point digital communications interface commonly used in rotary encoders. The architecture is a master (PLC or microcontroller) to slave (encoder) where the master controls the bit-serial output of the slave shift register by generating appropriate clock sig- nals.
  • Page 222: Ssi Timing And Data Transmission

    SSI Timing and Data Transmission The LaserSpeed SSI interface supports basic transmission of a latched output data word, repeated output of a latched output data word, and recovery from interrupted transmission cycles. The SSI interface operates as a state machine within the LaserSpeed FPGA. The state machine enters its LATCHDATA state when the master device holds the clock output high for longer than the LaserSpeed trans- fer timeout .
  • Page 223: Laserspeed Ssi Timing Parameters (Ssi Slave Mode)

    Repeated transmission cycle A transmission cycle (basic or repeated) can be prematurely terminated if the master discontinues sending clock pulses any time during the normal transmission cycle for the transfer timeout period. The LaserSpeed will automatically transition back to the LATCHDATA state anytime the master clock pulses are stopped for longer than the transfer timeout period.

It is recommended that the idle command be issued before starting Profinet IO communication, and during operation if no data- base items need to be read or written.
  • Page 259 10.3.5 PKW Read Long (Command Code 4) This command allows an integer database item to be read. The Profinet IO master specifies the database item identifier within the command qualifier. If the referenced database item is not an integer, then the response code will be set to “wrong type.” The gauge will ignore the contents of the PKW Request Data.
  • Page 260 10.3.9 PKW Load String (Command Code 8) Since only four data bytes are available for communicating information within the PKW header, it is necessary to load a string into a temporary buffer from where it can be read four bytes at a time. The PKW Load String command performs this function.
  • Page 261 The Profinet IO master specifies a string segment number in the command qualifier field. The string segment number starts at 0, then works up incrementally 1, 2, 3, etc. For a string segment N, the gauge then copies the four supplied string bytes (possibly containing a null terminator) from the PKW Request Header into the temporary buffer at index position N*4.
  • Page 262 For a successful enumeration, the gauge sets the PKW response data as follows: Bit: Word Measurement Item Identifier Word Measurement Item Access Flags Measurement Item Type Measurement Item Identifier: identifier to be used with other measurement table services Measurement Item Type: 0=long, 1=float, 255=unknown Measurement Item Access Flags: 0x02=read-only 10.3.14 PKW Read Long Measurement (Command Code 13) This command allows an integer measurement item to be read.

The PKW re- quest/response bytes appear in the first 8 bytes of the Profibus data. The meaning of the PKW header bytes is the same for requests (from the master) and responses (from the gauge). The PKW header is used to get or set gauge settings, calibration information, or specific internal measure- ment data values.

  • Page 313 CHAPTER 50M+ Option Cable Buffer Board 16.1 Introduction The LaserSpeed cable buffer assembly improves the signal integrity of LaserSpeed pulse outputs when the gauge is used with a DB-25 cable that is 50 meters or greater in length. It was designed to buffer the gauge’s scalable signals when the gauge is attached to a high speed counter card in a Programmable Logic Controller.
  • Page 314 16.3 Installation 16.3.1 Signal Pinout The buffer board is designed to be installed on the DIN rail breakout assembly which has the gauge power supply and the breakout connectors for the 25 and 9 pin connectors. The differential scalable outputs from the gauge enter the board on one side (J1), and the buffered output signals exit on the other (J2).
  • Page 315 16.3.2 Installation of the Buffer Board The cable buffer is attached to the DIN rail adjacent to the DB-25 breakout connector, and the gauge outputs are wired to its inputs. The outputs of the buffer assembly are then wired to the high speed counter card in- stalled in the PLC.
