Page 4: Overview
Section 1 1 Overview The DynaVision® B800 sensor by LMI Technologies Inc. is designed for use in a lumber profile scanner to supply a 3 dimensional profile for lumber recovery optimization. B800 based scanning systems are primarily designed to provide true shape, 3D measurements of lumber to enable computerized optimization of lumber processing centres such as edgers, trimmers, and sorters. - Page 5 Access to the sensor data is based on standard TCP/IP and UDP Ethernet network protocol allowing the DynaVision® B800 to be interfaced to many hardware and OS platforms. Each B800 sensor provides data for a 2 foot (610 mm) section (the length of each B800 sensor) of the material to be scanned.

Section 2 2 Laser Safety 2.1 General Information The laser light sources used in LMI Sensors are semiconductor lasers emitting visible light. LMI Laser Sensors have a 2/ll, 3R/llla or 3B/lllb classification depending on model. Class 2/ll and 3R/llla sensors are referred to as “products” indicating that they fully comply with the standards relating to laser products specified in IEC 60825-1 and U.S. -

2.2.2 User Precautions & OEM Responsibilities The specific user precautions as specified in IEC 60825-1 and FDA CFR Title 21 Part 1040 are: Requirements Class 2/ll Class 3R/3a Class 3B/3b Laser safety officer Not required Not required Required Remote interlock Not required Not required Required**... - Page 9 A detailed description of the safety items that must be added to the OEM design is listed below: Remote Interlock A remote interlock connection must be present in Class IIIB laser systems. This permits remote switches to be attached in serial with the keylock switch on the controls. The deactivation of any remote switches must prevent power from being supplied to any lasers.

Warning Signs Laser warning signs must be located in the vicinity of the sensor such that they will be readily observed. Examples of laser warning signs are: FDA Example IEC Example 2.3 Requirements on laser systems sold or used in the USA The OEM’s laser system which incorporates laser components or laser products manufactured by LMI Technologies requires certification by the FDA. -
Page 11: Sensor Description
Section 3 3 Sensor Description 3.1 General Each sensor projects 8 laser beams onto a target surface at 3" (76.2 mm) spacing. Each beam produces a laser spot which is detected by one or both integrated CCD line cameras and the respective target range is calculated using the triangulation method. The arrangement of the cameras allows ranges to be calculated for all lasers at the actual scan rate of the CCD without overlapping spots. -

Page 13: Maintenance
Do not pressure wash the sensors as this can cause severe damage. 4.2 Welding and the Scanner Frame DynaVision® sensors are optical apparatus, and care must be taken to ensure that nothing affects their optical performance. The camera used inside each sensor can be damaged by very intense light. -

Page 15: Mounting
5.2 Mounting The sensors are held in place at three points (mounting holes). It’s suggested that the sensors be mounted onto studs attached to the frame rather than bolted directly to the frame itself. This allows the installation of shims to aim the scan head in case the frame is not aligned correctly. -
Page 16: Relative To Other Sensors
5.2.1.2 Relative To Other Sensors For optimum performance sensors should be mounted so their position is offset by a minimum of ½ inch from the sensors immediately adjacent to them. This ensures each sensor’s cameras have a clear field of view of only it’s own lasers. For systems with both Top and Bottom mounted sensors, each Top-Bottom pair of sensors should have the same offset distance. -
Page 17: Chain Spacing
5.2.2 Chain Spacing Any chains that run between B800 sensors (2 foot centers) must have chain guides as narrow as possible. This may be achieved by eliminating the side rails at the point that the laser would strike it and let the chain only travel on the bottom center guide. It is mandatory to keep each sensor’s field-of-view unobstructed and to prevent lasers from hitting the chain. - Page 18 The illustration below shows an example of proper chain spacing. The chains are run between sensors giving both cameras on each sensor a clear view of every laser throughout the sensor’s measurement range. In addition, no lasers are hitting the chain or other metal objects.

Section 6 6 OEM Design 6.1 Design Requirements 6.1.1 System Calibration Once all the sensors have been mounted in the scanner frame, two calibration calculations need to be performed. While the two calculations are described separately below, the recommended procedures for each calculation are the same and may be combined into one calibration sequence. -
Page 22: Design Recommendations
Repeat the process for all the sensors mounted below the transfer chain. For our example we’ll say the average distance, or ‘Bottom Preset’ value is 22”. Pass a calibration profile bar of known thickness through the scanner. For each top mounted sensor, read the spot buffers of each laser and calculate the average range reading for the entire width of the calibration bar. -
