Page 14: Installation
Ensure that the LSP Head is mounted securely, in a location where the effects of vibration, dust and fumes are kept to a minimum. Ensure that the scanning sight path is not obscured. The LSP 10, 20 & 21 have a focus distance factory set at 2000 mm / 79 in. Refer to Section 2.2 for details of how to change the focus distance. Choose a mounting location which minimises external heating of the scanner. If the ambient temperature of the unit exceeds the specified maximum, a cooling system (available from AMETEK Land) must be fitted. If the instrument is to be used in environments where gases resulting from combustion are present, contact AMETEK Land so that the application can be fully assessed before you install the scanner.

The focus distance can be user-adjusted in the range 1m / 40in to infinity. Remove the front cover of the scanner (the panel nearest the laser switch). Refer to Fig. 2. The focus can be adjusted by turning the Focusing ring, which is held in place by the Clamping plate. Remove the top screw from the Clamping plate to free the Focusing ring. In order to focus the instrument accurately, the focusing mechanism must first be 'zeroed'. -
Page 16: Positioning The Scanner
Linescanner Head User Guide 2.3 Positioning The Scanner Before installing the scanner, refer to the cautions given in Section 2.1. The scanner must be installed so that the target plane is parallel to the scanner window. Refer to Fig. 3 (below). The width of the scan (SW) is proportional to the distance (TD) between the scanner and the target plane. Choose a target distance that will give a scan line that just exceeds the width of the product, as this gives maximum spatial resolution. TP = TD cos 40 40°... -
Page 17: Scan Widths And Target Size
User Guide Linescanner Head 2.4 Scan Widths and Target Size 2.4.1 Scan Width The full scan angle for the LSP Scanner is 80°, and the Scan Width (SW) can be calculated as: SW = (TD + 35) x 1.678 mm SW = (TD +1.38) x 1.678 inches Where ‘TD’ is the perpendicular Target Distance between the LSP window and the target plane. At the scan angle extremes (± 40°) the length of the Target Path (TP) between the scanner and the target is: TP = (TD + 35) / 0.766 mm TP = (TD +1.38) / 0.766 inches Note The active scan angle may be set in the range 40 to 80°. See the Landscan Configuration or WCA software guides for further information. 2.4.2 Target Size The calculated Target Size is strictly only circular at a scan angle of zero degrees, i.e. perpendicular to the instrument. At all other scan angles, the target spot will be an ellipse. The elliptical target size is shown in the following tables for the scan angle extremes (± 40°). - Page 18 Linescanner Head User Guide Page 12...

Page 20: Alignment And Scan Direction
Linescanner Head User Guide 2.5 Alignment and Scan Direction Each AMETEK Land LSP Head has an integral laser unit that can be used to help align the scanner during installation. For instructions on how to use the laser alignment unit, refer to Section 4.0 of this User Guide. To interpret the scan profile produced by the scanner, the scan direction of the unit must be known. The scan direction is indicated by an embossed arrowhead cast into the top of the scanner casing (See Fig. 4 overleaf). The design of the scanner mountings ensures that the scanner will always be replaced in the correct orientation, should the scanner be removed from the application for servicing etc. -
Page 21: Installation Precautions
2.6.2 Infrared reflections All practical targets have some reflectivity within the infrared waveband. This reflectivity increases as the target emissivity reduces (see Section 5.0). Therefore, the scanner sees some radiant heat energy from reflections of surrounding objects, as well as from the target source. This energy is not usually sufficient to have an effect on the measurement, but take care to ensure that objects of similar or higher temperature to the target are not placed where reflected energy may enter the scanner. 2.6.3 Compensating for losses in viewing windows The emissivity control on the LSP can be set to compensate for target emissivity and window losses (such as when using the LSP Sealed to Process Flange). A simple calculation provides the correct setting, as follows: For example: if viewing a target of emissivity 0.8 through a sapphire window the effective emissivity setting should be the product of the surface emissivity and the transmission of the sapphire. Transmission is 100% minus the reflection loss of each surface (7% + 7%) = 86% . The equivalent emissivity setting to overcome this loss may be calculated as follows: 1 - (losses) / 100 which equals 0.86. This value should then be multiplied by the value of target emissivity. Hence emissivity setting = 0.86 x 0.80 = 0.69 Note Ensure you choose an appropriate window material for the spectral response of the LSP scanner you have. For more information, contact AMETEK Land.

To reset the IP address back to 10.1.10.10x, press the laser button until the light goes out, then immediately release the button. 3.1.3 Start-up time The scanner will begin its start-up when connected to an appropriate power source. The scanner takes approximately 2 minutes to boot, during which time it will not operate. 3.2 Water Requirements (Water-Cooled Units Only) If the LSP Linescanner Head is to be used in an environment where ambient temperatures are above the maximum specified, the AMETEK Land Water Cooled Air Purge mounting accessory must be used. This mounting accessory requires a constant water supply. The special mounting plate has internal water channels with inflow and outflow connections (G1/8 tappings) in the plate edge. There is no preferred flow orientation. However, if the scanner is mounted in a position where one of the water connectors is higher than the other, then the lower connector must be used for the mains water in-flow. The Water Cooled Mounting Plate is supplied fitted with hose connectors suitable for 9.5mm / 3/8in bore water hose. The water flow rate required will depend upon each... -
Page 24: Air Requirements (Air-Purged / Cooled Units Only)
Linescanner Head User Guide 3.3 Air Requirements (Air-Purged / Cooled Units Only) If the LSP Linescanner Head is to be used in an environment where high concentrations of dust are likely to be encountered, the AMETEK Land Air Purge Baseplate mounting accessory must be used. The baseplate incorporates a cross flow purge for the scanner window. The purge is designed to keep the window free from dust particles, it will not clear the instrument sight path. Connect the air supply via the G3/8 threaded hole at the end of the mounting plate. If possible, ensure that the air purge exit direction is downwards. Make sure that air purge exit is not impeded by mounting structures. The air purge flow rate depends upon local conditions of the installation and scanner orientation, but a rate of 300 litres per minute / 12.36 ft³ per minute at an inlet pressure of 1.4psi / 1m WG is typically sufficient. CAUTION To minimise the risk of permanent damage, use a high quality air supply. The air used must be dry and free from oil. Air purge direction Air supply Restriction of purge air... -

Page 26: Using The Laser Alignment Unit
Linescanner Head User Guide 4.1 Using the Laser Alignment Unit The Laser Alignment Unit is a CLASS 2 laser product. Be aware of all CLASS 2 Laser Safety Warnings whenever the Laser Alignment Unit is in use. Press the Laser Alignment button. The button is next to the interface connector on the top of the scanner body. The scan frequency of the instrument reduces to approximately 1Hz and the Laser Alignment button flashes to indicate that the laser is active. A red stripe of laser light is projected through the window of the scanner, indicating the position and extents of the scan line. Adjust the scanner position as required so that the product almost fills the width of the scan defined by the laser. Note When the Laser Alignment Unit is active, the scanner does not measure the target temperature. To switch off the laser, press the flashing Laser Alignment button. When the Laser Alignment unit is switched off, the scanner stabilises for approximately 60 seconds. The scanner will then begin normal operation and temperature information is available. Alternatively, the Laser Alignment facility can be operated remotely from the Landscan Software. Page 20... -
Page 27: Emissivity - Typical Values
User Guide Linescanner Head 5 Emissivity - Typical Values 5.1 Setting the Emissivity value By default, the emissivity value is set remotely via the Landscan Configuration Software or by Landscan WCA software, if this option is used. For further information, see the relevant User Guide. Alternatively, the emissivity setting can be set to a fixed value using the procedure below. Unscrew the four bolts holding the scanner side plates to the body using a 5mm allen/hex key. Notice that the two sides of the scanner are dissimilar and identify the ‘open’ side where the external parts of the optical system can be clearly seen. On the ‘open’ side of the scanner, find the jumper marked JM3 towards the right edge of the PCB (shown inside green circle below). Remove the jumper from the PCB. Page 21... - Page 28 Linescanner Head User Guide Turn the scanner around 180°. You should now be looking at the side with a PCB much closer to the front edge of the casing. Locate the pins marked LK3, again towards the right hand side of the PCB. Note that these pins are located on the exposed part of the second layer of PCB. Replace the jumper removed in step 3 on the TOP TWO of the three pins of LK3 marked ‘Internal Emissivity’. The scanners emissivity can now be set using the tow identical rotary switches that can be seen towards the middle of the PCB. The left switch sets the first decimal place, the right switch sets the second decimal place. For examples, see the table below. Left switch setting Right switch setting Emissivity setting 0.85 0.72 1.00 Page 22...

Page 31: Setting The Scan Frequency
User Guide Linescanner Head Setting the Scan Frequency The majority of scanners are supplied with the scan frequency set to 50 Hz. LSP scanners are set to 20 Hz. However, you can set the scan frequency to suit your application. The scan frequency can be set in the range 10 to 150 Hz, in 1 Hz increments, from the Landscan software. The scan frequency can also be set via a switch in the scanner head. 6.1 Changing the Scan Frequency setting using the internal switch CAUTION Remove the scanner plug before removing the scanner end plate. This ensures that the unit is electrically isolated. -

Page 34: Skew Angle
Linescanner Head User Guide 6.5 Skew Angle When a linescanning thermometer is scanning across a moving product travelling along a line, setting the scan frequency too low may cause the scan line to be excessively tilted, or 'skewed'. When the product speed is high and the scan frequency is low, the skew is more apparent, and results in an inaccurate indication of product width. Product movement Example 1 - A greater skew angle is created when high product Skew angle θ speeds are combined with low scan frequencies. Note: During product width calculations, the apparent width is displayed greater than the actual width. θ Example 2 - When high product speeds are combined with medium scan frequencies, the skew angle is reduced when compared to Example 1. -
Page 35: Internal Ambient Temperature Sensor
User Guide Linescanner Head Internal Ambient Temperature Sensor 7.1 Introduction The Internal Ambient Temperature Sensor (IATS) is designed to monitor and forewarn the operator of possible instrument damage due to overheating. Overheating can be caused by high ambient temperatures, or interrupted and reduced flow of coolant. An 'early warning' level is set to 50°C / 122°F. This gives an indication of possible over- temperature within the instrument. The maximum operating limit for the LSP Linescanner Head is 60°C / 140°F. If the indicated internal temperature exceeds the stated limit, take action immediately to provide additional cooling to the instrument. If additional cooling cannot be provided, the instrument must be removed from the source of the excessive ambient temperature in order to reduce the likelihood of any permanent damage. -
Page 36: Maintenance
The recommended maintenance routine involves periodic checks on unit services and ensuring that the scanner viewing window is kept clean and free from contamination. 8.1 Air Purge Services The air purge system reduces the amount of dust or dirt reaching the viewing window of the scanner. The effectiveness of the purge is dependent upon the air flow rate and the nature of any airborne dirt. Check the cleanliness of the window on a regular basis as part of your local maintenance schedule. If the contamination rate is too high, then it may be necessary to increase the purge flow rate. It is of the utmost importance that the air supply to the purge system is of high quality and is supplied clean and dry, otherwise window contamination may result, and the diffuser within the purge unit may become blocked. If the viewing window becomes dirty, clean it with a soft clean cloth. If stubborn deposits are found, moisten the cleaning cloth with a mild detergent. If the scanner viewing window gets damaged, the unit must be returned to AMETEK Land for a window replacement. 8.2 Water And Air Cooling Services The main problems associated with the water and air cooling systems are inadvertent supply shut-off and over-cooling. Check the flow rate on a regular basis as part of your local maintenance schedule. Use a flow rate monitor and alarm system. Over-cooling causes condensation to form on the unit. To prevent this happening, make sure that the water or air supply temperature is above the local dew-point temperature. 8.3 Plate Mounted Blower Unit Refer to the Plate Mounted Blower Unit User Guide (198.252) for details of maintenance for this unit.
