Page 3: Introduction
Rev. 11-2010 1. Introduction The LM-SD is a laser based distance measurement tool used to measure distances from 0.2m to more than 100m with pinpoint accuracy. A given target can be clearly identified with the help of a red laser sighting point. The usable range of the sensor is dependent upon target physical properties. -

3. Location and Mounting 3.1 Sensor Location The LM-SD Sensor should be installed so as to give a direct view of the target, unobstructed by dust, steam, hoses or passers-by. The mounting should be vibration free, as any motion of the sensor is magnified many times at the laser spot. This is a Class II laser, it should mounted not to shine directly into the eyes of plant personnel. - Page 6 Logika Technologies Inc. Model LM-SD Operator’s Manual Rev. 11-2010 Figure 3.1 shows the zero point on the LM-SD for calibration purposes. There is a parameter “OF” that allows the Zero Point to be changed to some other meaningful point in space.

Page 7: Sensor Mounting
The sensor is fixed to the support with a single 18 mm bolt through the LM-SD’s base mounting stand. The altitude angle may be changed by slightly loosening the three cap screws in the base with a 4mm Allen key, adjusting to the correct angle and retightening the same three screws. -

4. Utility Connections 4.1 Electrical Connections Electrical Overview- All electrical connections (power and signal) to the LM-SD are made via a 15-pin Harting style connector with ground. The sensor is supplied with a mating connector at the back of its enclosure and a standard 2-meter cable with the quick-connect assembly mating to the sensor and bare wire terminals for the junction box connections. - Page 9 Logika Technologies Inc. Model LM-SD Operator’s Manual Rev. 11-2010 Figure 4.1 Connections to LM-SD Harting Connector Cable Specification- Multi-lead cables of 10 x 20 gauge (10 x 0.6 mm²) shielded Teflon insulation for high temperature applications. Outer metallic braid for mechanical protection.
- Page 10 Logika Technologies Inc. Model LM-SD Operator’s Manual Rev. 11-2010 Each lead is color-coded. Junction Box Wiring- Please see Figure 4.1 for the sensor wiring diagram. The supplied cable should be connected directly to the terminals of a junction box. All cables must be shielded all the way to the console with the shield connected to ground to eliminate electrical noise, which may trigger false detection.

Logika Technologies Inc. Model LM-SD Operator’s Manual Rev. 11-2010 4.2 Plumbing Connection Description- Water cooling is required when the ambient temperature at the sensor’s location is higher than 50 C (120 F). Temperatures above this level require protection for the electronics. - Page 12 Logika Technologies Inc. Model LM-SD Operator’s Manual Rev. 11-2010 Compressed Air Requirements Must be clean, dry air free of contaminants. Poor purge air quality will lead to dirty glass which may decrease sensor performance and increase sensor maintenance. Air filtration prior to the sensor purge inlet fitting is recommended for purge air of questionable quality.
