Page 9: Laser Safety
Classes of Lasers The AGV-SPO series scan head can be used with a variety of lasers. Each laser is assigned a particular hazard level, which is indicated by the Laser Class label that is affixed to the device near the location where laser radiation is emitted. -
Page 10: Laser Area
The laser area must be designated by suitable warning signs or lamps and protected by appropriate shading and interlock switches. Figure 1: Laser Area of an AGV-SPO Scan Head www.aerotech.com... -
Page 11: Laser Shutter
Do not stare into the laser beam, put your body parts in the laser area, or expose yourself to reflections from powerful beams. WARNING: Aerotech recommends that you only use a Class 1 HeNe laser to do alignments. If a Class 1 HeNe laser is not available, use the lowest power setting on the available laser and remote beam sensing techniques. - Page 12 Laser Shutter AGV-SPO Hardware Manual This page intentionally left blank. www.aerotech.com...

Page 18: Environmental Specifications
Indoor use only 1.2. Accuracy and Temperature Effects Aerotech products are designed for and built in a 20°C (68°F) environment. Extreme temperature changes could cause a decrease in performance or permanent damage to the AGV-SPO. At a minimum, the environmental temperature must be controlled to within 0.25ºC per 24 hours to ensure the AGV-SPO specifications are repeatable over an extended period of time. -

The alignment tolerance should be based on the variability acceptable in the optical system. Aerotech recommends that you align the bottom surface of the AGV parallel to the work plane within 25 µm as a starting point. - Page 25 6. Insert the appropriate hardware into the holes of the mounting flange. The screw length must be long enough to provide at least 1.0x diameter thread engagement. 7. Using an appropriate wrench, tighten the hardware. Alternate tightening of the screws so that the AGV-SPO scan head comes together evenly on the mounting flange. www.aerotech.com...

Page 28: Air Requirements
If compressed air is used, it must be filtered to 0.25 microns, dry to 0º F dew point, and oil free. The filtration requirement is necessary to prevent particles from damaging the optical surfaces of the turning mirrors. Figure 2-4: Air-Cooling (-AC) Locations www.aerotech.com... -
Page 29: Water Requirements
Aerotech recommends using an appropriately sized chiller capable of delivering 0.35 GPM (gallons per minute) at 60 psid. The coolant must be delivered and retrieved from the scan head via appropriate hoses with outer diameters of 6 mm. - Page 30 2.6.

Page 31: Chapter 3: Electrical Specifications And Installation
Aerotech motion control systems are adjusted at the factory for optimum performance. When the AGV-SPO is part of a complete Aerotech motion control system, setup should only require that you connect the galvo to the appropriate drive chassis with the cables provided. Labels on the system components should indicate the appropriate connections. -
Page 32: Motor And Feedback Connectors
Restrict access to the galvo when it is connected to a power source. If the AGV-SPO is built with standard Aerotech motors and encoders, it will arrive from the factory completely wired and assembled. The AGV scan heads contain galvano motors with dual analog encoder feedback. Both the primary and secondary position feedback signals of each galvano motor must be tuned for optimal performance. -
