1. MineralScan Lite Installation Guidelines Digital Control Lab, LLC. 4647 NW 6 th Street, Suite F Gainesville, FL 32609 Main Unit power 90 – 240 VAC 50/60 Hz (3) 4-20 mA cables (1000m/3000ft max) Ball Mill RF link (10 m) (2) sensors to main unit cable (10 m and 30m) transmitter, sensor, and battery inlet sensor outlet sensor Phone: +1 (352) 692-0800 Fax: +1 (813) 649-8390

2. MineralScan Lite– System Components The Main Unit should be installed near the mill, so the supplied 10 and 30 meter (30 and 90 ft.) cables coils will reach both the Inlet/Outlet bearing sensors from the Main Base Unit. Fixed Inlet/Outlet Bearings Vibration Sensors Mill Shell Wireless Sensor Main Unit

3. Fixed sensors are shipped with a short 30 cm (~1 ft.) cable and a IP67 waterproof connector at the end. DCL supplies 10 meter and 30 meter (30 ft. and 90 ft.) shielded cable coils that each have a connector at one end of the cable and are open in the other end. These cables are passed (run) through conduit pipes from the sensors to the Main Unit. MineralScan Lite– Fixed Sensors Connection

4. MineralScan Lite– Typical Fixed Sensors Installation Fixed Sensors are magnetically attached to both the inlet and outlet bearings covers. Run the supplied cables in conduits to the Main Unit, pull the cables inside of the Main Unit, leave the terminals open, DCL will make the connections during commissioning time.
