7. ERAL DESCRIPTION 1 0 Installing and Turning on the BBC for the First Time Installing the BBC will only take you a few minutes the various components being wired and tested before delivery The following simple operations should be performed a Choose a mounting location for the BBC Make sure the place you choose is not subject to excessive mechanical and electrical stress Direct exposure of the various elements making upthe system to atmospheric agents should also be avoided whenever this is possible b Mechanically fasten the temperature probes to the special locations indicated by the engine manufacturers Position the pitot tube the dynamic intake the static intake and the connection tubes Be extremely cautions not to throttle the tubes or let foreign matters into the anemometer components d Connect the unit to a 12 Vdc battery using the supplied fuse then plug in the patch cord the BBC240EU or BBC240EUD and the probes as is shown in the wiring diagram Table 3 e Make sure that instrument settings are in accordance with the aircraft characteristics using the SETUP function in the DIAGNOSTICS menu see 3 8 f Before starting to fly make sure that the instruments are working correctly both when the engine is running and when it is stopped 1 1 Power on Turn on with the special switch Your BBC will execute a self check lasting about two seconds and will then be ready for flight The selected instruments are displayed
