Component description b) Electric engine triggering with 4–20 mA signal Alternatively the engine can be triggered with a 4–20 mA current signal from an electrical throttle lever control system (4–20 mA ў idling – full-load). If the 4–20 mA signal fails, the engine will continue to run at idling speed. е Alarm “Electronic – failure” at the BE1 engine monitor (EDC continuous light fault) The EDC speed signal (see also page 99) can be read into the throttle lever control sys- tem and used for engine synchronisation. Plug A supplied for socket X9 (on the terminal box) has internal screw clamps so that the boatyard will not need crimping tools. Plug assignment X9: Pin 9:
Input for 4–20 mA signal (+) Pin 10: Input for 4–20 mA signal (–) Pin 15: Output for speed signal (+) Pin 16: Output for speed signal (–) Speed output + – Kl. 1 Pin 28, EDC controller Terminal 1, terminal box EBE 17 EBE 16 Kl. 15, EDC controller Kl. 14, EDC controller Input for 4–20 mA, + engine + Plug for throttle lever A X9 for electrical engine triggering (4–20 mA) Terminal box The 4–20 mA input (terminals 9+10, EDC control box) is an isolated input. If the speed signal is used it must be ensured that the signal is either processed isolated or that the same negative potential is used as for the EDC control unit. 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
