EG300 Auto Changeover Switch for petrol and gasProduct Technical Parameter:Used for changing the fuel, worked the same as the one in the cockpit.Every time engine starts on gasoline, switching procedure on Lpg depends on reducer temperature.-starting cold engine(first) switching is done after reducer warms up till fixed temperature and fixed engine revolution is crossed.-starting hot engine(reducer temperature is higher than configurationally fixed)switching after fixed time since engine starting and after fixed engine revolution is exceeded.If there's no revolution threshold, (configuration "0" value) automatically switches after fixed time (Lap "Config."/ "Switch").Pressing the switch at the running engine, causes another switching gas/gasonline, gasonline/gas, it's not necessary to exceed revolution threshold.When the unit works, it's signalized by LED on the switch:- Gasonline- all LED turned off- Automaton, reducer temperature too low- all LED pulsing- Automaton ready to switch, still working on gasonline, waiting for revolutions- all LED pulses fast- Work on gas, LED turns on permanently, it qty depends on gas level inside the tank.- Work on gas, reserve: last LED pulses really slow.In case of failure turning (for example when pressure is low) the buzzer turns on.
