Manual start:
A. turn the key clockwise until the first position "preheat"; all LEDs light up for test;
B. “Low oil pressure” and “preheat” LEDs light up; “preheat” LED stays lighted for a set time (from 10 to 50 seconds;
set with the rear trimmer);
C. As “engine running” LED starts to flash, turn the key to position "start", hold it till the engine stars and “engine
running” LED is steady lighted. If you do not turn the key within 15 seconds, "alarm" and "elettro stop" activate
and "fuel valve" disactivate.
D. to stop the engine, turn the key counter-clockwise till "off" position, press "stop" button or activate "emergency"
input (#5).
Low fuel level (input #6): "low fuel level" LED flashes and "alarm" outout (#2) is activated. After 5 minutes, if
there is no manual intervention , the device stops the engine and "low fuel level" remains lighted. After
refueling, you must first turn the key back to "off" in order to re-start the engine.
Low oil pressure (input #3): related LED lights up and the device stops the engine and activates "alarm"
output (#2). After refilling, you must first turn the key back to "off" in order to re-start the engine.
High temperature (input #4): “high temperature” LED lights up, the device stops the engine and activates
"alarm" output (#2). You must first turn the key back to "off" in order to re-start the engine.

Auto start:
A. turn the key clockwise until the first position "preheat"; all LEDs light up for test;
B. “Low oil pressure” and “preheat” LEDs light up; “preheat” LED stays lighted for a set time (from 10 to 50 seconds;
set with the rear trimmer);
C. Press “auto” button: “auto” LED starts flashing; as “remote start” is activated, the device makes 4 startup tries:
1. 4 seconds “start” #12 and “fuel” #9 are activated,
2. 3 seconds the device checks wheter the engine is running (oil pressure ok),
3. if engine is not running, it is stopped. Then starts the next try.
If after 4 tries the engine is still not running, the "alarm" output #2 and "electric stop" #10 are activated,
and "fuel" is deactivated.
E. to stop the engine, turn the key counter-clockwise till "off" position, press "stop" button or activate "emergency"
input (#5).
If “remote start” input #7 is deactivated, the device stops the engine by activating "electric stop" output
#10 and by deactivating "fuel" output #9; it then waits that “remote start” (#7) is reactivated: at this point it
repeats the auto start procedure.
High temperature (input #4): the device stops the engine by activating "electric stop" output #10 and by
deactivating "fuel" output #9; it then waits that temperature alarm goes off: at this point it repeats the auto start
procedure.
low fuel alarm (input #6): the device waits 5 minutes; then, if there is no manual intervention, It stops the
engine by activating "electric stop" output #10 and by deactivating "fuel" output #9.
Low oil pressure (input #3): the device stops the engine by activating "electric stop" output #10 and by
deactivating "fuel" output #9.
