TheUnitdrivestothestartermotoraccordingto
valuesdeterminedinP06andP16.But,startingtheengineisnotpossibleinthisvalues
theunitgivesaStartFailure.InthiscasetheLEDflashesandthehornissounded. The
unitmustberesetbypressingtheRESET (13)buttonbeforeafreshattemptcanbe
made.
FailurewillbeactivewhentheHigh
TemperatureSwitchiswhichisconnectedtotheUnitviaPin8gettingexcessivehotas
resultofpossibleheatingofengine.InthiscasetheLEDflashesandtheHornissounded
andengineshuts-downwithoutanycool-downperiod.
Thesensorthatisconnectedtothe
UnitviaPin7isNormallyClosed. ThecontactwillopenwhenOilPressureintheengine
reachestoproperlevel.Ifthecontactwillnotopentheengineisrunninganditcontinues
