!
Recently,!there!were!two!IPS!Joystick!and!DPS!malfunction!incidents!on!40z's:!!ZING!#25!here!in!Newport!and!on!BATEAU!
RELAXEAU!#30!in!Maine.!Here!are!the!lessons!you!can!learn.!
!
1)))KEYLESS)IGNITION)SHUTDOWN)SEQUENCE !
I!am!guilty!of!this,!because!it!seems!one!saves!a!step!by!pushing!the!Engine!
STOP!button!to!shutdown!the!engines!and!then!going!below!to!push!Engine!
Battery!switches!OFF.!!!!!WRONG!!!
!!
To!STOP!the!engines,!press!START/STOP!buttons.!Then!press!the!“IGNITION”!
button!to!turn!the!panel!OFF!causing!its!light!to!go!out!.!!!The!engine!control!
system!needs!to!be!SHUT!DOWN!before!the!power!source!is!removed!by!
turning!off!the!battery!switches.!!This!will!shut!down!the!system!properly,!
and!should!prevent!confusing!the!software!of!the!Joystick!or!Dynamic!
Positioning!System!(DPS).!!
!!
2))))REBOOT! !!!!
This!can!solve!any!number!of!mysterious!engine!control!issues.!Electronic!engine!controls!are!not!much!different!than!your!
computer,!iPhone!or!other!electronic!devices.!!90%!of!the!problems!are!probably!caused!by!an!unusual!switching!sequence!
(e.g.!
random,(unanticipated(operator(button(pushing
)!and!can!be!rectified!by!a!"reboot".!!After!pushing!STOP!to!shutdown!
the!engines:!!Turn!the!Engine!Ignition!Panel!Switches!OFF.!!Then,!go!below!to!turn!the!Engine!Battery!switches!OFF.!!!Be!
sure!the!!Engine!Emergency!Parallel!(EEP)!battery!combiner!switch!is!OFF.!!Also,!turn!the!house!battery!switch!OFF.!!In!other!
words,!shut!down!the!entire!boat.!
!
Wait!at!least!10!seconds!for!the!system!to!sort!itself!out!(
My(printer(and(router(called(for(25(seconds ).!!Then!turn!House!and!
Engine!Battery!switches!ON…!but!not!the!EPP!Parallel.!!!Go!on!deck.!Turn!Ignition!switches!ON!next!to!the!helm.!WAIT!until!
the!engine!display!is!showing!data!numbers!and!has!gone!through!it's!initial!warm!up.!Then!START!the!engines!and!check!
the!Joystick!Control!functions!(IPS!&!DPS).!
!
3)))USE))BATTERY)COMBINERS)TO)OVERCOME)LOW)VOLTAGE !
Upon!turning!ON!the!engine!ignition!switches!next!to!the!helm.!Check!the!
voltage!on!each!engine.!!In!the!case!of!#30,!!the!Port!Engine!had!only!10!
volts!!instead!of!12.5!volts.!!This!creates!alarms,!particularly!when!trying!to!
start!it,!because!Volvo!Penta!electronics!don't!function!below!10!Volts.!!The!
starter,!when!activated,!draws!lots!of!current!and!will!pull!down!the!voltage!
even!lower!and!won't!start.!
!
You!might!think!that!it's!a!simple!matter!of!turning!on!the!EEP!switch!(that!
combines!the!two!engine!batteries)!between!the!Engine!Battery!
switches.!!And,!it!would!be!if!there!were!only!a!small!voltage!differential!
reading!on!the!engine!displays.!But!in!this!case,!with!the!port!engine!battery!as!low!as!10!volts,!combing!them!gets!to!a!an!
inadequate!11!volts.!!!
!
Fear!not!!!There!are!3!!other!ways!to!get!going!again!in!the!above!extreme!case.!!In!each!method!below,!start!with!House!
and!Engine!battery!switches!OFF!and!the!EEP!Switch!OFF.!Then!after!turning!the!House!Battery!Switch!ON:!
!
A.!!!Boost!the!port!engine!battery!with!the!starboard!engine!alternator!&!battery.!!!!
Turn!the!Starboard!Engine!battery!switch!ON!(Not!the!Port!Engine!or!EEP!switch).!Up!on!deck,!turn!the!Starboard!Engine!
ignition!switch!ON.!!Wait!until!the!engine!display!shows!data.!Then!START!the!Starboard!Engine.!With!that!alternator!now!
charging!batteries!as!evidenced!by!voltage!climbing,!go!belowdecks!and!first!push!the!EEP!switch!ON.!Then!turn!the!Port!
Engine!Battery!Switch!ON.!!Then!up!on!deck,!turn!the!Port!Engine!Ignition!Switch!ON.!Check!to!see!that!the!voltage!on!each!
engine!display!is!reading!above!12!volts!and!climbing.!!If!so,!START!the!Port!Engine.!!!
!
B.!!Charge!with!the!Genset!
Turn!the!Genset!ON!and!be!sure!it's!showing!a!charge!by!rising!voltage!over!the!House!DC!Panel.!!!Turn!the!EEP!switch!ON.!
Turn!both!Engine!Battery!switches!ON.!!Turn!Engine!Ignition!switches!ON.!!Insure!good!voltage!readings!on!the!Engine!Data!
Displays.!!Start!engines.!!With!the!engines!now!charging!through!alternators,!you!can!shutdown!the!Generator.!!!!!
