POWER1 and POWER2
Two independent power supplies 8 .. 36 VDC
4.16.2 Features
Dual Power supply
The unit can be supplied from two independent power supplies which ensures RPUs functionality in case of
one of the power supplies’ failure.
Note:
Both power supplies have to be in range of 8 .. 36 VDC. Maximal current for 8 VDC is 0,1 A.
Self diagnostic
The RPU unit self diagnostic feature based on Watch Dog to indicate failure or missing power of the RPU.
Indication of RPU failure is done by:
Binary output RPU which can be connected to binary input of InteliDrive Marine unit and used for further
signalisation
If the RPU unit is operational the output is active
In case of RPU failure the RPU output is not active
Status LED - RPU
Lightening green when the RPU is operational
Lightening RED if InteliDrive Marine unit has failed and the control signals are operated by RPU
NO LED is lightening if the RPU has no power
InteliDrive Marine unit failure detection
Ctrl Heart Beat Binary Output from InteliDrive Marine is connected to binary input WD of Inteli RPU.
Required CtrlHeartBeat rate is 100ms : 100ms
If the signal connected to WD is pulsing, the InteliDrive Marine unit is considered as operational. In this case
the RPU is not taking control, only bypassing the binary signals Fuel Solenoid and Stop Solenoid to the
Engine.
If the signal connected to WD input is NOT pulsing, the InteliDrive Marine unit is considered as NOT
operational and the RPU takes over control over the engine.
RPU engine control while failure of InteliDrive Marine unit
At the moment the RPU takes control over engine it keeps the outputs Fuel Solenoid and Stop Solenoid at
their original levels before the time of failure of InteliDrive Marine unit.
