Input group Caption Description
INPUTS
RPM Secondary RPM input
ES Emergency stop input, normally closed
CONTROLLER
FR
Fault Reset input from Controller, or external button. This input is used to
switches control back to InteliDrive Marine unit after its failure is fixed.
WD
Isolated input for Watch dog signal, an alive indicator from InteliDrive
Marine unit to I-RPU.
The InteliDrive Marine unit’s binary output is configured as CtrlHeartBeat
and I-RPU uses it its alternation as alive indicator.
RPU
Alive indication from I-RPU. Output is set to 1 if I-RPU is alive, 0 if in faulty
state or power off
InteliDrive Marine unit's binary input 7 has Warning protection in default
configuration to indicate the RPU failure.
CU
FS
Fuel solenoid input from InteliDrive Marine unit. If the InteliDrive Marine is
operational the signal is bypassed through I-RPU.
SS
Stop solenoid input from InteliDrive Marine unit. If the InteliDrive Marine is
operational the signal is bypassed through I-RPU.
ENG
FS
Fuel solenoid output to ENG. Low side switch (controller switches output to
negative power supply terminal).
If InteliDrive Marine is operational the signal is bypassed through I-RPU.
If InteliDrive Marine is not operational, the RPU is controlling the output.
SS
Stop solenoid input from CU. Low side switch (controller switchesoutput to
negative power supply terminal).
If InteliDrive Marine is operational the signal is bypassed through I-RPU.
If InteliDrive Marine is not operational, the RPU is controlling the output.

STATUS LED indicators
LED indicators
LEDs are used for indication of InteliDrive Marine unit functionality
Group LED colour Description
CU
Green LED
Blinking when the InteliDrive Marine is operational and the signals are
bypassed from InteliDrive Marine through RPU to engine
Red LED
Lightening if InteliDrive Marine has failed and the control signals are
operated by RPU
No LED lightening if the RPU unit is not operational or connected to power supply
