InteliDrive DCU Marine - 3.0.0 Global Guide
35
Backup mode: the output is activated in case of any shutdown and released 10s after zero RPM reached.
Binary output FUEL SOL
Fuel solenoid output (high side switch) with broken wire (BW) detection active on opened output.
Normal mode: the output is controlled from the ID-DCU MARINE. The logical output Fuel solenoid must be
configured to this output in the configuration of ID-DCU MARINE. If fuel solenoid is not connected to the output,
set Source of the output as Not Used to avoid activation of broken wire protection..
Backup mode: If no shutdown protection active, the output is closed.
SEC RPM IN, SEC RPM GND
Terminals for the secondary RPM pickup. It is possible to connect two redundancy pickups or one pickup to ID-
DCU MARINE and to the ID-RPU in parallel. The ID-RPU will detect overspeed failure on running engine.
Battery voltage measuring
ID-RPU senses battery voltage on both power supply inputs. Those values are connected to the ID-DCU
MARINE trough the CANOvN connector. There is one common Battery V>, V< and delay limit for all three
batteries.
Watchdog
ID-DCU MARINE periodically (~ 0.2s) sends an impulse to the ID-RPU. ID-RPU backup mode is activated
after 1s without watchdog pulse.
Required CtrlHeartBeat rate is 100ms : 100ms
Overspeed protection
The ID-RPU overspeed protection is active in the case of ID-DCU MARINE fail only (backup mode).
Overspeed limit can be set by DIP switch (accessible after cover removal).
ID-RPU Emergency / Auxiliary mode operation
ID-RPU only reflects ID-DCU MARINE setting following way. ID-DCU MARINE controller modes are selected
on ID-DCU MARINE only.
ID-RPU binary inputs Emergency mode Auxiliary mode
Emergency stop Active Active
Shutdown Sd1 - Sd5 Inactive Active
ID-RPU is switched to Emergency mode after power-on reset without ID-DCU MARINE.
ID-RPU operation in the case of ID-DCU MARINE fault
The ID-RPU itself can never start the engine because of the engine starter is controlled from ID-DCU MARINE.
ID-RPU will leave all own binary outputs in the last state when ID-DCU MARINE fail is detected (engine stays
running after ID-DCU MARINE fail). ID-RPU activates corresponding binary outputs when Emergency stop,
Engine overspeed protection or some Shutdown input (not in EME mode or Sd override), is activated.
3.2.2 ID-RPU overspeed setting
ID-RPU Overspeed limit is set via two DIP switches: Prefix and Speed preset.
