Binary information from ID-DCU MARINE to ID-RPU
3.2.1 ID-RPU functions
ID-RPU (InteliDrive Redundant Protection Unit) is designed for marine applications. This no microprocessor
unit provides redundant engine protection, RPM measuring and back-up power supply switching for the control
system.
ID-RPU monitors InteliDrive central unit and in the case of fail switches itself to the backup mode or Emergency
backup mode and protects the engine using its own binary EMERGENCY STOP and SHUT DOWN inputs and
FUEL and STOP SOLENOID outputs.
The ID-RPU unit has three operational modes:
Normal
ID-DCU MARINE is working and periodically sends the watchdog impulses to the ID-RPU. All ID-RPU
inputs and outputs are processed via ID-DCU MARINE.
Backup
ID-RPU unit doesn’t receive watchdog impulses from the ID-DCU MARINE. The Shut down (Sd1 to
Sd5), Emergency stop inputs (fix 0,5 sec delay) and Overspeed protection are processed via RPU only.
ID-RPU stays in the mode that was before ID-DCU MARINE fail.
Emergency backup
ID-DCU MARINE was in EME mode (or Sd override function was active) before fail. The only
Emergency stop and Overspeed protection is active in this mode. Shut down Sd1 to Sd5 inputs are
inactive. ID-RPU starts to Emergency backup mode after power on without active ID-DCU MARINE.
