3.1.3 Operational modes
LOC (Local) mode
LOC (Local) mode can be set in any mode mentioned above – AUX, EME, HRB, PRP. ID-DCU MARINE
receives only commands entered from the ID-DCU MARINE front panel in LOC (Local) mode. All external
interfaces – binary inputs Remote Start, Blackout Start, RemRepStart, Remote Stop, Rem Start/Stop and
serial line commands are disabled.
LOC (Local) mode is activated and deactivated using ID-DCU MARINE front panel buttons: Enter + Mode→ to
activate, Enter + ←Mode to deactivate. Active LOC (Local) mode is indicated in the upper right corner of the ID-
DCU MARINE display.
OFF mode
All ID-DCU MARINE controller and ID-RPU binary outputs are switched off. Engine can’t be started or running
engine is stopped, prelubrication function is not active. Firmware and controller configuration can be changed in
OFF mode only. OFF mode is available in all applications – AUX, EME, CMB and PRP.
Auxiliary mode (AUX archive)
AUX mode is designed for auxiliary engines.
Controller starts and stops the engine according to the binary inputs Blackout Start or Remote Start, Rem
Start/Stop, Remote Stop or to the ID-DCU MARINE Start / Stop buttons. Binary inputs Blackout Start
and Remote Start and Remote Stop are inactive in LOC (Local) mode.
All engine protections and all configured shutdown protections are active. Controller continuously monitors
all available engine parameters (oil pressure, water temperature, RPM, fuel level etc.). The engine will stop
and activates Common Warning and Common Shutdown outputs and writes record to the history file
when detects any active Shut down alarm. This condition can be signaled by Active call feature to remote
operator via modem, SMS or e-mail.
Emergency mode (EME archive)
The engine is used for emergency engines.
Controller starts and stops the engine according to the binary inputs Blackout Start or Remote Start, Rem
Start/Stop, Remote Stop or to the ID-DCU MARINE Start / Stop buttons. Binary inputs Blackout Start
and Remote Start and Remote Stop are inactive in LOC (Local) mode.
The controller still measures all engine parameters. But it only records to the history file and can notify
remote operator via Active call when detects any parameter out of range.
The only active shut down protection is engine overspeed and Emergency stop.
