Description
Output Value of Loadsharing functional block inside ID-DCU Marine controller. It is Loadsharing: RQSP
Ramp value influenced by loadsharing variation signal (this signal can increase / decrease the RQSP Ramp
value by +/- 1,5%). The ThrottlePos value is intended to send as required speed to an engine. Load sharing
block diagram (page 151).
See following chart describing ThrottlePos value in Running and Loadsharing state.
Note: The regulation speed of loadsharing variation signal (max
±
1,5%) is given by PI loop parameters
Loadsharing: Load Gain and Load Int. The Loadsharing: ThrottlePos value is influenced by ramping
specified by Loadsharing: RQSP Ramp setpoint.
Note: The Loadsharing state can be activated from Running state and if both following conditions are
met:
Actual Engine speed is in range specified by setpoints Loadsharing: ClutchMinSpeed and
ClutchMaxSpeed
Logical Binary input Rem Clutch is active (or I/0 front panel button is pressed)
There is loadsharing activation delay specified by setpoint Loadsharing: Clutch Del to postpone
loadsharing regulation after transient events after engine mechanical connection to gear-box.
Note: It is essential requirement to configure engine load information (ECU value “actual load”, physical
analog input reading actuator position feedback or boost pressure etc.) into Logical Analog input Engine
Torque for loadsharing functionality.
Note: All ID-DCU Marine controllers working in the same loadsharing group have to be interconnected
on CAN2 bus, controllers must have different controller addresses.
Note: Loadsharing state - the Loadsharing: Back Up Speed value is taken into account instead of Engine
Values: Speed Request if the Logical Analog input Requested RPM indicates Sensor Fail (#####) and
Logical Binary input Back Up Speed is active.
