Read this manual carefully before starting any work!
This is particularly applicable to the chapter “General Safety Instructions”
and the respective safety instructions in the chapters.
6.2 Components of the electronics box
6.2.1 Internal drive lever control unit MPC
Installation location:
The MPC (Marine-Power-Control) is installed in the
E-box and is connected to the connector board via
a separate cable harness.
Function
In addition to the internal cabling, the connection lines to/from the drive lever must be connected directly to
the MPC. To achieve this, the CAN lines are fed through the E-box to the MPC via PG glands.
It is optionally possible to transmit the ship operator’s requests to the control unit externally via the 4-20 mA
signal of an external electric drive lever control unit.
The drive lever control unit sets the speed request specified by the operator for the system or the engine
control unit.
→ The engine control unit uses the speed request and various marginal conditions to calculate the
necessary target injection quantity.
Internal drive lever control unit
The internal drive lever control unit is optionally offered by MAN as an MPC (Marine Power Control) for
non-classified systems. The associated drive lever is required for the MPC.
Drive lever and MPC communicate with each other via CAN.
The MPC transmits the speed request internally to the system via a 4-20 mA signal to the internal interface.
No separate voltage supply is required.
External connecting cables for the internal MPC and cross-communication are to be fed through the cable
gland. All other signals must be wired to X88.
An external drive lever control unit is connected from outside to the E-box via X9 connector. The system
expects a 4-20 mA signal for the speed request at the interface
