Location of ECS Electronic Components
1. General
Most of the electronic components necessary for the engine control system (ECS) are
installed on the engine.
The power supply box E85 (not shown) is installed near the engine.
2. Control boxes
Data about the most important control boxes and power supply boxes are given as
follows:
2.1 E85
The E85 has the two 230 VAC power supplies for the CCM-20, MCM-11 and the
LDU-20. The power supply box E85 also has circuit breakers to isolate the MCM-11
and each CCM-20.
2.2 E90
The E90 control box (10) is attached to the fuel side of the rail unit (1) (see Fig. 1).
The control box E90 (shipyard interface box) contains the terminals that give
communication to the external systems.
2.3 E25
The E25 local control box (4) is attached to the free end of the engine. The E25 has
the local control panel, the LDU-20 and the main control module (MCM-11).
2.4 E95.01 to E95.0#
The control boxes E95.01 to E95.0# are attached to the related cylinders on the fuel
side of the rail unit. Each control box has a CCM-20.
Note: The power supplies have redundancy. If it is necessary to isolate the
ECS, make sure that each of the two power supplies are set to off (see
also 4002-1 Engine Control System, paragraph 2.1).
