Monitoring Systems and Instrumentation
The Engine Control System (ECS) can be sup‑
ported by the computer<strong>is</strong>ed PMI system and
the CoCoS�EDS on�line (Computer Controlled
Surveillance�Engine Diagnostics System), both of
which have been in service since 994.
The monitoring system measures the main para‑
meters of the engine and makes an evaluation of
the general engine condition, indicating the coun‑
termeasures to be taken. <strong>Th<strong>is</strong></strong> ensures that the
engine performance <strong>is</strong> kept within the prescribed
limits throughout the engine’s lifetime.
In its basic design the ME�engine instrumentation
cons<strong>is</strong>ts of:
• Engine Control System
• Shut�down sensors, option: 4 75 24
• PMI system type PT/S off�line, option: 4 75 208
The optional extras are:
• CoCoS system
type EDS on�line, option: 4 09 660
• PMI system, on�line, option: 4 75 2 5
As most engines are sold for Unattended Machin‑
ery Spaces (UMS), the following option <strong>is</strong> normally
included:
• Sensors for alarm, slow down and remote indi‑
cation according to the classification society’s
and MAN Diesel’s requirements for UMS,
option: 4 75 27, see Section 8.04.
Sensors for CoCoS can be ordered, if required, as
option: 4 75 29. They are l<strong>is</strong>ted in Section 8.03.
All instruments are identified by a combination of
symbols and a position number as shown in Sec‑
tion 8.07.
