Monitoring Systems and Instrumentation
Engine monitoring and instrumentation can be
enhanced by Man Diesel’s PMI system for meas
uring cylinder pressure and by the CoCoSEDS
(Computer Controlled Surveillance – Engine Di
agnostics System) for engine performance evalu
ation. 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 meas
ures to be taken. This ensures that the engine
performance is kept within the prescribed limits
throughout the engines lifetime.
In its basic design the MC engine instrumentation
consists of:
• Engine Control System
• Shutdown sensors, option: 4 75 24
The optional extras are:
• CoCoS system
type EDS online, option: 4 09 660
• PMI system type PT/S offline, option: 4 75 208
• PMI system type online, option: 4 75 25
As most engines are sold for Unattended Machin
ery Spaces (UMS), the following option is normally
included:
• Sensors for alarm, slow down and remote indi
cation according to the classication 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 listed in Section 8.03.
All instruments are identied by a combination of
symbols and a position number as shown in Sec
tion 8.07.
