MOP Operation screen

ME-B - System for C/RThis is MOPs screen.

MOPs screen had a security system for a chief engineer.

In order to adjusts cylinder oil feed rate and fuel oil

injection rate, and P-max,The chief engineers need to put password into the screen.

MOP Operation screen


This MOP operation screen displays the condition of engine.

It is possible to check HPS running, pressure, engine speed, scavenging pressure, fuel index,

and other functions in this screen.

Operation

Basically, there is no possibility to adjust except for the 1 cylinder cut running.

1.Select the cylinder.2.Slowly reduce the Chief limiter.(Adjust and Apply)

3. The finally value to 0.
