Main Instrument Panel
As standard the engine is equipped with an instrument panel, comprising instruments for visual indication of the most essential pressures.
Illustrated on fig. 1.
The instrument panel is mounted flexibly on rubber elements and all manometer connections are connected to the panel by means of flexible hoses, as shown on fig. 2.

Remarks to individual Parameters
A. Fuel Oil Pressure, HFO-operation
When operating on HFO, the system pressure must be sufficient to depress any tendency to gasification of the hot fuel.
The system pressure has to be adjusted according to the fuel oil preheating temperature.
B. Cooling Water Pressure, Alarm Set Points
As the system pressure in case of pump failure will depend on the height of the expansion tank above the engine, the alarm set point has to be adjusted to 0.4 bar plus the static pressure.
C. Nozzle Cooling Oil System
The nozzle cooling oil system is only applied for stationary engines.
