For the limits of the alarm, slow-down and shutdown signals (see 0250−2).
Pressure measured approximately 6.5 m above crankshaft center line.
(1)
At 100% engine load.
(2)
At stand-by condition; during commissioning of the fuel system, the fuel pressure at
the inlet of the fuel pumps is adjusted to 10 bar.
(3)
The water flow must be in the specified limits (scavenge air cooler specification).
(4)
Maximum temperature difference between the cylinders.
(4)
The value can be different. For the applicable setting value, refer to the
specification of the damper manufacturer.
