3.10.4 HSC hydraulic system alarm
In the drain hydraulic line "T" (Figure 3.10.1), sensor 6 of emergency oil pressure in
the HSC hydraulic system is installed at the outlet of the dosing pump. When the oil pressure
in the drain hydraulic line drops below 0.08 MPa (due to the lack of oil flow because of
insufficient oil level in the oil tank, failure of the feed pump or breakage of hoses), the sensor
is triggered, and a pilot lamp of emergency oil pressure in the HSC hydraulic system (red)
lights up in the pilot lamps unit.
ATTENTION: WHEN THE PILOT LAMP IS ON, IMMEDIATELY STOP THE ENGINE
AND ELIMINATE THE CAUSE THAT LOWERS OIL PRESSURE TO AVOID AN ACCI-
DENT OR FAILURE OF THE HYDRAULIC SYSTEM PARTS.
