4. Servo Oil Supply
Servo oil from the servo oil rail (7, Fig. 3) flows through the exhaust valve control
unit (8) to the servo oil inlet pipe (6). Servo oil then flows through the servo oil supply
pipe (2) and the servo oil inlet (3) into the cylinder lubricating pumps (5). The servo oil
operates the cylinder lubricating pumps (5). For more data see paragraph 5.
The servo oil flows from the cylinder lubricating pumps (5) through the servo oil
outlet (4) into the servo oil return pipe and back to the plant.
The pressure transmitter PT2041A (1) monitors the pressure in the servo oil supply
pipe (2). If there is no servo oil supply pressure or the supply pressure is less than
40 bar, the pressure transmitter PT2041A (1) sends an alarm signal to the ECS. For
the values, see 0250−2 Operating Data Sheet.
