8. Cylinder Lubricating System − Control
8.1 Control System
The WECS−9520 controls the cylinder lubricating system.
The control system includes a row of ALM-20, one ALM-20 for each cylinder (see
Fig. 8). The CAN Bus transmits the signals. To prevent faults one more CAN Bus is
installed and gives redundancy.
The power supply box E85 and the control box E90 supply the necessary power for
the ALM-20. Each ALM-20 has a pressure transmitter to monitor the metering
pressure.

Fig. 8: Control System
The Flex Control Module(s)−20 (FCM−20) get the necessary data from the last and
next to last cylinders. The SSI Bus transmits the signals from the crank angle sensor
unit. To prevent faults one more SSI Bus is installed and gives redundancy (see
4002−1 Engine Control System WECS-9520).
The 4/2-way solenoid valves operate the lubricating pumps.
