? W?rtsil? Land Sea Academy Page * Chapter 40 * The opening and closing of the starting pilot valves 2.07 is controlled by the corresponding FCM, depending on the crank angle. The nominal opening angle is 0°, closing angle is 110°. For engines with a large cylinder number the closing angle can be reduced in order to save starting air. The automatic starting valve 2.03 is activated by solenoids ZV70113C and ZV7014C via FCM-20 #1 and FCM-20 #2, if the remote control sends a START signal over the bus. For slow turning and slow turning failure reset the remote control sends separate signals to FCM-20 #1 and FCM-20 #2. The slow turning speed can be adjusted in the WECS-9520 parameters by adopting pulse cycles. Additionally an Air Run signal enables to blow the engine with start air.

W?rtsil? Land Sea Academy Page * Chapter 40 * The WECS-9520 system is built with a single multifunctional electronic module FCM-20 = Flex Control Module 20. One FCM-20 is mounted per cylinder in a cabinet (E95) below the rail unit. An additional online spare module FCM-20 is located in
