4.2 Control Air Supply Unit
1) At connection A2, use the shut−off cock 36HC to open a 30 bar supply to the
control air supply.
2) Make sure that the shut-off cock 36HA is open.
3) Use the valve 19HA to adjust the air pressure for the air spring air to 6 bar. Do a
check of the pressure gages PI4341M and PI4412M.
4) At connection A1, use the shut-off cock 36HB to open an 8 bar supply from the
board supply to the control air supply unit.
5) Use the valve 23HA to adjust the air spring air and control air pressure to 6.5 bar.
Do a check of the pressure gages PI4341M and PI4412M.
6) Make sure that air flows to the blocking valve 2.13.
4.3 WECS-9520 Control System Start
1) Switch on all breakers in the power supply box E85.
2) Check that both green indication LEDs light up on all FCM−20.
Note: The FCM−20 are in operation when the SW LED is constantly green.
4.4 Safety and Alarm System
1) Make sure that the WECS−9520, RCS, safety system, alarm and monitoring
system are set to on.
2) On the control room console, push the EMERGENCY STOP button. Make sure
that the fuel pressure control valve 3.06 and the fuel shut-down pilot valve 3.08
operate.
3) Do the procedure above from the local control and the bridge.
4) Connect the pressure calibration hand-pump to the the pipe that has the pressure
sensor PS1101S.
5) Use the pressure calibration hand-pump to increase the pressure to more than
the reference pressure given in the table below (e.g. to 10 bar).
Table 2: Pressure Calibration
Medium Code No. Pressure Action Time delay
Cylinder cooling water PS1101S 2.5 bar Stop 60 sec
Main bearing oil PS2002S 3.3 bar Stop 10 sec
Piston cooling oil PS2541−xxS 0.4 bar Stop 15 sec
Air spring PS4341S 4.5 bar Stop 0 sec
Note: The setpoints shown above are for reference only. For the applicable
settings, see the Operating Data Sheet 0250−2.
6) Make sure that the pressure switch opens.
7) Decrease the pressure in the pipe to set the pressure switch to the correct
pressure (e.g. 1.5 bar). Make sure that the pressure switch stays open.
8) Disconnect the pressure calibration hand-pump from the pipe.
9) Do the steps above for the pressure switches PS2002S, PS2541−xxS and
PS4341S.
