PROCEDURE
1 Make sure that the remote control system (RCS), the engine safety system (ESS), and
the alarm and monitoring system (AMS) are set to ON.
2 Do a check of the EMERGENCY STOP buttons:
2.1 On the control panel in the engine control room (ECR), push the EMERGENCY
STOP button.
2.2 Make sure that the pressure control and safety valve 10-5562_E0_5 is
electrically operated (ie the coil is energized).
NOTE: This causes an alarm (M/E Emergency Stop) in the AMS.
2.3 Make sure that the EMERGENCY STOP button is deactivated again.
2.4 Do Step 2.1 to Step 2.3 again with the EMERGENCY STOP buttons on the local
control panel and on the bridge.
3 Do a check of the pressure switches that follow:
•
PS1101S (pressure of cooling water at engine inlet)
•
PS2002S (pressure of main oil at engine inlet)
•
if applicable PS2012S (pressure of main oil at inlet fuel pump)
•
PS2611-nnS (pressure of bearing oil at inlet each turbocharger)
•
PS4341S (pressure of air supply to air spring)
3.1 Carefully remove the first pressure switch (for example pressure switch
PS1101S).
NOTE: The stop valve in the connection closes automatically.
3.2 Connect the pressure calibration hand-pump to the pressure switch.
3.3 Operate the pressure calibration hand-pump to increase the pressure to more
than the SHD pressure of the pressure switch.
NOTE: For the related SHD pressure refer to section 11.2 List of usual values
and safeguard settings - general.
3.4 Make sure that the pressure switch opens.
3.5 Decrease the pressure to less than the SHD pressure.
3.6 Make sure that the pressure switch closes at the related pressure.
3.7 If the pressure switch does not close, find the cause and repair the fault.
3.8 Disconnect the pressure calibration hand-pump from the pressure switch.
3.9 Install the pressure switch.
3.10 Do Step 3.1 to Step 3.9 again for the other pressure switches.
3.11 To do a test of the passive failures, temporary disconnect the sockets of the
switches that follow:
•
PS1101S
•
PS2002S
•
PS4341S
•
FS2521-nnS
4 Do a function check of the oil mist detector:
4.1 Remove a plug from the junction box, or start the Test Menu in the control unit.
4.2 Connect the smoke test instrument to the test connection of a sensor.
4.3 Simulate oil mist to activate an alarm in the safety system.
4.4 If removed, install the plug on the junction box.
5 For a DF engine, do a calibration and a function check of the gas detectors, refer to the
related documentation of the manufacturer.
