PROCEDURE
1
Do a check of the safety and alarm system as follows:
1.1
Make sure that the remote control system (RCS), the engine safety system (ESS),
and the alarm and monitoring system (AMS) are set to ON.
1.2
On the control room console and the local control panel, push the EMERGENCY
STOP button.
1.3
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. The alarm is
shown on the LDU-20 and the AMS.
1.4
Do a test of the pressure switches that follow:
•
PS1101S (pressure of cooling water at inlet engine)
•
PS2002S (pressure of main oil at inlet engine)
•
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)
1.4.1
Connect the pressure calibration hand-pump to the first pressure switch
(eg pressure switch PS1101S).
1.4.2
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
and safeguard settings - general
.
1.4.3
Make sure that the pressure switch opens.
1.4.4
Decrease the pressure to less than the SHD pressure.
1.4.5
Make sure that the pressure switch closes at the related pressure.
1.4.6
If the pressure switch does not close, find the cause and repair the fault.
1.4.7
Disconnect the pressure calibration hand-pump from the pressure switch.
1.4.8
Install the pressure switch.
1.4.9
again for the other pressure switches.
1.5
To monitor the passive failures, connect an applicable resistor between
connections 2 and 3.
•
PS1101S
•
PS2002S
•
PS4341S
NOTE:
The values of resistors that are related to the different remote controls
are given in

Do a function check of the oil mist detector as follows:
2.1
Remove a plug from the junction box, or start the Test Menu in the control unit.
2.2
Connect the smoke test instrument to the test connection of a sensor.
