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).

Carefully remove the first pressure switch.
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. Repeat this step for each pressure
switch.
NOTE:
For the related SHD pressure refer to section
[section not applicable for
this engine]
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
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.
6
Do a check of the auxiliary blowers:
6.1
Make sure that main bearing oil is available.
6.2
If applicable, set to ON the turbocharger oil supply.
6.3
Do a check of the applicable lubricating oil pressure, refer to section
[section not
applicable for this engine]
