2.3
Simulate oil mist to activate an alarm in the safety system.
3
For a DF engine: Do a calibration and a function check of the gas detectors, refer to the
related documentation of the manufacturer.
4
Do a check of the auxiliary blowers as follows:
4.1
Set to ON the main bearing oil supply.
4.2
If applicable, set to ON the turbocharger oil supply.
4.3
Do a check of the applicable lubricating oil pressure, refer to
values and safeguard settings - general
4.4
Set to ON the electrical power supply for each auxiliary blower.
4.5
On the LDU-20 MAIN page, select the button CTRL. TR. to get control at the local
control panel.
4.6

4.8
and
again from the LDU-20 in the ECR.
4.9
Connect the pressure calibration hand-pump to the pressure transmitters
PT4043C and PT4044C.
4.10
Operate the pressure calibration hand-pump to simulate a scavenge air pressure
of 0 bar to 6.0 bar.
4.11

4.12
On the IOM-10 (PT4044C) disconnect the cable from X13 terminal 2.
4.13
Connect an ampere meter between the connection and the related cable.
4.14
Make sure that the transmitter output (4 mA to 20 mA) is related to the simulated
pressure (0 bar to 6.0 bar). If necessary replace the applicable transmitter.
4.15
On the MCM-11 (PT4043C), connect the cable to X41 terminal 1.
4.16
On the IOM-10 (PT4044C), connect the cable to X13 terminal 2.
