4.5 Auxiliary Blowers
CAUTION
Equipment Hazard: Without applicable lubrication, damage can
occur to components. Before you operate the auxiliary blowers
make sure that the main lubrication oil and the turbocharger
lubricating oil supply are set to on.
Note: Do a check of the necessary lubrication oil pressure, refer to 0250−1
Operating Data Sheet.
1) Set to on the electrical power supply for each auxiliary blower.
2) On the LDU−20 MAIN page, select the button CTRL. TR. to get control at the
local control panel (see 4002−2 Local Control Panel / Local Display Unit,
paragraph 3.4).
3) Select the button START AUX. Make sure that:
a) Auxiliary blower 1 starts immediately.
b) Auxiliary blower 2 starts after an interval of between 3 seconds to 6 seconds.
4) Make sure that the two auxiliary blowers turn in the correct direction.
5) Do step 3 again from the LDU-20 in the ECR.
6) Connect the pressure calibration hand-pump (tool 94050) to the pressure
transmitters PT4043C and PT4044C. This will simulate a scavenge air pressure
(0 bar to 6.0 bar).
7) On the MCM−11 (PT4043C), disconnect the cable from X41 terminal 1
8) On the IOM−10 (PT4044C) disconnect the cable from X13 terminal 2.
9) Connect an ampere meter between the connection and the related cable.
10) 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 transmitter(s).
11) On the MCM−11 (PT4043C), connect the cable to X41 terminal 1.
12) On the IOM−10 (PT4044C), connect the cable to X13 terminal 2.
Note: The auxiliary blower start/stop hysteresis (0.8 bar to 1.0 bar) is adjusted
in the ECS.
13) Disconnect the pressure calibration hand-pump (tool 94050).
4.5.1 Test of Auxiliary Blowers from LDU−20 ECR
1) On the MCM-11, disconnect terminal X33.
2) Start the auxiliary blowers.
Note: Command and feedback of auxiliary blowers must continue to operate.
3) If the auxiliary blowers do not operate, do a check of the wiring to the starter box.
4) On the MCM-11, connect terminal X33.
5) On the IOM-10, disconnect terminal X11.
6) Start the auxiliary blowers.
Note: Command and feedback of auxiliary blowers must continue to operate.
7) If the auxiliary blowers do not operate, do a check of the wiring to the starter box.
8) On the IOM-10, connect terminal X11.
