ENGINE ROOM NO. 1 PANEL
Figure 5-2 shows the engine No. 1 panel
divided into five sections for engine room No. 1.
These sections are labeled RDCN GEAR LUBO,
CRP, FUEL OIL, GTM 2B (including alarm,
manual start push-button indicators, and torque
and LO pressure meters for both GTMs), and
LUBE OIL.
RDCN GEAR LUBO Section
The first section on the panel, the RDCN
GEAR LUBO section, is used to monitor the
MRG LO system. It has an alarm indicator and
a pressure meter. The parameters for this panel
are sensed at the lower outboard first reduction
gear bearing. The alarm indicator set point is 5
psig. The meter reads 0 to 25 psig. Because there
is a certain amount of head pressure in the LO
supplied to this bearing and its sensor, the meter
tends to read 1 to 3 psig higher than actual LO
header pressure.
