to the inlet valve causing the check spring in the
inlet valve to close the air inlet valve. This sends a
pressure signal to the blowdown valve causing it to
open and vent the pressure in the system. After the
pressure is vented, the blowdown valve spring
returns the blowdown valve to the closed position.
2.7 AIR INLET SYSTEM, FUNCTIONAL DESCRIP-
TION
The compressor
inlet system
consists of
two air
filters
, a c
ompressor air inlet valve
and
inter-
connecting piping
to the engine and compressor.
Also,
nylon tubing
from air filter
restriction indi-
cator gauges
on instrument panel are provided.
The
air filters
are
2-stage units
with a
safety ele-
ment dry element-type filter
. This filter is capable
of cleaning extremely dirty air. However, in such
cases, frequent checks of the air filter will be
required. Referring to the instrument panel, the
engine air filter restriction gauge or the compressor
air filter restriction gauge will indicate when restric-
tion of the air passing through the filter becomes too
high.
At this time, change the air filter element. See
Section 5 for Air Filter Maintenance Procedures.
These indicators should be checked daily, after
start-up under normal conditions.
The compressor air inlet valve controls the amount
of air intake of the compressor in response to the air
demand.
2.8 INSTRUMENT PANEL GROUP, FUNCTIONAL
DESCRIPTION
. The instrument panel group
consists of an
EMS
(
E
ngine
M
onitoring
S
ystem).
On the
EMS unit
there are ten warning lamps avail-
able for system related diagnostics. These diag-
nostics can be used for system performance moni-
toring. They are located on the main EMS unit in
two rows of five: coolant temperature, intake mani-
fold temperature, fuel temperature, battery voltage,
accessory temperature, engine oil pressure, fuel
pressure, coolant level, engine derate, and acces-
sory pressure. See Figure
for functional
lamps.
Beneath the warning lamps is a digital LCD display
to scroll through different engine and machine
parameters. Digital readouts are as follows:
