the hydraulic oil temperature switch. The compressor fan
is turned on by the compressor oil temperature switch.
The compressor cooling
compressor lubricant temperature to be maintained to a
minimum of approximately 160°F (71°C). The elevated
temperature forces the moisture, which may be ingested
into the compressor system due to atmospheric humidity,
to stay in a state of vapor. This prevents the moisture
from condensing out in the system and contaminating the
lubricant.
The cooler core for the 300 Series Power System relies
on the cooling fan to draw fresh air from outside the
package across the core to cool the compressor
lubricant. The maximum lubricant temperature is
maintained by using an integral compressor thermal
valve.
The oil cooling system is composed of the following main
components:
PRESSURE SWITCHES
See Figure 2-8. The compressor is equipped with two
switches that can shut down the unit should over-limit
conditions occur. The temperature shuts down at 240°F
(116°C). The pressure switch shuts down machine at 185
psi.
See Figure 2-9. The compressor system is also supplied
with a spin-on oil filter, positioned off the lower corner of
the compressor. This
replacement to prolong the life of the compressor
system. For routine maintenance of the spin-on filter,
consult Sections 6.2 and 6.3 for maintenance schedules,
and Section 6.6.4 for specific compressor oil filter
maintenance procedures.
The drive systems from the motor to both the compressor
and generator are accomplished with two micro V-belt
systems. Both of these systems have provisions for belt
tensioning, should the belts become stretched out over
time (refer to Section 6.6.15).
See Figure 2-10. The AC generator utilized on the 300
Series package is a 2-pole, single phase, 2-bearing,
