DESCRIPTION
Figure 2-6 Compressor Air Inlet System
to return to the full load (maximum) position.
AUTOMATIC OPERATION
For applications with varied periods of time when
there are no air requirements, Supervisor's Auto
mode allows the compressor to shut down (time
delayed) when no compressed air requirement is
present and restart as compressed air is needed.
LOAD/ NO LOAD OPERATION
If applications call for load/no load operation, mod-
ulation can be disabled in the Supervisor
Controller in the "Control Parameters" menu. If
TM
modulation is disabled, the unload pressure must
be reset to the rated load pressure of the machine.
For example, an L model rated for 100 psig full load
operation and 110 psig unload must have the
18
unload pressure reset to 100 psig. This ensures
that the motor will not run in an overload condition.
2.7 AIR INLET SYSTEM, FUNCTIONAL DESCRIP-
TION
Refer to Figure 2-6. The compressor inlet system
consists of one or two dry-type air filters, a vacuum
switch and an air inlet valve.
The vacuum switch, located in the compressor
Supervisor control system, indicates the condition
of the air filter. When the message "AIR FILTER
MAINT RQD" is displayed,maintenance is required.
The butterfly-type air inlet valve directly controls the
amount of air intake to the compressor in response
to the operation of the Sullicon Control
2.6).
