The Capacity Control System consists of a pneu-
matic inlet valve, solenoid valve, pressure regu-
lator valves and a pressure transducer. The
functional description of the Control System is
described below in four distinct phases of opera-
tion. The following description text applies to all LS-
200S series compressors with the Supervisor
Controller. For explanatory purposes, this descrip-

tion will apply to a compressor with an operating
range of 100 to 110 psig (6.9 to 7.6 bar). A com-
pressor with any other pressure range would oper-
ate in the same manner except stated pressures.
Always refer to the machine nameplate for
designed operating pressure.
