5.8 OPERATING THE COMPRESSOR
Before operating the compressor t he operating pa-
rameters must be setup. See the previous section
on operating parameter setup.
MANUAL OPERATION MODE
In this mode the compressor will run indefinitely, as
long as temperatures and pressure remain within
the valid operating ranges, and the motor overload
or emergency stop contacts are not tripped. Press-
ing the “I” will turn on the compressor and put it in
manual mode. If the compressor is already run-
ning, but in automatic mode, pressing “I”will
switch operation to manual. Pressing “I”whileal-
ready running in manual mode will cause the Su-
pervisor to turn off t he common fault relay, if en-
gaged, and clear any maintenance indicators.
To stop the compressor, press “O”Ifthecompres-
sor is already off when “O” is pressed, the common
fault relay will be turned off, if engaged, and it will try
to clear the alarm and maintenance indicators. Re-
gardless of what the compressor is doing, pressing
“O” puts the Supervisor in manual stop mode.
