5.6 OPERATING THE COMPRESSOR

Before operating the compressor the operating pa-
rameters must be setup. See Section 6.3, Supervi-
sor II Operating Parameters--- Setup, 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" while al-
ready running in manual mode will cause the Su-
pervisor to turn off the common fault relay, if en-
gaged, and clear any maintenance indicators.
To stop the compressor, press "O". If the compres-
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.
AUTOMATIC OPERATION MODE
In this mode the compressor will start if line pres-
sure (P2) is less than the LOAD parameter. It will
stop if the compressor runs unloaded for the num-
ber of minutes indicated by the UNLD TIM parame-
ter . To put the compressor in automatic mode
press " ". If P2 is already less than LOAD the com-
pressor will start immediately, otherwise the sys-
tem status will indicate STANDBY and the LED
marked AUTO will flash.
If the compressor is already running, but in continu-
ous mode, pressing "
automatic. Pressing " " while already running in
automatic mode will cause the Supervisor to turn
off the common fault relay, if engaged, and clear
any maintenance indicators.
In automatic mode the compressor can be
stopped manually by pressing "O". Stopping the
compressor using "O" will put the Supervisor in
manual stop mode.
Regardless of whether in "automatic" or "manual"
mode, control of the load solenoid will be based on
the parameters UNLD and LOAD. This operation is
as follows:
