presence of an alarm.
MOTOR -- If flashing, indicates the motor overload
contact has opened.
INLET FILTER -- If flashing, indicates that inlet filter
maintenance is needed.
OIL FILTER -- If flashing, indicates that oil filter
maintenance is needed.
POWER ON -- Lit if 120VAC power is applied to the
Supervisor II.
ON -- If lit steady, the compressor is running. If flash-
ing, indicates that the compressor is armed but
stopped because of restart timer not expired, re-
mote stop or sequence stop. The compressor may
start at any time.
AUTO
-- If lit steady, the compressor is running and
in auto mode. If flashing, indicates that the compres-
sor is armed but stopped because of restart timer
not expired, remote stop or sequence stop. The
compressor may start at any time.

OPERATING PARAMETERS--
SET UP
Pressing the program key enters parameter dis-
play and edit mode. To move to the next parameter
press the program key. To increment a parameter
press the up arrow key or logo key. The logo key
will increment by 10. To decrement the value press
the down arrow key.
The parameters are displayed in the following or-
der:
S
Unload pressure --- The pressure where
the machine is unloaded. For example if
this parameter is set to 110 psi (7.6 bar) the
machine will unload when the line pressure
is above 110 psi (7.6 bar).
UNLOAD
100 PSI
S
Load differential --- The pressure differ-
ential below the unload pressure where the
machine is loaded. For example if the un-
load pressure is set to 110 psi (7.6 bar) and
the load differential is set to 10 psid (0.7
bar), the machine will load when the line
pressure goes below 100 psi (6.9 bar).
LOAD
10 PSI
S
P1 Max --- Maximum sump pressure. An
alarm and shut down will occur when the
sump pressure rises above this pressure.
P1 MAX
135 PSI
S
Wye to delta transition timer
--- For full
voltage starters this parameter is set to
zero.
WYE DELT
10 SEC
S
Restart time --- Time to wait after powerup
before starting machine. This parameter is
used to keep several machines from start-
ing at the same time after power up, or to
delay start until other equipment is started.
If disabled the machine will not automati-
cally start after power up.
RST TIME
10 SEC
S
Unload Stop Timer --- If the machine is
running in AUTO mode, this parameter
specifies the amount of time that the ma-
chine will run unloaded before shutting off.
If the time is set less than 15 minutes (five
minutes, for example), there may be times
when the machine will run unloaded for
more than five minutes. This is because
there is another timer that keeps the ma-
chine from being started more than four
times an hour.
UNLD TIM
15 MIN

Communications ID # --- This is the net-

than one machine connected to the net-
work, each machine must have a unique
