OIL FILTER - If flashing, indicates that oil filter
maintenance is needed.
POWER ON - Lit if 120VAC power is applied to the
Supervisor.
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 sequence stop, or AUTO mode Unload
Timer has expired. The compressor may start at
any time.
AUTO - If lit steady, the compressor is running in
AUTO mode. If flashing, the machine is armed to
run but is in the standby state, and may start at any
time (i.e. when line pressure drops below the load
pressure value).
6.5 SUPERVISOR OPERATING PARAMETERS-
SET UP
Pressing the program key enters parameter display
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
order:
• Unload pressure - The pressure where the ma-
chine 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).
• Load differential - The pressure differential
below the unload pressure where the machine is
loaded. For example if the unload 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).
• P1 Max - Maximum sump pressure. An alarm and
shut down will occur when the sump pressure rises
above this pressure.
• Wye to delta transition timer - For full voltage
starters this parameter is set to zero.

WYE DELT

• Restart time - Time to wait after power-up before
starting machine. This parameter is used to keep
several machines from starting at the same time
after power up, or to delay start until other equip-
ment is started. If disabled the machine will not au-
tomatically start after power up.
RST TIME
10 SEC
• Unload Stop Timer - If the machine is running in
AUTO mode, this parameter specifies the amount
of time that the machine 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 machine from being started more
than four times an hour.
UNLD TIM
15 MIN
• Language select - English, German, Spanish,
Italian and French may be selected for display lan-
guage.

ENGLISH
• Units - English or metric units may be selected.

• Communications ID # - This is the network ad-
dress of a machine. If there is more than one ma-
chine connected to the network, each machine
must have a unique number.
COM ID #
• Communications Baud Rate - This should al-
ways be selected to 9600 baud for all sequencing
modes. It may be lower for slave or monitoring
modes.
