Purpose Of Controls- Supervisor - Sullair LS-100L Operator's Manual

ning 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 "
pressor using "
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:
P2 > UNLD --> load solenoid turned off
P2 < LOAD --> load solenoid turned on
POWER FAILURE RESTART
If the restart timer (RST TIME parameter) is dis-
abled the compressor will not try to start after a
power up. If this time is set to a value, the machine
will go into standby after power up. When the line
pressure drops below the load setpoint, the restart
timer will start timing. When the timer expires the
machine will start.

• DISABLED
parameter change messages via the RS485
network but will not respond to start, stop,
load or unload messages.
• REMOTE - Responds to status and param-
eter change messages but will not respond
to start, stop, load or unload messages. The
remote inputs and outputs are enabled
(start/stop, load/unload, master/local).
• SLAVE - Will respond to all messages, but
will not start or load unless commanded to
do so by a message. This mode is used to
control the machine from a master comput-
er.
• HOURS - Sends status message about
once a second; starts, loads and unloads
machines based on sequencing hours.
• COM ID # - Sends status message about
once a second; starts, loads and unloads
machines based on machine COM ID#.
PURPOSE
Pushing in this switch, found adjacent to the Supervisor,
cuts all AC outputs from the latter and de-energizes the
starter. A fault message (E STOP) is displayed by the
Supervisor until the button is pulled out and the "O" pad
is depressed.
Shuts the compressor down when the compressor dis-
charge temperature exceeds 240ºF (116ºC). Continually
monitors air/fluid mixture discharged from the compres-
sor unit.
Shuts the compressor down when the compressor dis-
charge pressure exceeds P1 MAX. Continually monitors
the discharge pressure of the compressor unit. Indicates
pressure in compressor sump upon start-up to verify rotor
motor rotation.
Continually monitors service line pressure. When line
(Service Line Pressure) pressure reaches the UNLOAD
setting, the Supervisor control signals the solenoid valve
to unload the compressor.
