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.
SEQUENCING MODES
The following is a brief description of sequencing
modes, for details see the Supervisor Sequencing
& Protocol Manual (P/N 02250057-696).
• DISABLED - Responds to status and parameter
change messages via the RS485 network but will
not respond to start, stop, load or unload mes-
sages.
• REMOTE - Responds to status and parameter
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 mes-
sage. This mode is used to control the machine
from a master computer.
Slave mode is not recommended for operational
usage. Consult Factory for further details.
• 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#.
EMERGENCY STOP SWITCH
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.

Contact closure energizes the compressor starter.
A timed contact used to provide wye-delta transition time.
Controls ON LOAD/OFF LOAD operation of the load control
solenoid valve.
May be used to provide remote indication of any pre-alarm,
maintenance or fault shutdown condition.
Deluxe only - controls a solenoid valve to provide automatic
condensate removal.
Deluxe only - used with sequencing feature.

RELAY OPERATION
NOTE: All output relays will handle 8 amperes at 120/240 VAC.
6.9 MAINTENANCE INTRODUCTION
As you proceed in reading this section, it will be
easy to see that Maintenance Program for the air
compressor is quite minimal. The Supervisor moni-
tors the status of the air filter, fluid filter, and sepa-
rator elements. When maintenance to these de-
vices is required, the Supervisor will display the ap-
propriate maintenance message and flash the loca-
