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 II Sequenc-
ing & Protocol Manual (P/N 02250057---696).
S DISABLED --- Responds to status and
parameter change messages via the
RS485 network but will not respond to
start, stop, load or unload messages.

10---60 Min.
0---10 Min.
Duration 0---10 Sec.
S REMOTE --- Responds to status and pa-
rameter change messages but will not re-
spond to start, stop, load or unload mes-
sages. The remote inputs and outputs are
enabled (start/stop, load/unload, master/
local).
S SLAVE --- Will respond to all messages,
but will not start or load unless comman-
ded to do so by a message. This mode is
used to control the machine from a master
computer.
S HOURS --- Sends status message about
once a second, starts, loads and unloads
machines based on sequencing hours.
S COM ID # --- Sends status message
about once a second, starts, loads and un-
loads machines based on machine Com
ID#.
OPERATION
Contact closure energizes the compressor starter.
A timed contact used to provide wye---delta transition
time. Not used on DS---13 Series.
Controls ON LOAD/OFF LOAD operaton of the load
control solenoid valve.
May be used to provide remote indication of any pre---
alarm, maintenance or fault shutdown condition.
Controls a solenoid valve to provide automatic con-
densate removal.
Used with sequencing feature.

Unload pressure setting
System shutdown pressure setting
