machines.
COM ADDRESS – Communication address.
SEQUENCE NO. – Number of compressors in
sequencing network.
SEQ LOAD PRESS - Master machine load pressure
set point (psi, bar) at which slave compressor is
started. For example if set at 125 psi, when master
machine pressure is less than 125 psi and SEQ
DELAY time has passed, the master compressor will
command a slave machine to start and load.
SEQ UNLOAD PRESS - Master machine unload
pressure set point (psi, bar) at which slave
compressor is commanded to unload or stop. For
example, if set at 135 psi, when master machine
pressure is greater than 135 psi and SEQ DELAY
time has passed, the master compressor will
command a slave machine to unload or stop.
SEQ DELAY - Set time (sec) that master machine
allows to pass before sending a command to a slave
machine to load or unload.
