7. Set the Communications Active Remote Control to
“ETHERNET” for each compressor.
8. Apply these settings before exiting the Conguration
screen.
9. Enable the compressor sequencing.
10. Assign a Network Name for sequencing.
11. Apply these settings and exit the screen.
NOTE
Ethernet settings should be set before setting
compressor sequencing settings in the conguration
screen. Available devices in the same network
would be automatically added to compressors
device list when sequencing option is enabled from
conguration screen.
At this point the compressor will begin multicasting its
status information over the network at a rate of every 20
seconds. (After all the Compressor is congured, the in-
formation will be populated in the Sequencing menu of
the all Compressor). Exit out of the conguration screen
and then put other compressors in Auto Seq Stand-By
mode by pressing Start->Seq Stand-By, see Figure 19-11.
After Pressing the Seq Stand-By button, the main win-
dow top status bar will display run mode as “Seq Stand-
by” and “Auto Seq Stand-by” message on top banner, see
Figure 19-12. When other compressors are placed in seq
standby then press start->Auto Seq button to start com-
pressor sequencing. When Compressor gets chance to
run based on the set priority, the main window top sta-
tus bar will display run mode as “Auto Seq”, see Figure
19-13. The compressor can get out from sequencing
by pressing Stop button from Main Screen. Compressor
can again be part of sequencing network by selection of
Auto Seq or Seq Stand-by option, see Figure 19-11.
