all slaves are loaded, the master will allow the system to run up to 100% load to maintain the
target pressure.
2. If the master and one or more slaves are running, the master will keep the system running at
or above the Transfer Load Decrement percent load. If the system pressure rises above the
Unload Pressure setpoint, the master will command one slave to unload. If needed, more
machines will be commanded to unload, waiting Transfer Interval seconds between each
command. If all slaves are unloaded (only the master is running), the master will run down to
its minimum speed to attempt to maintain the target pressure. If the master is running at
minimum speed and the system pressure rises above the unload pressure, the master will
unload.
Note that only variable speed machines can accept a speed command from the master. Also, a
fixed speed master cannot send a speed command other than 100% to slave machines. If there
are any variable speed machines on the network, the system will operate most efficiently if the
largest variable speed machine is the master of the group.
3.7 AirSmart Sequencing Diagnostics
The Sequencing Diagnostics page can be found by going to Menu, then selecting Diagnostics, then
Sequencing as shown in Figure 16
below. This page shows the status of the network and each
individual compressor.
Figure 16: AirSmart Sequencing Diagnostics Menu Navigation
The information on the Sequencing Diagnostics page for AirSmart mode is shown in Figure 17
below. This page gives an overview of the sequencing operation for the network. The compressor
name, run hours, capacity, and operating pressure is also shown at the top of this page. As more
