3. Sequencing Using the AirSmart
™ Protocol
This section describes how to connect and configure machines using the AirSmart
™ protocol.
3.1 Wiring Connections
-
Example machine wiring connections for the AirSmart sequencing protocol are detailed below. A
System Pressure feedback input is required for AirSmart sequencing. However, if desired, the
Delivery Pressure of the compressor may also be configured for sequencing in some cases and is
explained in more detail below this section. The pressure transducer wiring to the Governor
controller IO Module can be found in Figure 4
using the cable provided in the sequencing kit. The
compressor network may be comprised of any combination of Governor, AirSmart, and AirSmart
G2 controlled machines, as well as ES+ machines equipped with a PCM module.

Daisy chain the RS485 connections from the master machine to the first slave machine then
second slave machine, etc. for each machine in the sequenced group. The AirSmart RS485
connections are located on the IO Module at X02 in the control cabinet. The wiring diagram is
shown in Figure 5. RS485-2 at X03 on the IO module can also be used if present on the machine.
Setup and configuration for RS485-2 is identical to RS485-1.
