5. ES+
This section provides details on configuration and operation of the system in ES+ sequencing.
5.1 Wiring Connections
Figure 31 below shows the wiring connections for the ES+ sequencing protocol. Note that ES+
sequencing can only be configured for fixed speed machines.
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. Unlike AirSmart and Delcos
protocol, the ES+ RS485 connections are located on the Governor display at
RS485 IF5
in the
control cabinet, as shown in Figure 32.
Figure 31: ES+ RS485 Communication Wiring Schematic
below shows how to connect a legacy ES+ machine to the Governor controller using the
6-conductor telecommunications cable that may already be included on existing ES+-controlled
machines for communications (GD PN: 97J49 for reference). The cable connects to the Governor
display at the IF5 interface using the 6-pin connector on the display with two conductors per pin as
shown. The black/yellow pair connects to terminal 4, white/blue pair connect to terminal 5, and
green/red pair connect to terminal 6. You will need to carefully strip and terminate the cable and
conductors to make the connection to the controller.
