Figure 32: Legacy ES+ RS485 Communication Wiring to Governor Display
Alternatively, the 6-conductor cable can be used to connect the ES+ to the Governor display using
the RJ-12 connector shown below in GD Kit
324AUX6028
in
Table 5. Connect the cable between
the RJ-12 terminal breakout and Governor Display at the IF5 interface as shown in Figure 32
above.
The terminal breakout has a total of six terminals to wire into corresponding to the six wires on the
telecommunications cable connected to the ES+ controller. The signal pinout for this board will be
as follows: Pin 1: RS485 GND, Pin 2: RS485 +, Pin 3: RS485 -. Use a communications cable such
as 97J93 to wire from these terminals to the Governor controller on IF5. Connect a 6-wire
telecommunications cable between the ES+ controller on one of two RJ-12 jacks and the RJ-12
connector on the terminal breakout. Mount the terminal breakout board on the DIN rail in the ES+
compressor control box.
For installations with more than two units, the pigtail plug in one of the ES+ RJ-12 ports must be
disconnected on all controllers except the two at each end of the communications line. The order of
interconnection has no effect on the operation.
