DAISY CHAINING
B
When you first apply power to
the HMI, it will ask how many
fans on the circuit. All other
critical programming is done
by Hunter.
C
The input cable should plug into Comm 1 on the first
connected VFD Control Panel. When connecting to a second
fan connect the cable to Comm 2 (as an output) and connect it
to Comm 1 as an input to the subsequent fan. Repeat for more
fans in series where Comm 1 is the input and Comm 2 is the
output. Note that Comm 2 will not be connected on the final
fan.
When daisy chaining fans with one control, the layout will be similar to the one below:
A
You will have one Cat5e
cable from the HMI to the
Drive of the first fan:
NOTE
Must use shielded Cat5e-6 cable for connections with a
maximum distance of 300 ft of cable for daisy chaining
