If networking multiple fans to run using a single control
source, the dipswitch settings on each fan’s VFD circuit
board will need to be adjusted using the following
instructions.
DIPSWITCH 3
DIPSWITCH 2
First Fan
1. Determine the first fan in the network daisy-chain
by identifying the fan that is connected directly to
the control source.
2. Remove the front VFD cover from the first fan in the
network using a phillips screwdriver.
3. Dipswitch 2 is used to set parameters that improve
network function. Verify that each of the switches
on dipswitch 2 are set as follows:
Position 1 – Off
Position 2 – On
Position 3 – On
4. Dipswitch 3 is used to set unique Modbus
addresses for each fan in the daisy-chain. Adjust
positions 1-5 on dipswitch 3 to set the desired
Modbus address. A table with all possible Modbus
addresses is shown to the right.
IMPORTANT:
Positions 6 – 8 are used to set parameters
needed for fan operation and should not be adjusted.
5. Refer to instruction manual provided with HVLS
control to determine if additional networking
modifications are required. Follow instructions to
complete necessary modifications.
6. Reinstall the front VFD cover.
All Remaining Fans
1. Remove the front VFD cover using a phillips
screwdriver.
2. Set dipswitch 2 as shown below. Dipswitch 2 is
used to set parameters that improve network
function and will need to be adjusted for all fans in
the network except for the first fan.
Position 1 – Off
Position 2 – Off
Position 3 – Off
3. Adjust positions 1 – 5 on dipswitch 3 so that each
successive fan has a unique Modbus address. A
table with all possible Modbus addresses is shown
on the following page.
IMPORTANT:
Positions 6 – 8 are used to set parameters
needed for fan operation and should not be adjusted.
NOTE:
It is good practice to use successive Modbus
addresses for networked fans, but this is not necessary
for proper functioning of the network.
4. Refer to instruction manual provided with HVLS
control to determine if additional networking
modifications are required. Follow instructions to
complete necessary modifications.
5. Reinstall the front VFD cover.
