Problem: One or more fans not found by control.
1
Were fans and controls installed using only the provided
networking components (green shielded CAT-5e cables,
black shielded 3-way RJ45 splitters) or components that
comply with specifications on page 34?
Yes
No
Networking components may be defective, incorrectly
wired, or do not meet required specifications.
Replace
with provided components or components that comply
with specifications on page 34.
2
Does communication wiring on VFD of fan 1 (directly
connected to control via shielded CAT-5e cable) match the
wiring diagram for fan 1 on pages 36-37?
Yes
No
Communication wiring on fan 1 is incorrect.
Turn off
supply power to fan and correct wiring as shown in wiring
diagram on pages 36-37. Then turn supply power on.
3
Are the dipswitches on VFD of fan 1 (directly connected to
control via shielded CAT-5e cable) set as shown for fan 1
on pages 36-37?
Yes
No
Incorrect dipswitch settings on fan 1.
Adjust dipswitches
as shown on pages 36-37. All fans must have a unique
Modbus address setting on dipswitch bank 3.
4
Is LED 8 on the bottom right side of the VFD on fan 1
blinking?
Yes
No
Solid light indicates need to restart VFD.
Cycle power to
VFD. If solid light persists, contact factory.
5
Is LED 8 on the bottom right side of the VFD on fan 1
blinking approximately one time per second?
Yes
No
Blinking faster than one time per second indicates
no communication with control.
Unplug and reconnect
shielded CAT-5e cable connections between control and
fan 1 to ensure that cables are fully seated (will hear a
“click” when fully seated). If rapid blinking persists, test
shielded CAT-5e cables for functionality and replace faulty
cables (if applicable). Otherwise, contact factory.
6
Does communication wiring on VFD of fan 2 (directly
connected to fan 1 via shielded CAT-5e) match the wiring
diagram for “all remaining fans” on pages 38-39?
Yes
No
Communication wiring on fan 2 is incorrect.
Turn off
supply power to fan and correct wiring as shown in wiring
diagram on pages 38-39. Then turn supply power on.
7
Are the dipswitches on VFD of fan 2 (directly connected
to fan 1 via shielded CAT-5e cable) set as shown for “all
remaining fans” on pages 38-39?
Yes
No
Incorrect dipswitch settings on fan 2.
Adjust dipswitches
as shown on pages 38-39. All fans must have a unique
Modbus address setting on dipswitch bank 3.
8
Is LED 8 on the bottom right side of the VFD on fan 2
blinking?
Yes
No
Solid light indicates need to restart VFD.
Cycle power to
VFD. If solid light persists, contact factory.
9
Is LED 8 on the bottom right side of the VFD on fan 2
blinking approximately one time per second?
Yes
No
Blinking faster than one time per second indicates
no communication with control.
Unplug and reconnect
shielded CAT-5e cable connections between fan 1 and fan
2 to ensure that cables are fully seated (will hear a “click”
when fully seated). If rapid blinking persists, test shielded
CAT-5e cables for functionality and replace faulty cables (if
applicable). Otherwise, contact factory.
10
After repeating steps 6-9 for all remaining fans, can all fans
be found using autodetect feature on control?
Yes
No
Contact factory.
Everything is working properly.
