F) If the fan is turning the wrong way on initial startup, follow the procedure below:
i)
ii)
iii)
iv)
v)
vi)
vii)
Verify that the For-Off-Rev switch is in the For position.
If so, turn the switch to the Off position.
Carefully remove the remote switch box faceplate with the switches attached
and turn it over. Verify that the wiring to the For-Off-Rev switch matches the wiring
diagram (there should be a sticker inside the remote enclosure). If it's
wrong, correct it and re-test the fan. Reattach the faceplate (before testing).
If step iii does not solve the problem, turn off the disconnect switch on the MCP and snap
the small cover off the VFD. Ensure that the wiring matches the wiring diagram — this can
be found on the included control panel drawing as well as
on a sticker inside the control panel door. If this wiring is wrong, correct it, replace the
cover, and test the fan again.
If step iv does not solve the problem, simply switch any two of the three power
wires from the MCP to the fan motor, either at the MCP or at the motor. Turn the power
back on and re-test the fan.
If none of these steps fix the problem (extremely unlikely,) contact the factory for further
assistance.
Be sure the remote box is re-assembled and the cover is back on the VFD before proceeding.
G) Adjust the speed control to 9 and verify full speed operation with no Fault or Warning
indicators lit on the VFD. Contact factory if fault/warning condition occurs.
H) Close up the MCP.
I) Adjust fan speed and direction for desired operation.
