SOLUTION
PROBLEM
CAUSE
The wiring is incor-
rect.
Correct the wiring. In particular,
make sure two different lines are
connected to each motor: line L1
modulated by the controller
should be combined with another
line (N for 115V or L2 for 230V) to
activate the motor. Also, be sure
the Stage 1 COMMON is supplied
by line L1.
The Stage's fuse is
open.
Replace the fuse.
Make sure the cable is firmly
plugged in with the tabs in
place.
The display board
interconnect cable is
not plugged into the
power supply board
properly.
The fan motor is
defective.
Check if motor is defective by
connecting it to an alternate
power supply. Replace the
motor if it still doesn't operate.
The minimum speed
is too low.
Adjust the minimum speed to a
higher value.
Stage 1 fans
are not
running.
