PROBLEM
CAUSE
The wiring is incorrect.
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.
