SOLUTION
The Stage's fuse is

Replace the fuse.
The display board
interconnect cable is
not plugged into the
power supply board
properly.
Make sure the cable is firmly
plugged in with the tabs in place.
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 or
heating unit. Also, make sure the
Stage COMMON is supplied by
line L1.
Verify if the motor or heating unit
is defective by connecting it to
an alternate power supply.
Replace the motor or heating
unit If it still is not operating.
The fan motor or
heating unit is
defective.
The controller is
defective.
Listen to see if there is a clicking
sound when the Stage's pilot
light turns on. If there is no
clicking sound, contact your
distributor to repair the control-
ler.

ing.
