interconnect cable is

properly.

The mist unit is
defective.

defective.
Replace the fuse.
Make sure the cable is firmly
plugged in with the tabs in place.
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, make
sure the Stage's COMMON is
supplied by line L1.
Verify if the motor is defective
by connecting it to an alternate
power supply. Replace the
motor If it still is not operating.
Listen to see if there is a clicking
sound when the zone pilot light
turns on. If there is no clicking
sound, contact your distributor to
repair the controller.
