MON is supplied by line L1.
Verify if the motor or heating unit

alternate power supply. Replace
the motor or heating unit If it still
is not operating.

heating unit is defec-
tive.
The controller is

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 controller.
