5
For main ON, another for running fan/ blower, third one for
running of furnace.
Phase Control Thyristor:
Both be set as manual and pid mood (If PID Controller)
parameter through Pid temperature controller. Manual
mood drive through pot seting on front panel of furnace.
Thyristor Feature-
Soft-start, soft-stop
Small compact size
Led monitoring (depend on model of furnace)
Over current trip
o/p voltage setting
Single Phase 220v A/c.
Two Phase Three wire 440V A/c.
Three Phase 440v A/c.
Contactor/SSR:
For ON & OFF temperature process one contactor or ssr
relay will be provide in panel of furnace to control smooth
drive of temperature controller( only for manual thyristor
derive). Value of contactor or ssr will be depend upon size
of hot chamber and heating elements.
