Question

Can Temperature Controllers with a heater burnout alarm detect heater burnouts when using thyristor control?

Answer

No, it cannot.
When thyristor control (phase control) is used, the control output is a current output. Therefore the heater burnout alarm of the Temperature Controllers cannot be used.

See whether any of the following methods can be used.

Use G3PX Digital Controllers with Heater Burnout Detection.

Applicable models:

Single-phase:

G3PX-[][][]EH-CT[][]
G3PX-[][][]EHN-CT[][]
G3PX-[][][]EC-CT[][]

Three-phase:

G3PX-[][][]DH-CT[][]
G3PX-[][][]DC-CT[][]

Use an external Heater Burnout Detector.

Applicable models: K8AC-H1[]P[]-FLK Digital Heater Element Burnout Detectors
