Operation
Over-Temperature Warning LED (Red)
Turns ON at 160°C ±5°C, i.e. a range of 155°C to 165°C ( 311°F to 329°F)
Turns OFF at 125°C ±5°C, i.e. a range of 120°C to 130°C (248°F to 266°F)
Over-Temperature Protection
Reset Device
Transformer output turns OFF at temperatures of 160°C ±5°C,
i.e. a range of 155°C to 165°C (311°F to 329°F).
The transformer output breaker can be turned ON manually when the
warning light turns OFF.
