Flame controller Siemens LGA52... for the startup and supervision of atmospheric gas burners
of small to medium capacity (without fan) in intermittent operation, with the flame supervision by an ionization probe.
Specifications:
- Complete reference: LGA52.150B27, LGA52.171B27
- Plug-in design, suitable for installation in any position on
burners, in control cabinets or on control panels
- The housing is made of impact-proof, heat-resistant plastic and accommodates: the thermal sequencing device (ambient temperature-compensated) acting on a
multiple snap action switching system, the flame signal amplifier with the flame relay, and the lockout warning lamp and lockout reset button (splash-proof).
- Undervoltage detection: in the event mains voltage drops below about AC 165 V, an electronic circuit ensures that the gas burner control will prevent burner startup or – without releasing fuel – lockout will be initiated.
