The gas burner controls are of 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 and flame-retarding plastic.
It is of plug-in design (measuring 91 x 62 x 63 mm, including the plug-in base) and
engages audibly in the plug-in base.
The color of plastic material of burner controls LGA are executed in black.
The housing accommodates the ...
... the thermal sequencing device (ambient temperature-compensated) acting on a
-
multiple snap action switching system,
... flame signal amplifier with the flame relay
-
... lockout reset button with its integrated signal lamp (splash-proof)
-
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.
Undervoltage threshold: AC 178 V ±10 V
«TSA»: Smaller tolerance band
Flame signal amplifier: Higher sensitivity, for typical applications with pilot flames
The type references given in the table refer to gas burner controls with no base and no
accessories.
For ordering information for plug-in bases and other accessories, see Accessories.
