Cadmium Sulfide Flame Detector

FEATURES

• Cadmium sulfide sensing element provides faster

response than bimetal sensors.

• On flame failure, the cad cell causes the oil primary

control to shut down the main burner.

• Mounting brackets available to fit all applications.

• Entire cell is hermetically sealed (glass to metal) to

reduce cell deterioration by humidity, soot, or oil

fumes.

• Plug-in cell for easy replacement.

• Recessed cell provides more accurate flame sighting

and prevents accumulation of dirt and soot on cell

face.

C554A CADMIUM SULFIDE FLAME DETECTOR Mounting Oil Line Mounting for SUPER TRADELINE® and TRADELINE® Models Direct Replacement for Standard Models If desired, mount the C554A on the oil line using the oil line adapter bracket and the mounting bracket that give the C554A the best view of the flame (SUPER TRADELINE®) or use the mounting bracket provided (TRADELINE®). Mount the C554A at the rear of the burner. The mounting bracket can be bent to fit, if necessary.

C554A CADMIUM SULFIDE FLAME DETECTOR 쐋 While holding the mounting bracket in the slot, insert the screwdriver in the other end of the slot (Fig. 4). Bend the screwdriver, first to the left and then to the right, to crimp the end of the mounting bracket and hold it in position. OPERATION The C554A Cadmium Sulfide Flame Detector consists of a plug-in, light-sensitive cell and a socket with leadwire. The photocell is a ceramic disk, coated with cadmium sulfide and overlaid with a conductive grid.

CHECKOUT To check cad cell operation, use the following procedure: 쐃 Disconnect the cad cell leadwires; then start the burner. Shortly after the burner starts, place a temporary jumper between terminals F-F. Connect an ohmmeter across cad cell leadwires; resistance should be less than 1600 ohms.
