APPLICATION
The C554A Cadmium Sulfide Flame Detector (cad cell) is
a photo conductive flame detector (see Fig. 1) used with
oil primary controls such as R4166, R4184, R8182,
R8184, R8185, R8404 and R8991. It consists of a plug-in,
light sensitive cell and a socket with Type E mounting
bracket, factory-installed leadwire and an oil line adapter
bracket. Leadwire length is 60 in. (1520 mm). The detector
is installed inside the air tube of the burner where the cell
can view the flame and is wired to the F-F terminals of the
oil primary control.
The photocell is a ceramic disk coated with cadmium
sulfide and overlaid with a conductive grid. Electrodes
attached to the ceramic disk transmit an electrical signal to
the primary control. In darkness, cadmium sulfide has a
very high resistance to the passage of electrical current. In
visible light, its resistance is very low and current is
allowed to pass. The entire cell is hermetically sealed
(glass to metal) to prevent cell deterioration.

Location
The burner manufacturer determines the cad cell location
(see Fig. 2). If an alternate location must be used, make
sure that:
The cell has a clear view of the flame.
Ambient light does not reach the cell.
Ambient temperature at the cell location is below
140 F (60 C).
Movement, shielding, or radiation of metal surfaces
near the cell do not affect cell function.
