Certain versions of the S550 were produced without a
temperature sensor. These will display zero for tem-

AUTOMATIC SETUP
The flame monitor can be configured automatically in
two different ways. Seeing that this configuration is for
a specific channel it therefore falls under the channel
menu.
Only a currently selected channel can be set up
automatically, as indicated by a red Prim/Alt display
Fit
The auto fit menu is entered by selecting AUTOMATIC
from the channel menu.
The auto fit configuration only affects the gain of the
specific sensor selected and Flame On and Flame Off
set points).
A channel utilizing 2 simultaneous sensors (S550)
cannot be calibrated with this procedure.
It is necessary to have a flame present to use auto
set.
The gain will be set so that the flame count for the
specific sensor is between 1100 and 1300. The Flame
On will be set to 800 and Flame Off to 600.
If this is unobtainable, a message will be displayed
indicating the flame is too high or too low. (High flame
requires the installation of an orifice).
Note: If a channel is using two sensors a choice will
be given to turn one or the other of these sensors
off. The corresponding gain will be set to Zero for
S550 viewing heads or the sensor will be selected
for the specific channel for advanced viewing heads
