Burner Control Type Codes
The burner control type code indicates the exact model
number of the burner control. See Table 19.
Table 19. Burner Control Type Codes.
7800 SERIES Burner Control State Bits
The burner control sequence state is translated into State Bit
Register as shown in Table 20.
7800 SERIES Sequence State Codes
Sequence state codes are provided by the Burner Control.
Each code is translated into two string codes for displaying an
associated message in two lines. Each code is also translated
into burner control state bits which may be used to generate
and control system diagrams on an operator interface. The
codes can also be retrieved from registers 40004, 40005, and
40013.
The Sequence State Codes shown in Table 21 are valid only if
the Fault Code has a value of zero. If the Fault Code is non-
zero, the sequence state field contains the sequence state
code when the lockout occurred.
