EXPLANATION OF LOGSTAT
LOGSTAT is an indication of what logic module the control is currently operating in during its cycle
and is used for diagnostic purposes only. If a lockout occurs the current value of LOGSTAT is stored
as part of the lockout information. The message displayed corresponds to the current logic module.
Table 6:
Logstat represents the current software module the BurnerLogix is currently executing.
The BurnerLogix outputs the current displayed message as well as the historical lockout messages as
numbers. The table below correlates the message number with the actual displayed text message.
