System information

All values are represented in a HEX or base 16 format.
GSTAT determines the type of value TIMER represents. TIMER can be a running timer such as is
used in purge, a flame signal or meaningless. Only the lower nibble of GSTAT has any value. If this
value is 0 then the TIMER value has no meaning. The value in TIMER is a background minute timer
in the Flame-Monitor and should be ignored. If GSTAT is between 4 and 7, the TIMER represents
the current value flame signal. If GSTAT is a 1, 2, or 3 then TIMER represents a running timer value.
The baud rate of the Flame-Monitor is fixed at 4800 bits per second. The format of the data is 8 data
bits, no parity and 1 stop bit. Due to the RS485 format, the communication format is considered half-
duplex. That is, only one user is permitted on the communication lines at a time.
The information contained in INPUTS and OUTPUTS represents the status of the interlocks and
relays respectively. For the INPUTS, a 1 in the interlock position defines the interlock as being on or
active where a 1 in any bit position in the OUTPUT register signifies the relay as being energized.
INPUTS
A ‘1’ in the opto-coupler position indicates the opto-coupler is on or interlock closed.

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.
