Flame Safeguard (MM80001/FSG) Manual
EGA: O
2
Lower Limit Offset
If the current O
2
value is below this offset limit from the commissioned
value, an alarm/warning (see option 13) will occur, with option 12 set to 3.
EGA: CO
2
Lower Limit Offset
If the current CO
2
value is below this offset limit from the commissioned
value, an alarm/warning (see option 13) will occur, with option 12 set to 3.
If the current O
2
value is below this absolute limit, an alarm/warning (see
option13) will occur, with option 12 set to 3.
If the current CO
2
value is above this absolute limit, an alarm/warning
(see option 13) will occur, with option 12 set to 3.
If the current CO value is above this absolute limit, an alarm/warning (see
option 13) will occur, with option 12 set to 3.
The trim threshold is an offset from the required setpoint; if the actual value
is below this offset, then the EGA will not trim. This option should be set to
0 if trim is to be effective at all times during firing, and/or if external
modulation is optioned. No single point changes can be made if the actual
value is below this trim threshold.

load detector set in option 1 and metric/imperial units set in parameter 40)
Golden start allows an optimum ignition position to be set in the fuel-air
curve, which is not necessarily low flame or part of the standard modulating
index. Parameter 15 sets how long golden start position is maintained and
from which point to start counting down.
Enabled. Time counted from point of main flame
Enabled. Time counted from ignition
DTI: Minimum Remote Setpoint (DTI/ Modbus/External)
If a required value command is received from the DTI or Modbus that is
below this minimum remote setpoint value, then it will be ignored by the
MM. The MM will continue to fire to meet the previous required setpoint.
