DTI: Maximum Remote Setpoint (DTI/ Modbus/External)
If a required value command is received from the DTI or Modbus that is
above this maximum remote setpoint value, then it will be ignored by the
MM. The MM will continue to fire to meet the previous required setpoint.

EGA: Trim Delay
After ignition, the EGA does not sample for the time delay set in this option
(if EGA is set to 2 or 3). This allows for the combustion to stabilise before
sampling commences. The delay timer starts at the ignition point.

DTI: MM Identification
Each MM within a sequencing/ DTI/ Modbus/ twin burner loop must be set
with an individual ID number. For communications between the MMs,
there cannot be more than 1 MM with the same ID number.

DTI: Sequence Scan Time
This is the time period between sequencing requests from the lead and
the lag MMs. On the sequence scan time, the lead MM will demand lag
burners to be brought online or offline, depending on load requirements.
See parameters 86 and 87 for change down and up thresholds. Accurate
fuel flow metering must be entered for sequencing to operate. The MMs
must be connected using data cable (Belden 9501) screened at one end.
