Options 48.1 to 48.7 - Smoke level high alarm values (0.0 – 99.9%)*
Option parameter 48.0 is only available if option 47.0 (smoke input select) is not set to zero.
If option 48.0 is set to 0, the smoke level high alarm is disabled.
If option 48.0 is set to 1, the smoke level high alarm is enabled and option parameters 48.1 to 48.7
become available.
Using option parameters 48.1 to 48.7, it is possible to set a different smoke level high alarm value for
each profile combination. Each option parameter may be set to any value between 0 and 99.9%
inclusive.
If the burner is firing, it is only possible to make an adjustment to the option parameter which relates
to the selected profile combination. If the burner is not firing, the high alarm value for any profile
combination may be adjusted.
If the smoke level exceeds the high alarm value for the selected profile combination, a fault number
will appear. See section xxx for details of fault numbers.
Option 49.0 - NOx input select (0/1)*
Option 49.1 - NOx input zero value (0 – 999)*
Option 49.2 - NOx input span value (0 – 999)*
Option 49.0 is only available if a flue monitor interface (FMI) board is fitted in option slot 2, and the
options are as follows:
0
- NOx sensor not fitted
1
- NOx sensor connected to 4-20mA NOx input (PM15-16).
If option 49.0 is set to 1, options 49.1 & 49.2 give the zero and span values for the input. There are
the measured values that are displayed when 4mA and 20mA appear at the 4-20mA NOx input
(PM15-16) on the FMI board.
Note: The values entered for these option parameters are in units of x10 p.p.m, and therefore an
entered value of 999 means 9990 p.p.m.
Option 50.0 - NOx level high alarm select (0/1)*
Options 50.1 to 50.7 - NOx level high alarm values (0 - 999)*
Option parameter 50.0 is only available if option 49.0 (NOx input select) is not set to zero.
If option 50.0 is set to 0, the NOx level high alarm is disabled.
If option 50.0 is set to 1, the NOx level high alarm is enabled and option parameters 50.1 to 50.7
become available.
Using option parameters 50.1 to 50.7, it is possible to set a different NOx level high alarm value for
each profile combination. Each option parameter may be set to any value between 0 and 999 inclu-
sive, in units of x10 p.p.m. Remember that the NOx zero and span is entered in units of x10 p.p.m.
If the burner is firing, it is only possible to make an adjustment to the option parameter that relates to
the selected profile combination. If the burner is not firing, the high alarm value for any profile com-
bination may be adjusted.
If the NOx level exceeds the high alarm value for the selected profile combination, a fault number
will appear. See xxx for details of fault numbers.
Option 51.0 - SOx input select (0/1)*
Option 51.1 - SOx input zero value (0 – 999)*
Option 51.2 - SOx input span value (0 – 999)*
Option 51.0 is only available if a flue monitor interface (FMI) board is fitted in option slot 2, and the
options are as follows:
0
- SOx sensor not fitted
1
- SOx sensor connected to 4-20mA SOx input (PM17-18).
