Alarms Tables
The Alarms table is used to set min and max alarm thresholds for each of the 8 sensor
inputs. After the analog conversion and digital averaging, the 10 bit vales are scaled to 8-bit
values and used to perform a lookup of actual display values from the Calibration tables. 8-
bit digital values have a range from 0 to 255. Every sensor input is scaled to this range. Min
alarms are defined as being tripped when the scaled sensor value is below the min set point.
Max alarms are defined as being tripped when the scaled sensor value is above the max set
point.

The first row identifies the file as a table specifier ([TABLE]) followed by the starting
address in memory to load the table ([7800]), followed the length in bytes contained on each
row ([1]) followed by the number of rows ([128]). None of the values in the first row can be
modified.
The following 16 rows contain the alarm value pairs used for each sensor. Each alarm value
must start with “db ‘” and end with “’;”. This can not be modified. Each label must contain
exactly 1 hex byte starting with a “%” symbol and followed by two hexadecimal characters.
In hexadecimal notation %FF is equ
al to 255 decimal. Anything after the “;”character is
considered a comment and ignored.
