String assigned to an alarm
Each enabled alarm can be assigned an alphanumeric string composed of 5 characters, to be displayed on the PV
in level 1.
The string of alarm n (with n from 1 to 10) is enabled by means of parameter At.n = +512 (to display the string
when the alarm trips) or At.n = +1024 (to display the string when the alarm limit is exceeded in case of alarm with
time delay).
The string is composed of parameters SdA.n, Sdb.n, SdC.n, Sdd.n and SdE.n, which define characters A, B, C, D
and E of the PV display.
8.8.8.8.8.

The 8 parameter set bits identify the 7 display segments and the decimal point; they are shown below in decimal
values to be added, corresponding to the segments to be switched on.
Example: to compose character “3” you have to set the parameter corresponding to the value 1+2+4+8+64 = 79
The table with the settings corresponding to the most-used characters appears below.
