String assigned to an alarm
Each enabled alarm can be assigned an alphanumeric string composed of 5 characters, to be displayed on the
PV, SV or F 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/SV/F display.
8.8.8.8.8.
A B C D E
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.

In case of simultaneous strings on the PV display, the string corresponding to the lower alarm number has priority.
The alarm string and the display on which it appears are set by means of parameters SdS.SP, SdS.F and SdS.PV
on the Hrd menu: they are enabled with bit weight according to the number of alarm strings to be shown on each
display.
