5.1   Locking/Unlocking Parameters

Locking

The parameters can be locked from the handheld terminal by entering a code
number between 1 and 11 or between 13 and 9998: all settings in the electronic insert
are protected from being altered. If the code number 9999 is shown in the display,
then locking has been activated at the electronic insert by pushbutton.

Unlocking

Locking can be again cancelled by entering the code number 12. This does not apply
if the locking was activated at the electronic insert. This is indicated by the code
number 9999 in the menu field.

5.2   Tag Number

A measuring point number (

"SET TAG NUMBER"

) can be assigned to the electronic insert

by using the handheld terminal. This consists of 8 ASCII characters. This measuring
point tag serves to identify different electronic inserts connected to the same power
line as every electronic insert has to have its own unique tag number.
