2.4.1 TABLES OF SETTINGS

The DBF system has two types of settings stored in non-volatile memory (information is kept even when there is no auxiliary voltage):

∙Generic Settings.

∙Specific Settings.

The Generic settings are grouped as follows:

GENERAL SETTINGS

BREAKER SETTINGS

ACTIVE TABLE SETTINGS

OSCILLOGRAPHY MASK

FUNCTION PERMISSION

For the specific settings, the DBF allows to have up to 3 independent setting tables. These specific settings are grouped as follows:

50BF SETTINGS INTERNAL ARC SETTINGS

Only one setting table is active at a given time, and this is the table used by the system to run the different functions included in it.

There is an "ACTIVE TABLE" setting that determines the settings table that is active at a given moment.

The active settings table can be changed by means of up to 2 digital inputs, referred to as "ACTIVE TABLE SELECT 0" and "ACTIVE TABLE SELECT 1" which allow up to 4 combinations from 0 to 3. To do this it is necessary to configure (using GE-INTRO software) two inputs to have these meanings. For applications which require less tables (up to 2) it is possible to use only one input.

The selected combination is obtained from the binary coding of the 2 inputs mentioned (see following table). The 0-0 means selecting the table indicated in the "ACTIVE TABLE" setting, and numbers 0-1 to 1-1 select tables 1 to 3 respectively

Table Selection	Table Selection	Active Table
INPUT-1	INPUT-0
0	0	Selected by setting
0	1	1
1	0	2
1	1	3

NOTE: if the inputs are programmed and used, energizing them, this selection has priority over the "ACTIVE TABLE" setting and the table which is in fact used is determined by the status of the digital inputs.
