SEL-351P Manual Técnico
The EZ recloser control settings for a given setting group n override and change a number of the
“regular” settings in the same setting group n (set with the SET n command, in Access Level 2) if
the group number n is encompassed by the global setting EZGRPS (set with the SET G
command, in Access Level 2) – see Table 1.1. Global setting EZGRPS enables the EZ settings in
the encompassed settings groups.
For example, if EZGRPS = 2 (the factory setting), then you can make EZ recloser control settings
for settings groups 1 (main settings) and 2 (alternate settings) with the SET EZ 1 and SET EZ 2
commands, respectively. The EZ recloser control settings for settings groups 1 and 2 also
override a number of the “regular” settings in the respective setting group. If EZGRPS = 2, the
EZ settings for settings groups 3 through 6 cannot be made, nor are the EZ settings for settings
groups 3 through 6 active (none of the “regular” settings in settings groups 3 through 6 are
overridden).
The SET FZ command allows you to change the EZ global settings. The EZ global settings also
override a number of the “regular” global settings (set with the SET G command, in Access
Level 2) if global setting EZGRPS > 0 – see end of Table 1.1.
Access Level B Commands
Access Level B commands primarily allow you to operate control parameters and output contacts
without allowing you access to change settings. All Access Level 1 and Access Level E
commands can also be executed from Access Level B. The screen prompt is: ==>
BRE n Command (Preload/Reset Breaker Wear)
Use the BRE W A command to preload breaker/recloser contact wear and trip operation
counters. For example, to preload the breaker/recloser wear to 25%, 28%, and 24% for the
respective phases and preload some trip operation counters, issue the command below.
==>BRE W A <ENTER>
Breaker Wear Percent Preload
A-phase % = 4 ? 8 <ENTER>
B-phase % = 4 ? 7 <ENTER>
C-phase % = 6 ? 10 <ENTER>
Trip Counter Preload
Ext Trips= 3 ?
Cntrl Trips= 9 ? 16
A-phase Trips= 6 ? 14
B-phase Trips= 5 ? 9
C-phase Trips= 8 ? 10
EF/G Trips= 7 ? 12
SEF Trips= 0 ?
Are you sure (Y/N) ? Y <ENTER>
