Section 14
Control
When a circuit breaker closing command is issued, the prepare three-pole output trip is set. When
issuing a circuit breaker closing command the
during that time, the auto recloser resets to the "Ready" state and the
first reclosing shot fails, a three-phase trip will be initiated and three-phase reclosing can follow, if
selected.
ARMode = 1/2ph , 1-phase or 2-phase reclosing in the first shot
14.2.2.10
At single-pole or two-pole tripping, the operation is as in the example described above, program
1/2/3ph . If the first reclosing shot fails, a three-pole trip will be issued and three-pole auto
mode
reclosing can follow, if selected. In the event of a three-pole trip,
will be inhibited and no auto reclosing takes place.
ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shot
14.2.2.11
At single-pole tripping, the operation is as in the above described example, program mode
1/2/3ph . The single-pole auto reclosing attempt can be followed by three-pole reclosing, if
selected. At two-pole trip, a failure of a two-pole auto reclosing attempt will inhibit the auto
recloser. No more shots are attempted. If the first trip is a three-pole trip, the auto-reclosing will
be inhibited. No more shots are attempted. The expression "1*2ph" should be understood as "Only
one shot at two-phase auto reclosing".
14.2.2.12 ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in the first
shot
At single-pole or two-pole tripping, the operation is as in the example described above, program
mode 1/2/3ph . If the first reclosing shot fails, a three-pole trip will be issued and three-pole
reclosing will follow, if selected. At three-pole trip, a failure of a three-pole auto reclosing attempt
will inhibit the auto recloser. No more shots are attempted. The expression "1*3ph" should be
understood as "Only one shot at three-pole auto reclosing".
ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in the first
14.2.2.13
shot
At single-pole or two-pole tripping, the operation is as in the above described example, program
1/2/3ph . If the first reclosing shot fails, a three-pole trip will be issued and three-pole
mode
reclosing will follow, if selected. At two-pole or three-pole trip a failure of a two-pole or three-pole
auto reclosing attempt will inhibit the auto recloser. No more shots are attempted. The expression
"1*2/3ph" should be understood as "Only one shot at two-pole or three-pole auto reclosing".
