12.2.2.10 ARMode = 1/2ph, 1-phase or 2-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 auto reclosing can
follow, if selected. In the event of a three-pole trip, TR3P input high, the auto recloser will be inhibited and
no auto reclosing takes place.
12.2.2.11 ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shot
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".
12.2.2.12 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".
12.2.2.13 ARMode = 1ph + 1*2/3ph, 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 above described example, 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 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".
