more shots are attempted. The expression “1*3ph” should be understood as “Only
one shot at three-phase auto reclosing”.
15.2.2.13
ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in
the first shot
M12391-146 v5
At single-phase or two-phase tripping, the operation is as in the above described
example, program mode 1/2/3ph. If the first reclosing shot fails, a three-phase trip
will be issued and three-phase reclosing will follow, if selected. At two-phase or
three-phase trip a failure of a two-phase or three-phase 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-phase or three-phase auto
reclosing”.

A start of a new auto reclosing cycle during the set “reclaim time” is blocked when
the set number of reclosing shots have been reached.

The auto reclosing mode can be selected by use of available logic function blocks.
