expression “1*2ph” should be understood as “Only one shot at two-phase autoreclosing”.12.2.2.12 ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in thefirst shot GUID-9C2FB801-F324-465E-8FD2-715A9C3D0BD8 v2At 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 issuedand 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 autoreclosing”.12.2.2.13ARMode = 1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in thefirst shot M12391-146 v5At 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 issuedand three-pole reclosing will follow, if selected. At two-pole or three-pole trip a failureof a two-pole or three-pole auto reclosing attempt will inhibit the auto recloser. Nomore shots are attempted. The expression “1*2/3ph” should be understood as “Onlyone shot at two-pole or three-pole auto reclosing”.Table 38:Type of reclosing shots at different settings of ARMode or integer inputs to MODEINTMODEINT (integer) ARMode Type of fault 1st shot 2nd-5th shot1 3ph1ph 3ph 3ph2ph 3ph 3ph3ph 3ph 3ph2 1/2/3ph1ph 1ph 3ph2ph 2ph 3ph3ph 3ph 3ph3 1/2ph1ph 1ph 3ph2ph 2ph 3ph3ph ..... .....4 1ph + 1*2ph1ph 1ph 3ph2ph 2ph .....3ph ..... .....5 1/2ph + 1*3ph1ph 1ph 3ph2ph 2ph 3ph3ph 3ph .....Table continues on next pageSection 12 1MRK 505 370-UUS AControl322 Busbar protection REB670 2.2 ANSIApplication manual
