While any of the auto-reclosing open time timers are running, the output INPROGR is activated.When the "open reset" timer runs out, the respective internal signal is transmitted to the outputmodule for further checks and to issue a closing command to the circuit breaker.When a CB closing command is issued the output prepare 3-pole trip is set. When issuing a CBclosing command a “reset” timertReset is started. If no tripping takes place during that time theauto-reclosing function resets to the “Ready” state and the signal ACTIVE resets. If the firstreclosing shot fails, a 3-pole trip will be initiated and 3-phase reclosing can follow, if selected.13.2.2.10ARMode=1/2ph, 1-phase or 2-phase reclosing in the first shot. M12391-136 v4In 1-pole or 2-pole tripping, the operation is as in the above described example, program mode1/2/3ph. If the first reclosing shot fails, a 3-pole trip will be issued and 3-phase reclosing canfollow, if selected. In the event of a 3-pole trip, TR3P high, the auto-reclosing will be blocked and noreclosing takes place.13.2.2.11ARMode=1ph + 1*2ph, 1-phase or 2-phase reclosing in the first shot M12391-139 v4The 1-phase reclosing attempt can be followed by 3-phase reclosing, if selected. A failure of a 2-phase reclosing attempt will block the auto-reclosing. If the first trip is a 3-pole trip the auto-reclosing will be blocked. In the event of a 1-pole trip, (TR2P low and TR3P low), the operation is asin the example described above, program mode1/2/3ph. If the first reclosing shot fails, a 3-poletrip will be initiated and 3-phase reclosing can follow, if selected. A maximum of four additionalshots can be done (according to theNoOfShots parameter). At 2-pole trip (TR2P high and TR3Plow), the operation is similar to the above. But, if the first reclosing shot fails, a 3-pole trip will beissued and the auto-reclosing will be blocked. No more shots are attempted! The expression1*2phshould be understood as “Just one shot at 2-phase reclosing” During 3-pole trip (TR2P low andTR3P high) the auto-reclosing will be blocked and no reclosing takes place.13.2.2.12 ARMode=1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing in the firstshot GUID-9C2FB801-F324-465E-8FD2-715A9C3D0BD8 v1At 1-phase or 2-phase trip, the operation is as described above. If the first reclosing shot fails, a 3-phase trip will be issued and 3-phase reclosing will follow, if selected. At 3-phase trip, theoperation is similar to the above. But, if the first reclosing shot fails, a 3-phase trip command willbe issued and the auto-reclosing will be blocked. No more shots take place! 1*3ph should beunderstood as “Just one shot at 3-phase reclosing”.13.2.2.13ARMode=1ph + 1*2/3ph, 1-phase, 2-phase or 3-phase reclosing in the firstshot M12391-146 v4At 1-pole trip, the operation is as described above. If the first reclosing shot fails, a 3-pole trip willbe issued and 3-phase reclosing will follow, if selected. At 2-pole or 3-pole trip, the operation issimilar as above. But, if the first reclosing shot fails, a 3-pole trip will be issued and the auto-reclosing will be blocked. No more shots take place! “1*2/3ph” should be understood as “Just oneshot at 2-phase or 3-phase reclosing”.Section 13 1MRK 511 358-UUS AControl276Application manual
