disagreement and earth-fault protection trip during the single-phase dead timeinterval..• If TR2P input is high and TR3P input is low (i.e. two-phase trip): The timer fortwo-phase auto reclosing dead time is started and the 2PT1 output (two-phasereclosing in progress) is activated.• If TR3P input is high (i.e. three-phase trip): The timer for three-phase autoreclosing dead time, t1 3Ph or t1 3PhHS, is started depending on if START orSTARTHS input has been activated and 3PT1 output (three-phase reclosingshot 1 in progress) is set..While any of the auto reclosing dead time timers are running, the INPROGR outputis activated. When the dead time runs out, the respective internal signal istransmitted to the output module for further checks and to issue a breaker closingcommand.When a circuit breaker closing command is issued, the prepare three-phase outputtrip is set. When issuing a circuit breaker closing command the tReclaim timer isstarted. If no tripping takes place during that time, the auto recloser resets to the“Ready” state and the ACTIVE output resets. If the first reclosing shot fails, a three-phase trip will be initiated and three-phase reclosing can follow, if selected.15.2.2.10ARMode =1/2ph, 1-phase or 2-phase reclosing in the first shot M12391-136 v5At single-phase or two-phase tripping, the operation is as in the example describedabove, program mode 1/2/3ph. If the first reclosing shot fails, a three-phase tripwill be issued and three-phase auto reclosing can follow, if selected. In the event ofa three-phase trip, TR3P input high, the auto recloser will be inhibited and no autoreclosing takes place.15.2.2.11ARMode = 1ph+1*2ph, 1-phase or 2-phase reclosing in the first shotM12391-139 v5At single-phase tripping, the operation is as in the above described example,program mode 1/2/3ph. The single-phase auto reclosing attempt can be followed bythree-phase reclosing, if selected. At two-phase trip, a failure of a two-phase autoreclosing attempt will inhibit the auto recloser. No more shots are attempted. If thefirst trip is a three-phase trip, the auto-reclosing will be inhibited. No more shotsare attempted. The expression “1*2ph” should be understood as “Only one shot attwo-phase auto reclosing”.15.2.2.12 ARMode = 1/2ph + 1*3ph, 1-phase, 2-phase or 3-phase reclosing inthe first shot GUID-9C2FB801-F324-465E-8FD2-715A9C3D0BD8 v2At single-phase or two-phase tripping, the operation is as in the example describedabove, program mode 1/2/3ph. If the first reclosing shot fails, a three-phase tripwill be issued and three-phase reclosing will follow, if selected. At three-phase trip,a failure of a three-phase auto reclosing attempt will inhibit the auto recloser.
