• If inputs TR2P is low and TR3P is low (1-pole trip): The timer for 1-phase reclosing
open time is started and the output 1PT1 (1-phase reclosing in progress) is activated.
It can be used to suppress pole disagreement and ground-fault protection trip during
the 1-phase open interval.
• If TR2P is high and TR3P is low (2-pole trip): The timer for 2-phase reclosing open
time is started and the output 2PT1 (2-phase reclosing in progress) is activated.
• If TR3P is high (3-pole trip): The timer for 3-phase auto-reclosing open time, t1 3Ph
is started and output 3PT1 (3-phase auto-reclosing shot 1 in progress) is set.
• If STARTHS is high (3-phase trip): The timer for 3-phase auto-reclosing open time,
t1 3PhHS is started and output 3PT1 (3-phase auto-reclosing shot 1 in progress) is set.
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 output module 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 CB closing command a "reset" timer tReset is started. If no tripping takes place during
that time the auto-reclosing function resets to the "Ready" state and the signal ACTIVE
resets. If the first reclosing shot fails, a 3-pole trip will be initiated and 3-phase reclosing
can follow, if selected.

ARMode = 1/2ph , 1-phase or 2-phase reclosing in the first shot.

In 1-pole or 2-pole tripping, the operation is as in the above described example, program
mode 1/2/3ph. If the first reclosing shot fails, a 3-pole trip will be issued and 3-phase
reclosing can follow, if selected. In the event of a 3-pole trip, TR3P high, the auto-
reclosing will be blocked and no reclosing takes place.

ARMode =1ph + 1*2ph, 1-phase or 2-phase reclosing in the first shot

The 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 as in the example described above, program mode 1/2/3ph. If the first
reclosing shot fails, a 3-pole trip will be initiated and 3-phase reclosing can follow, if
selected. A maximum of four additional shots can be done (according to the NoOfShots
parameter). At 2-pole trip (TR2P high and TR3P low), the operation is similar to the
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 are attempted! The expression 1*2ph should be
understood as "Just one shot at 2-phase reclosing" During 3-pole trip (TR2P low and
TR3P high) the auto-reclosing will be blocked and no reclosing takes place.
