A start of a new reclosing cycle is blocked during the set “reclaim time” after the selected
number of reclosing shots have been made.
13.2.2.14 External selection of auto-reclose mode
M12391-241 v3
The auto-reclose mode can be selected by use of the available logic function blocks. Below is
an example where the choice of mode is done from a hardware function key in front of the IED
with only 3 phase or 1/3 phase mode, but alternatively there can for example, be a physical
selector switch on the front of the panel which is connected to a binary to integer function
block (BTIGAPC).
The connection example for selection of the auto-reclose mode is shown in
Figure.

13.2.2.15 Reclosing reclaim timer
M12391-202 v3
The reclaim timer
tReclaim
defines the time it takes from issue of the reclosing command,
until the reclosing function resets. Should a new trip occur during this time, it is treated as a
continuation of the first fault. The reclaim timer is started when the CB closing command is
given.
