MODEINT (integer)
A start of a new auto reclosing cycle during the set "reset time" is blocked when the set number of
reclosing shots have been reached.

External selection of auto reclosing mode
The auto reclosing mode can be selected by use of available logic function blocks. Below is an example
where the choice of mode, ARMode=3ph or ARMode=1/2/3ph, is done from a hardware function key at
the front of the IED, 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 reclosing mode is shown in Figure 133.

Auto reclosing reset timer
The tReset timer defines the time it takes from issue of the breaker closing command, until the auto
recloser 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 circuit breaker closing command is given.
12.2.2.16
Pulsing of the circuit breaker closing command and counter
The circuit breaker closing command, CLOSECB is given as a pulse with a duration set by the tPulse
setting. For circuit breakers without an anti-pumping function, close pulse cutting can be used. It is
selected by the CutPulse setting. In case of a new start pulse (trip), the breaker closing command pulse
is then cut (interrupted). The minimum breaker closing command pulse length is always 50ms. At the
issue of the breaker closing command, the appropriate auto recloser operation counter is incremented.
