I don't understand the address 1357 1st AR -> Z1B. ¿It´s only for a external autoreclose or It´s for the internal autoreclose. too? "If the distance protection is used in conjunction with an external automatic recloser, it can be determined in address13571st AR -> Z1Bwhich distance zone is released prior to starting the AR. Usually, the overreaching zone Z1B is used for the first cycle (1st AR -> Z1B=YES). This may be suppressed by changing the setting of1st AR -> Z1BtoNO. In this case, the overreaching zone Z1B is not released before and during the first automatic reclose cycle. Zone Z1 is always released. When using an external automatic reclosing device, the setting only has an effect if the readiness of the automatic recloser is signalled via binary input">Enable ARzones"(No.383)."
