At address  =21( 6(4&225', the zone sequencing feature can be turned 21
or 2)). If zone sequencing is turned on, then the device counts the number of reclos-
ing attempts made by sequenced devices via flow measurement so that tripping can
be blocked for based on the reclosing attempt of another device.
At addresses  to , reclosing can be initiated or blocked for various types of
protective elements.
At addresses  to , it is possible to block tripping by various types of protec-
tive elements subsequent to any of the first four reclosing attempts. The settings in
these addresses are used when zone sequencing is turned on and if the protection of
load side fuses against temporary fault is desired. Zone sequencing is enabled in ad-
dress .
