Global Protection Parameters of the Zone Interlocking
In the global parameter menu for zone interlocking, two external blocking inputs (»
Ex Block1/Ex Block2«), as with other
protection modules, can be assigned to the input of the zone interlocking function so that the zone interlock function can
be blocked by an assigned function.
Via an external input signal, the zone interlocking can also be blocked if the parameter »
ExtBlockTripCMD« is assigned.
Breaker Failure Pickup flag BF.Pickup is implicitly connected to zone
interlocking, so that NO zone interlock output signal can be sent to the
upstream device if a breaker failure on downstream device is detected.
