Technical Manual
Blocking logic
The binary input BLOCK can be used to block the function. The activation of the BLOCK
input deactivates RELEASE output and resets the Timer.
4.4.2.5
Application
The directional negative/zero sequence power protection (32N) function improves the
possibility to obtain selective function of the over-current protection in meshed networks.
The 32N function is used to block or release other over current protection function.
