To Block a Complete Protection Module Temporarily by an Active Assignment
In order to establish a temporary blockage of a protection module, the parameter »ExBlo Fc« of the module has
to be set to »Active« . This gives the permission: »This module can be blocked«.
Within the general protection parameters, a signal has to be additionally chosen from the »Assignment list«.
The blocking only becomes active when the assigned signal is active.
To Block the Tripping Command of a Protection Element Temporarily by an Active Assignment
The tripping command of any of the protection modules can be blocked from an external signal. In this case, external
does not only mean from outside the device, but also from outside the module. Not only real external signals are
permitted to be used as blocking signals (for example: the state of a digital input), but the User can also choose any
other signal from the »Assignment list«.
In order to establish a temporary blockage of a protection element, the parameter »ExBlo TripCmd Fc« of the
module has to be set to »Active« . This gives the permission: »The tripping command of this element can be
blocked«.
Within the general protection parameters, an additional signal has to be chosen and assigned to the »ExBlo«
parameter from the »Assignment list«. If the selected signal is activated, the temporary blockage becomes
effective.
