IM02602003E
Blocking
The device provides a function for temporary blocking of the complete protection functionality or of single protections.
Make absolutely sure that no illogical or even life-threatening blockings are
allocated.
Make sure not to carelessly deactivate protection functions that have to be
available according to the protection concept.
Permanent Blocking
Switching “On” or “Off” the Complete Protection Functionality
In the
»Protection« module, the complete protection of the device can be switched “On” or “Off”. Set the Function
parameter to
»Active« or »Inactive« in the
»Prot«
module
.
Protection is activated only if in the »Prot« module the parameter
Function is =
»Active« (i.e.: with »Function« = »Inactive«, no protection function are
operating). If
»Function« = »Inactive«, then the device cannot protect any
components.
Switching Modules “On” or “Off”
Each of the modules can be switched “On” or “Off” (permanently). This is achieved when the »
Function« parameter is
set to »Active« or
»I
nactive« in the respective module.
Activating or Deactivating the Tripping Command of a Protection Permanently
In each of the protections, the tripping command to the breaker can be permanently blocked. For this purpose, the
»TripCmd Blo« parameter has to be set to »Active«.
Temporary Blocking
To Block the Complete Protection of the Device Temporarily by a Signal
In the
»Prot« module, the complete protection of the device can be blocked temporarily by a signal. On the condition
that a module-external blocking is permitted (
»ExBlo Fc=active«). In addition to this, a related blocking signal from the
»Assignment list« must have been assigned. For the time the allocated blocking signal is active, the module is blocked.
If the
»Prot« module is blocked, the complete protection function does not work.
As long as the blocking signal is active, the device cannot protect any
components.
