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«.
