Blockings
Blockings
The device provides a function for temporary and permanent blocking of the complete protection functionality or of
single protection stages.
Make absolutely sure that no illogical or even life-threatening blockings are
allocated.
Make sure that you do not carelessly deactivate protection functions which
have to be available according to the protection concept.
Permanent Blocking
Switching ON or OFF the complete protection functionality
In module
»Protection« the complete protection of the device can be switched on or off. Set the parameter Function
to
»active« or »inactive« in module
»Prot«.
Only if in module »Prot« the parameter
»Function« is = »active«, the
protection is activated; i.e. with
»Function« = »inactive«, no protection
function is operating. 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 parameter »
Function« is
set to »active« or
»
inactive« in the respective module.
Activating or deactivating the tripping command of a protection stage permanently
In each of the protection stages the tripping command to the CB can be permanently blocked. For this purpose the
parameter
»TripCmd Blo« has to be set to »active«.
