6.8.2 Applying the Function Parameter Settings
A prerequisite for the application of the direct and remote tripping functions is that dur-
ing the configuration of the scope of functions in the device (Section 5.1) the setting in
address  '77'LUHFW7ULS = (QDEOHG was applied. In address  '77
'LUHFW7ULS 21 or 2)), it is furthermore possible to switch the function on or off.
It is possible to set a trip delay for both the local external trip and the receive side of
the remote trip in address  7ULS7LPH'(/$<. This can be used as a security
time margin, especially in the case of local trip.
Once a trip command has been issued, it is maintained for at least as long as the set
minimum trip command duration 70LQ75,3&0', which was set for the device in
general in address 240A (Sub-section 6.1.1). Reliable operation of the circuit breaker
is therefore ensured, even if the initiating signal pulse is very short.
