6.10.2 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
122 DTT Direct Trip = Enabled was applied. In address 2201 DTT Di-
rect Trip ON
or OFF, 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
theremotetripinaddress
2202 Trip Time DELAY. 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
TMin TRIP CMD, 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.
