Trip Commands
While trip signals issued by the CB failure protection have no timer stages
available the user can set minimum time delays for trip commands.
By appropriate setting it can further be determined that trip commands, issued
by the CB failure protection, will operate in latching mode. The respective trip
command, set to latch mode, will remain active until reset by operating
parameters or through an appropriately configured binary signal input.

Starting Trigger
Should a downstream CB fail, a trip can be issued by the CB failure protection
function. In this case the dedicated general interrogation is checked as a
condition so as to guarantee increased security against overreaction.
The signal CBF_1: Starting will be issued when the signal CBF_1: Starting
trig. EXT is presented to an appropriately configured binary signal input and a
general starting is present. The signal CBF_1: Trip signal will be issued after
timer stage CBF_1: Delay/starting trig. has elapsed.
