5.3.3 Functionality
The master trip function TRPPTRC is used as a trip command collector and handler
after the protection functions. The features of this function influence the trip signal
behavior of the circuit breaker. The minimum trip pulse length can be set when the
non-latched mode is selected. It is also possible to select the latched or lockout
mode for the trip signal.
5.3.4 Operation principle
The function can be enabled and disabled with the
Operation setting. The
corresponding parameter values are "On" and "Off".
When the TRPPTRC function is disabled, all trip outputs intended to go
through the function to the circuit breaker trip coil are blocked.
The operation of TRPPTRC can be described with a module diagram. All the modules
in the diagram are explained in the next sections.
