Functionality
The master trip function 86/94 is intended to be 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 “Enable” and “Disable”.
When the 86/94 function is disabled, all trip outputs which are intended to
go through the function to the circuit breaker trip coil are blocked.
The operation of 86/94 can be described with a module diagram. All the modules in the
diagram are explained in the next sections.
