What is the definition of ANSI 86 - Latching / acknowledgement?

The tripping outputs for all the protection functions and all the logic inputs can be
latched individually. The latched information is saved in the event of an auxiliary
power failure.
(The logic outputs cannot be latched.)
All the latched data may be acknowledged:
  • locally, with the key
  • remotely via a logic input
  • or via the communication link.
The Latching/acknowledgement function, when combined with the circuit breaker/
contactor control function, can be used to create the ANSI 86 “Lockout relay”
function.
