14.5.4 Functionality Enabling
The Functionality Enabling checklist manages the enabling of a number of automation functions.
The SW enabling of the automation function is only one of the possible conditions to be verified to
operate the automation. Additional necessary conditions may be activation of a specific digital input
(DI) and a specific HW setting on the IED. Tick the following for each function whose conditions apply.
Close Command
Open Command
Circuit-Breaker Status
Toc
All automation functions are not ticked (i.e. inactive) by default. In the example (figure above) the
UnderVoltage function is enabled.
14.5.5.1 ANSI Re-close
This activates the Re-Close Function according to ANSI requirements, see figure.
This function is only activated when the CB is in the closed position and a Close Command is valid
(positive edge event). Close and Open can be local or remote commands. If the close command is
released (negative edge) before the open command (positive edge event), the function is a normal
open command and the re-close function will not be performed. If the close command is released
any time after the open command positive edge, the re-close function is correctly performed.
