2.5.2.
Local/Remote selection
In Local mode, the output relays can be controlled via a local
HMI, but they cannot be controlled via a remote serial
communication interface.
In Remote mode, the output relays cannot be controlled via a
local HMI, but they can be controlled via a remote serial
communication interface.
The selection of the Local/Remote mode is done by using a local
HMI, or via one selectable digital input. The digital input is
normally used to change a whole station to a local or remote
mode. The selection of the L/R digital input is done in the
“Objects” menu of the VAMPSET software.
NOTE!
A password is not required for a remote control operation.
2.5.3.
Logic functions
The manager supports customer-defined logics. The logics are
designed by using the VAMPSET setting tool and downloaded
to the manager. For detailed information, please refer to the
VAMPSET manual (VMV.EN0xx).

Blocking and output relay functions
All the start and trip signals of the protection stages can be
freely routed to the output relays and operation indicators
according to the requirements of the application. The functions
can also be blocked, and for this purpose both internal relay
signals and external control signals can be used. Figure shows
the operating principle of the output and blocking matrixes.
