14. Fuse failure supervision

Depending on the chosen standard configuration, the relay
includes fuse failure supervision functionality. The fuse failure
supervision detects failures between the voltage measurement
circuit and the relay. The failures are detected either by the
negative sequence-based algorithm or by the delta voltage and
delta current algorithm. Upon the detection of a failure, the fuse
failure supervision function activates an alarm and blocks
voltage-dependent protection functions from unintended
operation.

15. Access control

To protect the relay from unauthorized access and to maintain
information integrity, the relay is provided with a four-level, role-
based authentication system with administrator-programmable
individual passwords for the viewer, operator, engineer and
administrator levels. The access control applies to the local
HMI, the Web HMI and PCM600.

16. Inputs and outputs

The relay is equipped with six phase-current inputs and one
neutral-current input or six phase-current inputs, one neutral-
current input, three phase-voltage inputs and one residual
voltage input. The rated level of the current inputs is 1/5 A and
selectable in the relay software. The three phase-voltage inputs
and the residual-voltage input covers the rated voltages 60...

17. Station communication

The relay supports a range of communication protocols
including IEC 61850 Edition 2, IEC 61850-9-2 LE, IEC

210 V. Both phase-to-phase voltages and phase-to-earth
voltages can be connected. In addition, the binary input
thresholds 16...176 V DC are selected by adjusting the relay's
parameter settings.
All binary input and output contacts are freely configurable with
the signal matrix or application configuration functionality of
PCM600.
As an option for standard configurations A, B, C and D, the relay
offers six RTD inputs and two mA inputs. By means of the
optional RTD/mA module the relay can measure up to eight
analog signals such as temperature, pressure and tap changer
position values via the six RTD inputs or the two mA inputs
using transducers. The values can, apart from measuring and
monitoring purposes, be used for tripping and alarm purposes
using the offered optional multipurpose protection functions.
As an option for standard configurations E, F, G and H, the relay
offers two RTD inputs and one mA input.
As an option a binary input and output module can be selected,
having three high speed binary outputs (HSO), decreasing
further the total operate time with typically 4...6 ms compared
to the normal power outputs.
See the Input/output overview table and the terminal diagrams
for more information about the inputs and outputs.

are available through these protocols. However, some
communication functionality, for example, horizontal
communication between the relays, is only enabled by the IEC
61850 communication protocol.
The IEC 61850 protocol is a core part of the relay as the
protection and control application is fully based on standard
