international standards.
STOP
Safety Earth Ground
This is a Safety Class 1 product (a
protective earth terminal is provided).
An uninterrupted safety earth ground
must be provided from the main power
source to the product input wiring
terminals, power cord, or supplied
power cord set.
Whenever it is likely that the protection
has been impaired, the product must be
made inoperative and secured against
any unintended operation.

Functional description
The tripping matrix
GKV 10x40 621 SK R EEaLDPa
is a component of a generator protec-
tion system. The tripping matrix provi-
des a transparent, easily programmable
facility for combining output commands
of the trip outputs of individual protec-
tion devices with plant items such as
the circuitbreakers, de-excitation etc.
The matrix was developed for mar-
shalling tripping commands of large po-
wer stations. With its help, the tripping
schematic can be temporarily changed,
e.g. in case of a generator circuit-brea-
ker revision. If the software matrix
incorporated in each generator
protection unit is used for marshalling
the tripping commands, the marshalling
in the protection units must be changed
for this purpose.
The tripping matrix assigns the tripping
signals arriving at the matrix columns
(from the solid-state protection relays)
to the freely programmable matrix lines
to which the tripping modules are
connected.
Mode of Operation
The tripping matrix GKV 10x40 621
SK R EEaLDPa has 40 columns (for 40
signals from protection units) and 10
rows (for 10 signals to tripping
modules)
Each of the 40 column signals may be
connected twice by tap connectors.
High reliability diode plugs (black
handle) are used for programming the
matrix, the reliability being attained by
generous over-rating with respect to
forward current and reverse voltage.
The diode plugs are inserted from the
front and enable any vertical column
(signals from the protection relays) to
be connected to any horizontal line so
that the tripping signals can be
transmitted to the tripping module.
Each column has a LED for indicating
tripping commands. The display is
stored.
Each additional incoming tripping
command received additionally sets a
group memory, which, can be used for
remote signalling and switching a rack
lamp.
All signals remain stored even when
the tripping channels are interrupted or
when the red central connecting plug is
removed.
The memories can be reset directly by
a push-button "Reset" or by remote
reset.
The function of all LED’s may be
checked by pressing the "LED-Test"
button.
The power supply of the relays and
memory functions is 250VDC and feed
an additional 5 VDC voltage for the LED
function. The monitoring of the power
supply is done by two relay contacts.
A lockable plexi-cover inhibits
unauthorised access to the program-
ming matrix.
Unused diodes and connecting plugs are
stored in a pin park.
