2.6.1.
Blocking matrix
By means of a blocking matrix (Block matrix), the operation of
protection stage can be blocked. The blocking signal can
originate from the digital inputs DI1 to DI32, or it can be a
start or trip signal from a protection stage. Furthermore, the
logic functions can be used to develop a blocking signal. In
Figure, an active blocking is indicated with a black dot (•) in
the crossing point of a blocking signal and the signal to be
blocked.
NOTE!
The blocking matrix is available for configuration only in the
VAMPSET software.
2.6.2.
Output matrix
By means of an output matrix, the output signals of the various
protection stages can be combined with the trip relays T1 to T8,
the alarm relays from A1 to A5 and the operation indicators Al
(Alarm led) and Tr (Trip led).
Furthermore, there are three leds (A, B and C) available for
customer-specific indications. In addition, the triggering of the
disturbance recorder (Dr) is configured in the output matrix.
When the signals are combined, two functions can be selected:
the signal follower function (o) or the latching function (•), see
Figure.
The reset signal resets all the latched output relays and
operation indicators. The reset signal can be given via a digital
input, via a keypad or through communication. Any digital
input can be used for resetting. The selection of the input (from
DI1 to DI32) is done with the VAMPSET software under the
menu “Release output matrix latches”. Under the same menu,
the “Release latches” parameter can be used for resetting. The
remote communication protocols use “RemRel” signal for
resetting purposes.
2.6.3.
Virtual inputs and outputs
Virtual inputs acts like normal digital inputs. The state of the
virtual input can be changed from display, communication bus
and from VAMPSET. For example setting groups can be change
via virtual inputs.
Virtual outputs act like output relays. Virtual outputs are
shown in blocking and output matrixes. Virtual outputs can
also change the active setting group.
