Technical description

Output relay matrix

By means of the relay matrix the output signals of the various
protection stages can be combined with the trip relay T1 and
T2, alarm relays A1...A3 and the operation indicator L1
(Alarm) and L2 (Trip).
When a connection is made, two functions can be selected, the
signal follower function (•) or the latching function (o), see
Figure 2.4-1.
The "Reset all latches" function resets all latched output relays
and operation indicators. The reset signal can be given via a
digital input, the key pad or the serial port. If the reset signal
is to be given via the digital input DI1, the Remote Release
("RemRel") input DI1 must be configured to function as a reset
input from DIGITAL IN/RemRel menu.

Blocking matrix

By means of the block matrix the operation of a protection
stage can be blocked. During blocking, a stage will not start or
if already started the delay counter is halted, thus preventing
tripping. The blocking signal can originate from the digital
input DI1, or it can be a start or trip signal from a protection
stage. In Figure 2.4-1, a blocking connection is indicated with a
black dot ( • ) in the crossing point of a blocking signal and a
signal to be blocked.

Communication

PC port

The PC port is used for on-site parameterization of the relay,
for downloading of the program and for reading relay
parameters to a PC.
For connection to a PC, one RS 232 serial port is available on
the front panel of the relay. Any connection to the port is done
with the connection cable type VX 003.
