2.4.1.
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...A5 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" signal resets all latched output relays
and operation indicators. The reset signal can be given via a
digital input, the keypad or the serial port. If the reset signal is
to be given via one of the digital inputs DI1...DI6, the Remote
Release (“RemRel”) input must be configured for that purpose.
2.4.2.
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
inputs DI1…DI6, or it can be a start or trip signal from a
protection stage. In Figure 2.4-1 blocking connection is
indicated with a black dot (•) in the crossing point of a blocking
signal and a signal to be blocked.

Communication
2.5.1.
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.
2.5.2.
Remote control connection
The relay can be connected to higher level systems, e.g.
network control systems via the serial port named REMOTE on
the rear panel. To the port a SPA-Bus, ModBus, ProfiBus or
IEC-103 connection can be made using a special internal or
external bus connection module. The bus type selection and the
parameterization of the bus are carried out as the relay is
configured.
