1.2. User interface
The relay can be controlled in three ways:
Locally with the push-buttons on the relay front panel
Locally using a PC connected to the serial port on the front
panel or on the rear panel of the relay (both cannot be used
simultaneously)
Via remote control over the remote control port on the relay
rear panel.
1.3. Operating Safety
The terminals on the rear panel of the relay may
carry dangerous voltages, even if the auxiliary
voltage is switched off. A live current transformer
secondary circuit must not be opened.
Disconnecting a live circuit may cause dangerous
voltages! Any operational measures must be carried
out according to national and local handling
directives and instructions.
Carefully read through all operation instructions before any
operational measures are carried out.

2.2.3. Setting groups
Most of the protection functions of the relay have two setting
groups. These groups are useful for example when the network
topology is changed frequently. The active group can be
changed by a digital input, through remote communication or
locally by using the local panel.
The active setting group of each protection function can be
selected separately. Figure 2.2.3-1 shows an example where the
changing of the I> setting group is handled with digital input
one (SGrpDI). If the digital input is TRUE, the active setting
group is group two and correspondingly, the active group is
group one, if the digital input is FALSE. If no digital input is
selected (SGrpDI = -), the active group can be selected by
changing the value of the parameter SetGrp.
Figure 2.2.3-1. Example of protection submenu with setting group
parameters
The changing of the setting parameters can be done easily.
When the desired submenu has been found (with the arrow
keys), press the ENTER key to select the submenu. Now the
selected setting group is indicated in the down-left corner of the
display (See Figure 2.2.3-2). Set1 is setting group one and Set2
is setting group two. When the needed changes, to the selected
setting group, have been done, press the LEFT or the RIGHT
key to select another group (the LEFT key is used when the
active setting group is 2 and the RIGHT key is used when the
active setting group is 1).

2.2.4. Fault logs
All the protection functions include fault logs. The fault log of a
function can register up to eight different faults with time
stamp information, fault values etc. Each function has its own
logs (See Figure 2.2.4-1).
Figure 2.2.4-1. Example of fault log
To see the values of, for example, log two, press the ENTER key
to select the current log (log one). The current log number is
then indicated in the down-left corner of the display (See
