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.

!

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.

2. After any selection, the arrow symbols in the upper left

corner of the display show the possible navigating directions
(applicable navigation keys) in the menu.

3. The name of the active submenu and a possible ANSI code

of the selected function are shown in the upper part of the
display, e.g. CURRENTS.

4. Further, each display holds the measured values and units

of one or more quantities or parameters, e.g. Ilmax 300A.

2.1.3. Keypad

You can navigate in the menu and set the required parameter
values using the keypad and the guidance given in the display.
Furthermore, the keypad is used to control objects and switches
on the single line diagram display. The keypad is composed of
four arrow keys, one cancel key, one enter key and one info key.

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
Figure 2.2.4-2, Log2 = log two). The log two is selected by
pressing the RIGHT key once.

Opening access

1. Push the INFO key and the ENTER key on the front panel.

Figure 2.2.5-1. Opening the access level

2. Enter the password needed for the desired level: the

password can contain four digits. The digits are supplied
one by one by first moving to the position of the digit using
the RIGHT key and then setting the desired digit value
using the UP key.

3. Push the ENTER key.

Password handling

The passwords can only be changed using VAMPSET software
connected to the local RS-232 port on the relay.

It is possible to restore the password(s) in case the password is
lost or forgotten. In order to restore the password(s), a relay
program is needed. The serial port settings are 38400 bps, 8
data bits, no parity and one stop bit. The bit rate is
configurable via the front panel.

Send both the numbers to [e-mail] and ask for a
password break. A device specific break code is sent back to
you. That code will be valid for the next two weeks.

Now the passwords are restored to the default values (See
chapter 2.2.5).

2.3.4. Forced control (Force)

In some menus it is possible to switch a signal on and off by
using a force function. This feature can be used, for instance,
for testing a certain function. The force function can be
activated as follows:

1. Move to the setting state of the desired function, for

example DO (see Chapter 2.4, on page 27).

2. Select the Force function (the background color of the force

text is black).

Figure 2.3.4-1. Selecting Force function

3. Push the ENTER key.

4. Push the UP or DOWN key to change the "OFF" text to

"ON", that is, to activate the Force function.

5. Push the ENTER key to return to the selection list. Choose

the signal to be controlled by force with the UP and DOWN
keys, for instance the T1 signal.

6. Push the ENTER key to confirm the selection. Signal T1

can now be controlled by force.

7. Push the UP or DOWN key to change the selection from "0"

(not alert) to "1" (alert) or vice versa.

8. Push the ENTER key to execute the forced control operation

of the selected function, e.g., making the output relay of T1
to pick up.

9. Repeat the steps 7 and 8 to alternate between the on and off

state of the function.

10. Repeat the steps 1...4 to exit the Force function.

11. Push the CANCEL key to return to the main menu.

NOTE! All the interlockings and blockings are bypassed when the force control

is used.

2.4. Configuration and parameter setting

The minimum procedure to configure a relay is

1. Open the access level "Configurator". The default password

for configurator access level is 2.

2. Set the rated values in menu [CONF] including at least

current transformers and a protected transformer rating.
Also the date and time settings are in this same main
menu.

3. Enable the needed protection functions and disable the rest

of the protection functions in main menu [Prot].

4. Set the setting parameter of the enable protection stages

according the application.

5. Connect the output relays to the start and trip signals of the

enabled protection stages using the output matrix. This can
be done in main menu [DO], although the VAMPSET
program is recommended for output matrix editing.

6. Configure the needed digital inputs in main menu [DI].

7. Configure blocking and interlockings for protection stages

using the block matrix. This can be done in main menu
[Prot], although VAMPSET is recommended for block
matrix editing.

Some of the parameters can only be changed via the RS-232
serial port using the VAMPSET software. Such parameters,
(for example passwords, blockings and mimic configuration) are
normally set only during commissioning.

Some of the parameters require the restarting of the relay. This
restarting is done automatically when necessary. If a
parameter change requires restarting, the display will show as
Figure 2.4-1.

Figure 2.4-1 Example of auto-reset display

Press CANCEL to return to the setting view. If a parameter
must be changed, press the ENTER key again. The parameter
can now be set. When the parameter change is confirmed with
the ENTER key, a [RESTART]- text appears to the top-right
corner of the display. This means that auto-resetting is

pending. If no key is pressed, the auto-reset will be executed
within few seconds.

2.4.1. Parameter setting

1. Move to the setting state of the desired menu (for example

CONF/CURRENT SCALING) by pushing the ENTER key.
The Pick text appears in the upper-left part of the display.

2. Enter the password associated with the configuration level

by pushing the INFO key and then using the arrow keys
and the ENTER key (default value is 0002). For more
information about the access levels, please refer to Chapter

2.2.5.

3. Scroll through the parameters using the UP and DOWN

keys. A parameter can be set if the background color of the
line is black. If the parameter cannot be set the parameter
is framed.

4. Select the desired parameter (for example Inom) with the

ENTER key.

5. Use the UP and DOWN keys to change a parameter value.

If the value contains more than one digit, use the LEFT and
RIGHT keys to shift from digit to digit, and the UP and
DOWN keys to change the digits.

6. Push the ENTER key to accept a new value. If you want to

leave the parameter value unchanged, exit the edit state by
pushing the CANCEL key.

fault message will be shown when the setting is confirmed with
the ENTER key. Adjust the setting to be within the allowed
range.
