1.0 Introduction
The purpose of this manual is to provide information necessary to install, operate and maintain the
Mikro MK3000L relay.
MK3000L provides protections for 3 independent phase overcurrent elements and one non-
directional earth-fault element. All these elements are connected to the current transformers of the
feeders to be protected. There are 2 sets of current inputs, for 1Aand 5A rated CTs.
The relay comes with liquid crystal display (LCD) with 2 x 16 back-lit alphanumerical characters
and 7 LEDs in which 4 of the LEDs are programmable. An 8 button keypad can be used to access
all measurements, alarm or trip records and settings. Dedicate Open CB (circuit breaker) and Close
CB button is used to manually open and close CB.
There is a RS232 port available on the front panel and a RS485 port on the rear terminals. Using
MODBUS RTU protocol, all stored information including alarm, trip and disturbance records can
be read and settings can be modified with a PC loaded with setting software.
MK3000L has 4 configurable output relays. They can be activated by any of the protection
functions available in the relay. There is also 1 output relay for internal fault indication. There are 2
configurable logic inputs for various functions.

2.0 Front Panel
Using the front panel, the user can easily navigate through the user friendly menu, read
measurements and change settings. The relay status and alarm or trip records are displayed on the
back-lit LCD also.
MK3000L Front panel
2.1 LCD Display
The LCD has 2 lines with 16 characters each. Back light is on when a key is pressed and remain on
for predefined time duration. The brightness can be adjusted to suit the lighting conditions.
2.2 Keypad
There are 8 keys on the front panel.
Up, Down, Enter and Esc are used to navigate through the menus and adjust the settings.
Up : Scroll up the menus or increase setting value.
Down : Scroll down the menus or decrease setting value.
Esc : To exit from menus, submenus or to cancel setting value change. Press and
hold for 1.5 seconds to return to default display from any submenu.
Enter : To enter submenus or to confirm setting value change.
Clear : To reset tripping, reset latched relay. If “CLEAR” Scroll is enabled (under
Configurations-> Display menu) and during no alarm status, it can be
used to scroll through Phase Overcurrent and Earth Fault settings, and to
return to default display from any submenu if pressed and hold for 1.5
seconds.
Record : To display Alarm records. To display successive records, press Record key
again.

2.3 LEDs
Aux LED : Indicates auxiliary power to the device
Trip LED : Indicates tripping.
Alarm LED : Blinks to indicate non acknowledge alarm (or tripping). Steady on when
the alarm is acknowledged by pressing any key
Programmable LED : 4 Programmable LED can be programmed to turn on when one or more
linked function trigger.
2.4 RS232 Port
The front panel RS232 port has the same MODBUS RTU protocol as the RS485 port on the rear
terminal, though with fixed communication settings: 38400bps, 1 stop bit, even parity, address 1.
All stored information can be read and settings can be modified with a PC loaded with the supplied
setting software.
2.5 Default Display
By default the LCD displays the current value measured for IL1, IL2, IL3 and Io. Input and output
status as well as date and time can be shown by pressing Up key or Down key to change the default
display page. Pressing Esc key always return to current value display.
As soon as an alarm or trip is detected, the display jumps to alarm record display to show the latest
record.
2.6 Alarm Condition
During an alarm or tripping condition, Alarm LED blinks. Alarm record pops up. Any keypress
change the Alarm LED to steady on.
Example of Alarm record title page, showing record 1 out of total 2
records. Press Enter to enter sub page for this record. Press
Record/Down to show next alarm. Press Up to show previous alarm.
Press Esc to return to Default Display. Press Clear to clear the alarm.
If the condition still persists, the alarm cannot be cleared.
Alarm record sub page, showing record date and time. Press
Esc/Enter/RECORD to return to Alarm Record title page.
Clearing all record menu is shown when Up is pressed during display
of Record 1's title page, or RECORD/Down is pressed during display
of Last records title page. Press Clear to clear all Alarm record or Esc
to cancel.
2.6.1 Alarm Auto Scrolling
10 seconds after alarm record pops up, the Alarm display will be auto scrolled to show sub page and

subsequently next records until all the records are shown and repeats. Each page is shown for 5
seconds. Example when there are 2 alarm records:
Record 1 Title Page Record 1 Sub Page Record 2 Title Page Record 2 Sub Page Record
1 Title Page ….
Any key pressed stops auto scrolling. After 2 minutes of no activity, with which display still
showing the alarm record, auto scrolling starts again.
3.0 Password
3.1 Password Protection
Relay settings can be view anytime but locked from being changed. A password is required for
changing setting and CB Open, CB Close button pressed.
The password consists of four digit numbers. The factory default password is set as 0000.
The programming mode is indicated with the letter "P" on the right hand side of the display. The
letter "P" remains present as long as the password is active. (2 minutes if there is no key action).
3.2 Password Entry
The input of the password is requested as soon as a modification of a parameter is made or
Open/Close CB button is pressed. The user enters each one of the 4 digits by using up or down key
and validates each digit with Enter. If Esc is pressed in between, the password entering is
terminated.
“Password OK” is shown if correct password is entered. “Password ERROR” is shown if wrong
password is entered.
The display returns to the point of the preceding menu. Pressed Enter again to modify the setting.
If no key is pressed after 2 minutes, the settings are locked. A new password
request is associated with any subsequent setting change.
3.3 Changing Password
To change the password, go to Op Parameter -> Password menu. Enter current password to unlock,
after that the display shows current password. Press Enter again to enter the new password.
4.0 Menus
The menu is divided into 9 main menus and their corresponding submenus. To enter Main menu,
press Enter during default display.
The menu can be navigated by pressing Up, Down, Enter and Esc keys. There is no need of a
password when reading settings and measured values.

Note: The CT secondary should be connected to 5A or 1A CT input terminal according to the CT
secondary current rating. The display current is calculated by the formula:
Current at CT input terminal / CT input terminal type x CT Pri (setting above)
For example:
Current at CT input terminal = 3A,
CT input terminal type = 5A,
CT Pri = 200A,
The display value = 3/5 x 200 = 120A
Current at CT input terminal = 3A,
CT input terminal type = 1A,
CT Pri = 100A,
The display value = 3/1 x 100 = 300A

Io> menu
Set to Yes to enable earth fault first threshold (Io>). Then the
following menu is displayed.
Set the value for the current threshold Io>.
NOTE : When delay type is IDMT, the maximum setting
recommended should be 0.5Ion..
Set the time delay type of Io>. Setting choices are: IDMT and Definite
Time.
If Definite Time is selected, the following menu is displayed:
Set the value for the time delay of Io> definite time.
If IDMT is selected, the following menu is displayed:
Set the type of curve.
Set the time multiplier setting value for the curve.
Io>> menu
Set to Yes to earth fault second threshold (Io>>). Then the following
menu is displayed.
Set the value for the current threshold Io>>.
Set the value for the time delay of Io>> definite time.
Io>>> menu
Set to Yes to enable earth fault third threshold (Io>>>). Then the
following menu is displayed.
Set to yes to enable Io>>> operated on current sample base. Otherwise
it operates on fundamental value. Sample base method will ensure fast
tripping on highly saturated current signal.
