1. INTRODUCTION
1.1 Front Panel View
1) LCD Screen: All powers, ratios, values, warnings and menu parameters are monitored on the screen.
Screen lighting gets off automatically if no key is pressed for 2.5 minutes in operating mode. In this case
it is sufficient for user to press a key to light the screen again.
2) Program (SET) Key: The key to enter the menu, switch to a submenu and keep the settings.
3) Exit (ESC) Key: It enables to return to the previous process in the menu and exit from the menu.
4) Up Key: It enables to move upward in measurement and menu position.
5) Down Key: It enables to move downward in measurement and menu position.
6) Stage LEDs: 12 pieces. (18 pieces in 18-stage relays. 22 pieces in 22-stage relays.) The stages are
stated on each LED. When the LED is on, it is understood the relevant LED is activated.
7) Energy (Power) LED: The LED indicating as PWR on Leksan. When there is energy in the device,
this green coloured LED gets on. If it does not get on, there is a problem in the supply.

1.2 Functions of Key
8) Alert Led: It gets on when the system exceeds 15% cap and 20% end limits.
9) Gen Led (for SMART S18, SMART SOG1, SMART SOG5 ): It gets on when the system is
supplied from the generator.
10) Communication Led: This led flashes during communication.
11) Capacitive Led: If total flowing capacitive reactive energy is above capacitive limit, this led gets
on.
12) Normal Led: If total flowing reactive energy from all phases is below End/Cap limits in relays,
normal led gets on.
13) Inductive Led: If total flowing inductive reactive energy is below inductive limit, this led gets on.
14) Error Led: When thermal input is opened, in the errors of connection and stage, no phase error,
excessive inductive/capacitive errors, this led gets on. If the led gets on continuously, errors still exist.
If error message is seen on the screen and alarm led is off, this means the errors occurred in the past
and do not exist at the moment. In this case, the errors can be deleted by long press of ESC key.
It is used to enter the menu and move to the next screen. Press this key for 3 sec to enter the
menu. In order to store parameter which is set in the menu, press SET key and move to the
next menu.
It enables to return to the previous process and exit from the menu.
It is used to change option and increase parameter value in the menu. Out of the menu,
it ensures that the current display does not change for 1.5 minutes in operating time. The
screens start to change automatically 1.5 minutes later. This key is used to enter stage values
manually
during stage test.
It is used to change option and decrease parameter value in the menu. Out of the menu, it is
used to change screen from current to the next in operating time. The new screen stays
unchanged for 1.5 minutes. The screens start to change automatically 1.5 minutes later.
During the stage test, this key is used to pass the tested stage and proceed to the next stage
test.

1.3 Relationship of Key
- If you hold down up key in the stage test, the manual login screen for that stage comes up.
- If you hold down down key in the stage test, the current stage test is passed by via its previous
value.
- If you hold down ESC key in any test, the test is cancelled.
- In manual stage login, the value of each phase is entered separately. Transition between phases
is done by pressing SET key. If you hold down ESC key during transition, the previous value
of the phase is entered to another phase.
- FORMAT: Give energy to the device by holding down SET key and wait 5 sec in this position
and press ESC key then leave firstly SET key and secondly ESC key; the format screen comes
up.
If we cannot to use a stage to report a load that the relay does not see:
A load (capacitive effect of long OG cables or inductive loss of power transformer) that current
transformer does not see can be defined to relay via ‘off set stage’. For this process; firstly one
of the stages is defined as ‘off set’, then apply ‘stage test’ to this stage and enter the convenient
value is entered from manual login menu.
EXAMPLE: The OG cable distance between electric meter and power transformer = 500m
The capacitive effect of the cable = 25 kVAr (for 34.500 V voltage and 95 mm2 XLPE
cable)
In this case, even if the relay makes cosՓ as 1, the meter will write capacitive due to the
capacitive effect of the cable. Reactive difference between the meter and the relay can be
eliminated by making the necessary settings in the ‘off set’ stage menu of SMART SVC
RELAY.
To activate a stage manually;
If you want to activate a stage manually, select the relevant stage as ‘off set’ stage. The relay
will activate that stage manually after this process.
To take a stage as a load to the system;
Select the relevant stage as ‘off set’. Then select the value of off set from ‘off set’ login screen
as 0 or test ‘off set’ stage by coming the stage test and enter the value as 0 for each phase. After
this process, the relay will activate that stage as a load.
If we want to report a value that the relay does not see but the meter sees, we associate this
value to a stage and report to the relay. We name this stage as ‘off set’ stage. This can be any
idle stage. After we enter the number of this stage in ‘off set’ login in the menu, we come to
stage test in the menu and test this stage then we enter the value of the stage for each phase as
‘off set’ value that the relay does not see in manual screen.

1.4 Smart Relay Features
It is microprocessor based.
It provides easy compensation for the loads entering and exiting fast.
As it is semiconductor controlled, the lifetime of power multiples is much
longer than contactors.
Since the sensing current is 3 mA, it can easily operate in small power
plants or even in large power plants with high current transformer ratio.
It provides full compensation even with aged or faulty capacitors.
With the help of the power flow graph, the business can be easily
analyzed. Maximum and minimum capacitor/reactor sizes required for
each phase and phase imbalances can be determined.
Detects faulty stage, excessive inductive/capacitive, phase error,
connection error etc. and informs the user.
With automatic stage test, stage values are continuously updated.
It has automatic detection and correction of current transformer
connection changes.
While extending the compensation maintenance period, it also reduces
maintenance costs.
Smart SVC Relay Instruction Manual
We can make ‘off set’ feature that is activated on any stage active or passive via an external
signal. The generator input of relay can be used for this application by changing “off set” to
“pin on” in the menu. When 220 Volt comes to generator input, ‘off set’ feature gets activated.
Otherwise it gets passive.
EXAMPLE: Assume that in our system we have a cogeneration that gives capacitive load
of approximately 200 kVAr and it outputs to OG line via a step- up transformer. Let our
compensation to be on AG side. We can use existing ‘off set pin’ feature to report to relay that
there is a 200 kVAr capacitive load, that the relay does not see in the system when the
cogeneration operates, and this load disappears when it is out of order. If a 220V output, that
is taken when cogeneration is activated, is connected to this ‘off set pin’ input, the ‘off set’
value (200 kVAr), that we entered to the relay before, gets activated and the relay compensates
according to this. When cogeneration is passive, the relay realizes this by pin login and makes
‘off set’ value, that is entered before, passive.
In the case of alarm when the screen flashes (when it passes to 20% end or 15%kap), the
alarm led gets on and the alarm contact outputs in the alarm output. When gen gets activated
and 220 Volt entered to gen input, this led gets on.
NOTE:The “Off set”stage must be idle or you should make it ineffective by cutting the stage
energy. You can make it ineffective in the menu. (by making “off set out put”selection off).
NOTE:To get more information, you can call technical support numbers and get more detailed
explanation.
