Genel
Sanayi tesislerimizde yaygýn olarak kullanýlan
elektrik motorlarýn iki faza kalarak aþýrý
ýsýnmasý ve yanmasý sýkça karþýlaþýlan arýza
kaynaklarýndan biridir. Motor korumasýnda

KORUMA FONKSÝYONLARI :
1- Gerilim Dengesizli¤i (Ayarlanabilir veya kapatýlabilir) (MKC-05 / 05P / 06 / 06P)
Üç faz sistemlerde gerilim dengesizliði (asimetri); klerin fazlara dengesiz baðlanmasý
sonucu oluþabileceði gibi, üç fazlý motorlarda fazlardan birinin kesilmesi durumunda
da oluþur. Bu durumda kesilen faza ait motor sargý ucunda, motorun der sargýlarý
üzerinden indüklenerek dönen gerilim görülür. Bu gerilim deðeri motorun cinsine ve
yük durumuna göre deðiþir.
Faz yokluðu veya herhangi bir sebepten oluþabilecek faz-faz arasý gerilim dengesizliði
kullanýcýnýn ayarladýðý asimetri deðerinden küçükse çýkýþ rölesi çekilidir.
Eðer gerilim dengesizliði ayarlanan asimetri derini (%5-15) aþarsa; çýþ rölesi
ayarlanan zaman gecikmesi (0,1-20sn.) sonunda býrakýr ve motor devre dýþý kalýr.
Cihazýn rölesi býrakýr, röle LEDi söner, Asimetri Hatasý ikaz LEDi yanar. Eðer gerilim
dengesizliði zaman gecikmesi bitmeden ayarlanan deðerin altýna inerse çýkýþ rölesi
çekili kalýr ve motor devreden çýkartýlmaz.
Uygulamalarýnýzda; motorun iki faza kalmasý esnasýnda motorun diðer sargýlarýndan
indüklenen gerilim deðerini de göz önünde bulundurarak cihaz üzerinden uygun asimetri
deðerini ayarlayýnýz.
Gerilim dengesizli¤i motor sargý sýcaklý¤ýnýn belli bir miktar artmasýna ve dolayýsýyla
motor gücünün düþmesine neden olur.
Asimetri sýnýr de¤erleri kullanýcý tarafýndan %5 ile %15 arasýnda ayarlanabilir veya
kapatýlabilir. Histerisis ayarlanan asimetri deðerinin %30u dur.
Örnek : 3 x 380 Vluk þebekede %10 asimetri varsa tek fazdaki açma de¤eri
380-(10x400/100)=340 V olarak hesaplanýr. Böylece devreye alma de¤eri :
380-((10-(10x%30))x400/100)=353,2 V olacaktýr.

getirmek için tasarlanmýþtýr.
Kullaným ve Çalýþma Prensibi
Ön paneldeki asimetri (%asm.) ayar düðmesi kullanýlarak korunacak olan sistemin üst
asimetri deðeri belirlenir. Sistemdeki dengesizlik(asimetri) ayarlanan deðerin üstüne
çýkarsa cihaz býrakma gecikmesi (Delay) kadar bekler ve bu süre sonunda dengesizlik
hala devam ediyorsa cihazýn rölesi býrakýlýr (OUT ledi söner ve Asm. Led'i yanar).
Sistemdeki dengesizlik ayarlanan deðerin altýna düþtüðünde ise cihaz çekme gecikmesi
(Reset Delay) kadar bekler ve bu süre sonunda dengesizlik hala ayarlanan deðerin
altýnda ise cihazýn rölesi çeker (OUT ledi yanar ve Asm. Led'i söner).
TRLÜ ÜRÜNLERDETR BAÐLANTISININ KOPMASI ( : MKC-05/05P/FR-02)
trlü ürünlerde Faz-Nötr arasý ölçüm yapýlmaktadýr. Nötr kablosu
koparsa; asimetrik faz klenmesi sonucu oluþan nötr noktasýnda bir
kayma meydana gelir. Cihaz ölçümlerini kaymýþ olan nötr noktasýna göre
yapmaya devam eder. MKC-05P Nötr ve L3 fazý arandan beslenir
nötrün kopmasý cihazýn enerjisinin kesilmesine ve rölesinin býrakmasýna
neden olur.

PHASE FAILURE DEVICES

A5049 Rev.2
EN
The voltage asymmetry causes the rise in motor temperature and a reduction of the
rated motor power.
Voltage asymmetry limit values can be adjusted between 5%-15% by the user or can
be disabled. Hysteresis is 30% of the adjusted asymmetry value.
Example: Given 3x380 V supply with 10% asymmetry,
Relay switches OFF at: 380-(10x400/100)=340 V
Relay switches ON at: 380-((10-(10x%30))x400/100)=353,2 V
Phase Sequence Fault Function Diagram
When the phase sequence is correct
(L1, L2, L3 in clockwise direction) the
output relay is activated; however, if
the sequence is changed by any
reason, the output relay switches OFF
immediately. Relay LED is OFF, Phase
Sequence error LED turns ON.

turn on simultaneously and the relay

4- Insufficient Supply Voltage
(MKC-05 / 05P / 06 / 06P and FR-02 )
In devices which are supplied from a 3 phase capacitive source(MKC-05/06), the
supply voltage is the mean value of voltages from all three phases. If this mean value
(L3 phase for MKC-05P/06P devices) is less than half the supply voltage, the relay
gives an insufficient supply voltage warning(asm. and Phs. Seq. LEDs flash alternately)
and the relay breaks contact without delay.

Precautions For Installation and Safe Use
Failure to follow those instructions will result in death or serious injury.
Disconnect all power before working on equipment.
When the device is connected to the network, do not remove the front panel.
Do not try to clean the device with solvent or the like. Only clean the device
with a dried cloth.
Verify correct terminal connections before operation.
Mount device to the panel.
Electrical equipment should be serviced only by your compedent seller.
No responsibility is assured by the manufacturer or any of its subsidiaries
for any consequences arising out of the use of this material.
General
One of the common faults encountered in
industrial plants is the overheating and the
resulting damaging of the 3-phase motors
due to the phase failure. Thermal-magnetic
relaywhich is an essential element in motor
protection is generally too slow to assure
demurrage without tripping due to both its
PROTECTION FEATURES :
1- Voltage Unbalance (Can be Adjusted or Disabled) (MKC-05 / 05P / 06 / 06P)
Unbalanced voltage(asymmetry) may occur when;
The mains are loaded with unbalanced distribution,
One of the 3 phases of the motor has lost. In this case, some amount of voltage
which is produced by other phases will be induced on the lost phase. Amount of this
voltage depends on both the motor type and amount of load.
Output relay is making contact when a phase has been lost or an unbalanced Phase-
Phase voltage value, which is occured for any reason, is smaller than the user defined
asymetrical value. If this unbalanced voltage value exceeds the adjusted asymetrical
value(5-15%); output relay will break contact and switch off the motor at the end
of adjusted time delay(0.1-20 sec.); relays LED on the front panel is turned off. Asymmetry
error LED is turned ON. If the fault disappears within the delay time, the output relay
will not break contact and will not switch off the motor.
In applications; a proper asymetrical value should be adjusted considering the
induced voltage value in two-phase which are remained after the other one has
lost.
electromechanical structure and the use of high current setting range.MKC-05-05P,
MKC-06-06P and FR-02 Motor Protection Relays which are designed to protect the
desired equipment against phase failure, asymmetry and phase sequence failure on
3 phase systems with or without neutral connection, are manufactured to serve the
following purposes.
Utilisation and Working Principle
By using the asymmetry adjustment knob(%asm.) on the front panel, the upper
asymmetry limit of the system which will be protected is determined. If the unbalance
on the system(asymmetry) exceeds the adjusted value, the device waits as long as
the Delay-OFF time(Delay) and if the unbalance is still over the adjusted value, the
relay of the device breaks contact(OUT LED turns off and Asm. LED turns on). If the
unbalance on the system(asymmetry) falls under the adjusted value, the device waits
as long as the Delay-ON time(Reset Delay) and if the unbalance is still under the
adjusted value, the relay of the device makes contact(OUT LED turns on and Asm.
LED turns off).

If motor coil temperature exceeds the
temperature limit of PTC, the motor is
disconnected immediately. The output relay
is opened and Relay LED turns off.
This feature is only available for MKC-05P
and MKC-06P. Resistance-Temperature
values for three PTC with different temperature
limit values (110 oC, 120 oC, 130 oC )
are shown on the figure on the right.
If you want to cancel PTC protection on a
device with PTC protection feature, the PTC
terminals on the device should be short-
circuited.
BREAK OF THE NEUTRAL CONNECTION FOR DEVICES WITH NEUTRAL
( :MKC-05/05P/FR-02)
In devices with neutral, Phase-Neutral measurements are taken. If the
neutral cable breaks, the neutral point of the system shifts because of
the asymmetrical phase loading. The device continues the take
measurements according to the shifted neutral system point. MKC-05P
is supplied from Neutral and L3 Phase. Break of neutral cable causes
the device to lose supply and the relay to open.
