Genel
Sanayi tesislerimizde yaygýn olarak kullanýlan elektrik motorlarýnýn iki faza kalarak
aþýrý ýsýnmasý ve yanmasý sýkça karþýlaþýlan arýza kaynaklarýndan biridir. Motor
korumasýnda sýkça kullanýlan termik manyetik röle gerek elektromekanik yapýsý,
gerekse demeraj akýmýnýn karþýlanabilmesi için akým ayarýnýn yüksek tutulmasý
nedeniyle, koruma iþleminde yetersiz kalmaktadýr.
Bu olumsuz etkileri ortadan kaldýracak þekilde tasarlanmýþ bulunan MK-05,
MKC-05, MKC-06, MK-06 Motor Koruma Röleleri aþa¤ýdaki koruma fonksiyonlarýný
yerine getirir:
4- Yetersiz Besleme Voltajý
PK21 kutusunda MK-05 ile MK-05P cihazlarýnda L1 fazý, MKC-05 ile
MKC-05P cihazlarýnda L3 fazý besleme fazýdýr. Besleme fazý cihazýn iþletme geriliminin
PK21 kutusunda MKlar ve MKCler için %60-65in altýna düþtü¤ü zaman röle
gecikmesiz açma yapar ve hata LEDleri sýrayla yanýp sönmeye baþlar.
2- Faz sýrasý
Faz sýrasýnýn ters oldu¤u durumlarda (L1, L2, L3 saat yönünde de¤il) motor devreye
alýnmaz. Herhangi bir nedenle faz sýrasý bozulursa motor gecikmesiz devreden
çýkarýlýr. Cihazýn rölesi býrakýr, Röle LEDi söner, faz sýrasý hatasý ikaz LEDi yanar.

tipinde)
Motor sargý sýcaklý¤ý PTCnin sýcaklýk sýnýr de¤erini aþarsa motor geçikmesiz olarak
devreden çýkartýlýr. Cihazýn rölesi býrakýr, Röle LEDi söner.
Bu özellik sadece MK-05P, MKC-05P ve MK-06P, MKC-06Pde yer almaktadýr.

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. Histerisis
%20 dir.
Örnek : 3 x 380 Vluk þebekede %10 asimetri varsa tek fazdaki açma de¤eri
380-( 380 x %10 )= 342 V olarak hesaplanýr. Böylece devreye alma de¤eri :
342 + ( 342 x 10% x %20 )= 348.8 V olacaktýr.
1- Gerilim Dengesizli¤i (Ayarlanabilir)
Üç fazlý sistemlerde gerilim dengesizliði (asimetri);
Yüklerin fazlara dengesiz baðlanmasý sonucu oluþabileceði gibi,
Üç fazlý motorlarda fazlardan birinin kesilmesi durumunda da oluþur. Bu durumda
kesilen faza ait motor sargý ucunda, motorun diðer 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 deðerini (%5-15) aþarsa; çýkýþ rölesi
ayarlanan zaman gecikmesi (0,1-10sn.) sonunda býrakýr ve motor devre dýþý kalýr.
Cihazýn rölesi býrakýr, röle LEDi söner, Asimetri Hatasý ikaz LEDi 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.

General
One of the common faults faced in industrial plants is overheating and damaging
of 3 phase motors due to the phase failure. Thermic-magnetic device which is an
essential element in motor protection is generally too slow due to both its
electromechanical structure and the use of hing current setting range to assure
demarrage without tripping. Being designed to eliminate the above disadvantages,
MK-05, MKC-05, MKC-06 and MK-06 Phase Failure Devices serve the following
protection features

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 when wiring.
Electrical equipment should be serviced only by your compedent seller.
Mount device to the panel.
A2910 / Rev.8
1. Voltage Unbalance (Adjustable)
Unbalanced voltage may occured when;
The mains are loaded with unbalanced distribution,
One of the 3-phase of motor has lost. In this case, some amount of voltage which
produced by other phases will be inducted on the lost phase. Amount of this value
depends on both the motor type and amount of load.
Output relay is activated when a phase has lost or an unbalanced Phase-Phase
voltage value, which is occured with 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 release itself and switches off the motor at the end
of adjusted time delay (0.1-10 sec.); Relays LED is turned off. Asymetry error LED
is turned ON. If the fault has gone within the delay time, the output relay is remoined
and will not switch off the motor.
In Applications; a proper asymetrical value should be adjusted regarding to the
inducted voltage value in two-phase which are remained after the other one has
lost.
The voltage asymmetry causes the rise in motor temperature and a reduction of
the rated motor power.
Voltage asymmetry limit values are adjusted (5%-15%) by the user.
Hysteresis is fixed at 20%.
Example: Given 3x380 V supply with 10% asymmetry,
Relay switches OFF at: 380-(380 x10%)=342 V
Relay switches ON at: 342 + (342 x 10% x 20%)=348.8 V
2. Phase Sequence
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 is
ON.
3.PTC Protection (Only Available in MK-05P, MKC-05P,
MKC-06P & MK-06P versions)
When the coil temperature in motors exceeds Tc, the limit temperature of PTC, the
output relay switches off immediately, Relay LED is OFF. This feature is included
only in MK-05P,MKC-05P,MK-06P and MKC-06P. See following figure for typical
resistance of PTC vs temperature characteristics for three different swiching
temperatures (110 oC, 120 oC, 130 oC). Normally, PT-110 is used and it can be
changed upon request.
5. Insufficient Supply
L1 is the supply phase of the MK-05 and MK-05P in PK21 package while L3 is the
suply phase of MKC-05 and MKC-05P devices. For MK and MKC devices if supply
voltage falls below 60-65% of rated voltage, output relay switches off without delay
and error leds start to blink one after another sequentially.
