General
General
One of the common faults faced in industrial plants is over-heating and
burning of 3 phase motors due to the phase failure. “Thermicmagnetic
device” which is an essential element in motor protection is generally too
slow due to both its electro-mechanical structure and the use of high
current setting range to assure demarrage without tripping. Being designed
to eliminate the above disadvantages, MK-01, MK-01P and MKC-01,
MKC-01P Phase Failure Devices react within 0.2 sec. (fixed) against the
following faults and take the motor out of service.
FR-02 is an electronic device monitoring the L1, L2, L3 phase sequence.
Operation Principles
FR-02 Phase Sequence Device is developed to be used in three-phase
systems where correct phase sequence is important. If the input L1, L2
and L3 phases are in correct sequence, the LED on the front panel
remains ON and the internal relay is energized. When the phase sequence
is wrong, the LED turns OFF and output relay is inactive. In this case,
interchanging two phases will be sufficient to solve the problem.
General applications in which FR-02 phase sequence device is used,
are vessel pumping systems, air compressors, and elevators. The
unexpected false rotating direction of motors used with these systems
can cause injury to persons and damage the property.
1. PTC Protection (Available only in MK-01P and MKC-01P)
When the coil temperature in motors exceeds Tc, the limit temperature
of PTC, the output relay switches OFF immediately.
This feature is included MK-01P and MKC-01P. See Fig.1 for typical
resistance of PTC vs temperature characteristics for three different
switching temperatures (110 0C, 120 0C, 130 0C) normally, PT-110 is used
and it can be changed upon request. See Fig. 1.

Operation Principles
PT-01 Thermistor Device is developed to be used for PTC protection.
When the coil temperature in motors exceeds Tc, the limit temperature
of PTC, the output relay switches OFF immediately. See Fig.1 for typical
resistance of PTC vs temperature characteristics for three different
switching temperatures (110 0C, 120 0C, 130 0C) Normally, PT-110 is used
and it can be changed upon request. See Fig.1. As seen from Fig.1, the
PTC resistance is smaller than 100 W when T<Tc-50 and greater than
10K when T>Tc+50 .

Sanayi tesislerimizde yaygýn olarak kullanýlan elektrik motorlarýnýn iki faza
kalarak aþýrý ýsýnmasý ve yanmasý sýkça karþýlaþýlan arýza kaynaklarýndan
biridir. Motor korumasýnda sýk kullanýlan “Termik Manyetik Röle” gerek
elektro-mekanik yapýsý, gerekse demeraj akýmýnýn karþýlanabilmesi için
akým ayarýnýn yüksek tutulmasý nedeniyle, koruma iþleminde yetersiz
kalmaktadýr.
Bu olumsuz etkileri ortadan kaldýracak þekilde tasarlanmýþ bulunan
MK-01, MK-01P ve MKC-01, MKC-01P motor koruma röleleri aþa¤ýdaki
koruma fonksiyonlarýný yerine getirir.
FR-02 L1, L2, L3 fazlarýnýn sýrasýný kontrol edir.
Kullaným ve Çalýþma Prensibi
Giriþine gelen L1, L2 ve L3 fazlarý do¤ru sýralandý¤ý takdirde çýkýþ veren
FR-02 faz sýrasý rölesi, ters faz olayýnýn hayati önem taþýdý¤ý üç fazlý
sistemlerin korunmasýnda kullanýlmak üzere geliþtirilmiþtir. E¤er giriþteki
L1, L2 ve L3 fazlarý do¤ru sýrada ise röle üzerindeki LED yanýk ve çýkýþ
rölesi çekmiþ konumdadýr. E¤er fazlar ters ise LED söner ve çýkýþ rölesi
býrakýr. Bu durumda iki fazýn ba¤lantýlarýný de¤iþtirmek yeterli olacaktýr.
Genelde FR-02 faz sýrasý rölesinin kullanýldý¤ý alanlar, gemi pompa
sistemleri, hava kompresörleri ve asansörlerdir. Bu sistemlerde kullanýlan
motorlarýn ters yönde dönmesi kiþisel ve maddi hasarlara yol açabilir.
1. PTC Korumasý (Sadece MK-01P ve MKC-01P tipinde)
Motor sargý sýcaklý¤ý PTC’nin sýcaklýk sýnýr de¤erini aþarsa motor gecikmesiz
olarak devreden çýkartýlýr. Bu özellik MK-01P ve MKC-01P’de yer almaktadýr.
De¤iþik sýcaklýk sýnýr de¤erlerine (110 0C, 120 0C, 130 0C) sahip üç PTC’nin
direnç-sýcaklýk de¤iþimleri Þekil 1’de verilmektedir.

2. Gerilim Dengesizli¤i (Ayarlanamaz)
Nötr-Faz arasý gerilim dengesizli¤i %20’lik sabit de¤erden fazla oldu¤u
anda çýkýþ rölesi 0.2 sn içinde motoru devreden çýkarýr. Þekil 2’ye bakýnýz.
Üç fazlý sistemlerde gerilim dengesizli¤i (asimetri) yüklerin fazlara dengesiz ba¤lanmasý
sonucu oluþur. Gerilim dengesizli¤i motor sargý sýcaklý¤ýnýn belli bir miktar artmasýna
ve dolayýsýyla motor gücünün düþmesine neden olur.
