Güvenli Kullaným ve Kurulum Ýçin Uyarýlar
Aþaðýdaki talimatlara uyulmamasý halinde yaralanma veya ölümle sonuçlanabilecek durumlar ortaya çýkabilir. Cihaz üzerindeki herhangi bir iþlemden önce tüm besleme gerilimlerini kesiniz. Cihaz þebekeye baðlý iken ön paneli çýkarmayýnýz. Cihazý solvent veya benzeri maddelerle temizlemeyiniz. Cihazý temizlemek için sadece kuru bez kullanýnýz. Cihazý çalýþtýrmadan önce baðlantýlarýnýn doðru olduðunu kontrol ediniz. Cihazý panoya monte ediniz. Cihazýnýzdaki herhangi bir sorunda yetkili satýcýnýzla temas kurunuz.

Çalýþma Prensibi
AKC-01D / AKC-03D motor veya koruduðu sistemin akýmýný ölçer ve bu ölçülen akým deðeri ayarlanan akýmýn (Iset) altýnda ise motoru veya koruduðu sistemi devreden çýkarmak için kullanýlýr. Akým Iset deðerinin üzerinde ise çýkýþ rölesi çekili (ON) konumdadýr. Þayet akým Iset deðerinin altýnda bir deðere ulaþýrsa ayarlanabilir bir bekleme gecikmesi sonunda röle býrakýr (OFF) ve baðlý olduðu motoru veya sistemi devreden çýkarýr. Aþaðýdaki grafiklerde bu durumlar açýklanmýþtýr.

General
AKC-01A /AKC-03A Over Current Monitoring Devices are designed to protect motors and systems against over current with a current adjustment and two delay adjustments (start-up and tripping). Start-up delay is developed in order to prevent false contact turn-off arising from initial motor start-up (demurrage) currents.
Operation Principles
AKC-01A device measures the current of motor or protected systems and are utilized to turn-off the motor or protected systems when measured current is above the adjusted level. When the current value is lower than Iset value, the output relay is switched on. When the current value becomes higher than Iset value, the output relay is switched off after an adjustable tripping delay time and the motor or protected system is turned off. Please see following figures. For circumstances that the current value becomes higher than Iset value, start-up delay (adjustable: 1-6 sec. ) is developed in order to prevent false contact turn-off arising from initial motor start-up currents.

AKC-01D / AKC-03D UNDER CURRENT MONITORING DEVICE General
AKC-01D / AKC-03D Under Current Monitoring Devices are designed to protect motors and systems against under current with a current adjustment and two delay adjustments (start-up and tripping). Start-up delay is developed in order to prevent false contact turn-off arising from initial motor start-up (demurrage) currents.
Operation Principles
AKC-01D / AKC-03D device measures the current of motor or protected systems and are utilized to turn-off the motor or protected systems when measured current is below the adjusted level. When the current value is higher than Iset value, the output relay is switched on.

Technical Data
AKC-01A/AKC-01D Connection Diagram
AKC-3A / AKC-3D series must be used if current exceeds 5A.
AKC-03A/AKC-03D Connection Diagram
AKC-03A / AKC-03D is only used with CT-25 current transformer. In order to reach the solution; CT-25 current transformer must be used with turn numbers in the current intervals as in the table.
Table 1
If you use AKC-03 device 2-20A interval, CT-25 current transformator must be encircled with 3 turns of the cable that current flows. At that time, I set scale takes the values below. 1,5x=2A, 3x=4A, 6x=8A, 9x=12A, 12x=16A, 15x=20A
According to Table 1
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
No responsibility is assured by the manufacturer or any of its subsidiaries for any consequences arising out of the use of this material.
