AKC-01A / AKC-03A Aþýrý Akým Koruma Rölesi; motorlarý ve sistemleri aþýrý

akýma karþý korumak için tasarlanmýþtýr. Bir akým ayarý ve iki gecikme(Iset)

ayarýna (baþlama ve bekleme) sahiptir. Baþlama (start) gecikmesi, motor

kalkýþ (demeraj) akýmý nedeniyle oluþabilecek hatalý açmalarý önlemek

amacýyla geliþtirilmiþtir.

Çalýþma Prensibi

ölçülen akým deðeri ayarlanan akýmýn üzerindeyse motoru veya(Iset)

koruduðu sistemi devreden çýkarmak için kullanýlýr.

Akým deðerinin altýnda ise çýkýþ rölesi çekili (ON) konumdadýr. ÞayetIset

akým deðerinin üzerinde bir deðere ulaþýrsa ayarlanabilir bir beklemeIset

gecikmesi sonunda röle býrakýr (OFF) ve baðlý olduðu motoru veya sistemi

devreden çýkarýr.

Aþaðýdaki grafiklerde bu durumlar açýklanmýþtýr.

Akým deðeri deðerini aþtýðýnda, motor veya sistemin kalkýþ (start) akýmýIset

etkisi ile hatalý açmasý 1-6 sn ayarlý baþlama (start) gecikmesi ile önlenir.

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 value, the output relay is switchedIset

on. When the current value becomes higher than value, the output relayIset

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 value,Iset

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 value, the output relay is switchedIset

on. When the current value becomes lower than value, the output relayIset

is switched off after an adjustable tripping delay time and the motor or

protected system is turned off.

Please see following figures.

Start-up delay (adjustable: 1-6 sec. ) is developed in order to prevent false

contact turn-off arising from initial motor start-up currents.

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.
