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.
