First parameter ;
o- : Over Voltage Setting between 390 V – 460 V can be set)
Between phase-phase voltages ,in case of over adjusted values, device end of the
time t-1 output relay switch off its contact .
u- : nder Voltages Setting between 300 V – 370 V can be set)
Between phase-phase voltages ,in case of under adjusted values, device end of
the time t-1 output relay switch off its contact .
unb : nbalanced Voltage (asymmetry) Setting 0,05 – 0,20 )%5 – 20
Between phase-phase voltages ,in case of under adjusted % value,device end of
the time t-1 output relay switch off its contact .
t-1 :On Delay Time (Voltages) 00,1 – 99,9 sec)
When occurred over voltage , under voltage and unbalanced voltage, if error
stretch t-1 time ,device out relay switch off.
t-2 : On Delay Time (Frequency) 00,1 – 99,9 sec)
When over and under frequency occurred, if error stretch t-2 time, device output
relay switch off.
t-3 : Returning Delay (Voltage and Frequency) 00,1 – 99,9 min)
To close the output contact after opening because of both voltage and frequency
faults ,the values should return to the normal ranges and after t-3 delay, the
device switch on its output contact.
L-C : Locking Counter oto , 001 – 010 piece )
The number of the faults allowed within the period L-t). If the number of faults
exceeds this adjusted counter value then the device locks itself.
The user must press Reset button after the device locks itself.
If L-C is set to oto then this property is disable.
L-t : Locking Time 001 – 060 min. )
The device locks itself when the number of faults reaches the adjusted locking
number within this locking time. This way the system is protected and the user has
the chance to nvestigate the problem.
Installation Instruction :
- Read the user instructions and caution before installation
- Be sure that the panel you are installing in when power off.
- The device designed to be installed to the rail where the installation tap
into the panel,
- Do not under case open the front of device.
- You should open the Terminals at the back side of the device after you
must be sure that there is no power in the panel.
Connect the device as shown in the connection scheme.
- Be sure that the terminals are connected tightly to the device.
- Use a power switch between the network line and the device's supply.
Moreover you should connect the 1A rapid fuse before measurement
inputs for device protection.
- If you are having any problem you can contact to KAEL Electronics Co.
where you can reach address given below.

o-F : Over Frequency Adjustment
It can be set between o-F) = [ u-F) + 0,4]............ 70 Hz.
If it is set to o-F = oFF then this protection is disabled.
u-F : nder Frequency Adjustment
it can be set between u-F) = 40 Hz ......................[ o-F) - 0,4].
If it is set to u-F = oFF then this protection is disabled.
