General:
In one phase systems, it measures R S values of AC voltage,
current and system frequency sensitively.
ke-DP02 has many features.
Those are;
- Over Voltage Protection (o - U)
- Under Voltage Protection (u - U)
- Over Current Protection (o - C)
- Under Current Protection (u - C)
- Over Frequency Protection (o - F)
- Under Frequency Protection (u - F)
When device is turn on if its adjusted voltage and frequency in its
interval relay switch on.
If any of error occurred at the end of adjusted time relay switch off
its contact. When system return normal values, at the end of time
out relay switch on.
IMPORTANT: L - N is device supply inputs.
Thus,the applied L – N voltage must be
rated voltage of system . Otherwise normal
led makes flash and the device switched off
its output contact.
The measured frequency also must the
frequency of the system.
Special Buttons:
Select: (Up direction)
when pressing continuously,
screen displays frequency of
system. When button release
device continue to show voltage.
Reset:
If error case although disappeared
then device is not return to normal,
latch-function occurred and it
makes locked device.
Or Lock-function (only for currents)
may be occured.
After checking error in system then
restart device with pushing reset
button.

Over and Under Voltage : (o-U),(u-U)
Under voltage (u-U) it can adjusted between Umin= (180 – 225 V).
Over voltage (o-U) it can adjusted between Umax=(235 –275 V).
If the voltage drops below the adjusted under voltage limit, when u-U
shows on the screen and device switch off its output contact end of the
t-1 time Normal LED turned on .In this case u-U warn appears on the
screen.
If the voltage exceed the adjusted over voltage limit, Normal LED
turned off and output relay switch off. In this case o-U warn appers on
its screen.
Hysteresis is 6 V.

Over and Under Current : (o-C),(u-C)
Under Current (u-C)
Over Current (o-C)
When the current of the protected system goes below the adjusted
value it switches off its output contact after d-t delay.
Normal LED turn off and relay switch off its contact .In this case
u-C warn appears on display.
When current passing through phase of the protected system
exceeds the adjusted value the device switches off its output contacts
after a proper time (d-t).Normal LED turn off and relay switch off its
contact .In this case o-C warn appears on display.
NOTE: Under current protection set value with its hysteresis must not
overlap with over current protection set value with its hysteresis or, the
under current protection set value must not be higher than the over
current protection set value.

r-t r-t
Start delay time: Sd-t
It can be set between 1 and 60 seconds.It is used to prevent the switch
off from occurance because of the motor's inrush current.
This function can be disable if Sd-t value = 000 (oFF)
Return Time : r-t
it shows the delay time that device will wait to switch on its output relay
when failure ends after a switch off. It can be set between 0,5 and 99,9
seconds.
Very Over Current Coefficient : VOC (Current Very Sudden Switch
Off Protection)
It can be set by the user between 2,1 and 6.
When the current value exceeds the adjusted value within the start
delay time, the device switches off, its output contact immediately.
Very Over Current value = (o – C) x (VOC)
This function can be disable if VOC = 000 (oFF)
Over Current Coefficient : OC (Current Sudden Switch Off Protection)
It can be set by the user between 1,1 and 2.
When the current value exceeds the adjusted value without the start
delay time, the device switches off, its output contact immediately.
Over Current value = (o – C) x (OC)
This function can be disable if OC = 000 (oFF)

Under Frequency be able to set between(u-F) = 40 Hz ...[(o-F) -0,4]
Over Frequency be able to set between (o-F) =[(u-F) + 0,4]...70 Hz
If required , it can be set only under frequency or only over frequency
protection as well as both of protection can be disabled.
If o-F = 55 Hz and u-F = oFF set, device works as over
frequency protector only. (if system frequency above 55 Hz, under
screen displays o-F warning and end of time t-2 relay switch off its
output contact )
if o-F = oFF and u-F = 45 Hz set , device works as under
frequency protector only . (if system frequency below 45 Hz, under
screen displays u-F warning and end of time t-2 relay switch off its
out contact.)
if o-F = oFF and u-F = oFF set, frequency protection is disabled.
LOCKING FUNCTION :
It can be controlled by two parameters. Locking time and
Locking counter. If the number of opening reaches the adjusted
locking counter withing the adjusted locking time then device
switch off its contact and locks its functions until the user
pressed Reset button.
If the locking counter is adjusted to oto then this function is
disable and device never locks itself.
L-t : Locking Time ( 001 – 060 min. )
It is well know the frequently occurring faults may damage
system. For that the device when number of faults reaches the
adjusted locking number within this locking time. This way the
system is protected and user has chance to investigate the
problem.
L-C : Locking Counter ( oto , 001 – 010 piece )
The number of faults allowed within the period L-t. If number of
faults exceeds this adjusted counter value device locks itself.
In this case (- - -) warn appears on its screen. User must press
Reset button then the fault passes in order to unlock the device.
If L- C is set to oto then this property is disabled.
