Ge eral:
In three phase systems it measures RMS values of AC voltages
currents and system frequency sensitively. Using up direction button
(Select) phase-neutral voltages and phase-phase voltages monitor
sequentially.
DP01-72 has many features.
Those are;
- Phase Failure (seq)
- Phase Sequence (seq)
- Over Voltage Protection (o - U)
- Under Voltage Protection (u - U)
- Voltage Unbalance (asymmetry) Protection (u b)
- Over Current Protection (o - C)
- Under Current Protection (u - C)
- Current Unbalance (asymmetry) Protection (ubC)
- Over Frequency Protection (o - F)
- Under Frequency Protection (u - F)
When device is turn on if its adjusted voltages and frequency in its
interval and if phase sequence is correct relay switch on.
If any of error occurred ( except phase failure and phase sequence )
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.

Phase Failure: (u-U)
Before starting system it controls phase absence then if all phases
exits Normal LED turn on and relay contact switch on. In case of
missing of any L1 L2 L3 phases Normal LED turn off and relay
switch off its contact .In this case u-U warn appears on display.

when pressing continuously
screen displays frequency of

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.
IMPORTANT: L1 - N is device supply inputs. Thus the applied L1 – 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.
Voltage U bala ced: (u b)
The phase-phase voltage unbalance limit can be adjusted
between(5% - 20%) . When it exceeds the adjusted limit the device
switched off its out contact at the end of t-1 delay. In this case u b
warn appears on the screen. For the returning normal state
asymmetry values should under 20% (hysteresis value). In this case
at the end of t3 time Normal LED turned on and output contact switch
on. If the phase-phase voltage unbalance return adjusted value
shorter than t-1 time output relay does not release its contact.
Hysteresis is 20 %.
u b = 000(oFF) protection is disable .
Example: Let's say that asymmetry value is set to %15 for a
3 x 380VAC.
In this case relay contact switch off at (380-(380x0.15))=323 V.
Switch on the contact is performed at 323+(380x%15x%20)= 334V.
(%20 is the hysteresis).

2.6 Asymmetric Curre t Protectio :
It can be set by the user between 5% and 40%. It controls the
asymmetric that may occur in the current of the three phases. That
may occur when one of the phases' voltage is low and the other one
is high. That may cause asymmetric current in the motor's bobbin.
This way the motor's bobbin is protected. Furthermore it protects the
motor from missing phase or a possible unplugged or cut wiring.
If the unbalance between the phases' current exceeds the adjusted
value the switch off occurs after t-1 delay.
If the current unbalance exceed the adjusted value Normal LED
turned off and output relay switch off. In this case ubC warn appears
on its screen.
This function can be disable if ubC value = 000 (oFF)
Over a d U der Curre t : (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 any current passing through any 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.

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)
Retur 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 Curre t Coefficie t : 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 Curre t Coefficie t : 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 : Locki g 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 : Locki g Cou ter ( 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.
