KAEL DP-01-96 User manual

1.3 The Use Of Password
The device has a changeable password to make an easy access to the menu.
The password prevents unauthorized people from changing the system setting.
Incase of wrong password input, the user can go through the menu and view
the set values but can not change these values.
Correct password input allows the user to go through the menu and change any
adjusted value. The first use value is “ 234”.
2. Protections:
2.1 Over Voltage Protection:
The over voltage limit can be set by the user between 230 and 270 volts.
When the Neutral-Phase voltage of the protected system exceeds the
adjusted value the device switches off its output contacts after a proper time
(t3). If the voltage returns to normal value before the end of the (t3) period
then the switch off does not happen. After a switch off of an over voltage
alarm, while automatic reset is selected, if the voltage value returns to the
normal value then switch on occurs after a proper period (T-on). If manual
reset is selected, the switch off will continue until the operator pushes the
reset button. Pressing the set button for 3 seconds resets the device.
2.2 Under Voltage Protection:
The under voltage limit can be set by the user between 70 and 2 0 volts.
When the Neutral-Phase voltage of the protected system exceeds the
adjusted value the device switches off its output contacts after a proper time
(t3). If the voltage returns to normal value before the end of the (t3) period
then the switch off does not happen. After a switch off of an under voltage
alarm, while automatic reset is selected, if the voltage value returns to the
normal value then switch on occurs after a proper period (T-on). If manual
reset is selected, the switch off will continue until the operator pushes the
reset button. Pressing the set button for 3 seconds resets the device.
2.3 Asymmetric Voltage Protection:
It can be set by the user between %5 and %40. When an unbalance occurs
between the phases then the device switches off the output contact after the
t3 time. If the unbalance returns to normal value before the end of the (t3)
period then the switch off does not happen. After a switch off of an
asymmetric voltage alarm, while automatic reset is selected, if the voltage
value returns to the normal value then switch on occurs after a proper period
(T-on). If manual reset is selected, the switch off will continue until the
operator pushes the reset button. Pressing the set button for 3 seconds
resets the device.
2.4 Over Current Protection:
The current limit can be set by the user between x 0. and x of the current
transformer value. 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 (t2). If the current value goes over .5
times over the adjusted current value the device will wait for no delay and
switches the output contacts immediately. The over current protection goes
active after the start delay time in motor and full protection modes (Pgr2 and
Pgr3), while in system protection mode (Pgr ) no start delay time is applied
then the over current protection starts immediately. After a switch off of an
over current alarm, while automatic reset is selected, if the current value
returns to the normal value then switch on occurs after a proper period (T-on).
If manual reset is selected, the switch off will continue until the operator
pushes the reset button. Pressing the set button for 3 seconds resets the
device.
2.5 Current Sudden S itch Off Protection:
It can be set by the user between (I)s x2 and (I)s x 0 of the over current
value. When the current value exceeds the adjusted value within the start
delay time, the device switches off its output contact immediately. This
Protection is active in all program modes. After a switch off of a current
sudden swtich off alarm, while automatic reset is selected, if the current value
returns to the normal value or to zero value then switch on occurs after a
proper period (T-on). If manual reset is selected, the switch off will continue
until the operator pushes the reset button. Pressing the set button for 3
seconds resets the device.
2.6 Asymmetric Current Protection:
It can be set by the user between %5 and %50. Works on motor Protection
and full protection (Pgr2 and Pgr3) only. 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 ishigh. 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. After a switch off of a asymmetric current alarm, while
automatic reset is selected, if the current value returns to the normal value or
to zero value then switch on occurs after a proper period (T-on). If manual
reset is selected, the switch off will continue until the operator
pushes the reset button. Pressing the set button for
3 seconds resets the device.
1. General
Works as taking samples from three current and voltage phases and shows
these electrical amplitudes on its screen. The user has the opportunity for
selecting type protect a system or a motor, also the user can select to reset
automatically or manually.
When automatic reset is selected, the system will automatically switch on the
contacts after the failure is over. When manual reset is selected, the system
will not switch on its contacts until the operator resets it.
1.1 Protection Programs
1.1.1 System Protection: Prog 1
Protects the system it is connected to from over voltage, under voltage,
asymmetric voltage and over current. The sudden switch off (Iset x .5) is
active. It can be used in electric distribution panels for protection. On this
mode, under current, asymmetric current protections and start delay time are
unfunctional.
1.1.2 Motor Protection : Prog 2
Protects a motor from over voltage, under voltage, asymmetric voltage, over
current and asymmetric current. The sudden switch off (Iset x .5) is active.
To avoid the effects of inrush currents the device has a start delay. On this
mode, only under current is unfunctional.
1.1.3 Full Protection : Prog 3
Protects a system from over voltage, under voltage, asymmetric voltage,
over current, under current and asymmetric current. The sudden switch off
(Iset x .5) is active, and the system has start delay.

1.2 The Use Of The Alarms
User can disable any alarm he does not want to use. To do that he must access
the alarms from the menu and disable them. The disabled alarms will not affect
the relay's function (switch on or off). When one of the disabled alarms occurs,
only the related alarm led will blink to alert the operator.
The active alarms will keep controlling the output contacts.
The thing that must be awared of is that when all alarms are disabled the system
will be unprotected and the output contacts will be always on.

2.7 Under Current Protection:
It can be set by the user between x 0. and
x of the current transformer value.
It works only on full protection mode (Prg2).
When the current of the protected motor
goes below the adjusted value it switches
off its output contact after t2 delay.
It goes active after the start delay ends.
After a switch off of an under current
alarm, while automatic reset is selected, if
the current value returns to the normal value
or zero value then switch on occurs after a
proper period (T-on). If manual reset is
selected, the switch off will continue until
the operator pushes the reset button.
Pressing the set button for 3 seconds
resets the device.
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.
Otherwise, (LinE ovEr Eror) message will
appear on the screen and the output
contact will be switched off. In this case
you should chec the over and the under
current set values.

3. Pass ord Inquiry and Menu Entry
3.1 Pass ord Inquiry
If you push the SET button, the password inquiry menu shows up. Using the
direction buttons, the authorized operator can increase or decrease the digit
value to reach the required value, then pushes SET button to move to the next
digit. After inputing the last digit, pushing the SET button approves the
password. The “ - “ on the middle screen makes the digit follow up easier. This
way the user knows how many digits he already input.
After the password approval, the user gets “Accepted” or “Rejected” message on
the screen for 3 seconds. After that the program main menu shows up, In case
of wrong password entry, the user can move through the menu but can not make
any changes in the program settings.
Pushing the down button shows the menus under the main menu that are in
order:protection program selection, alarm control menu, current setting menu,
voltage settings menu, reset settings menu, power on timing settings,
password menu, failure lock timing settings (in the automatic mode), failue
lock counter settings (in the automatic mode), and factory settings.
Vie ing Menus:
Because the device is password protected, in case of wrong password entry,
the password and the factory settings menus are not shown, the other menus
are shown but not changeable. Only correct password entry shows all menus
and gives the abilitiy of changing the device settigs.
Buttons Use:
The user can move through the menus using the direction buttons (up – down).
When he reaches the required settings he gains access to change the setting
by pressing the SET button, the shown value then blinks. Uses the direction
buttons to change the values, and pushes the SET button again to store the
changes. The blinking values stops blinking then. The user can go to the upper
menu seeking the quit command using the direction buttons and then pushing
the SET button.

ALr/CtrL :
Alarms can be activated or deactivated in this menu and it is related to the
output relay. For example; the occurance of an activated alarm switches off
the output relay, with the related alam led blinking. If a deactivated alarm
occures, the output relay does not switch off the output relay, only the related
alarm led blinks.for this reason the operator must carefully which alarms would
be avtivated and which would be deactivated. In automatic mode, when the
alarm count reach the limit value within the specified period, the system will be
locked and the related alarm led and current or voltage led (maybe both) blink.
To know which alarm occurred operator should use the direction buttons to
reach the related alarm (current, voltage or maybe both) and observe the
failure phase.
Resetting The A arm:
While functioning in the manual mode, if an alarm occurs (an activated alarm)
then the relay switches off the output contact with the related alarm led
blinking. To reset the device the operator must push the SET button until the
reset led goes off. The thing that must be awared of is that if the opeator
releases the set button before the reset button turns off accidently, the main
menu entry shows on, the operator has two options then; the first option is to
enter the password (no matter the entry is wrong or correct) the use the
direction buttons to reach the quit command and press SET button, the second
option is to wait for four minutes without pushing any button.If the related
alarm led turns off again after a long push of the SET button, it means that the
alarm situation is still present.In automatic mode, if the alarm count reaches
the limit value within the specified period, the system will be blockedas it does
in the manual mode. After fixing the problem, the operator must push the SET
button to reset the device.
Aust :
When the over current alarm's (Aust) value is ( ) it is active, when (0) it is
not active. The occurance of an over current alarm while Aust is activated
switches off the output relay. When Aust is deactivated it does not control
the output relay, it only makes the related alarm led blinks.
AaLt :
When the under current alarm's (AaLt) value is ( ) it is active, when (0) it is
not active. The occurance of an under current alarm while AaLt is activated
switches off the output relay. When AaLt is deactivated it does not control
the output relay, it only makes the related alarm led blinks.
When Prg or Prg2 is selected, the AaLt will not be shpwn on the menu.
AaSy :
When the asymmetric current alarm's (AaSy) value is ( ) it is active, when (0)
it is not active. The occurance of an asymmetric current alarm while AaSy is
activated switches off the output relay. When AaSy
is deactivated it does not control the output relay, it only makes
the related alarm led blinks.When Prg is selected, the AaLt will
not be shown on the menu.
quIt : To exit the menu.
I f the current and voltage output
relays are going to be used
individually the Alr/out Value
should set to “0000”.
The connection way is shown in
the Figure next.
If the current and voltage output
relays are going to be used
together, the Alr/out Value should
set to “000 ”and the Com
terminal must not be used.
Unless both of the voltage and
current failures fixed the output
relays will stay in the switch off
mode. The connection way is

Uust :
When the over voltage alarm's (Uust) value is ( ) it is active, when (0) it is
not active. The occurance of an over voltage alarm while Uust is activated
switches off the output relay. When Uust is deactivated it does not control
the output relay, it only makes the related alarm led blinks.
UaLt :
When the under voltage alarm's (UaLt) value is ( ) it is active, when (0) it is
not active. The occurance of an under voltage alarm while UaLt is activated
switches off the output relay. When UaLt is deactivated it does not control
the output relay, it only makes the related alarm led blinks.
UaSy :
When the asymmetric voltage alarm's (UaSy) value is ( ) it is active, when
(0) it is not active. The occurance of an asymmetric voltage alarm while
UaSy is activated switches off the output relay. When UaSy is deactivated
it does not control the output relay, it only makes the related alarm led
blinks.

3.4 Current Settings Menu:
Curr/SEt : The menu where current
settings are made. The operator must
push the SET button to enter this
menu and can go through the menu
using the direction buttons. To change
a setting, he must push the SET
button, change the value using the
direction buttons and push the set
button again to store the new settings.
The menu's sub parameters are as
follows,
Exit
Ct : The current transformer ratio.
Its value can be input by the operator
between 5/5 A and 0000/5 A. It must
be entered the same as the system's
current transformer ratio.
YOn Lrn: Current transformer
polarity direction learning:
( on – oFF)
If it is “ on ” then the device would
learn the direction automatically. If
the device mounted in new panel or
the polarity somehow changed then
it learns the new direction. If off
then the device would learn the
direction once and never learn it
again. Off position is required for
some loads. If there would be a
problem in the current transformer
direction then the current transformer
inputs should be switched.
oSEt : Over current switch off value.
It can be set between Ct x 0. and
Ct x .when the current value
exceeds this value the switch off
occures after t2 delay time.
uSEt : Under current switch off
Value. It can be set between Ct x 0.
and Ct x .This option is only
avaliable on Pgr3. when the current
value goes below this value the
switch off occures after t2 delay time.
NOTE: Under current limit must not be
set higher or equal to the over current
limit . Chec section 2.7
hyS : Percentage Hysteresis. It can
be set between 0,03 and 0,50. It is
used for oSEt and uSEt both.
Cuur/USt:Excessive switch off
current multiplier. It can be set
between oSEt x 2 and oSEt x 0.
When the current value exceeds the
adjusted value the switch off occures
immediately without waiting any delay.
t-1 : Start delay time. It can be set
between and 60 seconds.It is not
used in Pgr .
It is used to prevent the switch off
from occurance because of the
motor's inrush current. Its value will
be reset after each time the current
goes to zero.
Within this period, the Excessive
current multiplier, asymmetric current,
over and under voltage are active.
Only over and undervoltage alarms
are deactivated.
t-2 : Over and under current delay.
It can be set between and 30
seconds. After this period the switch
off occurs if over or under current
alarms occure.
Asy/Curr : Percentage asymmetric
current. It can be set between % 5
and % 50. If the unbalance between
the phases' current exceeds the
adjusted value the switch off occures
after t4 delay.
t-4 : asymmetric current delay. It can
be set between and 30 seconds.
When asymmetric current occures
the switch off occures after this
period.
