2 The SETPOINTS key allows the user to examine and change all the user-programmable setpoints
in the pages of setpoint data as described in the SETPOINTS MODE section. Pressing this key will
cause this message to appear, also indicating the first line of page one of the Setpoints mode:

SETPOINTS
USER LEVEL

3,4 These keys allow the user to view the previous or next line of the current page, as indicated by the
arrow pointing up or down respectively. If either key is held pressed for more than two seconds then
the next or previous lines will be displayed at a fast rate. If the display already shows the last line of
any page then pressing the LINE DOWN key will cause the following message to be displayed:

END OF PAGE

5 The PAGE key allows the user to move from any line in a page to the first line in the next page. For
example, if you are currently viewing any line in page 2 of the Actual Values mode, pressing this key
will cause the display to move to the first line of page 3, Actual Values. If this key is pressed on the
last page of either Actual Values or Setpoints then the display will move to the first page of that
section. As with the LINE keys, holding down the PAGE key will cause the pages to be displayed
rapidly.

6 The STORE key is used to store all new setpoints in the 565/575 Relay’s memory. When this key is
pressed, the value being displayed will be stored as a new setpoint in the relay’s memory and the
following message will appear for 2 seconds (provided the Access jumper is installed):

NEW SETPOINT
STORED

The numeric keypad or the NEXT CHOICE keys are used to display the correct value as seen later.
The STORE key can only be used to store data within the ranges accepted by the 565/575 Relay.
It is also used to set the default display in actual values as described in the Actual Values Mode
section of this manual.

7 The RESET key returns the trip or any latched output relay to its inactive state and extinguishes the
associated LED after a fault condition has caused it to become active. This key will only be effective
if the fault condition has been removed. Otherwise, resetting will not be possible and pressing the
key will result in one the following messages:

8 The HELP key provides the user with information on the function and use of each key on the keypad.
It also provides information about the currently displayed actual values or setpoints message. If
information is needed on the use of any of the keys on the keypad, use the LINE UP or PAGE key
to display the first line of any page. Then press the HELP key and the following message will appear:

PRESS ANY KEY

OR HELP

The user should then press the key for which instruction is required, for example, the PAGE key. If
information is needed on the previously displayed actual values or setpoints message, press HELP
again.

The HELP key can also be pressed on any line of either setpoints or actual values to get information
on that particular setpoint or actual value. If this is done the following message will appear:

PRESS LINE DOWN

TO SCROLL

Pressing LINE DOWN will allow the help message to be viewed. Pressing CLEAR will return the
display to the line where help was requested. Continue pressing LINE DOWN to display the entire
help message.

9 The CLEAR key performs two functions.

1. In the setpoints mode, pressing this key will return an altered unstored setpoint to its original
value. This might be used if you keyed in an incorrect value and had not yet stored it. Once a
value is stored it cannot be altered using the CLEAR key.

2. In the Help mode the key allows the user to return to the previous display mode as described in
number 8.

10 This key, which also functions as the decimal point key is used to view a list of items which cannot
be shown on the display at once. Pressing the NEXT CHOICE key once will cause the first item from
the list to be displayed, pressing it again will display the second item, and so on. When the last item
is reached pressing the key will cause the first item to be displayed again. The entire list can thus
be viewed as many times as needed. The following example shows the use of the NEXT CHOICE
key.

For example, in Setpoints Mode page 3, the ground protection curve is chosen from a list of 5
curves. When this line is first read it will display the curve in use, the Extremely Inverse curve being
shown below.

GND O/C CURVE

SHAPE: EXTREM INV

To advise the user that the NEXT CHOICE key may be used to display other curves, the bottom line
of this display will change for two seconds, and the following display will be seen:

The display will then return to displaying the Extremely Inverse curve. The other curves can now be
viewed one at a time by pressing the NEXT CHOICE key. For example, the Custom Curve will be
seen the next time the key is pressed as shown in the following display.

GND O/C CURVE

SHAPE: CUSTOM

The remaining curves can be viewed in the same way. The display will cycle through all the curves
as the key is pressed. Note that the curve in use by the 565/575 Relay will not be changed by
displaying the various choices. To change the curve in use, it must be displayed and stored. See the
STORE key description.

11 The Numeric keypad has the numbers 0 to 9 and the decimal point. These keys are used to enter
the numerical values of the various setpoints with or without a decimal. The decimal point key also
functions as the NEXT CHOICE key. In this case it is used to display one choice at a time from a list
of items. See NEXT CHOICE key description.

12 The Trip LED indicates the state of the trip output relay which is used to trip the Feeder Breaker
monitored by the 565/575 Relay. When the LED is on, the Trip relay is active with the cause of the
trip condition shown on the LCD display. A flashing LED indicates that the relay was active, and has
returned to its inactive state. This can occur when the fault condition disappears and the relay is
programmed as pulsed. The LED will be extinguished by pressing the RESET key only if the fault
condition causing the relay to be activated has been removed.

13 The Aux 1 LED indicates the state of the output relay, Aux 1, which can be used for a function
chosen by the user. When the LED is on, the relay is active. If pulsed or unlatched operation is
chosen for this relay, the LED will flash if a trip condition is removed or will be extinguished when the
condition causing an alarm is removed. If latched operation is chosen the RESET key must be
pressed to return the relay to its no fault state and extinguish the LED indicator.

14 The Aux 2 LED indicates the state of the output relay, Aux 2, which can be used for a function
chosen by the user. When the LED is on, the relay is active. If pulsed or unlatched operation is
chosen for this relay, the LED will flash if a trip condition is removed or will be extinguished when the
condition causing an alarm is removed. If latched operation is chosen the RESET key must be
pressed to return the relay to its no fault state and extinguish the LED indicator.

15 The Aux.3 LED indicates the state of the output relay, Aux.3. When the LED is on, as during a trip
coil supervision alarm, the Aux 3 relay is inactive (cold coil).

16 If the Service LED illuminates steadily, the supply voltage may be too low. This LED may come on
momentarily when the 565/575 Relay is powered up. This is normal and does not indicate a fault
condition.

17 The Breaker Closed LED indicates the status of the Feeder Breaker being monitored by the 565/
575 Relay. The LED is on if the Feeder Breaker is closed.

18 The Breaker Open LED indicates the status of the Feeder Breaker being monitored by the 565/575
Relay. The LED is on if the Feeder Breaker is open.

 SETPOINTS MODE - PHASE CURRENT
Location Message Line Description

S 2.1 The setpoints page 2 header. In this page you must enter information
SETPOINTS about the phase current transformers being used in your application. This
PHASE CURRENT allows the 565/575 Relay to accurately sense the feeder currents. This
page also allows you to set the levels for various overcurrent alarms and
trips and assign relays to be activated by these.

Each of the four phase currents are sampled at a rate of approximately 960 samples per second.

S 2.2 Enter the primary current rating of the phase current transformers being
PHASE CT RATING used. This value is found on the transformer nameplate. Values can be
PRIMARY 100 A entered in the range of 10 to 5000 Amps, in steps of 5 Amp. If an attempt
is made to enter a value outside this range an OUT OF RANGE error
message will flash. If your transformer has a rating outside this range
contact MULTILIN for information. Note that all three phase CT’s must
have the same rating.

S 2.3 The phase overcurrent pickup level is entered here. This is given as a
PHASE TIMED O/C percentage of the CT rating, in the range of 25% to 250% in steps of 1%.
PICKUP 100 %CT This setting will determine the level of current which the 565 Relay will
identify as too high, and then initiate a timed overcurrent trip of the
breaker, according to the selected curve shape.

For example, if 50% is entered here, then the 565/575 Relay will initiate a
timed trip of the feeder breaker when at least one of the phase currents
reaches 50% of the full CT rating entered in message S 2.2. Determine this
value by referring to the feeder design specifications.

S 2.4 The shape of the required protection curve must be entered here. The
PHASE O/C CURVE curve names are shown below together with the shortened form of the
SHAPE EXTREM INV name which is displayed in this message.

CURVE DISPLAYED
NAME NAME

1. Moderately inverse. MOD INV.

2. Normal Inverse. NORMAL INV.
3. Very Inverse. VERY INV.
4. Extremely Inverse. EXTREM INV.
5. Custom Curve. CUSTOM
6. IEC IEC A
7. IEC IEC B
8. IEC IEC C

Once the correct curve has been chosen for your application, press the
NEXT CHOICE key until the required curve is displayed in message S 2.4
and store the selected curve using the STORE key. The extremely inverse
curve is shown in this example.

Message S 2.5 will not appear if CUSTOM CURVE is selected in message S 2.4.

S 2.5 The phase overcurrent time dial number is entered here. This allows the
PHASE O/C user to fit the selected curve to the system requirements. Any of the 32

LA DISABLED

Messages S 2.8 to 2.10 will only appear if ENABLED is selected in message S 2.7.

S 2.8 This is the value of current flowing in any phase which will cause the Relay
PHASE O/C ALARM to initiate an alarm. This value is entered as a multiple of the phase timed
LA LEVEL 1.5 X P/U overcurrent pickup level chosen in message S 2.3. Values can be entered
in these ranges:

1). 0.5 to 3 in steps of 0.1.

If a value which is not an exact multiple of 0.1 or 0.5 is entered, the 565
Relay will select the closest number to the value entered, display and use
it. For example, if 1.4 is entered then a value of 1.5 will be displayed and
used by the 565 Relay. Attempting to enter a value outside these ranges
will cause an OUT OF RANGE error message to flash.

Choose alarm values lower than the trip pickup levels by an amount which
will give adequate warning of impending problems. For example a value of
80% of the phase timed overcurrent level might be chosen, and 0.8 would
be entered here. A level of 1 times pickup can be programmed. The LCD
will then indicate when the Relay is operating above pickup.

S 2.9 The value of the timed overcurrent alarm delay is entered here in the range
PHASE O/C ALARM of 1 to 255, in steps of 1 second. The purpose of the time delay is to
LA DELAY 1 SEC prevent alarms due to momentary high currents which occur when large
equipment is switched on or off the feeder. If the current drops below the
alarm setting before the time delay which you select, no alarm will be
initiated.

currents which cannot be tolerated without machine damage.
PHASE HISET INST
For example, if the phase overcurrent pickup level was 100 Amps, and a
TRIPS 3.0 X P/U setting of 5 was chosen here then a current of 500 or higher amps in any

S 2.13 The intentional delay on the phase instantaneous trip is set here in the
PHASE INST TRIP range 0 to 40 cycles in steps of one cycle. If 0 is selected, INST will be

Definite time characteristics can be implemented by using the phase

100 A 5000 in steps of 5 Amp. This value will be on the transformer nameplate.

S 3.5 The ground overcurrent pickup level is entered here as a percentage of the
GROUND TIMED O/C CT rating. The range of values allowed is 5% to 150% in steps of 1%. This
PICKUP 40% CT setpoint sets the level of current at which the 565 Relay initiates a timed
trip of the feeder breaker according to the curve selected in message S
3.6.

For example, if 50% is entered here, then the 565/575 Relay will initiate a
programmed trip of the feeder breaker when the ground current reaches
50% of the full CT rating. The CT rating used will be either:

1) The phase CT primary rating entered in message S 2.2, if residual

current sensing is chosen in message S 3.3.

2) The zero sequence CT primary rating, if zero sequence sensing is

chosen in message S 3.3.

If the ground current exceeds the limits of the Time/Overcurrent curve in

use, a feeder breaker trip will occur. Determine the ground current pickup
level for your application according to the grounding system used.

SETPOINTS are set up to suit the particular application. These switch inputs are
CONFIGURATION provided on the 565 Relay back panel to accept external signals for
customer use. The use of switches 1 to 8 is user definable. External
switches can have either normally open (N.O) or normally closed (N.C)
contacts. A normally open switch will have its contacts in the open (non-
conducting) state under inactive conditions. Similarly, a normally closed
switch will have its contacts closed (conducting) in the inactive state. This
information must be given to the 565 Relay if it is to use these inputs. Other
features such as the time and date are also setup on this page.

S 4.2 The current time must be entered here in the following format:

This time setting will not be lost if power supply to the 565 Relay is
interrupted, because a lithium battery maintains the real time clock.

S 4.3 The current date must be entered in this message. The Relay will use this
SET mm/dd/yy to keep a record of when trips occurred. The date setting is laid out in the

AUX 1 RELAY Pulsed Operation

(575)
PULSED
If pulsed operation is selected, the Trip relay is energized and the pulse
timer is initiated upon a trip declaration. If the fault current drops below pick
up before the pulse timer expires, this is taken as an indication that the
breaker has opened successfully. In this case, the Trip relay will become
de-energized when the pulse time does expire. Note that this pulse time,
which is programmed in message S4.30, will be the minimum amount of
time that the Trip relay will remain energized. On the other hand, if the
pulse timer expires before the fault current drops below pick up, the relay
will remain energized. When the fault current eventually drops below pick
up, the 565 seal-in timer is initiated. After this 2.5 - 3.5 cycle seal-in delay
elapses, the Trip relay de-energizes.

NOTE: The 565 relays are not designed to regularly break inductive
current. Pulsed relay becomes latched to act as the seal-in

programmed to Trip & Aux. 1.

S 4.30 As with the Aux. 1 relay, this setpoint allows the mode of operation for the
AUX 2 RELAY Aux. 2 relay to be selected. The available modes are pulsed, latched or

S 4.31 This setpoint allows the user to select the mode of operation for the Aux 1
AUX 1 RELAY relay. The available modes are pulsed, latched, or unlatched. If the Aux 1
UNLATCHED relay is programmed as pulsed, only trip conditions should be assigned to
(565)
it. When programmed in this pulsed mode, Aux 1 is intended to be used as
a trip follower. Alarm conditions assigned to a pulsed Aux 1 will only reset
if the breaker is open.

Pulsed Operation

If pulsed operation is selected, the Aux 1 relay is energized and the pulse
timer is initiated upon a trip/alarm declaration. In order for the 565 to
determine that the breaker has opened successfully, two conditions must
be met. First, the fault current must be below pick up. Secondly, either the
52a contact must be detected as open or the 52b contact must be
detected as closed. When this happens before the pulse timer expires, the
Aux 1 relay will become de-energized when the pulse time does expire.
Note that this pulse time which is programmed in message S4.32 will be
the minimum amount of time that the trip relay will remain energized. On
the other hand, if the pulse timer expires before the fault current drops
below pick up and the 52a/52b contacts respond, the relay will remain
energized. When these two conditions eventually occur, the 565 seal-in
timer is initiated. After this 2.5 - 3.5 cycle seal-in delay elapses, the Aux 1
relay de-energizes.

UNLATCHED relay does not look at the 52a/52b contacts. If the Aux 2 relay is
programmed as pulsed, only alarm conditions should be assigned to
it.

Pulsed Operation

If pulsed operation is selected and a fault condition develops, the Aux 2

relay is energized and de-energized repeatedly. The rate at which the Aux
2 relay toggles is determined by the Aux 2 relay pulse timer setpoint S 4.34.
Only when the fault current drops below pick up will Aux 2 relay stop
pulsating.

S 5.7 The 565 Relay has the ability to accept an analog input signal in the range
MIN CURR SCALE of 4-20 mA and this display asks for the scale factor which you intend to
LA VALUE: 4.00 use for the minimum analog input.

The quantity being monitored might be the temperature of a transformer

on the feeder. This input can be used to initiate alarms if it exceeds safe
levels. A scale factor can be chosen to change the displayed value from
milliamps to degrees centigrade. The use of the minimum scale factor is
shown by the following example. The 565 Relay logic is configured so that
the value which you will see displayed when the analog signal is 4 mA will
be the scale factor minimum value. Refer to the manufacturer’s instruc-
tions for the monitor or device to determine the temperature (or other
quantity) corresponding to its 4 mA output.

If this value is 50 degrees centigrade, for example, then set the minimum
scale factor at 50. Now when a 4 mA input is presented to the 565 Relay it
will display 50 indicating a temperature, which is more useful than a
milliamp reading.

The range of possible values for the minimum scale factor is 0 to 1023 in

S 5.8 This display asks for the scale factor which you intend to use for the
MAX CURR SCALE maximum analog input. In a similar way to the minimum scale factor, the
LA VALUE: 20.00 maximum scale factor is used to set the value which will be displayed when
the analog signal into the relay is 20 mA. Again, refer to the manufacturer’s
instructions for the monitor or device which you intend to use to determine
the magnitude of the temperature (or other quantity) corresponding to its
20 mA output. Set the maximum scale value to this figure. Now, when a 20
mA input is presented to the 565 Relay it will display this figure, indicating
a temperature for example, rather than a mA reading. The range of
possible values for the maximum scale factor is 0 to 1023 in steps of 0.01.

Once the minimum and maximum scale factors are set the 565 Relay logic

S 9.2 This message asks for the type of voltage transformer sensing which you
VT CONNECTION intend to use. There are three possible systems, as shown in wiring Figure
WYE 2.6. The choices for the setpoint are:

1. Wye.
2. Open Delta.
3. Delta/Wye
4. None

The Delta/Wye choice allows the 565/575 to measure secondary voltages

wired as Wye and display them as phase to phase quantities on the
primary side of a Delta/Wye connected transformer. Hence, selecting
Delta/Wye does not multiply the result by √3. For example:

In a 2.4 kV:120 V PT system (i.e. 120 V into the relay), WYE displays 2.4 kV
A-N, DELTA/WYE displays 2.4 kV A-B, NOT 2.4 kV × √3.

If none is selected, voltage sensing will be disabled.

Refer to your system specifications or one line diagram to determine which

your system is. Use the NEXT CHOICE key to select the appropriate one
and press the STORE Key to save the new value.

Only message S 9.21 will appear if the VT connection is selected as NONE in message S 9.2.

S 9.3 The voltage transformer which you are using to sense voltage may operate
VT NOMINAL SEC at various secondary voltages depending on the sensing system used.
VOLTS 120 VOLTS
The 565/575 has the ability to be programmed for the desired secondary
rating, which should be the rated secondary voltage stamped on the
transformer’s nameplate. This will be the phase to neutral voltage for a Wye
system, or a phase to phase voltage for an Open Delta system. The range
is from 48 to 240 V in steps of 0.1 V.

S 9.4 The primary voltage of the VT which monitors the feeder is entered here.
VT PRIMARY VOLTS This is the “nameplate” primary voltage. The voltage transformer primary
1.20 kV rating range is from 0.10 to 69 kV in steps of 0.01 kV.

S 9.5 When enabled, this setpoint allows undervoltage alarms and trips to occur
ZERO VOLTS with the 565/575 reading all phase voltages as zero. For the 565/575, zero
DETECT ENABLED is when the voltage is below 48% of the nominal rating. When disabled, all
phases reading below 48% are considered a normal no voltage condition.
Thus, no alarms or trips will be declared. As always, undervoltage trips

DISABLED stay below the trip setpoint for the selected time delay. NOTE: When an
undervoltage condition is present the reclosure scheme will not issue a
close command to the breaker. When the undervoltage condition is no
longer present, the breaker should be closed manually.

Messages S 9.7 to S 9.9 will only appear if ENABLED is selected in message S 9.6.

S 9.7 The undervoltage trip level is entered here as a percentage of the VT

UNDERVOLT TRIP rating. Feeder undervoltage protection is necessary because a significant
LEVEL 80 %VT drop in feeder voltage indicates a system fault.

The 565/575 Relay monitors the phase voltages while the breaker is
closed and provides a trip signal if the level drops to the value which you
enter here. The range of possible settings for the undervoltage setpoint is
50% to 100% of the VT rating in steps of 1%. Refer to Table 2.1 to
determine how many phases must be below the trip level to cause a trip for
the VT connection being used.

S 9.8 The delay on the undervoltage trip is entered here, in the range of 0.1 to
UNDERVOLT TRIP 25.5 seconds in steps of 0.1 seconds. This prevents nuisance trips caused

Overcurrent Protection Alternately, the custom curve can be used to match the
system requirements very closely.
The 565/575 Relay continuously monitors the three phase
currents and ground current in the feeder through its CT’s and CAUTION

Failure to ensure the maximum current vs. delay can cause
The 565/575 Relay allows the following curves to be chosen: damage to the relay which may result in loss of relay
protection.

Use of Standard Curves

If it is intended to use the standard curves, for overcurrent
protection, then the curve shape and number must be deter-
mined and entered into the 565/575 Relay. For each shape,
there are 32 different curves corresponding to a different time
dial. The selection of protection curve shape, pick-ups and
time dial must be determined from a system co-ordination
study. To determine the curve shape and number most suited
to your system proceed as follows:

Plot the time/overcurrent characteristics of all the related

system equipment to the feeder on a blank log/log sheet.
Alternately only the most critical items may be plotted. This is
called the System Plot.

Now choose an overcurrent value on the system plot, prefer-

ably the one which is most critical to the device being pro-
tected. Next select the standard curve shape which most
closely matches the time/overcurrent characteristics of the
item to be protected. Finally, the curve number must be
selected to position this curve in the correct vertical location.

The standard curves which are programmed into the 565/575

relay are shown in Figure 7.1 through Figure 7.8.

Use of Custom Curve

In addition to the standard curves, the 565/575 Relay also
has a user-programmable curve. This curve can be defined by
the user and thus be closely matched to the needs of the
particular application. This is a vast improvement on conven-
tional feeder protection devices which forced the user to
compromise on protection by using a standard curve which
might not exactly match the protection requirements of the
particular system.

Power Loss Check

This can be done when the above checks have been com-
pleted. First, make a note of any setpoint and then with power
applied, trip the Relay on any fault. For example this can be
done by simply increasing the injected current to simulate a
ground overcurrent and waiting for the timed overcurrent
curve to come into operation. When the trip relay or other
assigned relay is activated and the associated LED illumi-
nated, remove all power and current from the 565/575 Relay.
Leave it in this condition for a short time, say one minute.

Restore power and verify that the fault indication remains, ie,
the LED on the front panel remains illuminated. Select set-
points mode and view the earlier noted message. Verify that
the relay still displays the same value. This verifies that trip
annunciations and setpoints are unaffected by loss of power.

Enable all functions which were disabled for these tests.

Return the injected current to zero and return all setpoints to
their original values. Finally, remove the access jumper or
open the keyswitch. Remove all test apparatus and return
the system wiring to nor mal.

3. Check breaker position. Due to applications where
the potential transformers are located on the local
side of the breaker, the 565/575 must see the
breaker closed at terminals 9, 10, and 11 before
issuing an undervoltage trip. This prevents the
relay from issuing an undervoltage trip each time
the breaker is opened.

Functioning in series with the hardware access

jumper is the relay’s Setpoint Access/Software
Code setpoint that is only visible when the Secu-
rity Feature setpoint is enabled. When the 565/
575 is shipped from the factory, the Setpoint
Access/Software Code setpoint is enabled and
the Security Feature is disabled. Therefore, you
cannot see the Setpoint Access/Software Code
setpoint and only the hardware jumper at termi-
nals 33 and 34 will determine whether you can
store setpoints.

If you now establish communications with a 565/

575 using Relaycom®, the Setpoint Access/Soft-
ware Code setpoint can be disabled independent
of the Security Feature setpoint. Relaycom® calls
this “Local Setpoint Access.” Suppose one disa-
bled “Local Setpoint Access” using Relaycom®.
The next time one tries to store a new setpoint
using the 565/575 keypad, they will get the “Illegal
Access” message even though the access jumper
is in place. This will cause confusion because the
Security Feature is disabled and this normally
means the Setpoint Access/Software Code set-
point is enabled.

This is not the case. The Setpoint Access/Soft-

ware Code setpoint is disabled and you cannot
view it because the Security Feature setpoint is
also disabled. To make matters worse, you cannot
enable the Security Feature setpoint to allow you
to enable the Setpoint Access/Software Code
setpoint. Setpoint access is disabled. The only
way to re-establish setpoint access is to enable
“Local Setpoint Access” in Relaycom®.
