Starting up

Section 2 Starting up

2.1 Factory and site acceptance testing

Testing the proper IED operation is carried out at different occasions.

• Acceptance testing
• Commissioning testing
• Maintenance testing

This manual describes the workflow and the steps to carry out the commissioning
testing.

Factory acceptance testing (FAT) is typically done to verify that the IED and its
corresponding configuration meet the requirements of the utility or industry. This
test is the most complex and in depth, as it is done to familiarize the user with a
new product or to verify a new configuration. The complexity of this testing
depends on several factors.
• New IED type
• New configuration
• Modified configuration

Site acceptance testing (SAT or commissioning testing) is typically done to verify

that the installed IED is correctly set and connected to the power system. SAT
requires that the acceptance testing has been performed and that the application
configuration is verified.

Maintenance testing is a periodic verification that the IED is healthy and has
correct settings, depending on changes in the power system. There are also other
types of maintenance testing.

2.2 Commissioning checklist

Before starting up commissioning at site, the following items should be available.

• Single line diagram

• Protection block diagram
• Circuit diagram
• Setting list and configuration
• RJ-45 Ethernet cable (CAT 5)
• Three-phase test kit or other test equipment depending on the complexity of
the configuration and functions to be tested.
630 series 11
Commissioning Manual
Section 2 1MRS756801 D
Starting up

• PC with PCM600 installed along with the connectivity packages

corresponding to the IEDs to be tested.
• Administration rights on the PC, to set up IP addresses
• Product documentation (engineering manual, installation manual,
commissioning manual, operation manual, technical manual and
communication protocol manual)

2.3 Checking of the power supply

Check that the auxiliary supply voltage remains within the permissible input
voltage range under all operating conditions. Check that the polarity is correct
before powering the IED.

2.4 Energizing the IED

2.4.1 Checking the IED operation

Check all connections to external circuitry to ensure correct installation, before
energizing the IED and carrying out the commissioning procedures.

• Energize the power supply of the IED to start it up. This can be done in a
number of ways, from energizing a whole cubicle to energizing a single IED.
• Set the IED time if no time synchronization source is configured.
• Check the self-supervision function via the LHMI path Main menu/
Monitoring/IED status or Main menu/Monitoring/Internal events to verify
that the IED operates properly.

2.4.2 IED startup sequence

The following sequence is expected when the IED is energized.

• The green Ready LED starts flashing instantly and the ABB logo is shown on
the LCD.
• After approximately 30 seconds, "Starting" is shown on the LCD.
• Within 90 seconds, the main menu is shown on the LCD and the green Ready
LED shows a steady light, which indicates a successful startup.

The startup time depends on the size of the application

configuration. Application configurations with less functionality
have shorter startup times.

12 630 series
Commissioning Manual
1MRS756801 D Section 2
Starting up

If the green Ready LED continues to flash after the startup, the IED has detected an
internal error. Navigate via Main menu/Monitoring/IED status to investigate the
error description.

2.5 Setting up communication between PCM600 and

the IED

The communication between the IED and PCM600 is independent of the used
communication protocol within the substation or to the NCC.

The communication media is always Ethernet and the used protocol is TCP/IP.

Each IED has an Ethernet interface connector on the front and on the rear side.
Both Ethernet connectors can be used for communication with PCM600.

When an Ethernet-based station protocol is used, PCM600 communication can use

the same Ethernet port and IP address.

For the connection of PCM600 to the IED, two basic variants have to be considered.
• Direct point-to-point link between PCM600 and the IED front port.
• Indirect link via a station LAN or from remote via a network.

The physical connection and the IP address must be configured in both cases to
enable communication.

The communication procedures are the same in both cases.

1. If needed, set the IP address for the IEDs.
2. Set up the PC or workstation for a direct link (point-to-point), or
3. Connect the PC or workstation to the LAN/WAN network.
4. Configure the IED IP addresses in the PCM600 project for each IED to match
the IP addresses of the physical IEDs.

Setting up IP addresses
The IP address and the corresponding mask can be set via the LHMI for each
available Ethernet interface in the IED. Each Ethernet interface has a default
factory IP address when the complete IED is delivered.

• The default IP address for the IED front port is 192.168.0.254 and the
corresponding subnetwork mask is 255.255.255.0, which can be set via the
local HMI path Main menu/Configuration/Communication/TCP-IP
configuration/Front port.
• The default IP address for the IED rear port is 192.168.2.10 and the
corresponding subnetwork mask is 255.255.255.0, which can be set via the
local HMI path Main menu/Configuration/Communication/TCP-IP
configuration/LAN1.

630 series 13
Commissioning Manual
Section 2 1MRS756801 D
Starting up

The front and rear port IP addresses cannot belong to the same
subnet or communication will fail. It is recommended to change the
IP address of the front port if the front and rear port are set to the
same subnet.

Setting up the point-to-point access to IEDs front port

The IED front port is a standard Ethernet interface with DHCP server functionality.
When a PC is connected to the front port, the DHCP server automatically assigns
the IP address from the same subnetwork.

See the operating system manual for details on how to obtain the IP
address automatically.
1. Connect the PC network adapter to the IED front port.
2. Wait until the operating system automatically acquires the
network address.
3. Check that the front port connector green status LED is lit.
4. Ping the IED to verify that the connection is correctly
established. The default IP address of the front port is
192.168.0.254.

Use Ethernet crossover cables only for point-to-point connections.

Modern network adapters contain logic for automatic detection if
they are connected directly to another network adapter using a
regular Ethernet cable.

Setting up the PC to access the IED via a network

This task depends on the used LAN/WAN network. The PC and the IED must
belong to the same subnetwork.

2.6 Writing an application configuration to the IED

Ensure that the IED includes the correct application configuration

according to project specifications.

• Create the application configuration using PCM600 and then write it to the
IED.
• Establish a connection between PCM600 and the IED when an application
configuration must be written to the IED.

14 630 series
Commissioning Manual
1MRS756801 D Section 2
Starting up

After writing an application configuration to the IED, the IED makes an

application restart or a complete IED restart, when necessary.

Be sure to set the correct technical key in both the IED and
PCM600 to prevent writing an application configuration to a wrong
IED.

See the engineering manual for information on how to create or

modify an application configuration and how to write to the IED.

2.7 Checking CT circuits

Check that the wiring is in strict accordance with the supplied

connection diagram.

The CTs must be connected in accordance with the terminal diagram provided with
the IED, both with regards to phases and polarity. The following tests are
recommended for every primary CT or CT core connected to the IED.

• Primary injection test to verify the current ratio of the CT, the correct wiring
up to the protection IED and correct phase sequence connection (that is L1,
L2, L3.)
• Polarity check to prove that the predicted direction of the secondary current
flow is correct for a given direction of the primary current flow. This is an
essential test for the proper operation of the directional function, protection or
measurement in the IED.
• CT secondary loop resistance measurement to confirm that the current
transformer secondary loop DC resistance is within specification and that there
are no high resistance joints in the CT winding or wiring.
• CT excitation test to ensure that the correct core in the CT is connected to the
IED. Normally only a few points along the excitation curve are checked to
ensure that there are no wiring errors in the system, for example, due to a
mistake in connecting the CT's measurement core to the IED.
• Earthing check of the individual CT secondary circuits to verify that each three-
phase set of main CTs is properly connected to the station earth and only at
one electrical point.
• Insulation resistance check.

CT and VT connectors are pre-coded, and the CT and VT connector

markings are different. For more information, see the installation
manual.

630 series 15
Commissioning Manual
Section 2 1MRS756801 D
Starting up

Both the primary and the secondary sides must be disconnected

from the line and the IED when plotting the excitation characteristics.

2.8 Checking VT circuits

Check that the wiring is in strict accordance with the supplied connection diagram.

Correct possible errors before continuing to test the circuitry.

Test the circuitry.

• Polarity check
• VT circuit voltage measurement (primary injection test)
• Earthing check
• Phase relationship
• Insulation resistance check

The polarity check verifies the integrity of circuits and the phase relationships. The
polarity must be measured as close to the IED as possible to ensure that most of the
wiring is also checked.

The primary injection test verifies the VT ratio and the wiring all the way from the
primary system to the IED. Injection must be performed for each phase-to-neutral
circuit and each phase-to-phase pair. In each case, voltages in all phases and
neutral are measured.

2.9 Checking the RTXP test switch

The RTXP test switch is designed to provide the means of safe testing of the IED.
This is achieved by the electromechanical design of the test switch and test plug
handle. When the test plug handle is inserted, it first blocks the trip and alarm
circuits then it short circuits the CT secondary circuit and opens the VT secondary
circuits making the IED available for secondary injection.

When pulled out, the test handle is mechanically stopped in half withdrawn
position. In this position, the current and voltage enter the protection, but the alarm
and trip circuits are still isolated. Before removing the test handle, check that no
trip or alarms are present in the IED.

The trip and alarm circuits are not restored for operation until the test handle is
completely removed.

Establishing connection and verifying the station communication

Section 3 Establishing connection and verifying the

station communication

3.1 Setting the station communication

IEC 61850 communication is always included in 630 series IEDs and it is enabled
by default. IEC 61850 communication configuration is done using IET600 and
PCM600.

Based on ordering and licensing either DNP3 or IEC 60870-5-103 can be included
in addition to IEC 61850. Mapping data points to DNP3 protocol is done using
Communication Management in PCM600, and mapping data points to IEC
60870-5-103 protocol is done using Application Configuration in PCM600.

• To enable or disable a station protocol, set the parameter Operation to "On" or

"Off" in Main menu/Configuration/Communication.
• IEC 61850 GOOSE receive functions are disabled by default. Set the
parameter Operation to "On" or "Off" in Main menu/Configuration/
Communication/1:IEC61850-8-1/GOOSE.

3.2 Verifying the communication

The station communication status is shown in Main menu/Monitoring/IED status.

The IEC 60870-5-103 communication status is not available in the

IED status menu.

If the station control system is not available for verifying the communication, then
separate testing or diagnostics tools made for the specific protocol must be used.

For example, for IEC 61850 communication, ABB provides Integrated Testing
Tool ITT600 SA Explorer. It is designed for easy on-line diagnosis and
troubleshooting of IEC 61850 based substation automation systems.

Testing IED operation

Section 4 Testing IED operation

4.1 Preparing the IED to verify settings

• If a test switch is included, start preparation by making the necessary

connections to the test switch. This means connecting the test equipment
according to a specific and designated IED terminal diagram.
• Put the IED into the test mode to facilitate the test of individual functions and
prevent unwanted operation caused by other functions. The test switch should
then be connected to the IED.
• Verify that analog input signals from the analog input module are measured
and recorded correctly by injecting currents and voltages required by the
specific IED.
• To make testing even more effective, use PCM600. PCM600 includes the
Signal monitoring tool, which is useful in reading the individual currents and
voltages, their amplitudes and phase angles. In addition, PCM600 contains the
Disturbance handling tool. The content of reports generated by the Disturbance
handling tool can be configured which makes the work more efficient. For
example, the tool may be configured to only show time tagged events and to
exclude analog information and so on.
• Check the disturbance report settings to ensure that the indications are correct.
• For test functions and test and signal parameter names, see the technical
manual. The correct initiation of the disturbance recorder is made on start and/
or release or trip from a function. Also check that the wanted recordings of
analogue (real and calculated) and binary signals are achieved.

Parameters can be entered into different setting groups. Make

sure to test functions for the same parameter setting group. If
needed, repeat the tests for all different setting groups used.
The difference between testing the first parameter setting group
and the remaining is that there is no need for testing the
connections.

• During testing, observe that the right testing method, that corresponds to the
actual parameters set in the activated parameter setting group, is used.
• Set and configure the functions before testing.
Most functions are highly flexible and permit a choice of functional and
tripping modes. The various modes are checked at the factory as part of the
design verification. In certain cases, only modes with a high probability of
coming into operation need to be checked when commissioned to verify the
configuration and settings.
Requirements for testing the function.

630 series 23
Commissioning Manual
Section 4 1MRS756801 D
Testing IED operation

• Calculated settings
• Valid configuration diagram for the IED
• Valid terminal diagram for the IED
• Technical manual
• Three-phase test equipment
• The test equipment should be able to provide a three-phase supply of currents
and three-phase voltage. The magnitude and angle of currents (and voltages)
should be possible to vary. Check that the IED is prepared for test before
starting the test session. Consider the logic diagram of the function when
performing the test.

The response from a test can be viewed in different ways.

• Binary output signals

• Service values in the LHMI (logical signal or phasors)
• A PC with PCM600 (configuration software) in debug mode

Do not switch off the auxiliary power supply to the IED before the
changes, for example, setting parameter or local/remote control
state changes, are saved.

A mechanism for limiting the number of writings per time period is included in the
IED to prevent the flash memory from wearing out due to too many writings
caused by the application configuration. As a consequence, saving application
function states may take up to an hour. If the auxiliary power is interrupted before
the states are saved, that change is lost. Settings and configuration parameters are
saved without delay.

4.2 Activating the test mode

Put the IED into the test mode before testing. The test mode blocks all protection
functions and some of the control functions in the IED, and the individual functions
to be tested can be unblocked to prevent unwanted operation caused by other
functions. In this way, it is possible to test slower back-up measuring functions
without the interference from faster measuring functions. Test mode is indicated
when the yellow StartLED flashes.

1. Select Main menu/Tests/IED test mode

2. Set parameter TestMode to On.
3. Save the changes.
As a consequence, the yellow startLED starts flashing as a reminder and
remains flashing until the test mode is switched off.

24 630 series
Commissioning Manual
1MRS756801 D Section 4
Testing IED operation

4.3 Preparing the connection to the test equipment

The IED can be equipped with a test switch of type RTXP8, RTXP18 or RTXP24.
The test switch and its associated test plug handle (RTXH8, RTXH18 or RTXH24)
are a part of the COMBITEST system, which provides secure and convenient
testing of the IED.

• When using the COMBITEST, preparations for testing are automatically

carried out in the proper sequence, that is, for example, blocking of tripping
circuits, short circuiting of CT’s, opening of voltage circuits, making IED
terminals available for secondary injection. Terminals 1 and 8, 1 and 18 as
well as 1 and 12 of the test switches RTXP8, RTXP18 and RTXP24
respectively are not disconnected as they supply DC power to the protection IED.
• The RTXH test-plug handle leads may be connected to any type of test
equipment or instrument. When a number of protection IEDs of the same type
are tested, the test-plug handle only needs to be moved from the test switch of
one protection IED to the test switch of the other, without altering the previous
connections.
• Use COMBITEST test system to prevent unwanted tripping when the handle is
withdrawn, since latches on the handle secure it in the half withdrawn position.
In this position, all voltages and currents are restored and any re-energizing
transients are given a chance to decay before the trip circuits are restored.
When the latches are released, the handle can be completely withdrawn from
the test switch, restoring the trip circuits to the protection IED.
• If a test switch is not used, perform measurement according to the provided
circuit diagrams.

Never disconnect the secondary connection of a current transformer

circuit without first short-circuiting the transformer's secondary
winding. Operating a current transformer with the secondary
winding open will cause a massive potential build up that may
damage the transformer and cause personal injury.

4.4 Connecting test equipment to the IED

• Connect the test equipment according to the IED specific connection diagram
and the needed input and output signals for the function under test.
• Connect the current and voltage terminals. Pay attention to the current polarity.
Make sure that the connection of input and output current terminals and the
connection of the residual current conductor is correct. Check that the input
and output logical signals in the logic diagram for the function under test are
connected to the corresponding binary inputs and outputs of the IED under test.

630 series 25
Commissioning Manual
Section 4 1MRS756801 D
Testing IED operation

To ensure correct results, check that the IED as well as the test
equipment are properly earthed before testing.

4.5 Releasing the function to be tested

Release or unblock the function to be tested to ensure that only the function or the
chain of functions to be tested are in operation and that other functions are
prevented from operating. Release the tested function(s) by setting the
corresponding Blocked parameter under Function test modes to “No” in the LHMI.

When testing a function in this blocking feature, not only the actual function but
the whole sequence of interconnected functions (from measuring inputs to binary
output contacts) including logic must be activated. Before starting a new test mode
session, scroll through every function to ensure that only the function to be tested
(and the interconnected ones) have the parameters Blocked and eventually
EvDisable set to “No” and “Yes” respectively. A function is also blocked if the
BLOCK input signal on the corresponding function block is active, which depends
on the configuration. Ensure that the logical status of the BLOCK input signal is
equal to 0 for the function to be tested. Event function blocks can also be
individually blocked to ensure that no events are reported to a remote station
during the test. This is done by setting the parameter EvDisable to “Yes”.

Any function is blocked if the corresponding setting in the LHMI

under Main menu/Tests/Function test modes menu remains “On”,
that is, the parameter Blocked is set to “Yes” and the parameter
TestMode under Main menu/Tests/IED test mode remains active.
All functions that were blocked or released in a previous test mode
session, that is, the parameter Test mode is set to “On”, are reset
when a new test mode session is started.

1. Select Main menu/Tests/Function test modes.

2. Browse to the function instance that needs to be released.
3. Set parameter Blocked for the selected function to “No”.

4.6 Verifying analog primary and secondary

measurement

Verify that the connections are correct and that measuring and scaling is done
correctly. This is done by injecting current and voltage to the IED.

26 630 series
Commissioning Manual
1MRS756801 D Section 4
Testing IED operation

Apply input signals as needed according to the actual hardware and

the application configuration.

1. Inject a symmetrical three-phase voltage and current at rated value.

2. Compare the injected value with the measured values.
The voltage and current phasor menu in the local HMI is located under Main
menu/Measurements.
3. Compare the frequency reading with the set frequency and the direction of the
power.
The frequency and active power are located under Main menu/Monitoring/I/
O status/Monitoring/PWRMMXU(PQf):1. Then navigate to the bottom of
the list to find the frequency.
4. Inject an asymmetrical three-phase voltage and current, to verify that phases
are correctly connected.

If some setting deviates, check the analog input settings under

Main menu/Configuration/Analog inputs
Measured values such as current (phase and residual) and voltages (phase-to-earth,
phase-to-phase and residual) as well as active, reactive and apparent power, power
factor phase angles as well as positive and negative sequence currents and voltages
are available in the local HMI under Main menu/Monitoring/I/O status/
Monitoring.

Navigate to the measurement function that contains the quantity to be checked.

reports on measured values can be exported from the Signal Monitoring tool to
other tools (for example, MS Excel) for further analysis.

5.1.3.1 Checking the communication link operation

There are several different communication links on the product. First check that all
communication ports that are used for communication are turned on.

To check that optical serial port hardware is working, check the

optical fibres for light. Do not look directly into the transmitter
since the direct light can be harmful for the eyes. Point the fibre or
transmitter towards a surface where it is possible to observe when
the light is on. To turn on the transmitter although there is no actual
communication, set revPolarity in Main menu/Configuration/
Communication/IEC60870-5-103/General to "On".

1. Check the front communication port RJ-45.

1.1. Check that the uplink LED is lit with a steady green light.
The uplink LED is located on the LHMI above the RJ-45
communication port on the left. The port is used for direct electrical
communication to a PC connected via a crossed-over Ethernet cable.
1.2. Check the communication status of the front port via the LHMI in Main
menu/Monitoring/Ethernet/Front port.
Check that the LINKUP value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
2. Check the communication status of the rear port X0 via the LHMI in Main
menu/Monitoring/Ethernet/LAN1.
The X0 communication port on the rear side of the IED is for electrical
communication to a PC connected via a crossed-over Ethernet cable. This
communication port is an alternative to the front communication port.
• Check that the LINKUP value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
3. Check the communication status of the rear port X1 via the LHMI in Main
menu/Monitoring/Ethernet/LAN1.
The X1 communication port on the rear side of the IED is for optical Ethernet
via LC connector or electrical via RJ-45 connector of the IEC 61850-8-1
station bus communication.
• Check that the LINKUP value is 1, that is, the communication is
working. When the value is 0, there is no communication link.

5.1.3.2 Checking the time synchronization

• Select Main menu/Monitoring/IED status and check the status of the time
synchronization on Time Synch.
The Time synch value is Ready when the synchronization is in order.

Activate the time synchronization source. Otherwise, the value

is always Ready.

5.1.4 Running the display test

To run the display test, either use the push buttons or start the test via the menu.

• Select Main menu/Test/LED test.

• Press or simultaneously and .
All the LEDs are tested by turning them on simultaneously. The display shows
a set of patterns so that all the pixels are activated. After the test, the display
returns to normal state.

5.2 Indication messages

5.2.1 Internal faults

When the Ready LED indicates an internal fault by flashing, the message
associated with the fault is found in the internal event list in the LHMI menu Main
menu/Monitoring/Internal events. The message includes the date, time,
description and signal state for the fault. The internal event list is not updated
dynamically. The list is updated by leaving the Internal events menu and then
selecting it again. The current status of the internal fault signals can also be
checked via the LHMI in Main menu/Monitoring/IED status.

The ABB logo together with the IED FAILURE message appear on the screen
after a five minutes' communication break between the LHMI and the IED. The
LHMI panel displays the message due to a communication failure or a severe
functional error in the IED. The protection functionality of the device can be
ensured by testing the IRF contact status.

Different actions are taken depending on the severity of the fault. If the fault is
found to be permanent, the IED stays in internal fault mode. The IED continues to
perform internal tests during the fault situation.

When a fault appears, the fault indication message is to be recorded and stated
when requesting support or service.

Troubleshooting

5.3.3.1 Inspecting the wiring

The physical inspection of wiring connections often reveals the wrong connection
for phase currents or voltages. Even when the phase current or voltage connections
to IED terminals are correct, wrong polarity of one or more measurement
transformers can cause problems.

• Check the current or voltage measurements and their phase information from
Main menu/Measurements.
• Check that the phase information and phase shift between phases is correct.
• Correct the wiring if needed.
• Change the parameter ReversePolarity in Configuration/I/O modules/
AIM2 for the channel n (n= the number of the channel that has wrong
polarity).
• In PCM600, change the parameter CTStarPointn (n= the number on the
current input) under the parameter settings for each current input.
• Check the actual state of the connected binary inputs.
• In LHMI, select Main menu/Monitoring/I/O status/Binary input
modules. Then navigate to the board with the actual binary input to be
checked.
• With PCM600, right-click the product and select Signal Monitoring.
Then navigate to the actual I/O board and to the binary input in question.
The activated input signal is indicated with a yellow-lit diode.
• Measure output contacts using the voltage drop method of applying at least the
minimum contact load given for the output relays in the technical data, for
example, 100 mA at 24 V AC/DC.

Output relays, especially power output relays, are designed for

breaking high currents. Due to this, layers of high resistance
may appear on the surface of the contacts. Do not determine
proper functionality of connectivity or contact resistance by
measuring with a regular hand-held ohm meter.

to the actual I/O-board and the binary input in question. The activated
output signal is indicated with a yellow-lit diode. Each BOn_PO is
represented by two signals. The first signal in LHMI is the actual value
“1” or “0” of the output, and in PCM600 a lit or dimmed diode. The
second signal is the status Normal or Forced. Forced status is only
achieved when the BO is set to “Forced” or operated on the LHMI.

Set the parameter TestMode to “Off” after completing

these tests. The Start LED stops flashing when the relay
is no longer in test mode.

An initially high contact resistance does not cause problems as it is reduced quickly
by the electrical cleaning effect of fritting and thermal destruction of layers,
bringing the contact resistance back to the mOhm range. As a result, practically the
full voltage is available at the load.

• Check the status of the output circuits driving the mA outputs via the LHMI.
Select Main menu/Monitoring/I/O status/mA output modules/RTD3 and
check the output status and value for the channel under inspection.
• Test and change the output manually.
1. Select Main menu/Test/IED test mode/TestMode and set the
parameter to “On”.
2. Select Main menu/Tests/Forcing/Analog output values/RTD3.
3. Select the AOn to be forced.
4. Force the actual output using and or .

Each AOn is represented by two signals. The first signal in LHMI is the actual
primary value of the output. The second signal is the status Normal or Forced.
Forced status is only achieved when the AO is set to “Forced” on the LHMI.

When forcing analog output signals the scaling defined by

analog output channel configuration is not used. Fixed scaling
factor 1000:1 is used instead. This means that forcing value
5.000 A is seen as 5 mA when measured from output.

Do not force or send values to disconnected channels. This

results in an out-of-range error.

Forcing feature can be tested only for configured output

channels. When mA current values are forced to non-
configured output channels, values are not passed to mA output
channel HW circuitry.
