Overview
VAMP 321 I/O units are listed below. Refer to the
following sections for additional information about
each I/O unit.

VAMP 321 input/output (I/O) units are classified as either light sensor or current
I/O units. The I/O units are used to connect sensors to the central unit in the
VAMP 321 arc-fault detection system. Dedicated I/O units, VAM 4C and VAM
4CD, are used to measure currents from alternative locations.
The I/O units provide active indication when appropriately placed inside the
medium voltage enclosure. They are connected to each other using intra-unit
cabling with factory-made modular cable VX001 supplied by Schnieder Electric.
NOTE: During normal operation, all necessary information about the VAMP
321 system can be read from the central unit display. However, after a new
installation or a system expansion, specific functions (zones and addresses,
trip output, etc.) will need to be programmed into the I/O unit.
For example, if an additional point sensor is added to a VAM 10L I/O unit, the
Install configuration process must be repeated before the sensor addition will
be recognized.

VAMP 321 Arc Sensors
ENGLISH
Arc sensors are connected to I/O units. They detect and transfer light
information to the I/O units. Then, the I/O units transfer information to the
central unit in the VAMP 321 arc-fault detection system.
VAMP 321 arc sensors are point and / or fiber loop sensors. Normal arc sensor
installation involves the placement of sensors in each medium voltage
enclosure.
VA 1 DA Point Arc Sensor
Figure 25: VA 1 DA Point Arc Sensors
The VA 1 DA point arc sensor is:
•
provided in standard cable lengths of 19.69 ft (6 m) and 65.62 ft (20 m).
•
surface-mountable.
•
self-supervised.
Functionality
1.
Light is detected and transferred into an electrical signal in the VA 1 DA
point arc sensor.
2.
The sensor transfers the light information to the VAM 12L, 12LD, 10L or
10LD I/O unit.
3.
The I/O unit transfers the electrical signal to the central unit.

Grounding Instructions
ENGLISH
The VAMP 321 central unit and I/O units must be grounded to the medium
voltage enclosure. Grounding through the modular cable VX001 is not
sufficient.
VAMP 321
The central unit, VAMP 321, has a dedicated ground screw on the back panel
of the unit.
Ground these units to the enclosure using a #12 or #14 ground wire.
NOTE: The ground wire length should not exceed 1.64 ft (0.5 m).
Door-mounted I/O Units
The door-mounted I/O units each have a dedicated ground screw on the back
of each unit.
Ground the door-mounted I/O units to the enclosure using a #12 or #14 gauge
ground wire.
NOTE: The ground wire length should not exceed 1.64 ft (0.5 m).
DIN Rail-mounted I/O Units
The DIN rail-mounted I/O units are to be grounded only through the DIN rail.
1.
Ground the unit upon mounting to the equipment’s DIN rail.
2.
Verify the DIN rail connection to ground with the appropriate equipment.
NOTE: The DIN rail connection between units and enclosure also must be
isolated when using modular cable VX001 so that a current is not created
because of a ground potential differential.

NOTE: If an arc fault is detected, the output closes within 7 ms when
three-phase current monitoring is used.
The central unit also has a general change over contact for arc fault trip circuits
and a separate change over contact for self-supervision alarms. Refer to
Generating Alarm Circuits on page 62 for additional information.
Tripping groups are controlled using the trip relay matrix. Refer to Figure 52
for additional information.
If several trip signals are required, the multiplying relay VARM 4R can be used.
Generating Alarm Circuits
Alarm circuits (self-supervision and trip alarms) generated by the arc-fault
detection system can be forwarded to higher-level enclosure supervision and
control systems through the output contacts.
Connecting the Self-supervision Alarms
The VAMP 321 arc-fault detection system monitors the micro controller and
related circuit operation, and program execution with a separate supervision
circuit.
Whenever the supervision circuit detects a permanent inoperative stage in
any system component, it ignores activation signals coming from that
component (for example, from a detected inoperative arc sensor).
The supervision circuit also monitors the internal operating voltage. For
instance, if operating voltage in the central unit is lost, the system automatically
gives an SF alarm since the SF output relay operates on steady-state current.
In other words, the SF relay is actuated when the operating voltage is on and
within the permitted limits.
The self-supervision system also issues a self-supervision alarm when it
detects an incorrect number of sensors. It is advised to connect the SF output
to an appropriate annunciating unit in the substation.
Connect the self-supervision alarm output to an SF change-over contact using
the following pins.
Pin No.

SF(NC) Self-supervision relay (Closed when relay is energized)
1/A/2:10, 1/A/2:12
SF(NO) Self-supervision relay (Open when relay is energized)
During normal system operation (no internal inoperative stage) and with the
auxiliary power supply connected, pin 1/A/2:10 or 1/A/2:11 is closed, and pin
1/A/2:10 or 1/A/2:12 is open.

result in death or serious injury.
Connect the secondary circuits of the current transformers to the following
screw connectors:
•
X1-1, X1-3 (L1)
•
X1-5, X1-7 (L2/I0)
•
X1-9, X1-11 (L3)
The arc detection system can also be single or two-phase connected.
Three-phase connection is nevertheless recommended for optimal operating
speed.
The current measuring channels L1 and L3 must be used in connection with
two-phase current measuring. Single-phase current or ground fault current
must always be connected to the current measuring channel L2/I0; otherwise,
an unbalance error will occur.
The specified operating time introduced in the Technical data on page 176 can
only be guaranteed for three-phase current measurement and with the proper
voltage supply to all system components, minimum allowed auxiliary voltage
measured at I/O unit's terminals is 21.6 Vdc.
The VAM 4C overcurrent unbalance alarm settings recognizes if the two-phase
or three-phase monitoring is being used based on the connections made to
the unit and the overcurrent limits set for each connection. The two-phase
connection monitoring is triggered when the L2/I0 connection overcurrent limit
differs from the L1/L3 overcurrent limit settings by 90% or more. This is because
in the event two-phase monitoring is used, the L2/I0 connection is the
connection used to monitor the ground current.
Therefore, the current limit set for the L2/I0 connection should reflect limits
associated with anticipated ground currents. The remaining L1/L3 currents
should be balanced, and overcurrent settings for the L1/L3 connection should
be reflected as such. The two-phase monitoring mode is also referred to as
“ground-fault mode.”
The three-phase monitoring is triggered when the L2/I0 and L1/L3 overcurrent
limit settings are similar, reflecting that each phase is understood to be in
balance with the other two phases.
If detected, the system gives an unbalance alarm after a 10-second delay
time. The alarm does not affect other operations of the arc detection system.
The phase discontinuity settings are non-adjustable since all the setting values
have been programmed in the current-monitoring unit.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
Connecting the trip circuits of the circuit breakers
ENGLISH
Connect the circuit breaker’s trip circuit to the following pins:
TRIP1: X2-15, X2-16
For example, in the event of an arc fault, the output contact will close at
specified time when three-phase current measurement is used.
The output trip relay of the light I/O units (VAM 10L and VAM 3 L) operates
during faults in its own zone. In the current I/O unit (VAM 4 C), select the
detection zone controlling the I/O unit using the programming switches.
If several trips are required, the multiplying relay VAMP 4R can be used. If
VAMP 4R is used, make sure that proper voltage supply is connected to
device.
Connecting between the central unit and the I/O unit
HAZARD OF EQUIPMENT DAMAGE
Connect the central unit to the I/O units with a modular cable of type VX001.
The modular cable carries all information between the central unit and I/O
units, including data in serial form, arc fault messages and operating supply
to the I/O units.
Do not connect modular cables closed loop.
•
Connect the VX001 cable to the arc I/O COM interface of the central
units.
Failure to follow these instructions can
result in personal injury or equipment
damage.
•
Connect the cable to COM1 or COM2 on the first I/O unit.
•
Route the cable from COM1 or COM2 on the first I/O unit to COM1 or
COM2 in the next unit, etc.
CAUTION
All the COM1 and COM2 interfaces are identical, i.e. the cable can always be
connected to either interface. The maximum total length of the modular cable,
taking into account all the I/O units connected to the central unit, is 328.10 ft
(100 m).
NOTE: Use only star connection for I/O units. Maximum single bus cable
length is 98 ft (30 m).

Connecting separate auxiliary supplies
ENGLISH
When routing modular cables over long distances (98.43 ft of modular cabling)
or when the system contains more than 4 I/O units you should preferably use
a separate auxiliary +24Vdc voltage supply with output monitoring along with
the modular bus cabling.
Recommended types of power supplies with output monitoring:
1.
Phaseo ABL4RSM24035 (3.5A @ 24Vdc)
2.
Phaseo ABL4RSM24050 (5A @ 24Vdc)
3.
or any equivalent type of power supply with above functionality
NOTE: Use of power supplies without voltage monitoring is not recommended.
Connect the auxiliary supply to the 24 V terminals of the last I/O unit. Use at
least 1.5mm2 (AWG 16) size twisted pair cable.
NOTE: It is recommended to use external wiring to connect auxiliary supply
to all units. Pay particular attention to the polarity of the wire and cable
connections.
Additional power supply cabling is recommended, min. AWG 16 (1.5
mm2)
Power supply cabling, min. AWG 16 (1.5 mm2)

VA 1 DA Point Arc Sensors
ENGLISH
Installing the VA 1 DA
The VAMP 321 arc sensors should be mounted on the enclosure so that they
cover the detection zone as completely as possible.
If arc point sensors are used in open compartments, such as busbar sections,
sensors should be placed at a minimum every 9.85 ft (3 m) in the
compartments. The mounting position is not critical because of the wide sensor
detection range and the light reflection inside the enclosure.
Figure 43: VA 1 DA Point Arc Sensor Sensitivity
Refer to Figure 44.
To install the VA 1 DA point arc sensors onto the outside enclosure wall:
Push the active part of the sensor through the 0.39 in. (10 mm) hole in the
wall. Secure it using a #8 (4 mm) screw.
To surface-mount the VA 1 DA point sensors to the wall:
Install mounting plates VYX002 or VYX001. Order brackets separately (not
included with the arc sensor). Refer to Figure 45 and Figure 46.

NOTE: The sensors must not be exposed to direct sunlight or other light. Do
not mount the sensors directly under a light source. If the sensor is exposed
to a light exceeding pick-up criteria (8000 lx) for over 3 seconds the sensor
channel is blocked. It will become operational again once the light source is
removed.
Before final commissioning:
•
Verify that the surrounding light sources near the point arc sensors do
not activate the sensors’ channel.
•
Consider light exposure with and without doors closed and possible
maintenance or inspection. The rear of the point arc sensors can also
detect sources of light.
Connecting the VA 1 DA Point Arc Sensors to the I/O Units
The sensors are equipped with the standard 19.69 ft (6m) cable or a 64.36 ft
(20m) shielded cable (to be specified in the order).
After mounting the sensors, connect them to the I/O units as follows:
© 2014 Schneider Electric All rights reserved
1.
Determine suitable cable length using the shortest route possible to the
nearest I/O unit.
2.
Cut the wire at the length determined in step 1.
3.
Connect the arc sensors to the screw pins X1:1 – X1:20. The arc sensors’
cable polarity is not critical.
4.
Cables should be in LV compartment (only required part the primary
area) as far from from the primary bus bars and cables as possible.

VAMP 4R Multiplying Relay
ENGLISH
Installing the VAMP 4R
The multiplying relay VAMP 4R can be used when additional trip outputs are
needed.
VAMP 4R is comprised of four (4) Normally Open (NO) contacts and four (4)
Normally Closed (NC) contacts. They are divided into two separate groups
that can be controlled independently for example, by the binary output of the
I/O units or the VAMP 221 central unit.
Attach the VAMP 4R unit to a DIN rail. Refer to the numbered steps and
measurements shown in Figure 47 to install the VAMP 4R multiplying relay.
NOTE: Tighten all terminal block screws during installation of a multiplying
relay.

ENGLISH
Arc flash detection
Signals in arc matrix - light and arc matrix - current menu are intended to be
connected to Arc Stages 1 – 8. Further in arc matrix - output menu Arc Stages
are defined to control the output signals, such as output relays.
Arc stages can be imagined as "logical AND gate" which input signals are arc
matrix - light and arc matrix - current. Output signal of this "AND gate" is arc
matrix - output.
Arc flash detection menus
The arc flash detection menus are located in the main menu under ARC. The
ARC menu can be viewed either on the local HMI, or by using VAMPSET.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
Event log
Event log is a buffer of event codes and time stamps including date and time.
For example each start-on, start-off, trip-on or trip-off of any detection stage
has a unique event number code. Such a code and the corresponding time
stamp is called an event.
As an example of information included with a typical event a programmable
stage trip event is shown in the following table.

Events are the major data for a SCADA system. SCADA systems are reading
events using any of the available communication protocols. Event log can also
be scanned using the front panel or using VAMPSET. With VAMPSET the
events can be stored to a file especially in case the relay is not connected to
any SCADA system.
Only the latest event can be read when using communication protocols or
VAMPSET. Every reading increments the internal read pointer to the event
buffer. (In case of communication interruptions, the latest event can be reread
any number of times using another parameter.) On the local panel scanning
the event buffer back and forth is possible.
Event enabling/masking
In case of an uninteresting event, it can be masked, which prevents the
particular event(s) to be written in the event buffer. As a default there is room
for 200 latest events in the buffer. Event buffer size can be modified from 50
to 2000.
Modification can be done in “Local panel conf” –menu.
Indication screen (popup screen) can also be enabled in this same menu when
VAMPSET –setting tool is used. The oldest one will be overwritten, when a
new event does occur. The shown resolution of a time stamp is one millisecond,
but the actual resolution depends of the particular function creating the event.
For example most detection stages create events with 5ms, 10 ms or 20 ms
resolution. The absolute accuracy of all time stamps depends on the time
synchronizing of the relay. See System clock and synchronization on page 90
for system clock synchronizing.
Event buffer overflow
The normal procedure is to poll events from the device all the time. If this is
not done then the event buffer could reach its limits. In such case the oldest
event is deleted and the newest displayed with OVF code in HMI.

Disturbance recorder
The disturbance recorder can be used to record all the measured signals, that
is, currents, voltage and the status information of digital inputs (DI) and digital
outputs (DO).
The digital inputs also include the arc detection signals.
Triggering the recorder
The recorder can be triggered by any start or trip signal from any detection
stage or by a digital input. The triggering signal is selected in the output matrix
(vertical signal DR). The recording can also be triggered manually. All
recordings are time stamped.
Reading recordings
The recordings can be uploaded, viewed and analysed with the VAMPSET
program. The recording is in COMTRADE format. This also means that other
programs can be used to view and analyse the recordings made by the relay.
For more details, please see a separate VAMPSET manual.
Number of channels
86
At the maximum, there can be 12 recordings, and the maximum selection of
channels in one recording 12 (limited in wave form) and digital inputs reserve
one channel (includes all the inputs). Also the digital outputs reserve one
channel (includes all the outputs). If digital inputs and outputs are recorded,
there will be still 10 channels left for analogue waveforms.

Section 4— Installation, Wiring and Functionality
Virtual comtrade files can be run with the device. Device behaviour can be
analysed by playing the recorder data over and over again in the relay memory.
NOTE: This is not applicable to the arc detection functions of the device.
Steps of opening the VAMPSET setting tool:
1.
Go to “Disturbance record” and select Open… (A).
2.
Select the comtrade file from you hard disc or equivalent. VAMPSET is
now ready to read the recording.
3.
The virtual measurement has to be enabled (B) in order to send record
data to the relay (C).
4.
Sending the file to the device’s memory takes a few seconds. Initiate
playback of the file by pressing the Go! button (D). The “Change to control
mode” button takes you back to the virtual measurement.
NOTE: The sample rate of the comtrade file has to be 32/cycle (625 micro
seconds when 50 Hz is used). The channel names have to correspond to the
channel names in VAMP relays: IL1, IL2, IL3, I01, I02, U12, U23, UL1, UL2, UL3
and U0.

System clock and synchronization
ENGLISH
The internal clock of the relay is used to time stamp events and disturbance
recordings.
The system clock should be externally synchronised to get comparable event
time stamps for all the relays in the system.
The synchronizing is based on the difference of the internal time and the
synchronising message or pulse. This deviation is filtered and the internal time
is corrected softly towards a zero deviation.
Time zone offsets
Time zone offset (or bias) can be provided to adjust the local time for IED.
The Offset can be set as a Positive (+) or Negative (-) value within a range of
-15.00 to +15.00 hours and a resolution of 0.01/h. Basically quarter hour
resolution is enough.
Daylight saving time (DST)
-
IED provides automatic daylight saving adjustments when configured. A
daylight savings time (summer time) adjustment can be configured separately
and in addition to a time zone offset.
Daylight time standards vary widely throughout the world. Traditional daylight/summer time is configured as one (1) hour positive bias. The new
US/Canada DST standard, adopted in the spring of 2007 is: one (1) hour
positive bias, starting at 2:00am on the second Sunday in March, and ending
at 2:00am on the first Sunday in November. In the European Union, daylight
change times are defined relative to the UTC time of day instead of local
time of day (as in U.S.) European customers, please carefully find out local
country rules for DST.
The daylight saving rules for Finland are the IED defaults (24-hour clock):
- Daylight saving time start: Last Sunday of March at 03.00
- Daylight saving time end: Last Sunday of October at 04.00
To ensure proper hands-free year-around operation, automatic daylight time
adjustments must be configured using the “Enable DST” and not with the
time zone offset option.

Section 4— Installation, Wiring and Functionality
Adapting auto adjust
During tens of hours of synchronizing the device will learn its average deviation
and starts to make small corrections by itself. The target is that when the next
synchronizing message is received, the deviation is already near zero.
Parameters "AAIntv" and "AvDrft" will show the adapted correction time interval
of this ±1 ms auto-adjust function.
Time drift correction without external sync
If any external synchronizing source is not available and the system clock has
a known steady drift, it is possible to roughly correct the clock deviation by
editing the parameters "AAIntv" and "AvDrft". The following equation can be
used if the previous "AAIntv" value has been zero.
AAIntv =
604.8
DriftInOneWeek
If the auto-adjust interval "AAIntv" has not been zero, but further trimming is
still needed, the following equation can be used to calculate a new auto-adjust
interval.
AAIntvNEW =
1
AAIntvPREVIOUS
1
DriftInOneWeek
+
604.8
The term DriftInOneWeek/604.8 may be replaced with the relative drift
multiplied by 1000, if some other period than one week has been used. For
example if the drift has been 37 seconds in 14 days, the relative drift is
37*1000/(14*24*3600) = 0.0306 ms/s.
Example 1
If there has been no external sync and the relay's clock is leading sixty-one
seconds a week and the parameter AAIntv has been zero, the parameters
are set as
AvDrft = Lead
AAIntv =
604.8
= 9. 9 s
61
With these parameter values the system clock corrects itself with –1 ms every
9.9 seconds which equals –61.091 s/week.
Example 2
If there is no external sync and the relay's clock has been lagging five seconds
in nine days and the AAIntv has been 9.9 s, leading, then the parameters are
set as
AAIntv NEW =
1
= 10.6
1
5000
−
9.9 9 ⋅ 24 ⋅ 3600
AvDrft = Lead
If there is no external sync and the relay's clock has been lagging five seconds
in nine days and the AAIntv has been 9.9 s, leading, then the parameters are
set as
When the internal time is roughly correct – deviation is less than four seconds
– any synchronizing or auto-adjust will never turn the clock backwards. Instead,
in case the clock is leading, it is softly slowed down to maintain causality.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
Clock can be synchronized by reading minute pulses from digital inputs, virtual
inputs or virtual outputs. Sync source is selected with SyncDI setting.
When rising edge is detected from the selected input, system clock is adjusted
to the nearest minute. Length of digital input pulse should be at least 50 ms.
Delay of the selected digital input should be set to zero.
Synchronisation correction
If the sync source has a known offset delay, it can be compensated with SyOS
setting. This is useful for compensating hardware delays or transfer delays of
communication protocols. A positive value will compensate a lagging external
sync and communication delays. A negative value will compensate any leading
offset of the external synch source.
Sync source
When the device receives new sync message, the sync source display is
updated. If no new sync messages are received within next 1.5 minutes, the
device will change to internal sync mode.
Sync source: IRIG-B003
IRIG-B003 synchronization is supported with a dedicated communication
option with either a two-pole or two pins in a D9 rear connector (See Order
information on page 187).
IRIG-B003 input clock signal voltage level is TLL. The input clock signal
originated in the GPS receiver must be taken to multiple relays trough an
IRIG-B distribution module. This module acts as a centralized unit for a
point-to-multiple point connection. Note: Daisy chain connection of IRIG-B
signal inputs in multiple relays must be avoided.

Deviation
The time deviation means how much system clock time differs from sync
source time. Time deviation is calculated after receiving new sync message.
The filtered deviation means how much the system clock was really adjusted.
Filtering takes care of small deviation in sync messages.
Auto-lag/lead
The device synchronizes to the sync source, meaning it starts automatically
leading or lagging to stay in perfect sync with the master. The learning process
takes few days.
Non-volatile RAM
The non-volatile RAM of the device is implemented using a super capacitor
and a RAM memory with low power consumption.
When auxiliary power is on the super capacitor is charged from the internal
power supply of the device and the non-volatile RAM memory also gets power
from the same source. When auxiliary power is turned off the RAM memory
is powered by the super capacitor. The memory will keep its contents as long
as there is enough voltage in the super capacitor. This time is 7 days in +77°F
room temperature – high humidity will decrease the time.
The non-volative RAM is used to store the disturbance recordings and the
event-buffer.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
The functions of the microcontroller and the associated circuitry, as well as
the program execution are supervised by means of a separate watchdog
circuit. Besides supervising the relay, the watchdog circuit attempts to restart
the micro controller in an inoperable situation. If the micro controller does not
resart, the watchdog issues a self-supervision signal indicating a permanent
internal condition.
When the watchdog circuit detects a permanent fault, it always blocks any
control of other output relays (except for the self-supervision output relay and
the output relays used in the arc detection function).
The condition of the VAMP 321 central unit, the I/O units and the sensors are
supervised. Events are generated when possible problems occur or disappear.
The events are stored in the IED event buffer and they can be read on the
local HMI or VAMPSET. Channel, events codes and situations where events
are generated:
134E1 - 134E10:
Arc sensor 1 - 10 not conn. improper connection ON
134E11 - 134E20:

135E4:
I/O unit ArcI/O bus C interruption OFF (I/O unit number also shown)
135E9:
I/O unit ArcI/O bus R interruption ON (I/O unit number also shown)
135E10:
I/O unit ArcI/O bus R interruption OFF (I/O unit number also shown)
Communication interruption between the VAMP 321 and I/O units is also
shown by “Arc I/O bus signal” in the output matrix and logics.
Only some of the communication protocols (IEC 61850, SPA-bus, Modbus
and ModbusTCP) have capability to transfer all of these events. In some
protocols only a selected subset can be left off or only status of COM5 is
available with the help of logic programming.
Diagnostics
The device runs self-diagnostic tests for hardware and software in boot
sequence and also performs runtime checking.
Permanent inoperative state
If permanent inoperative state has been detected, the device releases SF
relay contact and status LED is set on. Local panel will also display a detected
fault message. Permanet inoperative state is entered when the device is not
able to handle main functions.
Temporal inoperative state
When self-diagnostic function detects a temporal inoperative state, Selfdiag
matrix signal is set and an event (E56) is generated. In case the inoperative
state was only temporary, an off event is generated (E57). Self diagnostic
state can be reset via local HMI.
Diagnostic registers
There are four 16-bit diagnostic registers which are readable through remote
protocols. The following table shows the meaning of each diagnostic register
and their bits.

ENGLISH
Output relays
The output relays are also called digital outputs. Trip contacts can be controlled
by using relay output matrix or logic function. Also forced control is possible.
When using force controlling it has to be first enabled in the “relays” menu.
The output relays are also called digital outputs. Any internal signal can be
connected to the output relays using "OUTPUT MATRIX" and/or "ARC MATRIX
- OUTPUT". An output relay can be configured as latched or non-latched.
The position of the contact can be checked in “output matrix” and “relays”
menu. An output relay can be configured as latched or non-latched. Latched
relay contacts can be set free by pressing the “enter” key of the IED or by
releasing from VAMPSET setting tool.
The difference between trip contacts and alarm contacts is the DC breaking
capacity. The contacts are single pole single throw (SPST) normal open
type (NO), except alarm relay A1 which has change over contact single pole
double throw (SPDT).

Digital inputs are available for control purposes. The number of available inputs
depends on the number and type of option cards.
The polarity – normal open (NO) / normal closed (NC) – and a delay can be
configured according the application by using the local HMI or VAMPSET.
Digital inputs can be used in many operations. The status of the input can be
checked in relay “output matrix” and “digital inputs” menu. Digital inputs makes
possible to change group, block/enable/disable functions, to program logics,
indicate object status, etc.
The digital inputs do require an external control voltage (ac or dc). Digital input
will be activated after activation voltage exceeds. Deactivation follows when
the voltage drops below threshold limit. Activation voltage level of digital inputs
can be selected in order code when such option cards are equipped.

Binary inputs and outputs
ENGLISH
Information from the arc deection function can be transmitted and/or received
through binary inputs (BI) and outputs (BO). The rated voltage of these signals
is 30 V dc when active. The input signal has to be 18 – 250 V dc to be
activated.
Binary inputs
The binary inputs (BI) can be used to get the light indication from another IED
to build selective arc detection systems. BI is a dry input for 18 – 250 V dc
signal. The connection of BI signals is configured in the matrices of the arc
flash detection function.
Binary output
The binary outputs (BO) can be used to give the light indication signal or any
other signal or signals to another IED's binary input to build selective arc
detection systems. BO is an internally driven (wetted) 30 Vdc signal. The
connection of BO signals is configured in the matrices of the arc flash detection
function.
Virtual inputs and outputs
There are virtual inputs and virtual outputs, which can in many places be used
like their hardware equivalents except that they are only located in the memory
of the device. The virtual inputs acts like normal digital inputs. The state of
the virtual input can be changed from local display, communication bus and
from VAMPSET. For example setting groups can be changed using virtual
inputs.
Virtual inputs can be used in many operations. The status of the input can be
checked in “output matrix” and “virtual inputs” menu. Status is also visible on
local mimic display if so selected. Virtual inputs can be selected to be operated
trough function buttons F1 and F2, trough local mimic or simply by using the
virtual input menu. Virtual inputs makes possible to change group,
block/enable/disable functions, to program logics and other similar to digital
inputs.
Activation and reset delay of input is approximately 5ms. See specification

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
Output matrix
By means of the output matrix, the output signals of the various detection
stages, digital inputs, logic outputs and other internal signals can be connected
to the output relays, virtual outputs, etc.
NOTE: For configuring the high-speed operations of the arc detection the
“ARC MATRIX – OUTPUT” must be used.
There are general purpose LED indicators – "A", "B", "C" to ”N” – available
for customer-specific indications on the front panel. Their usage is define in
a separate LED MATRIX.
Furthermore there are two LED indicators specified for keys F1 and F2. In
addition, the triggering of the disturbance recorder (DR) and virtual outputs
are configurable in the output matrix.
See an example in Figure 70.
Figure 70: Output matrix
An output relay or indicator LED can be configured as latched or non-latched.
A non-latched relay follows the controlling signal. A latched relay remains
activated although the controlling signal releases.
Figure 71: Release output matrix latches
There is a common "release all latches" signal to release all the latched relays.
This release signal resets all the latched output relays and indicators with CPU
and FPGA control. The reset signal can be given via a digital input, via HMI
or through communication. The selection of the input is done with the
VAMPSET software under the menu "Release output matrix latches". See an
example in Figure 71.
"Release all latches" signal clears and resets FPGA controlled latches.

Blocking matrix
ENGLISH
By means of a blocking matrix, the operation of any detection stage (except
the arc detection stages) can be blocked. The blocking signal can originate
from the digital inputs or it can be a start or trip signal from a detection stage
or an output signal from the user's programmable logic. In the Figure 72, an
active blocking is indicated with a black dot (●) in the crossing point of a
blocking signal and the signal to be blocked.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
The device allows controlling of six objects, that is, circuit-breakers,
disconnectors and grounding switches. Controlling can be done by
"select-execute" or "direct control" principle.
The object block matrix and logic functions can be used to configure
interlocking for a safe controlling before the output pulse is issued. The objects
1 – 6 are controllable while the objects 7 – 8 are only able to show the status.
Controlling is possible by the following ways:
•
through the local HMI
•
through a remote communication
•
through a digital input
•
through the function key
The connection of an object to specific output relays is done via an output
matrix (object 1 – 6 open output, object 1 – 6 close output). There is also an
output signal “Object failed”, which is activated if the control of an object is
not completed.
Object states
Each object has the following states:
Setting
Value
Object state
Description
Undefined (00)
Actual state of the object
Open
Close
Undefined (11)
Basic settings for controllable objects
Setting
DI for ‘obj open’
Each controllable object has the following settings:
Value
Description
None, any digital input, virtual input or virtual output
Open information
DI for ‘obj close’
Close information
DI for ‘obj ready’

Max ctrl pulse length
0.02 – 600 s
Pulse length for open and close commands
Completion timeout
0.02 – 600 s
Timeout of ready indication
Object control

If changing states takes longer than the time defined by “Max ctrl pulse length”
setting, object is inoperative and “Object failure” matrix signal is set. Also
undefined-event is generated. “Completion timeout” is only used for the ready
indication. If “DI for ‘obj ready’” is not set, completion timeout has no meaning.
Output signals of controllable objects
Each controllable object has 2 control signals in matrix:
Output signal
Description
Object x Open
Open control signal for the object
Object x Close
Close control signal for the object
These signals send control pulse when an object is controlled by digital input,
remote bus, auto-reclose etc.

Local/Remote selection
In Local mode, the output relays can be controlled via a local HMI, but they
cannot be controlled via a remote serial communication interface.
In Remote mode, the output relays cannot be controlled via a local HMI, but
they can be controlled via a remote serial communication interface.
The selection of the Local/Remote mode is done by using a local HMI, or via
one selectable digital input. The digital input is normally used to change a
whole station to a local or remote mode. The selection of the L/R digital input
is done in the “Objects” menu of the VAMPSET software.
A password is not required for a remote control operation.
Controlling with DI
Objects can be controlled with digital input, virtual input or virtual output. There
are four settings for each controllable object:
Setting
Active
DI for remote open / close control
In remote state
DI for local open / close control
In local state
If the device is in local control state, the remote control inputs are ignored and
vice versa. Object is controlled when a rising edge is detected from the selected
input. Length of digital input pulse should be at least 60 ms.

The three phase current measurement and ground fault current measurement for arc detection is done with electronics (see Figure 79). The electronics compares the current levels to the pick-up settings - THRESHOLDs
- and gives a binary signal “I>>” or “I0>>” to the arc detection function if
limit is exceeded. All the frequency components of the currents are taken
into account.
Signals “I>>” or “I0>>” are connected to a FPGA chip which implements
the arc detection function. The pick-up settings are named “I> int” and “I0>
int” in the local LCD panel or VAMPSET views, these settings are used
to set the THRESHOLD levels for the electronics.
The accuracy of the arc detection measurements is as follows:
•
Under nominal current: 2.5% (1 of nominal
•
Over nominal current: 2.5% (1 of measured/injected value

The device calculates the THDs as percentage of the base frequency for
currents and voltages.
The device calculates the harmonics from the 2nd to the 15th of phase currents
and voltages. (The 17th harmonic component will also be shown partly in the
value of the 15th harmonic component. This is due to the nature of digital
sampling.)
The harmonic distortion is calculated using equation

For reference the RMS value is
RMS = 100 2 + 10 2 + 3 2 + 8 2 = 100.9 A
Another way to calculate THD is to use the RMS value as reference instead
of the fundamental frequency value. In the example above the result would
then be 13.0 %.

Primary secondary and per unit scaling
ENGLISH
Many measurement values are shown as primary values although the relay
is connected to secondary signals. Some measurement values are shown as
relative values - per unit or percent.
The scaling is done using the given CT, VT values.
The following scaling equations are useful when doing secondary testing.
Current scaling
The rated value of the device's current input, for example 5 A or 1A, does not
have any effect in the scaling equations, but it defines the measurement range
and the maximum allowed continuous current. See Table 71 for details.
Primary and secondary scaling
Current scaling
secondary → primary
I PRI = I SEC ⋅
CTPRI
CTSEC
primary → secondary
I SEC = I PRI ⋅
CTSEC
CTPRI
For residual current to input I0 use the corresponding CTPRI and CTSEC values.
For ground fault stages using I0Calc signals use the phase current CT values
for CTPRI and CTSEC.
For residual current to input I0 use the corresponding CTPRI and CTSEC values.
For ground fault stages using I0Calc signals use the phase current CT values
for CTPRI and CTSEC.
Examples:
1.
Secondary to primary
CT = 500 / 5
Current to the relay's input is 4 A.
=> Primary current is IPRI = 4 x 500 / 5 = 400 A
2.
Primary to secondary
CT = 500 / 5
The relay displays IPRI = 400 A
=> Injected current is ISEC = 400 x 5 / 500 = 4 A

COM 1-COM 4 are serial ports for communication with protocols like IEC 103.
The type of the physical interface on these ports depends on the type of the
selected communication option module. The use of some protocols may require
a certain type of option module for example ProfibusDP can only be used with
external profibus module VPA 3CG, if the hardware interface of the COM port
is RS-232.
The parameters for these ports are set via local HMI or with VAMPSET in

KeepAlive: The KeepAlive parameter sets in seconds the time between two keepalive packets that are sent from the IED. The setting range for
this parameter is between zero (0) and 20 seconds; with the exception that zero (0) means actually 120 seconds (2 minutes). A keep alive’s
packet purpose is for the VAMP IED to send a probe packet to a connected client for checking the status of the TCP-connection when no other
packet is being sent e.g. client does not poll data from the IED. If the keepalive packet is not acknowledged, the IED will close the TCP connection.
Connection must be resumed on the client side.

This is and ASCII protocol used by VAMPSET. This protocol is the protocol
used on the USB port. This can also be used on the COM ports, if VAMPSET
interface via these ports is required.
Modbus TCP and Modbus RTU
These Modbus protocols are often used in power plants and in industrial
applications. The difference between these two protocols is the media. Modbus
TCP uses Ethernet and Modbus RTU uses asynchronous communication
(RS-485, optic fiber, RS-232).
VAMPSET will show the list of all available data items for Modbus.
The Modbus communication is activated usually for remote port via a menu

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
The Profibus DP protocol is widely used in industry. An external VPA 3CG
and VX072 cables are required.
Device profile "continuous mode"
In this mode, the device is sending a configured set of data parameters
continuously to the Profibus DP master. The benefit of this mode is the speed
and easy access to the data in the Profibus master. The drawback is the
maximum buffer size of 128 bytes, which limits the number of data items
transferred to the master. Some PLCs have their own limitation for the Profibus
buffer size, which may further limit the number of transferred data items.
Device profile "Request mode"
Using the request mode it is possible to read all the available data from the
VAMP device and still use only a very short buffer for Profibus data transfer.
The drawback is the slower overall speed of the data transfer and the need
of increased data processing at the Profibus master as every data item must
be separately requested by the master.
NOTE: In request mode, it is not possible to read continuously only one single
data item. At least two different data items must be read in turn to get updated
data from the device.
There is a separate manual for VPA 3CG (VVPA3CG/EN M/xxxx) for the
continuous mode and request mode. The manual is available to download
from our website.
Available data
VAMPSET will show the list of all available data items for both modes. A
separate document “Profibus parameters.pdf” is also available.
The Profibus DP communication is activated usually for remote port via a
menu selection with parameter "Protocol". See Communication ports on
page 130.

bits, measurement values or setting values with one message is supported.
Several simultaneous instances of this protocol, using different physical ports,
are possible, but the events can be read by one single instance only.

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 4— Installation, Wiring and Functionality
The IEC standard 60870-5-103 "Companion standard for the informative
interface of protection equipment" provides standardized communication
interface to a primary system (master system).
The unbalanced transmission mode of the protocol is used, and the device
functions as a secondary station (slave) in the communication. Data is
transferred to the primary system using "data acquisition by polling"-principle.
The IEC functionality includes application functions:
•
station initialization
•
general interrogation
•
clock synchronization and
•
command transmission.
It is not possible to transfer parameter data or disturbance recordings via the
IEC 103 protocol interface.
The following ASDU (Application Service Data
Unit) types will be used in communication from the
device:
The device will accept:
The data in a message frame is identified by:
•
ASDU 1: time tagged message
•
ASDU 3: Measurands I
•
ASDU 5: Identification message
•
ASDU 6: Time synchronization and
•
ASDU 8: Termination of general interrogation.
•
ASDU 6: Time synchronization
•
ASDU 7: Initiation of general interrogation and
•
ASDU 20: General command.
•
type identification
•
function type and
•
information number.
These are fixed for data items in the compatible range of the protocol, for
example, the trip of I> function is identified by: type identification = 1, function
type = 160 and information number = 90. "Private range" function types are
used for such data items, which are not defined by the standard (e.g. the status
of the digital inputs and the control of the objects).
The function type and information number used in private range messages is
configurable. This enables flexible interfacing to different master systems.
For more information on IEC 60870-5-103 in VAMP devices refer to the
“IEC103 Interoperability List” document.

Depending on the pre-made configuration user can get alarm display showing
what has occurred during the fault. The alarm display shows event buffer row
by row. Next event view is chosen by Enter key.
The mimic of the IED can also show fault data for instance with statuses of
the circuit breakers. Also number of arc detection activations (start) and
operation (trip) be seen through mimic.
Reading fault data captured during arc fault
As described above and depending on the pre-made configuration LED display
and mimic indicate fault data. In addition to this, user can track following
information from IED’s memory as follows:
- Event log
“Event buffer” menu shows following data:
•
Sequence number of the event
•
Date and time
•
Event code and description

VAMP 321 Arc-fault Detection System for Medium Voltage Applications
Section 5— Programming and Troubleshooting
The I/O unit programming switches are used to determine the unit address
and trip relay function.
•
Set the programming switches before connecting the supply voltage.
•
If you have to change the switch positions once the supply voltage has
been connected, disconnect the supply voltage to the unit in question for
the duration of the programming and re-configure the system.
•
If position of the switch is changed, re-install the system again in the
central unit.
The system accommodates up to 16 I/O units. Eight (8) addresses are reserved
for each detection zone:
•
Zone 1 addresses 0 – 7
•
Zone 2 addresses 8 – 15
•
Zone 3 addresses 16 – 23
•
Zone 4 addresses 24 – 31
I/O Unit Address Creation and Assignment
The programming switches have different weighted coefficients.
To create an address for the I/O unit:
1.
Turn switches with different values to the ON position.
2.
Calculate the sum of their weighted coefficients.
The following table shows the weighted coefficients of each programming
switch.

VAM 12L / VAM 12LD, VAM 10L / VAM 10LD, VAM 3L and VAM 3LX only
The address range for current I/O units is (32), 33 – 46 (Zone 5).
NOTE: Do not use address 32. In this case, the current I/O unit operates in
Central Unit mode, and the actual central unit must be set to Sub-Unit mode.
To determine the address of a current I/O unit, add the sum of the weighted
coefficients to 32.
Example
Programming switch values total 7, address of the current I/O unit is 32:
(32 + 7 = 39).
NOTE: Do not use 32 as the unit address if system has a central unit. Other
programming switches have different functions in different units, as described
in the following sections.

Maintenance
ENGLISH
The VAMP 321 IED and its extension units require maintenance in order to
work according to specification. Keep record of the maintenance actions
performed for the system. The maintenance can include, but is not limited the
following actions.
Preventative maintenance
The VAMP 321 IED and its extension units, sensor and cabling shall be visually
checked when the switchgear is de-energized. During such inspection pay
attention to
•
possible dirty arc sensors
•
loose wire connections
•
damaged wiring
•
indicator lights ( see section LED test sequence) and
•
other mechanical connections.
Visual inspection shall be made maximum every three (3) years.
Periodical testing
The IED and its satellite extension units, cabling and sensors must periodically
be tested according to the end-user's safety instructions, national safety
instructions or law. Manufacturer recommend functional testing being carried
minimum every five (5) years.
It is proposed that the periodic testing is conducted with a secondary injection
principle for those detection stages which are used in the IED and its extension
units.
Follow separate testing manual (VARCTEST/EN/M_xxxx) for a test protocol.
Cleaning of hardware
Special attention must be paid that the IED, it's extension units and sensors
do not become dirty. In case cleaning is required, wipe out dirt from the units.
Sensor condition and positioning check
After commissioning, sensor replacement, modification procedure, cleaning
and periodical testing always check that the sensor positioning remains as it
was originally designed.
System status messages
In case IED's self checking detects unindented system status it will in most of
the cases provide alarm concerning this by activating the Service LED and
indication status notification on the LCD screen. Should this happen store the
possible message and contact your local representative for further guidance.
Spare parts
Use entire unit as a spare for the device to be replaced. Always store spare
parts in storage areas that meet requirements stated in Test and environmental
conditions on page 180.

Connection Example
ENGLISH
VAMP 321
Typical connection of VAMP 321 where all three phase currents and neutral
current are detected. A three phase current phase connection is required in
order maintain specified operation time. Neutral current measurement could
also be used as a current criteria for the arc flash protection scheme. Status
of the circuit breaker is monitored using digital inputs DI9 and DI10. Circuit
breaker position can be shown on the single line diagram of the mimic and be
transferred to automation through through Ethernet or serial communication
protocols. Circuit breaker open and close commands are made with T1 and
d T2 outputs respectively. Self diagnostic alarm, SF is recommended to be
connected in the general alarm unit, if available, of the substation.

VAM 12L and VAM 12LD I/O Unit Diagram
ENGLISH
The VAM 12L I/O unit is primarily designed for selective feeder trip (cable
compartment) applications in the case of an arc fault. Each VAM 12L and
VAM 12LD I/O unit is comprised of three (3) electromechanical trip Normally
Open (NO) contacts and one (1) trip alarm change-over contact.
Refer to Figure 114. In this example, by setting L>int/ext to ext mode, all three
(3) trip outputs will trip for a fault in zone, which will also isolate outgoing
feeders for a fault in the busbar compartment.

Functional description
ENGLISH
In this application example, the arc flash sensor for zone 1.1 is connected to
the I/O unit input number 1. If the arc flash sensor awakens and simultaneously
VAMP 321 sends a current signal to the I/O unit, the zone 1.1 is isolated by
the outgoing feeder breaker.
The arc flash sensor for zone 1.2 is connected to the I/O unit input number 2
or 3. If the arc flash sensor awakens and simultaneously VAMP 321 sends a
current signal to the I/O unit, the zone 1.2 is isolated by the outgoing feeder
breaker.
The arc flash sensors for zone 1 are connected to the I/O unit sensor channels
4 – 10. If a sensor awakens in zone 1, the light-only signal is transferred to
VAMP 321 which then trips the main circuit breaker.
NOTE: For 12L and 12LD units, three sensor channels can trip their own zone
independently, the other seven sensor channels can be allocated to another
zone.
The sensor S2 connected to VAMP 321 in zone B overlaps zone A. If the
circuit breaker fails to isolate the failure in zone B, the sensor (S2) generates
a time-delayed circuit-breaker failure protection trip to the upstream breaker.
The incoming feeder circuit breaker has a CBFP backup trip to the upstream
breaker. If zone 1 trip (T1) fails, the CBFP takes over and trips the upstream
circuit breaker.
Zone A illustrates a typical medium voltage incoming feeder where the current
transformers are located after the cable termination. In this case, an eventual
arc flash fault in the cable termination does not activate the current element
in VAMP 321. However, arc detection can be achieved by using the light-only
principle. If an arc flash occurs in cable termination, zone A is tripped by an
upstream circuit breaker. The sensor S1 in zone A overlaps the incoming
circuit breaker.
Zone A operates on light-only principle as the currents are not available for
current and light operation.
The circuit-breaker failure protection (CBFP) protects in case there is a
detected failure in zone 1, or in sensor S2 in zone B. The trip output (T2/CBFP)
can function as a trip output, but also as a time-delayed circuit-breaker failure
protection. To enable CBFP, an additional time-delayed stage needs to be
created.
