1Introduction
The D1000 Arc detection relay is a stand-alone, high speed arc protection unit for electrical power
distribution systems. The D1000 supports both point and fibre sensor technologies for optical arc
detection. The D1000 has inputs for up to six sensors and the sensors can be combined depending
on the application and requirements.
In case of an arc fault, the D1000 detects and generates a tripping pulse in less than 1 millisecond.
The tripping pulse is typically used to trip the circuit breaker(s) supplying the installation. The total
arcing time is thus reduced to the mechanical opening time of the circuit breaker, which are
approximately 50 to 75 milliseconds. The trip circuit is based on a solid state switch (IGBT), which
provides fast reaction and sufficient drive capability for even the largest circuit breakers.
The D1000 can be powered from either a DC or AC source. If the D1000 is powered from AC, it
can charge a backup battery, which can drive the trip circuit by 24 V DC.
Built-in over current protection
The D1000 integrates 3-phase current measurements for detection of short circuit and over current
with a reaction time of approximately 1 millisecond. This makes it possible to reduce unintended
tripping from external light sources, e.g. lightning or welding flashes without the extra delay and
expense of an external over current relay. The over current function can also be used to trip the
breaker in case of short circuits or long-lasting overloads without arcing.
Efficient self-supervision
The D1000 provides continuous surveillance of the complete system including the connected
sensors. Any system faults, e.g. a sensor cable fault is indicated by a flashing online LED and is
logged and reported.
Real-time event logging
The built-in USB connection provides easy access to a real-time event log, which provides detailed
diagnostic information on all events, including near misses and events related to daily operation
(e.g. configuration changes, test, reset, and power cycling).
Extended coverage with the Link Input
In order to form a larger protection system the D1000 is easily expandable. With the Link Input, up
to 4 D1000 units can be connected together, giving a total of 24 sensor inputs. Alternatively, the
link feature can be used for RS485 MODBUS RTU communication (SCADA), and thereby easily
integrate into an external monitoring and control system.

2Installation
The D1000 is secured to the rear of the switch board using four 5 mm screws or alternatively DIN
rail mounting. In case DIN rail mounting is intended, mounting brackets can be purchased
separately from SELCO.
Please ensure that enough space is given around the module so that the plug-in terminals can be
removed and re-inserted. The length of the cables should also allow for the easy removal and
insertion of the plug-in terminals.

3Power Supply
The D1000 Arc Detecting Relay can be supplied by AC or DC.
3.1 AC Supply 100 V to 230 V
Terminals 31 and 32 are used for the AC supply. The supply voltage must be between 85 to 265 V
(rated voltages from 100 V-15% to 230 V+15%).
3.2 DC Supply 100 V to 250 V
Alternatively terminals 31 and 32 can be used for the DC supply. The supply voltage must be
between 85 to 300 V (rated voltages from 100 V-15% to 250 V+20%).

SELCO A/S D1000 Manual
Revision: 29-07-2011 Page 7
3.3 DC Supply 12 V to 48 V
Terminals 34 and 36 can be used for the DC supply. The supply voltage must be between 8 V to 60
V (rated voltages from 12 V-30%to 48 V+25%).
3.4 Battery Supply 24 V
Terminals 35 and 36 can be used for DC supply by battery. The battery (Gel Cell) voltage is 24 V
DC.
Note: The D1000 includes a battery charger that will maintain the battery fully charged as
long as there is voltage on the power supply terminals 31 and 32 (regardless if this is AC or
DC). The power supply on terminals 34 and 36 cannot charge the battery.
In case the D1000 is charged by battery only and the battery voltage drops below 20 V, the D1000
will shut down in order to protect the battery. Arc monitoring is then suspended.

Revision: 29-07-2011 Page 8
4Link
The D1000 Link function supports up to 4 D1000 modules that together form one system.
The Link function enables D1000 to share sensors inputs and relay outputs as if they were one unit.
In case of an arc trip, all trip outputs of all connected D1000 modules will trip.
For the Link function to work it is necessary to configure this in the configuration tool.
4.1 Link interface
D1000 link function is programmed by selecting Link interface in the drop down menu.
4.2 Link configuration
Each D1000 must have a unique link address. The lowest address must always be 1.
The D1000 link function continuously monitors cable break faults and therefore it is required to
program the number of D1000 that are connected to the link lines.
Link terminal connections.
-Terminal 37 Link A
-Terminal 38 Link B
4.3 Button function
When the D1000 is
configured for link the front
buttons are considered linked.
Therefore if one D1000 is set
in service mode all the linked
modules are in service mode.
This also applies to the reset
button.
The Trip button will only
work locally, meaning that if
the trip button is activated in
service mode the selected
D1000 will be the only unit
that trips.

5Sensor Inputs
6 sensor inputs for light sensitive sensors are available. Four different sensor types at supported:
A1000 Photoelectric point sensors with cable monitoring
A2000 fibre optic sensors with cable monitoring
A0200 / A0300 Photoelectric point sensors without cable monitoring
Connection of the various types of sensors is explained in paragraph 4.1.1 for SENSOR 1 input
(terminals 1 –4). All other sensor inputs can be connected in the same way.

5.1 Photoelectric point sensors with cable monitoring
This sensor has a sensitive area of 180°.
The sensor signal is a mA current
signal. The sensor is factory calibrated
to 0.5 mA / klux.
The cable monitoring works via a built
in LED that is fired once every second.
In case the sensor does not detect the
light of the circuit check LED, the
sensor fail alarm is triggered.

5.1.2 Installation of point sensors in the switchboard
The point sensors are delivered with an adhesive drill guide for easy installation in the switchboard.
5.2 A2000 fibre sensor with cable monitoring
The A2000 fiber sensor is installed in the same sensor terminals as the A1000 point sensor.
However, there are more steps to connecting the A2000 due to the sensor being in three connected
parts:
1. The fiber, with an end covered in black sleeve, and an uncovered end.
2. The receiver, white cabinet with a black finger screw and an adjustment screw in the cabinet
3. The transmitter, white cabinet with a white finger screw
Both the receiver and the transmitter are connected to the D1000 using standard flexible cable.

SELCO A/S D1000 Manual
Revision: 29-07-2011 Page 12
5.2.1 Fibre
The fiber is the light collecting element of the A2000. A2000 must be mounted with a direct line-
of-sight to all current carrying parts. This can be achieved by following the bus bars along the back
wall of the cabinets.
Connect the black sleeve-covered end to the receiver (with the black finger screw) Connect the
white uncovered end to the transmitter (with the white finger screw)
The fiber should not be sharply bent or pinched. The minimum bending radius is 5 cm.
The transmitter and receiver are mounted at the ends of the fiber, fastened to the walls using rivets
or screws. The holes are prepared using the included drill guide, and the cables connected back to
the D1000. The wires of the transmitter and receiver must be connected as follows (here shown for
sensor port 1 on the D1000):

SELCO A/S D1000 Manual
Revision: 29-07-2011 Page 13
5.2.2 Receiver
Connect the red wire to pin 1
Connect the yellow wire to pin 3
Connect the white wire AND shield to pin 4
5.2.3 Transmitter
Connect the red wire to pin 1
Connect the white wire to pin 2
Connect the shield to pin 4
If installed correctly a total of three
wires connect to terminal 4, one to
terminal 3, one to terminal 2 and two to
terminal 1.
The cables can be shortened or extended up to 50 meters, but the transmitter and receiver must be
independently shielded. Failure to do so can lead to false positives for the circuit check, e.g. that a
faulty sensor is falsely detected as being present. This has no implications for the function –the
sensor will still be able to detect arc faults.
After connecting the sensor, it must be adjusted according to the length of fiber in the individual
cabinet compartments. The factory default is 60 cm/segment.

Revision: 29-07-2011 Page 14
Note: The fibre sensor comes connected to receiver, transmitter and D1000 plug in terminal.
However, it may be necessary to disconnect it from the plug in terminal during
installation.

Terminal 2 Circuit Check (transmitter) White
Terminal 3 Signal (receiver) Yellow
Terminal 4 Both shields, Circuit Check (receiver) Black/ Copper
5.2.4 Sensor adjustment according to fiber length
When delivered, the receiver is adjusted to give the same response at 60 cm of fiber installed per
compartment as an A1000 point sensor. When using the fiber optical sensor in compartments where
for example only 20 cm of the fiber is used, it is necessary to adjust the sensor sensibility. The
sensor is unable to tell the difference between 10000 lux hitting 60 cm of fiber, or 30000 lux hitting
20 cm of fiber, as the same amount of light is transported through the fiber to the receiver. Thus, to
achieve the wanted sensitivity, the receiver (with the black finger screw) must be adjusted away
from the default setting in smaller or larger compartments.
This is done by using a powerful light source, e.g. an incandescent lamp of approximately 500W,
and the following procedure:
1. Switch the D1000 to service mode by pressing the Mode button
2. Adjust the trip level setting to the lowest level (1) via the trip level dial on the D1000.
3. Slowly move the lamp towards the test sensor of the D1000
4. Note the distance from the lamp to the sensor, when the test LED lights up (approximately 50 cm).
5. Adjust the sensitivity level on the fiber receiver (black screw) to the lowest level. This is done by
turning the small metal screw approximately 10 revolutions clockwise to its maximum level.
Maximum level is when a little click sounds.
6. Place the lamp at the noted distance to the fiber sensor in the compartment closest to the
transmitter (white finger screw), as this end of the fiber has lower sensitivity.
7. Turn the metal screw on the receiver counter-clockwise until the sensor indicator LED for the fiber
lights up in red.
8. Adjust the trip level setting back to the desired position.
Now the sensitivity level of the fiber optical sensor is correctly adjusted.
5.2.5 Sensor adjustment in small compartments
If the fiber optical sensor is used in multiple compartments of varying width, the sensor must be
adjusted in the compartment of the narrowest width. If the width of the narrowest compartment
makes it difficult to follow the above procedure, e.g. the lamp cannot be placed far enough away in
the compartment, the sensitivity adjustment procedure above can be adjusted in the following way:
1. Switch the D1000 to service mode by pressing the Mode button
2. In the compartment of the narrowest width –measure the distance from the fiber optical sensor to
the lamp, when the lamp is placed at the point in the compartment where it is furthest away.

SELCO A/S D1000 Manual
Revision: 29-07-2011 Page 15
3. Set the trip level at maximum (9) on the D1000.
4. Place the lamp facing towards the test LED of the D1000, at the same distance as measured in point
2 (above).
5. Turn the trip level dial on the D1000 counter clockwise towards minimum (1) until the test LED
lights up.
6. Continue from point 5 in the procedure above.
5.3 A0200 and A0300 point sensors without cable monitoring
A0200 and A0300 were originally designed for the D0100 and D0900 Arc Detection Relays, but
can be used with the D1000 as well.
Cable monitoring is not available with these sensors.
They can be connected as follows:

Terminal 2 Not Used Not Used
Terminal 3 Signal Red
Terminal 4 Reference Green

6Placement of sensors
6.1 Switchboard Protection
The sensors used for arc detection are light sensitive sensors. Free visibility from the point where an
arc could appear to the place where the sensor is mounted is crucial.
Often it is sufficient to place one point sensor for monitoring of a complete switchboard
compartment. If there are large components that cast shadows over wider areas (e.g. circuit
breakers, more than one sensor would be required.

6.2 Transformer Protection
The Arc detection system is also used for protection of transformers. For the placement of the
sensors the same considerations apply as for the switchboard protection.
Below pictures show an example of placement of the sensors in a transformer application.

SELCO A/S D1000 Manual
Revision: 29-07-2011 Page 18
7Current Sensor
The D1000 can be combined with an over current detection. When this function is used the D1000
will only trip when both conditions are fulfilled
-light detection from the arc
-over current detection
The purpose of this function is to avoid false trips (e.g. when sunlight falls on the detector in case
the switchboard door is opened).
It is possible to configure separate over current and short circuit trips that will trip on current
detection alone.
The current sensor input uses a 5 A current transformers and the resolution is 100 mA. The
accuracy is approximately ±1 A on the secondary side of the current transformer.
The low accuracy is because D1000 is designed for speed, and for that reason it is using the
momentary values of the current instead of the RMS value. This has the very important implication
that it can also react momentarily. The function of the unit is to look for the numerically largest of
the three phases at any given sample, and compare it to the limits set up in software.
The current sensor inputs are sampled at 2 kHz and will withstand 100 A for 1 s. The burden on the
CT is less than 0.25 VA. The current sensor inputs are galvanic isolated from the rest of the unit up
to 500 V AC. The D1000 is only looking at peak currents, and is insensitive to phasing and polarity.
The current detection is not active by default, but must be set up using the USB configuration tool.

27-28 Current sensor phase 2
29-30 Current sensor phase 3

Revision: 29-07-2011 Page 19
8Auxiliary Inputs
All auxiliary inputs can be used with cable monitoring.
The cable monitoring function is enabled in the USB
configuration. If cable monitoring is enabled a resistor
of 82 kΩ must be connected in parallel with the
contact. This resistor must be connected as close as
possible to the contact.
The auxiliary inputs are all equipped with two
terminals, which are internally connected.
8.1 Inhibit
The inhibit input will suppress the trip signal.
When activated (connected to COM, terminal 45), the D1000 will only indicate that an arc fault is
detected, but will not trip the breaker.
Inhibit also block the remote trip command (terminals (41, 42)).
If D1000 detects an arc fault, the sensor LED will become active. In
INHIBIT mode, the INHIBIT LED will activate and the ONLINE relay and
ONLINE LED will deactivate in order to show that monitoring is not active.
There are two terminals for activating INHIBIT mode (terminals 39 and
40).
8.2 Trip
The trip input is used as a remote trip input. Once activated (connected to
COM, terminal 45), the D1000 trips the circuit breaker instantaneously.
There are two terminals for activating remote trip, terminals 41 and 42.
In SERVICE MODE this input is disabled.
8.3 Reset
The reset input is used as a remote reset after an arc fault. Reset is activated when connected to
COM (terminal 45).
There are two terminals for remote reset, terminals 43 and 44.
Activating the reset input will reset the tripped output and the trip coil.

9Outputs
9.1 Online
The online output is normally energized. It consists of two contact sets:
-a voltage free change over contact.
-a normally open contact with reference to COM
(terminal 45).
The online output will remain activated during monitoring.
The output will be deactivated in case the D1000:
-detects an arc
-detects a sensor fault
-loses power supply
-is switched to service Mode
-inhibit is activated
The online output is shown in de-energized position in the
drawing on the right.
9.2 Service
The service output is normally de-energized. It consists of two contact sets:
-a voltage free change over contact.
-a normally open contact with reference to COM (terminal 45).
The Service output signals that the D1000 is in service mode.
The output will activate in case the D1000:
-is switched to service Mode
-is connected via a USB cable to a PC
9.3 Tripped
The trip output is normally de-energized. It consists of two contact sets:
-a voltage free change over contact.
-a normally open contact with reference to COM (terminal 45).
The tripped output is used for signalling a trip condition to a remote monitoring system. It is not
used for the circuit breaker trip.
The tripped output will activate if the D1000 detects an arc. The tripped output is also active when
in service mode.
