    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.

  • Page 5: Installation

    D1000 Manual 2 Installation 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.

    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.

  • Page 8: Link

    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.

  • Page 9: Sensor Inputs

    SELCO A/S D1000 Manual 5 Sensor 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...

  • Page 16: Placement Of Sensors

    SELCO A/S D1000 Manual 6 Placement 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.

  • Page 17: Transformer Protection

    SELCO A/S D1000 Manual 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.

  • Page 18: Current Sensor

    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.

  • Page 19: Auxiliary Inputs

    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)).

  • Page 20: Outputs

    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.

  • Page 21: Trip Coil Output

    24 V DC to 600 V DC 24 V AC to 440 V AC The trip coil output is the main output of the D1000, and activates in less than 1ms when a trip condition is detected. The trip coil output is based on an IGBT transistor that is able to carry 10 A AC or DC for a limited time.

    Inhibit Inhibit input is active or the current sensor is inhibiting trips. Fast flashing The D1000 has detected an arc (light), but the inhibit input or the current sensor is blocking a trip Short flashing Circuit check failed. Check the wiring of the input, or use the USB configuration tool to disable circuit check.
  • Page 23 D1000 is online, active and operational. The output will trip if a trip event is detected. Short flashing D1000 is in online mode, but has at some point detected an error. The front panel LEDs which is also short flashing tells where the error is. D1000 is off or in service mode Service D1000 is in service mode.
  • Page 24 Test On, green Online mode: The sensor is configured for use as a trip sensor. Otherwise the LED indicates that the D1000 is booting. If this condition remains after booting, it indicates unit error. Slow flashing If the Service-diode is flashing, the D1000 is awaiting manual confirmation of the connected sensors (see 14.1)

  • Page 26: Configuration

    The PC application for configuring the D1000 is built into the D1000 firmware and is pre-installed on the internal drives. When connected to a compatible PC using a USB cable, the internal drives of the D1000 are presented in the Windows file manager – similar to accessing the drives on a USB mass storage device.

  • Page 27: Connecting To The Pc

    D1000 Manual 12.1 Connecting to the PC When a USB cable is inserted, D1000 will go into service mode and arc detection is suspended. D1000 remains in this mode until the USB cable is detached. When connected to a PC the D1000 implements a “USB key”-like feature (USB Mass storage) and two drives will appear in your file manager.

  • Page 28: Description Of The Configuration Tool

    D1000 Manual 12.2 Description of the configuration tool The configuration tool is saved on the configuration drive of the D1000. The configuration tool will open in the web browser. It is not necessary to install any programming software on the PC.

    This is the pre alarm level for the arc detection. Adjustment in % of light intensity at trip level (trip level is adjusted on the front dial of D1000). Above example means light intensity >75 % of trip level will give alarm (sensor indicator LED green flashing).

  • Page 32: Sensor 1

    A1100 personal point sensor None (input disabled) Sensors with cable monitoring (A1000 and A2000) are automatically recognized by D1000 once they are connected. Therefore A1000 and A2000 do not need to be configured. If sensors without cable monitoring are used (A0100/ A0200) they must be chosen otherwise D1000 generates sensor fault for the respective input.

  • Page 33: Configuration Of Current Sensor

    SELCO A/S D1000 Manual 12.6 Configuration of current sensor 12.6.1 Setup Scaling of Current transformer This is the adjustment of the rated current of the secondary side of the current transformer. Note: Momentary Current Values This scaling is using the momentary value (not the RMS value) Most people are used to RMS values.
  • Page 34 No tick mark in the check box if the over current protection is to be disabled. Short circuit protection When enabled, the D1000 can trip the C/B on short circuit, without presence of an arc fault like a normal short circuit relay.
  • Page 35 Over current protection trip level The over current protection trip level is expressed in % of rated current. If this function is enabled and the over current level is exceeded for the duration of the time delay, D1000 will trip the circuit breaker.

  • Page 42: Commissioning

    14 Commissioning The D1000 will work out of the box, and will always trip if a sensor input exceeds the limit shown on the front, no matter if the circuit check is proclaiming the cable to be broken. However, we recommend doing a few simple tests on the sensors to ensure that problems on the sensors or cabling will be detected and reported.
