    The output’s direction of rotation is as follows: the signal goes in the even pin and out from the odd pin (see the image below, as detailed in the device’s side sticker). NOTICE! TICE! The high-speed outputs are polarity-sensitive. © Arcteq Relays Ltd IM00009...

  • Page 20: Trip Relays

    Whenever the device detects a system error or the auxiliary power supply is disconnected, the SF relay changes its state. The state stays this way until the device returns to a healthy condition. See the System self-supervision chapter for more information. © Arcteq Relays Ltd IM00009...

    AQ-07 is an arc light fiber optic loop sensor, which is a robust fiber optic cable with a practically unlimited bending radius. The sensor contains hundreds of glass fiber drains covered by a plastic tube, thus making it extremely strong and durable. Fiber sensors are distributed through the protected switchgear cells. © Arcteq Relays Ltd IM00009...

  • Page 24: Arc Light Fiber Optic Loop Sensor Aq-08

    If necessary, the ends of an AQ-07 cable can be ordered with heat shrinking tubing to avoid light detection outside the protected zone. The covered area can be one (1) or two (2) meters by default; if other lengths are required, please consult the Arcteq sales team. You can find the Contact and reference information page at the end of this manual.
