The FG-NET-LL Digital Unit is designed to be used with TTK FG-OD range of Digital Sense Cables, for industry Long Line application. In the event of a fault on the sense cables (leak or cable break): Primary responses from the FG-NET-LL: - An audible alarm is triggered and a relay is activated. - The touch screen of the panel displays the location of the leak (to the concerned sense cable) and details of the fault (the type of fault leak or cable break), including the time and date the faul

FG-NET-LL

FEATURES

  • 7” (175mm) touch-screen gives a clear and detailed indication of the system status.
  • User-friendly system - users can customise the system with the sub menus accessible from the home screen, to set up the panel.
  • Up to 120 lengths of sense cables can be managed independently. The system’s reaction time to faults is adjustable cable by cable.
  • Temporal isolation (72 hours maximum) a or several sense cables.
  • Up to 5000 events stored in the history log.
  • Non-volatile memory (SD), for storing user settings and drawings.
  • Three types of interface for communication with a BMS available.
    - TCP/IP connection via an Ethernet port.
    - JBUS/MODBUS RS232 or RS422/485 serial links.
    - 9 relay contacts: 8 configurable relays + 1 specific relay for power
    interruption.
    • Dual relay drive (e.g. 1 for BMS and 1 for solenoid valve);
    • Relay positions are defined by a LED indicator.
    Different security levels to provide maximum security.

BENEFITS

  • Dynamic Leak Evolution Analysis - The magnitude of a leak and its evolution in time can be analysed through the alarm logs. The number and sequence of addressable sections which report a leak, together with their timestamp, allow to monitor the leak’s progression in time.
  • Precise location of a leak and cable break to the concerned sense cable.
  • Each sense cable is addressable and can be assigned a specific name.
  • Multiple simultaneous leaks can be detected (120 cables = 120 potential alarms).
  • When a cable break occurs, the system maintains its integrity by continuing to monitor all preceding cables for faults.
  • Compatible with existing monitoring systems (Trend DCS etc.)
  • Extension and upgrade of the system is easy.
