    LCD Interface 5.9. Zone Setup The Zone Setup menu will display a table of configured zones. A zone is a set length of cable that may have a name or description assigned to it. Upon alarm, if a leak distance falls within a zone’s boundary, the zone's description will appear on the main screen.

  • Page 40: Point Mapping

    When using the leak detection master option, the LD5100 relays can be activated according to the slave unit alarm. If the slave has a leak alarm or a cable break alarm, the LD5100 leak or cable relay will change state, respectively (i.e. it will trigger that an alarm is present. The zone will then appear on the LCD and an alarm state will be reported to the top level of the system.

  • Page 41: Mapping The Cable

    The LD5100 computes the distance from the control panel to the leak along the length of SC cable attached to the unit. In most cases, the SC cable is laid in a curved or serpentine pattern.

  • Page 42: Mapping Directions

    To test the map, wrap a wet paper towel or sponge or pour a small puddle of water around the cable at one of the previously mapped points. The LD5100 produces a short beep within approximately 30 seconds. The LCD displays the LD5100's calculated distance to the leak.

  • Page 61: Leak Detection Modbus Master

    ASTER HAPTER This feature allows the LD5100 to act as a Modbus master, so it can talk to other RLE distance read panels. Up to 11 RLE distance read panels can be connected to the EIA-485 port#1 on the LD5100. The system status can be viewed by using the view zones menu. The LD5100 will display leak, cable break, cable contamination, and loss of communications alarms from the slave units connected to it.

  • Page 62: Configuring The Ld5100 Via The Local Display (Lcd)

    RLE recommends generating alarms from each panel to ensure proper communication. You can configure the LD5100 relays to change state according to the slave unit alarm. If the slave has a leak alarm or a cable break alarm, the leak or cable relay, will change state, respectively.
