1 Product Overview
1.2.2 Distance-Read Leak Detection
When the LD5200’s circuitry measures a current in excess of the user-defined leak threshold,
the unit’s microprocessor computes the distance to the leak. The LD5200 then annunciates the
leak and logs the alarm in its event log. The leak is communicated via email/Modbus/SNMP/
BACnet/SMTP/4-20mA to an equipped monitoring system. The relay output sends
notification to an alarm panel or monitoring system.
1.2.3 User Configuration and Communication
All the functionality needed to operate the LD5200 as a stand-alone device is accessible from
the LCD touch screen. Virtual buttons line the right side of the screen. Press the button for the
task you want to perform, and the screen for that task is displayed. Avoid using a pen or other
sharp object to activate the buttons on the LCD. This will damage the display.
The web-based user interface provides more extensive configuration options and allows users
to create an interactive map - a graphical representation of the monitored environment and
leak detection equipment. This web interface can be used on site or remotely via network
communications.
Digital fault and leak relay outputs and a 4-20mA relay output and allow the LD5200 to
interface with third-party management systems. The LD5200 also provides Modbus outputs
via EIA-485, twisted-pair wire, or TCP/IP, as well as BACnet/IP or BACnet/MSTP, SNMP,
and SMTP outputs.
