CHAPTER
CHAPTER 0PRODUCT OVERVIEW
1.1 Description
The LD5200 is a distance-read leak detection controller. It can operate as a stand-alone device
or connect to multiple RLE leak detection controllers through its Ethernet or EIA-485 ports.
When coupled with up to 10,000 feet (3084m) of RLE’s sensing cable, it reports the presence
of water and other conductive liquids. When a conductive liquid comes in contact with the
sensing cable, the following occurs:
♦ An audible alarm sounds.
♦ The distance to the leak is shown on the LD5200’s LCD touch screen and on the LD5200’s
web interface. An integrated reference map within the web interface will also show the
location of the leak.
♦ Notification is sent via email or Modbus/SNMP/BACnet/SMTP to a central control
location, such as a building management system (BMS).
1.2 Operation
1.2.1 Supervised System
The LD5200 is a supervised system - it continually monitors sensing cable, spot detectors, and
connected leak detection controllers for continuity and produces alarms for the following
conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
♦ Loss of communications

1Product 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.

2.2 Mount the LD5200
The LD5200 is a wall mounted device. Using the wall mount kit (included), mount the device
in a convenient location.
Figure 2.1 LD5200 Wall Mounting Kit
Once the unit is mounted on the wall, run conduit to the device to support your cabling needs.
2.3 Establish Physical Connections
The connectors for the LD5200 are accessible from the inside of the enclosure. Remove the
knock-outs on the bottom and top of the enclosure as necessary to accommodate conduit and
cabling.
The LD5200 is built with two circuit boards:
♦ The display board is mounted on the inside of the LD5200’s door, and is connected to the
main board with a multi-wire connector. The display is a color touch screen that enables
configuration and management from the front panel.
♦ The main board is mounted inside the main compartment of the enclosure. A power supply
and power switch are also mounted in this main compartment.
The connectors on the main board, shown in Figure 2.2, are labeled TB1 through TB7 and P1
through P3. Switches are labeled SW1 through SW3 and the Status LED is labeled DS1. The
image of the board has been rotated to accommodate labels.

2.3.1 TB1: 4-20mA Output
The 4-20mA analog output allows the LD5200 to communicate with a 4-20mA loop powered
output. This connection is provided on TB1. The maximum range (20 mA) can be set to 1000,
2500, or 5000 feet. Connect the 4-20mA wires to TB1 as follows:
TB1-1 4-20mA positive (+)
TB1-2 4-20mA negative (-)
2.3.2 TB2: Sensing Cable Interface
A 15-foot (4.57m) section of non-sensing cable is supplied with each LD5200. The leader
cable connects sensing cable to the LD5200, since sensing cable cannot connect directly to the
unit. Insert its four stripped wires into the appropriate slots in TB2 - from left to right: white,
black, green and red.
Figure 2.3 Cable Connection TB2
NOTE If the terminal connector is removed from the end of the cable, make sure the wires are in the
same order, W - B - G - R, when the connector is reapplied.
For further information regarding sensing cable, refer to “Connect the SeaHawk Sensing
Cable” on page 21.
2.3.3 TB3: Maintenance Relay
Maintenance reminders can be configured through the LCD or the web interface. This relay
(TB3) is activated once the scheduled maintenance period has lapsed. If you wish, connect this
relay output to a BMS or NMS to monitor regularly scheduled maintenance intervals.
2.3.4 TB4: Two Fault/Leak Relay Outputs
TB4 houses two Form C relay outputs. These relays provide alarm notification when a leak,
cable fault, or cable contamination is detected.
The top row of TB4 (pins 1 - 6) provides a connection to one of the leak alarm relay outputs
and one of the fault relay outputs; the bottom row of TB5 (pins 7 - 12) provides a second set of
contacts for the same leak and fault alarms.
TB2-1 White wire
TB2-2 Black wire
TB2-3 Green wire
TB2-4 Red wire

2Installation
Connect the alarm relay wires to TB4 as follows:
TB4-1 Leak alarm normally open (NO)
TB4-2 Leak alarm common (C)
TB4-3 Leak alarm normally closed (NC)
TB4-4 Fault alarm normally open (NO)
TB4-5 Fault alarm common (C)
TB4-6 Fault alarm normally closed (NC)
TB4-7 Leak alarm normally open (NO)
TB4-8 Leak alarm common (C)
TB4-9 Leak alarm normally closed (NC)
TB4-10 Fault alarm normally open (NO)
TB4-11 Fault alarm common (C)
TB4-12 Fault alarm normally closed (NC)
Both relays (all alarms) can be configured to be latched or unlatched. A latched alarm requires
a manual reset of the system once a leak or cable problem is no longer present; see “Leak” on
page 50 for configuration instructions.
2.3.5 P1: EIA-232 Connector
An EIA-232 connection allows the LD5200 to be connected directly to a terminal or PC. The
EIA-232 uses a baud rate of 9600. The EIA-232 port is set to 8 databits, no parity, and 1 stop
bit (8, N, 1). A straight through cable should be used to connect a terminal or PC to the
LD5200 via the EIA-232 connector. This connection should only be used by advanced users
for specialized operations, including advanced diagnostics, uploading firmware, and
troubleshooting.
2.3.6 SW1: TB5 Port 3 Termination Switch
The switch position numbered 2 on SW1, when switched on (down position), places a
termination resistor across the + and - terminals of the EIA-485 port. This is used when the
TB5 connection on the LD5200 is the last unit on a EIA-485 network. SW1, switch position 1,
is currently inactive.
2.3.7 TB5 and TB6: EIA-485 Modbus Ports
TB5 and TB6 connect to an EIA-485 network. A grounded shield contact is provided for
connection to shielded cable. If the shield contact is used, verify the power connector is
properly grounded and there is no voltage potential between units on the network.The EIA-
485 ports have a selectable baud rate (9600, 19200, or 38400) and are set to 8 databits, no
parity, and 1 stop bit (8, N, 1). Connect the EIA-485 wires to TB5 and TB6 as follows:
TB5, EIA-485 port 3
TB5-1 A (+)
TB5-2 B (-)
TB5-3 Shield
TB6 (top row) EIA-485 port 1

2.3.8 SW2: TB6 Port 2 (Bottom Row) Termination Switch
The switch position numbered 2 on SW2, when switched on (down position), places a
termination resistor across the + and - terminals of the EIA-485 port. This is used when the
TB6 (bottom row) connection on the LD5200 is the last unit on a EIA-485 network. SW2,
switch position 1, is currently inactive.
2.3.9 SW3: TB6 Port 1 (Top Row) Termination Switch
The switch position numbered 2 on SW3, when switched on (down position), places a
termination resistor across the + and - terminals of the EIA-485 port. This is used when the
TB6 (top row) connection on the LD5200 is the last unit on a EIA-485 network. SW3, switch
position 1, is currently inactive.
2.3.10 P2: RJ45 Network
This 10/100 BaseT Ethernet connection allows the LD5200 to be connected directly to a local
area network. Use a crossover cable (shipped with the LD5200; blue cable with yellow ends)
for initial connection and configuration. The default settings are as follows:
IP Address: 10.0.0.188
Subnet Mask: 255.255.255.0
Default Gateway: 10.0.0.1
2.3.11 P3: Optional Power Connection
If a mechanical failure causes the provided AC power supply and connections to fail, a wall
adapter can be plugged into P3 and used to power the LD5200. This option is provided for
temporary, emergency situations only, and is not intended as a permanent power solution.
2.3.12 TB7: Input Power (from Input AC Power Supply)
TB7 is a factory-wired two position connector with the following connections (for reference
only):
TB7-1 24VDC positive (+)
TB7-2 24VDC negative (-)
2.3.13 DS1: Status LED
A status LED is located at the top of the main board, and is labeled DS1. Indicators are as
follows:
Green - LD5200 is functioning properly
Red - LD5200 is in an alarm state
Yellow (flashing) - The LD5200’s bootloader is operational
