CHAPTER
CHAPTER 0PRODUCT OVERVIEW
1.1. Description
The LD5100 is a complete monitoring system that detects and reports the presence of water
and other conductive liquids. The LD5100 couples SeaHawk Water Leak Detection Cable
(SC) with an advanced control panel. Each LD5100 monitors up to 5000 feet (1,524m) of SC
cable. When a conductive liquid comes in contact with the SC cable an alarm sounds and the
distance to the leak is shown on the LD5100's LCD front panel display.
The LD5100 allows a single person to perform the mapping of the cable - the process of
determining the relationship between a known point along the cable and the value as measured
by the LD5100.
1.2. Operation
When the LD5100's analog circuitry measures a current in excess of the user-defined leak
threshold, the unit's microprocessor computes the distance to the leak. The unit then
annunciates the leak and logs the alarm in its event log. The leak relay and fault relay each
have two outputs. An additional 4-20mA output allows the device to interface with third party
management systems.
The LD5100 is a supervised system - it constantly monitors the cable for continuity. A cable
break or excess contamination of the cable causes a cable break indication and activates a
relay. The LD5100 sends alarm notifications to predetermined recipients when an alarm
sounds. The LD5100 produces an alarm in the following conditions:
Leak Detected
Cable Break (or Cable Fault)
Cable Contamination
Loss of Communications

1Product Overview
1.3. Mechanical Description
The LD5100 is built with two circuit boards:
The display board is connected to the main board with a 20 wire ribbon cable and two
power wires. The display board is mounted on the inside of the unit's door.
The main board is mounted inside and on the back of the enclosure. A reset switch is
provided to reset the microprocessor without cycling power to the unit.
1.4. Installation
The LD5100 with LCD is a wall mounted device. Before applying power to the unit, ensure
that all connections are correct and all screw terminals are secure.
1.5. Cable Reference Map
Users may purchase a Water Leak Detection Cable Reference Map (part # FM1114) with their
LD5100. Once all the SC cable is installed, compare this reference map with the actual cable
installation. Note any discrepancies and return the map to the original author for correction.
Keep a copy for use until the updated map can be reinstalled near the control panel.
1.6. LCD User Interface
The LD5100’s LCD is a 160x160 pixel resolution backlit display with a five button keypad.
The default password for the system setup is 1234. The interface's menu structure is as
follows:
Main Menu
– View Zones
– Cable Status
– Alarm History/Trend
– Alarm History
– Trend
– Erase Alarm History
– Erase Trend Log
Comm Port Status
View Map

Navigate through the menu(s) with the up, down, left and right arrows. Where indicated on
the LCD submenus, the left arrow navigates left on menus or cancels any action and returns to
the previous menu. The enter arrow selects a submenu and commits changes. Further LCD
interface information can be found in Chapter 5, “LCD Interface” on page 31.

CHAPTER
CHAPTER 0CONNECTIONS AND SETTINGS
The LD5100 is comprised of two boards. The two boards are accessed when the device's front
cover is opened. The display board is located on the inside of the door. The main board is the
large board on the left side of the enclosure.
Figure 2.1 LD5100 Main Board

www.rletech.com 20 970.484.6510
2Connections and Settings
2.1. Main Board
The connectors on the main board, found at the bottom of Figure 2.1, are labeled TB2 through
TB7. The connector on the power board is labeled TB3. The reset switch on the main board is
labeled SW1. The termination setting on the main board is labeled SW2.
2.1.1 SW1: Reset Switch
The Reset switch is provided to reset the microprocessor without cycling power to the unit.
2.1.2 SW2: Termination Setting
The Termination Setting switch must ALWAYS be set to the far right. This enables the RS232
port to work properly.
2.1.3 R39: Contrast
This adjustment knob adjusts the 160x160 LCD's contrast. Turn the adjustment knob
clockwise or counterclockwise to adjust the contrast as necessary.
2.1.4 TB1: Input Power
This is a factory wired two position connector with the following connections (for reference
only):
TB1-1 24VDC negative (-)
TB1-2 24VDC positive (+)
2.1.5 TB2 and TB3: RS485 Modbus Port 2 and 1
Terminals TB2 and TB3 connect to a RS485 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 RS485
ports are set to no parity, 8 databits, 1 stop bit (n, 8, 1). Connect the RS485 wires to TB2 or
TB3 on the main board as follows:
TB2-1 A (+)
TB2-2 B (-)
TB2-3 Shield
