User Guide: LD5000 Chapter 1: Product Overview

CHAPTER 1: PRODUCT OVERVIEW

1-1 DESCRIPTION

The LD5000 is a complete monitoring system that detects and reports the presence of water and other conductive liquids. The LD5000 couples RLE distance read leak detection cable with an advanced control panel. Each LD5000 monitors up to 5,000 feet of leak detection cable. When a conductive liquid comes in contact with the water leak detection cable an alarm sounds and the distance to the leak is shown on the LD5000’s four line display.

The LD5000 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 LD5000.

1-2 OPERATION

When the LD5000’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 LD5000 produces an alarm in the following conditions:

• Leak Detected

• Cable Break

• Loss of Communications

The LD5000 is a supervised system - it continually monitors the cable for continuity. A cable break or excess contamination of the cable causes a cable break indication and activates a relay.

1-3 MECHANICAL DESCRIPTION

The LD5000 with LCD is built with three circuit boards:

• The display board is connected to the microprocessor board with a ten conductor ribbon cable. The

display board is mounted on the inside of the unit’s door.

• The microprocessor board is mounted on top of the leak detection board. A reset switch is

provided to reset the microprocessor without cycling power to the unit.

1-4 INSTALLATION

The LD5000 with LCD is a wall mounted device. Before applying power to the unit, insure that all connections are correct and all screw terminals are secure. The EMI suppression core must be installed on the leader cable that exits the LD5000 to conform to CE standards.

1-5 FLOOR MAP

Users may purchase a water leak detection cable reference map with their LD5000. Once all the water leak detection 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.

User Guide: LD5000 Chapter 3: Installation

CHAPTER 3: INSTALLATION

3-1 INSTALLING THE UNIT

The LD5000 is a wall mounted device. To secure the device to the wall, first remove the aluminum back panel and all electronics from the enclosure. There are knockouts on the top and bottom of the enclosure designed to accommodate .5” conduit. Remove as many as necessary. There are two holes in the top back of the unit spaced 10.5” apart. Use drywall anchors to secure the unit to the wall. Put two more drywall anchors through the two holes in the bottom back of the unit. Reinstall the back panel and reconnect the electronics.

3-2 CONNECTING THE WATER LEAK DETECTION CABLE

The LD5000 is packaged with a 15’ length of leader cable. One end of this leader cable connects into the LD5000. This end of the cable is finished with a terminal connector. The other end features a mating connector which connects with the leak detection cable. The end of the cable is finished with a removable end terminator.

Attach (clip) the plastic EMI Suppression core to the 15’ leader cable. The plastic core should slide freely once it is placed on the cable. Make sure the core is located close to the end of the leader cable that attaches to the LD5000 terminal block connection (TB2). Connect the 15' leader cable with the EMI Suppression core to the LD5000; plug the terminal connector into the cable interface terminal block TB2. From left to right, with the screws of the connector facing up, the wires that screw into the terminal connector should be colored white, black, green, and red. If the terminal connector is removed from the end of the cable, make sure the wires are in this same order when the connector is reapplied. Once the leader cable is plugged into the terminal blocks, it is ready to be connected to the leak detection cable. To do this, unscrew the end terminator from the end of the leader cable. Attach the first length of water leak detection cable to the leader cable. Route the water leak detection cable according to the cable layout diagram, if provided. Lay the cable according to the following guidelines. Secure the end terminator on the unoccupied end of the leak detection cable.

Figure 3-1 Water Leak Detection Cable

3-2.1 Securing Cable to the Floor

Secure the cable to the floor with either J-clips or one of the other approved methods shown in Figure 3-2 Cable Installation Methods. J-clips are the manufacturer’s recommended installation method and can be installed as follows:

• Place one J-clip every three feet along the length of the water leak detection cable and one at each

turn of the cable.

www.rletech.com 970.484.6510 9

Chapter 3: Installation User Guide: LD5000

• If the cable is installed over an obstruction, clip the cable on both sides, as close to the obstruction

as possible.

• Do not install the cable directly in front of an air conditioner. Allow a minimum of six feet

between the unit and the cable. If the cable is too close to the air conditioning unit’s air stream, the moisture from the humidifier may cause false leak readings. If the cable must be installed in front of an air conditioning unit, place the J-clips 12 to 18 inches apart.

NOTE:

3-2.1.1 Recommended Cable Installation

It is important to finish the end of the leak detection cable with the end terminator. If the end terminator is not present, a cable fault will register. Note any variances between the cable layout diagram and the actual cable installation.

User Guide: LD5000 Chapter 3: Installation

3-3 APPLY POWER TO THE UNIT

Once the leak detection cable is connected to the unit, power may be applied.

Warning!

• A dedicated circuit breaker must be provided in the building within

close proximity to the RLE unit and be clearly marked as the disconnecting device for this unit.

The LD5000 operates on 85-264VAC power. An AC power supply should be run to the location of the unit. Before applying power to the unit, make sure the AC breaker switch is turned off.

Once the power is turned off, strip the end of the AC supply so the three wires inside are exposed. Strip the end of each of the three wires and feed the end of the power supply into the LD5000 enclosure. The three wires must now be inserted into the terminal block in the lower right corner of the enclosure. As is labeled in the enclosure, the live power line is placed inside the left hand opening of the terminal block. The Earth ground line is placed into the terminal block’s center station. The neutral line is placed into the opening on the right side of the terminal block.

Once all the wires are placed inside the terminal block, tighten the three screws across the bottom of the terminal block until the wires are securely held in place. Turn the AC supply back on. Flip the LD5000’s power switch on to activate the unit. Wait approximately one minute. No alarm should be present.

On the LCD, enter the Status menu. Press Enter (↵) twice. The cable length is displayed. If this reading varies by more than ±5% of the actual length of cable installed, verify the installation.

Use the switch settings on page 8 to set the cable length scale for the analog 4-20mA loop. Set the clock, system name, relay configuration, feet/meters, LCD setup (re-alarm time, password), etc.

Wait at least 30 minutes before calibrating the LD5000. Calibrate the LD5000 through the front panel Setup Menu (page 14) or through the RS-232 configuration port System Configuration Menu (page 33). Auto calibration is recommended.

CHAPTER 4: 4-20MA OUTPUT TESTING

The LD5000’s 4-20mA output is loop powered and tested by the manufacturer. The manufacturer guarantees its performance upon delivery. Should the 4-20mA output need to be tested in the field, follow these steps. The following procedure is performed with the cable connected, unless otherwise indicated.

1. Remove the two position plug from TB3.

2. Remove any wires from the terminal and install a 200Ohm resistor to TB3-2. Then apply

+24V to TB3-1 and ground of the 24V supply to the other side of the resistor.

3. Reinstall the plug on TB3.

4. With the system on and no alarms present, measure the DC voltage across the resistor. A

value of 0.8VDC should register. This equates to 4mA, or normal operation.

5. Remove the water leak detection cable and wait for the unit to activate its cable trouble alarm.

Measure the DC voltage across the resistor. A value of approximately 4.0VDC should be measured. This equates to 20mA, or a fault alarm. Reconnect the water leak detection cable.

6. Place water on the end of the water leak detection cable. Measure the DC voltage across the

resistor. The value will be proportional to the length of cable set on the dip switches. A value of approximately 3.8V, which equates to 19mA, will be read if the length of the cable is identical to the length set by the switches. Dry the cable.

7. Place water on the start of the cable. Measure the DC voltage across the resistor. A

measurement of approximately 1.2VDC, or 5mA, should be measured. This corresponds to a leak at zero distance. Dry the cable.

8. Remove the resistor from the plug and reattach any wires as necessary.

CHAPTER 8: MAPPING THE CABLE

After the water leak detection cable is laid in the desired configuration, the cable can be mapped. Mapping the cable improves the accuracy of the LD5000 and makes it easier to locate a leak.

The LD5000 computes the distance from the control panel to the leak along the length of water leak detection cable attached to the unit. In most cases, the water leak detection cable is laid in a curved or serpentine pattern. This may make it difficult to locate a leak when given a linear distance. To help alleviate this problem, identify a series of easily accessible, evenly spaced points along the cable length. Number the points, and record their locations on the leak detection reference map. Refer to the directions below and use the numbered points to map the cable. Then, when the unit detects a leak, the location of the leak can be determined by comparing the distance shown on the control panel with the known positions along the cable as recorded on the reference map.

NOTE

The system must be calibrated prior to mapping.

8-1 MAPPING DIRECTIONS

1) If a reference is not provided by RLE Technologies, create a drawing that represents the floor

plan. This drawing must include the room layout (walls, doors, and other permanent structures), the water leak detection cable routing path and any jumper sections of non-sensing cable.

2) Physically identify points along the cable routing path. The points should be easily accessible and

evenly spaced. Number the points and record their location on the reference map.

3) Using the front panel of the LD5000:

• Select System and press Enter (↵).

• Select StartMap and press Enter (↵).

• Select Accept to start mapping and press Enter (↵).

4) To test, wrap a damp paper towel or sponge around the cable at one of the previously mapped

points. The LD5000 produces a short beep within approximately 30 seconds. The LCD displays the LD5000’s calculated distance to the leak. Remove the paper towel and dry the cable. Within approximately 20 seconds, the LD5000 produces a long beep indicating the short is removed and the system has returned to normal.

TIP

If the individual mapping the cable is not in a position to hear the audible alarm, wait two minutes between each point. This ensures the s

stem has had time to stabilizer.

5) Go to the next point and repeat the above steps until all points along the cable are mapped and

tested.

6) When mapping is complete, press any key on the LD5000 to exit the mapping mode. This

LD5000 displays Mapping Mode Off. Press any key again to save the map and return to the System Menu.

www.rletech.com 970.484.6510 21

Chapter 8: Mapping the Cable User Guide: LD5000

g

7) Select ViewMap on the LCD and record the LD5000’s reading next to each point on the reference

map.

8) Mount the leak detection reference map alongside to the LD5000 control panel or the remote

display. When a leak or cable break occurs, refer to the map and the distance displayed on the LD5000 to determine the physical location of the leak.

Loss of power will cause all mappin

data to be lost.

Option 7 accesses the LCD Setup Menu. This section is applicable only if the unit has an LCD.

On the submenu, option 1 allows the alarm to be set as latched or unlatched. A latched alarm will display on the interface until it is manually cleared (audible alarm silenced). An unlatched alarm will disappear from the display as soon as the alarm condition is gone.

Option 2 on the submenu allows a user to set a re-alarm time. This is the amount of time that elapses between annunciations of the same alarm. If the re-alarm time is set at five minutes, the unit will alarm every five minutes as long as the alarm condition is present. The factory default value is “0” (disabled).

Option 3 exits the LCD Setup Menu and returns the user to the System Configuration Menu.

12-9 MAPPING MODE - 9

Option 9 displays the LD5000 Mapping Mode Menu. The mapping mode establishes a relationship between a known physical location, such as a position on a floor map, and a distance reading as displayed by the LD5000. Mapping is performed after all the cable is installed, the system is calibrated, and the cable’s end-of-line-terminator is in place. Mapping makes locating a leak annunciated by the LD5000 much easier.

12-9.2 Begin Mapping - 2

Menu selection 2 begins the mapping process. Physically identify and mark points on the floor map. The points should be easily accessible and somewhat evenly spaced. Number the points and record their location (their distance from the control panel) on the reference map.

Short the cable at these points using a damp paper towel or sponge. Once you short a point, wait for the leak to be detected - annunciated by a long (3 second) beep. Remove the short and wait for the all clear signal - annunciated by a short (1 second) beep.

Mark the points on the reference map with the distances as measured by the LD5000. Once the cable is mapped, select option 1 from the Mapping Mode Menu to view the new map.

Appendix A: Modbus Communication User Guide: LD5000

APPENDIX A: MODBUS COMMUNICATION

This document describes the Modbus communications protocol as supported by the LD5000 Water Leak Detection System. It includes details and information on how to configure the LD5000 for communications via Modbus network.

A-1 IMPLEMENTATION BASICS

The LD5000 is capable of communicating via the half-duplex RS-485 serial communication standard. The LD5000 is configured to act as a slave device on a common network. The RS-485 medium allows for multiple devices on a multi-drop network. The LD5000 is a slave only device and will never initiate a communications sequence.

A-1.1 Modes of Transmission

The Modbus protocol uses ASCII and RTU modes of transmission. The LD5000 supports only the RTU mode of transmission, with 8 data bits, no parity and one stop bit. Every Modbus packet consists of four fields:

• Slave Address Field

• Function Field

• Data Field

• Error Check Field (Checksum)

A-1.1.1 Slave Address Field

The slave address field is one byte in length and identifies the slave device involved in the transaction. Valid address range is between 1 and 254. Dip Switch #1 sets the address. The firmware program constantly reads dip Switch #1. Any changes are updated on the fly. Close the SW1 positions that correspond to the binary number of the address.

A-1.1.2 Function Field

The function field is one byte in length and tells the LD5000 which function to perform. The supported functions are 03 (Read 4xxxx output registers), 04 (Read 3xxxx input registers), 06 (Preset single register) and 16 (Preset multiple registers).

A-1.1.3 Data Field

The data field of the request is a variable length depending on the function. The data fields for the LD5000 are 16-bit registers, transmitted high order byte first (big-endian).

A-1.1.4 Error Check (Checksum) Field

The checksum field lets the receiving device determine if the packet has transmission errors. The LD5000 RTU mode uses a 16-bit cyclic redundancy check (CRC-16).

A-1.2 Exception Responses

If a Modbus master sends an invalid command to the LD5000 or attempts to read an invalid register, an exception response is generated. The response packet will have the high order bit of the function code set to one. The data field of the exception response contains the exception error code.

Table 1: Exception Codes

Code Name Description

01 Illegal Function The function code is not supported 02 Illegal Data Address Attempt to access an invalid address 03 Illegal Data Value Attempt to set a variable to an invalid value

A-2 PACKET COMMUNICATIONS FOR THE LD5000

A-2.1 Function 03: Read Output Registers

To read the LD5000 parameter values, the master must send a Read Output Registers request packet. The Read Output Registers request packet specifies a start register and the number of registers to read. The start register is numbered from zero (40001 = zero, 40002 = one, etc).

User Guide: LD5000 Appendix B: Bootloader Firmware V1.2

APPENDIX B: BOOTLOADER FIRMWARE V1.2

The LD5000 Bootloader firmware resides in EPROM and provides three basic services (a permanent code, diagnostic commands and the ability to update firmware).

B-1 PERMANENT CODE

The Bootloader firmware provides the LD5000 with a permanent start up code that cannot be erased.

B-2 DIAGNOSTIC COMMANDS

It also provides some basic diagnostics for the hardware.

• CLOCK - Displays the Clocks Date & Time for 5 seconds

• TIME - Displays the Time; May be set with “TIME HH:MM”

• DATE - Displays the Date; May be set with “DATE MM/DD/YY”

• ERASE PRGM - Erases the Flash Main Program

• LOAD PRGM - Loads the Flash Main Program – ASCII transfer

• LOAD XMODEM - Loads the Flash Main Program – Xmodem-1k transfer

• RUN - Runs the Flash Main Program

• BLANK - Blank checks the Flash Memory

• ID - Displays the Flash Main Program Revision

• VPP - Displays the Measured Flash Programming Voltage

• VPP ON - Turns on the Flash Programming Voltage

• VPP OFF - Turns off the Flash Programming Voltage

• NET ON - Turns the 485 Network On

• NET OFF - Turns the 485 Network Off

• DIAG - Starts the Diagnostic Test

• TST DSW - Returns the State of the Dip Switches

• DISP485 - Diagnostic that Displays the RS-485 Port Communications

• CLS - Clears the Terminal Screen

• WD - Stops the Internal Watchdog

• “?” - Displays the List of Valid Commands

B-3 UPDATING THE FLASH FIRMWARE.

The Bootloader firmware is used to update the Flash firmware. Firmware updates can be uploaded via the RS-232 configuration port at 9600 baud (N, 8, 1). Connect a terminal emulator to the configuration port at 9600, N, 8, 1.

To start the update process, wait for the ten second delay window during power up and press any key to stop the Flash Main Program from executing. Or if the Flash Main Program is already running, type “EX” to exit.

The Flash Main Program must be erased before an upload can be preformed. To erase the code, type the “ERASE PRGM” command. After a second or so, the screen will display “OK”.

www.rletech.com 970.484.6510 77

Appendix B: Bootloader Firmware V1.2 User Guide: LD5000

Next, type the “LOAD XMODEM” command. This will upload the new firmware file using X-Modem1k protocol. The file must be binary with a .bin extension.

After the file has been uploaded, enter the “RUN” command, or power down the LD5000 and then turn it back on.

User Guide: LD5000 Appendix C: Preventive Maintenance

APPENDIX C: PREVENTIVE MAINTENANCE

Follow these steps monthly to test the system and ensure that the control panel is functioning properly:

1) Place water on the cable.

2) Verify the Leak Detected alarm on the control panel.

3) Compare the distance reading on the LD5000 LCD to the reference map to verify that the LD5000

displays the correct leak location.

4) Dry the cable and verify that the LD5000 returns to normal.

5) Remove the end-of-line terminator.

6) Verify the Cable Break alarm on the control panel.

7) Reinstall the end-of-line terminator.

8) Verify that the LD5000 returns to normal.

Monitor the cable current monthly to verify that the cable is not being contaminated. The LD5000 will alarm on cable contamination if the contamination is excessive.

1) From the LD5000 display, press the “Enter” key until the cable current is displayed.

2) Be sure the cable current is less than 25uA. If the cable current is greater than 25uA, RLE

recommends troubleshooting the cable to determine which cable is contaminated. The contaminated cable should be removed, cleaned, retested and reinstalled.

Appendix D: Troubleshooting User Guide: LD5000

APPENDIX D: TROUBLESHOOTING

Trouble Action

Control Panel will not Power Up

Unit Powers Up without Displaying Characters on LCD

1) First verify the power on switch is in the on position.

2) Check with a DVOM (multi-meter) for AC input power on the lower

right and terminal block. Voltage should between 110VAC and 120VAC. If no AC power is present at terminal block, check the circuit (breaker) the LD5000 control panel is powered by. If voltage is present, go to step 3.

3) Check for 24 VDC at terminal block TB1 pins 2 and 3. If no voltage is

present across these pins, the internal power supply has failed. Contact RLE Technologies for replacement. If voltage is present and no LED’s are illuminated, contact RLE Technologies for further troubleshooting.

1) Open the front door and verify that the red/black supply wires are

connected to TB1 on the display board (LCD panel).

2) Check the R2 contrast Potentiometer located on the top middle section

of the display board. The dial should be turned clockwise until bottomed out. If the display is still not working, go to step 3.

3) Check the power on LED located to the left of the R2 contrast

Potentiometer. If the DS1 power LED is illuminated but no read out is on the LCD, contact RLE Technologies for further support. If the DS1 power on LED Is not illuminated check for power with a DVM at TB1 pins 2 and 3. Voltage should be 24VDC +/- 3 VDC. If no voltage is present there may be damage to the control wiring, contact RLE Technologies for further support. If voltage is present at terminal block, contact RLE Technologies for a replacement board.

Cable Break Alarm

80 970.484.6510 www.rletech.com

1) Power down the control panel and verify that the leader cable from the

water leak detection cable run is plugged into terminal block TB2.

2) Verify that the end-of-line terminator is installed on the end of the

orange sense cable run. If present at the end of the cable run, go to step

3.

3) Remove the end-of-line terminator from the end of the cable run and

install it onto the end of the leader cable coming from the control panel. If the condition clears, there is a damaged/faulty section of water leak detection cable. Start moving the end-of-line terminator to the end of each section of water leak detection cable to isolate the faulty section. If the condition does not clear, go to step 4.

4) Power down (shut off) the control panel. Remove terminal block TB2

from the logic control board. Remove the four conductors from the leader cable wire going into the four pin terminal block. Install a jumper wire between pins 1 and 2 and another jumper wire between pins 3 and 4. Reinstall the terminal block back into TB2. If the cable break condition clears, there is a problem with the leader cable. If the condition does not clear, contact RLE Technologies for further support.

User Guide: LD5000 Appendix D: Troubleshooting

Control Panel not Calculating Proper Length of Cable

Control Panel not Calculating Proper Leak Distance

1) First verify the proper wiring order into terminal block TB2. Wiring

color code should be as follows from left to right: White, Black, Green and Red.

2) Go into calibrate in the setup menu on the LCD display. Enter the total

footage of sense cable (orange) on the system and calibrate. If the condition does not change, please contact RLE Technologies. The control panel is pre-calibrated from the factory. The overall footage should be within 5% of actual installed length.

1) Check the distance on the cable run to verify that the control panel is

monitoring. Verify there is no water along the cable run. Check to see if multiple leaks are present on the cable. The first leak should be read and latched by the system; however, if the system is updated or simultaneous leaks occur (2 or more) within 30 seconds of the initial leak, the system may display the average distance (distance of the first leak + distance of the second leak / 2). If no water is present, go to step

2.

2) Power down (shut off) the control panel and remove the end-of-line

terminator from the end of the sense cable. Disconnect the first section of cable from the LD5000 control panel, where it joins to the second section of cable. Install the End-of-Line terminator at the end of the first section of sense cable. Turn power back on at control panel. Once the control panel runs for five to ten minutes, use a damp cloth, rag or paper towel and place it on the end of the orange sense cable. If the leak is calculated correctly, remove the end-of-line terminator; reconnect the sense cable and move down to the next section of cable. Repeat this process until a faulty reading is obtained. If the reading is off at the first section of cable, please contact RLE Technologies for support.

Cable Contamination Alarm Unit Displays: “Cable Contaminated @ XXXX Ft”

NOTE

Contamination and/or physical damage to the cable is not covered under warranty. For all other troubleshooting concerns and questions regarding this product, contact RLE Technologies.

1) To clear a contamination alarm, the cable must be removed and

cleaned. Usually the cable can be cleaned by pulling it through a clean damp rag.

2) If the cable is contaminated by oil, Glycol or chemicals, the cable can

be washed. Use a mild detergent solution of 1 capful to 2 gallons lukewarm water (<105°F). Agitate the cable in a suitable container, rinse with clear lukewarm water and wipe dry with a clean towel. The cable may also be cleaned by wiping it down with Isopropyl Alcohol.

3) Retest the cable by connecting it to the LD5000 before reinstalling it

under the floor.
