1.1 Supervised System

Liqui-tect LP6000 is a supervised system, which means that it continuously monitors for leaks and other
fault conditions, including a cable break and cable contamination, that trigger an alarm. When a leak or
fault is detected, a relay is activated, and LP6000 sends alarm notifications to predetermined recipients
via the configured communication method.

1.2 Distance-read Leak Detection

When the Liqui-tect LP6000 measures a current in excess of the defined leak threshold, the
microprocessor computes the distance to the leak, annunciates the leak, and logs the alarm in the event
log. The leak is communicated via the front-panel display and other configured notification methods.

1.3 Communication with Liqui-tect LP6000

The front-panel display is an LCDtouch screen with virtual buttons providing access to all functions of a
stand-alone unit.

A Web-based user interface (UI) provides access to system conditions and settings on-site or via network
communication.

In additon to the web-based UI, LP6000 communicates with external monitoring systems via the following
outputs:

• Modbus via EIA-485, twisted-pair wire, or TCP/IP

• BACnet/IP or BACnet/MSTP

• SNMP

• SMTP

2 PREPARATION
ANDINSTALLINGTHELIQUI-TECTSYSTEM

Installing the Liqui-tect system involves the following preparation before beginning:

• Choosing a readily-accessible location for the controller.

• Preparing the appropriate connections for power, leak detection, and communication.

• Consulting with your ITadministrator to determine the following network settings for the
LP6000 controller:

• IP address

• Subnet mask

• Default gateway

• Creating a leak-detection cable layout diagram that considers the equipment in the area that
may be damaged by water and the possible sources of leaks. Plan the cable layout to alert
personnel when electronic equipment is threatened by a leak. An example of a layout diagram
is included in Laying the Leak-detection Cable and Securing to the Floor on page 11.

Required Equipment and Supplies:

The following is included:

• Liqui-tect LP6000 controller

• CONNECT15 connection cable

• LT500-ET end terminator

• Screws and anchors for wall mounting

The following equipment is sold separately:

• Leak-detection cable(s) of chosen length, 15-ft, 35-ft, or 50-ft

The following tools may be field-supplied, if needed:

• Electric drill (to drive screws or drill pilot holes)

• Screw driver

• Marker/Pencil to mark screw locations

2.1 Mounting the LP6000 Controller on a Wall

1. In the location determined during preparation, mark the wall for the mounting holes using the
unit as a template.

2. If necessary, drill holes for the 4 screws that will secure the unit to the wall.

• If the wall material is not strong enough, use the supplied wall anchors.

• Clean up debris from drilling.

3. Install the 2 top screws, and hang the unit on the screws, allowing it to slip down so the screws
are in the smaller part of the pear-shaped slot.

4. Tighten the screws until snug.

5. Insert the remaining 2 screws in the bottom holes and tighten.

2.3 Laying the Leak-detection Cable and Securing to the Floor

Refer to the site layout diagram for your installation, an example is shown in the following figure, and route
the cable as indicated.

• The leak-detection cable may be placed in the ceiling if there is a liquid source to monitor.

• The cable may also be placed beneath a raised floor.

2 Leak-detectioncable (yellow)

3 Air- conditioning/Environmental units

4 Computer/Equipment rack

5 End terminator ( at end of leak-detection cable run)

Observe the following guidelines and precautions when installing the leak-detection cable:

• Do not use conductive materials, such as Fire Block or caulk, on the leak-detection cable.

• Do not use any type of adhesive tape to secure the leak-detection cable.

• Do not use a leak-detection cable that is damaged or dirty for example, from plaster, spackle or
debris.

• Do not drag the leak-detection cable through contaminants, such as dirt or grease.

• The floor must be clean for proper leak detection and for the hold-down clips to adhere. Use
isopropyl alcohol to clean the spots on the floor for the hold-down clips.

Vertiv | Liqui-tect LP6000 Installer/User Guide | 11

• Use careful consideration to keep the leak-detection cable's route from the direct path of
discharge air flow from air-conditioning or environmental equipment. If the cable is too close to
the air stream, moisture from the discharge may cause false leak readings. Route the cable at
least 6ft (1.8m) from discharge air flow to avoid nuisance alarms.

• Do not allow soldering or welding near the leak-detection cable without providing protection
from heat and contamination. Also, avoid installing the cable near these types of areas.

• The clip’s adhesive backing does not work well on porous concrete floors. We recommend using
a drop of silicone or another non-conductive adhesive to help secure the clip to the floor.

NOTE: If the leak-detection cable does become dirty or contaminated, refer to Troubleshooting on
page 77 for steps to clean the cable.

To install the cable:

1. Prepare the surface on which the leak-detection cable will be installed to avoid contaminating
the cable. Clean the entire floor as much as possible.

2. Lay the cable in the pattern and route depicted in the layout diagram, maintaining consistent,
uniform contact between the leak-detection cable and the floor.

Vertiv | Liqui-tect LP6000 Installer/User Guide | 12

3. Before inserting the cable in the clips, install the hold-down clips in pairs along the route as
shown in the following figure.

CAUTION: Do not allow the adhesive used on the hold-down clips to come in contact with the
leak-detection cable.

Figure 4.3 Hold-down clip installation

ITEM DESCRIPTION

1 Installclips inpairs.

2 On a 90-degree turn, install 1 pair atthe beginning of the arc and 1 pair at the end of the arc.

3 On s traights ections, install 1 pair every 6to 8 ft (1.8 to 2.4 m).

4 In a circular pattern, install 1 pair every 3to4 ft(0.9to1.2m).

4. Allow the adhesive for the hold-down clips to dry completely, then snap the cable into each
clip.

5. Make sure that there are no gaps between the floor and the cable, adding clips as needed.

6. If necessary, make adjustments to the cable-layout diagram to represent the cabling "as­installed." This diagram will be used to measure and map leak-detection landmarks when
testing the installation.

You are ready to connect the leak-detection cable to the controller. See Connecting the Leak-detection

Cable on page 14.

Vertiv | Liqui-tect LP6000 Installer/User Guide | 13

2.4 Connecting the Leak-detection Cable

The leak-detection cable does not directly connect to the LP6000 controller. The 15-ft connection cable
included with the system connects the controller to the leak-detection cable.

To connect the leak-detection cable to the controller:

1. With the screws of TB2 facing up on the controller, connect the 4, stripped, bare wires of the
connector cable to the terminal block in the following order as shown in the following figure.

• White

• Black

• Green

• Red

NOTE: If the cable is removed from the terminal connector, make sure that the wires remain in the listed
order when the connector is re-installed.

Figure 4.4 Connector cable and leak-detection cable connection to controller

ITEM DESCRIPTION

1 Connector cable (CONNECT 15)

2 Leak-detection cable

3 Endterminator (LT500-ET)

2. At the other end of the connector cable, unscrew the end terminator, and attach the male
connector of the leak-detection cable to the connector cable as shown in the figure above.

3. Attach the end terminator to the end of the cable run and to the end of each branch­connector branch.

NOTE: A cable fault will register on the controller display if the end terminator is not attached.

You are now ready to connect power to the controller. See Connecting Power to Liqui-tect on page 15.

Vertiv | Liqui-tect LP6000 Installer/User Guide | 14

2.5 Connecting Power to Liqui-tect

WARNING! Liqui-tect LP6000 requires a dedicated circuit breaker that is clearly marked as the
disconnection device for the [[[Undefined variable Liquitect.ModelNo]]] controller. Make sure
that the dedicated circuit break is off before connecting the AC power wires to the
[[[Undefined variable Liquitect.ModelNo]]] controller. Follow all state and local codes.

1. Engage a certified electrician to run an isolated power supply to the location of the unit.

2. Remove knockouts, as necessary, from the bottom of the unit, then route the power supply into
the enclosure to the power-input terminal block, and insert the wires a shown on the back
plate: Neutral - Line - Ground, see Input and Output Connectors on page 10.

3. Before applying power to the unit, make sure that all connections are correct and all screw
terminals are secure.

4. Apply power and wait approximately 1minute for the LP6000 to start up.
There may be alarms because the leak-detection cable is not yet connected.

5. Verify that power is connected, and verify that the leak-detection cable is working by touching
it with a clean, moist cloth or paper towel.
If the cable is properly connected, an audible alarm sounds and an alarm notification displays
on the digital display.

NOTE: Do not saturate the leak-detection cable for testing. A small amount of water triggers an alarm,
and the cable must dry for the alarm to clear.

6. Dry the cable to remove the alarm condition. Use a hair dryer to speed up drying if needed.

7. Once you verify that the leak-detection cable is working, you are ready to calibrate the cable,
map leak-detection points and test the installation. See Mapping and Testing the Installation
on page 16.

2.6 Calibrating Resistance to Cable Length

The leak-detection cable has a base resistance of 4 ohms/ft. Because of manufacturing variances, the
base resistance of each length of leak-detection cable may be slightly more or less than 4 ohms/ft, which
means that the displayed length may be slightly more or less than the actual length of the cable.

While a configuration using base resistance values is very accurate, you can fine-tune the resistance to
make it more precise to increase accuracy and bring the reported cable-length value in line with the
actual cable length.

To calibrate cable resistance:

1. Make sure that the LP6000 controller is powered-on, has all sensing cables attached, and that
there are no alarms.

2. Record the following data from the home page of the web UI:

DATA REC ORDED INFO

Cable lengthreported by L P6000.

Cable current

Leg 1 r esistance

Leg 2 res istance

Vertiv | Liqui-tect LP6000 Installer/User Guide | 15

3. Select Configuration > Leak Settings, and record the following from the Leak Configuration
page:

DATA REC ORDED INFO

Reportedr esistance per foot

4. To calculate the actual length of the cable: Add the physical length of the cable (the sum of all
of the lengths of installed cable) to the simulated length (the sum of all weighted lengths and
branch connectors installed), refer to the following simulated lengths when determining the
total simulated length.

• LT500-WL simulates 35 ft

• LT500-BC simulates 105 ft

• Jumper cable adds 0 (zero) ft

Calculate the actual length (physical length+simulated length) and record the result.

DATA REC ORDED INFO

Calculatedactual length of cable

5. Verify that the Cable Current recorded is less than 15 µA.

• If the reading is higher than 15 µA, clean the cable using isopropyl alcohol to remove any

contamination from installation.

6. Calculate the most-accurate resistance value by dividing the reported cable length by the
actual cable length and multiplying the quotient by the reported resistance.

7. On the Leak Settings page, enter the newly-calculated resistance-per-foot value and click
Submit Changes.
The reported cable length now more-closely matches the physical length of the cable and
thereby improves leak-detected reporting accuracy.

2.7 Mapping and Testing the Installation

NOTE: If the LP6000 controller is already to connected to a BMS or NMS, notify monitoring personnel
before beginning the test.

1. On the "as-installed" cable-layout diagram prepared after laying the leak-detection cable:

• Mark the cable routing, connection points, equipment used in and monitored by the
Liqui-tect system.

• Mark the locations where leak detection is critical and the locations at which the leak­detection cable changes directions. These will be the locations measured and mapped
during testing.

2. Before beginning, set the leak alarm delay to 5 seconds as follows:

• On the web interface, click Configuration > Leak Settings.

Leak Settings on page 37 opens.

• In Leak Alarm Delay, enter 5, then click Submit Changes.

3. At each marked location on the diagram, use one of the following methods to simulate a leak,
and record the reported distance on the diagram:

Vertiv | Liqui-tect LP6000 Installer/User Guide | 16

• Pour a small puddle of water on the cable while it rests on the floor.

• Dunk the cable in a cup of water.

• Soak a paper towel and wrap it loosely around the cable without putting pressure on the
cable.

NOTE: To avoid inaccurate readings, do not grip the cable with your hand.

NOTE: Dry the cable to remove the leak alarm.

4. Verify that the simulated leaks are reported within a few feet of their actual, physical location
based on the diagram.

NOTE: To fine tune the location of leak detections, see Calibrating Resistance to Cable Length on page

15.

5. When finished, remove the source of simulated leaks, reset the leak alarm delay, and return the
system to normal operation.
