INTRODUCTION
The Liebert Liqui-tect Monitoring System is the ultimate in leak detection and retrofitting
capabilities for computer rooms and other large areas. The Liqui-tect Monitoring System provides
direct-read at the control unit location, as well as the ability to communicate with the Liebert
SiteScan Web enterprise monitoring system or a building management system.
The Liebert Liqui-tect Monitoring System features an easy-to-use liquid crystal display (LCD) panel
with readout of normal and alarm conditions, as well as leak location. Display and measurement
modules are contained in a single compact package.
The Liebert Liqui-tect Monitoring System can monitor up to 10,000 ft. (3048m) of Liebert LT500Y
leak detection cable. Points along the cable may be mapped by one person, making it easy to configure
within the critical space and pinpoint the location of leaks when they occur. The system determines
the location of the water on the detection cable and reports the distance from the Liqui-tect panel in
feet or meters. To ensure proper protection, the system continuously monitors operation, signaling
system normal, leak detected and cable fault.
The Liebert Liqui-tect panel offers these and other features to protect your installation from leak
damage:
•
•
•
•
•
•
•
•
audible and visual alarms
adjustable sensitivity setpoints for leaks and contamination
continuous scrolling of data
history logs
connection to a building management system
automatic detection of broken cables and contaminated cables
password protection
retention of configuration after a power failure
Two interfaces permit easy access and configuration of the Liqui-tect panel:
• LCD on the front of the enclosure
• Liebert’s SiteScan® Web enterprise monitoring system through a dedicated connection port
1.1
Equipment Inspection
Upon arrival of the unit, inspect all items for visible and concealed damage. Damage should be
immediately reported to the carrier and a damage claim filed with a copy sent to Emerson Network
Power® or to your sales representative.

Outside Enclosure Overview
The enclosure for the Liebert Liqui-tect panel’s controller board comes in two sizes:
• The large enclosure is designed to accommodate the Transformer Module and future
components, in addition to the controller board.
• The small enclosure is built to hold the controller board only.
Both enclosures are 2-3/4" deep.
Both enclosures have a built-in liquid crystal display (LCD) and a key lock, as shown in the example
below. The metal enclosures accommodate secure conduit fittings and protect components against
external forces and debris.

INSTALLATION
2.1
Installation Considerations
The Liebert Liqui-tect panel must be installed indoors and may be mounted on the surface of a wall or
flush-mounted, depending on the user’s application and the type of wall the unit will be mounted on.
The unit’s location must meet the following criteria:
• The panel must be placed close enough to the areas to be monitored to permit proper connection of
the leak detection cable. The panel will monitor two zones; each zone can accommodate up to
5,000 ft. (1524m) of leak detection cable.
• The Liebert Liqui-tect panel should be mounted where it can be easily accessed. Personnel would
access the unit through the LCD on its front cover or through Liebert SiteScan®.
• The site also must have electrical service and must permit connection of the panel’s four digital
outputs, two inputs for leak detection cables and two analog outputs for connecting to a building
management system or external alarm.
• The wall material must be capable of supporting the weight of the Liebert Liqui-tect panel: see
7.0 - Specifications.
NOTE
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.

Connecting Leak Detection Cable Inputs
The leak detection cable inputs are found on the lower right side of the Liebert Liqui-tect panel’s
printed wiring assembly board. There are two terminal blocks for the inputs; the lower terminal block
is for the Zone 1 cable and the terminal block above it is for a second leak detection cable, Zone 2.
To determine the proper wire size, see Table 4 - Wiring specifications.
NOTE
Each terminal block is a removable, two-part assembly to permit easier connection of more
than one input at a time. If making multiple connections, grasp the upper portion of a block
and pull firmly to the right until the assembly pulls apart.
After making the connections, push the removed piece back into the portion attached to the
printed wiring assembly until the terminal block pieces lock together.
3.1.1

Connecting Leak Detection Cable to the Connection Cable
The connection cable has a black fitting on one end that will fasten securely to the fitting on one end
of the leak detection cable—see Figure 8. Push these ends together, being careful to insert the
protruding ends of the leak detection cable into the holes in the connection cable connector. Twist the
connector ring to securely link the cables.
NOTE
Make sure the male end of the LT500Y leak detection cable is installed close enough to the
Liebert Liqui-tect panel to reach the fitting on the CONNECT10 connection cable.

After making this connection, lay the leak detection cable around the area to be monitored.
The monitored area would include any equipment or objects that might be damaged by water.
Figure 9 shows one possible layout. In the example, the detection cable crosses between air
conditioning units and computers to alert personnel when the electronic equipment is threatened by a
leak. If there is a liquid source in the ceiling, the cable can be placed there. If a raised floor is used for
cooling, the cable can be placed underneath the raised surface.

Follow these steps in laying the detection cable:
1. Attach the end terminator to the last length of leak detection cable required to monitor the
selected area.
2. Verify power is connected and test the detection cable by touching the detection cable with a
clean, moist cloth or paper towel.
If the cables are connected properly, the audible horn should sound and the LCD screen should
flash. Dry the detection cable to remove the alarm condition. (A hair dryer can be used to speed up
the drying.)
Note: Do not try to saturate the detection cable for testing! It requires only a small amount of
water to alarm. The detection cable will have to dry for the alarm condition to clear.

3. Once the cable passes the test, lay it in the pattern desired. Pay special attention to the following
cable placement precautions.
DETECTION CABLE PLACEMENT PRECAUTIONS
• Do not use detection cable that is damaged or dirty—for example, from plaster, spackle or debris.
• Detection cable should not be dragged through contaminants (dirty or greasy areas). Floor must be clean
for the detection cable to function properly and for the hold-down clips to adhere to the floor surface.
• Careful consideration should be taken to place detection cable out of the direct discharge airflow path of
environmental equipment. This type of equipment can discharge moisture into the airflow. Place cable
6 ft. (1.8m) from discharge to avoid nuisance alarms during humidification.
• Tools or heavy objects can do permanent damage when dropped, rolled, or set on the detection cable.
Avoid foot traffic on the detection cable as well.
• Do not use any type of adhesive tape to secure the detection cable.
• Do not allow soldering or welding near the detection cable without providing protection from heat and
contaminants. (Also avoid installing the detection cable in or near these type of areas.)
• Mild dishwashing liquid can be used to clean the detection cable of many contaminants.
4. Install the hold-down clips in pairs, as shown in Figure 10, with the following considerations:
a. The adhesive used to install the hold-down clips must NOT come in contact with the detection
cable.
b. One pair every 6 to 8 ft. (1.8-2.4m) in straight patterns (see Figure 11).
c. One pair every 3 to 4 ft. (0.9-1.2m) in circular patterns (see Figure 12).
d. One pair at the beginning and end of the arc when turning 90 degrees (see Figure 13).
e. One pair as needed to maintain consistent uniform contact between the floor and detection
cable.

Connecting Alarm Outputs
The Zone 1 and Zone 2 alarm outputs, found in the top right corner
of the Liebert Liqui-tect panel, provide a contact output for a leak
and a cable break for each zone. As an example, the outputs may
provide alarms to an auxiliary alarm panel or building
management system. To determine the proper wire size, see Table
4 - Wiring specifications.
A wiring key beside each terminal block indicates whether the
connected output is wired for Normally Open (NO) or Normally
Closed (NC).

Specify Longest Cable Length
You may specify the length of the longest cable connected to either of the 4-20mA alarm outputs. The
default value is 0-1000 ft. (0-304.8m). Valid entries range from 0-500 ft. (0-152.4m) to 0-5000 ft.
(0-1524m), as shown in the Maximum Cable Length screen, below right.
Select the longer cable length installed on either zone. For example, if Zone 1 has 2000 ft. (609.6m) of
cable and Zone 2 has 3500 ft. (1066.8m), select 0-4000 ft. (0-1219.2m).
The chosen setting applies to both zones and is correlated to the 4-20mA output of each zone to
provide the distance of the leak. Once the range is selected, the following correlation will be applied:
5mA = 0 ft. (0m)
19mA = 4000 ft. (1219.2m)
Table 10 shows the operation of the 4-20mA outputs.

Following are some similarities and differences between Latched and Unlatched alarms.
Liebert Liqui-tect System’s Response to Alarms - Both Latched and Unlatched
When a leak or cable break is detected:
• An alarm occurs,
• A record is created in the Alarm History Log and
• The leak-detected or cable-break alarm output contact changes state.
Latched Alarms Only
The user must reset latched alarms before another leak or cable break alarm can occur.
NOTE
A contaminated cable alarm will never latch. Because this type of alarm serves only as a
warning, it allows leak or cable break alarms to occur.
Unlatched Alarms Only
When an alarm output returns to its normal state, the alarms automatically clear and the system
returns to normal.
If two leaks occur simultaneously on the same cable, the system creates a record with the distance of
the first leak and displays an average distance for the two leaks. Always check the Alarm History Log
(see 5.2 - View Alarm History) when leak detected alarms occur in unlatched mode.
6.6
Setup System - Setup Re-Alarm Delay
The re-alarm delay may be set to provide an audible, reminder alarm notification after an alarm has
been silenced. The timer begins when the original alarm is silenced; the reminder alarm will occur
after the specified delay time has expired. The default setting is 5 minutes. The delay time ranges
from 0 to 999 minutes.
To set up the re-alarm delay:

Setup System - Setup Mapmode
Mapping involves measuring the exact location of various points along the leak detection cable. This
greatly simplifies the use of the Liebert Liqui-tect Monitoring System to quickly pinpoint the location of
a leak. The Liebert Liqui-tect Monitoring System determines the location of a leak by computing its
distance along the leak detection cable. By setting off alarms with a damp paper towel or sponge and
marking each reading on a map of the floor, you can define various points along the cable for later
reference in finding a leak. Up to 254 points can be mapped.
NOTE
You must perform the automatic calibration steps in 6.3.4 - Auto Calibration before mapping
can commence. The leak detection cable is 12 in. (30.48cm) to 18 in. (45.72cm) longer than the
nominal length, which allows a service loop should the cable need to be replaced. Automatic
calibration enables the Liebert Liqui-tect system to determine the cable’s exact length.
After the leak detection cable has been laid and properly connected, as described in 3.1 - Connecting
Leak Detection Cable Inputs, follow these steps to map the system:
1. Draw a floor plan that shows the routing of the leak detection cable, including any jumpers used
(non-sensing cable).
2. Using the LCD on the front panel of the Liebert Liqui-tect Monitoring System:
Log In and Choose Setup System

describing its location (for example, “at front of chiller”).
Wrap a damp paper towel or sponge around the selected point on
the cable to cause a short in the cable and trigger an alarm.
After about 30 seconds, the Liebert Liqui-tect panel annunciates a short beep. The LCD displays
the computed distance to the leak.
Remove the paper towel and dry the cable. In approximately 20 seconds, the Liebert Liqui-tect
panel annunciates a long beep indicating the short has been removed.
Go to the next point and repeat this process (steps 3 through 6) until the entire cable has been
mapped. Up to 254 points can be mapped.

In the View Last Map mode, the Liebert Liqui-tect panel shows the
mapped distance to a particular point along the leak detection cable,
identifying each point with an entry number that corresponds to point
“X” (where X represents 1 for the first point, 2 for the second, and so
on).
The user may view the entry number for point “X” and see the
corresponding distance to that point. This may be used either to
record that distance on the floor map or to verify the distance already
recorded on the map.
When a leak occurs, the Liebert Liqui-tect Monitoring System
displays the distance of the leak. By referring to the final floor map,
you can easily determine the location of the leak.
