Introd uctio n 1 1.0 I NTRODUCTION The Liebert Liqui-tect Monitoring System is the ultimate in leak detection and retr ofitting capabili- ties for computer rooms and other large areas.
Introd uctio n 2 1.2 Out side Enclosure Overview The enclosure for the Liqui-tect panel’ s controller board comes in two sizes: •T h e large enclosure is designed to accommo date the Transformer Module and future compo- nents, in addition to the controll er board.
Introd uctio n 3 1.3 T ypical Sequence Figure 3 shows a typical se quence of how the Liqui-tect Monitoring System fu nctions afte r detecting a leak, conta mination or cabl e brea k in either Zone 1 or Zone 2. Responses depend on configuration settings.
Introd uctio n 4 1.4 Controller Board Overview The Liqui-tect panel’s co ntroller board, as shown be low, has connectors for two digital outputs for leak detection alarms, two digital out p uts for cable break alarms, two inputs for l e ak detection cables and two analog outputs for co nnecting to a building management sy stem.
Introd uctio n 5 H-S t a t u s L E D s Indicates the operation al status of the panel. 1.5: LED Indicators I - 4/20mA ou tput (Zone 2) Provides the distance liquid is detected, normal status and cable fault. Used to provide status to a building managemen t system or remote monitoring system.
Introd uctio n 6 1.5 LED Indicators The Liqui-tect pan el’s controller bo ard has LED in dicators that s how the status of inputs, ou tputs and other board components.
Installation 7 2.0 I NST ALLATION 2.1 Inst allation Considerations The Liqui-tect panel must be instal led indoors and may be mounted on the surf ace of a wall or flush- mounted, depending on the user’s appli cation and th e type of wall the unit will be mounted on.
Installation 8 2.2 Surface-Mounting th e Liqui-tect Panel After dete rmining where t o place the unit, check to ensure that yo u have all the hard ware required to install the panel on the surface of a wall.
Installation 9 2.3 Flush-Mounting the Liqui-tect Panel The Liqui-tect panel may be fl ush mounted accord ing to company practices—either with screws through the sides of the pa nel into wall supports or with hangin g hardware that attaches to the back of the pan el.
Installation 10 2.4 Connect Power to the Liqui-tect Panel The Liqui-tect panel requires 24VAC for proper op eration. Liebert recomme nds using the optional Transformer Module manufa ctured by Liebert or another UL-approve d Class 2 power uni t to obtain proper voltage.
Installation 11 2.4.2 Input and Output Power Connections - Large Enclosure Input Power Connections To connect el ectrical power to the Transformer Module: 1. Install electrical wi ring from util ity power to the Transformer Modu le. 2. Use copper wires only; prope r wiring to use fo r power is 14/2 A WG copper wire with ground.
Connection s and Configuration 12 3.0 C ONNECTIONS AND C ONFIGURATION Input and output connect ion s to the Liqui-tect panel may be made in any order—it is not n ecessary, for example, to ma ke all inpu t connections be fore making any output connections.
Connection s and Configuration 13 3.1 Connecting Leak Detection Cable Inputs The leak detection cable inputs are found on the lowe r right side of the Liqui- tect panel’s printed wir- ing assembly board.
Connection s and Configuration 14 3.1.2 Connecting Leak Detection Cable to the Connecti on Cable The connection cable has a black fitt ing on one end that will fasten se curely to the fitting on one end of the leak detection cable—see Figure 8 .
Connection s and Configuration 15 3. Once the cable passes the test, la y it in the pattern desired. Pay special attention to the following cable placement precautions. 4. Install the hold-down clips in pairs, as shown i n Figure 10 , with the following considerations: a.
Connection s and Configuration 16 3.2 Connecting Alarm Output s The Zone 1 and Zone 2 alarm outputs, found in the top right corner of the Liqui-tect panel, provide a contact outpu t for a leak and a cable break for each zone. As an example, the outputs may provide alarms to an auxili ary alarm panel or building ma nagement sys- tem.
Connection s and Configuration 17 3.4 RS422 SiteScan Web Connector The Liqui-tect panel will interfa ce wi th Liebert’s SiteSc an Web enterprise monitoring system. SiteScan can be used to monit o r the Liqui-tect panel from a host computer an d silence the a udible alarm.
Overview of Menus 18 4.0 O VERVIEW OF M ENUS The Liqui-tect panel displa ys the Opening Screen at startup, as shown in Figure 14 . If any alarms are active, the Current Alarm screen appears. (Pressi ng any key on the LCD keypad will silence the audib le alarm.
V iew Status Options 19 5.0 V IEW S TAT U S O PTIONS The View Status menu allows any user to view the st atus of cables in both zones, an alarm history log and a trend log for both zones. The arrows ↑↓ are used to scroll through the menu. The Enter ↵ key is used to select the menu item.
V iew Status Options 20 5.1 View Cable S tatus The Cable Status screens display th e overall status of the cable con- nected to each of the two zones moni tored by the Liqui-tect panel, as well as the length of the cable be ing monitored and the amount of cur- rent present in each cable.
V iew Status Options 21 5.2 View Alarm History The Alarm History Log contains up to 100 records of al arms that have occurred. Records are added to this log as alarms occur. To view t he Alarm Histor y Log: • From the Main Menu, use the arrows ↑↓ to choose View Status , then press Enter ↵.
V iew Status Options 22 5.3 View Zone T rend The Zone Trend Log contains up to 288 records that are recorded at regular intervals (every 24 hours) to assist us ers with verifying opera- tional and troubleshoot ing problems. Records are added the b eginning of the log as they occur.
System and Control Options 23 6.0 S YSTEM AND C ONTROL O PTIONS The System and Control menu allows you to config ure the Liqui-te ct panel—s etting up inputs and outputs and system featu res such as date and time.
