2.0 PRODUCT OVERVIEW

The Liebert LDMF monitors the main panelboard circuit breaker and individual panelboard branch circuit breakers. The measurements are used to report the voltage, current and alarm conditions for each breaker. The Liebert LDMF utilizes branch circuit sensor modules and individual current transformers (CT) to monitor current. In addition, the Liebert LDMF monitors options like subfeed and output circuit breakers and provides a full array of power parameters and alarms.

The Liebert LDMF is available as an option for the Liebert PPC™, Liebert FDC™, Liebert FPC™, Liebert RX™and Liebert RDC™.

The Liebert LDMF system can communicate with a Building Management System (BMS) and Liebert SiteScan® Web via optional Liebert IntelliSlot™ cards or Liebert SiteLink® interface.

The Liebert LDMF consists of a monitor board, interface board, optional local display and Branch Sensor Modules (BSM).

The Liebert LDMF is capable of receiving input from current branch sensor modules. The sensor module (BSM) contains 100A current transformers (CTs) encapsulated in an epoxy-filled plastic enclosure designed to be mounted next to the panelboard. Sensor modules are designed to work 3/4" or 1"-spaced panelboards. If a sensor module CT fails, connections are provided for up to six replacement CTs. The optional CTs can be attached directly to the load cable feeding the failed CT.

Higher-rated CTs may be used for monitoring optional subfeed circuit breakers. For subfeed breakers, such as main panelboard breakers, the Liebert LDMF monitors not only the three-phase current but also the ground and neutral current. These subfeed circuit breakers are in addition to the panelboard circuit breakers that can be monitored through the BSM. The Liebert LDMF can accommodate 18 individual large current transformers.

If your Liebert power center is supplied with a Square D® I-Line™ panelboard, the Liebert LDMF can monitor it as well as its output breakers. A PM4 Large Interface Board (PLIB) replaces the panelboard PM4 Interface Board (PIB) and can monitor up to 42 CTs. Each PLIB can monitor eight four-wire or five-wire I-Line and/or subfeed breakers including ground and neutral current. There are two (2) PLIBs per monitor board that can monitor up to 16 five-wire I-Line and/or subfeed breakers.

The Liebert LDMF system includes three Liebert IntelliSlot ports for remote communication. Optional Liebert IntelliSlot cards can provide the following remote communications:

• IS-WEBS card for SNMP/WEB with RJ-45 connection to Ethernet LAN

• IS-485S card for Modbus 485, 2-wire connection

• IS-IPBMS card for Modbus IP, with RJ-45 connection to Ethernet LAN

• IS-UNITY-DP card for HTTP/HTTPS, Vertiv Protocol, e-mail, SMS, SNMP v1/v2c/v3, BACnet IP/MSTP and Modbus TCP/RTU output using a serial RS-485 two-wire connection

In addition to Liebert LDMF remote communications, an optional local display offers easy-to-use viewing of electrical data for various branch breakers as well as alarm details such as the type and source of each alarm.

3.0 MAJOR COMPONENTS

3.1 PM4 Monitor Board (PMB)

The PM4 Monitor Board (PMB) is the main processing and storage circuit board. The PMB contains the non-volatile memory where the configuration file is stored. The CT Module Assemblies will connect directly to the PMB via the 4 ribbon cables connectors. The PMB is a DSP-based logic controller with internal flash memory to store breaker configuration, alarms and energy data. The on-board battery supplies power to the real-time clock.

All the electrical parameters are accumulated on the PMB for processing to Liebert Velocity protocol for remote monitoring and the HMI interface for the local display. Kilowatt-hours (kWh) data is accumulated on this board for the panelboard mains, subfeeds and each branch circuit breaker. A remote command can be used to reset the accumulated energy data.

Additional PMB Capabilities

• Six (6) auxiliary CT connectors, which allow for replacing a failed CT.

• A DB9 serial port on the outside panel is available for local configuration.

3.2 PM4 Interface Board (PIB)

The Liebert LDMF PM4 Interface Board (PIB) provides connections for the voltage and currents of the panelboard main circuit breaker as well as the CT current for any installed large branches or subfeed breakers (maximum of 18 CTs).

For the large branches or subfeed breakers, the nine CTs on the A side of the board are normally associated with the A-side voltages for power calculations. The B-side CTs are normally associated with the B-side voltages. A cross-configuration tool allows changing that association for subfeeds.

Vertiv™ | Liebert® LDMF™ Distribution Monitoring User Manual | 4

Page 9

The 18 large branch CT inputs can also be used to monitor up to three subfeed circuit breakers. This is configured using the configuration tool (see 5.5 - Using the Configuration Tool). The CTs from the B side of the PIB are cross-configured to the A side so that the three subfeeds appear within the A-side panelboard register space. The 18 large branch breakers require CT’s with 1A secondary.

WARNING

Before connecting a large CT to the PIB, note the CT MUST have a 1A secondary. Connecting

anything other than a 1A secondary CT will damage the PIB and the CT. To ensure the proper current ratio and accuracy, the CTs should be purchased through

Vertiv. See Ta bl e 1 for details. Contact your local Vertiv representative or call Vertiv Support at 800-543-2378.

3.4 Branch Circuit Monitoring Sensor Module (BSM)

The Branch Circuit Monitoring Sensor Module (BSM)—more commonly referred to as the CT Module—contain 21, 27 or 36 individual Current Transformers filled inside an epoxy enclosure. Each load circuit is passed through one of the openings for branch circuit current monitoring. The signals leave the CT module via a ribbon cable which is connected directly to the PM4 Monitor Board (PMB) for attenuation and processing.

There are two BSM designs depending on the manufacturer of the panelboard installed:

• Utilize 1" spacing between circuits.

• Utilize 3/4" spacing between circuits.

NOTE

The diameter of each CT hole is 0.433" (11mm). Wire diameter and thickness of insulation must be taken into account before wiring each branch circuit. Using wire that is too large may prevent the conductor from fitting through the CT hole. Do not attempt to alter the diameter of the CT opening.

For larger panelboards, the CT Module is designed to interlock to maintain alignment between the breaker poles and the CT Modules.

3.5 Power Supply With EMI Filter

The power supply assembly converts 100-240VAC (+10%/-13% range) 50/60Hz into 12VDC to provide logic level power for the PMB.

The Power Supply is fed from the line side of the panelboard main breaker. If during normal operation the panelboard main breaker trips or is turned off, the PMB will still have power to communicate alarms via the local display or remotely via Liebert IntelliSlot® cards.

The LDMF allows users to view the panelboard circuit data locally through the optional display. The user interface has function keys to scroll through and view each panelboard's data as well as the associated branch circuits and/or subfeeds.

Along with the branch circuit data the LDMF Display also has an alarm annunciation window that lists all active alarms. The display has an LED status indicator that changes to red in the event of an alarm. The Silence/Reset button will silence the audible alarm when pressed once and held until alarm is silenced. When pressed a second time, the button clears the alarm and turns off the red LED.

Alarm thresholds cannot be added, deleted or adjusted on the local display. These functions may be performed only by using the LDMF Configuration software, which is available for download at the Liebert Web site. Refer to 5.3 - Downloading the Software for downloading instructions and see 5.5 - Using the Configuration Tool for details on using the software.

3.7 PM4 Adapter Board

• The PM4 Adapter Board (PAB) is provided with each Liebert LDMF. The PAB is typically mounted on the back of the display, which is located on the front door of the unit. The PAB provides a customer interface to the LDMF summary alarm contacts.

• If two Liebert LDMF systems are provided, the two PABs are connected to each other at the factory. It is only necessary to connect to one PAB to monitor the Customer Summary Alarm; the two Liebert LDMF units share summary alarm contacts.

• On the Liebert FPC and Liebert PPC the PAB has additional connections on TB1 that include Remote Emergency Power Off (EPO). The field-selectable switch S1 on the PAB allows the selection for either Manual or Auto restart. The factory default setting is Manual.

• Manual restart allows for an orderly supervised startup after power failure. The control circuit automatically energizes the shunt trip mechanism of the main input breaker upon sensing output voltage failure.

• Setting the switch to Auto deactivates the manual restart. In Auto restart mode, the main input breaker does not trip due to power failure and the unit will restart when power is restored.

NOTE

The TB1 connections for customer alarms 1 - 5 are used only with the VPMP product.

4.0 INSTALLATION

WARNING

Dangerous voltages exist in power distribution units and power conditioning units. To ensure maximum safety, all circuits breakers in the panelboard should be removed of power and the input feeder breaker should be turned Off and locked-out in accordance with NEC and local/state code.

NOTE

Liebert LDMF components and any other monitoring devices should be installed only by properly trained and qualified personnel.

This section provides instructions for installing and connecting Liebert LDMF current transformers. If any Liebert LDMF component requires service, contact Vertiv Support at 800-543-2378 for assistance.

4.1 Installing a BSM (CT Module Assembly)

In most cases the BSM—the CT Module—is factory-installed and no further work is required. If a CT Module must be added, it attaches easily to the side of a panelboard to monitor any combination of 1-, 2- and 3-pole circuit breakers.

• For side-by-side panelboards (21 circuits on each side), attach one CT Module to each side of the panelboard, ensuring that the center of the CT hole lines up to the branch circuit breaker connection.

• For Square-D Inline panelboards (42 circuits in a row), the two CT second, lower CT Module so that the two cutout sections line up, then attach the screws to secure the CT Modules to the panelboard.

• For GE Inline type panelboards, the two CT Modules fit end to end. Flip the second, lower CT Module so that the 50-pin ribbon cable connector, mounted on the bottom of the CT Module, lines up with the hole in the panelboard mounting bracket.

Install the circuit breakers according to the manufacturer's documentation. Route the circuit wire through the center of the CT and attach securely to the circuit breaker.

4.1.1 Connecting Panelboards A and B

The CT Module connects to the PMB via a 50-pin ribbon cable attached to the back of the CT Module. Route the ribbon cable and attach to the appropriate connector (see figure at right).

There are four connectors that are labeled for easy identification: two for Panelboard A (A1 and A2) and two for Panelboard B (B1 and B2).

• Connect the CT module that will monitor Circuits 1-21 to the A1 or B1 connector, depending on whether the CT Module is monitoring Panelboard A or B.

• Connect the CT module that will monitor Circuits 22-42 to the corresponding A2 or B2 connector.

4.2 Installing a Solid-Core Current Transformer

WARNING

A solid-core CT cannot be installed on a wire while current is flowing through the wire. Damage to the burden resistor and CT will occur. Power must be removed before installing and/or removing any CT. CT’s should be installed only by properly trained qualified electricians.

The CT for the panelboard main input circuit breaker is hard-wired to the connectors. Removing CT wires from the connector requires a pin extraction tool.

Contact Vertiv Support at 800-543-2378 for assistance.

NOTE

When replacing or installing a CT, ensure that the replacement CT has a secondary rating of 1A— for example, 100:1, 200:1, 500:1 or 1000:1. Using a higher-rated CT—for example, 100:5 or 500:5will damage the burden resistors on the PIB board.

Typically the three-phase and neutral wires utilize a CT rating of 100:1, 200:1 500:1 or 1000:1, while the ground wire utilizes a CT rating of 100:1.

Route the circuit wire through the core of the CT and wire-tie the CT to the cable. Refer to the manufacturer's documentation for proper orientation to ensure accurate readings.

NOTE

When installing CT’s for a large branch circuit breaker or subfeed, verify which monitoring board is installed.

• A PIB can support up to three subfeeds,.

• One LIB can support up to eight output and/or subfeed breakers.

• Two LIB boards are provided to support up to 16 output and/or subfeed breakers.

Vertiv™ | Liebert® LDMF™ Distribution Monitoring User Manual | 11

Page 16

4.3 Installing a Current Transformer on the PIB Interface Board

If subfeed breakers are ordered with the unit, the phase, neutral and ground CTs are wired to the Interface Board.The CTs will be zip-tied inside the equipment for the electrician to install on each conductor when the conductors are wired to the subfeed/large branch breaker. The ground and neutral CTs for each factory-supplied subfeed or large breaker are factory-installed and wired. CTs have a white or H1 that depicts how to position the CT on the cable to ensure accurate readings. The white dot or H1 must face toward the source when installing the CT on the phase cables. The neutral conductor CTs are placed in the opposite direction, with the marking faced toward the load. Route the conductors through the core of the CTs and wire-tie the CT to the cable to ensure the CT stays in place.

If subfeed breakers are installed in the field, up to five CTs may be installed (three phases, neutral and ground). The neutral and ground CTs may be omitted if monitoring of neutral and ground is not required. The 5-wire CT kits will be shipped separately and grouped together with each CT with a label indicating whether it is a phase CT, neutral CT or ground CT.

There are two 18-pin terminal blocks on the Interface Board for large branch circuit breakers and/or subfeeds-one for Panelboard A and one for Panelboard B.

The circuit board is marked with a triangle to indicate Pin 1. Pin 1 should be used for the white wire of CT1 (Phase A). The black wire should be connected to Pin 2. The same pattern will follow for the remaining CTs.

After all CTs are installed, use the Configuration tool to label and set alarm parameters. To configure the Liebert LDMF, see 5.5.11 - Add a Circuit Breaker.

If the Power Distribution Center is supplied with optional isolated ground, the isolated ground circuit can be monitored by the Liebert LDMF. Usually the CT is already installed and wired to the Large Branch Terminal Block at the factory. If not, perform the following steps:

(For Isolated Ground CT Installation only)

• Connect the isolated ground CT to Pins 17 and 18 on the two 18-pin terminal blocks on the Interface Board.

• Connect the isolated ground CT white wire to Pin 17 and the CT black wire to Pin 18.

Refer to the following example and Tab le 2 for wiring configuration details. Example: When installing a subfeed breaker where the three phases, neutral and ground will be

monitored, the CTs should be wired as follows:

Vertiv™ | Liebert® LDMF™ Distribution Monitoring User Manual | 12

4.4 Connecting a Current Transformer to the PM4 Large Interface Board (PLIB)

PLIB can monitor eight 4-wire or 5-wire output/subfeed breakers. Two LIB boards are provided to support up to 16 output and/or subfeed breakers. If subfeed breakers are ordered with the unit, the phase CTs are installed and wired to the PLIB. The neutral and ground CTs are also factorysupplied and wired to the PLIB as required.

CTs have a white dot or H1 marking that depicts how to position the CT to ensure accurate readings. The white dot or H1 marking must face toward the load when installing the CT on the ground and neutral cable. The phase CT's are placed in the opposite direction, with the marking faced toward the source. Route the neutral and ground cable through the core of the specified CT and wire-tie the CT to the cable.

If subfeed breakers are installed in the field, up to five CTs may be installed to monitor a subfeed breaker (three phases, neutral and ground). The neutral and ground CTs may be omitted if monitoring of neutral and ground is not required.

The designators on the PLIB are different from those on the Interface Board.

• CT1 (Phase A white wire) begins on TB1 CT1+ and the black wire connects to CT1-.

• The Ground CT for the first subfeed/output circuit breaker connects to TB4 CT35.

The designators on the PLIB are different from those on the Interface Board.

• CT1 (Phase A white wire) begins on TB1 CT1+ and the black wire connects to CT1-.

5.1 Alarms

The Liebert LDMF constantly monitors electrical data for each breaker and subfeed. When the unit detects an alarm condition, it annunciates and displays alarm messages via the Monitor program (see 5.4 - Using the Monitor Tool (Used Only for Startup and Diagnostics)) as well as showing the alarm on the local display (if installed).

Alarms must be manually reset after the alarm condition has been corrected and may be reset through Modbus or by pressing the alarm Silence/Reset button on the front display assembly.

To facilitate troubleshooting:

• All alarms are stored in non-volatile memory to protect against erasure by a power outage.

All alarm thresholds for monitored parameters are adjustable by using the Configuration tool to match site requirements (see 5.5 - Using the Configuration Tool).

Tab le 7 shows the types of alarms for the various types of breakers, along with a description, factory default setpoints and allowable range for each.

7.0 TROUBLESHOOTING / FREQUENTLY ASKED QUESTIONS

1. How do I obtain the software necessary to monitor and configure the Liebert LDMF?

• The software package is available from the Liebert Web site, www.vertivco.com. Under Service and Support, choose Software Downloads.

• Click on the link for the LDMF - mm/yyyy Toolkit:

where mm/yyyy is the month and year of the update—for example, 08/2016 or 11/2016

Note: There are two versions of Liebert Distribution Monitoring software. Be sure to select the LDMF version, which is for units with a setup port labeled LDMF Setup.

Do NOT choose the Liebert Distribution Monitoring (LDM) Tool Kit. (The LDM Tool Kit is used on units with a setup port labeled LDM Setup.)

• Save the file to a desktop or laptop computer (PC) and extract the contents.

NOTE

The software may be updated and changed without any notification. Check the Web site regularly to ensure the software is up-to-date.

2. What is contained in the downloaded software package?

• The flash program with a walk-through instruction

• The configuration program

•The monitor program

3. What should I do if the BMS is reporting an overcurrent alarm?

• Verify the circuit is not actually overloaded.

• Using the Configuration program, verify that alarm setpoints and the CT ratio are correct.

• If settings are correct, verify that the BMS is operating correctly.

• If the issue still exists, contact Vertiv Support at 800-543-2378 for assistance.

4. I get an error message “Incorrect Schema Version” when I try to run the Monitor tool or Configuration tool. What should I do?

• Ensure that only one program—either Monitor or Configuration—is running at a time. You can’t run both programs at the same time.

• Contact Vertiv Support to ensure correct tool for the firmware.

• Verify the PC is connected to the LDMF Setup port and the communication cable (F-F null modem DB9) is fully seated (see 5.2.1 - LDMF Setup Port Connection).

• Verify the Liebert LDMF unit has power (green LEDs on the BCB will be flashing).

5. How can I make a backup copy of the configuration file?

• Connect to the external LDMF Setup port (see 5.2.1 - LDMF Setup Port Connection).

• Run the configuration program (see 5.5.1 - Starting the Configuration Program).

• At the bottom of the Configuration window, select Save to File. Navigate to a location on your PC to store the file (see 5.5.5 - Save the Configuration File to Disk).
