Circuit identification and status of each breaker may be displayed.

The Liebert LDMF detects and annunciates by alarm message the following conditions:

•

Overvoltage

•

Undervoltage

•

Neutral Overcurrent

•

Ground Overcurrent

•

Phase Overcurrent

•

Phase Overcurrent Warning

•

Summary Alarm

All alarm thresholds for monitored parameters are adjustable by way of the LDMF DB-9 setup port to match site
requirements. The factory setpoints for the alarms are as follows:

•

Overvoltage—At least one of the line-to-line voltages e6% of nominal.

•

Undervoltage—At least one of the line-to-line or line-to-neutral voltages falls below -13% of nominal.

•

Phase Overcurrent Warning—Current exceeds 75% of breaker amps.

•

Phase Overcurrent—Current exceeds 80% of breaker amps.

•

Neutral Current—Current exceeds 95% of breaker amps.

•

Ground Current—Current exceeds 5A (15-125kVA); 10A (150-225kVA).

Summary Alarm

•

Summary Alarm—Detects and annunciates any alarm.

Summary Alarm Contacts

•

The CPM has a Form C (one NO and one NC) summary alarm contact for remote alarm status. The contacts are rated at
24VAC @ 1A. The contacts change state upon occurrence of any alarm including warnings and resets when the alarm is
cleared. Summary alarm contacts are located on the adapter board. The adapter board is on top of the monitoring
enclosure. See

Figure 19

for details.

Communication—Liebert IntelliSlot

™

cards provide customer connections to a Building Management System

(BMS) or Remote Monitoring Systems. The following cards are available:

•

IS-WEBS Card provides SNMP/WEB output. An RJ-45 connector is supplied for customer connection to Ethernet LAN.

•

IS-485S Card provides Modbus 485 output. A terminal strip is provided for two-wire connection.

•

IS-IPBMS Card provides Modbus IP output. An RJ-45 connector is supplied for customer connection.

•

IS-UNITY-DP Card provides 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

Up to three cards can be plugged into the Liebert IntelliSlot

™

ports provided with the Liebert LDMF system.

If communication to Liebert SiteScan

®

is required, customer connection can be made to the adapter board

RS-485 terminals on TB1; see

Figure 19

for details. The adapter board is on top of the monitoring enclosure.
