Display and Mon itoring for MGE’s Pow erManagement Mod ule (PMM) and Remo te PowerManagement Mod ule (RPMM)

MONITORING OPTIONS

MGE’s Power Management Module (PMM) and Remote Power Management Module (RPMM) areavailable with four optional monitoring systems: the Multi-Circuit Monitor (MCM), the Circuit Monitor4000 (CM4000), the Power Meter 800 (PM800), and the DMMS300. All four monitoring systems areequipped with RS232 and/or RS485 serial communications. A stand alone web server / Ethernet gatewayis an option with two of the monitoring systems, multiplexing the data from multiple PMM/RPMMs and

placing it on an Ethernet network. The Ethernet cards also allow the PMM/RPMM data to be accesseddirectly over the internet without requiring a web server.

MULTI-CIRCUIT MONITOR (MCM)

The MCM provides detailed power information and can be configured to monitor the power both on theinput and output side of the transformer. When input monitoring is selected, all defined parameters aremonitored for the line and the load side of the transformer and displayed on a single LCD large formatdisplay. The MCM monitors all standard features on the PMM/RPMM except harmonics. The MCMcomes equipped with serial RS485 and infrared communications, and is designed to accommodateoptional features such as Main Circuit Current Monitoring, Branch Circuit Current Monitoring, andPanelboard Main Circuit Breaker Current Monitoring.

Features include:• Dry contact alarm output• Alarm log• IR port for downloading to Palm Pilot• RS485 serial output• True RMS values• Branch Circuit Monitoring (BCM) (optional)• Panelboard Main Breaker Monitoring (optional)• Web enabled• Nonvolatile Memory• Min/Max reading of values for real time readings• Set-Point controlled alarm & relay functions• Modbus Protocol• Password protected

• Input / Output Monitoring Option (optional with MCM only)

The MCM can be configured to monitor the power both on the input and outputside of the transformer. Note that when the PMM is used with the STS (PMM Plus configuration), the

STS will provide input power monitoring via its local display. Consult the MCM manual for details. Thisoption is not available with harmonic cancellation transformers.

• Panelboard Main Breaker Current Monitoring Option (optional with MCM only)

The Panelboard Main Breaker monitoring displays the current of the panelboard mainbreakers (panelboard main breakers or distribution breakers). In the event the currentapproaches the trip rating of the breaker, the monitor will alarm via the LCD display.Since the panelboard main breakers are rated at 225A and panelboards can potentiallyfeed in excess of 600A of branch circuit breakers, monitoring prevents accidental trippingdue to overloaded panelboards.

• Branch Circuit Current Monitoring Option (optional with MCM only)

The Branch Circuit Monitor (BCM) monitors individual current of all 42 branch circuitbreakers on a standard SQ-D panelboard. In the event the current exceeds a threshold(custom programmable via a PC on every pole for pre-alarm/summary alarm and vitalalarm thresholds), the alarm will be activated. Alarm parameters and currents areavailable via the MCM LCD display, serial output, or can be downloaded to a PDA viathe IR port on the MCM display (serial port is disabled if IR port is enabled).

Branch Circuit Monitor Manual

• EGX Ethernet Gateway Web Enabler Option

The EGX Gateway puts the MCM and BCM data on anEthernet network and web enables the data allowing it to beaccessed over the web without the addition of servers orcomplicated interface hardware. A number of PMM/RPMMsmay be daisy chained via their serial ports and linked to oneEGX monitor. The result is faster alarm notification,increased data transfer rates, and easy access to data usingonly a web browser. An open protocol means that otherdevices may be interfaced with EGX to web enable them, aswell.

Features include:• Remote configuration using a standard internet browser –

no special software required

• Step-by-step online setup pages – no instruction manualrequired• Small size makes installation into power equipment fast

and easy

Pow er Meter 800 (PM800)

The PM800 is a multifunction, digital instrumentation, data acquisition and control device. The PM800 canbe configured to display the output (load side) voltage, current, kVA, kW, frequency, and other parametersdefined below. All measured values are displayed on a large format LCD display.

Features include:• True RMS values• Nonvolatile Clock/Memory• Set-Point controlled alarm & relay functions• Min/Max reading of values for real time readings• Power quality readings• Dry contact alarm output• Alarm log• RS485 serial output• Password protected

PM800 Manual

DMMS300

The DMMS300 displays 23 instantaneous electrical parameters. Values for each parameter are accessedthrough the keypad on the meter’s front panel. The DMMS 300 displays four current measurements, sixvoltage measurements, seven power readings, and six parameters of total harmonic distortion. Allreadings are faceplate accessible. All measured values are displayed on a large format LCD display.

Features include:

• True RMS values• Output metering• Nonvolatile memory• Min/Max reading of values for real time readings• Power quality readings• Set-Point controlled alarm & relay functions• Dry contact alarm output• Alarm log• RS485 serial output (optional)• RS232 serial output (optional)• Modbus Protocol• Password protected

CIRCUIT MON ITOR 4000 (CM4000)

The CM4000 is intended for customers seeking a premium monitoring solution with virtually every

feature including harmonic analysis and waveform capture. The CM4000 can also be webenabled serving web pages directly off the monitor (no server or PC required) using the optionalEthernet Gateway Card (ECC). The CM4000 can be used in conjunction with the Branch CircuitMonitor (BCM) option, however it will not be possible to display local BCM alarms or locally vieweach branch breaker current. This information can be made available remotely via the BCM'sserial interface, or by integrating the BCM's serial output onto the CM4000 network. BothCM4000 and BCM data can be placed on an Ethernet network.

Features include:• True RMS values• Output metering• Branch circuit current monitoring (optional)• Waveform capture• Integrated Ethernet/web enabled output• Detailed harmonics monitoring• Nonvolatile memory• Min/Max reading of values for real time readings• Power quality readings• Set-Point controlled alarm & relay functions• Dry contact alarm output• Alarm log• Email on alarm• RS485 serial output• RS232 serial output (optional)• Modbus Protocol• Password protected

CM4000 Manual

• Ethernet Communications Card (ECC)

Based on plug and play technology, the ECC plugs into an expansion slot on the circuit monitor providingdirect connection to the Ethernet network using either UTP or fiber cabling. An RS485 MODBUS masterport on the ECC supports a daisy-chain of up to 31 additional devices without a repeater, allowing theCM4000 with ECC to act as an Ethernet gateway for the devices. The ECC supports MODBUS and TCP/IPprotocol. Embedded HTML pages allow for easy device setup and supply real-time power systeminformation from the CM4000 circuit monitor through a standard web browser. Similar information can alsobe viewed for devices daisy-chained to the ECC's onboard RS485 port.

AL ARM INFORMATION

The PMM/RPMM are equipped with one dry contact alarm which is activated when a metered valueexceeds a preset parameter, in the event of transformer over-temperature, TVSS failure, or activation ofthe EPO (Emergency Power Off) trip. An audible alarm will also sound in the event the dry contact alarmis activated. To obtain more detailed status of any monitored parameter, it is necessary to interface with thecommunications port of the PMM/RPMM monitor allowing alarms to be annunciated via software systems.

Standard alarms include:• One dry contact signaling general alarm conditions• Audible alarm• LED signal on MCM meter
