Energy & Demand Submeter with Data Logging & Wifi

​

The EPM 7100 is a powerful tool that allows customers to monitor and manage their energy usage within factories, businesses and across campuses. The EPM 7100 is a multifunction meter that features ANSI C12.20 (0.2% class) accuracy and RS485, RJ45 Ethernet or IEEE 802.11 WiFi communication connections, making the meter easy to deploy in modern and older communications systems. The extensive data logging and alarm recording capabilities of the EPM 7100 enable advanced analysis and predictive maintenance of the power system. The units use standard 5 or 1 amp CTs (either split or donut), surface mount to any wall and are easily programmed in minutes.

MONITORING & METERING  

​

Traceable Watt-Hour Test Pulse for Accuracy Certification
To be certified for revenue metering, power providers and utility companies need to know that the billing energy meter will perform to its stated accuracy. To verify the meter's performance and calibration, power providers use field test standards to ensure that the unit's energy measurements are correct. Since the EPM 7100 submeters are traceable revenue meters, they contain a utility grade test pulse allowing power providers to verify and confirm that the meters are performing to their rated accuracy. This is an essential feature required in all billing grade meters.

Utility Peak Demand Metering
EPM 7100 submeters provide user-configured Block Window or Rolling Window Demand. This allows you to set up a particular utility demand profile. Block Window Demand is demand used over a fixed user-configured demand period (usually 5, 15 or 30 minutes). Rolling Window Demand is a fixed window demand that moves for a user specified sub-interval period. An example is a 15 minute demand using 3 subintervals, providing a new demand reading every 5 minutes based on the last 15 minutes. Readings for kW, kVAR, kVA and PF are calculated using utility demand structures. Other parameters offer max and min capability over the user-selectable averaging period. Voltage provides a non-rolling instantaneous max and min reading, displaying the highest surge and lowest sag seen by the meter.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

COMMUNICATIONS  

​

 Standard Modbus RS485 Communication
Standard communication includes an RS485 output speaking Modbus protocol. This allows the unit to be connected to any serial RS485 bus using the Modbus interface. The unit communicates easily with most building automation or other software systems. Baud rates are up to 57.6K baud to provide fast update times.

WiFi or LAN-Based Ethernet
The unit offers two Ethernet options — either an RJ45 or WiFi connection. The WiFi option allows the EPM 7100 submeter to be used on standard WiFi base stations.

IrDA Port
Use an IrDA-equipped laptop PC to program and read the EPM 7100 submeter.

KYZ Pulse
For applications in which a pulse is needed, the unit also provides a KYZ output which pulses proportional to the amount of energy consumed. This feature is used for pulse counting applications or for building management systems where serial or Ethernet protocol is not available.

EPM 7100 ADVANCED LOGGING FEATURES 

 

Extensive Data Logging Capability
The EPM 7100 submeter has 2 Megabytes of Flash memory that give it extensive data logging capability. The EPM 7100 offers three historical logs, a limits (alarm) log and a system events log. The unit has a real-time clock that allows for time-stamping of all the data in the instrument when log events are created.

Historical Logs
Each of the three historical logs can be programmed with unique parameters consisting of any measured reading. Up to 64 parameters can be recorded per log.

Limits (Alarm) Log
The limits log provides magnitude and duration of an event. 2,048 events are available; the log provides time-stamp and alarm value.

System Events (Anti-Tampering) Log
To protect critical billing information, the meter records and logs the following with a time stamp:
 

• Demand/energy/log resets

• Password requests

• System startup

• Log reads

• Changes to meter's programmable settings

 

ENERVISTA SOFTWARE

​

EnerVista Launchpad
EnerVista Launchpad is a powerful software package that provides users a platform to access all of the setup and support tools needed for configuring and maintaining GE Multilin products.

EnerVista Launchpad allows configuration of devices in real-time by communicating using RS232, RS485, Ethernet or modem connections. Using Launchpad as the single interface to the setup and analysis software makes it easy to enter set points, read metered values, monitor status and evaluate power quality.

Included in EnerVista Launchpad is a document archiving and management system that ensures critical documentation is up-to-date and available when needed by automatically checking for and downloading new versions of manuals, applications notes, specifications and service bulletins.

EnerVista Integrator
EnerVista Integrator is a toolkit that allows seamless integration of GE Multilin devices into new or existing automation systems by sending GE device data to HMI, DCS and SCADA systems. Included in EnerVista Integrator is:
 

• OPC/DDE Server

• GE Multilin Drivers
