Energy Information System

with Network Technology

New functions

■

Several applications, which may even run

on different PCs, can all access one EMIS

®

1500 instrument online simultaneously.

■

One application can access several EMIS

®

1500 instruments online simultaneously.

■

Instrument data (stemming from EMA, EMF,

EML and EMR instruments) have been

assig-ned to data points (DPs).

■

All DPs can be registered as channels. In the

channel module they can then be managed,

displayed and analysed together with the

other registered channels.

■

Upper and lower alarm limits can be set for

all data points (at the EMIS

®

_{1500 level).}

■

Alarms can be routed individually (and in

groups) to the following alarm paths:

- Contacts on EMIS

®

_{1500 or EMD 1101}

instruments

- Network printers

- SMS and faxmessages

- E-mail

- Alarm protocol

■

Historical data can be presented in a

dia-gram for as many days as desired (up to one

year being practical).

■

Several internal and external time pulses can

be programmed. They are available in the

entire system.

The EMG 1500-PN Gateway forms an

interface between the Ethernet and the

FRAKO Starkstrombus

®

_.

It is possible to install a maximum of

eight Gateways per EMIS

Ethernet system.

Gateways can also be linked up via a

company's internal network.

Other standard bus systems such as

Modbus can also be connected.

Intensive ongoing development of the

proven FRAKO Energy Management

System has resulted in the EMIS

₁₅₀₀

Central Unit, representing

state-of-the-art data collector technology.

In addition to the widespread Ethernet

technology with TCP/IP, the Linux

ope-rating system is used within EMIS

System Timer EMT 1101

Module for timing control

■Timing control for electrical installations such as com-pressors and HVAC systems: switching these on and off via volt-free contacts reduces energy costs.

■Central control of loads means that no local timing control is necessary. This also enables switching times to be changed quickly and simply at a PC, for example when the daily working time is extended.

■Timing control of circulation pumps to reduce heating costs

■Automatic ventilation of rooms

■Switching of solenoid valves in the compressed air main to reduce leakage losses

■Timed adjustments to alarm set points to identify leaks during the night or at weekends

■Up to 100 switching channels can be combined into several switching groups

■300 switching operations

■150 daily programs

■Weekly program

■Exceptions table (caters for up to 365 exceptional days in the year, such as those with longer working hours)

Repeater EMB 1101

Signal conditioning and distribution

■Necessary for lines with a length of over 1000 m and for bus systems where more than 32 instruments are served by one line

■Installing the repeater improves the reliability of the bus system, especially under difficult operating conditions that cause interference.

■Radial wiring system; up to four lines, each connected to a maximum of 32 instruments, can be wired to one repeater.

■Cascading repeaters enables bus lengths of up to 15 km to be installed.

■The repeater can electrically isolate sections of the bus system in order to prevent stray currents flowing in the FRAKO Starkstrombus®_.

Communications Processor

EMP 1100

Module for data interchange between the FRAKO Stark-strombus®_{and PLCs, PCs, centralized instrumentation and}

control and building automation or similar systems

Overview of a data block with the current parameters for an energy management instrument

Ethernet Interface

EM-COM Server

A convenient solution for serial interfaces: direct connection to network

■As an RS232 interface is generally specified for data interchange over short distances, it becomes more complicated when longer lines are involved. In addition to widely used data interchange options such as modems or optical fibre converters, it is also possible to use the network cable.

■Instruments that are not accessible via a fieldbus (2-wire) are linked to the system by means of the COM server if a network connection is available.

■Instruments installed in other properties can be con-nected to the Energy Management System via the internal network.

Energy Management Components

■Data from any instrument of the FRAKO Energy Mana-gement System can be transmitted to external systems

■Serial interface A (standardized): 3964R protocol, RK512 interpreter

■Serial interface B: access via PC

■Programming and parameterizing software included in scope of supply

■Three LEDs indicate operation, access to the FRAKO Starkstrombus®_{and access to one of the serial interfaces.}

■Current data from up to 100 instruments of any type in the FRAKO Energy Management System are saved in a maximum of 100 data blocks. The cycle time for data polling is adjustable.

■Transmission rates up to 1.5 Mbit/s (adjustable with DIP switches)

■Distances up to 3300 m between two couplers possible

■Complete regeneration of the electrical and optical signals through active bit retiming

Voltage/Current/

Frequency Converter EM-UIF

Signal converters are used to convert and isolate a variety of measurement signals in electrical power and tele-communications systems. They are always indispensable whenever measurement readings need to be transmitted over relatively long distances and to various locations for display and processing. The signal converter is used in the FRAKO Energy Management System for the acquisition of operating data, converting a DC analogue input signal of 0 – 10 V / 2 – 10 V or 0 – 20 mA / 4 – 20 mA into an AC pulse frequency of 0 / 5 Hz. This enables meters with any type of output signal to be connected to the FRAKO Energy Management System for data acquisition and visualization purposes.

Temperature Transmitter

EM-PTF

The transmitter is used in the FRAKO Energy Management System for the acquisition of operating data. It has a pulse frequency output of 0 – 5 Hz over a temperature range of –40 °C to +120 °C. This enables temperatures to be moni-tored, measured and visualized with the FRAKO Energy Management System.

Temperature Probe

EM-PT 100

The EM-PT 100 resistance temperature detector is designed to operate with the EM-PTF temperature transmitter and the EMA 1101 mains monitoring unit for operating data acqui-sition in the FRAKO Energy Management System

■Temperature range –40 to +120 °C

■Accurate measurement with 4-wire lead configuration
