Description

The EMS (Electrical Measurement Supervisor) has advanced analysis functions that allow the measurement of the main electrical parameters: voltage, current, frequency, power factor, active and reactive power, active and reactive energy. The instrument allows the measurement and analysis in real time of electrical parameters, also verifying the quality of the energy thanks to THD measurement. Bidirectional metering of energy allows both production and consumption of energy to be monitored with a single device. All information monitored by the analyzer can be transmitted to remote locations through communication interfaces RS485, Ethernet with the support of numerous protocols including Modbus RTU, Modbus TCP/IP and Profibus DP. Interaction with the control and supervision systems is possible using inputs and outputs, all programmable. EMS reads and displays the energy values measured in other energy meters connected to the network. This is achieved thanks to digital inputs, which are able to acquire the impulses generated by the counters. In this case, EMS acts as a data concentrator. It not only collects information from the electricity meters but also from the water, gas meters or other. EMS allows a complete, in-depth analysis of the network quality thanks to the measurement of the harmonic distortion (20

order) of the voltage and current signals.

When the device is received, before beginning installation, check that it's O.K. And it has not suffered any damage during transport. When starting installation make sure that the operating voltage and mains voltage are compatible with the device instructions. The device power supply must not be earthed. Maintenance and/or repair must be carried out only by qualified and authorized personnel. If there is ever the suspicious that, that there is a lack of safety, during operation, the device must be disconnected and cautions taken against accidental use.

Operation is no longer safe when:

- The instrument doesn't work.

- The measured value are obviously wrong or unreasonable.

- There is visible damage.

- After serious damage incurred during transport.

- After a storage under unfavourable conditions.

During normal operation of the devices, hazardous voltages at its terminals and in particular on the terminals of voltage and current transformers connected and on the terminals of the digital input and outputs. The secondary circuits of the voltage and current transformers are capable of generating hazardous voltages and currents when their primary circuit is powered. Follow the standard safety precautions when performing any installation or service (such as making sure that the power supply is disconnected, disconnecting the fuses of the transformer voltages, short-circuiting the secondary of current transformers etc.). Don’t use the instrument when failure may cause injury or death, or generate sufficient energy to cause a fire.

Auxiliary power supply

The instrument can be supplied with a voltage independent by the monitoring line. In this case, the instrument continues to operate independently by the voltage present on the lines under control. Alternatively, only for 90÷250Vca/cc version, it is possible to take the power from the network under test, using

the phase and neutral for a 4-wire network, phase to phase in a 3-wire system without neutral or from a VT in a MT application. In this case when the voltage of the monitored line falls below the minimum limit, the instrument turns off. The instrument can be supplied in two different configurations of power supply:

Standard Version

90÷250 Vac/dc

Option Version

20÷60 Vac/dc

Voltage Inputs

4 terminals are available for direct connection to 3 phase network with neutral. In case of a 3 phase balanced

system without neutral, or non distributed neutral to leave terminal N free.

3 inputs, range 30 ÷ 400Vac phase to neutral - 52 to 693Vac phase to phase (see Technical Features table for

details); over these values must used the external voltage transformers.

Frequency range: 50/60Hz.

Permanent overvoltage allowed: 480Vac phase to neutral - 830VAC phase-phase.

Overvoltage category: II (permanent installations).

Pollution degree: 2 (normally non-conductive, conductive condensation temporary). Input resistance: > 1.8MΩ. Load (Burden) for each voltage input: 0.09VA. Note: To detect the frequency of the network the terminal VL1 must be always connected.

Current Inputs

Current measurements can be performed by connecting the terminals of Current inputs. All current inputs are isolated by current transformers with different ranges depending on the model of the instrument. They can be interfaced directly to the line to be monitored or to be connected to the output of external CT with higher range. The connections to the lines to be monitored are described in chapter “Wiring diagrams”. With neutral current input option installed, the instrument allows the direct measurement of neutral current in the same way described for the line inputs.

NOTE: it is essential to observe the correct phase sequence, not invert the connections between the phases of the current inputs and voltage (i.e. the CT placed on L1 phase must absolutely match at I1 Current and VL1 voltage). Do not invert the terminals S1 and S2 of the CT because the measurement of power factors, and the powers would no longer be trusted.

Version 5A

Three-phase current inputs isolated by 3 internal current transformers. Nominal current range 50mA÷5A; over these values must be used the external current transformers. Load (Burden) for each current input: 0.0009VAmax.

Version 1A

Three-phase current inputs isolated by 3 internal current transformers. Nominal current range 10mA÷1A; over these values must be used the external current transformers. Load (Burden) for each current input: 0.0009VAmax.

Version TTA50

Three-phase current inputs isolated by 3 external current transformer (openable). Nominal current range 500mA÷50A.

Version TTA100

Three-phase current inputs isolated by 3 external current transformer (openable). Nominal current range 1A÷100A.

Neutral Current: the nominal current range depends by the version.

In case of connection in a 3 phase network (without

neutral or with neutral not distributed) don’t connect the

N terminal.

WARNING: If the instrument has the TTA on the current inputs, DON’T connect the S2 terminals to the earth.

This connection with only 2 CT allows to measure accurately the three-phase currents.

WARNING: If the instrument has the TTA on the current inputs, DON’T connect the S2 terminals to the earth.

This connection can be used with distributed and equal loads. It is possible to measure the current on one phase (using only one CT). The unmonitored phase currents are mathematically calculated. The measurement of neutral current is optional.

WARNING: If the instrument has the TTA on the current inputs, DON’T connect the S2 terminals to the earth.

In presence of multiple balanced loads in a three-phase network, the instrument calculates the electrical parameters checking a single phase current for each load, allowing to limit the number of CT used.

WARNING: If the instrument has the TTA on the current inputs, DON’T connect the S2 terminals to the earth.

Serial ports (option)

Depending on the version, the instrument can be equipped with one or two isolated half duplex RS485 serial interface. Two options are available: 1 serial port RS485 2 serial ports RS485 With these options the instrument can communicate with the external with the Modbus protocol. The two ports are independent and they can perform the same operations. The presence of the serial port RS485 allows the software update.

COM1 A1: +data B1: -data C1: common

COM2 A2: +data B2: -data

C2: common The instrument communicates via a asynchronous isolated serial interface in the standard RS485 Halfduplex that allows a connection in a network up to 247 nodes. This allows to implement a communication network between different instruments and a master unit (data concentrator) for a detailed control of an electrical installation. The maximum length of the line depends on variables such as the transmission rate and characteristics of the cables used. It’s recommend to use a shielded twisted pair cable with low attenuation, with a minimum section of 0.36mm2 (22AWG) and capacity of less than 60pF / m.

The maximum length is about 1200m. For longer distances it’s need to use signal amplifiers (repeaters).

High networking length and/or where environments are electrically "noisy", it requires the use of two termination resistors (at the beginning and end of the line) of 100 -120Ω. The use of repeaters is also necessary in the case of networks with more than 32 nodes. At each repeater can be connected 32 units. Please note that complex networks with large number of nodes cause a slower speed of response by

the instruments. Connection type: half-duplex (2 wires + common). Isolation: opto-couples (3750 Vrms min.). In the figure is showed a connection with a not shielded cable. In the shielded cable connection it’s necessary to connect th e shield to COM terminal.

Profibus port (option)

Profibus-DP is a multi-master systems. In the networks it’s possible to have up to 126 devices on the same bus. In profibus-DP networks, the interchange of data between peripheral modules and the master is made automatically by the profibus controller, which ‘virtualise’ the data exchange memory of the DP devices in the memory of the master. In the following picture the pin-out of the Profibus-DP port:

The profibus interface detects automatically the baud rate of the network; the baud rate available are:

9.6 Kbit/s

19.2 Kbit/s

45.45 Kbit/s

93.75 Kbit/s

187.5 Kbit/s

500 Kbit/s

It’s possible to request to the manufacturer application examples, GSD files and protocol manual (IM157).

The 3 yellow led on the back have the following meanings:

- instrument not parameterized: the 3 led turn on continuously in the sequence PAR - ExB - ExA

- instrument parameterized: led PAR turned on

Function keys

Directional keys (Up/Down/Left/Right)

The directional keys are used to change the pages in Measures, Graphics, Info Device e Setup. In the next chapters the maps show how to move between pages. At the same time the directional keys allow to move and select items inside the Menu. The Up and Down keys are used to increases and decrease or simply to change the set values in the Setup pages. Pressing at the same time the Up and the Down keys to return from the actual to default page. Pressing at the same time the Left and the Right keys it’s possible to define the default page. The title page will change the colour and the “home icon” will appear near the text to confirm the new default.

Enter key

When the Enter key is pressed in Measures, Graphics, Info Device and Setup pages it allows to enter in the Menu and it is used to confirm the item selected. In the Setup it allows to modify and to confirm the new value. In the Measures and Graphics pages, when the key is released after a long press (more than 4 seconds) the map of the pages is showed on the display; in the User Pages, instead, it allows to escape by opening the menu.

Esc key

This key is used:

- to skip without to confirm the modify

- when a page of Measures, Graphics, Info Device and Setup is displayed, pressing Esc the display will show

all levels path to reach the last page opened by using the menu from the turning on of the instrument.

Frontal led

On the frontal panel there are two led that blink proportionally to the energy read. For default the right red led shows the “System Active Energy IN” and the left red led shows the “System Reactive Energy IN”. In the setup is possible to modify the default set with the following parameters:

- System Active Energy IN

- System Active Energy OUT

- System Reactive Energy IN

- System Reactive Energy OUT

- System Apparent Energy

The weight of the pulses of these led is 0.1 Wh, VArh, VAh for each pulse. This value is not modifiable.

First configuration

At the first switch on and after every Global Reset the instrument allows to set the main parameters for a correct used:

1) Language selection

2) Wiring (see Connections paragraph and Wiring/Conventions table)

3) CT ratio (see Transform Ratio table)

4) CT-N ratio (only if the neutral CT is mounted on the instrument, see Transform Ratio table)

5) VT ratio (see Transform Ratio table)

6) Hour

Energies and Counters

The EMS-96 has 4, 8 or 16 timebands (depending of the option) to differentiate the power consumption. You can schedule the exchange of the timebands using manual (Modbus command), from DI (digital inputs) or Preset (Setup  Timeband  Mode  Preset). With from DI it’s necessary to set the use of digital inputs for this purpose (Setup  I/O  DI 1, 2, 3, 4  Mode  Change TB). With Preset it is necessary to define a Daily plan in which you set the time of transition (maximum 16) from one to the next timeband. In the setting of Period plan (Setup  Timeband  Preset  Daily/Period Plan) it will be selected the month and the day of the start and the end, and it will be necessary to link each Daily Plan to one or more days of the week. At the end of settings the Period Plan will be enabled. Any holidays will be set in the menu Holidays (Settings  Timeband  Preset  Holidays).

User pages

The EMS-96 provides the user with six pages configurable. You can choose the type of page (instantaneous values, average values, energies, graphics and setpoint) and its composition (up to 6 measurements for page). If you choose the type setpoint, the text associated to each setpoint can be changed in Setup  Setpoint  Texts in order to have a clearer association between the alarm and its visualization. In the user pages it’s possible to change the title (Setup  User pages  Titles) so to have a clear view of the contents. For example, in the case of systems composed of several independent phases it’s possible to group voltage, current and power of the L1 phase, in a single page with a title that can highlight the belonging to the same user.

Low threshold

± 9999

Minimum value associated to the low threshold.

Low threshold unit

See below

See below underlined

* These settings are used for the optional analog outputs from AO-1 to AO-4. Example: to associate the L1 phase voltage to the analog output it is necessary select instantaneous for the item Measure group and the acronym V1 for the item Measure associated. If the maximum value is set to 300V and 100V to the minimum, with the scale of 0÷20mA, it will have that with 200V as measured voltage, the output will be 10 mA.

Only for the power factor, cos and tan is used a different logic (see the following example).

Selecting the cos or the power factor as a measure to associate to the analog output, the intermediate output value (10 or 12 mA) is set to cos =1 (and coinciding with cos =-1). The value of the output signal will trend to increase when the positive values of cos decrease from 1 to 0 while for the negative values, it will decrease when the value trend to 0.

Example: Setting +800 and -800 as maximum and minimum values when cos =0.9 the value will be 15 mA, while when the cos =-0.9 it will be 5 mA.

In the case of selection of tan the intermediate output value (10 or 12 mA) is set to tan =0 and the output signal will be directly proportional to the variation of the measure.

EMS-96 Instruction Manual IM1200-U v1.6 Pag. 38 / 48

Setpoint

The EMS-96 provides to the user, functionality that perform multiple actions when a measure exceeds the set limits, in the way to take automatic corrective actions. The setpoint (32 available) are made by 3 main areas:

- parameter to be controlled with its limits;

- logic to be used;

- action to be taken.

To use the setpoints correctly, it’s necessary to follow these points:

- Select the Source of the measure to control

between internal measures and external (COM in Master mode).

- Select the Group and the Item (the measure

inside the group).

- Define what are the limits that the measure

must not exceed (High threshold + High

threshold unit and Low threshold + Low threshold unit) and the time spent out of the limits themselves (Over debounce, Entry debounce and Hysteresis) in order to avoid

continuous changes the state of alarm when the read value is near the thresholds set.

- If the limits are exceeded and if it’s

necessary to control more parameters simultaneously and to have a single action, there is the possibility to link more setpoints using the two main logical operations (AND and OR). To use this feature you must set only one setpoint as "primary" with the following setup:

- limits;

- debounce (Over / Entry);

- logic (Over / Entry);

- operands (secondary setpoints to be included in the logic);

- action (Over / Entry);

and others setpoint as "secondary" in which only the limits and the debounces will be set.

- Set the action or the actions to be taken (Action over / Action entry) in the case of pass / return of the limits previously set,

between the following items:

- save the event;

- change the status of one or more digital outputs;

- increase the counter of exceeding limits;

- start the timer whenever the measure exceeds the limits.

- After setting the parameters of the set point, and only at the end, it’s necessary to select yes for the voice Enable.
