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 r(20th order) of the voltage and current signals.

To enable one or more options it’s necessary to input a code (Enable option item) in the instrument setup. If

the options are requested at the moment of the order the code is already loaded and showed on the

instrument report.

After the installation, to enable one or more options it is necessary to request the code to the seller, sending

the serial number. The seller will deliver the new code to load in the instrument setup.

INSTALLATION

Warning for the user

Read carefully the instructions/indications contained in this manual before installing and using the instrument.

The instrument described in this manual is intended for use by properly trained staff only.

Safety

This device has been manufactured and tested in compliance with EN 61010-2 standards. In order to

maintain these conditions and to ensure safe operation, the person must comply with the indications and

markings contained in the manual.

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 values 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 voltage, short-circuiting the

secondary of current transformer etc.).

Do not use the instrument in situations where failure may cause injury or death, or generate sufficient energy

to cause a fire.

The instrument is equipped with a fuse on the power supply type: 5x20mm 1A 250V time lag.

CONNECTIONS

Auxiliary power supply

The instrument has an auxiliary supply for the logic and interfaces. This is useful to maintain active the logic

also in absence of power of monitored lines.

In alternative, 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

the instrument will be switched off in absence of power of monitored lines.

The instrument can be supplied in two different configurations of power supply:

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: 0.0009VA max.

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: 0.0009VA max.

Neutral Current: the nominal current range according with CT version (5A or 1A).
