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.

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 4wire 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:

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.

Current 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.

Digital Input
The AC/DC digital input are independent (no common pin) and can be wired without polarity care.
Digital Output
The PhotoMOS have behaviour identical to a mechanical contact which closes. Therefore, there are not
problems with the polarity.
Serial Port
The instrument communicates via a asynchronous isolated serial interface in the standard RS485 Half-duplex
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 the shield to COM terminal.

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 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.
Pressing at the same Up and Down keys to return to default from the actual page.
Enter key
The Enter key when pressed in Measures, Graphics, Info Device and Setup pages 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 set value.
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.

Fig.1: Sag parameters Fig.2: Sag Explanation
A sag is defined as an under voltage condition that persists for more than one period of base frequency. A
shorter under voltage condition is called a dip (see Fig. 2). The occurrence of sag could announce an
impending loss of power.
To set the sag register the voltage must be under the Threshold value for a minimum time defined in Time.
