WARNING!
•Carefully read the manual before the installation or use.
•This device is to be installed by qualified personnel, complying to current standards, to avoid damages.
•Before any maintenance operation on the device, remove supply inputs.
•The manufacturer cannot be held responsible for electrical safety in case of improper use of the equipment.
•Products illustrated herein are subject to alteration and changes without

Introduction
The EMA-D6 is a Network Analyzer for displaying all the relevant system parameters in low and medium voltage power distribution. It is capable of single-phase,
two-phase or three-phase measurement and can be used in two-wire, three-wire, four-wire, TN, TT and IT systems.
Thanks to its large measured voltage range, the EMA-D6 with multi-range power supply can be connected in any low and medium voltage system up to a rated
system voltage of 690 VAC.
Higher voltages can be measured using voltage transformers. For measuring current, either x/1 A or x/5 A current transformer can be used or Rogowski coil
(optional), TT/TTA sensors (optional) or 333 mV (optional).
The combination of four function keys with the multi-language plaintext displays makes intuitive user prompting possible. The graphic color LCD offers user-friendly
interface.
The RS-485 or Ethernet interface or an optionally available interface module can be used for communication. In addition, the EMA-D6 has a multifunctional digital
output using an alarm. The analyzer can accept up to 4 digital inputs. The parameters can be set either direct on the device or via the communications interface.
Password protection is integrated via the front of the device to guard against unauthorized access.

- The title of the page can be freely programmed by the user.
- Like all other pages, it’s possible to set the analyzer to return automatically to the user page after a time has elapsed.
- To define the user page, see the dedicated menu USER PAGE chapter.
Time and date
- The EMA-D6 manages the date and time, that is used for storage of events, for measurements log and for time-related functionalities.
- The EMA-D6 is equipped with RTC (real-time clock), then the time and date are kept updated even without auxiliary power supply, for a maximum of about 1 week.
- Setting date and time is mandatory in order to use the time-related functionalities on the device (maximum, minimum, historical).
Password access
- The password is used to enable or lock the access to:
•setting menu
•display viewing
•keys
•communication
- For new devices, the password management is disabled and the access is free. If instead the password have been enabled, then to get access or change any
configuration of the device, it’s mandatory to enter the password.
- The password is valid as soon as the user remains in the Configuration section or others lock sections and for a max setting minutes (see the dedicated menu
PASSWORD chapter).
- After quitting the Configuration section or others lock sections, it’s needed to enter again the password.
Additional resources
- The options provide additional resources that can be used through a dedicated setup menus.

Communication channels
- The EMA-D6 supports a maximum of 2 RS-485 communication channels (COM1 and COM2) and a maximum of 1 Ethernet port.
- The communication channels are completely independent and can communicates at the same time.
Daisy-chaining devices to the network analyzer
The RS-485 slave port allows the network analyzer to be connected in a daisy chain with up to 32, 2-wire devices. See Figure below.
Setpoint thresholds
- The setpoint thresholds are internal variables whose status depends on the out of limits of one particular measurement set by user among all those measured
(example: active power higher than 40 kW).
- For each setpoint, there are 2 thresholds (upper and lower). The upper threshold must always be set toa value higher than the lower threshold.
- For every setpoint is possible to set a delay when alarms is triggered on and off.
- When specific conditions are met, alarms is turned on or off. Triggering of alarms can be registered in the devices notifications log, in the events section, increasing
timer. In addition to that, they can be set up to control digital outputs of the device.
- There are two types of setpoints available on EMA-D6: simple setpoint and “complex”condition to a setpoint using Boolean logic variables (AND, OR).
- For setpoint thresholds programming and definition refer to setup menu SETPOINT chapter.
For more information on how the meter handles the setpoint-driven alarms, refer to the figure below.
Data logger function
- The data logger allows to store at regular interval up to 14 variables chosen freely among the multimer measures.
- Every record is marked with a timestamp taken from the internal real-time clock. The minimum sampling period (distance between two records) is of 1 second.
- Considering the amount of memory, the number of variables to be stored and sampling period, the unit indicates the time that must elapse before the memory is
completely filled.
- The recording can be continuous (driven only by regular time intervals) or conditional (between a specified date/time range), driven only by the status of the internal
variables (setpoint) or digital input status.
- When the memory is full, the user can choose to stop the recording (End Memory mode) or to continue overwriting the oldest records (FIFO mode).
- The display page dedicated to the data logger info (MENU - INFO - LOG SUMMARY) shows all the fundamental information: number of records, sampling,
available free memory, residual time before the memory if filled (when working in End Memory mode).

1- Enable or disable the data logger function. Every record is marked with a timestamp taken from the real-time clock.
ALWAYS - The data logger allows to store at regular intervals up to 14 variables. The recording is continuous (driven only by regular time intervals).
BETWEEN DATE - The recording allows to store at regular intervals only between a specified date range.
BETWEEN HOUR - The recording allows to store at regular intervals only in the specified time interval.
BETWEEN DATE AND HOUR - The recording allows to store at regular intervals between a specified date range and time interval.
TRIGGER - The recording allows to store at regular intervals driven only by the status of the internal variables (setpoint) or digital input status.
2- Time interval between a data reading and the next one.
3- When the memory is full, you can choose to stop the recording (End Memory mode) or to continue overwriting the oldest records (FIFO mode).
4, 5, 6, 7 - Set the variables (driven by date range or/and time interval) that control the starting of the recording.

12 - The recording can be disabled for a specific day of the week.
13 - Set the internal variables (setpoint) or digital input status to allows the recording.
14 - Define the number of digital input which controls the starting/ending of the recording.
15 - Define which setpoint controls the starting/ending of the recording.
16 - The data logger allows to store at regular interval up to 14 variables. To configure the data logger, it’s necessary to select the source variables (network
analyzer’s measures or from external devices).
17 - The data logger allows to store at regular interval up to 14 variables. To configure the data logger, it’s necessary to select the group variables.
