SETTING THE DEVICE VIA SOFTWARE FACILE QA-POWER-M
It is possible to use the program without connecting to the module,
in this mode you can SAVE the configuration on your PC, which can
then be sent to the QA-POWER-M at a later time.
SERIAL PORTS AVAILABLE:
Check the available COM ports, press the UPDATE button. Your PC
will assign a virtual COM connection with the QA-POWER-M. Press
START CONNECTION WITH THE DEVICE. It will confirm you the
connection was successful with the module. If the connection does
not happen, please check the RS485 serial connection (A +, B-), the
position of the dip-switches (switching off and on the device) and
the COM generated automatically by the device. After connecting,
you can proceed with the configuration of the device.
CURRENT RATIO, PULSE MANAGEMENT, FILTERS & CUT-OFF
SETTINGS:
This step on the FACILE QA-POWER-M software allow to to define the
Current Ratio in case of external CT presence, otherwise you can
measure direct current AC/DC up to 10 A.
The Pulse weight of the digital output can be setted by the WEIGHT
IMPULSE FOR ENERGY CALC (Wh).
RMS FILTER and AVERAGE FILTER COEFFICIENT are two different types
of filters that allow you to introduce a delay of the answer in order
to have more stabilty of the reading.
CUT OFF settings: you can set the cut off values for VOLTAGE,
CURRENT and POWER measurement. Under these value setted the
measurement will be Zero.
SETTING THE DEVICE VIA SOFTWARE FACILE QA-POWER-M
The programming of the module QA-POWER-M may be performed in two different ways:
· via the interface program free FACILE QA-POWER-M through the microUSB port on the module or via RS485 connection;
· via the RS485 serial connection (from terminal or T-Bus).
The QA-POWER-M has two microprocessors, you can configure the module by connecting it to the USB port of your PC without

ANALOG OUTPUT: the first drop-down menu in the upper left allow you
to associate the analog output to a single selectable Vrms, Irms, Active
Power, Reactive Power, Apparent Power, Cosφ, Frequency.The mode
of the analog output is VOLTAGE or CURRENT. The QA-POWER-M has the
ability to scale the input and output as required, then select the
measurement range of input (INPUT BEGIN SCALE and INPUT END SCALE)
to assign to the analog output signal (OUTPUT BEGIN SCALE and
OUTPUT END SCALE ). Depending on the choices made in the two menu
will change the units of measurement values in the input and output. If
you select the MANUAL CONTROL VIA MODBUS, you can manage the
module as if it were an AO (Analog Output), thus freeing the analog
output from the input selected. The analog output will be handled via
RS485 Modbus RTU (see register map).
DIGITAL OUTPUT:the digital output default set is NOT ACTIVE. If you
want to ACTIVE the digital output please set it on the right window.
ALLARM / FAIL ANALOG OUTPUT: it is possible to use the analog output
to control any supervening anomaly Hardware HW FAIL, FAIL RTC Real
Time Clock anomaly that stores the date and time, FAIL EEPROM for the
anomaly on the microprocessor, FAIL LOG if an anomaly occurred during
data acquisition, UNDER RANGE scale of measurement set, OVER RANGE
scale of measurement set. It is possible to select multiple items in the
menu. In case of alarm the analog output will go to 21 mA or 10.5 V
depending on the selection made in the previous window.
ALARM WINDOW: you can activate the ALARM functionality (in the gray
box), on the digital output or on the analog output, or both
simultaneously. In this window you can manage HOW andWHEN activate
the alarm by selecting the options from the dropdown menu: MORE
THAN A THRESHOLD, LESS THAN A THRESHOLD, NOT BETWEEN TWO
THRESHOLD, BETWEEN TWO THRESHOLD. We therefore have the
possibility to insert the values of THRESHOLD and the value of
HYSTERESIS. In the case where it is selected the value of a Higher
threshold when the signal falls below, the alarm switched off at the
threshold value minus the value of hysteresis. In the event that you have
chosen the value of a Minor threshold, when the value exceeds the
threshold plus the hysteresis value, the alarm is disactivated. In the case
where it is selected between two thresholds, the hysteresis is external.
In case you have selected Not included between two thresholds, the
hysteresis is internal.
ALARM / FAIL DIGITAL OUTPUT: it is possible to use the digital output
to control any supervening anomaly Hardware HW FAIL, FAIL RTC Real
Time Clock anomaly that stores the date and time, FAIL EEPROM for the
anomaly on the microprocessor, FAIL LOG if an anomaly occurred during
data acquisition, UNDER RANGE scale of measurement set, OVER RANGE
scale of measurement set. It is possible to select multiple items in the
menu. By clicking on the "ENABLE ENERGY PULSE" is enabled the pulse.
STATE DIGITAL ALARM / FAIL allows you to define the status of contact
in case of alarm (NOT ACTIVE or ACTIVE).
FAIL MESSAGE / ANOMALY:
FAIL HW: problems in the measurement chain (electrical
connections, microprocessor that manages the
measurement, sensor disconnected or faulty).
FAIL LOG: problem on recording data (without the
availability of stick usb memory stick usb not recognized).
FAIL RTC: problem on backup battery (dead or defective).
FAIL EEPROM: problem microprocessor configuration (not
calibrated module, takes no configuration).
MODBUS COMUNICATION:
This is the last window of the device configuration. The left
column contains the parameters to be set for the
communication speed BAUDRATE (from 1200 to 115200),
the PARITY (None, Odd, Even), the STOP BIT (1 or 2), the
Modbus address to be assigned to the device . You do not
need to configure these parameters for the use of the
module with digital / analog output. It is possible to use
the module with RS485 serial output with Modbus output
analog and digital simultaneously.
LOGGING :
On the right side of the window you can enable the feature
LOG for the acquisition of data on usb pendrive. You can
name the log file by associating the extension .Xls, .Xlsx,
.Csv, .Txt, .Dat, .Logs. The default file is in text format. The
minimum sampling time is 1 second, the maximum is about
18 hours.

The QA-POWER-M provides, on a local memory type PEN DRIVE USB (USB KEY) connected to the module via the microusb port, a series of information
concerning the operation of the module, alarm status, type of input, the output type, the reading of the measured data, the measure of the output value
from the module.
For each row correspond to a precise time reference. The module is equipped with an RTC RealTime Clock powered by a backup battery that lets you record
data with YEAR / MONTH / DAY / HOUR-MIN-SEC.
The first number listed is the SERIAL NUMBER of the module, which allows it to be uniquely identified.
The second column give you information about: DATE (YEAR / MONTH / DAY / HOUR-MIN-SEC).
It is then reported the STATUS ID (Registry STATE) in binary mode to 16 bit. The binary number corresponds to the Modbus register 40005 that represents
the state of the machine (Status: bit 0 = fail global, bit 1 = alarm, bit 2 = over range, bit 3 = under range, bit 4= ?, bit 5=dout status, bit 6 = fail hw, bit 7=fail
log, bit 8=fail rtc, bit 9=fail eeprom).
The following coloumns are Vpk, Ipk, Vrms, Irms, Active Power (P), Reactive Power (Q), Apparent Power (S), Cosφ, Frequency, Energy Total,
Energy +, Energy -, Output Value, Output type ( bit 0=Voltage/Current, bit 1-4=input Vrms, Irms, Active Power, Reactive Power, Apparent Power,
Cosφ, Frequency, bit 5 = fail ur, bit 6 = fail or, bit 7 = fail hw, bit 8 = fail log, bit 9 = fail rtc, bit 10 = fail eeprom, bit 11 = fail alarm, bit 12-13 = 1 threshold
over/1 threshold min/2 thresholds external/2 threshold internal, bit 14= Manual mode), this value follows the setting made via FACILE or via RS485.
HOW TO IMPORT LOG DATA FROM EXCEL VERSION BEFORE 2003:
it‘s possible to import the data stored on the USB Memory Stick at any time (even if the log is not finished). Once you open the file with Excel (or Open
Office), you will have to act on the functionality of the program for wrapping the data as described above. To do this, you can perform the following steps:
select the first column, go to the option data, click on TEXT COLUMN, then choose the option that provides for the separation of the data by tabs or commas,
the next step endorse the option POINT and COMMA.
LIVE DATA USING FACILE QA-POWER-M:
once confirmed the configuration, the FACILE QA-POWER-M allow you to see the
data reading by the device directly. Please remind that you have to supply the device
by external power supply .
