DPD Manager
Windows Desktop App
for DPD setup via NFC communication
User Manual

2
DPD is a three-phase multifunction configurable monitoring relay with NFC
communication suitable for both Delta and Star mains.
It protects loads from wrong phase sequence, neutral and phase loss,
additionally voltage, frequency and asymmetry setpoints can be set and provide
output signals.
DPD is delivered with a set of factory settings, among the two available ones,
which are the most commonly used.
If factory default parameters are not completely suitable, they can be modified
according to own requirements, by Windows PC, tablet or smartphone.
Windows and Mobile apps allow to select the required settings on screen, save
them for future use and send the new configuration to the DPD or DPDs to be
configured.
NFC communication can also be used, by means of the proper app, to download
the configuration from one DPD and to send the same configuration to other
DPDs.
About factory settings, see “DPD DEFAULT PARAMETERS” table on the last page.

DPD Manager Installation
System requirements:
•OS Windows 8 or higher
•FREE MEMORY: 200 MB for installation and use
NFC:
•The communication via ACR1252U NFC reader and writer requires driver installation
for correct operation.
Download the correct ACR1252U driver from one of the following links:
http://www.productselection.net/Download/UK/ACR1252_Winx86_32bit.zip
http://www.productselection.net/Download/UK/ACR1252_Winx64_64bit.zip
Select the 32-bit or 64-bit driver based on your system requirements.
Start the Setup file for installing the NFC reader driver.
App download:
Download the Windows Desktop App from Carlo Gavazzi web site:
http://gavazziautomation.com/images/PIM/OTHERSTUFF/Setup_DPD.exe
Launch the Setup file
Launch the DPD App from desktop or start menu.

5
Before proceeding with the specific action to do with the app, in the settings environment,
check for available updates, choose the language to use, the NFC reader/writer associated
with the PC and if to enable or disable the serial number confirmation popup.
The serial number confirmation popup feature is useful when more
than one device is sitting side by side to confirm which device is going
to be used. This applies in the following cases:
•apply a configuration to the target DPD,
•see alarms or outputs status and variable values in real time,
•load a configuration from another DPD,
•restore default settings,
•lock or unlock the DPD.
If the feature is enabled, the serial number that appears on the popup
must be compared with that of the target DPD and then confirmed to
proceed with the action or change the target DPD.
Otherwise, the chosen action will be immediately performed.

6
Create DPD Configurations
Select "Create new configuration" from the middle screen button or from "+ Configuration" in
the top left menu.

7
In the “General”page, enter name (max 64 characters) and description (max 500 characters)
of the configuration.
Select the line type:
•three-phase with neutral (3 PH + N),
•three-phase without neutral (3 PH).
Then, select the line nominal voltage within the range:
•3 PH: 208 to 480VAC (line to line)
•3 PH + N: 120 to 277VAC (line to neutral)
Set the inhibition time of the “Power ON delay” according to the mains instability time at the
start-up of the load, to avoid unnecessary interventions of the DPD.
The delay can be configured from 0 to 6s.
Press “Next” button on the bottom right to go to the next configuration page.
In the “Thresholds” page, up to 10 non-priority alarms can be configured.
Select one by one the alarms that are required to be set.

8
Each of the 10 non-priority alarms can be set as above.
Select among "Voltage", "Frequency" or "Asymmetry".
Select if the alarm is "Over" or "Under".
In case of asymmetry alarm, it is enough to set the percentage.
Set the setpoint values, based on the following ranges:
•3PH voltage: 177 to 552V,
•3PH + N voltage: 102 to 318V,
•Frequency: 45 to 440 Hz,
•Asymmetry: 0-30%.

9
Set the hysteresis value in the range:
•voltage and asymmetry, 1 to 5%,
•frequency, 0.1 to 5%.
Set the delay values in the range:
•delay ON alarm, 0 to 60s,
•alarm OFF delay, 0 to 600s.
The configured alarms show the type and value of the measurement.
When all alarms are set, press “Next” button on the bottom right to proceed.

10
In the “Alarm” page it is possible to enable or disable the phase loss, neutral loss, phase
sequence and measurements out of range priority alarms.
Considering phase loss alarm, select the “Phase Loss Threshold“ in the range: 60 to 90% of the
rated voltage set in the page “GRID TYPE”.
The percentage of the phase loss threshold is related to the detection of the regenerated
voltage on the lost phase.
The regenerated voltage has a lower value than the rated voltage, in particular:
•in delta system the regenerated voltage is up to 85% of the rated voltage,
•in star system the regenerated voltage is up to 70% of the rated voltage.
The recommended pre-set value is 85% for delta voltages.
Setting the threshold below 85% can cause insensitivity to the regenerated voltage, while
setting the threshold above 85% can cause excessive sensitivity to small network variations.
Considering neutral loss alarm, select the “Neutral Loss Threshold“ in the range: 10 to 30% of
the rated voltage set in the page “GRID TYPE”.
The percentage of the neutral loss threshold is related to the "distance" between the real
position of the neutral within delta voltages and the position in which it should be, i.e. at the
center of the delta voltages.
Considering measurements out of range alarm, DPD02 performs three measurements, each of
which has a validity range.
1. Voltage:
➢delta voltages, 208V-40% to 480V+15% (125V to 552V)
➢star voltages, 120V-40% to 277V+15% (72V to 318V)
2. Frequency: 50Hz-10% to 400Hz+10% (45Hz to 440Hz)
3. Asymmetry: 0 to 30%

11
The purpose is to signal the condition in which the input signals to the device are out of the
range in which the DPD is able to make a correct measurement with the required accuracy.
IMPORTANT NOTICE!
IT IS NOT RECOMMENDED TO CHANGE THE DEFAULT SETTINGS FOR EACH
PRIORITY ALARM IF YOU ARE NOT AWARE OF THEIR FUNCTION
In the “OUTPUT 1” and “OUTPUT 2” pages one or more of the previously set non-priority
alarms are associated with the outputs.
When multiple alarms are set, they are associated with the “OR” or “AND” logic functions.
The output relays can be configured as “Normally energized” or “Normally de-energized”.
When finished, press “Save” button on the bottom right to complete the setup.
A pop-up confirming the completion of the configuration process will appear.
Press “Done” button to proceed.
