DPD

DPD DS ENG16/11/2017

3-phase Voltage and Frequency Monitoring with NFC

Description

DPD is a threephase multifunction configurable

monitoring relay suitable for both Delta and

Star mains. It protects loads from wrong phase

sequence, neutral and phase loss, additionally

voltage, frequency and asymmetry thresholds can

be set and provide output signals.

The DPD is delivered with factory default alarm

values, if they are not completely suitable they can

be modified according to own requirements.

DPD has two separate relay outputs.

3 front LEDs provide visual indication of outputs

states and alarm discrimination.

Through the DPD APP the user can reprogram

the unit at any time or check the device operation

status.

Benefits

• Flexibility and Versatility. 2 part numbers cover all

requirements in terms of mains type, voltage and

frequency values.

• 2 SPDT outputs. It is possible to provide 2 different

signals for different purposes.

• Plug & Play. DPD is available with 2 different factory

settings. Which are the most commonly used.

• Customized devices availability. DPD can be ordered

with customized settings also for very small quantities.

• NFC Communication. Through the NFC communication,

via smartphone, tablet or PC, the DPD can be configured

or provide real time operation data such as: alarms

status, voltage & frequency readings.

• High Compactness. The DPD features a large amount

of capabilities in just 22.5 mm.

Applications

DPD is suitable for all applications where it is necessary to monitor phase presence, correct phase sequence

and the voltage, frequency and quality of threephase load mains: lifts, escalators, HVAC, material handling,

pumps and compressors.

Operating Description

• Suitability

DPD can be used for power supply and mains quality monitoring of all threephase loads with supply voltage

from 102VAC to 552VAC. Monitoring function can be performed between Line to Line as well as Line to Neutral.

• Alarms

There are 2 types of alarms for the DPD: the "priority" alarms and the "non priority" alarms.

Priority alarms De-Energize both outputs at the same time when they are triggered:

• Phase loss

• Neutral loss ( only in "Star" configured systems )

• Wrong phase sequence

• Out of range measurement

Each one of the priority alarm can be disabled individually. The threshold can be set for the phase or neutral

loss.

Non priority alarms are totally configurable by user. Type of measurement to be monitored and trigger value

can be freely set, within the specified ranges, and changed any time:

• Undervoltage U<

• Overvoltage U>

• Overfrequency f>

• Underfrequency f<

• Threephase asymmetry

DPD

DPD DS ENG16/11/2017

Up to 10 virtual alarms among the above types can be configured. As there are only 2 outputs on the DPD,

certain alarms can be configured without being directly associated to an output.

• Delays

For each one of the Alarms it is possible to set an "Alarm ON" from 0 ( the device reaction time is though <0.2

s ) to 60 s. If the alarm cause restores before alarm ON delay elapsing no output signal will be provided. Alarm

OFF delay can be set from 0 s to 600 s.

Delays are only applicable for non priority alarms. Priority alarms are always immediate.

• Outputs

There are 2 SPDT Electromechanical outputs which can be associated to any of the alarms set. It is also

possible to associate 2 o more alarm by means of AND or OR operators to a specific output.

Each ones of the outputs can be configured as "Normally Energized" or "Normally De-Energized".

• Visual information

The DPD is equipped with 3 LEDs which provide the status information

• LED1 is lit when the Output 1 is energized

• LED2 is lit whne the Output 2 is energized

• LED3 is bicolor and can be blinking or fixed

1 red flash Phase or neutral Loss or phase sequence

2 red flashes Under/over-voltage

3 red flashes Under/over-frequency

4 red flashes Asymmetry

5 Flashes Out of range parameter

• NFC communication

DPD is equipped with built-in NFC communication.

With the DPD APP through the NFC communication it is possible to read or write the device configuration as

well as reading the voltage, the frequency or the alarms in real time.

NFC communication does not require any power for the device configuration.

DPDs can be configured without taking them out of the box.

Configuration

The configuration can be prepared on the PC or smartphone, downloaded from another device, by means of

NFC, or picked from file.

Once a configuration has been prepared on the PC it can be uploaded to one of more DPDs.

NFC also allows, when necessary to download the configuration from a device, modify it if necessary and then

upload it to another device.

It is possible to Lock the DPD in order to avoid tampering or unauthorized configuration. The locking/ unlocking

procedure is managed through one of the available apps.

• Operation flow

When powered, after Power On delay elapsing, until mains parameters are within all the alarms threshold

values, the DPD LED3 will be lit green (steady ).

If one of the mains parameters is exceeded the alarm ON delay elapsing starts, LED3 blinks green ( if a delay

is set, else immediately ), at the end of the delay the alarm associated output switches and LED3 flashes RED

( see visual information table ).

When the value, which was exceeded, returns to normal the delay OFF elapsing starts ( if a delay is set, else

immediately ), at the end of the delay the alarm associated output switches returning to original position. LED3

returns to steady green.

• Phase loss

Phase loss measurement is performed by comparing the 3 phases voltage values. If the voltage of one phase

falls below the set threshold, can be turned OFF if unwanted, ( default is 85%), compared to the other 2

phases, the alarm goes off. DPD detects loads regenerated voltage. Setting below the default value may cause

insensitivity to phase loss.

• Neutral loss

On Star connected loads if the neutral connection is lost the DPD detects the failure and goes into alarm.

Setting the neutral loss above the default value may cause, in case of a balanced load, insensitivity to neutral

loss.

This detection can be turned OFF if unwanted.

• Asymmetry

Asymmetry is an indicator of the mains quality, can be turned OFF if unwanted, and it is defined as the

absolute value of the maximum deviation among the mains voltages, divided by the nominal voltage of

the 3-phase system. The definition changes according to the voltage reference:
