Turn the power ON. If everything is OK the “ALM” LED will be green lit. LED 1 and LED 2 (with default configuration) will be both yellow lit.

In case of alarm the LED “ALM” will flash RED. The number of flashes shows the type of alarm triggered.

Active alarms can also be displayed on the PC or smartphone through the DPD App.

As soon as, or after alarm OFF delay elapsing, the fault cause is eliminated the normal operation will be restored, no need to RESET.

Green ( ) / Red (ALM)	Green ON (steady)	Power supply ON
	Green flashing (2 Hz)	Alarm triggered but configured delay is elapsing
	Red, 1 flash	Phase or neutral loss or incorrect phase sequence alarm
	Red, 2 flashes	Under / over voltage alarm
	Red, 3 flashes	Under / over frequency alarm
	Red, 4 flashes	Asymmetry alarm
	Red, 5 flashes	Measure out of range alarm
	OFF	Power supply OFF
Yellow ( )	ON	Relay output energised
	OFF	Relay output de-energised

NOTE: power supply ( )and "ALM" alarm in the same LED.

There are 2 types of alarm:

Priority alarms
Description	Priority alarms trip both outputs at the same time when they are triggered.
Type	Phase loss Neutral loss (in "Star" configured systems) Incorrect phase sequence Out of range measurement
Configuration	Each one of the priority alarm can be disabled individually. The setpoint can be adjusted for the phase or neutral loss.

Non priority alarms
Description	Non priority alarms are totally configurable by the user. Type of measurement to be monitored and trigger value can be freely set, within the specified ranges, and changed at any time.
Type	Undervoltage U< Overvoltage U> Overfrequency f> Underfrequency f< Asymmetry
Configuration	Up to 10 alarms among the above types can be configured. As there are 2 outputs on DPD02, some alarms can be configured without being directly associated to an output. Logical functions like AND and OR can be used to connect several alarms to the same relay output.
