CARLO GAVAZZI DPC02 Installation Instructions

TRMS 3-phase voltage and frequency
monitoring relay
DPC02
Connections
(*) F
Connect the 3-phase power supply and the
neutral (if present) taking care of the sequence.
Connect the relay output according to the rat-
ings.
Keep power OFF while connecting!

When the frequency runs out of the set window, for more than the set delay time, the "frequency" output relay (terminals 25, 26, 28) and the related yellow LED turn OFF, red LED (flashing 2 Hz during
the delay time) turns ON. If the phase sequence is wrong, or one phase is lost, the output relays release immediately (only 200 ms delay occurs). This failure is indicated by the red LED which flashes
5 Hz as long as the alarm condition is occurring.
Mounting
Hang the device to the DIN-Rail being sure that the spring closes. Use a screwdriver to remove the
product.

Ensure the input voltage range is correct. Adjust upper (
frequency window ( Hz ) on relative scale by turning the upper right dial. Turn the lower dials to set the delay times (0.1 to 30 s).
Turn power ON. The bi-colour bottom LED turns ON (green or red colour).
DPC02 operates when all 3 phases are present at the same time in the proper turning sequence, the voltage value is within the upper and lower set limits
and the frequency value is within a symmetrical window around the nominal frequency.
When one or more phases exceed the upper level, or drops below the lower level, for more than the set delay time, the "voltage" output relay (terminals
15, 16, 18) and related yellow LED turn OFF, red LED (flashing 2 Hz during the delay time) turns ON.
