Mode of Operation

Connected to the 3 phases

(and neutral) DPB01 and

PPB01 operate when all 3

phases arepresent at the

same time, the phase

sequence is correct (not N

versions) and the phase-

phase (or phase-neutral)

voltage levels are within set

limits.

If one or morephase-phase

or phase-neutral voltages

exceeds the upper set level

or drops below the lower set

level, the red LED starts

flashing 2 Hz and the output

relay releases after the set

time period. In any case if

phase-neutral measurement

is selected both phase-

phase and phase-neutral

voltages are monitored. If

the phase sequence is

wrong or one phase is lost,

the output relay releases

immediately.

Only 200 ms delay occurs.

The failureis indicated by

the red LED flashing 5 Hz

during the alarmcondition.

Example 1

(mains network monitoring)

The relay monitors over and

under voltage, phase loss

and correct phase

sequence.

In case of N versions, the

relay monitors over and

under voltage.

Example 2

(load monitoring)

The relay releases in case of

interruption of one or more

phases, when one or more

voltages drop below the

lower set level or exceed the

upper set level.

Note

When DPB01 or PPB01 is used with phase indicator lamps (see examples in the following diagrams), the lamp H1 or H2

might be dimly lit when there is a phase loss in L1 or L2. This might happen if the lamps used are the typical low power indi-

cator lamps, and there are no other loads present.

This fact can be avoided by using W4 models. Note that the neutral must be always connected to the device.
