GENERAL FEATURES:
The unit has two front dial settings. The upper dial is used for the
three phase nominal voltage settings that exists in the application.
The lower dial setting is for an adjustable time delay to prevent
nuisance tripping of the unit. The FW has a space saving 45mm
wide DIN-rail mount/surface mount enclosure and LED power-on
and relay status indication.
OPERATING PRINCIPLE:
In a 3-phase network, the FW simultaneously monitors phase
sequencing, loss of phase with a maximum regeneration rate
of 70% of the displayed by a potentiometer on the front face,
and the voltage drop on the 3 phases of less than 15% of the
preset value. When the 3 phases suceed one another, the
output relay is activated and indicated via a yellow LED. The
output relay de-energizes (LED off) after a time delay T,
adjustable between 0.2 and 10 seconds on the front face,
if one of the following faults is present :
- reversed direction of phase rotation
- absence of one or more phases
- voltage drop
