Mode of Operation
DFB01 and PFB01 monitor
the frequency value of their
own power supply.
Example 1
(Non-latching mode - N.D.
relay)
The relay operates and the
yellow LED is ON as soon
as the measured frequency
exceeds the upper set level
or drops below the lower set
level for more than the set
delay time. The relay releas-
es when the measured fre-
quency comes back within
the upper and lower limits.
The red LED flashes until the
delay time has expired or
the measured value falls off
the limits.
Example 2
(Latching mode - N.E. relay)
The relay operates and the
yellow LED is ON as long as
the measured frequency is
within the upper and lower
limits.
The
relay
releases
latches in alarm position as
soon as the measured fre-
quency exceeds the upper
set level or drops below the
lower set level for more than
the set delay time. The red
LED flashes until the delay
time has expired or the
measured value comes back
within the limits. Provided
that
the
frequency
dropped below the upper
set level (minus hysteresis)
or exceeded the lower set
level (plus hysteresis), the
relay operates when the
interconnections
terminals Z1, Z2 or 8, 9 are
interrupted.
