Configuring Limits (IQ 260 Only)
Use this screen to assign
Limits
for the meter.
Functional Overview for Limits
:
Limits
are
transition
points
used to divide
acceptable
and
unacceptable
measurements. When a value goes
above or below the limit, an
out-of-limit condition
occurs. You can set and configure up to
eight Limits
for the
IQ 260 meter.
Once they are configured, you can
view
the
out-of-Limits
(or
Alarm
)
conditions
in the
Limits Polling
screen.
You can assign the
eight limits
to readings from
six groups
of parameters:
•
Readings
(Instantaneous Voltage; Instantaneous Current; Total and Per Phase Power and Power Factor;
Frequency; and Neutral Current)
•
Demand
(Current; Per Phase, Total Power and Power Factor)
•
Maximums
(Maximum values for all of the readings listed above, including (for IQ 260) THD voltage and
currents)
•
Minimums
(Minimum values for all of the readings listed above, including (for IQ 260) THD voltage and
currents)
•
Phase Angle
(For voltage and current)
•
THD
(For IQ 260, voltage and current)
From the
Tree Menu
