Line Overvoltage Detection Level -
The
IQ
Data
Plus I I can be set to detect an overvoltage condition as a
selectable level. The available range is from 105 to 140% of
the nominal AC line voltage.
As
the result of a detected level,
the Trip and Alarm Relays may be actuated.
Switch
SW5, Nos.
1 , 2,
and 3
determine the detection level,
as shown in Table 6.0.
Note also that Switch
SW2, Nos.
1
and
2 determine the unit's
response to a detected overvoltage condition, as described
in Paragraph 6.1 .6.

Alternate Power Factor Calculation
- The standard
power factor calculation for the
IQ
Data Plus
II
is
Wf\(W2+Q2
for sinusoidal loads. If the user has a load waveform that is
nonsinusoidal (e.g. chopped) or a load that is extremely light,
37
the alternate calculation can be enabled with
SW5, No. 4.
Applications that may require the alternate calculation include
lighting loads, computer room monitoring, and loads at less
than 20% of the current transformer full load rating.
6.1.19
Auto Reset -
Setting Switch
SWS, No. 5
to the ON
position will enable the
IQ
Data Plus II to attempt an auto reset
based on any protective function. The unit will attempt to reset
itself 3 times in 3 seconds by monitoring the line and looking
for a fault. If the condition still exists, the IQ Data Plus
II
will
remain off-line until an operator resets it, either locally or over
IN COM.

Line Undervoltage Detection Level -
The IQ Data
Plus II can be set to detect an undervoltage condition at a
selectable level. The available range is from 60 to 95% of the
nominal AC line voltage. As the result of a detected level, the
Trip and Alarm Relays may be actuated.
Switch
SWS, Nos. 6,
7
and
8 determine the detection level,
as shown in Table 6.P.
Note also that Switch
SW2, Nos. 3 and 4
determine the unit's
response to a detected undervoltage condition, as described
in Paragraph 6.1 .7.
