6.1 .6 Overvoltage Detection Response
-
Should an over­
voltage condition be detected, the IQ Data Plus II can control
the internal Trip and Alarm Relays in 4 ways:
•
Activate trip relay
•
Activate alarm relay
•
Activate both trip and alarm relays
•
Activate neither trip and alarm relays
Switch SW2, Nos. 1 and 2 determine the response of the unit,
as listed in Table 6.D.

Note also that the Switch SW1 , No. 7 determines whether the
response is instantaneous or a selectable time interval, as
described in Paragraph 6.1.4. Switch
SW6, Nos. 5, 6, 7 deter­
mine the time interval, in seconds, as described in Paragraph
6.1.23. Switch
SW3, No. 8 disables or enables all of the over­
voltage and undervoltage protective capabilities, as described
in Paragraph 6.1 .12.

6.1 .7 Undervoltage Detection Response
-
Should an
undervoltage condition be detected, the IQ Data Plus II can
control the internal Trip and Alarm Relays in 4 ways:
•
Activate trip relay
•
Activate alarm relay
•
Activate both trip and alarm relays
•
Activate neither trip and alarm relays
Switch SW2, Nos. 3 and 4 determine the response of the unit,
as listed in Table 6.E.
