IQ DATA
Section 5
APPLICATION CONSI DERATIONS
- This Section contains various considerations
5.0 General
to be kept in mind when applying the IQ Data to a specific
application. It is designed primarily for the systems or appli
cation engineer responsible for making up the wiring plan
drawings.
It is strongly suggested that all earlier Sections - especially
2 and 3
be read thoroughly before proceeding.
-
- A number of DIP switches,
5.1 DIP Switch Settings
located on the right rear side of the chassis, tailor each IQ
Data to a specific application. The switches provide 4 selec
tion groupings which must be set by the user during installa
tion. Once these settings are determined, they should be
recorded on a copy of the Installation Record Sheet, shown
in Table 4.A, page 19. The filled-in Record Sheet should then
be made available to the installation team and to maintenance
personnel. Paragraph 4.3 describes how to physically set the
switches.
5.1 .1 Current Transformer Ratio
provided external current transformers can vary from 25:5 to
5000:5. Switch
SW1, Nos. 1 thru 5
to the external current transformer's ratio, as listed in Table 5.A.
The AC line current level appear
5.1.2 Display C urrent-
ing in the Display Window is auto ranged to represent
amperes to kiloamperes.
The IQ Data can accept a line fre
5.1.3 Line Frequency-
quency of either 50 or 60Hz. Selection is made at
8.
Place the switch in the:
OFF position for a 50 Hz line
•
ON position for a 60 Hz line
•
- The ratio of the user
must be set to correspond
