TO 172838.
The standard unit requires 1 20/2 40 VAC control power to
operate. See Figure 2.1A (page 6). The unit mounted with a
three-phase Power Module draws its power from the line it is
monitoring.
1.3 Use of Manual-
This manual is designed for use during
installation and troubleshooting and, if necessary, unit re
placement. It also has information of specific importance for
the user's application engineer who is planning the overall
system and who is determining the setpoint values for a
specific IQ Data application.
The manual is broad enough in scope to form the basis of new
employee familiarization, refresher training sessions, and on
going maintenance.
IQ DATA
It is strongly advised that the application engineer carefully
read Sections 2 thru 5 before producing the application's wiring
plan drawings and filling out the Setpoint Record Sheet.
Installation teams should carefully read all of Section 4
before
starting final installation. Maintenance personnel should be
familiar with Section 7 before attempting to service the IQ Data.
1.4 Level of Repair
-
This manual is written with the as
sumption that only unit-level troubleshooting will be performed.
If the cause of malfunction is traced to an IQ Data, the unit
should be replaced with a spare. The malfunctioning unit
should then be returned to Westing house for factory repairs.

formatted messages to RS232C for use with other
RS232C compatible devices. No software is provided in
this case.
