SEL-734W and SEL-WCS
Product Overview
Integrated Radio
The 900 MHz radio module is mounted inside the SEL-WCS cone for environ-
mental protection. The radio communicates to a single SEL-734W to transmit
load data.
Dip Switches
The control DIP switches inside the housing allow easy selection of the identifi-
cation of each sensor. An SEL-WCS has a set of four DIP switches for a Network
ID, two DIP switches for a phase ID, and a single DIP switch that determines
whether an SEL-WSC sends the harmonic content information to the SEL-734W.

switches where you make the different settings from those on the SEL-734B.
Settings
Settings are made on both the SEL-WCS and the SEL-734W to make the infor-
mation sent by the SEL-WCS available and correct for use in the SEL-734W. The
Network ID setting is common to both devices. To use other settings, refer to the
information provided below on settings specific to each device.
For the SEL-734W to use the information from the SEL-WCS, the value selected
on the SEL-734W must match the value selected on the SEL-WCS. This setting
allows an SEL-734W to operate within the range of many SEL-WCSs, yet be
able to listen to the one(s) that are intended to be used with that SEL-734W.
