Installing the RTD

Probe

To install the RTD probe, screw the fitting body into the thermowell
with a 7/8” open-end wrench. While you apply pressure against the
sheath to force the tip of the RTD probe into the bottom of the
thermowell (so that the probe tip is in contact with the bottom of the
thermowell), tighten the 9/16” nut using an open-end wrench against
the 7/8” fitting body.

Software Configuration

To use data from the RTD you must include a CWM_ECPU board in
your ControlWave project using ControlWave Designer’s I/O
Configurator, and then configure it. See the ControlWave Designer
Programmer's Handbook
(D5125) for more information. That same
manual includes an I/O Mapping section that describes, for advanced
users, the I/O map for this board.
