NOTE:
Successful installa-
tion requires five
steps:
• Model number and
software choice
(Appendix);
• DIP switch set-
tings (Chapter 1);
• Sensor match
(Chapter 2 and
Appendix);
• Sensor installation
(Chapter 2); and
• Wiring (Chapter 2).
˜
NOTE:
Input-to-output iso-
lation is defeated
when the external
signal conditioner
power supply is
used to power a
transmitter connect-
ed to input 1.
˜
NOTE:
See Chapter 1 for
DIP switch location
and settings.
NOTE:
This output cannot
be configured as an
event ouput.
