WATLOW Series 982 User’s Manual 2 . 1 1 Installation and Wiring, Chapter 2
˜
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).
