Options and Wiring Diagrams
The LCI-90 can be configured for a wide range of signal input and output functions. Each
of these functions requires the instrument to have the correct menu settings (Section 5.0),
DIP switch settings (Appendix B), signal and power wiring, and in some cases, optional I/O
modules installed. The wiring diagrams are given in this Section; the optional I/O modules
are listed in Appendix D. The table below gives of a summary of the LCI-90 functions,
referenced to their associated menu and DIP switch numbers, required hardware options,
and section of this manual covering the wiring termination.
