Appendix B: 8LS-CP
System Configuration
The 8LS-CP uses a modified input with discreet components per carbon
input. Each CP input requires two loops. The 8LS-CP is factory
configured to contain between 1 to 4 CP loops. The unit must be ordered
for the number of CP inputs required per 8LS. Loops not used for the
CP input may be used as standard inputs.
The analog output of loops 7 and 8 can be used for recording analog
process signal representing the PV of loops 2 and 4 (carbon probe
inputs). This function is selected through the DIP Switch setting on the
CPU board. Position #4 must be On in order to use the PV recording
function.
