When I/O channel communication to a Series 505 base is lost, the state of
the outputs is determined by the selection made on the 505 RBC jumper E1
(Off/Freeze). Figure 7 shows the location of the jumpers on the 505 RBC.
NOTE: You must make an E1 jumper selection on the 505 RBC. The RBC
Status Display reports an error if no jumper selection is made.
The jumpers on the 505 RBC headers E2 and E3 are for factory use only.
Header E4 is shipped without a jumper. Do not alter the default settings
unless instructed to do so by a Siemens Technical Support technician.
