Important: Switch 5 and 6 of S1 must remain in the OFF position for
normal operation.
If the 9/Series fiber optic I/O ring should fault or any other fault should
occur within the 1746 I/O rack, the 1746I module will attempt to maintain
all of its I/O in the same state condition. This holds all output devices in
the chassis to their present state. (Outputs already ON remain ON, outputs
already OFF remain OFF, and analog modules maintain their present
output voltage). This does not necessarily apply if the 1746I module is the
cause of the fault.
Wire your I/O devices accordingly considering all safety issues.
Three different fully equipped 1746 I/O chassis are available for the
9/Series I/O ring. See page 10A-49 for details on these I/O devices.
