Isolated Guarded Digital Output Module (T3485)
PD - 6034 Mar - 06 15
Fault Mode Jumper
The fault mode jumper is located behind the ID switch cover
in the lower left - hand corner of each I/O chassis. The position
of the fault mode jumper determines the module's response to
system level faults. The fault mode jumper’s position will
cause all output modules in the I/O chassis to either shutdown
(turn off all outputs) or to hold (hold the last state) after a
system level failure occurs. An example of a system level
failure is the failure of two processor modules.
Keying
The I/O chassis can be physically keyed to prevent accidental
damage caused by inserting a module into a slot wired for a
different module type. Figure 9 illustrates how the slot keys
are installed on the I/O chassis slot field wiring connectors.
The slot key positions for the isolated Guarded output module
are listed in Table 3 .
