D-10 Upgrading Existing Series 500 Installations
With the PPX:500–5114A RBC you can select the state of the outputs
whenever a communication error occurs. Previous models of the RBC
automatically set all outputs to off (0) when communication is lost. You
must configure the RBC to freeze outputs in the state they were in when
communication was lost, or to have them set to off (0).
The Series 500 output modules in the remote base have a selection switch
for the state of the outputs during a communication loss (Figure D-4). If the
output modules in the remote base have a selection switch, the freeze
selection will override the output module's selection.
NOTE: If the RBC fails or the system loses power, the outputs will go off (0)
regardless of the jumper selection.
