Y ou can select the state you want the outputs, controlled by the RBC, to be
set to whenever a communication error occurs. Previous models of the RBC
automatically set all outputs to off (0) when communication is lost. The A
version of RBCs allow you to either freeze the outputs in the state they were
in when communication was lost, or have the outputs set to off (0).
Energized parts could fail in an unsafe condition.
If the RBC fails or the system loses power , the outputs will go off (0)
regardless of the jumper selection.
This could cause damage to equipment or death or injury to
personnel.
