The active AR mode is memorized (latched) on power cycling. This means that the relay uses the last-used mode on
power-up. The AR mode resets to the default mode (specified by the AR MODE setting) when any settings in the autore-
close function are changed.

In addition, the current AR mode is available as FlexLogic Operands because AR Mode equals to 1, 2, 3, and 4 respec-
tively so that it can be monitored and logged.
