PowerChoice Manufacture Default Power Condition Timer Values

timer value threshold of two minutes ensures the appropriate amount of background drive maintenance activities occur.
Attempting to set a timer values less than the specified minimum timer value threshold will result in an aborted EPC "Set
Power Condition Timer" subcommand.
