Two-Hand Control inputs must connect either directly to a Two-Hand Control Block or indirectly through a
Bypass Block connected to a Two-Hand Control Block. It is not possible to use a Two-Hand Control input
without a Two-Hand Control Block.
Either the TC1 input or the OS1 input has turn Off authority.
OS1 needs to be in the Run state before TC1 can turn the output of T1 & SO1 On.
