FORCE SELF-POLAR
gives higher priority to forcing self-polarization as indicated in the logic diagram. This is consistent with the overall
philosophy of distance memory polarization.
The memory polarization cannot be applied permanently but for a limited time only. The self-polarization can be
applied permanently and therefore takes higher priority.
