the concentration during this period, because the tape is saturated.
The Monitor relay (RY6) will energize when monitoring is temporarily
suspended due to tape saturation. Note however, any one point
that is enabled for Duty Cycle will cause the Monitor relay (RY6) to
energize regardless if some points have not been selected (enabled)

Duty Cycle” bits default to TRUE, but can be set to FALSE with the
following procedure.
