•An On Time ≥ Off Time setting cannot be made.
(See segment 3C in the figure.)
•An On Time or Off Time is valid only within a segment and cannot straddle
segments. In the next segment, the On time and Off time set for that segment are
valid. (See segments 4 and 5 in the figure.)
Thus an On Time and Off Time setting made at the end of a RAMP-X segment
are ignored. (Compare segment 9 with the G.SOAK wait in segment 10 in the
figure.)
Note, however, that an On Time or Off Time setting at the end of a RAMP-T
segment is either valid or invalid depending on the computational error.
•When the On Time is set to 0 (no Off Time being set or set to more than 0), the
output goes on when the On Time becomes 0. If the output was on at the end of
the previous segment, it stays on and does not go off momentarily between the
two segments. (See segments 5 and 6 in the figure.)
•The G.SOAK Time is not included in the On and Off Time. (See segment 7.)
Nor is the Wait Time included for a G.SOAK that occupies an entire segment.
