• An On Time ≥ Off Time setting cannot be made.

• An On Time or Off Time is valid only within a segment and cannot straddle seg-
ments. 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.

An On or Off Time that is set to be

longer than the segment time
is not valid.
Output-OFF
• 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.
