• With rate of rise programming, the settings are made in blocks of
two segments, so the final soak time cannot be set if the Number of
Segments Used parameter is set to an odd number. Therefore, the
final segment will be a soak segment if the Number of Segments
Used parameter is set to an even number and will be a ramp
segment if set to an odd number.
If the rate of rise setting is changed in the middle of a segment, the
segment time for the ramp period changes as well as the rate of rise
for the present SP.

• In the above diagram, the increased rate of rise results in a shorter
time for that segment.
• Similarly, if the SP is changed, the segment time for the ramp period
is also changed.
• If the soak time is changed, only the segment time for the soak
period is changed.
This section describes the parameters used during program operation.
• An advance operation moves to the start of the next segment.
• An advance operation moves forward to the end of the present
segment each time the Advance parameter is set to "ON." The
Advance parameter turns OFF once the next segment has been
reached.
• An advance operation cannot be executed during reset.
• A hold operation forces the program to maintain steady-state control
at the segment set point.
• The timer is stopped when the Hold parameter is set to "ON" and
restarts when the Hold parameter is set to "OFF."
