These controllers provide a multi-segment/multi-profile Ramp and Soak mechanism with the additional
ability to link multiple profiles together to implement extended sequences.
Although the term ‘RAMP’ is used to indicate the process variable change, there is no restrictions on the
direction of change. The Target Setpoint may be above or below the Current process variable for each
cycle within a sequence.
Figure 15. Ramp & Soak Current Process Variable.
The Ramp and Soak times are provided in 1-second increments and may span from 1 second to 99
hours, 59 minutes, 59 seconds. Internally, the time values are tracked within 0.1 second intervals.
The Ramp and Soak function attempts to provide a controlled increase to the process variable such that
the target setpoint is reached within the specified time. Options are provided to track the specified
RAMP time, the specified SOAK time or the overall CYCLE time.
