Section 5
Ramp/Soak Operation
The 2104 controller features a Ramp/Soak Program.
The program consists of 16 intervals plus a standby
interval. The time span and setpoint for each interval
are individually adjustable. These intervals make up a
Ramp/Soak Profile. An example of a typical 8-interval
Ramp/Soak program is shown below.

Outputs
Event Outputs may be configured to turn ON or OFF
during each of the intervals. Event outputs are merely
timed outputs that are either ON or OFF during an
entire interval.
Examples of event outputs might be annunciation of a
soak interval, an indicator light or addition of a
product to the process. Outputs #3, #4 and #5 (if your
controller was purchased with these options) may be
setup as event outputs. For Outputs #3, #4 or #5 to be
used as Events, the output must be set up as an Event
on its setup page (i.e. OUT3). For example, for Output
#3 to turn on during interval 2, set menu 2E (interval
2 event) to E3 (Output #3 on). See page 43 for details.
