RAMP/SOAK CONFIGURATION
The RAMP/SOAK feature of the TC-720 is highly complex, and it has not been completely tested and verified to be error-free
at this time. Its feature is enabled though so that the user can take full advantage of the controller’s features and
capabilities. If you intend to use this feature, use caution and verify that the ramp/soak program you use works as you
intend it to.
Clicking on the “CONFIGURE RAMP/SOAK” OK button calls up the following screen:
The Ramp/Soak configuration contains 8 program steps. Each step has settings for the following:
1. Set Temp.—the set temperature that the controller should maintain
2. Ramp Time—the approximate amount of time the controller should take to reach the set temperature
3. Soak Time—the amount of time the controller should maintain the set temperature before proceeding to the next
step
4. (P)roportional, (I)ntegral, (D)erivative—these are the control stability parameters used for the given set point
temperature
5. Go To Step--determines which step should be run after completion of the repeats. Go To Step can only be to the
same or a lower segment. No skipping forward is allowed. The Go To Step parameter needs to be used in
conjunction with the Repeats parameter.
6. Repeats—specifies how many times a given set of steps is performed before moving on to the next step.
Remember, this is the number of repeats IN ADDITION TO the first-time completion of the number of steps, so the
total number of times the steps will be completed will be the number of repeats plus one (N+1).
The TIMER MODE can be configured to use the set temperature or the sensor temperature. If the timer mode uses the set
temperature, then the amount of soak time, for example, begins counting as soon as the program step begins regardless of
the actual temperature of the sensor. If the sensor temperature is used, then the time will begin counting only when the
actual temperature of the sensor has reached the set temperature. However, the MAXIMUM TEMPERATURE DELTA FROM
TIMER can be set to allow timing to begin as soon as the Temperature Delta (or difference) between the actual sensor
temperature and the set temperature is within the specified range. The allowable range for the Temperature Delta is
0.00 °C to 20.00 °C.
