2.7 Programmable SV Control Mode
The temperature setting value is not fixed but a setting curve defined by users according to their requirements. By way of
PID control, the temperature input rises along with the defined temperature curve. The device provides 8 patterns and
each pattern with 8 steps, a linking parameter, a loop parameter, and a number of execution steps respectively. Each step
has 2 parameters (temperature setting value and time). After setting these parameters up, each temperature controller will
have its own set of initial pattern and step for creating its own temperature setting curve. Some of the terms are explained
as follows:
1. Initial pattern: set the program to start running at a sequential number of patterns.
2. Initial Step: set the program to start running at a sequential number of steps.
3. Running time: set the temperature duration time, if not necessary, it can be set to 0.
4. Step: includes 2 parameter settings: a setting point X and a Running time T, indicating the setting value (SV) to rise to
X degree after the time T. If the setting point X is identical to the previous setting, this process is called a Soak,
otherwise a Ramp; therefore this control procedure is also called a Ramp Soak control. The first running procedure is
preset as a Soak control, to set the temperature control to setting point X degree in advanced and keep the
temperature at X degree, at a duration time of T.
5. Number of loops: Extra loops to be carried out for the pattern. If set to 1, the pattern will be carried out 2 times.
6. Executing step: Number of steps executed for each pattern.
7. Execution: Before execution, users need to set up all the parameters. If the setting control is in the running mode, the
program will start running from the initial pattern and initial step, carrying out commands one by one by their set
orders. When the setting control is in the ending mode, the SV will stop at the final setting. When the setting control is
in the stop mode and the temperature will be at the value before the stop, by re-selecting to run, the program will start
running from the initial pattern and initial step. When the setting control is in the pause mode and the temperature is at
the value before the pause, by re-selecting to run, the program will start running from the step where the program was
paused, carrying out the remaining parts. During execution, the SV cannot be set up.
2.8 ERROR LED Indicator
When the analog input channel out of range is detected, the error code will show up and the error LED will also blinking to
notify. Users can disable this functionality to inactivate the error LED blinking, but the error code will still show up.
