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.
2.7 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.

2.8 RS-485 Communication Setup for DVP02TK-S
2.8.1
MODBUS Communication Protocol
For DVP02TK-S series, MODBUS supports formats such as RTU and ASCII. When RTU is selected, the data length is 8
and the following function codes are supported.
Function code 03: read multiple words, up to 32 words can be read.
Function code 06: write a single word.
Function code 10: write multiple words, up to 32 words can be written.
2.8.2
Restore to Factory Settings
Users can restore the RS-485 communication settings back to defaults (9600/7/1/E, station number 1) by switching RUN
to STOP and then STOP to RUN after turning on the device within 5 seconds.
2.8.3
RS-485 Communication Setup
There are 2 methods to setup RS-485 communication, via TK Wizard and setting the MODBUS address.
•
TK Wizard (TKSoft): click the Module Information and set up baud rate, transfer mode and then click "Send" to
save the settings.
