Execution
The execution of the ramp and soak feature is initiated through the Run/Stop parameter, (r-
S) in the Operation Mode. The Run/Stop parameter has four possible values.
If the Run/Stop parameter is set to rUn, the program will start to execute in order from step
0 of the start pattern.
If the Run/Stop parameter is set to Program Stop (PStP), the program will stop and maintain
the temperature of the last set point before the program was halted. When the Run/Stop
parameter is restarted, the program will restart and execute from step 0 of the start pattern.
The start pattern selection (Ptrn) is only available when the Run/Stop parameter is set to
Program Stop.
If the Run/Stop parameter is set to Program Hold (PHod), the program will be paused and
the temperature will be maintained at the set point temperature that was active prior to the
program hold. Once the Run/Stop parameter is set back to run, the program will follow the
step before the hold and start to execute through the rest of the program.
Display
During ramp and soak program control, the SV default display is P-XX, where P indicates
the current execution pattern and XX indicates the display item to Set Point Value (SP) or
Residual Time (r-ti). The Set Point Value will display the temperature set point of the current
execution step in the SV display. The Residual Time will display the remaining time of the
current execution step in the SV display. After selecting the Set Point Value or Residual
Time, the ENTER key must be pressed to accept the display change.
