Temperature control optimization
PID parameters for temperature
control
The mixer vessel temperature for the XDUO mixer is controlled by the temperature
control loop (TC_163) in the local control software. The default PID parameters for the
temperature control are designated for the TCU models recommended by GE. The default
PID parameters provide a stable mixer vessel temperature across the full weight range.
If the XDUO mixer is always used for a specific contents weight, or if a different TCU is
used, the vessel temperature control can be optimized for these conditions. The PID
parameter values shown in the table below are given as starting points for further opti-
mization of the temperature control.
