6.2.2.6 Maximum
Spike Correction Table
Figure 6-23 Maximum Spike Correction Table
The maximum spike correction table is used to prevent excess temperature overshoot in the
particular situation of Paddle Control and Boat Out.
Due to cold cleanroom air entering the process tube when the boat is out the door zones
measured by the paddle thermocouple will cool down. Without the maximum spike
correction table filled the DTC would respond with power increase for the affected zones.
When the boat is moved in the latent heat provided by this DTC action results is a large
temperature overshoot and subsequent longer stabilization times. With the maximum spike
correction table filled (default 6.0
C) the DTC is allowed only the stored value (6.0
C)
temperature rise on the spike TC, thereby limiting the latent heat and reducing temperature
overshoot and stabilization times upon door closure.
