Glossary of Terms
Application Any of the 28 (or more) equipment-specific purposes for which the
M
INI C HEF 2000 includes software programs. Each application has a number.
Automatic control One-touch cooking, which requires configuration of the prepro-
grammed menus.
Auto-tuning A time-saving feature, auto-tuning allows the controller to explore the
responsiveness of the system in order to determine an effective set of parameters for
PID control. To do this it crosses an auto-tune set point three times, then controls at the
normal set point using the new parameters.
Configuration Mode The level of programming in which equipment type features and
parameters are specified.
Convection Oven An oven that uses a fan to circulate heat and minimize cooking
times.
Cook and Hold Oven An oven that cycles between a cook cycle and a hold cycle in
order to maintain food at a servable temperature or maximize meat tenderness.
Deepfat Fryer A fryer that cooks food in large amounts of hot oil. Efficiency depends
on the fryer's power input, production rate, and the longevity of the cooking oil.
Derivative The rate of change in a process variable. Also known as rate. See PID.
DIN Deutsche Industrial Norms (DIN). A set of technical, scientific and dimensional
standards developed in Germany. Many DIN standards have worlwide recognition.
Griddle Good for crisping, browning and flavor development, griddles can be one-sided
or two-sided. Two-sided griddles (also called Clam Shell griddles) reduce cooking times
by cooking both sides of the food simultaneously.
Hysteresis A change in the process variable required to re-energize the control or
alarm ouput. Sometimes called switching differential.
Integral Control action that automatically eliminates offset, or droop, between set
point and actual process temperature. Inverse of Reset.
JIS Joint Industrial Standards, also Japanese Industrial Standards Committee (JISC).
Establishes standards on equipment and components.
Keys:
Down-arrow key (F) On the Protoyping/Training Overlay, the right key in the
bottom row, which allows user to move down the lists.
Edit key (A) On the Protoyping/Training Overlay, the left key in the top row,
which allows user to access the next level of parameters or values.
Enter key (B) On the Protoyping/Training Overlay, the center key in the top row,
which allows user to enter a chosen value and return to the previous level.
Escape key (E) On the Protoyping/Training Overlay, the center key in the bottom
row, which allows user to return to the original value, when editing a value.
Home key (D) On the Protoyping/Training Overlay, the left key in the bottom row,
which allows user to move directly to Operation Mode with a 2-second key press.
Up-arrow key (C) On the Protoyping/Training Overlay, the right key in the top
row, which allows user to move up the lists.
