The first screen shows that five separate curves can be
edited. Selecting one of Curve 1-5 and pressing Edit will
display the screen where new curves can be assigned. The
type can be toggled between Linear and None.
Thirty-two points can be assigned by selecting one of the
points and pressing Edit. This allows the operator to
change the Millivolts and the corresponding Value by
clicking on each option. Pressing OK will save the point.
The Return button will return the user to the menu screen.
Alternate PID Setup
The Alternate PID Setup menu option allows for up to
16 sets of PID values to be used on the first loop via the
programmer.
This menu option is typically used for vacuum
applications with the programmer.
There is a choice of PID 1 – 16, and Loop 1 Set 1 – Loop
1 Set 3.
Prop Band (0 for On/Off)
This is the proportional band for the PID setup. P =
Proportional (Prop Band). This is a field in which you
want to stay around the setpoint. The range of values is
–32768.0 to 32767.0.
Reset
This is the reset value. I = Integral (Reset). This is the actual temperature being monitored over a period of
time and then averaged to keep within the Proportional band. The reset is in repeats per minute. This
affects the output of the controller. It will be proportional to the amount of time the error is present. This
helps to eliminate offset. The range is -32768.00 to 32767.00.
Rate
This is the rate value. D = Derivative (Rate). This is the sudden change or rate in the temperature. This rate
is in minutes. This affects the controller output which is proportional to the rate of change of the
measurement and will control the amount of output by time restraints. Thus derivative takes action to
inhibit more rapid changes of the measurement than proportional action. Derivative is often used to avoid
overshoot. The range is -32768.00 to 32767.00.
