Manual Proportional Integral Derivative (PID):
Allows the operator to manually input P, I and D parameters into the
controller. These parameters are fixed as long as the controller is in this
mode.
Slo, Nor, or Fast:
Heat/Cool PID quick tune pre-determined parameters. Selectable through
the keypad. See table below for Reference Settings.
Ramp/Soak
The controller is provided with a 16 segment, front programmable
Ramp/Soak feature. Unused alarms can be programmed as a segment.
Caution: Do not operate the auto-tune while a ramp/soak
function is operating.
Ramp/Soak is one of the many features that add process programming
capabilities to the M2B controller. This section will deal only with the
Ramp/Soak programming operation.
Basic Theory Of
Operation Ramp/Soak
The M2B controller is user friendly. It offers an easy way to program a ramp.
Instead of requiring the operator to calculate an approach rate, the M2B
does the calculation automatically. The operator needs to program the
target set point and the time desired to reach that set point. When the ramp
segment is executed by the controller, it calculates the ramp required to
reach the process temperature from starting set point to the programmed
set point in the time allowed.
Dwells (or soaks) are ramp segments with target set point equal to starting
process temperature. This allows for multistage ramps without wasting
intermediate soak steps.
IMPORTANT! Test any program for best results before running production
material.
