Profile Parameters
The following settings apply to the entire profile.
Name
•
User-entered identifier for the profile. The name follows the profile when it is saved in a file
or moved to another controller.
Password
• User-set code that must be entered prior to editing a protected profile. A password may
consist of up to ten characters, may include letters, numbers or symbols and is case sensitive.
Guaranteed Soak Deviation/Guaranteed Soak Values
• The amount by which the actual chamber temperature or humidity is allowed to differ from
the set point for steps with Guaranteed Soak Enable set to On . In such steps when the actual
chamber temperature or humidity differs from the set point by more than this value, the step
timer stops running until the actual chamber temperature or humidity returns to within the
band defined by the set point plus or minus this value. Each profile can have its own set of
Guaranteed Soak values.
Data Logging
•
Check “Log Data while the profile is running” to automatically initiated data logging during
this particular profile.
Step Parameters
The following parameters set the behavior of a profile’s steps. Only the parameters that apply to
the selected step type appear in the step detail.
Step Type
Set the behavior of the step. Step Type options include:
•
Rate:
adjusts the temperature or humidity set point at the user-set Rate of change until it
reaches the step’s Set Point.
• Soak: maintains the temperature or humidity set point constant for the step’s Time.
• Jump: repeats previous steps in the profile starting at the step set with Jump to Step for the
Number of Times set. This option is not available for step 1.
• Ramp Time: adjusts the temperature or humidity set point gradually from the previous set
point to the step’s Set Point over the step’s Time.
•
State:
sets the temperature or humidity set point to the step’s Set Point without ramping from
the previous set point and holds that set point for the step’s Time.
• Instant Change: sets the temperature or humidity set point to the step’s Set Point without
ramping from the previous set point and holds that set point for the step’s Time.
• Wait For Process or Event: holds the profile until the specified conditions on the event
inputs are met. When multiple conditions are specified, the profile will not proceed until all
the conditions are satisfied at the same time.
• END: Sets the temperature/humidity set points, and event output conditions when the profile
ends.
