Display Parameter Selection
Damping Low
Normal
High
Autotune
Damping Menu
Note: The damping parameter specifies how aggressively the
controller performs its autotuning. The “Normal” setting is a
compromise between the fast recovery and overshoot. The
“Low” setting provides faster recovery, but with the possibil-
ity of overshoot; the “High” setting a slower recovery, but with
minimum or no overshoot.
Recipe (Ramp/
Soak) Menu
Single Setpoint Ramp Time
This selection will cause the controller to ‘ramp’ the
process from the starting point (current process value)
to the setpoint in the time specified. This ramp will take
place at startup when selected from the Ramp/Soak menu.
The setpoint must be at least ±0.2% of sensor span for the
ramp to be employed.
Multi-Step Ramp
This selection will enable the programming of a recipe (make
all ramp/soak recipe variables visible). Recipes can be resumed
on startup if interrupted by a power failure or initiated, held, and
terminated from the front panel via the Mode Menu or with the
logic input option (initiate and held/resumed only).
Holdback Band
Specifies the maximum number of degrees above or below
setpoint that the process can be for the segment timer to keep
going. The timer will hold while the process settles back into the
band and then continue. If this feature is not desired, this param-
eter should be set to which will disable it.
Termination State
This parameter determines what the control will do at the
completion of a recipe. Last Setpoint refers to the last
temperature specified in the ramp/soak recipe. Default
Setpoint refers to the standard setpoint which was in effect prior
to recipe initiation.
Recycle Number
Specifies the number of times after the first time that the recipe
is run before the program terminates.
