11.4.2 Parameters That Apply to the Entire Multi-Step Ramp/Soak Recipe
11.4.2.1 Specifying the Optional Recipe Holdback
Parameter Name
: Recipe Holdback (83)
Name as Displayed
:
HLd.bHLd.b
Used By:
all controllers
When Displayed:
always
Range:
thermocouple and RTD input types:
off
0.1 to 100 °F
0.1 to 55.6 °C or °K
linear input types:
off
1 to 100 (See Note 1 below.)
Default:
10
Description:
Used to specify the maximum number of units that the controller
will allow the setpoint to differ from the process value before
“stopping the clock” on the ramp time or soak time. The
controller will “hold back” the SV until the PV differs from the SV
by no more than the holdback value.
Effect on Other
Parameters:
When a holdback has been configured, the ramp times and soak
times are used as minimum times.
Note 1: The range is reduced when a linear input is used and the value of the dSPLdSPL
(display) menu dEC.PdEC.P (decimal position) parameter is not 0 (zero). See 4.3.2 for more
information about the effect of a linear input on numerical ranges.
11.4.2.2 Specifying What Happens at the Conclusion of the Multi-Step Recipe
Execution
Parameter Name
: Termination State (84)
Name as Displayed
:
tEr.StEr.S
Used By:
all controllers
When Displayed:
always
Choices:
dEFtdEFt normal mode using default setpoint (setpoint displayed
on front panel)
LAStLASt normal mode using last setpoint reached in the recipe
StbYStbY put controller in standby mode
Default:
put controller in standby mode
Description:
Used to specify what happens at the conclusion of the ramp
time.
Effect on Other
Parameters:
No effect on other configuration parameters. Does affect
setpoint and controller mode of operation. Applied only if the
recipe runs to completion. If the operator terminates the recipe
execution by changing the controller mode, the setpoint used will
be the setpoint in effect when the operator changed the mode.
