11.3 Configuring Single-Setpoint Ramp Parameters
11.3.1 Specifying the Ramp Time for a Single-Setpoint Ramp
Parameter Name:
Single-Setpoint Ramp Time (41)
Name as Displayed
:
S.S.r.tS.S.r.t
Used By:
all controllers
When Displayed:
if the recipe option is single-setpoint ramp
Range:
1 to 9999 minutes
Default:
1
Description:
Used to specify the time period over which the setpoint will be
ramped at start up from the starting process value to the
configured setpoint.
11.3.2 Specifying the Optional Recipe Holdback for a Single Setpoint Ramp
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. 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 single-setpoint ramp
time is used as a minimum ramp time.
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.
