Parameter
Definition
RESET TO BEGINNING OF SETPOINT
PROGRAM— When enabled, this selection allows
you to reset via the keyboard to the beginning of the
program and resets the Recycle value to 0. The
program mode is placed in HOLD.
If the current Local Setpoint 1 value is at any value
other than that Setpoint value used in the first Soak
segment in the program, then the program will restart
at the current Local Setpoint 1 value and at the
beginning of the first Ramp segment in the program.
If the current Local Setpoint 1 value is at the same
Setpoint value as that used for the first Soak
segment in the program, then the first Ramp
segment is skipped and the program will restart at
the beginning of the first Soak segment in the
program.
RERUN CURRENT CYCLE—When enabled, this
selection allows you to reset the program via the
keyboard to the beginning of the current cycle. The
Recycle value is not affected. The program mode
(RUN or HOLD) is not affected.
HOT START—This feature allows the SP Program
to start at the current PV value rather than the
current Setpoint value.
Segment #1 Ramp Time or
Segment #1 Ramp Rate
ATTENTION This parameter is affected by the
RAMPUNIT configuration (see above). All ramps will
use the same selection.
PID Set Selection
ATTENTION The PID Set Selection prompts will
only show up when PID SETS in the Control 1 or
Control 2 Setup Group is set to 4 KEYBD. See
Section 3.17 (Control 1) and Section 3.18 (Control
2).
Segment #2 Soak Setpoint Value
Segment #2 Soak Duration
Guaranteed Soak Deviation Value For Soak
Segment #2—The number selected will be the PV
value (in engineering units) above and below the
setpoint outside of which the Soak Segment timer
halts. A value of 0.000 is equivalent to no
Guaranteed Soak.
