FINAL SP
Within setpoint limits
SETPOINT RAMP FINAL SETPOINT—Enter the
value desired for the final setpoint. The controller will
operate at the setpoint set here when ramp is ended.
ATTENTION If the ramp is on HOLD, the held
setpoint can be changed by the ▲ and ▼ keys.
However, the ramp time remaining and original ramp
rate is not changed. Therefore, when returning to
RUN mode, the setpoint will ramp at the same rate
as previous to the local setpoint change and will stop
if the final setpoint is reached before the time
expires. If the time expires before the final setpoint is
reached, it will jump to the final setpoint.
ATTENTION SP RAMP and SP RATE will cause
the SP portion of Accutune to abort. PV Tune will
continue to function normally. Ramp is placed into
HOLD while tuning (TUNE configuration).
HOTSTART
DISABLE
ENABLE
DISABLE—LSP1 is used as the initial ramp setpoint.
ENABLE—Current PV value is used as the initial
ramp setpoint.
SP RATE
SP Rate operates
only when both SP
Ramp and SP
Programing are in
HOLD mode or when
both SP Ramp and
SP Programming are
disabled.
DISABLE
ENABLE
SETPOINT RATE—Lets you configure a specific
rate of change for any local setpoint change.
DISABLE SETPOINT RATE—Disables the setpoint
rate option.
ENABLE SETPOINT RATE—Allows the SP rate
feature.
EU/HR UP
0 to 9999 in engineering
units per hour
RATE UP—Rate up value. When making a setpoint
change, this is the rate at which the controller will
change from the original setpoint up to the new one.
The ramping (current) setpoint can be viewed as
SPn in the lower display.
Entering a 0 will imply an immediate step change in
Setpoint (i.e., no rate applies).
EU/HR DN
0 to 9999 in engineering
units per hour
RATE DOWN—Rate down value. When making a
setpoint change, this is the rate at which the
controller will change from the original setpoint down
to the new one. The ramping (current) setpoint can
be viewed as SPn in the lower display.
Entering a 0 will imply an immediate step change in
Setpoint (i.e., no rate applies).
