FINLSP 203 Enter a value within
the 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).

specific rate of change for any local setpoint
change.

setpoint rate option.

EUHRUP 205 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 change
in Setpoint (i.e., no rate applies).
