Definition

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).

SETPOINT RATE— Lets you configure a specific rate of change for any local setpoint change.

SP Ramp and SP Programming must be disabled.

DISABLE SETPOINT RATE— Disables the setpoint rate option.

ENABLE SETPOINT RATE— Allows the SP rate feature for Loop 1.

ENABLE SETPOINT RATE 2— Allows the SP rate feature for Loop 2.

ENABLE SETPOINT RATE 12— Allows the SP rate feature for Loop 1 and Loop 2.

RATE UP— Rate up value for Loop 1. 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).

RATE DOWN— Rate down value for Loop 1. 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 change in Setpoint (i.e., no rate applies).

RATE UP—Rate up value for Loop 2. 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.
