Monitoring and Operating the Controller 4.8 Control Modes ATTENTION After changing a Local Setpoint value, if no other key is pressed, it then takes a minimum of thirty (30) seconds elapsed time before the new value is stored in non-volatile memory. If controller power is removed before this time, the new setpoint value is lost and the previous setpoint value is used at power-up. If, after changing the LSP value, another key is pressed, then the value is stored immediately. 4.8.
Monitoring and Operating the Controller 4.8.2 What happens when you change modes Table 4-8 Changing Control Modes (Dual Display Only) Control Mode Definition Manual to Automatic Local Setpoint The Local Setpoint is usually the value previously stored as the Local Setpoint. PV tracking is a configurable feature which modifies this. For this configuration, when the controller is in manual mode, the local setpoint value tracks the process variable value continuously.
Monitoring and Operating the Controller Switching between setpoints You can switch Local and Remote setpoints or between two Local setpoints when configured. ATTENTION The REMOTE SETPOINT value cannot be changed at the keyboard.

Monitoring and Operating the Controller 4.11 Accutune III Introduction Accutune III (TUNE) may be used for self-regulating and single integrating processes. This autotuning method is initiated on-demand, typically at initial start-up. There are no other requirements necessary, such as prior knowledge to the process dynamics or initial or post tune process line-out to setpoint or manual output.
Monitoring and Operating the Controller At the end of the tuning process, the controller immediately calculates the tuning constants and enters them into the Tuning group, and begins PID control with the correct tuning parameters. This works with any process, including integrating type processes, and allows retuning at a fixed setpoint. 4.11.1 Tune for Simplex Outputs After “TUNE” has been enabled, you can start Accutune as shown in Table 4-11.
Monitoring and Operating the Controller Configuration Check for Duplex See Subsection 3.6 - Accutune Set Up Group for details. Make sure: • TUNE has been enabled • DUPLEX has been configured to Manual, Automatic or Disabled 4.11.3 Using AUTOMATIC TUNE at start-up for Duplex (Heat/Cool) Used when DUPLEX has been configured for AUTOMATIC. This is the preferred selection for most Heat/Cool applications when tuning a new chamber.
Monitoring and Operating the Controller This selection results in performance tuning over the full range utilizing both Heat and Cool outputs to acquire blended tune values that are then applied to both Heat and Cool tuning parameters. Both PID sets are set to the same values. Table 4-13 Procedure for Using BLENDED TUNE at Start-up for Duplex Control Step 1 Operation Configure LSP1 2 4.11.

Monitoring and Operating the Controller 4.17 Setting Failsafe Mode Introduction You can set the Failsafe Mode to be Latching or Non-Latching.
Monitoring and Operating the Controller RUN/HOLD key You can start or stop the Ramp or Program using the RUN/HOLD key. 4.19 Setpoint Ramp Introduction When you have configured a SETPOINT RAMP, the ramp will occur between the current local setpoint and a final local setpoint over a time interval of from 1 to 255 minutes. You can RUN or HOLD the ramp at any time.
Monitoring and Operating the Controller Step Operation Press Result 6 End the Ramp When the final setpoint is reached, “RUN” changes to “HOLD” in the upper display and the controller operates at the new final setpoint. 7 Disable SPRAMP See Section 3 – Configuration group “SPRAMP” for details. Power Outage If power is lost during a ramp, upon power-up the controller will be in HOLD and the setpoint value will be the setpoint value prior to the beginning of the setpoint ramp.
Monitoring and Operating the Controller 4.21 Setpoint Ramp/Soak Programming Introduction The term “programming” is used here to identify the process for selecting and entering the individual ramp and soak segment data needed to generate the required setpoint versus time profile (also called a program). A segment is a ramp or soak function which together make up a setpoint program.
Monitoring and Operating the Controller Contents Definition ATTENTION Entering “0” will imply an immediate step change in setpoint to the next soak. Ramp unit The ramp unit selection determines the engineering units for the ramp segments. The selections are: • TIME = Hours:Minutes (XX:XX) Range: 0-99 hr.:0-59 min • EU-H = Degrees/Hour OR EU-M = Degrees/Minute (Range – 0-999) Soak segments A soak segment is a combination of soak setpoint (value) and a soak duration (time).
Monitoring and Operating the Controller Contents Definition ENABL = When the program is initially changed from HOLD to RUN the present PV value is captured and used as the beginning setpoint value for the ramp segment. If the program is terminated before completion, the setpoint value will revert back to the PV value captured at the initial HOLD to RUN transition.
