INPUT ALGORITHM 1

NUMBER OF TUNING PARAMETER SETS—This selection lets you choose one or two sets of tuning constants (gain, rate, and reset). NOTE: The Tuning Group is automatically configured to have two PID sets when a Duplex Control Algorithm is configured.

ONE SET ONLY—Only one set of tuning parameters is available. Configure the values for: Gain (proportional band), Rate, Reset Time, and Cycle Time (if time proportional is used).

TWO SETS KEYBOARD SELECTABLE—Two sets of tuning parameters can be configured and can be selected at the operator interface or by using the Digital Inputs.

Press this key until you see PID SET1 or PID SET2 then press

orto switch between sets. Configure the values for: Gain, Rate, Reset, Cycle Time, Gain #2, Rate #2, Reset #2, Cycle #2 Time

TWO SETS PV AUTOMATIC SWITCHOVER—When the process variable is GREATER than the value set at prompt SW VALUE (Switchover Value), the controller will use Gain, Rate, Reset, and Cycle Time. The active PID SET can be read in the lower display. When the process variable is LESS than the value set at prompt SW VALUE, the controller will use Gain#2, Rate#2, Reset#2, and Cycle#2 Time. The active PID SET can be read in the lower display.

TWO SETS SP AUTOMATIC SWITCHOVER—When the setpoint is GREATER than the value set at prompt SW VALUE (Switchover Value), the controller will use Gain, Rate, Reset, and Cycle. When the setpoint is LESS than the value set at prompt SW VALUE, the controller will use Gain #2, Rate #2, Reset #2, and Cycle #2.

ATTENTION Other prompts affected: SW VALUE

AUTOMATIC SWITCHOVER VALUE—This is the value of Process Variable or Setpoint at which the controller will switch from Tuning Constant Set #2 to Set #1.

LOCAL SETPOINT SOURCE—This selection determines what your local setpoint source will be.

LOCAL SETPOINT—The setpoint entered from the keyboard. TWO LOCAL SETPOINTS—This selection lets you switch

SP

between two local setpoints using the Select key.

THREE LOCAL SETPOINTS—This selection lets you switch

SP

between three local setpoints using the Select key
