6. HI RANGE:3

Defines the high end of the range for output 3 in engineering units. Does not

appear for type CTRL.OUT.

R –9999 to 99999

D Dependent on the process variable range

7. TYPE:4

Defines what is to be retransmitted for output 4

D PV This refers to the linearized process variable

• SETPOINT This is the target setpoint

• RAMP SP This is the ramping, or actual setpoint, when the

setpoint is ramping

• CTRL. OUT This is the control output value

8. LOW RANGE:4

Defines the low end of the range for output 4 in engineering units. Does not appear

SELF TUNE

1. TYPE

Defines the type of self tuning algorithm that is available.

• PRETUNE Allows the operator to initiate Pretune only

• ADAPTIVE Allows the operator to initiate Adaptive Tune only

• BOTH Allows the operator to initiate both Pretune and

Adaptive Tune

D DISABLED Both Pretune and Adaptive Tune are disabled

2. PRETUNE

Defines the type of pretune algorithm that is available.

D TYPE 1 Normally used with slower thermal processes

• TYPE 2 Normally used with faster fluid or pressure processes

• TYPE 3 Normally used with level control applications

3. TUNE PT.

Defines the PV value at which the output will switch off during a TYPE 1 pretune.

Helps prevent overshoot.

R Any value in PV input range

D AUTOMATIC (Controller defines this point, low end for Automatic)
