OVRD OVRD

INSTRUCTION NAME: OVRD (override)

DESCRIPTION:

This instruction causes the output of the station function (STAT) to perform

either output or integral tracking. When the value in operand 3 is 1, the STAT function output tracks

the value in operand 2. When the value in operand 3 is 0 and the value in operand 4 is 1, the STAT

function output performs integral tracking.

A controller in the AUTO, RSP, SUP, or DDC mode will perform output tracking if the value in

operand 3 is 1. A controller in manual mode will perform output tracking when operand 1 is enabled

and operand 3 is 1. (Normal manual mode operation will occur if operand 1 is disabled.) Output

tracking sets the output of the STAT function equal to the track value in operand 2.

A controller in the AUTO, RSP, or SUP mode will perform integral tracking when the value in

operand 3 is 0 and integral tracking is enabled (operand 4 = 1).

Note

To avoid loop windup in override control applications

for which integral tracking (operand 4) is enabled,

place a FIL function and a RGST function immediately

after the AOUT function of the loop containing the

signal selecting operation. The name of the general

operand 2 of the OVRD function.

Refer to section NO TAG (page NO TAG) for

instructions on determining the correct filter time

constant.

The OVRD function must precede the CNTRL function in the FST and cannot be used in the same

loop in conjunction with a cascade, track, or another override function. The SVA and SVD inputs

remain unchanged.
