PROPORTIONAL BANDWIDTH

Proportional Band is the amount of deviation of the controlled variable

required to move through the full range (expressed in % of span or degrees

of temperature). It is an expression of Gain (the wider the band, the lower the

gain.) This item is accessible within the Menu. This PID control parameter is

adjustable from 0.1 to 999

RATE

Rate is a control function that produces a corrective signal proportional to

the rate at which the controlled variable is changing. Rate action produces a

faster corrective action than proportional action alone. Also referred to as

Derivative action, Rate is useful in eliminating overshoot and undershoot.

This item is accessible within the Menu. This PID control parameter is

adjustable from 0.0 to 999.

RESET

Reset is a control function that produces a corrective signal proportional to

the length of time and magnitude the controlled variable has been away from

the setpoint. Reset action accommodates load changes, and is also known

as Integral action. This item is not accessible within the Menu as the Reset

parameter tracks the Rate parameter by a fixed ratio.
