SL0

PID values are preset for a slow response process.

nor

PID values are preset for a normal response process.

FASt

PID values are preset for a fast response process.

ArUP

Anti- Reset Windup Feature: Select

0n

or

0FF

.

0n

When

ArUP

is

0n

the accumulated Reset Offset value will be

cleared to 0% when the process input is not within the Proportional
Band.

0FF

When

ArUP

is

0FF

, the accumulated Reset Offset value is retained

in memory when the process input is not within the Proportional
Band.

ArtE

Approach Rate Time: Select

0FF

,

0.01

to

99.99

minutes. The function

defines the amount of Rate applied when the input is outside of the
Proportional Band. The

ArtE

time and the

rtE

time are independent and

have no effect on each other. To increase damping effect and reduce over-
shoot set the approach rate time for a value greater than the natural rise time
of the process (natural rise time = process value time to set point).

Fint

Fuzzy Logic Intensity: Select

0

to

100

%. 0% is OFF (disables Fuzzy Logic).

The function defines the amount of impact Fuzzy Logic will have on the
output.

Fbnd

Fuzzy Logic Error Band: Select

0

to

4000

°F, °C, or counts. Sets the band

width of the Fuzzy Logic. Set

Fbnd

equal to PID proportional band (

Pb1

) for

best results.
