Alarm Value 1

This setting is used to indicate how many degrees

 

 

Mode (AL-1)

the process temperature will be allowed to exceed

 

 

 

the set point temperature. An alarm output will de-

Auto-Tune Mode

See Page 41 of Chapter 5 for instructions on how

 

 

(At)

to Auto-Tune your dryer.

 

 

 

Note: Although the controller is calibrated at

 

 

 

the factory, the manufacturer

 

 

 

recommends that the unit be Auto-

 

 

 

Tuned prior to dryer startup.

 

 

 

 

 

 

Temperature Input

This setting is used to offset an error between the

 

 

Shift Mode (TnS)

set point and the actual temperature. The entire

 

 

 

input range is shifted by a set figure

 

 

 

preprogrammed by the operator.

 

 

 

 

 

 

Proportional Band

This setting controls the amount in which the

 

 

Mode (P)

manipulated variable (MV) is proportionate to the

 

 

 

deviated value or controller error.

 

 

 

 

 

 

Integral Time

Setting this feature, gives the control an action that

 

 

Mode (I)

is proportionate to the time integral of the control

 

 

 

error. By using this setting, proportional action is

 

 

 

used in combination with integral action to offset

 

 

 

the control error and the set point will begin to

 

 

 

match the control temperature (PV or process

 

 

 

value).

 

 

 

 

 

 

Derivative Time

Setting the derivative control provides the

 

 

Mode (d)

controller with the ability to correct for a future

 

 

 

error in the previously set process output.
