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.
