Operation Level

	Indicator	Name	Description

		Run/Stop Mode	When “RUN” is selected, the control is running.
		(r-S)	When “STOP” is selected, the control is stopped.
			When the control is stopped, the STOP display
			lights. The default is set to “RUN.”

		Mode (AL-1)	the process temperature will be allowed to exceed
			the set point temperature. An alarm output will de-
			energize the heaters.

Adjustment Level

	Indicator	Name	Description

		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.
