Deadband
In on/off temperature control, it is the band above or below the setpoint
where there is no output action, It has the effect of moving the apparent
setpoint.
Derivative (Rate)
Adjusts the controller gain quickly in response to load changes.
Derivative Action
Is normally used to give a fast response to changes in process value and to
improve process stability. Alternatively derivative action may be configured
to act on the error signal which is useful in ramping applications.
Direct Action
Control action such that the output increases as the process value
increases.
Failsafe State
Designates the percentage of power output that the controller defaults to
after it detects a loop break condition and after the loop break time has
elapsed.
Filter (in Display
Menu)
Changes the filtering speed for the process value display only. It does not
affect control. This parameter is mainly used to slow down the flickering of
the display when the decimal position chosen is greater than zero.
Filtering (in Input
Menu)
Sets the time period over which the process value is averaged.
Hysteresis
In on/off temperature control, hysteresis represents the band where the
output changes state from deactivated to activated. It prevents chattering
around the setpoint and prevents rapid output cycling.
Hold
The freezing of a running program, in time, for the duration of the condition.
Integral (Automatic
Reset)
Slowly adjusts the position of the proportional band (range of power output)
to eliminate offset error.
Local/Remote
Alternative selections of the working setpoint. Either a value stored within
the controller (local) or an analog signal brought into the controllers rear
terminal (remote).
Loop Break
A condition where the input is not changing or responding properly to the
output action. This could be caused by a thermocouple or input failure, or a
heater or load failure.
Loop Break Time
The time interval from when the controller detects a loop break condition
and the initiation of the failsafe state.
Manual Reset
An adjustment that moves the proportional band up or down by a fixed
percentage so that more or less power is applied at setpoint. It is used to
eliminate offset error.
