ASuL and ASLL are Program mode parameters that can be used to establish upper and
lower setpoint values outside of which the Auto Tune feature will not function. The Auto Tune
feature will not function if the process value is greater than ASuL or below ASLL.
Auto Tune Time Limit
This feature is used to automatically abort the Auto Tune function if the control response
calculations have not been completed within the time allotted.
Balanceless Transfer
This feature prevents changes in proportional output when changing from the Manual to
Control mode of operation. When transferring from the manual mode to the control mode, the
proportional outputs will be "Balanceless" regardless of whether the unit is inside or outside
the proporitonal band. This only holds true if the Auto Reset (ArSt) value is greater than 0.
Bumpless Transfer
This feature prevents changes in proportional outputs when changing from the Control to the
Manual mode of operation.
Choice of Control Algorithm
This Program mode parameter is used to select the control algorithm that will be used for Auto
Tune calculations.
Control selections are PID, PI, or P only . PI is the factory default.
Control Algorithm
A pre-programmed series of instructions that are used by the instrument when
determining the status of the output(s).
Control Response Criteria
This Program mode parameter selects the type of control response desired for the application
when using the Auto Tune feature.
The control response selections are from 1.0 for 1/4 wave decay response to 2.0 which is a
damped response.
