2 Loop control with autoselector and two universal inputs (UT mode 5): Process variable for loop control is automatically selected from two or three measured inputs by an internal selector, with using two universal inputs and an auxiliary analogue input. When two universal inputs are configured as measured input, auxiliary analog input can be used for a remote setting input. Custom computation control (UT mode ): Can be provided by the user using the optional LL00 custom computation building tool. Control Computation Functions In each UT mode, the following control computation functions can be selected. Continuous PID control, Timeproportional PID control, Position proportional PID control(ut750 positionproportional type only), Relay / control, Heating/ Cooling control. Target setpoint and PID parameter: Maximum eight sets of target setpoint and PID parameters can be set and stored in a instrument. For Cascade control and Dual Loop control type, eight sets for each main and slave are available. Zone PID selection: Sets of PID parameters can be selected according to zone. Maximum seven zones can be set for selection. Autotuning: Available as standard. Possible to activate autotuning for both loops of Cascade control, Dualloop control, and Temperature and humidity control. SUPER function: Overshoots generated by abrupt changes in the target setpoint or by disturbances can be suppressed. SUPER function: The function stabilizes the state of control that is unstable due to hunting, etc. without requiring any change in PID constants, when the load and/or gain varies greatly, or when there is a difference between the characteristics of temperature zones. Preset function: When the instrument is in STOP mode, measured input is burnout, or abnormality is found in an input circuit, users preconfigurable preset value is as a control. Control cycle time: Each cycle time can be selected under the following coditions 50ms: Available when model code is "UT75000", UT mode is set to Singleloop control, and the following function is not used.

AUTO/MANU switching: Bumpless switching is available. Switching between AUTO and MANU mode can be realized by using front key or by external contact, and external contact switching has priority to a front key operation. When UT mode is set to Cascade secondaryloop control or Cascade control, switching can not be realized by external contact. RUN/STOP switching: Switching of RUN/STOP can be realized by external contact. Bumpless switching from STOP to RUN is available. In RUN mode, control computation is activated. In STOP mode, control computation is ceased and preset value is as a control, while other functions are operated normally. REMOTE/LOC switching: Switching between local setpoints and remote setpoint can be realized by instrument operation or external contact, and external contact switching is prior to instrument operation. For remote to local switching, either with bumpless tracking ( to make the local setpoint value equivalent to the Remote setpoint value upon switching.) or without tracking(to switch directly to local setpoint in the instrument) can be specified by the parameter. CADE/AUTO/MANU switching: Switching can be realized by instrument operation or external contact, and external contact switching is prior to instrument operation. Available when UT mode is set to Cascade secondaryloop control or Cascade control. Output tracking / switching: Available when UT mode is set to Cascade primaryloop control or Loop control for backup.

11 Function Block Diagram for Custom Computation The UT750 controller comes with builtin control functions and various controller modes (UT modes) that provide different I/O computing functions. These modes are designed to support their respective control applications. From these choices, you can choose one that best meets your application needs. In some control applications, however, you may want to execute special computations based upon specific input data or have a contact of a specific data item in a specific control sequence. To be able to meet these needs, the UT750 controller provides a separate controller mode with which you can freely program your own computations. Computing functions available in these modes are referred to as custom computations. Custom computations allow you to perform a variety of calculations based on input and signals. These calculations include not only the four arithmetic operations and logical operations but also tensegment linear approximations, temperature and humidity computations, temperaturebased correction coefficient computations, pressurebased correction coefficient computations, and so on. For example, you can use the four arithmetic operations to apply the desired type of correction to input signals, or use a logical operation to program a sequencing process that works between input and contacts. Custom computations are configured using the given methods of block connection, as shown in Figures below.
