1 General Specifications Model UT Digital Indicating Controller GS 0D01C0E General Model UT Digital Indicating Controller is an intelligent, microprocessor based digital indicating controller with powerful control capability and the userfriendly large numerical display. The UT features as standard many functions which are necessary for various control applications, and all of these functions such as control function, control computation function, signal computation function, etc. can be configured by using the keys on the front panel. The instrument has eight types of control strategies and also an overshoot suppressing function "SUPER" and a hunting suppressing function "SUPER " as well as an autotuning function built in as standard. Panel size is small, mm (width) mm (height), and designed for saving space. UT UTE E indicates the model with expanded functions. Main Features High resolution display of digits. Since LEDs of mm height are used for displaying measured values, the display is clearly read. The front panel size is mm (width) mm (height) and the depth is 0 mm, designed for saving space. Eight types of control function, including singleloop control, cascade control, loop control with autoselector, and loop control with hold function, enabling the operator to start control operation immediately after simply entering the settings. Parameter can be easily set using a personal computer. ("Parameter setting tool (model LL0)" sold separately is required.) Universal input and output enables users to set or change freely the type of measured inputs, measurement input range, type of control output, etc. from the front panel. Contact inputs (up to points) and contact outputs (up to points) Note can be employed and functions can be assigned to each contact (The maximum number of points varies depending on the specification code.) Note: See the Hardware Specifications and Contact Outputs described later. Various communication function are provided. Communication is possible with personal computer, programable logic controller, and other controllers. Functional Specifications Control Functions UT Mode The following types of basic control structure can be set as the UT mode by the user. Singleloop control (UT mode 1): The most simple and basic control function. Cascade primaryloop control (UT mode ): Output tracking function and cascade control logic are provided. Suitable for primaryloop cascade control. Cascade secondaryloop control (UT mode ): Setpoint output and the cascade control logic are provided. Suitable for secondaryloop cascade control. Cascade control (UT mode ): Dual control function for cascade control is available in a single instrument. Loop control for backup (UT mode ): Output tracking function is provided to back up another control instrument. The local and remote control outputs are switched by a contact input. Loop control with switching (UT mode ): Two measured inputs are switched for control depending on the status of contact input or measured input. Loop control with autoselector (UT mode ): Two measured inputs are automatically selected for control with a high, low, or average, or temperaturedifference value selector. Loop control with hold function (UT mode ): This control holds a input and a control output if an external sensor is switched. Control Computation Functions In each UT mode, the following control computation functions can be selected. Continuous PID control, Timeproportional PID control, and Relay ON/OFF control. Target setpoint and PID parameters: Maximum eight sets of target setpoint and PID parameters can be set. These eight sets can be set for both the main and slave loops in cascade control. Zone PID selection: Dividing measuring range into maximum zones by maximum reference points, PID parameter set switching in up to measured input zones. Autotuning: Available as standard. Possible to activate autotuning for both main and slave loops for cascade control. GS 0D01C0E Copyright Feb. 00 (YK) nd Edition Jul. 0 (YK)

2 Preset output function: When the instrument is in STOP mode, measured input is burntout, or an abnormality is found in an input circuit, a preset value is output as a control output. "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. Control cycle time Each cycle time can be selected under the following conditions.: 0 ms: Available for model code UT00, when UT mode is set to Singleloop control and the following functions are not used: "SUPER" function, "SUPER " function, input computation, setpoint rateofchange limiter, MV output rateofchange limiter, deviation alarm, sensor grounding alarm, fault diagnosis alarm, and FAIL output. 0 ms: Available when UT mode is not cascade control. 0 ms: Available when UT mode is cascade control. (Set value on shipped from the factory: 0 ms) Operation Mode Switching (Note: Communication enables all the following mode switching to be executed.) AUTO/MANU switching: Bumpless switching between automatic operation mode and manual control mode is available by using the front keys or contact input. The contact input has priority over front key input or switching by communication. The contact input is invalid for Cascade secondaryloop control or Cascade control. RUN/STOP switching: Switching by contact input (bumpless for switching from STOP to RUN). The contact input has priority over switching by communication. In RUN mode, control computation is activated. In STOP mode, control computation ceases and a preset value is output as a control output while other functions operate normally. OTE/LOC switching: Switching between remote setpoint and local setpoint by instrument operation or contact input. The contact input has priority over instrument operation or switching by communication. For remote to local switching, either bumpless tracking (employing the remote setpoint on switching as the local setpoint) or without tracking (directly switching the local setpoint) can be specified. CADE/AUTO/MANU switching: Switching by instrument operation or contact input. The contact input has priority over instrument operation or switching by communication. Valid for Cascade secondaryloop control or Cascade control. Output tracking ON/OFF switching: Provided for Cascade primaryloop control or Loop control for backup. External tracking signal and internal control output are switched by the contact input. The contact input has priority over the switching by communication.
