1 General Specifications MODEL 550 Digital Indicating Controller GS 05D0C00E General Model 550 Digital Indicating Controller is an intelligent, microprocessor based digital indicating controller with powerful control capability and the userfriendly large numerical display. The 550 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. It is suitable for a diverse range of applications, with positionproportional control model and heating/cooling control model also available E E indicates the model with expanded functions. Main Features Extralarge digital display allows the indicated values to be read even from a long distance. LEDs of 0 mm height are used for the process variable display. This is a fivedigit display for higher resolution. 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. Parameters can be easily set using a personal computer. ("Parameter setting tool (model LL00)" sold separately is required.) Universal input and enables users to set or change freely the type of inputs, input range, type of control, etc. from the front panel. In addition to standard type (universal ), the positionproportional type (relay ) or the heating/ cooling type (universal ) can be specified. Contact inputs (up to points) and contact s (up to points) can be employed and functions can be assigned to each contact. (The maximum number of points varies the suffix code.) Note: See Hardware Specifications and Contact Outputs described later. Various communication function are provided. Communication is possible with personal computer, programmable logic controller, and other controllers. Functional Specifications Control Functions Mode The following types of basic control structure can be set as the mode by the user. Singleloop control ( mode ): The most simple and basic control function. Cascade primaryloop control ( mode ): Output tracking function and cascade control logic are provided. Suitable for cascade primaryloop control. Cascade secondaryloop control ( mode ): Setpoint and cascade control logic are provided. Suitable for cascade secondaryloop control. Cascade control ( mode ): Dual control function for cascade control is available in a single instrument. Loop control for backup ( mode 5): Output tracking function is provided to back up another control instrument. The local and remote control s are switched by a contact input. Loop control with switching ( mode 6): Two inputs are switched for control depending on the status of contact input or input. Loop control with autoselector ( mode 7): Two inputs are automatically selected for control with a high, low, average, or temperaturedifference value selector. Loop control with hold function ( mode ): This control holds a input and a control if an external sensor is switched. Control Computation Functions In each mode, the following control computation functions can be selected: Continuous PID control, Timeproportional PID control, Relay ON/ control, Positionproportional PID control (for 550, 550 )and Heating/Cooling control (for 550 ). 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.

2 Zone PID selection: Dividing input range into maximum 7 zones by maximum 6 reference points, PID parameter set switching in up to 7 input zones. Autotuning: Available as standard. Possible to activate autotuning for both main and slave loops for cascade control. "SUPER" function: Overshoots generated by abrupt changes in the target setpoint or by disturbances can be suppressed. "SUPER " function: This 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, input is burntout, or an abnormality is found in an input circuit, a preset value is as a control. Sampling period Each sampling period can be selected under the following conditions: 50 ms: Available for model code 55000, when mode is set to Singleloop control and the following functions are not used: "SUPER" function, "SUPER " function, heating/cooling control, input computation, setpoint rateofchange limiter, MV rateofchange limiter, deviation alarm, sensor grounding alarm, fault diagnosis alarm, and FAIL. 00 ms: Available when mode is not cascade control. 00 ms: Available when mode is cascade control. (Set value when shipped from the factory: 00 ms) 500 ms: Always available. Operation Mode Switching (Note: Communication enables all the following mode switching to be executed.) AO/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 as a control 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/AO/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/ switching: Provided for Cascade primaryloop control or Loop control for backup. External tracking signal and internal control are switched by the contact input. The contact input has priority over the switching by communication.
