MODEL UT750 Digital Indicating Controller (with Custom Computation)

GS 05D01B02-01E

■ General

Model UT750 Digital Indicating Controller is an intelligent, micro-processor based digital indicating controller with powerful control capability, custom computation function and the user-friendly large numerical display. The UT750 features many functions which are necessary for various control application as standard, 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 specifies thirteen types of control strategies built in and also the overshoot suppressing function "SUPER" and a hunting suppressing function "SUPER 2" as well as an auto-tuning as standard.

■ Main Features

• Extra-large digital display allows the indicated values to be read even from a long distance. LEDs of 20 mm height are used for the process variable display. This is a five-digit display for higher resolution.

• User-friendly full dot LCD display. Not only the target setpoint and other control related parameters but also a deviation trend record or a deviation analogue bar can be

displayed.

• Thirteen types of control function, including single-loop control, cascade control, loop control with PV autoselector, and custom computation control, enabling the operator to start control operation immediately after simply entering the settings.

• Custom Computation function, which allows users’ own configuration for signals, enable them to realize such functions as complicated computation for input compensation or sequence logic.

( “Custom Computation Building Tool <model name:

LL200> is necessary to use this function.)

• Universal input and output enable users to set or change freely the type of measured inputs (thermocouple, RTD, or DCV), measurement input range, type of control output (4 to 20mA current, voltage pulse, or relay contact), etc. from the front panel.

• Equipped with seven contact inputs and outputs each, which are further expandable up to 23 inputs and outputs each by adding contact I/O signal expansion modules.

• Various communication function are provided. Communication is possible with personal computer, programable logic controller, and other controllers.

GS 05D01B02-01E

1st Edition Mar. 2000 (YG)

<<Contents>> <<Index>>

Loop control with PV auto-selector and two universal

inputs (UT mode 15): 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 21):

Can be provided by the user using the optional LL200 custom computation building tool.

● Control Computation Functions

In each UT mode, the following control computation functions can be selected.

Continuous PID control, Time-proportional PID control, Position proportional PID control(UT750-1 ■ position-proportional type only), Relay ON/OFF 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 PV zone. Maximum seven zones can be set for selection.

Auto-tuning:

Available as standard. Possible to activate auto-tuning for both loops of Cascade control, Dual-loop control, and Temperature and humidity control.

“SUPER” function:

Overshoots generated by abrupt changes in the target setpoint or by disturbances can be suppressed.

“SUPER 2” 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 output 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 output as a control output.

Control cycle time:

Each cycle time can be selected under the following coditions

50ms: Available when model code is "UT750-00",

UT mode is set to Single-loop control, and the following function is not used. “SUPER” function, “SUPER 2” function, Heating/Cooling control, measured input computations, setpoint rate of change limiter, output rate of change limiter, deviation alarm, sensor grounding alarm, fault-diagnosis alarm, FAIL output.

30.

500ms: Available when the amount of computation

module of Custom computation function is more than 30.

(Set value on shipped from the factory: 200ms)

Operation Mode Switching

(Note: Communication enables all the following mode switching to be excuted.)

AUTO/MANUAL switching:

Bump-less switching is available. Switching between AUTO and MANUAL 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. Bump-less switching from STOP to RUN is available. In RUN mode, control computation is activated. In STOP mode, control computation is ceased and preset output value is output as a control output, while other functions are operated normally.

REMOTE/LOCAL 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 bump-less 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.

CASCADE/AUTO/MANUAL 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 secondary-loop control” or “Cascade control” .

Output tracking ON/OFF switching:

Available when UT mode is set to “Cascade primary-loop control” or “ Loop control for back-up”. Switching between External tracking signal and internal control output can be realized by external contact.

■ Function Block Diagram for Custom Computation

The UT750 controller comes with built-in 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 output 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 output signals. These calculations include not only the four arithmetic operations and logical operations but also ten-segment linear approximations, temperature and humidity computations, temperature-based correction coefficient computations, pressure-based 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 output contacts.

Custom computations are configured using the given methods of block connection, as shown in Figures below.

Description

Note: Using an optional custom computation building tool (Model LL200-E10) that runs on a personal computer, you can build a variety

of computation (eg., four arithmetic operations, logical operations, ten-segment linearizer computations, temperature compensation factor computations, and pressure compensation factor computations) to be applied to the controller’s I/O signals.

Standard accessories: Brackets (mounting hardware), unit label, User’s Manuals, and User’s Manual (reference) (CD-

ROM version).

Specify suffix code according to the designated UT mode.
