DESCRIPTION OF TEMPERATURE CONTR OL

■ Temperature Controller

The temperature controller is used to keep the fixed temperature of such as a furnace (controlled object). In general, the temperature controller has temperature indicating display and setpoint setting display, generates a control signal according to the difference between a indicating value (measured temperature value) and SP to finally make the temperature agree with SP.

Sensors such as thermocouple (TC) or RTD can be connected for measuring a temperature. And output types such as rela y output or current output (4 to 20mA) are prepared according to the operating terminal (heater, valv e, and the lik e) that actually controls a temperature.

■ Types of Temperature Contr ol Action

ON/OFF action is the simplest action among the control actions. ON/OFF action of the internal thermostat keeps the optimum temperature. But the temper ature control output fluctuates in the fixed cycle with ON/OFF action. If this temperature cycle causes a problem, the control action that changes the output in proportion to the deviation (the difference between the target setpoint and present value) can giv e a better control performance. Thus the control action that moves the function part in proportion to the deviation is referred to as a proportional action (P action). But a steady-state deviation (offset) is inherently unav oidab le with proportional action alone. Though the manual reset can remove the offset, the same thing can be done using the control action together with the Integral action (I action) that will integrate the deviation as long as the deviation exists . This combination is ref erred to as a proportional-plus-integral action (PI action). It is the popular control method among the process control actions.

On the other hand, the derivative action (D action) is the action that changes the output in proportion to the rate-of-change of deviation. Since the output of derivative action depends on not the amount of deviation but its rate-of-change, the larger the rate-ofchange is, the more intensive corrective action the controller takes to correct the process response in advance. Setting each optimum value with the PID action consisted of these three actions enables a stable control quickly.

1-2

■ Dynamic A uto Tune Control

The Dynamic Auto Tune Control is the function to automatically determine the optimum PID constants for continuing a good control when the controller is turned on or the control conditions are unstable. This control method is gentle to the controlled object itself because a disturbance needs not to be set forcibly lik e Auto tuning.

In Dynamic Auto Tune Control, the controller automatically monitors the behavior and determines the optimum PID constants when (1) at power on, (2) the output travels up to 100% or down to 0% and remains there after changing a setpoint, (3) process begins oscillating by disturbance and the like. The principle of Dynamic A uto Tune Control can be relied on because it is based on Geglar/Nichols’s control method.

Refer to “6.5.1 Dynamic Auto Tune Control” on Page 6-6.

• Pressing the key for 3 seconds or more in the operating display retrieves the operating parameter setting display. You can transfer to the setup parameter setting display form the operating parameter setting display.

• Pressing the key for 3 seconds or more in either an operating or setup parameter setting display transfers back to the operating display.

Data display (red)

• In the operating display, either PV (measured value) or SP (target setpoint) is indicated. Which parameter takes precedence over the other depends on the parameter "DSP" value.

• In the parameter setting display, either the parameter codes or parameter value is indicated.

• If an error occurs, the error code is displayed.

Output (OUT) display lamps (Left: orange; right: green)

Lit while control output is being output. Flashes according to the control output value during timeproportional output. value is small; flashes fast when control output value is large.)

• The left lamp lights up in orange during control output of standard type.

• In heating/cooling control, the left lamp lights up in orange when the heating-side output is active; while the right lamp lights up in green when the cooling-side output is active.

Data change keys

• When PV is displayed in the operating display, a press of the or key switches to the SP display.

• When a parameter code is displayed, pressing either key once displays the parameter value (which can then be changed).

• Changes SP and the parameter values.

• Pressing the key decreases the data value and

pressing the key increases it. Holding down the key will gradually increase the speed of the change.

Deviation

"Proportional band" is defined as the

•

amount of change* in input (or deviation), as a percent of span, required to cause the control output to change from 0% to 100%.

Because a narrower proportional band

•

gives greater output change for any given deviation, it therefore also makes the control performance more susceptible to oscillation. At the same time, a narrower proportional band reduces the offset.

Reducing the proportional band to its

•

smallest limit (proportional band = 0%) results in ON/OFF control. UT100 series controllers select ON/OFF control using the parameter "CTL".

Note that the unit of proportional band

•

is the percent of PV input span, or actual temperature in engineering units. For UT100 series, set the actual temperature.

required to develop, when a stepwise change in deviation is imposed, an output change due to integral action that is exactly equal to the change due to proportional action. The longer the integral time set, the slower the change in output; the smaller the time, the faster the output changes.

6.3.2 T uning the Integral Time

To manually adjust integral time

The main goal is to reduce the offset

•

Adjust from longer time to shorter time

operating parameter "MR" (Manual reset) to remove the offset.

Shortening the integral time, like

narrowing the proportional band, will cause the measured temperature to begin oscillating. However, oscillation due to integral action is characterized by a longer period than that of oscillation due to narrow proportional band.

If the control object has a large time

•

constant or dead time the corrective action will be too slow with proportional action or proportional-plus-integral action alone, causing overshoot. However, even just sensing whether the deviation is on an increasing or a decreasing trend and adding some early corrective action can improve the controllability. Thus the derivative action ("D" action) is action that changes the output in proportion to the deviation derivative value (rate-ofchange). The parameter that sets how the derivative action will operate is the derivative time (D).

The derivative time (D) is defined as

•

the time required with "PD" action to develop, when a constant-slope-change in deviation is imposed, an output change due to derivative action that is exactly equal to the change due to proportional action.

Dynamic auto tune control is one of the

"Dynamic Auto Tune Control" is a sort of self-tuning

Dynamic Auto Tune Control is effective in the following cases:

(1) When the output travels up to 100% or down to 0% and remains there at power on; (2) When the output travels up to 100% or down to 0% and remains there after changing a setpoint; (3) When the process begins oscillating by disturbance and the like

features offered by the temperature controller. When the controller is tuned on or the measured input (PV) starts "hunting", this mode of control monitors the behavior of the PV and/or OUT (control output value) to automatically determine the optimum PID constants. This means that the PID constants may be changed automatically. If this is not desirable for your system, operate the controller in the normal "PID control". If you want to automatically determine the PID constants at the initial startup of the controller, first define the target setpoint (SP) and then turn the controller off once and then back on again. Do not use Dynamic auto tune control for a system where there is interference or continual disturbances.

Precautions

To use Dynamic auto tune control,

(1) be sure to turn on the final control element, such as a heater, before starting the control, and (2) make sure that the controlled loop is a closed loop.

If you do not follow these precautions, improper PID constants may be written into the controller. If this occurs, carry out the following:

•

Set PID for the parameter "CTL".

•

Set the factory-set defaults [ P = (upper range(scale)-limit — lower range (scale)-

limit) x 5%; I = 240sec; and D = 60sec ] for the PID constants.

•

Set SLF for the parameter "CTL".

If the control still doesn t work properly, stop using the Dynamic auto tune control function. Change the parameter "CTL" setting to PID and execute auto-tuning to obtain the PID constants.

(1) In principle, auto tuning must be used. (2) Turn PID parameters in the order of P, I, D. Adjust a numeric slowly by observing the result, and keep notes of what the progress is. (3) Gradually reduce P from a larger value. When the measured value begins to oscillate, stop tuning and increase the value somewhat. (4) Also gradually reduce I from a larger value. When the measured value begins to oscillate (with long period), stop tuning and increase the value somewhat. (5) Gradually increase D from a smaller value. When the measured value begins to oscillate (with short period), stop tuning and lower the value slightly.

If the optimum PID values are being

used, then use of the "SUPER" function yields stable control without overshoot even on setpoint changes.

As a result, temperature up-ramps

follow the programmed pattern more closely, giving more consistent product quality.

"Overshoot" is not only a matter of

•

temperature exceeding the setpoint, but also of prolonged instability and slow settling resulting from the undershoot that occurs in reaction to the overshoot.

SUPER effects (2)

Due to the gain changes that occur at

•

the transition from ramp to soak, conventional controls are inevitably prone to overshoot. Yet, if the PID constants are set so that the output stabilizes more quickly in order to avoid overshoot, the temperature ramp will lag behind the prescribed pattern.

By using the "SUPER" function, the

temperature up ramp can be made to follow the pattern almost exactly, and significant savings can be achieved.

8.3 Wiring

CAUTION

1) Before you start wiring, turn off the power source and use a tester to check that the controller and cables are not receiving any power in order to prevent electric shock.

2) Wiring should be carried out by personnel with appropriate electrical knowledge and experience.

NOTE

1) Use a single-phase power source. If the source has a lot of noise, use an isolation transformer for the primary side and a line filter (we recommend TDK’s ZAC2205-00U product) for the secondary side. When this noise-prevention measure is taken, keep the primary and secondary power cables well apart. Since the controller has no fuse, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC standards) and clearly indicate that the device is used to de-energize the controller.

2) For thermocouple input, use shielded compensating lead wires. For RTD input, use shielded wires which have low resistance and no resistance difference between the 3 wires. See the table given later for the specifications of the cables and terminals and the recommended products.

3) The control output relay cannot be replaced even though it has a limited service life (100,000 relay contacts for the resistance load). Thus, an auxiliary relay should be used so that the load can be turned on and off.

4) When using an inductive load (L) such as an auxiliary relay and solenoid valve, be sure to insert a CR filter (for AC) or diode (for DC) in parallel as a spark-rejecting surge suppressor to prevent malfunctions or damage to the relay.

5) When there is the possibility of being struck by external lightening surge, use the arrester to protect the instrument.

8-7

IMPORTANT

Always fix a terminal cover bracket to the UT130 controller before wiring if an optional anti-electricshock terminal cover (part number: L4000FB) is used.
