3. INSTALLING THE CONTROLLER

CAUTION

To prevent electric shock, the source of power to the controller must be turned off when mounting the controller on to a panel.

NOTE

To install the controller, select a location where:

1. No-one may accidentally touch the terminals; 6. There are no resulting magnetic disturbances;

2. Mechanical vibrations are minimal; 7. The terminal board (reference junction compen-

3. Corrosive gas is minimal; sation element, etc.) is protected from wind;

4. The temperature can be maintained at about 23°C 8. There is no splashing of water; and

with minimal fluctuation; 9. There are no flammable materials.

5. There is no direct heat radiation;

Never place the controller directly on flammable items.

If the controller has to be installed close to flammable items or equipment, be sure to enclose the controller in shielding panels positioned at least 150mm away from each side. These panels should be made of either 1.43mm thick metalplated steel plates or 1.6mm thick uncoated steel plates.

●Mount the controller at an angle within 30° from horizontal with

the screen facing upward. Do not mount it facing downward.

5. 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) For safety, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC60947) near the instrument so as to be operated easily, and clearly indicate that the device is used to de-energize the instrument.

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

IMPORTANT

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.

NOTE

• Always fix a terminal cover bracket to the UT150 controller before wiring if an optional anti-electricshock terminal cover (part number: L4000FB) is used.

• Two types of optional anti-electric-shock terminal covers (part numbers T9115YE and T9115YD) are available for the UT152 and UT155 controllers, respectively.

CAUTION

To prevent electric shock, the controller should be mounted on the panel so that you do not accidentally touch the terminals when power is being applied.

NOTE

The temperature controller is shipped with the parameters set at the factory-set defaults. Check the default values against the “Parameter Lists” in the following page (P.14, 15), and change the parameter settings that need to be changed.

This section explains how to set and register parameter values. The procedure for changing SP (target setpoint) and A1 (alarm 1 setpoint) can be found on “Changing Target

Setpoint (SP)” and “Changing Alarm 1 Setpoint (A1),” respectively. You can set the other parameters in the same way.

There are no setup displays for parameters specific to functions, such as the optional alarm output functions or heating/cooling control, if they were not selected at ordering.

The setting of some parameters (such as the control mode parameter CTL) determines whether the other parameters are displayed or not.

The flowchart (P.13) will help you understand how this works.

Step 2:

Press the or key to change the displayed SP value to the required value. In this example, SP is changed to 200°C.

The period flashes while the value is being changed.

Step 3:

Press the key once to register the setting. The period goes out. SP is now changed.

Step 1:

Confirm that the controller shows the operating display 1 during normal operation (PV and SP are displayed on the indicators).

Step 2:

To enter the operating parameter setting display, press the key for at least 3 seconds. If your controller has the /AL or /HBA option, the display for the Alarm 1 setpoint (A1) appears. {If not, control mode (CTL) appears.}

Step 3:

Press the or key to change the current A1 value to a required value. In this example, A1 is changed to 200°C.

This section describes the parameter functions specific to the UT150/UT152/UT155 temperature controllers. (The functions described in other sections of this manual and the general functions are not discussed.)

HYS

Control output / cooling-side control output cycle time

CT CTC

PV input filter

Select one from the following: a. Dynamic auto tune control (SLF)

(See note)

b. PID control (PID) c. On/off control (ONF) Note: Dynamic auto tune control is not available

for heating/cooling control. Read the section below this table to find out more about dynamic auto tune control.

You can set this parameter only for control without an integral action (when registered as CTL=PID and I=OFF). The controller outputs the manual reset (MR) value when PV=SP. For example, if you set MR=50%, the controller outputs (OUT) 50% when PV=SP.

For heating/cooling control, you can set the ratio between the cooling-side output and heating-side output. For example, if you set COL=2.0 and the heatingside output is 10% at a certain deviation (SP-PV), then the cooling-side output will be 20% when the cooling-side also reaches that deviation.

You can only set a deadband for heating/cooling control. In a positive deadband, there are neither heating-side nor cooling-side outputs. In a negative deadband, there are both heating-side and cooling-side outputs, which overlap each other.

The cycle time is the period of on/off repetitions of a relay or voltage pulse output in time proportional PID control. The ratio of the ON time to the cycle time is proportional to the control output value.

This function should be used when the PV display value may fluctuate greatly, for example, when the measured input signal contains noise. The filter is of the firstorder lag type, and FL sets the time constant. If a larger time constant is set, the filter can remove more noise.

SUPER function selection

This function adds a bias value to the measured input value, and the result is used for display and control computation.

PV value inside the controller

measured input value

PV bias+=

This function is useful for carrying out fine adjustment when the PV value is within the required accuracy but it differs from the value obtained by other equipment.

For DC voltage input, the input signal can be scaled for the particular engineering unit. For example, if you set the input type (IN) at range code 22, the initial range is 0.0 to 100.0.

Using DP, set the decimal point position fit for the

engineering unit you want to use. (In the example below, the 2 digits to the right of the decimal point)

Next, register the scale values of the measured input scale using

RH and RL. (In the example below, RH=10.00 and RL=0.00)

Initial scale

Measured input scale

(after being scaled)

egister the decimal point position using DP.

100.0 (5V)0.0 (1V)

10.00 (RH)0.00 (RL)

Using the SPH and SPL parameters, you can limit the setting range of the target setpoint (SP) within the measured input range(scale).

This function prevents SP from being mistakenly set at too large or too small a value (beyond the setting range).

To prevent a sudden change in SP, or to change SP at a constant rate, ramp-up and ramp-down rates can be set separately. This function operates at the following events. a. SP change b. SP1/SP2 switching c. Power-on At power-on, SP starts from the current PV value.

Set the ramp-rate time unit using parameter TMU.

The alarms are output as relay outputs. Since a relay has a limited life, excessive on/off actions will shorten the life of the alarm. To prevent this, you can set a hysteresis to prevent excessive on/off actions for both alarm 1 and alarm 2.

The SUPER function is effective in the following cases: a. An overshoot must be suppressed. b. The rise-up time needs to be shortened. c. The load often varies. d. SP is changed frequently. Note 1: The SUPER function will not work when

on/off control is selected, or I or D constants is set at OFF in PID control.

Note 2: For some types of systems, the SUPER

function may not be so useful. If this is the case, turn off the function.

■ What is Dynamic Auto Tune Control?

Dynamic auto tune control is one of the features offered by the temperature controller. When the controller is turned on or the process variable (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 variable (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.

IMPORTANT

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 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 the parameter CTL at PID.

• Set the PID constants at the factory-set defaults (P = (upper range-limit – lower range-limit) × 5%; I =

240 sec.; and D = 60 sec.)

• Set the parameter CTL at SLF. 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.

■ When Power Failure Occurred during Operation

● Momentary power failures of less than 20ms (or less than 1ms when ⬙/V24⬙ is specified) have no effect on

the controller operation (i.e., normal operation continues).

● For power failures longer than 20ms (or longer than 1ms when ⬙/V24⬙ is specifed), however the status will

be as follows. (The controller action at power recovery is the same as at power-on.)

• Alarm action: Continues (but alarms with a waiting action enter the waiting state once)

• Setting parameters : Maintained

• Auto-tuning: Canceled
