5. no direct radiant heat is present,

6. no magnetic disturbances are caused,

7. no wind blows against the terminal board (reference junction compensation element),

8. no water is splashed,

9. no flammable materials are around,

Never place the controller directly on flammable items or equipment. If the controller has to be installed close to flammable items or equipment, be sure to provide shielding panels all around the controller, at least 150mm away from every side; the panels should be made of either 1.43mm-thick metal-plated steel plates or 1.6mm-thick uncoated steel plates.

● Installation Position

Install the controller at an angle within 30° from horizontal with the front panel facing upward. Do not install it facing downward. The position of right and left sides should be horizontal.

■ How to Install

Turn off the power to the controller before installing it on the panel because there is a possibility of electric shock.

CAUTION

After opening the mounting hole on the panel, follow the procedures below to install the controller:

1. Insert the controller into the opening from the front of the panel so that the terminal board on the rear is at the far side.

2. Set the brackets in place on the top and bottom of the controller as shown in the figure below, then tighten the screws of the brackets. Take care not to overtighten them.

1.3 How to Connect Wires

1) Before carrying out wiring, turn off the power to the controller and check that the cables

to be connected are not alive with a tester or the like because there is a possibility of electric shock.

1-5

CAUTION

2) Wiring must be carried out by personnel who have basic electrical knowledge and

practical experience.

NOTE

1) Provide power from a single-phase instrument power supply. If there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: ZAC2205-00U from TDK) on the secondary side. As a countermeasures against noise, do not place the primary and secondary power cables close to each other.

2) For thermocouple input, use shielded compensating lead wires for wiring. For RTD input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires. The cables to be used for wiring, terminal specifications, and recommended parts are as shown below.

3) Control output relays may be replaced. However, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load.

4) The use of inductance (L) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a CR filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load.

2.12 Description of Multiple Setpoints and PID

The UT550/UT520 has a maximum of eight target setpoints, and has PID for each of these setpoints. The following shows the correspondence between the target setpoint numbers (SPN), target setpoints (SP), and PID parameters. For example, if you have set “2” to the target setpoint number (SPN), the control parameters available are target setpoint (2.SP), proportional band (heating-side proportional band) (2.P), integral time (heating-side integral time) (2.I), derivative time (heating-side derivative time) (2.D), cooling-side proportional band (2.Pc), cooling-side integral time (2.Ic), and cooling-side derivative time (2.Dc). To use multiple target setpoints, see the table below to check the corresponding parameters.

ber how to carry out an operation during setting, press the seconds. This brings you to the display (operating display) that appears at power-on.

3.1 Monitoring-purpose Operating Displays Available during Operation

The monitoring-purpose operating displays available during operation are roughly classified into two groups depending on the types of controller and control output.

See “3.8 Switching between AUTO and MAN,” to change to AUTO and “3.7 Switching between Run and Stop,” to change to Run.

NOTE

When on-off control is being used, auto-tuning cannot be carried out. Moreover, do not perform auto-tuning when controlling any of the following processes.

• Control processes with quick response such as flow control or pressure control

• Processes where even temporary output on/off results in inconvenience

• Processes where a large output change at control element results in inconvenience

• Processes where variations in PV may exceed an allowable range, adversely affect-

ing product quality

■ Troubleshooting When the Controller Fails to Operate Correctly

If your control tasks are not successful, check the preset parameters and controller wiring before concluding the controller to be defective. The following show some examples of troubleshooting you should refer to in order to avoid the possibility of other problems.

4-4

● The controller does not show the correct process variable (PV).

• The UT550/UT520 controllers have a universal input. The type of PV input can be set/changed using the parameter “IN1”. At this point, the controller must be wired correctly according to the selected type of PV input. Check the wiring first if the controller fails to show the correct PV value. To do this, refer to “2. Initial Settings”. With the parameters “RH1”, “RL1”, “DP1”, “SH1” and “SL1”, it is possible to scale the input signal and change its number of decimal places. Also check that these parameters are configured correctly.

● The controller does not provide any control output or the control output does not change at all.

• The UT550/UT520 controllers have a universal output. The type of control output can be set/changed using the parameter “OT1”. At this point, the controller must be wired correctly according to the selected type of control output. Check the wiring first if the controller provides no control output. To do this, refer to “1.5 Terminal Wiring Diagrams”. With the parameters “OH” and “OL”, it is possible to set/change the high and low limits of control output. The control output may not change at all, however, because of restrictions on these parameters. Also check the restrictions on these parameters.

• The control output can only be changed when the controller is in the MAN mode. If the MAN lamp is off (i.e., the controller is in the AUTO mode), you cannot change the control output using key operation.

● The control output does not change soon after the target setpoint SP has been changed.

• If this happens, check the setpoint of the parameter “MOD”. In cases where fixedpoint control is selected as the PID control mode (MOD = 1), tracking based on the Iterm works to prevent the control output from changing suddenly even if the target setpoint SP is varied. The control output therefore may appear to be working incorrectly at first; however it gradually adapts itself to the new target setpoint. Be especially careful when the controller is in the fixed-point control mode; the control output may fail to change and therefore result in a loss of control if you change the target setpoint SP too frequently.

4.2.4 Replacing Parts with a Limited Service Life

The follwing UT550/UT520 parts have a limited service life. The service life given in the table assume that the controller is used under normal operating conditions.

Part Service life

EEPROM About 100,000 times of writings

Alarm output relays About 100,000 more ON-OFF operations or with resistance load

Control output relays About 100,000 more ON-OFF operations or with resistance load

If any of these parts, except control output relays, cause a controller failure due to deterioration, contact your dealer for replacement at your cost. Control output relays can be replaced by yourself.

See Also “4.2.5 Replacing Control Output Relays”, for how to replace the control output

relays.

4.2.5 Replacing Control Output Relays

5.2 Lists of Parameters

This section describes the functions of parameters briefly. In addition, each parameter table has a “User Setting” column, where you can record your setpoints when setting them in the controller.

* Parameters relating to PV or setpoints should all be set in real numbers.

For example, use temperature values to define target setpoints and alarm setpoints for temperature input.

* The “User Setting” column in the table below is provided for the customer to record

setpoints.

* Numbers in ( ) are the parameter setpoints that apply when the communication func-

tion is used. ex. REM (1), LCL (0)

1: Overshoot suppressing function

Suppresses overshoots generated by abrupt changes in the target setpoint or by disturbances.

2: Hunting suppressing function (Stable mode)

Suitable to stabilize the state of control when the load varies greatly, or the target setpoint is changed. Enables to answer the wider characteristic changes compared with Response mode.

3: Hunting suppressing function (Response mode)

Enables quick follow-up and short converging time of PV for the changed target setpoint.

Note: Use "SUPER" function (SC) 2 or 3 in PID control or PI control. "SUPER" function 2 or 3 is not available in the following controls:

1) ON/OFF control

2) P control (control for proportional band only)

3) PD control (control for proportional band and derivative item only)

Pressing the SET/ENT key with valve position set to the fully-closed position causes the adjusted value to be stored. When V.L. adjustment is complete, V.L. stops blinking.

Pressing the SET/ENT key with valve position set to the fully-opened position causes the adjusted value to be stored. When V.H. adjustment is complete, V.H. stops blinking.

■ Tips About Heating/Cooling Control (for heating/cooling controllers only)

In heating/cooling control, the controller outputs the result of computation after splitting it into heating-purpose and cooling-purpose signals. In addition, the controller can perform PID control or ON/OFF control on the heating and cooling sides separately. When performing ON/OFF control, set the proportional band to “0”. The controller splits the result of computation (0 to 100%) into heating-side and coolingside signals, as described below.

• 0% to 50% of the computation result is presented as a 0% to 100% cooling-side output.

• 50% to 100% of the computation result is presented as a 0% to 100% heating-side output.

Precautions in Heating/Cooling Control

• Keep the ratio of the heating-side proportional band (P) to the cooling-side proportional band (Pc) equal to or below 5.

• If neither the heating-side nor the cooling-side is performing ON/OFF control, setting the integral time (I or Ic) of one side to “0” results in the Integral Time parameters of both sides being set to “OFF”, irrespective of the integral time setting of the other side.
