■ 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.

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.

1-5

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.

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

Function

When lit, indicates the status of a deviation (PV - SP).

: Is lit (in orange) if a deviation exceeds the deviation display range. : Is lit (in green) when a deviation is within the deviation display range. : Is lit (in orange) if a deviation falls below the deviation display range.

The deviation display range can be changed using the setup parameter “DVB”.

The deviation monitor goes off if any display other than the operating display or SELECT display is shown. Is lit (in green) to indicate the status of operation or control. REM: Is lit when in remote mode. MAN: Is lit when in manual mode. The lamp blinks when the controller is being auto-tuned.

Interface for an adapter cable used when setting and storing parameters from a PC. This requires an optional parameter setting tool.

Displays PV. Displays a menu symbol when you set a parameter. Displays an error code (in red) if an error occurs.

Displays a parameter symbol in 3-digit LED. Displays the setpoint of a parameter in 5-digit LED.

UT450: If any of alarms 1 to 4 occurs, the respective alarm indicator lamp (AL1 to AL4) is lit (in orange). UT420: If any of alarms 1 to 3 occurs, the respective alarm indicator lamp (AL1 to AL3) is lit (in orange).

Used to switch between the AUTO and MAN modes. Each time you press the key, it switches to the AUTO or MAN mode alternately.

Used to switch or register a parameter. Pressing the key for more than 3 seconds allows you to switch between the operating display and the main menu for operating parameter setting display alternately.

Used to change numerical values. On setting displays for various parameters, you can change target setpoints, parameters, and output values (in manual operation). Pressing the key decreases a numerical value, while pressing the key causes it to increase. You can hold down a key to gradually increase the speed of change. To change from the parameter setting (operating or setup) display to the menu or from the setup parameter setting display menu to operating parameter setting display menu, press the and keys simultaneously.

2.8 Description of Multiple Setpoints and PID

The UT450/UT420 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.

Note: In factory-shipped settings, up to four target setpoints are available. To use five or

more target setpoints, use setup parameter “GRP” (PID group number) to set the number of setpoints to use.

Low limit of alarm setpoint

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.

3. Operations

This chapter describes key entries for operating the controller . For operations using external contact inputs, see “1.5 T erminal Wiring Diagrams.” If you cannot remem- ber how to carry out an operation during setting, press the seconds. This brings you to the display (operating display) that appears at poweron.

3.1 Monitoring-purpose Operating Displays A vailable 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. One group is operating displays for standard and position proportional controllers and the other group is operating displays for a heating/cooling controller.

3.3 Performing/Canceling Auto-tuning

Auto-tuning should be carried out after setting a target setpoint (SP). Make sure the controller is in automatic operation mode (AUTO) and in running state (RUN) before carrying out auto-tuning. 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

key with the heating-side output under manipulation (i.e., coolingside output C = 0.0%), the heating-side output (H =) decreases. Consequently , both the heating-side and cooling-side outputs change to 0.0%. If you keep the

key held down longer, you enter the state of manipulating the cooling-side output, and its value begins to increase.

Inversely , if you hold down the

key with the cooling-side output under manipulation (i.e., heating-side output H = 0.0%), the cooling-side output (C =) decreases. Consequently , both the heating-side and cooling-side outputs go to 0.0%. If you keep the

key held down longer, you enter the state of manipulating the heating-side output, and its value begins to increase.

■ Remedies if Power Failure Occurs during Operations

The operation status and remedies after a power failure differ with the length of power failure time:

● Instantaneous Power Failure of 20 ms or less

A power failure is not detected. Normal operation continues.

● Power Failure of about 2 seconds or less

The following show effects caused in “settings” and “operation status.”

Alarm action Continues. Alarm with standby function will enter standby status. Setting parameter Set contents of each parameter are retained. Auto-tuning Cancelled. Control action Action before power failure continues.

IM 05D01C12-41E 2nd Edition : Sep.20,2002-00

● Power Failure of more than about 2 seconds

The following show effects caused in “settings” and “operation status.”

Alarm action Continues. Alarm with standby function will enter standby status. Setting parameter Auto-tuning Cancelled. Control action Differs with setting of setup parameter “R.MD” (restart mode).

Set contents of each parameter are retained.

For heating/cooling control, preset output value is 50% of PID computation.

Outputs preset output value (PO) as control output and continues action set before power failure in MAN mode. Outputs preset output value (PO) as control output and continues action set before power failure in AUTO mode.

■ T roubleshooting 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.

● The Controller does not Show the Correct Measured Input (PV).

4-4

• The UT420/UT450 controllers have a universal input. The type of PV input can be set/changed using the parameter “IN”. 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 “RH”, “RL”, “DP”, “SH” and “SL”, 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 UT450/UT420 controllers have a universal output. The type of control output can be set/changed using the parameter “OT”. 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 T arget Setpoint (SP)

has been Changed.

• If this happens, check the setpoint of the parameter “MOD”. In cases where fixed-point control is selected as the PID control mode (MOD = 1), tracking based on the I-term 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.

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 is provided for the customer to record setpoints. * The column “Target Item in CD-ROM” in the table provides references from User’s

Manual (Reference) (CD-ROM Version) which describes items in more detail and

items that are not contained in this manual. * Numbers in ( ) are the parameter setpoints that apply when the communication func-

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