1. no one may accidentally touch the terminals,

2. mechanical vibrations are minimal,

3. corrosive gas is minimal,

150 mm

1-2

4. temperature can be maintained at about 23C and the fluctuation is minimal,

150 mm150 mm

150 mm

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 150 mm away from every side; the panels should be made of either 1.43 mm-thick metal-plated steel plates or 1.6 mmthick 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.

Direction to insert the controller

Insert the controller into the opening at the front of the panel.

Insert a screwdriver into the brackets to tighten the screws.

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.

This chapter describes examples of setting PV input types, control output types, and alarm types. Carrying out settings described herein allows you to perform basic control. Refer to examples of various settings to understand how to set parameters required. Refer to “5.1 Parameter Map” for an easy to understand explanation of setting various parameters. If you cannot remember how to carry out an operation during setting, press the display (operating display) that appears at power-on.

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.

2.2 Setting PV Input T ype (Setting First at Power-on)

NOTE

• The controller displays the operating display when the power is turned on. However, if PV input type has not been set, “IN” appears. In this case, first use the display the input range code to use, then press the the maximum value (RH) and minimum value (RL) of the PV input range (for voltage input, set the maximum value (SH) and minimum value (SL) of the PV input scale). See the operating procedure below for more details.

• The controller is configured to the initial value of each parameter at the factory before shipment. First check the initial values shown in “5.2 Lists of Parameters,” and change parameter values as necessary .
