1.2 How to Install

NOTE

To install the controller, select a location where:

1. no one may accidentally touch the terminals,

2. mechanical vibrations are minimal,

3. corrosive gas is minimal,

150mm

1-2

4. temperature can be maintained at about 23C and

the fluctuation is minimal,

150mm150mm

150mm

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.

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.

: 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 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.

Displays trend, valve opening or a parameter. Displays

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 second allows you to switch between the operating display and the main menu for operating parameter setting display alternately.

Used to switch between displays. Pressing this key while any operating display is shown lets you switch to another prearranged operating display. Pressing this key while any display other than an operating display is shown lets you go back one display. (One to four presses (maximum) of this key lets you return to the current operating display, though the number of presses depends on the operating status.)

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. These keys also switch between menu displays when a main menu or submenu of parameter setting display is shown.

In this case, set a UT mode to “Cascade Control,” following the operating procedure described below. Then, set PV input type, control output type and others.

• The controller is configured to the default of each parameter at the factory before shipment. First check these defaults listed in “5.2 Lists of Parameters” and change their values if necessary.
