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.

NOTE

Never touch the opening at the bottom of the case. It is to be used in the factory at shipping.

● 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

1.3 How to Connect Wires

1) Before carrying out wiring, turn of f 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 R TD 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.

1. Before attaching the terminal cover, bend the side with the groove inward as shown in Fig. A. Be careful not to bend it backwards. This not only marks it harder to attach the cover but will also weaken its hold.

2. Fit the holes on the top and bottom of the terminal cover the projections on the brackets (Fig. B) and lock in place. The figure right shows the attachment of a terminal cover to UT controller .

• 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).

• 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 .
