NOTE

To install the controller, select a location where:

1. No-one may accidentally touch the terminals; 6. There are no resulting magnetic disturbances;

2. Mechanical vibrations are minimal; 7. The terminal board (reference junction compen-

3. Corrosive gas is minimal; sation element, etc.) is protected from wind;

4. The temperature can be maintained at about 23°C with 8. There is no splashing of water; and

minimal fluctuation; 9. There are no flammable materials.

5. There is no direct heat radiation;

Never place the controller directly on flammable items.

If the controller has to be installed close to flammable items or equipment, be sure to enclose the controller in shielding panels positioned at least 150mm away from each side. These panels should be made of either 1.43mm thick metal-plated steel plates or 1.6mm thick uncoated steel plates.

● Mount the controller at an angle within 30° from horizontal with

the screen facing upward. Do not mount it facing downward.

30° (MAX)

150mm

NOTE

Splash-proof construction is not available when the side-by-side close mounting method shown in the above figures, is chosen for any of the controllers.

■ Mounting the Controller

[ How to remove the bracket ] To move the bracket, push down the center of the upper and lower parts of the controller softly. The bracket is released from the latch.

Push the bracket to the panel, and then secure the bracket into position.

Direction for mounting

Insert the controller into the opening with the terminal board facing the front. Set and tighten the top and bottom brackets on the controller to fix it on the panel.

5. Wiring

1) Before you start wiring, turn off the power source and use a tester to check that the controller and cables are not receiving any power in order to prevent electric shock.

2) For safety, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC60947) near the instrument so as to be operated easily, and clearly indicate that the device is used to deenergize the instrument.

3) Wiring should be carried out by personnel with appropriate electrical knowledge and experience.

1) Use a single-phase power source. If the source has a lot of noise, use an isolation transformer for the primary

side and a line filter (we recommend TDK’s ZAC2205-00U product) for the secondary side. When this noise-prevention measure is taken, keep the primary and secondary power cables well apart. Since the controller has no fuse, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC standards) and clearly indicate that the device is used to de-energize the controller.

7mm or less

2) For thermocouple input, use shielded compensating lead wires. For RTD input, use shielded wires which have low resistance and no resistance difference between the 3 wires. See the table given later for the specifications of the cables and terminals and the recommended products.

3) The control output relay cannot be replaced even though it has a limited service life (100,000 relay contacts

Always fix a terminal cover bracket to the UT150 controller before wiring if an optional anti-electric-shock terminal cover (part number: L4000FB) is used.

IMPORTANT

for the resistance load). Thus, an auxiliary relay should be used so that the load can be turned on and off.

When using an inductive load (L) such as an auxiliary relay and solenoid valve, be sure to insert a CR filter (for AC) or diode (for DC) in parallel as a spark-rejecting surge suppressor to prevent malfunctions or damage to the relay.

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