Introduction
Thank you for purchasing the UT350/UT320 digital indicating controller.
The controller is shipped from the factory with 3 hardcopy user's manuals (A2 size) and 1 user's manual on CD-ROM. The
3 user's manuals in hardcopy format describe the operating procedures required for basic use. It is recommended that you
refer to these user's manuals to understand [1] installation, [2] initial settings, and [3] operating procedures of the controller.
The CD-ROM contains an User's Manual (Reference) with descriptions of various functions and setting ranges that can be
set as necessary.
Moreover, the use of an optional parameter setting tool (model: LL100-E10) allows you to easily perform settings and
adjustments with a PC.

1. Safety Precautions
The following symbol is indicated on the controller to ensure safe use.
CAUTION
This symbol on the controller indicates that the operator must refer to an explanation in the user's manual in order
to avoid the risk of injury or death of personnel or damage to the instrument. The manual describes how the operator
should exercise special care to avoid electric shock or other dangers that may result in injury or loss of life.
The following symbols are used in the hardcopy user's manuals and in the user's manual supplied on the CD-ROM.
NOTE
Indicates that operating the hardware or software in a particular manner may damage it or result in a system failure.
IMPORTANT
Draws attention to information that is essential for understanding the operation and/or features of the controller.

3. 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,
(4) temperature can be maintained at about 23°C and the fluctuation is minimal,
(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 150mm away from every side; the panels should be made of either 1.43mm-thick
metal-plated steel plates or 1.6mm-thick 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
Front panel
with the front panel facing upward. Do not install it facing
of controller
downward. The position of right and left sides should be hori-
zontal.

4. How to Connect Wires
CAUTION
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.
2) For the protection and safe use of the controller, be sure to place a circuit breaker (conforms with IEC60947,
Must not
5A, 100V or 220V AC) near the controller where the breaker can easily be operated. In addition, be sure to
exceed 30
indicated that it is the instrument to cut the power supply of the controller.
3) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.

controller
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
Unit: mm
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.
Large bracket
3) Control output relays may be replaced. However, because they have a life of 100,000 times that of the resis-
tance 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.
