3. How to Install

NOTE

To install the indicator, 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 indicator directly on flammable items or equipment.
If the indicator has to be installed close to flammable items or equipment, be sure to provide shielding panels all
around the indicator, 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 indicator 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

CAUTION

Turn off the power to the indicator before installing it on the panel because there is a possibility of electric shock.

Recommended
tightening torque
:0.4 N•m

After opening the mounting hole on the
panel, follow the procedures below to in­stall the indicator:

1. Insert the indicator 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 indicator as shown in the
figure on the left, then tighten the screws
of the brackets. Take care not to over­tighten them.

4. How to Connect Wires

CAUTION

1) Before carrying out wiring, turn off the po wer to the indicator 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 indicator, be sure to place a circuit breaker (conforms with IEC60947,
5A, 100V or 220V AC) near the indicator where the breaker can easily be operated. In addition, be sure to
indicate that it is the instrument to cut the power supply of the indicator.

3) Wiring must be carried out by personnel who have basic electrical knowledge and practical experience.

1) Provide po wer from a single-phase instrument power supply . If there is a lot of noise in the po wer 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.

3) Alarm output relays ha ve 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 sur ge, 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 makes it harder to
attach the cover but will also weaken its hold.

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

IMPORTANT

The indicator automatically returns to the display at the time of power-on (i.e., Operating display) if no key is
operated for at least one minute.

2. Setting PV Input Type (Setting First at Power-on)

NOTE

• The indicator 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 key to

display the input range code to use, then press the
to register it. Then, set 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 indicator is configured to the initial value of each param­eter at the factory before shipment.
First check the initial values shown in 2. Lists of Parameters, in
parameter values as necessary.

The indicator may automatically initialize the registered operating parameter setpoints if any change is made to the
data item PV Input T ype (IN), Maximum Value of PV Input Range (RH), Minimum Value of PV Input Range (RL),
PV Input Decimal Point Position (SDP), Maximum Value of PV Input Scale (SH) or Minimum Value of PV Input
Scale (SL). After a change has been made to any of these data items, be sure to verify the registered operating
parameter setpoints to ensure that they are correct. If any data item has been changed to its default, set it to a
required value.

The following operating procedure describes an example of changing
alarm-1 (factory-set value: PV high limit alarm) to PV low limit alarm.
When you have changed alarm type, the alarm setpoint will be initial­ized; set the alarm setpoint again.

■ If a Power Failure Occurs during Operation

● Momentary power failures shorter than 20 ms

The indicator is not affected at all and continues normal operation.

● Momentary power failures of 20 ms or longer

• The alarm function of the indicator continues to work normally. (Alarms with the stand-by feature temporarily return to
their stand-by state, however.)

• Setting parameters that have already been configured retain their settings.

Changing the registered value of a setup parameter
