1.2 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,

150 mm

1-2

4. temperature can be maintained at about 23C and the fluctuation is minimal,

150 mm150 mm

150 mm

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 pro-

vide shielding panels all around the indicator, 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 mm-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

Turn off the power to the indicator 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 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 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 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.

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) Alarm output relays 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.

2.2 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 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 indicator 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.

■ 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 standby feature temporarily return to their stand-by state, however.)

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

This section describes the cleaning and maintenance of the UM351/UM331.

4.2.1 Cleaning

The front panel and operation keys should be gently wiped with a dry cloth.

NOTE

Do not use alcohol, benzine, or any other solvents.

4.2.2 Replacing Brackets

When the brackets are broken or lost, purchase the following brackets for replacement.

■ Attaching Terminal Cover

The procedure for attaching the terminal cover is as follows.

Do not touch the terminals on the rear panel when power is being supplied to the indicator. Doing so may result in electric shock.

4-5

CAUTION

Before attaching the terminal cover, turn off the source circuit breaker and use a tester to check that the power cable is not conducting any electricity.

Before attaching the terminal cover, fold it once or twice so that the side which has the “Handle With Care” symbol ( ), is on the outside.

Fold over.

Fold over.

Folding Direction of Terminal Cover

Alert symbol on the back

NOTE

Do not fold the terminal cover the wrong way, doing so not only reduces the cover’s strength but may also cause the hinge to crack, thereby disabling attachment.

With the cover properly folded, fit its top and bottom holes to the protrusions of the

mounting brackets.

Fit the hole of the terminal cover to the protrusion on the mounting bracket.

■ Functions of Active Color PV Display

This part describes the functions of “Active Color PV Display.” PV display color is changed by the following four actions.

PV display is selectable from red-to-green or green-to-red changing action, or fixed color. Link to alarm 1 mode (when PCMD = 2, 3) (Setting example-1) Link to alarm 1 and 2 mode (when PCMD = 4, 5) is the same. When either of the alarms

occurs, the display color is changed. PV limit mode (when PCMD = 6, 7) (Setting example-2) Fixed color mode (when PCMD = 0, 1) (Setting example-3)

Setting Example-1 : Link to Alarm

Works linked to alarm 1. Set “PV high limit alarm” for alarm 1 type, and “80°C” for alarm 1 setpoint. If PCMD (PV color mode parameter) = 2, PV display color is changed from green to red when PV input value exceeds alarm 1 setpoint. The red-to-green changing action is selectable. Setting parameters PCMD (PV color mode parameter) = 2 AL1 (Alarm 1 type parameter) = 1 A1 (Alarm 1 setpoint parameter) = 80°C HY1 (Alarm 1 hysteresis parameter) = 5°C

Setting Example-2 : Link to PV

Set high limit “70°C” for PCCH, and low limit “20°C” for PCCL. PV display color is changed from green to red when PV input value is out of the range. The red-to-green changing action is selectable. Setting parameters PCMD (PV color mode parameter) = 6 PCCH (High limit for PV color change parameter) = 70°C PCCL (Low limit for PV color change parameter) = 20°C Hysteresis fixed to 0.25% is inserted where PV display color is changed.

■ External RJC

External RJC is not a compensation function built in a indicator but a compensation function working outside the indicator.

External RJC is used when input is thermocouple, and RJC=OFF. Using External RJC makes the accuracy of RJC higher and shortens the compensating

wire.
