COMPONENT IDENTIFICATION

■ FRONT PANEL CONFIGURATIONS

INSTALLATION

Pull out the body in pressing the clamps located at the top and
bottom of the unit to separate it from the base socket.

■ DIN RAIL MOUNTING

Set the base socket so that its
DIN rail adapter is at the bot­tom. Hung the upper hook at
the rear side of base socket on
the DIN rail and push in the
lower. When removing the
socket, push down the DIN
rail adapter utilizing a minus
screwdriver and pull.

POINTS OF CAUTION

■ POWER INPUT RATINGS

• Power input ratings are specified by the model number
suffix code. Check the power input voltage for the unit on the
specification label.

85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 4.5VA
170 – 264V AC rating: 170 – 264V, 47 – 66 Hz, approx. 4.5VA
24V DC rating: 24 V ±10%, approx. 70mA
110V DC rating: 85 – 150V, approx. 20mA

■ REMOVING THE UNIT

• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.

■ ENVIRONMENT

• Indoor use

• When heavy dust or metal particles are present in the air,
install the unit inside proper housing with sufficient ventila­tion.

• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -5 to +55°C (23
to 131°F) with relative humidity within 30 to 90% RH in
order to ensure adequate life span and operation.

■ WIRING

• Do not install cables (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).

• Do not bind the unit's cables together with other cables
where high noise levels are present. Do not install them in
the same duct.

■ AND ....

• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.

CHECKING

1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.

2) Power input voltage: Check voltage across the terminal 7
–8 with a multimeter.

3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
(With 20°C or 68°F, approx. 220mV with Pt 100Ω, approx.
110mV with Pt 50Ω.)
If RTD wires are broken, the output goes over 100% (below
0% with downscale protection) due to burnout protection
function. Check leadwires in such a case.

4) Output: Check that the load resistance meets the de­scribed specifications.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibra­tion, unless you need to match the signal to a receiving
instrument or conduct regular calibration.
Zero and span are adjusted with using the Programming
Unit (model: PU-2

❑).

Refer to the Operation Manual for Model PU-2

❑ for explana-

tions how to use the programmer.

■ WARNING ON USE OF THE PROGRAMMING UNIT

• Be sure to disconnect the Programming Unit before you

turn on/off power supply to the unit.

■ HOW TO CALIBRATE THE OUTPUT SIGNAL

Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.

• Fine Output Calibration

Using the Programming Unit (ITEM 19, 20)

ITEM 19 is for Zero, and ITEM 20 is for Span.

1) Turn the unit into Program mode (ITEM 01).

2) Apply simulated 0% input. Increase/decrease values (de­fault: 0%) at ITEM 19 until the output signal is calibrated
to actual 0%.

3) Apply simulated 100% input. Increase/decrease value
(default: 100%) at ITEM 20 until the output signal is
calibrated to actual 100%.

4) Apply simulated 0% input again and check 0% output.

5) When 0% value is changed, repeat the above procedure 2)

- 4).
The 0% value may be shifted when the output span is
greater than the input span (gain ≥1).

MAINTENANCE

Regular calibration procedure is explained below:

■ CALIBRATION

Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu­racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the "ADJUST­MENT PROCEDURE" explained earlier.
