User’s Manual (this manual : IM 77J08T05-01E)

GENERAL

The FT5A/FT5V is a free range type thermocouple converter that

is connected to an IEC/JIS-standard thermocouple (TC), such as

a Type K, T, E, J, R, S, B or N thermocouple to convert tempera-

ture signals into isolated

DC current or DC voltage signals.

Selection of input type (sensor type), temperature unit (°C, K), I/

O range setting, burnout setting, output adjustment, RJC on/off

and I/O monitoring can be made using the optional Parameter

Setting Tool (VJ77) or Handy Terminal (JHT200).

2. INSTALLATION LOCATION

Avoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents,

direct sunlight, radiation, a strong electric eld, and/or a strong
magnetic eld, altitude of more than 2000m above sea level.

If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both this

converter and a eld-installed device.

Operating temperature/humidity range: 0 to 50C/5 to 90%RH
(no condensation)

3. EXTERNAL WIRING

WARNING

Be sure to turn OFF the power supply before wiring to
avoid the risk of electric shock. Use a tester or similar
device to ensure that no power is being supplied to a
cable to be connected.

6. MAINTENANCE

The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it

meets the specied performance.

6.1 Calibration Apparatus

A voltage current source (Yokogawa 7651 or equivalent)
A digital multimeter (Yokogawa 7561 or equivalent)

A precision resistor of 250 Ω ±0.01%, 1W

2. Turn off the RJC using the setting tool.

3. Use the voltage current source and apply the electromotive
force equivalent to 0, 25, 50, 75, and 100% of the measuring
range to the converter.

4. Verify that the corresponding output voltages are 0, 25, 50, 75,

and 100% respectively and within the specied accuracy rating.

(Ro is used for current output.)
Use the setting tool (VJ77 Parameter Setting Tool or JHT200
Handy Terminal) to adjust the input/output signals.

Turning the RJC on/off

(1) Read the parameter [C08: RJC].
(2) Select "ON" or "OFF" in the parameter

[C08: RJC].

NOTE

The RJC returns to "ON" after the power is turned off

and then on again.

Input Adjustment Procedure

(1) Input the value equivalent to 0% value of the input range

to the converter.

(2) Read the parameter

[C04: ZERO ADJ] and check the

input value.

(3) Select “INC” or “DEC” in the parameter

[C04: ZERO

ADJ] to adjust.

INC: Increase (Adjusts the increased value of the input

[voltage] value)

DEC: Decrease (Adjusts the decreased value of the

input [voltage] value)
RST: Reset of the adjustment value
(4) Input the value equivalent to 100% value of the input

range to the converter.
(5) Read the parameter

[C05: SPAN ADJ] and check the

input value.
(6) Adjust the span in the same way as (3).

Output Adjustment Procedure

When adjusting 0% value of output:
(1) Set the adjustment value 0% in the parameter [C01:

OUT 0%].

•The value equivalent to 0% of the output range will be

output, irrespective of the input.
(2) Check the output value via digital multimeter, and adjust

it in the parameter [C01: OUT 0%].

•If it slips out to the (+) side, set (−) value equivalent

to slipout; if it slips out to the (−) side, set (+) value

equivalent to slipout for adjusting the output value to

0%.
*: The 100% value of output can be adjusted by the same

operation as the above in [C02: OUT 100%].

Wire Resistance Compensation

(1) Short-circuit at the sensing end of the eld side.

FT5A
FT5V

Short-circuit at the cable end

(2) Read the parameter [C04: ZERO ADJ] and make sure

the setting is "RESET".
(If the set ti ng is " EXECU TE, sel ect "RE SET". The

compensation value will be reset.)
(3) If "EXEC UTE " i s s ele cte d in the pa ram eter

[C 03:

WIRING R], the wire resistance compensation will be

done automatically.

For adjustment using a setting tool, refer to the User’s Manual for
each setting tool and “5. List of Parameters” in this manual.
