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
A setting tool for adjustment (Refer to "4. Setting Parameters" in this manual.

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. User’s Manual for VJ77 [Document No.: IM 77J01J77-01E];
however, use the VJ77 of version R1.05 or later.
