GENERAL

The FA5A/FA5V is a compact, front terminal connection type

distributor with square root extractor, is used in combination with

a two-wire transmitter to convert the differential pressure flow

signal into a linearized signal proportional to the ow.

Low cut point setting, zero/span adjustment, and I/O monitoring

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

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

M4 screw terminals are provided for the connection of external

signals. Attach a crimp-on lug to each wire for connection to the

terminals.

●Recommended cables: A nominal cross-sectional area of 0.5

mm2 or thicker for signal cables, and that of 1.25 mm2 or thicker

for power cables.

Connection of Setting Tools

NOTE

●Do not connect anything to the terminals that are not

used in the wiring diagram. Otherwise it may cause

the malfunction or damage.

●The power line and input/output signal lines should

be installed away from noise-generating sources.

Otherwise accuracy cannot be guaranteed.

●Adhere strictly to the specications to avoid

overheating or damage. Before turning on the power,

ensure the following:

(a) Power supply voltage and input signal value

applied to the product should meet the required

specications.

(b) The external wiring to the terminals are as

specications.

●Do not operate the product in the presence of

ammable or explosive gases or vapors.

●The product is sensitive to static electricity; exercise

care in handling. Before you operate the product,

touch a nearby metal part to discharge static

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, DMM (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)

6.2 Calibration Procedure

1. Connect the instruments as shown below.

(4) Input the value equivalent to 100% value of the input

range to the distributor.

(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 the indicating value of DMM deviates to the (+) side,

set (−) value equivalent to deviation; if it deviates to the (−)

side, set (+) value equivalent to deviation for adjusting the

output value to 0%.

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

operation as the above in [C02: OUT100%]

For adjustment using a setting tool, refer to the User’s Manual for

each setting tool and “5. List of Parameters” in this manual.

Use the VJ77 of version R1.05 or later.

User’s Manual for the VJ77 [Document No.: IM 77J01J77-01E]

User’s Manual for the JHT200 [Document No.: IM JF81-02E]

2 Use the vol tage current so urce and appl y current signals

equivalent to 0, 6.25, 25, 56.25, and 100% of the input range to

the distributor.

3. 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.

Input Adjustment Procedure

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

to the distributor.

(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.

•Adjust so that the indicated value and measured value

of [C04: ZERO ADJ] become equal.

INC: Increase (Adjusts the increased value of the input

value)

DEC: Decrease (Adjusts the decreased value of the

input value)

RST: Reset of the adjustment value
