These jumpers MUST be connected.

- The load cell excitation voltage of the F701-C is 10V. Heating or breakage may occur unless the load cells maximum excitation voltage is 10V or more.

- When using the F701-C with the four-wire load cell connected, be sure to connect +EXC and +S, and -EXC and -S. Even if +S and -S are not connected, normal operation is performed apparently, but heating or breakage may occur because excessive voltage is applied to the load cell.

CAUTION

2-1-1. 6-wire Connection

The load cell input of the F701-C is a 6-wire (remote sense) connection. 6-wire shielded load cell

cable should be used and kept separate from AC or other noise generating wire.

* Remote sense lines are used to detect and correct variations in excitation voltage over long cable

runs.

2-1-2. 4-wire Connection

Connect 3 and 4, and 5 and 6 as shown below.

Even 4 and 6 on the terminal block are open, normal operation is performed apparently, but heating

When connecting several load cells in parallel, load cell capacity should be higher than

expected load to compensate for mechanical shock or eccentric loading.

The group of “n” parallel load cells

viewed from this device side can be

regarded as a unit load cell the rated

capacity of which is multiplied by “n”

and the sensitivity of which is

unchanged. The averaging resistance (R)

should be 300 to 500Ω, equal in relative

ratio and excellent in temperature

coefficient. No averaging resistance is

needed if load cells with consideration

for parallel connection are used.

Request

2-1-3. Connecting Load cells in Parallel

In some industrial weighing apparatus, two or more load cells may be connected in parallel to form

a hopper scale or track scale. The manner of connection is shown below.

Parallel connection can simply be made by using the optionally available B410 (summing box for

4-point multi load cell).

2-1-4. Sensor Cable

Cable colors of sensors may differ from one manufacturer to another (it may even differ from one

model to another for some products). Refer to the sensor manual (or data sheet) and check signal

names and colors in order to connect the cables correctly.

4) Mount the terminal block cover.

5) Remove the screws(M4) of the protective ground, align the crimp contacts with the

screw holes, and then tighten the screws.

2-3. Connection of the Guard Ground

The grounding terminal is for prevention of electric shocks.

Use an approx. 0.75mm

thick wire, and be sure to ground.

2-4. SI/F Connection

5 to 6mm

- Cable can be from 24 ~ 14AWG (0.2 ~ 2.5mm2).

- It is not necessary to solder the cable wires or to fix a solderless terminal.

- If several cables to be inserted to the same hole, twist those cable wires together and insert.

Request

The SI/F allows connection of up to three nonpolarized external devices.

As for wire materials, use parallel 2-core cables, cabtyre cables, or the like.

Connect to the cage clamp type terminal block by using the attached mini screwdriver.

1) Strip the casing 0.2in (6mm) on the cable to be connected.

Twist the bare wire to fit the terminal hole.

After calibration.....

The F701-C and load cell

function as a weighing device.

4-1. Span Calibration

Calibration is performed for matching the F701-C to a load cell. For example, it is work to adjust so

that the F701-C accurately displays 100.00kg when an actual load (or weight) of 100kg is applied to

the load cell (balance section) of the weighing apparatus to which the F701-C is connected. This

operation is called Span Calibration.

Calibration procedure performed by entering the rated output value (mV/V) and rated capacity

value of load cell without using real load.

Secondary calibration function is provided for provisional calibration when the F701-C develops

trouble or the calibration value is mistakenly changed.

The secondary calibration is only a provisional method. Calibration with actual load must be done

as soon as possible.

Release calibration inhibit LOCK by the switch OFF on the rear

panel.

Release Setting Value LOCK which inhibits the calibration.

The displayed unit is set.

If the registered value exceeds by 9 scale divisions, display shows

over scale, “ ”.

Set the weight value corresponding to the output value to be

entered in *1.

If it is necessary, re-calibrate initial zero point.

Disable changing setting value related to calibration.

Turn the calibration LCOK ON to prohibit the calibration for

avoiding false operation.

4.CALIBRATION

- Set the Balance Weight Value to the Capacity or less.

- For performing calibration at the rated value according to the specifications of

the load cell, set the Capacity to the same value as the rated value of the load

cell.

- When connecting several load cells in parallel, it is possible to occur some

differences between input and output value due to voltage drop caused by

connection or material of lines.

In this case, register actual input value to perform accurate calibration.

6-1. Feeding Weighing and Discharging Weighing

6-1-1. Feeding Weighing

A method controlling a weight while feeding raw materials into a measuring tank (hopper).

Example of feeding weighing

In this example system, raw materials are to be fed from the material tank to the weighing tank. At

first, the feeding valves are to be fully opened to feed, and closed in the order of Set Point 1 → Set

Point 2, and Set Point 2 → Set Point 3 at the time of Final - Set Point 1, and Final - Set Point 2,

respectively. The feeding valves are to be completely closed at the time of Final - Compensation.

The weighed raw materials are to be discharged to a container by opening the discharge valves.

6.DISCHARGING CONTROL MODE

TARE

The feeding valves and discharge valves should be opened and closed through

the sequencer or relay sequence according to the control signals from the

F701-C.

(1) By setting external input Tare subtraction ON (or with the key on the panel), Net

weight is zeroed. (Tare subtraction)

(2) The feeding valves are fully opened to start feeding. When the weighed value reaches (Final -

Set Point 1), Set Point 1 output signal turns ON. (If the comparison inhibit timer is set, the timer

starts.) Set Point 1 valve of the material tank is closed.

(3) When the weighed value reaches (Final - Set Point 2), Set Point 2 output signal turns ON. (If the

comparison inhibit timer is set, the timer starts.) Set Point 2 valve of the material tank is

closed”.

(4) When the weighed value reaches (Final - Compensation), Set Point 3 output signal turns ON,

and if the judging timer is set, the timer starts. The feeding valves are completely closed.

(5) After the judging timer expires, Over/Under judgment is made. If the weighed value exceeds the

range of the Over/Under setting value, the over signal or under signal turns ON.

(6) Raw materials are discharged from the weighing tank to a container. The valves of the weighing

tank should be opened. Completion of discharge is confirmed with the Near Zero signal. In

First supply raw material into a metering tank (hopper), then controls a weight while discharging

raw material from the metering tank.

Example of discharging weighing

In discharging weighing, the amount of discharge can be weighed by adding negative weighed

values. In this example system, raw materials are to be fed from the material tank to the weighing

tank, and a fixed quantity of raw materials are to be discharged from the weighing tank to a

container. At first, the discharge valves of the weighing tank are to be fully opened to discharge raw

materials, and the discharge valves are to be closed in the order of Set Point 1 → Set Point 2, and

Set Point 2 → Set Point 3 at the time of Final - Set Point 1, and Final - Set Point 2, respectively. The

discharge valves are to be completely closed at the time of Final - Compensation, when one

measurement is completed. When the weighing tank runs short, the feeding valves are to be opened

to replenish the weighing tank with raw materials from the material tank to weigh.

6.DISCHARGING CONTROL MODE

TARE

The feeding valves and discharge valves should be opened and closed through

the sequencer or relay sequence according to the control signals from the

F701-C.

(1) The valves of the material tank are opened by the lower limit signal, and raw materials are

fed into the weighing tank.

(2) It is detected by the upper limit signal that the weighing tank is full, and the valves of the mate-

rial tank are closed.

(3) By setting external input Tare subtraction ON (or with the key on the panel), Net

weight is zeroed. (Tare subtraction)

(4) The discharge valves are fully opened to start discharging. When the weighed value reaches

(Final - Set Point 1), Set Point 1 output signal turns ON. (If the comparison inhibit timer is set,

the timer starts.) The discharge valve (Set Point 1) is closed.

(5) When the weighed value reaches (Final - Set Point 2), Set Point 2 output signal turns ON. (If the

comparison inhibit timer is set, the timer starts.) The discharge valve (Set Point 2) is closed.

(6) When the weighed value reaches (Final - Compensation), Set Point 3 output signal turns ON,

and if the judging timer is set, the timer starts. The discharge valves are completely closed.

(7) After the judging timer expires, Over/Under judgment is made. If the weighed value exceeds the

range of the Over/Under setting value, the over signal or under signal is output. In weighing

from the second time onward, (3) ~ (6) are repeated in a like manner.

(8) When the weighing tank runs short of raw materials, the valves of the material tank are opened

by the output of the lower limit signal to feed raw materials into the weighing tank.

all the signals of Set Point 1 output, Set Point 2 output and Set Point 3 output are turned OFF.

● If the start signal is turned ON when the stop signal is ON, it will become a sequence error

( ) and will not start the weighing.

6-3. Auto Free Fall Compensation Regulation /

(D1＋ D2＋ D3・・・・・・DA)

×　C

Value added to Compensation value

The auto free fall compensation function stores compensation samples by

using the Over/Under judgment signals.

If the number of Judging Times is set to 00 (no judgment), the F701-C cannot

store such samples for auto free fall compensation, so that the compensation

function does not work.

For using the auto free fall compensation function, set the number of Judging

Times to 01 or more.

For details, please refer to "a) Judging Times" on P.96.

Request

Auto Free Fall Compensation ON/OFF / Average Count of Auto Free Fall Compensation / Auto Free Fall Compensation Coefficient

Auto free fall compensation adjusts the amount of suspended ingredient automatically to reduce

weight error. Register auto free fall compensation parameter.

Principle of auto free fall compensation

Sampling the weight value when the complete signal turns ON after Set Point 3 finished.

Record “n” times(A) the difference(D) between set Final value and actual weight value, average the

difference and multiplied by compensation coefficient, then add the result of Compensation value.

6.DISCHARGING CONTROL MODE

F701-C can regulate the value of D for minimizing the errors.

When D is within the range of (Final + AFFC.) ≧ Actual weight ≧ (Final - AFFC.), F701-C

processes auto free fall compensation.

And when compensation feeding is ON in Sequence Mode, F701-C samples the weight value

before compensation feeding.

Setting compensation coefficient

Compensation coefficient can be selected from 1/4, 2/4, 3/4, or 1.

You can get more accurate compensation value by selecting 1 when each

weight value is approximate same in each measuring or by selecting 1/4 ~ 2/4

when each weight value fluctuates in each measuring.

Example) Final 20.000
