Caution on installation

WARNING

● Use at a proper power supply voltage.

● Do not damage the power cord. Doing so may cause fire or electric shocks.

● Do not touch any terminal while applying power. Doing so may cause electric shocks or

malfunctions.

● If the cover of the main body is opened, it may cause an electric shock internally. Even if the

power is off, the internal capacitor is charged. Contact us for internal inspection or repair.

● In the case of smoke, an abnormal smell or strange sound, immediately turn off the power,

and disconnect the power cable.

● As for the batteries used in F372A, do not at any time dismantle the batteries, change the

batteries shape by subjecting it to pressure or throw the batteries into fires as these may

cause the batteries to explode, catch fire or leak.

CAUTION

● Use the F372A as it is incorporated in a control panel, etc.

● Do not install in the following environments:

- Locations where temperature or humidity exceeds specifications;

- Locations subjected to drastic temperature fluctuations or icing and condensing;

- Outdoors or locations above 2,000m;

- Locations exposed to direct sunlight;

- Locations subject to dust accumulation;

- Locations with poor ventilation;

- Locations with a lot of salt and metal powder;

- Locations where the main unit is subject to direct vibration and shock.

● Take adequate shielding measures when using at the following locations.

- Near a power line.

- Where a strong electric field or magnetic field is formed.

- Where static electricity, relay noise or the like is generated.

● Install the F372A as far away from devices generating high frequency, high voltage, large

current, surge, etc., as possible. Also, carry out wiring separately from their power lines. Do

not carry out parallel wiring and common wiring.

● Do not use it, broken down.

CAUTION

CAUTION

● Tighten the screws for the signal input/output terminals at the specified torque.

If they are loose, shorts, fire or malfunctions may occur.

Tightening torque: 0.5N• m

● For sensors, external inputs/outputs, RS-232C and options, use shielded cables.

● The temporary overvoltage applied to the power should not exceed 1500V.

● Set the correct Excitation Voltage for the sensor. (2.5V is set when F372A is dispatched

from us.)

● For turning on/off the power, be sure to keep intervals of 5 seconds or more.

● After power-on, make sure to warm up the F372A for at least 30 minutes or more before use.

● If the F372A is not used by the specified method, its protective performance may be

impaired.

● Maintenance

- When performing maintenance, disconnect the power.

- Do not wipe with a wet rag, or with benzine, thinner, alcohol, etc. Doing so may cause

discoloration or deformation of the F372A. In the case of heavy contamination, wipe off

the contamination with a cloth after dipping it into a diluted neutral detergent and wringing

it well, and then wipe with a soft, dry cloth.

● When the F372A is shipped, spacers made of corrugated cardboard are used as cushioning

materials.

Though it is factory-designed so that shocks can sufficiently be absorbed, breakage may

result if shocks are applied when the spacers are reused for transportation. If you send the F372A to us for repair, etc., take adequate measures against shocks by using polyurethane

materials, etc., separately.

● If you dispose of the product, handle it as industrial waste.

● Remove the lithium batteries used in the F372A and make sure to dispose them according

INSTALLATION & CONNECTION

2-1. Installation

To install the F372A into a control panel, use the following procedure.

1. Make a hole in the panel according

to the panel-cut dimensions.

2. Remove the screws (two), and

remove the guide rails from both

sides.

* Do not use other screws than

those installed to the F372A body.

3. Fit in the F372A from the front of

the panel.

4. Install from the rear the guide rails

having been removed from both

sides in Step 2, and fix them with

the screws (two).

2-2. Connection

Red screw

Within 6mm

CAUTION

Be aware that the voltage drops depending on the wire thickness and length.

Also, never input an AC power source. Doing so will cause a failure.

Protective

ground

■Power input connection

Connect the positive (+) side of the power source to

the red screw side of the terminal block on the back

of the F372A, and its negative (-) side to the black

screw side. The input voltage is 24V DC(±15%).

■Protective Ground Connection

2　INSTALLATION & CONNECTION

Chapter

The grounding terminal is for prevention of electric shocks.

Use an approx. 0.75mm

thick wire, and be sure to ground.

1. Make sure that no power is applied.

2. Remove the screws(M4) at the protective

ground.

3. Align the solderless terminals(M4) with the

screw holes, and then tighten the screws.

WARNING

- Connect with no power applied because it may cause an electric shock.

- Since the F372A has no power switch, install a breaker.

INSTALLATION & CONNECTION

- Be sure to ground the protective ground terminal to prevent electric shocks.

Do not use other screws than that attached to the main body.

About calibration

Calibration is performed for matching the F372A to a strain-gage sensor. The following two types

of calibration are available for the F372A.

● Equivalent input calibration

Calibration is performed without an actual load by entering the rated output value (mV/V) and

the capacity (to be indicated) of the strain-gage sensor by the keys. Calibration is easily

performed when no actual load is available.

For example, the gain is automatically determined by entering:

CALIBRATION

2.001mV/V (rated output) - 100.0kg (capacity)

● Actual load calibration

Apply an actual load to the strain-gage sensor and enter the actual load value by the keys for

calibration. Calibration is accurately performed with reductions in errors.

Hysteresis setting value is common to all HI limit value.

How to set

5　SETTING OF FUNCTIONS

■Hysteresis

The hysteresis value may be determined so as to allow a margin for timing the turning off of the HI-

LO limit comparison. Normally, it is turned on when the indicated value exceeds the HI limit and is

turned off when the indicated value falls below it. However, by setting the hysteresis, it is turned off

when the indicated value falls below the HI limit further lowered by the hysteresis value.

This function is effective to prevent chattering in such a case where signals fluctuate (vibrate)

subtly.

SETTING OF FUNCTIONS

How to set

■Hold setting　--- Relative (Maximum / Minimum / Difference) ---

If you select the relative maximum and relative minimum hold in the hold function setting, set the relative maximum and relative minimum value detection parameters "relative minimum count" and "relative magnification". Set referring to the principle of operation only when the value cannot be held successfully with the factory settings or when further adjustments are required.

Detection of relative values

The logic of detecting the relative values is given below.

First, when difference X between point A and point B

is larger than the minimum count, point A is judged to

be the relative maximum value and point B is judged to

be the relative minimum value.

After that, when the load exceeds difference X

multiplied by the relative magnification (1/4 to 4), A,

B, and the difference between A and B are held in

relative maximum hold, relative minimum hold, and

relative difference hold, respectively, at O, P, Q, etc.

If the minimum count is too small, when the waveform

includes noise as shown on the left-hand side, the noise

is regarded as the relative maximum value or relative

minimum value and a correct value may not be held. In

such a case, set the minimum count somewhat large.

■Hold setting　--- Inflection point ---

If you select the inflection point hold in the hold function setting, set the inflection point detection

parameters "inflection minimum slope", "inflection front sope time" and "inflection rear sope time".

Set referring to the principle of operation only when the value cannot be held successfully with the

factory settings or when further adjustments are required.

Detection of the inflection point

The logic of detecting the inflection point is given below.

Assuming that the remainder obtained by subtracting the amount of change C of the indicated value over

A from the amount of change of the indicated value over B is D, when the amount of change D exceeds

the inflection minimum slope, point a is held as an inflection point.

If there are two or more inflection points in the hold section, the point having a larger change is held.

The inflection point is normally detected by A=B, but it may easily be detected with A<B where the

slope is gradual.

Caution regarding inflection point hold

If the detection Inflection front sope time and Inflection

rear sope time are set too short, fine load changes may be

detected as shown in the illustration on the left-hand side,

so that a correct value cannot be held.

In this case, set the detection inflection rear sope time

large enough to bring it as close to the load change time as

possible, and also set the inflection minimum slope large

according to the amount of change at that time, so that the

inflection point is held at a correct position.

Example of inflection point hold setting

● Example of ideal waveform setting

SETTING OF FUNCTIONS

① Set the load change time (between the inflection point and when the change stops) to

② Set the same value as inflection rear sope time to inflection front sope time. ③

● If the inflection point cannot be located successfully

inflection rear sope time. In the example, it is set to 200 since it is 100 msec.

Set load D obtained by subtracting load C changing with inflection front sope time from the

load changing with inflection rear sope time to the inflection minimum slope.

In the example, set load change D=80 obtained by subtracting load C=10 changing with A

from load 90 changing with B to the inflection minimum slope.

However, since an inflection point is not judged until load change D exceeds the inflection

minimum slope, actually set the inflection minimum slope a slightly smaller than D.

① When holding above the inflection point and moving downward

1) It is considered that the inflection minimum slope is small with

respect to load change D. Set the inflection minimum slope

larger.

2) If lowering is insufficient in 1), increase inflection front sope

time.

② When holding below the inflection point and moving upward

inflection rear sope time is too long and the inflection minimum

slope is too large.Shorten inflection rear sope time and decrease

the inflection minimum slope.

How to specify the hold detection section(Peak, Valley, P-P, Average)

All section

By this method, the hold detection section is externally specified by the T/H signal.

Detection starts with the T/H signal ON to perform each hold operation.

According to the ON/OFF state of the T/H signal, detection and tracking are repeated. There is no

fixed hold section.

(Example) All section peak hold

t1: A delay time between the instant when the T/H signal is inputted and the instant when the indicated value is held

1.0ms (max.)

t2: A delay time between the instant when the T/H signal is released and the instant when the indicated value returns to tracking

1.0ms (max.)

t3: A minimum reset signal width required for releasing the hold

1.0ms (min.)

Note: During the undetermined section, the

judging output varies with fluctuations in the

input waveform. However, the H/E output

remains on during the undetermined section.

Read the judging result when the indicated

value becomes stable (immediately before the

T/H signal rises).

Chapter

External signal

By this method, the hold detection section is externally specified by the SECTION signal to

maintain the hold value until the reset signal is turned on.The hold is released by turning on the T/H

signal as a reset signal. The next detection is started when the SECTION signal is turned on again

even if the T/H signal is not turned on.

The H/E output signal is on between the instant when the SECTION signal is turned off and the

instant when the T/H signal is turned on.

(Example) Externally specified section peak hold

t1: A delay time between the instant when the SECTION signal is inputted and the instant when the value to be held is detected

Hold is detected during the predetermined time (hold section time) from the point in time when the

indicated value crosses the hold start level. The hold is released by turning on the T/H signal as a

reset signal.

The H/E output signal is on between the instant when the hold section time ends and the instant

when the T/H signal is turned on.

By this method, the hold detection section is from the point in time when the indicated value

crosses the Hold Start Level until it crosses the Hold Stop Level. The hold is released by turning on

the T/H signal as a reset signal. The H/E output signal is on between the instant when the hold

section time ends and the instant when the T/H signal is turned on.

However, there are limitations that the Hold Start Level should be passed HI and the Hold Stop

level be passed LO in peak hold, while the Hold Start Level should be passed LO and the Hold Stop

6-2. D/A Converter (Option)

A D/A converter is provided for obtaining analog output synchronized with the indicated value of

the F372A.

The analog output ranges are -10 - +10V output and 4 - 20mA constant-current output.

By using the D/A zero setting and D/A full scale setting functions, analog output can be obtained

between zero (0V, 4mA) and full scale (10V, 20mA) with respect to the predetermined digital value.

The output circuit and the main unit circuit are isolated. The resolution is 1/10000 to -10 - +10V

and 4 - 20mA, and the conversion rate is 2000 times/sec. The maximum voltage output range are

about ±11V, the maximum current output range are about 2.4 - 21.6 mA.

Error Display List

When either of the following errors occur, the RUN signal of an external output is turned off.

■Sensor +error or Sensor -error

This message indicates that the inputted electric signal exceeds the input voltage range of the element (ADC) which converts the inputted electric signal to a digital value whereby the signal cannot be converted to a correct digital value. Sensor +error and Sensor -error indicate that the inputted electric signal exceeds the input range in the positive direction and negative direction, respectively. This message may also be displayed when an excessive load is applied to the sensor or the input terminals are opened due to a break in the cable.

■+Over or -Over (Overflow error)

This message indicates that the value to be displayed except the decimal point and sign exceeds five digits. The message and a value of as much as five digits appear alternately. +OVER and -OVER indicate that the value to be displayed exceeds five digits in the positive direction and negative direction, respectively. This message is displayed in such a case wherein a load larger than expected is applied or calibration is performed below the measuring range. Check calibration and the measuring object.

■Overload (Overload error)

An Overload error results when the real time value (sensor input value) exceeds the alarm HI limit or drops below the alarm LO limit. Check the sensor for excessive load.

Chapter

SUPPLEMENTS

■Zero error (Zero calibration error)

This message indicates that calibration cannot be performed because the inputted electric signal exceeds the input voltage range. Check the cables for breaks or miswiring.

■Span error (Span calibration error)

The span calibration error occurs under the following conditions.

1) An actual load set value of zero is inputted.

2) An electric signal of -0.005 to 0.005mV/V is inputted.

In the case of 1), check the set value, and perform calibration again.

In the case of 2) , check that the actual load is properly applied and check the cables for miswiring.If the load is too light, the load needs to be increased.

Although the F372A will not break down immediately even if the above messages are displayed, Sensor +error or Sensor -error indicates that an excessive voltage may be applied to the input circuit of the F372A. It is therefore required to remove the cause immediately. (Although the input is provided with a protection circuit, a long-time excessive voltage or an instantaneous but extremely high voltage may break the F372A.)

■Zero limit (Digital zero limit error)

A zero limit error results when the range of zero-point correction (deviation from the zero calibration registered point) by digital zero or zero tracking exceeds the Digital Zero Limit set value. Reset the digital zero, or perform digital zero in an appropriate range.
