Signal Name and Function
A1 : Load Digital Zero
Performs digital zero for a load value on the ON edge.
However, the digital zero function is not available if the current load value exceeds the“zero limit setting” when the “zero balance” value of a load sensor calibration is set as
zero.
A2

: Displacement Position Adjustment
Presets a value of “Displacement Position Adjustment” (set by selecting “SENSOR
CAL.”→”DISP.”(horizontal axis)→”DISP.VOLT/DISP.PULSE” to the counter(Default: 0.0 mm) on the ON edge.

A3: Measurement Start/Stop
Typically, measurement is ready on the ON edge and measurement is terminated on
the OFF edge.
An actual measurement is started based on the conditions for starting/stopping themeasurement which are set on a work-by-work basis.
A measurement can be started based on either (1) the start signal or (2) a combinationof the start signal and load values.
A measurement can be stopped in the same fashion.

A4: Hold Command (Displacement)
Functions as a displacement value hold timing contact signal. During “Displacement
Sample Hold,” holds and judges the displacement value at the ON timing.
However, when a signal makes an ON-OFF-ON transition, the displacement value isheld at the first ON timing of the measurement.
Indication of load and displacement values is also held, but the waveform (data)
continues to be displayed.

A5: Hold Command (Load)
Functions as a load value hold timing contact signal. During “Sample Hold”, holds
and determines the load value at the ON timing.
However, when a signal makes an ON-OFF-ON transition, the load value is held at thefirst ON timing of the measurement.
Indication of load values is also held, but the waveform (data) continues to be
displayed.

A6: ResetUsed to abort all the current operations, regardless of whether they completed
successfully or not, and discard the measurement data, if errors or other abnormal
conditions occur.
The indicator will return back to the state it was when last powered on (The settings are

4-1 Calibration of Load
“Calibration” refers to an operation for matching between the TD-280T and a strain gauge sensor.
The TD-280T offers the three calibration methods as described below.
Here is the calibration of load. For displacement, two calibration methods are supported: equivalent input calibration
and real load calibration.

◇ Equivalent input calibration
This approach uses no actual loads but key entry of the rated output value (mV/V) of the strain gauge sensor andthe rated capacity (value to be displayed). This method is simple and employed when actual loads cannot beapplied.
For example, gain will be automatically determined and displayed by entering the values indicated as follows:
For load: 2.001 mV/V-100 N
For pressure: 2.002 mV/V-10.00 MPa
For torque: 2.502 mV/V-15.00 N･m

At the time of factory shipment, a data sheet is attached to a strain gauge sensor, indicating
the following values.
Rated Capacity･････････････････････ Load (Unit: kg, ton, etc.)
Rated Output･･･････････････････････ Voltage (Unit: mV/V)
Nonlinearity････････････････････････ %R.O
Hysteresis･･････････････････････････ %R.O
Input Terminal Resistance･･･････････ Ω
Output Terminal Resistance･･････････ Ω-6Zero Balance････････････････････････ x10 strain

The rated capacity and rated output are the necessary values for equivalent calibration.
For a TEDS sensor, these data are stored on the internal memory.

◇ Real load calibration
It is an accurate and low-error calibration method by applying a real load to the strain gage sensor and entering thedisplay value (load value) set on the equivalent input calibration screen.

◇ TEDS calibration
It is a calibration method using the data stored in a TEDS memory in which the rated output value (mV/V) and therated capacity of a strain gage sensor are recorded.
Two types of TEDS-compatible memories are available: 1 kBit and 4 kBit. TD-280T supports only 4 kBit memory.

- 28 -

4-2 Before Calibration◇ Setting bridge voltage
Set a bridge voltage in accordance with the specifications of a strain gauge sensor.
Note that selecting an incorrect bridge voltage may damage the sensor.
From the TOP screen, select “SETTINGS”→“DETAIL SET”→“SENSOR CAL.”→“LOAD-CELL”→“BV” to set a
bridge voltage.

Load B.V select screen (with 2.5 V selected)

Be sure to set a bridge voltage before connecting a sensor.
Incorrect connection may damage the sensor.
Caution◇ In case that indication is “unstable”/Zero balance is not achieved
If indication is unstable when a strain gauge sensor is connected and powered on or if zero balance is not achievedat the moment of calibration, the zero adjustment range (0 to ±2 mV/V) may be exceeded.
In this case, switch to the “Strain display” mode (by choosing “SETTINGS”→”DETAIL SET”→”VIEW”→”STRAIN”) and check the indicated value.
In this mode, a strain value which includes offset is shown as a sensor output. A sensor output of ±3 mV/V isindicated as 0 to ±6000 µst.

4-3 Sensor Calibration
From the TOP screen, select “SETTINGS”→“DETAIL SET”→“SENSOR CAL.”
In the Sensor calibration screen, specify settings for load sensor anddisplacement sensor calibrations and measuring time.

key to set a desired value, and then push

the “Update” button to confirm.
To change the decimal point position of the indicated value, place the cursor
over the decimal point, and use thekey to move the decimal

point.
4-3-1-2 Real Load Calibration
Prior to performing a real load calibration, select “EQUIV. INPUT” and set an actual load value as “DISPLAY” value inthe Equivalent input calibration screen. This load value is reflected in “Real load calibration.”
From the Load sensor 1 screen, select “REAL LOAD” to perform “ZERO” and“MEASURE.”

ZERO (Zero point measurement): With the load sensor unloaded, push the“ZERO” button to set the zero point of the sensor.
A bar is displayed indicating the zero point amount. The

Caution) You need to connect a TEDS-capable sensor to TD-280T if performing TEDS calibration.

- 31 -

◇ Rated capacity display digit in TEDS calibration
A TEDS calibration performs a sensitivity calibration by retrieving the memory data in the sensor. A sensor is available
in various rated capacities (display values).
In TEDS calibration, TD-280T displays rated capacity values as shown in the table below.
The TEDS calibration data is stored in TD-280T. Thus, if any changes to display values are required after thecalibration is performed, return to the Equivalent input calibration screen and change the value of “DISPLAY” and its
decimal point position.

Load HI LO limit screen
When constant judgment is enabled in the Load sensor
screen, the hysteresis function becomes effective.
Caution- 72 -

When you set a value other than 0.0 in “HYS”, the hysteresis function becomes effective.
・ Once the HI judgment output becomes ON, the state continues until a measured load value falls below a value
obtained by subtracting the hysteresis value from the HI limit value.
・ Once the LO judgment output becomes ON, the state continues until a measured load value exceeds a value
obtained by adding the hysteresis value to the LO limit value.
HH judgment and LL judgment function similarly.
A hysteresis setting value is common to all load limit values.
If a hysteresis value is large, for example, so that a value obtained by subtracting the hysteresis value from the HI limit
value overlaps the LO limit value, a judgment result based on the HI and LO limit values takes precedence over a
judgment result in which a hysteresis value is considered.
Once a value is held, the held value is compared against the HI and LO limit values and the comparison result isjudged and output.
◇ When “MANY” hold is set
When “MANY” hold is set, load is be judged against HI and LO limit values.

Multiple-zone judgment checks whether hold values falls within thedetermined zones.
Example of a graph before
measurement is performed
When measurement is performed, if all the hold values fall within the zones,
judgment result is OK.

Example of a graph when
judgment result is OK
If at least one of the hold values falls outside of the zones, judgment result isNG.

7-2-5-4 Special Judgment Output◇ Judgment NG output
When comparing and judging hold values, comparison output (HH, HI, GO, LO, LL) may not be applied. This caseis called “judgment NG,” and can be output by assigning to the HI and LO signals for comparison outputs.
Usually, for judgment NG, comparison output (HH, HI, GO, LO, LL) is not changed, and therefore judgment NG can
not be detected from comparison output. In such a case, the judgment NG output function detects judgment NG by
assigning judgment NG to the HI and LO signals for comparison output.

The analog output has a range of 0 to ±10 V for voltage output or from 4 to 20 mA for current output.
For any digital value you have set with the D/A zero setting and the D/A full scale setting functions, you can obtain an
analog output of zero (0 V, 4 mA) to full scale (±10 V, 20 mA).
The D/A output circuit and the main circuit are isolated. The resolution is 1/±10000 for 0 to ±10 V and the conversion
rate is 500 times per second. The output has an over range of about +10%.
A current output of 4 mA corresponds to a voltage output of 0 V, and a current output of 20 mA corresponds to a voltage
output of 10 V.
Use a current output of 4 mA (0 V) to 20 mA (+10 V).

Communication speed
On a transmission of load and displacement, C54 or beyond requires a communication speed of 19200 bps or
more.
Processings when the transmission is stopped by flow control
When the transmit buffer has enough free space, the current value is written into the transmit buffer.
After the transmit buffer is full, the current value is not written into the transmit buffer.
Therefore, the number of data and the measuring time may be inconsistent.
About data transmission
The RS-232C controller has its built-in FIFO transmit/receive buffers and transmits data collectively for efficient
data transmission.

11. Overscale/Error Displays
This section describes overscales and errors which may be displayed on each screen.
11-1 Errors Related to Load Sensor
LOAD:
This error indicates that an input signal from the load sensor exceeds +3.0 mV.
It also indicates that a sensor signal exceeds 3.0 mV/V. The sensor and thecables require to be checked.
If you encounter this error during use of the system, possible causes include an
overload on the sensor, etc.
From the TOP screen, select “SETTINGS”→“DETAIL SET”→“VIEW”→“STRAIN” and then check an indicated value. If the indicated value is larger
than a rated output (4000 to 6000) of the connected sensor, a failure may occur
in the sensor.

−LOAD:
This error indicates that an output from the load sensor goes beyond thenegative limit value. The sensor and the cables require to be checked.
As in the LOAD error, select “STRAIN” so as to check an indicated value. For
possible causes, refer to the description of the LOAD error.

FuLL:
This alarm indicates that an overflow of a positive indicated value occurs.
For example, suppose that a sensor rated-output of 1.234 mV/V is set to
an indicated value of 5000. If an input from the sensor goes beyond 2.468
mV/V, the indicated value exceeds 9999, which causes the indicated valueerror “FuLL.”
This error relates to an indicated value. However, note that when
“FuLL”occurs, the sensor also is overloaded (i.e. an output from the sensor
exceeds the rated output).

-FuLL:
This alarm indicates that an overflow of a negative indicated value occurs.

- 104 -

11-2 Errors Related to Displacement Sensor
FULL:
This error appears when a displacement value is positive and is too large to fit
within the number of digits allowed available on the display.
For example, suppose that a value is displayed to one decimal place. In thiscase, a larger value than 999.9 causes this error.

-FULL:
This error appears when a displacement value is negative and is too small to fit
within the number of digits allowed available on the display.
For example, suppose that a value is displayed to one decimal place. In thiscase, a smaller value than −999.9 causes this error.

◇ Errors related to displacement sensor (pulse output)
You can clear these errors by performing the displacement adjustment.
OVER:
This error appears at the lower right on the screen when the pulse count goesbeyond 65535, thereby causing the overflow of the pulse counter.

UNDER:
This error appears at the lower right on the screen when the pulse count isnegative, thereby causing the underflow of the pulse counter.

OVER UNDER:“OVER UNDER” is displayed when the pulse count recovers to a value within
the correct range after the pulse counter overflows or underflows.

Error notification on the graph display screen
If the pulse counter encounters any error, the background of the letters“Displacement” located at the lower left on the screen is shown in red.
Contents of errors can be shown by pressing the “VIEW” button to switch to thenumeric display screen.

11-3 Errors During Load Sensor Calibration◇ Errors during real load calibration
Input-range over error
This error shows that the signal from the sensor exceeds the input range(3 mV/V) of the indicator. This 3 mV/V includes the zero point of the sensor.

Input-range over error screen

Zero balance error
This error shows that during zero point measurement, the signal from thesensor is larger than ±2 mV/V. Check a zero balance value, and then adjust it
to 2 mV/V or less.

Zero balance error screen◇ Error during equivalent input calibration
Refer to the sensor data to enter the correct rated output. A rated output lager
than 3 mV/V is an input over and therefore cannot be set.

Input over error screen◇ Error during TEDS calibration
This error shows that a TEDS sensor is not connected to the indicator.
Check the connection between the sensor and the indicator. Further, makesure that a TEDS-capable sensor is used.
