Precautions for Use

This unit is not water or splash-resistant. Avoid using it in high relative humidity or atmospheres with corrosive gases.
Prevent water, oil, and other substances from getting on the unit.
Avoid use in conditions where condensation could occur.
Discharge static electricity from your body before connecting the load cell.
Sudden changes in surrounding temperature may affect the accuracy of measurements. Calibrate the load periodically.

Product Usage Instructions

Installation Procedures

Install the load cell in a level place that can bear the load being used.
Remove any oil from the mounting surface and attach the load cell using double-sided tape or adhesive. Alternatively, attachment using a housing is also possible.

Note: Refer to the product manual for detailed installation instructions and diagrams.

IMPORTANT SAFETY INSTRUCTIONS

WARNING
If something abnormal occurs
In the unlikely event that the product produces smoke, a strange smell or noise, for example, continuing to use it in this abnormal state could cause fire or electric shock. After cutting off the power, confirm that smoke is no longer being produced. Then, request repair from the retailer where you purchased the product.

Precautions when placing loads on the unit.

Make sure the load is perpendicular to the surface to which this unit is attached.
Apply the load so that it is centered on the center of the unit. If the load is not centered (eccentric load), twisting, for example, and measurement errors could occur. This could even result in damage
Be careful to avoid turning and twisting from lateral loads. This could cause troubles like those described in the previous item.
Be careful to avoid applying loads that exceed the rated capacity. In particular, use caution when there are vibrations because loads that exceed the rated capacity could occur due to sympathetic vibrations, for example.
If the load-receiving area (spherical surface) is contacted by something that is at a different temperature and the load is increased, the values output by this device could become unstable, making accurate measurement impossible. In such a case, wait until the temperature difference ceases to exist before measuring.

Do not open the cover.
Never remove the cover from this unit. Doing so could cause an electric shock. Request inspection and repair from the retailer where you purchased the product. Do not alter this unit. Doing so could cause fire or electric shock.
Do not put foreign objects or water, for example, into the unit.
Do not place a container that holds water, for example, on top of this unit. Liquid overflowing or entering the unit could cause fire or electric shock.
Do not use the unit with any power supply voltage other than that specified.
Do not use the unit with any power supply voltage other than that specified. Doing so could cause fire or electric shock

CAUTION
Unsuitable installation locations

Do not place the unit in the following types of locations.
Doing so could cause fire or electric shock.
Locations where it might be exposed to smoke or steam, such as near a kitchen table or humidifier
Unstable locations, including unsteady stands and tilted places
Location that are very humid or dusty
Locations that are exposed to direct sunlight

When not using the unit for a long time
For safety, cut the power supply when not using this unit for a long time.
Do not operate a damaged unit

Precautions for use

This unit is not built to be water or splash-resistant, and it cannot be used in conditions when the relative humidity is high. Moreover, use in atmospheres with corrosive gases should be avoided.
Be careful to prevent water, oil and other substances from getting on the unit.
Avoid use in conditions where condensation could occur.
Connect cores to the load cell after discharging (eliminating) static electricity from your body.
If the surrounding temperature changes suddenly, the

Electrical connection of load cell with built-in TEDS

Connect as shown in the illustration below. Incorrect connections could result in an inability to balance and in errors occurring in the output voltage when loads are applied

Using a cable with bare lead wires

This unit has a built-in TEDS function. The orange and green cores in the cable and the F and G pins in the connector are wired for TEDS.
This unit does not support remote sensing.
Since products that support remote sensing use the same cables and connector pins as TEDS, be careful not to try mistakenly to use these pins for remote sensing. See the operation manuals of indicators and strain amps that support remote sensing for how to connect sensors with those units.
The shield is not connected to the main body of this product. For this reason, if grounding is necessary because of external noise, for example, arrange to ground the shield to a part other than the body of this unit.
values output by this device could become unstable, making accurate measurement impossible. (This could occur, for example, in a location blown by warm or cold air.)
Conduct load calibration periodically.

Installation procedures

Install this unit in a place where the structure is level and can sufficiently bear the load being used.
Remove any oil from the mounting surface and attach it with double-sided tape or adhesive, for example.
Attachment using housing is also possible

Attachment example

Since the cable is directly connected to this unit, use a specialized cable to increase the length. (Please consult with us.)
When conducting insulation resistance tests, limit themto the red, black, blue and white cores. Do not apply to the TEDS cores (orange and green).

TEDS overview

TEDS (Transducer Electronic Data Sheet) is a memory chip that can electronically read and write sensor-specific data. The TEDS built into this unit has serial number, load cell rated output and manufacturer name data recorded on it. By connecting an indicator that supports TEDS, the TEDS data of the connected load cell will be automatically read and equivalent input calibration will be completed. (For details, read the operation manual of the connected indicator.) Refer to the connection diagrams in the “Electrical connection of load cell with built-in TEDS” section as well as the operation manual for the indicator being connected for procedures to make connections. TEAC indicators that support TEDS include the TD-01 Portable, TD-700T, TD- 260T, TD-275T, TD-280T and TD-9000T. For details, inquire at a shop that handles these products. If not using the TEDS function, do not connect the orange and green load cell cores. Moreover, take measures to prevent the orange and green cores from touching other terminals. Data recorded in TEDS are tested values from calibration conducted at room temperature during inspection before shipping from our company. Load cell output will be affected by the environmental temperature where used, even when within the compensated temperature range established in the specifications. Although load cell output is calculated from the calibration value saved in TEDS, when the environmental temperature differs greatly from room temperature, the temperature impacts increase on the zero point and the output. Forthis reason, consideration of the effect on output voltage is necessary. Output voltage changes will be within the specification range as long as the unit is used at temperatures within the specification range.

When using the TEDS function
This product’s cores for TEDS (orange and green) are protected by a plastic cover as shown in the illustration. This is to prevent miswiring and contact with other connectors during use, for example, which could cause shorting. To use the TEDS function, remove the tip of the plastic cover, following the perforations, from the end of the cables. Then, connect the TEDS cores (orange and green) to the indicator. Refer to the “Electrical connection of load cell with built-in TEDS” section for how to connect each wire.

When not using the TEDS function
If not using the TEDS function, remove the entire protective plastic cover and cut off the TEDS cores (orange and green)around where the plastic cover was attached to the cable. If you use it without removing these cores, do not remove the protective plastic or make other arrangements to prevent the cores from touching other places. Refer to the “Electrical connection of load cell with built-in TEDS” section for how to connect each wire.

NOTE
Explanations related to TEDS are available on our website. https://loadcell.jp/en/info/teds.html
ATTENTION
Since the protective plastic and tag are not suitable for the entire temperature range of this unit’s specifications, do not expose them to high temperatures

Handling after use

When moving this unit while it is installed, take protective measures to prevent it from being shaken or subjected to excessive external forces.
