Precautions for Use:
- Avoid using the load cell in environments with high relative humidity or corrosive gases.
- Prevent water, oil, and other substances from coming into contact with the unit.
- Avoid conditions where condensation could occur.
- Discharge static electricity from your body before connecting the load cell.
- Be aware that sudden temperature changes in the surroundings may affect the accuracy of measurements.
- If bending and shifting the cable is necessary, maintain a minimum curvature of 60 mm and avoid applying tension to the cable.
- Perform load calibrations periodically.
Installation Procedures:
Refer to the user manual for detailed installation instructions, including component diagrams and set screw tightening procedures.
After connecting rod end bearings, tighten the set screws to prevent rotation. Ensure that the set screws are not loose before use.

IMPORTANT SAFETY INSTRUCTIONS

WARNING

If something abnormal occurs
Request repair from the retailer where you purchased the product.
Do not open the cover.
Never remove the cover from this unit. Doing so could cause malfunction. Request inspection and repair from the retailer where you purchased the product. Do not alter this unit.
Doing so could cause malfunction.
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. If liquid is spilled, for example, and enters the unit, this could cause malfunction.
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 malfunction.

CAUTION

Unsuitable installation locations
Do not place the unit in the following types of locations. Doing so could cause malfunction.
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
Locations 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 (elim- inating) static electricity from your body.
If the surrounding temperature changes suddenly, the 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.)
If a cable of this unit needs to be bent and shifted, make the curvature of the bent part at least 60 mm. Do not apply tension to the cable. Conduct load calibrations periodically.

Installation procedures

The top and bottom surfaces each have a single male screw for attachment. Attach rod end bearings to them for use.
Lock nuts, for example, cannot be used to tighten the rod end bearings to the load cell. The load cell attachment screw parts are chamfered, though, so use these surfaces to secure the set screws.
After connecting rod end bearings, tighten the set screws to prevent rotation.
During inspection before use, confirm that the set screws are not loose and that there are no signs of turning.
After installing a load cell, confirm that the cable will not be pulled.
Pulling on the cable could result in error.
Verify that safety measures to prevent falling and dropping have been implemented.

Electrical connection of load cell with built-in TEDS

Connect as shown in the illustration below. Incorrect connections could result in 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 sense.
See the operation manuals of indicators and strain amps that support remote sense 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 or another issue, arrange to ground the shield to a part other than the body of this unit, for 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 them to the red, black, blue and white cores. Do not apply to the TEDS cores (orange and green).

Using a connector (optional)

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 “Electrical connection of load cell with built-in TEDS” as well as the operation manual for the indicator being connected for procedures to make connections.
TEAC indicators and signal conditioners that support TEDS include the TD-01 Portable, TD-700T, TD-260T, TD-9000T and TD-SC1. For details, inquire at the retailer where you purchased the unit.
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 compen-sated 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. For this 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 connec-tors 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 “Electrical connection of load cell with built-in TEDS” for how to connect each core.

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 “Electrical connection of load cell with built-in TEDS” for how to connect each core.

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.
When storing it, keep it in a dry place where it will not be exposed to water or oil, for example.
