IMPORTANT SAFETY INSTRUCTIONS

WARNING
If something abnormal occurs Request repair from the retailer where you purchased the product. Do not open the cover. With tensile load M3 screw holes for hexagon socket set screws in two locations to stop rotation and prevent falling 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 the 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 where the relative humidity is high. Moreover, used in atmospheres with corrosive gases should be avoided.
• Be careful to prevent water, oil, and other substances from getting on the unit.
• When there is a tensile load, be careful not to apply

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. bending loads or twisting.
• When using a tensile load, we recommend a rod end.
• Be careful to avoid applying loads that exceed the rated capacity.
• If used in a location with vibrations, consider resonance phenomena and other factors when choosing the rated capacity.
• 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 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 50 mm. Do not apply tension to the cable.
• Conduct load calibrations periodically.

Installation procedures

• When using with a tensile load, attach a rod end.
• When attaching a rod end to a load cell, use a nut to prevent loosening.
• Use a wrench (12mm width across flat) when tightening the nut.

(Caution : When tightening the nut, be careful not to apply a twisting load (momentum) to the load cell itself. Doing so could cause damage, for example.) o After connecting a rod end, screw in and tighten the hexagon socket set screws into the two M3 screw holes on both sides of the load cell to prevent rotation. During inspection before use, confirm that the M3 screws are not loose and there are no signs of turning.

• 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. 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 nit, 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 a 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.

Dimensional drawing

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