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 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

Tighten with the torque shown in the table below to prevent the load button from becoming loose. When removing an attached load button, be sure not to apply torque that exceeds the tightening torque shown in the table.
Rated capacity| Tightening torque| Load button screw dimension
---|---|---
500 N – 3 kN| 13 N·m| M8
5 kN – 10 kN| 6 N·m| M6

A thread-locking fluid can be used on the screw, but be aware that this could prevent removal of the load button.

Install this unit in a place where the structure is level and can sufficiently bear the load being used.
Screw holes for attachment are located in four places.
The screw dimensions are shown in the table below.
Model| Screw size| Tightening torque
---|---|---
TC-LPR(T)-G6| M4 (depth 4)| 3.5 N·m

Use class 12.9 strength screws.

ATTENTION

When using TC-LPR(T)500N-G6 – TC-LPR(T)3KN-G6
As shown in the illustration below, there is a 0.5mm level change between the outer circumference and the central screw portion of the load cell attachment surface.
For this reason, be aware that if the attachment surface is uneven, rough, dusty or dirty, for example, and it contacts the bottom of the unit, inaccurate measurement results could occur at loads lower than the rated capacity.

When using TC-LPR(T)5KN-G6 – TC-LPR(T)10KN-G6
As shown in the illustration below, there is a 1mm level change between the outer circumference and the central screw portion of the load cell attachment surface.
For this reason, be aware that if the attachment surface is uneven, rough, dusty or dirty, for example, and it contacts the bottom of the unit, inaccurate measurement results could occur at loads lower than the rated capacity.

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 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.

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

$TEAC TC-LPR$T$-G6 Compression Load Cell-fig4$

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 tempera-tures 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 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 “Electrical connection of load cell with built-in TEDS” 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.
When storing it, keep it in a dry place where it will not be exposed to water or oil, for example.
