V CAUTION Unsuitable installation locations Do not place the unit in the following types of locations. Doing so could cause malfunction. o Locations where it might be exposed to smoke or steam, such as near a kitchen table or humidifier o Unstable locations, including unsteady stands and tilted places o Locations that are very humid or dusty o 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 o 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. o Be careful to prevent water, oil and other substances from getting on the unit. o Avoid use in conditions where condensation could occur. o Connect cores to the load cell after discharging (elim- inating) static electricity from your body. o 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.) o If a cable of this unit needs to be bent and shifted, make the curvature of the bent part at least 20 mm for the 2 cable part and at least 50 mm for the 3 cable part. Do not apply tension to the cable. o Conduct load calibrations periodically. Installation procedures To use load buttons, screws, bolts and rod ends, for example, with this load cell, attach them to the screw holes in its top and bottom. Rod end use example Load button use example 3 Tensile load Output polarity () Compression load Top threaded Output polarity (+) portion c Cover Bottom threaded portion c Base plate ATTENTION o When attaching a load button or rod end, for example, to the screw/bolt area on the top of the load cell, use the included jig to hold the area shown with diagonal lines at the top and tighten the screw or nut. Jig for tightening Wrench (commercially-available) o In the same way, when attaching a rod end or base, for example, to the screw/bolt area on the bottom of the load cell, use the included jig to hold the area shown with diagonal lines at the bottom and tighten the screw or nut. Jig for tightening o When tightening the screw or nut attached to the load cell, holding the screw/bolt part on the opposite end (shown with diagonal lines), will cause twisting force to be applied to the gauge and break the load cell. Wrench (commercially-available) Jig for tightening Do not hold opposite end! o There is a gap between the load cell and its cover. Measurement errors could occur if foreign materials enter this space or if the cover becomes deformed causing it to contact the load cell. o Do not hold the cover because it is delicate. M3 4.5 mm Area with cover attached Cover o When using a rod end or other tension jig, affix the attachment areas shown with diagonal lines in the same way as with compression so that twisting force is not applied to the sensor part. o When using with tension, consider the detent of all the screws, and consider implementing inspections before starting work, for example. o Consider examinations to prevent accidents caused by falling objects due to damaged load cells resulting from overloads and unbalanced loads, for example. o Since this load cell is made with aluminum material, we recommend using flat washers suitable for the screws and bolts being used. o After installing a load cell, confirm that the cable will not be pulled. o Pulling on the cable could result in error. Guide the cable so that it extends from the load cell in a level manner. Wrench (commercially-available) Cable Detection (sensor) part M3 4.5 mm 1 Gap o Do not screw the threaded parts of load buttons, screws, bolts and rod ends, for example, into the load cell to a depth of more than 4.5 mm. Doing so could cause malfunction. o The dimensions of the screw holes in the load cell are equivalent to M3. Precautions when placing loads on the unit With tensile load (negative output polarity) o Make sure the load direction is perpendicular to the load cell. o 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. Arrows show load directions in the illustration below Correct load orientation With compression load (positive output polarity) o Make sure the load is applied perpendicularly to the load cell. Make sure that the load is also applied in alignment with the load-receiving screw hole. If the load is not centered (eccentric load), twisting, for example, and measurement errors could occur. This could even result in damage. Correct load orientation Angled load Eccentric load GOOD BAD BAD Electrical connection of load cell o 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 Red Input (+) Black Output (-) Blue Input (-) White Output (+) Fixed on one side TEDS Orange TEDS signal (+) Green TEDS signal (COM) BAD GOOD Angled load BAD Lateral load o Be careful to avoid turning and twisting from lateral loads. This could cause troubles like those described in the previous item. o 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. o 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. Shield o This unit has a built-in TEDS function. o The orange and green cores in the cable and the F and G pins in the connector are wired for TEDS. o 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. o 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. o Since the cable is directly connected to this unit, use a specialized cable to increase the length. (Please consult with us.) o 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) A Input (+) B Output (-) C Input (-) D Output (+) TEDS F TEDS signal (+) G TEDS signal (COM) E Shield NDIS-compatible connector 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" 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-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 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" for how to connect each core. Cores for sensor Load cell cable Perforations Protective plastic Cores for TEDS (orange and green) 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" for how to connect each core. Note about the tag attached to the TEDS cable 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 o When disconnecting a rod end, follow all the precautions in the Installation Procedures. o When moving this unit while it is attached, take protective measures to prevent it from being shaken or subjected to excessive external forces. o When storing it, keep it in a dry place where it will not be exposed to water or oil, for example.
