Thank you very much for your purchasing BONGSHIN Digital Weighing Indicator of BS-7300.

This Instruction Manual will lead you to use BS-7300 with top reliability, High speed, high accuracy.

BS-7300 is Digital Weighing Indicator amplifying the analog output from a load Cell, converting the analog signal to digital data and then displaying this data

As a weight reading and is designed for flawless performance in your demanding

Application of input-weighing, output-weighing, accumulating-weighing, 2step control.

Also, an additional option will make Modern Industry demand equipment that both versatile

And availed to easily connect to other devices

☞ REMARK

- Specification subject to change for improvement without prior notice. - If changing, the Version No can be increased, but keeps a former version

■ SAFTY CONDITIONS To avoid an electric error such as a noises in your production line It should be earthed before installation certainly.

Please keep the following using conditions certainly

Specially it will be safety to divide the power of Indicator into a load cell. Don’t use it closed to a explosive gas and an inflammable dust

environments

■ POWER

■ TEMPERTURE CONDITIONS

Operating Temperature : -10o C ∼ +40o C ( +14o to 104o F ) Custody Temperature : -40o C ∼ +80o C ( -40o to 176o F )

■ INSTALLATION LOAD CELL

- Available to use the same load cell of 8pcs ( 350Ω standard ) - A ground should be installed horizontal

- Installing over 2pcs of load cell, please connect each line in parallel and Insert a variable resistor under 50Ω in EX + line and minimize a output

Accuracy of load cell.

It may occur a weight error by each accuracy of load cell. - It may occur a weight error in case of a temperature variation of load cell

- Please weld(elect spark) at the place installed with load cell and equipments,

Divide the power into a connector of load cell in inevitable case - Please connect the below construction of load cell with the above ones using The earth to the weighing part weighing a material occurring a electro

sparks.

Use the power under 110/220V 50/60HZ ±10% and divide it into the power line

Calibration is performed for matching the BS-7300 to a strain-gage sensor. The following two type of calibration are available for the BS-7300.

%\"󰀔󰀔G]ai`Uh]cb󰀔58>IGHA9BH󰀔

▣ Equivalent input Calibration.

Calibration is performed without an actual load by entering the rated output value (mV/V) and the capacity (to be indicated) of the strain-gage sensor by the keys. Calibration is easily performed when no actual load is available.

For example, the gain is automatically determined by entering. 2.0000mV/V (rated output)-100.0kg (capacity) as indicated for a load.

- RS-422 is to transmit the signal by the power difference.

Also, it is more safety rather other interface system for a electric noise. - Specially please use the cable with shield coax cable surely. - Recommended distance is under 1.2 km.

- Both end side of a wire must be connected by the termination of

300Ω.
