Thank you very much for your purchasing BONGSHIN Digital Weighing

Indicator of BS-7300XL.

This Instruction Manual will lead you to use BS-7300XL with top reliability,

High speed, high accuracy.

BS-7300XL 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

As far as possible



&"G5:HM7CB8=H=CBG

Please keep the following using conditions certainly

■

EARTH

To avoid an electric error such as a noises in your production line

It should be earthed before installation certainly.

Specially it will be safety to divide the power of Indicator into a load cell.

■

SAFTY CONDITIONS

Don’t use it closed to a explosive gas and an inflammable dust

environments

■

POWER

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

power line

■

TEMPERTURE CONDITIONS

Operating Temperature : -10o C ∼ +40o C ( +14o to 104

o F )

Custody Temperature : -40o C ∼ +80o C ( -40o to 176

o 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.

'":YUhifYg

-24bit sigma-delta A/D converter for high accuracy Easy

* The Key operating can be permitted or prohibited by dip switch.

* When pushing the key, it sounds "OK".

* Each Key works either a single function or compound functions.

A compound function key will be a command key when it push first

and According to the command key, the fixed value works its function,

The key to finish a input data is ENTER Key.
