Chapter 2 Parameter SettingAnd Operating

Section1 Calibration

User needs to calibrate load cell on initial operation. Press 3 key ,then

press EN key, system will indicate to input password, see below textbox:

After input password, system comes into calibration page. Input serial No.

of bucket to calibrate each sensor. Press ESC to return to calibration page as

below:

Input password * * * * * *



6/16


1. Input the weighbucket number (eg NO.1),then the weigh of the

bucket or other unstable values will be displayed (before initial

calibration),and thecursor will advancetoZERO .

2. Press ENIER key for zero confirmation (empty the weighbucket

that), andthevaluedisplayed remainsunchanged .

3. After thecursor moves from ZERO to FULL, put a standard weigh

on the weigh bucket (refer to the value shown on the screen) and

press ENTER key for confirmation, then thecorresponding value

will bedisplayed (eg1000.0).

4. Test : put another standard weight (eg 500g )on theweigh bucket, if

the corresponding value is displayed ,the weigh bucket has been

calibrated successfully.

5. Input thenext weighbucket number ,thencalibratetheweighbucket

byfollowingprevioussteps.

Note: The whole calibration should be done under the wind-free and

vibration-freecircumstances.

Section2 Parameter Setting

Press 2 key, then press EN key. Input new password to enter into

parameter setting page. See textbox below:

0

Move cursor to the parameter needed to change, input new parameter

directly, then press EN key to store new parameter and press ESC key not to

store it. Please find exegesis as follow:

Formu No. : of Formula (from 0 to 9) means: system can store ten types of

formulas of different products or different weight.

DateSet: move cursor and input digit keys to set date.



8/16


TimeSet: move cursor and input digit keys to set time.

Zero-D-T : (from 1 to 99 minutes) means: system make zero every one

minute and prevent zero position to shift. It takes 0.5 second to make

zeroing. If time is too short, it will affect speed.

Det-way: (0 and 1),When test way is 0, which means it inputs trough

pulse. And edge down is efficacious. When test way is 1, which means

it inputs though voltage. Connecting 21-36 directly, it means weighed

product would be fed immediately.

Ove-Times: (1to15 times)

Feed Way: there is two ways, one is 0, and the other is 1. 0 means

there is no collection bucket. 1 means there is collection bucket.

Fd Delay: (from 1 to 99 seconds)50 millisecond means: When linear

weigher receive signal sent by other machine connected to it, linear

weigher will prolong (1 to 99 seconds)5 millisecond, then send signal

of Product adding to other machine.

Feed Time: When linear weigher receive signal sent by other machine

connected to it, then linear weigher will prolong (1 to 99 seconds)5

millisecond and send signal of Product adding to other machine.

Back Set: two digits show the apheliotropic setting. One is 0, which

means apheliotropic lamp shuts off automatically after user does not

operate keyboard for 30 seconds. The other is 1, which means

apheliotropic lamp keep lighting.

Per Add: when product reaches (1 to 99%, can be chosen) of target weight,



9/16


feeding speed will go slow. For example, target weight is 100 gram,

quantity of feed product is 98%.

Fa-F-Time:speedy feeding restrict time (1 to 999 *50ms)

Tar weight: target weight can be set from 5 gram to 1000 gram.

Up limit: Maximum weight of capacity. If target weight exceeds up limit,

weight check facility willeact.

Lowlimit: Minimum weight of capacity. If target weight is less than low

limit, weight check facility will react.

password:password set is 111111. Input new password (six digits)to

prevent someone to amend parameter by mistake. If you forget

password, please contact us.

Vibra Amp Add.Q Add.S State

1# 50/52 10/30 1

*1# means bucket No.1.

*50/52means swing of up vibrator is 50 and swing of below vibrator is 52.

*10/30means swing of up vibrator is 10 and swing of below vibrator is 30.

*1or 0: 1 means machine runs, 0 means machine stops.

6. AmplitudeAutomatic Follow-upCorrection

Amplitude will be automatically corrected according to weighing

accuracy and speed while running to achieve the optimal weighing

status.

Related parameters: over weight times: 1-15time

timeof addingquickly : 1-999 50ms

Over weight correction : Taking 15 packages as a count unit for

each weigh bucket ,if the quantity of packages weighing beyond the

upper limited weight is more than that of over weight times ,the

Slow speed correction :Taking 15 packages as a count unit for

each weighbucket , if thequantity of packages packed when timeof

adding quickly surpasses its setting parameter is more than that of

over weight times, thesetting parameters of upper and lower limited

Section3 Automatic trackingof weight

During machine running, vibrator swing can be amended automatically

according weighing accuracy and speed to get optimum state. Please find

below course and parameter setting.

Relevant parameter: Ove-Times (1 to 15 times);

Fa-F-Time (1 to 999 *50ms)

over weight amending: every weight bucket is separate and taking 15

dosages as a unit. If dosages over up limit exceeded set value of

Ove-Times, the front vibrator and back vibrator swing of speedy

vibratory feeding would reduce 1 at the same time.

Lowspeed amendment: every weight bucket is separate and taking 15



12/16


dosages as a unit, when speedy vibratory feeding happen, if the time was

more than set value of Fa-F-Time, the front vibrator and back vibrator

swing of speedy vibratory feeding would add 1 at the same time.

*Attn :if you want to store automatic amending swing value, please come

to Amp Set of Set and press EN key to store.

Section4 Manual Adjustment

User needs to test quantity of product fed after amending parameter. User

can adjust menu manually. Press 5 key, then press EN key to adjust

menu. See below textbox:

A.Feed and Motor test

Touch *A on the screen, it will indicate to input 1, 2, 3 and 4 ( serial No.

of buckets), which allows to test whether vibrator and motor works well ,

and whether below vibrator and up vibrator feeds product in average.

Input 5 to see the difference of the four vibrators. Adjust swing of vibrator

to get similar swing speed.



13/16


B.Feed test

Input double digits to test the product of quick vibration and slow

vibration for one second. Generally, product of quick vibration for one

second is 20 to 50 per cent of target weight, and product of slow

vibration for one second will not exceed 10 per cent of target weight.

User can amend parameter setting of vibrator swing to get similar weight

of each bucket. In this way, product weight of four buckets will keep

similar.

C.Empty doser

In case, user wants to examine and repair vibrator, first close the gate of

loading hopper, then clean remainder.

Section 5 AccuracyAdded Up

After test, check out accuracy. Press 4 key, then press EN key to

enter Accuracy added up page, see below textbox.

Before adding up accuracy, it is necessary to clean previous record. After

linear weigher running some time, please return to Accuracy Added Up page.

On the screen, user can see mean error, total error and standard rate. In this

way, user can decide whether it is necessary to reset parameter. To clean out

all counting results, press EN key. To store data, press ESC key to exit.

Section6 Wireconnectingof signal instruction

1. Input

relevant parameter: Det-way (0 or 1)

Product feeding request: wire number is 36-21. This signal has two ways.

When Det-wayis 0, which means it inputs trough pulse. And edge

down is efficacious. When test way is 1, which means it inputs though



15/16


voltage. Connecting 21-36 directly, it means weighed product would

be fed immediately.

Product level up limit: wire number is 33-21.

Product level low limit: wire number is 34-21.

2. Output

feedingtime (1 to 99 *50ms); prolonging time for product dropping (1 to

99 *50ms)

Clearance: wire number is 23-22, it means machine is making clearance.

Less than: wire number is 24-22, it means current weight is less than low

limit and is input with feeding signal at the same time.

More than: wire number is 25-22, it means current weight is less than up

limit and is input with feeding signal at the same time.

Product adding: wire number is 26-22, it means control of product level of

hopper. Input product low limit, then product adding will be output.

Product level up limit is input, then product adding will stop.

Ready: wire number is 27-22. After product weighing is finished, signal

will be output.

Product dropping: wire number is 28-22. It is a signal of 4 head linear

weigher giving to other machines combined with it.Fd-Delay (Prolong

time for product dropping) is t1.Feed Time(Product dropping time) is

t2,
