SAFETY PRECAUTION

The integrated circuits used in this equipment are highly immune to noise and RFI when properly installed in the unit.

The terminal on the rear panel must be grounded directly, not with the AC ground.

Therefore, when shipping please always use original packing (conductive material) for shiping. Remove equipment from the shopping container and examine the external surfaces of the equipment for physical damage.

The A 810 should be positioned in a safe area with no combustible gas, the operating temperature is

+14°F to 104°F (-10°C to +40°C), storage temperature -28°F to 185°F (-20°C to +85°C)

Confirm the AC voltage of all equipment before power-up. The A 810 can operate within a -15% to + 10% voltage variation.

3. How to get started

At delivery the A810 is preset on default parameters (comply with legal-for-trade) to operate as a simple scale provided the resolution is set and the calibration has been carried out.

The following section explains how to setup the instrument according the required function by using the front panel keypad and display.

As an option a sophisticated Windows® based setup program is available to make the adjustment easier and faster. Via PC-Programm all parameter can be saved for backup in a separate file, the print image is changable and A810 can send weighing- and status-strings to PC via commands (see separate information).

4.1. Modes of Operation of the Serial Interfaces

Each of five serial interfaces of an A810 terminal is suited for the asynchronous exchange of data in full duplex mode.

4.2. Exchange of a Character

4.2.1. Data Exchange Parameters

The following data exchange parameters are available and have to be set in line with the characteristics of the peripheral device:

Baud rate, Bit/s:

Data bits, parity:

Stop bits:

1200, 2400, 4800, 9600, 14400, 19200, 38400, 76800

8Bit, none / 8Bit, even / 8Bit, odd / 7Bit, even / 7Bit, odd

1

4.2.2. Character Coding

The 7-bit or 8-bit ASCII code is used for the coding of characters depending on the characteristics of the peripheral device and the mode of data safeguarding. Please pay attention to the following constraints:

The 8-bit code has to be selected when a printer with an 8-bit character set (IBM 2) is used and the 8-bit characters are exploited in full (umlauts, graphics characters). Data safeguarding by means of block check sum requires the 7-bit code but this will be the exception since generally the demands of calibration approval cannot be met when further processing the data by PC. When the 8-bit code shall be used, set data exchange to 8 bit when commissioning the terminal. Data exchange between a A810 terminal and an IBM compatible PC requires the 7-bit code (with/without parity bit) or the 8-bit code without parity bit to be used since the UART modules of a PC can transfer a data frame of no more than 10 bits (including start and stop bit).

Recommendation: Always set to 8 bit, no parity unless there are compelling reasons to select some other mode.

4.2.3. Electrical Implementation of the Serial Interfaces

Table 1 shows the assignment of the physical interfaces to a number of standards. Though any physical interface can be connected to any logical device, there is a standard assignment identical with the default configuration when the instrument is supplied. physical interface standard preferred assignment to logical device

4.2.4. Physical Protocol (Handshake)

The physical protocol is for avoiding the loss of data. Each receiving device allows the transmission of characters only when it is able to receive them. When A810 receives a signal 'disable transmission', its transmitter channel will just complete the character currently transmitted. The receiver channel is able to receive another 20 characters after the 'disable transmission' signal has been transmitted to a peripheral device before any loss of data will occur. Each serial interface may operate either without handshake or observing the software protocol. When the software protocol is used, transmission is enabled by the transmitter receiving the XON character (DC1, code 11h) and transmission is disabled by the XOFF character (DC3, code 13h).

4.2.5. Logical Devices

During commissioning, each logical device is allocated a serial interface. Logical devices are printer, remote display unit, PC / SPC, second operating unit and measuring BUS. If there are two logical printers, so two printers can in fact be connected to one terminal.

4.3. Printers

The type A810 terminal is able to communicate with different printers. The type of printer has to be set during commissioning. Traffic between a terminal and a printer depends on the selected mode. This applies to the transmission of certain print commands (Escape sequences). The following printers are supported by a A810 terminal and can be set during commissioning:

• CR/LF

Any printer can be used as a CR/LF printer provided it can process a 7-bit or 8-bit code and control characters Carriage Return (CR, code 0Dh) and Line Feed (LF, code 0Ah). The terminal will not transmit any Escape sequence to a CR/LF printer. Thus no part of the text can be highlighted.

• TM295

The A810 supports the following specific control characters: Line Feed forward/backward, Form

Feed forward/backward, Capital Letters on/off, Switch to German Character Set, Lift Pinch Roller.

• Epson printers of series LX, FX, LQ

The following Standard Escape Sequences are supported which are suitable for other software compatible printers, too: Carriage Return, Line Feed, Form Feed, Wide Font on/off, Bold Font on/off, Narrow Font on/off, Italics on/off, Underline on/off.

• STAR printer SP212, SP312, SP349

The following control characters are supported: Carriage Return, Line Feed, Wide Font on/off, Set to German Character Set, Cut Paper.

Please note that the standard program does not support any teleprinter since there is no reason for a terminal with EU approval to be connected to a teleprinter.

4.4. Remote Display Units

4.4.1. A810 Remote Display Units

Any system compatible remote control and display unit of the A810 will not be used as logical device

'Remote display unit' but instead as logical device 'Second operating unit'. This simplifies the configuration of the interface and enables more functions to be used, e.g. for the commissioning program.

Page



4.4.2. Foreign Remote Display Units

Any A810 terminal can in principle be adapted by the manufacturer to any remote display unit and its protocol. This will be done on customer's demand. Altogether up to 8 different data exchange protocols can be declared and selected by the commissioning program. The remote display can read out either gross, net or tare weight or the value currently on display.

4.5. PC / SPC

Linking an A810 terminal to the serial interface of a computer or a stored-program control unit allows weighing data to be used in data processing or process control. In this case the computer or the control unit is commonly the active party that triggers certain reactions of the terminal by means of a set of declared commands. The default setting of an A810 terminal is such that it will transmit data only in case of error when no request is received.

4.5.1. Acknowledgement Protocol

By issuing an acknowledgement protocol the terminal reports back to the computer whether it has understood a transmitted command. The default setting when a terminal is supplied is such that each command is acknowledged after 25 ms at the latest by character Acknowledge (ACK, code 06h) when it is valid or character Negative Acknowledge (NAK, code 15h) when the command cannot be executed.

Please note that the transmission of character ACK does not prove the meaning of the transmitted data to be correct. The acknowledgement protocol can be changed during in the commissioning program. The same applies to the run time (command ‘PROTOK’).

4.5.2. Structure of a Data Frame

Data frames have identical structures in either direction. Each of them contains the following components: block header data record end of block

The default setting when a terminal is supplied is character STX (code 02h) for the block header and character ETX (code 03h) for the end-of-block code. This declaration can be changed in the commissioning program and during traffic (command 'LINES'). The data record contains the information to be transferred. It consists of a command transmitted to A810 and a data record returned in response.

The characters belonging to a data block shall be transmitted to the terminal within one second, otherwise the terminal will regard the transmission as finished, reply by transmitting NAK and ignore the block.

4.5.3. Remote Control Commands

Each of the remote control command starts with a command number (see Table 3). Depending on the type of command, more parameters may follow. For those commands that request a terminal to transmit a data record, the structure of the returned data record will be explained when describing the command.

A A810 is able to receive several commands directly following one another and to execute them subsequently. The order of the responses need not necessarily coincide with the order of the commands since the response may depend on certain conditions such as dwell.

In the following passage all numbers used in a command are represented as hexadecimal numbers or

ASCII characters. The examples contain only the data records. The block headers and end-of-block codes have to be added in accordance with the block structure used.

4.5.3.1. Keyboard Commands

KEYS_ON Command No 20h Parameters: none

The entire keyboard of a terminal is re-enabled (made active) after the command

KEYS_OFF. This applies also to a second operating unit possibly connected. This is the on-condition.

KEYS_OFF Command No 21h Parameters: none

The entire keyboard of a terminal is disabled (made inactive). This applies also to a second operating unit possibly connected but not to a key function activated via parallel interface.

KEYFUNCT Command No 24h Parameters: key code

This command contains the code of a key (see Table 4

) as its parameter. It has the same effect as pressing the respective key on the keyboard.

This command can be used to remote-control a function of the terminal that can be triggered by a single keystroke. Input operations consisting of key sequences (e.g. input of a coefficient) cannot be implemented this way, there are other commands for this purpose.

S_KEYON

Example: ‘$ A'

Command No 35h trigger print function

Parameters: none

After this command has been received, any keystroke at the terminal is transmitted in a keycode data record till command S_KEYOFF will shut down this mode.

Returned data record:

* identifier

* code

Example:

'C' for keycode keycode according to Table 4

'C B' key 'Set to zero' has been pressed

S_KEYOFF Command No 36h Parameters: none

The mode of operation triggered by S_KEYON is shut down.

S_INPUT Command No 37h Parameters: range of values

The terminal is switched to mode Input of numbers.

Parameters:

* identifier 'K' for answer code

A810 will transmit ACK and NAK enclosed in a block frame made up of STX and

ETX.

The command takes effect immediately, so command PROTOK is acknowledged already by the newly set protocol. If needed at all, this command should always open the exchange of data.

ADDRESS Command No 39h Parameter: device address

The interconnection of several terminals in a TTY ring or on an RS485 BUS requires that exactly one device is addressed at any time. Immediately after power-on the device having the address '0' is active. Command ADDRESS is for selecting the device the address of which is the parameter transmitted whereas all the other devices in the ring are disabled.

Example: '95' enable device with address 5

LINES Command No 3Ah Parameter: block structure

The command LINES determines the structure of a data block by defining its header and end. The relevant parameters in the Set-up will be overwritten. This parameter can be used to match the data protocol of the terminal with the conventions of the program running on the computer. The following modes can be set:

Parameter block header end of block

'0' STX

'1' STX

'2' STX

'3' STX

'4'

'5'

'6'

'7'

ETX

CR

ETX

CR

CR

LF

When a protocol approved for calibration is used, only parameters '0' to '3' are permitted since the protocol requires characters STX and ETX.

4.5.3.5. Miscellaneous Command

TERMINAL Command No 34h Parameters: none

Command TERMINAL can be used for running an A810 terminal as a second operating unit for the input and output of characters in connection with a PC or an SPC, respectively. If data exchange approved for calibration has been set during setup, the terminal will not execute this command. After command TERMINAL has been transferred all characters contained in a data block are read out by the display of the A810 as far as the display is able to do so. Vice versa the A810 transmits each character entered directly by keyboard to the PC/SPC. The Terminal-mode of operation is shut down by transferring the end-of-block character (ETX) to the terminal.

S_CONFIG Command No 41h Parameters: none

After receiving this command, the terminal returns a string of characters containing the program version number, the date of release, and a few code bytes identifying the translation mode of the program. The length of the transmitted data block is variable.


* program release No identifier

* program release date

* configuration byte 1

This command is to set DA-converter to a voltage level.

Parameter 0 is equal to a voltage of 0V resp. a current of 0mA and the maximum of 4095

(FFFh) is equal to a voltage of 10V resp. a current of 20mA.

Example: ‘N2048’ output of 5V resp. 10mA at DA-converter

4.5.4. Behaviour in case of trouble

In normal conditions the terminal transmits data on request whereas in case of trouble an error message resulting in the shut-down of the scale program is transmitted compulsorily at the time when it is read out by the display. Acknowledge the error message either by pressing key 'Test' or by transmitting key code

'C' via PC interface.

Error data record:

* identifier

* number

'F' for error

6.1. Calibration procedure

1: Release Calibration Lock (CAL Switch = ON) at rear panel of A810.

2: Select primary measurement unit “MU” 3.1.1.2.

- The calibration is done with this unit.

- This unit is shown on display after each restart of A810.

3: Select stablility settings 3.1.3

- Adjust ADC settings deponding on your environment

- Adjust filter settings so that sign “STABLE” is illuminated (“StAN” 3.1.1.11 and “StAR”

3.1.1.12 at page 27) during weighing.

4: Do scaling 3.1.2

Notice:

Fullscale (FS) = Divisions (Dn) * Verified Scale Interval (VS)

Scaling is done for selected measurement unit “MU” (kg, To, Gr, Lb, oz, N, kN or FU).

(Scaling and calibrating of Free Unit “FU” overwrites “KG”-calibration and scaling.)

To ensure that your device is legal-for-trade set division “Dn” (3.1.2.1.1) lower or equal 10000.

- Division

Select desired scale intervals over fullscale range between 10 and 100000 at point 3.1.2.1.1

- Verified scale interval (VS)

Select lowest interval of the scale at point 3.1.2.1.2. This is the finest resolution.

(FS)

The shown value at point 3.1.2.1.3 is the result of division “Dn” times Verified Scale Interval

“VS” plus one “VS”. The operator can see the Fullscale and its resolution at a glance.

- unload the loadcell and do a Zero Calibration

- put testweight on loadcell and register this weight to A810

Note:

This weight should be more than 20% of Fullscale for accuracy!

- In case of a non-linear loadcell the operator can set up to six additional calibration

points for adjustment.

6: Close calibration lock (CAL Switch = OFF) and restart the system.

Page



Example

:

100kg

Resolution 0.01kg

Menu

- Stability settings are done according to operators environment. set

- “Dn” = 100kg / 0.01kg = 10000

- set “Dn” to 10000 set 0.01

Æ

A810 is legal-for-trade for confirmation of correctly set parameters: “FS” shows 100.01kg

3.1.2.1.1

3.1.2.1.3

Additional settings:

When operator wants to switch between measurement units in weighing mode these units have to be scaled as well. Be aware that both Fullscale values have to have the same weight.

3.1.2

- unload loadcell and do a Zero Calibration

- put testweight of more than 20kg (>20% of FS) on and enter this weight

3.1.4.1.1

Additional settings:

When the loadcell is non-linear, the operator can set additional calibration points.

In that example the testweight is 50kg. A810 would show approx. 45kg.

To adjust this loadcell error, put testweight on and enter 50.00kg in

3.1.4.2 menu “AddP”.

Now A810 shows correct weight. mV / V

6.2. Theoretical calibration

Theoretical calibration is used for calibration without balance weight. It is possible to enter a known input ratio of an load cell to A810. This procedure is not as accurate as calibration with balance weight because tolerances of components influence the result.

When operator knows the input ratio of a load cell and wants to replace the weighing controller, he should have marked out these values before. These values could be for example:

0.00239mV/V at Zero point and

2.15267mV/V at nominal load.

(from 3.1.17.4 at page 66)

(from 3.1.17.5 at page 66)

After replacing the weighing controller, these two input ratios are entered to A810. At first the known input ratio at Zero point of load cell is entered at point 3.1.4.3. After that the known input ratio at Fullscale of load cell is entered. A810 is now calibrated at these two points.

When you do only a theoretical calibration at Zero point, weighing function is moved parallel to previous weighing function.

When you are using A810 and load-cell out of the box and you want to do theoretical calibration, the procedure is as follows:

enter “0.00000” at Zero point (3.1.4.3 at page 35)

enter mV/V-ratio delivered with your load-cell at nominal load

return to weighing mode and A810 shows value different from zero

enter setup mode again

do zero with unloaded cell (submenu “Calibration” 3.1.5.1.1 at page 34)

return back to weighing mode and A810 shows zero.

6.3. Simple Comparison Mode – Feeding Weighing e.g. 1


Page

97


Settings for this example:

Simple Comparison Mode is activated setting parameter “SMS” in submenu “control” (3.1.6 at page 39)

OFF

.

Feeding is activated setting parameter “Fd-Con” in submenu “control” (3.1.6 at page 39) to “0”.

The weighing value compared at Near Zero (“NZ”) can be Gross or Net, selected at 3.1.7.1 at page 41.

In this case parameter is set to “1“: compare with net weight”.

The weighing value compared with Final, Over and Under (“FOU-CMD”) can be Gross or Net, selected at

3.1.7.2 at page 41.


In Simple Comparison Mode the Over, Go and Under comparison is done due to the settings of

“OUC-MD” in menu 3.1.7.4 at page 42.

In this case parameter is set to “2“: compare when complete output is ON”.

When set this parameter to 3, A810 will not change any outputs, weighing value or indicators during

“Complete Output Time”.

The “Complete Output” signal is ON due to the setting of “CSO-MD” in menu 3.1.6.3 at page 39.

In this case parameter is set to “0“: judging time is expired”.

Conditions:

- When weighing value ≤ set value of Near Zero, the Near Zero output turns on.

- When weighing value ≥ Final – Set Point1, the SP1 output signal turns off.


- When weighing value ≥ Final – CPS, the CPS output signal turns off.

- When weighing value ≤ Final – Under, the Under output signal turns on when complete signal is active.

- When weighing value ≥ Final + Over, the Over output signal turns on when complete signal is active.

- When Final – Under ≤ weighing value ≤ Final + Over, the Go output signal turns on when complete signal is active.

Timers: t1: Comparison Iinhibited Time “CITI” – set in 3.1.7.6 at page 42 t2: Judging Time “JTI” – set in 3.1.7.7 at page 42 t3: Complete Output Time “COTI” – set in 3.1.7.8 at page 43

A full “Simple Comparison Mode” is restarted after weighing value felt below of ¼ of Fullscale. Otherwise the “Complete Output” signal is not activated.

Discharging is activated setting parameter “Fd-Con” in submenu “control” (3.1.6 at page 39) to “1”.

Upper and Lower Limit has to be compared with Gross weight. Parameter “ULL-CMD” in submenu

“COMP” (3.1.7 at page 41) is set to “0”.




3.1.7.2 at page 41.







The “Complete Output” signal is ON due to the setting of “CSO-MD” in menu 3.1.6.3 at page 39 after the

Stable condition is detected.

In this case parameter is set to “2“: after CPS is set, stable is set or judging time is expired”.

Conditions:










Main differences between “Feeding Weighing” and “Discharging Weighing”:

- “Fd-Con” is set to “1”

- “ULL-CMD” has to be “0”

- “FOU-CMD” has to be “1”

Page



6.6. Sequence Mode


Page

103


Sequence Mode is activated setting parameter “SMS” in submenu “control” 3.1.6.1 at page 39 to ON.

Wheighing sequence starts at the rising edge of Start signal; SP1, SP2, SP3 turn on.

In Sequence Mode the Over, Go and Under comparison is always done when the “Complete output” is

ON

and Judging Count “JC” 3.1.8.2 at page 44 is not set to “0“.


3.1.7.2 at page 41.

In this case parameter is set to “1“: compare with net weight”. In this case, Net weight is set to zero at

“start”.

When setting “FOU-CMD” to “0“: compare with gross weight”, then gross weight is set to zero at “start”.

Setting of parameter “OUC-MD” in menu 3.1.7.4 at page 42 has no affect! Internal treatment is like set to

“3”.

The weighing value compared at Near Zero (”NZ”) can be Gross or Net, selected at 3.1.7.1 at page 41.


Conditions:





- When weighing value ≤ Final – Under, the Under output signal turns on.

- When weighing value ≥ Final + Over, the Over output signal turns on.

- When Final – Under ≤ weighing value ≤ Final + Over, the Go output signal turns on.

Timers: t1: Comparison Iinhibited Time “CITI” – set in 3.1.7.6 at page 42 t2: Judging Time “JTI” – set in 3.1.7.7 at page 42 t3: Complete Output Time – set in 3.1.7.8 at page 43

Page



6.7. Sequence Mode without Judgement

Entering a Judging Count of 0 in “JC” (3.1.8.2 in submenu “SEQU” at page 44) disables Over, Under and

Go comparison during Complete Output Time “CTI”.

When SP3/CPS turns OFF, Complete signal turns ON immediately.

Timers: t1: Comparison Inhibited Time “CITI” – set in 3.1.7.6 at page 42 t3: Complete Output Time – set in 3.1.7.8 at page 43

In this example Judging Timer “JTI” set in 3.1.7.7 at page 42 is set to zero.


Page

105


6.8. Sequence Mode with Adjust Feeding

Enable Adjust Feeding in “AdFd” (3.1.8.3 in submenu “SEQU”).

In Sequence Mode the Over / Under comparison is done when the Complete output is ON.

Timer “CFT” re-opens SP3 for a certain time to adjust final weight.

Timers: t1: Comparison Inhibited Time “CITI” – set in 3.1.7.6 at page 42 t2: Judging Time “JTI” – set in 3.1.7.7 at page 42 t3: Complete Output Time ”COTI” – set in 3.1.7.8 at page 43 t4: Compensation Feeding Time “CFT” – set in 3.2.3.2.15 at page 71

Page



6.9. Auto Free Fall Compensation

Auto Free Fall Compensation adjust the amount of feeded ingredient in “Sequence Mode” to automatically reduce weighing errors, reaching Final weight as close as possible.

For that procedure

- AFFC-CN completed cycles are recorded

- differences (error) between actual weight and Final weight is calculated each time

- average the errors after AFFC-CN cycles

- this average is multiplied by CPS-CE for weighting

- result is added to CPS value.

Example:

7.3. Description of States of Error

When an error occurs, the terminal reads out an error message in place of weight. Apart from underload and underload, every error message has to be acknowledged by pressing key 'Set to zero'. Depending on the type of error, the terminal will either restart or continue its operation. Trace the cause of the error and eliminate it whenever it occurs one more time. 7.3 shows all possible error messages as well as possible sources of error.
