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).
This menu contains the basic adjustments affecting the ability of the scale to be approved for calibration.
The adjustment might be carried out before calibration.

3.1.3.3. ADC sampling rate “SR”
Set in terms of preset values for standard
sampling rate and corresponds to the
number of samples per second
achieved by the ADC.
In connection to the filter settings the

application. Higher value is faster.
default setting: 50 samples / sec
Note: When SR = 100, “StAN” (3.1.1.11) is set automatically to 100 when “StAN” is greater than 100.
When SR = 200, “StAN” (3.1.1.11) is set automatically to 10 when “StAN” is greater than 10.
When SR = 400, “StAN” (3.1.1.11) is set automatically to 2 when “StAN” is greater than 2.
This menu allows the operator to perform either a practical or a theoretical calibration. During the practical
calibration a desired load has to be applied a zero / full scale span calibration by using of at least two
points. Additional entered points will increase the accuracy.
The theoretical calibration allows to enter the known input voltage ratios but it will not reach the accuracy
of a practical calibration due to tolerances of electronic components.

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.
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 printer
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.
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.
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.
Example: ‘$ A' trigger print function
S_KEYON Command No 35h 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 'C' for keycode
* code keycode according to Table 4
Example: '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
* character is indicated by 1
* identifier 'M' for minimum of input number range
* number ASCII string (integer)
* identifier 'X' for maximum of input number range
* number ASCII string (integer)
* identifier 'P' for decimal point (number of trailing digits)
* number ASCII character {'0' to '4'}
The identifier and the decimal point indicated by the display unit of the terminal are just
for the operator's information, they have no effect whatsoever on the value of the entered
number. The display will furthermore indicate '0' for the last digit which will be shifted
when a numeral is entered. Press ‘TARE’ to correct a digit and press ‘ENT’ to conclude
the input. When the number entered is outside the preset range of numbers, the input
routine cannot be left but is repeated. After a valid number has been entered, the terminal
will respond and return to the display of weight.
Example: '7KLM20X100P1' Identifier 'L', Min 2.0, Max 10.0
Returned data record:
* identifier W for input of number
* number ASCII string (integer)
Example: command from PC/SPS '7KLM20X100P1'
the display reads out: L .0
input of 7 5 ‘Ret’ L 7.5
response by A810 'W75'
4.5.3.2. Commands for Weighing Operations
S_D_STI Command No 25h Parameters: none
The weight value indicated by the display (gross, net or tare) is transmitted one single
time as soon as the display is updated after the dwell condition has been met.
Returned data record:
* status byte condition of load cell, bit code see Table 2

by the terminal has the same resolutions as the value on display (default condition).
Parameter '1' increases the resolution of the transferred data records 10 times. The
command will not be executed when the data transfer mode approved for calibration has
been declared during commissioning.
SET_TARA Command No 2Bh Parameter: tare weight
The parameter to be transferred as an ASCII string is the value of the tare weight to be
set and its unit is the basic unit of the terminal. Subsequently the terminal will switch to
the display of net weight and the LED of sign 'TARE' will be active. Please note that the
weight is represented in the unit of measurement currently enabled. When you run a
terminal with several units of measurement, check the unit of measurement currently
used by beforehand reading out a weight value.
Example: '+10.35' set tare memory to 10,35
E_PARAM Command No 2Ch Parameters: scale parameters
Parameters filter coefficient, zero tracing, and dwell range are transmitted to the terminal.
Always follow this order and do not omit any parameter. You are allowed, however, to
omit a parameter not followed by another one. The command will not be executed when
the data transfer mode approved for calibration has been declared during commissioning.

Parameters resolution, count-by step, filter coefficient, and status of the zero-tracing
facility of the current channel are transmitted. The dwell range is transmitted as well
except for the compound channel.
When a scale has a partial weighing range (multi-range scale), the resolution and countby step of the partial weighing range are also included in the data record.
Returned data record (scale without partial weighing range):

in partial weighing range, count-by step 0.002*unit in partial range, filter
90, zero tracing facility active, dwell range 1d
E_ME Command No 45h Parameter: number of unit of measurement
This is to set the unit of measurement by transmitting its number as a parameter. When
doing so, the numbers ‘0’ to ‘6’ stand for the units of measurement kg, t, g, lb, oz, N, and
KN. The command is executed only when the selected unit of measurement has been
declared during set-up.
This parameter is made up of up to 8 ASCII characters representing a number between 0
and 10000000. This number will be used as serial number as from the next printing
operation provided it does not fall outside the range of serial numbers declared during
setup.
Example: '1123' set serial number to 123
S_LFDNR Command No 32h Parameters: none
An ASCII string is transmitted representing the serial number to be used for the next
printout.
Returned data record:
* identifier 'c' for serial / consecutive number
* number ASCII string of number
Example: 'c456' use serial number 456
E_DBILD Command No 33h Parameter: print image
Command E_DBILD requires 8 bit data exchange. This command is for uploading a userspecific print image to the RAM of the terminal or for disabling a print image, respectively.
Add the print-image identifier 'U' after the Command No if you want to upload a print
image. After that you may add up to 1000 characters which will form the print image. In
doing so you may use any printable ASCII code as well as the codes of place holders and
control functions. For the syntax for drawing up a print image please refer to chapter
'Commissioning, Scaling', paragraph 'Structure of a Print Image'. There you will find the
tables containing the declared codes. Transmit this command without any parameter if
you want to disable a print image. The following printout will then be based on the ROMresident print image.
Example: 33h 55h ;command number, identifier print image
FFh 90h ;carriage return
FFh 91h FFh 91h ;2 times line feed
FFh 93h ;wide font on
54h 65h 73h 74h ;'Test'
FFh 94h ;wide font off
FFh 90h FFh 91h ;carriage return, line feed
FFh B0h ;fixed text 'gross'
FFh 80h 0Ch ;gross weight, 12 digits
FFh F0h ;end
DR_PCON Command No 3Bh Parameters: none
This command has the effect that any character transmitted to the printer is concurrently
transmitted to the PC interface. For this you have to declare a printer as a logical device
during setup.
Returned data record:
* identifier 'DRU' for printer data record
* string of ASCII and control characters according to print image and declared type of
printer (example applies to CR/LF printer)
The mode of operation set by means of DR_PCON is shut down.
E_DBOFFS Command No 42h Parameters: offset values
This command allows to change the displacement of the print image to the right and to
the bottom and the following space lines as declared during Set-up.
Parameters:
* identifier 'l' for space lines in front of the print image
* number between 0 and 99, number of space lines in front of print image
* identifier 'c' for spaces in front of each line
* number between 0 and 99, number of spaces in front of each line
* identifier 'f' for space lines behind the print image
* number between 0 and 99, number of space lines behind print image
Example: 'l5c12f2' 5 space lines in front of print image, 12 spaces
in front of each line, 2 space lines after print
image
PRINT Command No 43h Parameters: printdata
This command is for direct printing to logical printer 1. Printdata can contain printable
characters as well as ESC-sequencies. A binary zero is interpreted as end of datastream.
Length of printdata is restricted to 1000 characters.
Example: 'CA810' Text ‘A810’ will be printed directly.
This command is for setting the product-code (0…255) of A810.These codes are printed
to alibi-memory or physical printer.
Example: 'R100' Setting product-code to 100.
S_PCODE Command 53h Parameters: none
This command reads out product-code.
Example received data: 'C100'
4.5.3.4. Commands for Data Protocol
PROTOK Command No 38h Parameters: Acknowledge protocol
This command is for matching the acknowledge protocol with the requirements of the
other station. The relevant setup parameter will be overwritten. The command is followed
by an ASCII character selecting the protocol. The following modes can be set:
'0' standard protocol, acknowledge characters ACK and NAK are transmitted
according to DIN 66019.
'1' A810 will not transmit ACK and NAK.
'2' 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:
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.
Returned data record:
* program release No 81.xx
* identifier '/'
* program release date dd.mm.yy
* configuration byte 1
* configuration byte 2
Meaning of configuration byte 1
Bit0: 0=special software 1=standard program
Bit1: 0=function keyboard only 1=additional keyboard
Bit2: always 1
Bit3: always 1
Bit4: 0= 1=compound scale
Bit5: 0= 1=scale with partial range
Bit6: always 1
Meaning of configuration byte 2
Bit0: 0= 1=analog interface active
Bit1: always 1
Bit2: always 1
Bit3: always 1
Bit4: always 0
Bit5: always 1
Bit6: 0= 1=parallel interface active
Example: '10.01/02.09.06O/' standard program 810.01 dated Sept. 2
1-channel A810 with additional keyboard and
analog interface
CALL_FU Command No 47h Parameters: # of operating function, keycode
This command is to call an operating function directly. Additional keycodes can be added
as well.
Example: ‘G*311206K’ call function 42 (‘*’ - set date), enter 31.12.06
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 'F' for error
* number ASCII string (max. 2 digits)
Example: 'F13' Breakdown of positive supply voltage ADC 1

5.2. Features / Basic functions
Theoretical Calibration
In addition to the capability of adjusting the A810 by using calibrating weight a theoretical calibration via
the characteristic value and rated load of the load cells is also possible.
Auto free fall compensation
The automatic free fall compensation (AFFC) provides closer tolerance and better
accuracy in batching application.
Selfcheck and Watchdog
To insure function and reliability of the complete system well proofed self check procedures and a
watchdog function are provided.
Accumulation Function
The A810 accumulation function continuously updates the material throughput and monitors the total sum
and the counts for each code group separately.
Feeding-/ Discharging weighing
The A810 allows an accurate feeding or discharging process controlled by a set of weighing control
parameters.
For comparison there are the simple comparison and the sequence mode selectable.
‘dIAG’ diagnostics yes no

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 (Dn)
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.
- Fullscale (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.
5: Calibration 3.1.4
- 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.
- Stability settings are done according to operators environment.
- set “MU” to “kg” 3.1.1.2
- “Dn” = 100kg / 0.01kg = 10000
set “Dn” to 10000 Æ A810 is legal-for-trade 3.1.2.1.1
- set “VS” = 0.01 3.1.2.1.2
- for confirmation of correctly set parameters: “FS” shows 100.01kg 3.1.2.1.3
Additional settings:
When operator wants to switch between measurement units in 3.1.2
weighing mode these units have to be scaled as well. Be aware
that both Fullscale values have to have the same weight.
- unload loadcell and do a Zero Calibration 3.1.4.1.1
- put testweight of more than 20kg (>20% of FS) on and enter this weight
to A810 3.1.4.1.2
- do calibration 3.1.4.1.2
Additional settings:
When the loadcell is non-linear, the operator can set additional 3.1.4.2
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
menu “AddP”.
Now A810 shows correct weight.
- close Calibration Lock (CAL Switch = OFF) and restart A810.
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 (from 3.1.17.4 at page 66)
2.15267mV/V at nominal load. (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.
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 this case parameter is set to “1“: compare with net weight”.
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 – Set Point2, the SP2 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.
