Thank You!
Thank you for purchase A.S.T. products!
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.

1.10.22 (May 11): signal output B21 used in sequence-mode; generation of Err109 due to
missing confirmation signal at input pins D18 or D19 (with user function
“230” associated); detailed description of signal input D18/19 at page 65;
change of picture “PC-Interface” at page 88; new parameter “SPFix” in
menu “DAC” for constant analog output at setpoints SP1, SP2 and CPS
1.10-21 (November 10): Interface: USB as option
1.10-20 (September 10): graphics of frontdesign and rear-panel changed due to constructive
reasons
1.10-19 (January 10): due to change of processor, sample rate of 400/s is selectable
(Firmware-Version V.32)
1.10-18 (June 09): due to Firmware-Update to V.31 default parameter dISP-R changed
(faster display rate)
1.10-17 (June 09): due to Firmware-Update to V.30 parameter dISP-R added (display rate
selectable)
1.10-16 (May 08): description Err 129 added
1.10-15 (March 08): refresh rate of I/O added
1.10-14 (January 08): additional operating functions added
1.10-13 (November 07): description of “dAC” changed

The front panel contains a 7 digit numeric display, a two digit alphanumeric display, a multiple status
display and 16 key membrane pad.
Legal-for-trade weighing parameter information is available in a separate window (Descriptive marking).
1.1.1. Numeric Display
The seven digit large size display allows showing a six digit weighing value and an additional plus / minus
character. This display is used for weighing values like Gross, Net, Tare, accumulation values and setup
values as well as Error messages.
1.1.2. Unit Display
This two digit unit display is used for units in weighing mode and for alphanumeric information in setting
mode.
1.1.3. Status display
SP3 : Turns on, if the weighing value has reached “FINAL” – “CPS” and the desired output
signal at the rear panel is active on.
SP2 : Turns on, if the weighing value has reached “FINAL” - “SetPoint2” and the desired
output signal at the rear panel is active on.
SP1 : Turns on, if the weighing value has reached “FINAL” - “SetPoint1” and the desired
output signal at the rear panel is active on.
KEY : Turns on, if the calibration lock is enabled.
ZT : Turns on, if zero tracking is in operation.
ZALM : Starts flashing if zero drift exceeds the Digital Zero limit.

Relay outputs (connector B) and Opto inputs (connector D) can either be with power (active) or neutral
(passiv) depending on interal jumper position on mainboard. Both Input and Output connectors are
separated into four groups. Each group contains four signals with dedicated COM. By setting each
individual jumper’s position to decide each group whether the I/O are with power or neutral.

2.3. Control Input Signals
- Gross / Net (G/N) (pin D4)
(edge triggered)
Display value is switched between Gross and Net by pressing key or by changing input
D4.
When input signal is shorted to COM (OFFÆON) Net weight is displayed.
When input signal is opened to COM (ONÆOFF) Gross weight is displayed.
Pressing dedicated key will always toggle between Net and Gross, independent of input signal.
-Digital Zero (DZ) (pin D5)
(edge triggered)
The Gross weight is set to zero by pressing key or by shorten input D5 to COM
(OFFÆON).
When “ZALM” is illuminated, Digital Zero Regulation Value is exceeded and no setting to zero can
be done. Refer to 3.1.1.3 and 3.1.1.4 at page 25 for zero settings.
- Tare substraction (TARE) (pin D6)
(edge triggered)
The Net weight is set to zero by pressing key or by shorten input D6 to COM (OFFÆON).
Taring depends on its mode (3.1.1.10 at page 26) and its limit (3.1.1.9 at page 26).
- Tare Reset (TARE long press, when is illuminated )
(pinD7)
(edge triggered)
The Net weight is brought to Gross weight by pressing key and then key.
After that is illuminated. Reset Taring weight by pressing for longer then 1s or by
shorten input D7 to COM (OFFÆON).
- Hold or Judgement (pin D8)
(level triggered)
The weighing value is hold by shorten input D8 to COM (OFFÆON) and “HOLD” is illuminated.
Over/Go/Under (3.1.7.4 at page 42) and Upper/Lower (3.1.7.5 at page 42) Limit have to be both
set to “0”.
At other settings the input switches to “Judgement”.
Over/Go/Under comparison mode (“OUC-MD”, 3.1.7.4 at page 42):
0: compare always
1: compare when judging input is ON
2: compare when complete output is ON
3: compare when complete output is ON
and weight will be hold during that time
Note: “Hold mode” is only available in Simple Comparison mode.

- Feed/ Discharge (pin D9)
(level triggered)
Feed or Discharge is accessed by shorten(Discharge) or open (Feed) input D9 to COM.
“Fd-Con” (3.1.6.2 in submenu “control” at page 39 has to be “2”).
0: feeding
1: discharge
2: external control
During Dischrage mode, “Upper/ Lower Limits” has to be compared with Gross weight (“ULL-
CMD” 3.1.7.3 set to “0”) and “Final/Over/Under” has to be ompared with Net weight (“FOU-CMD”
3.1.7.2 set to “1”).
Note: “Discharge mode” is only available in Simple Comparison mode.
- Start (pinD10)
(edge triggered)
During “Sequence mode” shorten input D10 to COM will start sequence cycle.
- Stop (pinD11)
(edge triggered, level triggered)
During “Sequence mode” shorten input D11 to COM will stop sequence cycle or clears sequence
errors.
Refer to 6.6 “Sequence mode” at page 103 for more detail.
- Start accumulation (pin D16)
(edge triggered)
Accumulation is done when shorten input D16 to COM (OFFÆON) and at rising edge of
“Complete output” signal. FOUC-MD (3.1.7.2 at page 41) has to be set to 0 (gross) or 1 (net).
“Func” + “3”: shows sum of accumulated weight
“Func” + “4”: shows counter of accumulated weight cycles
- Clear accumulation (pin D17)
(edge triggered)
Accumulation Counter and weight value is cleared when shorten input D17 to COM (OFFÆON)
for more than 3 seconds. For confirmation “del Acc” will be displayed.
- User Function I (pin D18)
(edge triggered)
This user defined function is activated when shorten input D18 to COM (OFFÆON).
Refer to 3.1.16.1 at page 64.

Manual of Weighing Controller A 810
Page 18 A.S.T. Angewandte SYSTEM-TECHNIK GmbH Dresden
- User Function II (pin D19)
(edge triggered)
This user defined function is activated when shorten input D19 to COM (OFFÆON).
Refer to 3.1.16.2 at page 64.
- Code selection (pins D20-23)
(level triggered)
This binary input select active codeset when inputs are shortened to COM. “External Code”
(3.2.3.2 at page 67) has to be “ON”.
Any selected codeset greater than 9 will generate “Err110”.
D23 is low-bit and D20 is high-bit.
Example: binary presentation
Selection of codeset 5: shorten D23 to COM (code N°1); 1
open D22 to COM (code N°2); 0
shorten D21 to COM (code N°4); 1
open D20 to COM (code N°8); 0
