1. INTRODUCTION

1.1 General

The A200E instrument is a microprocessor based weight amplifier and indicator.

When fitted with SW release 1.53e it can be configured to handle setpoint or simple batch control.

In set point mode the 3+8 relay operation is based on simple threshold.

In batch mode the unit can handle the charge of up to 3 components (double speed) and the

discahrge of one component (dual speed).

In set point mode the unit has added the load peak function (gross weight)

It was designed to connected to a maximum of 8 load cells (350 Ωbridge), connected in parallel.

The keyboard can be used to carry out all the programming, configuration and calibration functions.

A series of display messages guides the operator through all the phases.

A series of options sets up the instrument for the main functions related to electronic weighing.

2. INSTRUMENT OPERATIONS

2.1 Turning on the instrument

When the instrument is turned on, the primary display indicates the following:

−−−−−

and the auxiliary display indicates the following, at intervals of about two seconds:

A D O S S r L

A 2 0 0 E

2.1.1 Load cell signal averaging

Starting with SW rev 1.50 a new load cell signal averaging method have been introduced (FIR

filters). This method is based upon Digital Signal Processing (DSP) methodologies and is useful

when the load cell signal has a large amount of harmonics (due for instance to mixers, agitators or

similar).

In configuration phase user can select one of three classic ( mobile average) and five DSP filters.

First type of filter has a fester response time but are less efficient against disturbance and can be

used when fast changing loads have to be detected.

Second type of filter are very efficient against noise and disturbances (having a higher filter effect)

but have of course a higher response time.

In both cases higher filter coefficient corresponds to higher filtering effect and higher response

time.

As example the following graphic shows the answer to a step changing load signal as function of

different filters.

As can be noticed FIR 1 has a response time of about 0.2 seconds and FIR 5 has a response time of

about 2.5 second.

2.2 Display indication

2.2.1 Primary display

Under normal operating condition the display shows the value of weight, using the following criteria:

•leading zeroes will presented as blank

•if the value is greater then 99999 only the 5 less significant digit are displayed and the display

will blink to indicate that there is another digit, which value is 1, not displayed (please note that

during configuration is not possible to set any combination of graduation and resolution which

leads to results higher than 199999)

•the polarity “minus” (in case of negative values) is indicated in the leftmost digit

•if the negative value is composed of five digits (for example -32420), the leftmost digit will

show alternatively the “minus” and the fifth digit value.

•if the negative value is composed of six digits only the 5 less significant digit are displayed and

the display will blink to indicate that there is another digit, which value is 1, not displayed. The

leftmost digit will show alternatively the “minus” and the fifth digit value.

Indication limits are the following:

lower limit: - 20% of full scale

higher limit: 120% of full scale

if the weight is under the lower limit the following will be displayed:

−−U L −

if the weight is over the upper limit (or if the load cell signal is higher than 20 mV the following

will be displayed:

−−O L −

2.2.2 Auxiliary display

Under normal operating conditions and with the instrument in GROSS, the auxiliary display

indicates the current time, in the format hours-minutes-seconds:

0 9 : 1 1 : 5 5

Press 0on the display to indicate the current date, in the format day-month-year, for two seconds:

1 5 - 0 5 - 9 6

Under normal operating conditions and with the instrument in NET, the auxiliary display shows the

value of the TARE with two alternating messages:

T A R E 1

1 2 3 . 4

In the configuration and calibration phase, the auxiliary display is used to guide the operator in

carrying out the functions.

In batch mode the display shows the batch status.
