See section 9 for details of the RS-232 Interface.

3.4.3 CONNECTION OF RELAY DRIVERS

The output to drive external relays is on the circuit board inside the enclosure. To gain access you must remove the 6 screws securing the front to the rear of the case. Pass the wires for the relays through the grommet on the rear panel. The wires will connect to the PCB using the terminal strip P1.

4.0 KEY DESCRIPTIONS

[>Z/T<]

If near zero, Sets the zero point for all subsequent weighing. The display shows zero.

Tares the scale. Stores the weight currently on the scale as tare value, subtracts the tare value from the gross weight and shows the results

A secondary function, is of “Enter” key used when setting up the value for the Parameters.

[Pcs/] Selects parts counting. Used to set the sample quantities

while parts counting. A secondary function,  is of incrementing the active digit when setting a value for Parameters.

[Unit/]

Selects the weighing unit to be displayed from those which are enabled. See parameter S1 in section 7.4.

A secondary function,  is to move the active/flashing digit to the left when setting values for Parameters.

[Func/C]

[Print/M+/Esc]

[O/I]

5.0 DISPLAYS

Selects the Functions of the scale. If the scale is weighing, it will select parts counting. If it is not in weighing mode, it will return the user to weighing.

A secondary function (C) is to act as a clear key when setting values for Parameters.

Sends the results to a PC or a Printer using the RS-232 interface. It also adds the value to the accumulation memory if the accumulation function is not automatic.

A secondary function (ESC) is to return to normal operation when the scale is in a Parameter setting mode.

To switch on and switch off the indicator. The AE402 will store the weighing unit in use and the check weighing values currently in memory when power is off.

The LCD display will show a value and a unit to the right of the digits. In addition the LED’s above the display will show when a weight is below or above check-weighing limits.

Other symbols will show when a weight has been tared (NET) the scale is at zero and stable, if a value has been stored in memory or when the animal weighing function has been enabled. A battery symbols will show the state of charge of the internal battery.

6.0 OPERATION

6.1 ZEROING THE DISPLAY

• You can press the [Z/T] key at any time to set the zero point. This will

usually be necessary when the platform is empty. When the zero point is obtained the display will show an indicator for zero.

• The scale has an automatic re-zeroing function to account for minor

drifting or accumulation of material on the platform. However you may need to press the [Z/T] key to rezero the scale if small amounts of weight are shown when the platform is empty.

6.2 TARING

• Zero the scale by pressing the [Z/T] key if necessary. The “ZERO”

indicator will be ON.

• Place a container on the platform, a value for its weight will be

displayed.

• Press the [Z/T] key to tare the scale. The weight that was displayed is

stored as the tare value and that value is subtracted from the display, leaving zero on the display. The “NET indicator will be ON. As a product is added only the net weight of the product will be shown. The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.

• When the container is removed a negative value will be shown. If the

scale was tared just before removing the container this value is the gross weight of the container plus all products that was removed. The “ZERO” indicator will be on to indicate that the platform is back to the same condition as it was when zero was last set.

• To delete a Tare value, press [Z/T] when the pan is empty.

6.3 WEIGHING A SAMPLE

To determine the weight of a sample, first tare the empty container if it is to be used and then place the sample in the container. The display will show the net weight of the sample and the units of weight currently in use.

6.4 PARTS COUNTING

If parts counting is enabled, See section 7.4, it is possible to count parts using a sample of the parts to determine average piece weight.

• Before starting, tare the weight of any container that may be used,

leaving the empty container on the scale. Place a known number of samples in the container, if used. The number should match the options for parts counting, i.e., 10, 20, 50, 100 or 200 pieces.

• When the scale is showing weight, pressing the [Pcs/] key will start

the parts counting function.

• The scale will show “P 10” asking for a sample size of 10 parts. Change

the sample size to the desired quantity by pressing the [Pcs/] key. It will cycle through the options: 10, 20, 50, 100, 200 and back to 10.

• Press the [Z/T] key again when the number matches the number of

parts used as the sample. As more weight is added the display will show the number of parts (Pcs).

• Pressing the [Unit/] key will display the unit weight (g/pcs), pressing

it second time will display the net weight (pcs and kg) and the third time, it will be the count again (pcs).

• Press the [Pcs/] key to return to normal weighing. Press the [Pcs/]

key again to start counting a different sample.

6.5 CHECK-WEIGHING

Check-weighing is a procedure to cause lamps to come on (and if enabled, an alarm to sound) when the weight on the scale meets or exceeds values stored in memory. The memory holds the last values for a high and a low limit when the power is turned off. The user can set either one limit or both as described below.

See Section 7.1 for the procedure to set the limits. The limits can be set when the scale is in weighing or parts counting modes. After limits have been set the Checkweighing function is enabled.

When a weight is placed on the scale the LED’s above the display will show if the weight is above or below the limits and the beeper will sound as described below, if the beeper is enabled (see section 7.1).

The relay outputs are open collector drivers to control an external relay. The relays will be active when the corresponding LED is on during check-weighing. The ZERO relay output will be on when the scale is showing the display is at Zero.
