Operation and I/O Design

In General, looking an old type hopper scale design, the simplest indicator only displayed

weighing value, other system devices communicated the control signal with each I/O

interface. And the key operation and monitoring the system separately were controlled.

The indicator AD-4402 has the I/O interface to control the system, sub-display to

monitor system information, main display to display weighing data and keys to control

the system in a unit.

The indicator is designed so as to be able to select arbitrary keys and terminals to

control the system form front panel keys and the I/O interface with the menu function.

And the function of keys and terminals can be designed in the same way.

The system information of sub-display can select at the function list.

Design Example

Example Example

Example

Suppose that the I/O, keys and sub-display are as follows:

Supply start: F1 key, [0thf- 2] [6]

Emergency stop key: F2 key, [0thf- 3] [13]

Dribble signal (low power): terminal B1, [0utf- 1] [6]

Batch finish signal (low power): terminal B2, [0utf- 2] [14]

Not used recipe code at "

Not used recipe sequence

"[5q f- 8] [0]

Use default setting about sub-display [5ub f 1] [0]

Setup

Step 1 Enter the function list.

Step 2 Select the menu F1 key.

([Function] - [Function setting] - [General] - [Other] - [F1 key])

Step 3 Select [6] of Batch start at F1 key and store it.

Step 4 Select [13] of Forced batch finish at F2 key and store it.

Step 6 Select the menu terminal B1.

([Function] - [Function setting] - [Control I/O Function] - [Output] - [OUT (B1)])

Step 8 Select [6] of Dribble flow at terminal B1 and store it.

Step 9 Select [14] of Batch finish at terminal B2 and store it.

Step10 Set [6] of "Not used recipe code" at Recipe sequence.

([Function] - [Function setting] - [Sequence] - [Basic] - [Recipe mode])

Step11 Select [0] of the default menu in the and store it.

([Function] - [Function setting] - [General] - [Sub-display] - [Weighing display])

Step12 Press the ESC key several times to return to the weinghing mode.

Operation and Response

When the F1 key is pressed, a batch weighing is started and terminal B1 works.

When the F2 key is pressed, batch weighing is stopped.

When the target weight is got, terminal B2 is turned on.
