Operation and I/O Design
In General, looking at an old type hopper scale design, the simplest indicator only
displayed the weight value, other system devices communicated the control signal with
each I/O interface. And the key operations and monitoring the system were controlled
separately.
The indicator AD-4402 has an 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 one unit.
The indicator is designed so as to be able to select arbitrary keys and terminals to
control the system from the front panel keys and the I/O interface with the menu
function. The function of keys and terminals can be designed in the same way.
The system information of the sub-display can be selected in at the function list.

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
for the
F1
key and store it.
Step 4 Select [
13
] of
Forced batch finish
for the
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
for the terminal B1 and store it.
Step 9 Select [
14
] of
Batch finish
for the terminal B2 and store it.
Step 10 Set [

Step 12 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 final weight has been achieved, terminal B2 is turned on.
