2. Setting the indicator
By changing the factory settings for the indicator, it can be changed to have the appropriate settings for your scale.
The parameters set are maintained in the memory even after shutting down the power of the indicator until the
indicator is initialized or those settings are changed. The following settings require quality manager or higher
permissions. (Refer to “5.5 Managing User Level for Logging In” of the instruction manual for setting the management
level.)
2.1. Weighing unit, decimal point position and division
１. Touch the Setting key on the weighing screen to display the setting screen.
２. Touch the Weighing button on “Balance” tab and set the weighing unit, decimal point position and division for
weighing products into the each field on “Weighing Setting 1” tab.

2.2. Weighing capacity
1. Touch the Setting key on the weighing screen to display the setting screen.
2. Touch the Weighing button on the “Balance” tab and enter an appropriate capacity (rated capacity) for your load cell
into the field “Capacity” on the “Weighing Setting 1” tab. (Example below is when the 1000 g is entered as capacity.)

4. The “Weight value enter” screen is displayed after finishing zero point calibration. Enter a mass for the weight to
be used for calibration. (The weight value can be set between 0 g and capacity (g) of the load cell.)
Fig. 16 Weight value enter screen
5. The “Span calibration” screen is displayed after you have finished entering the weight value. Place a weight of
the mass entered on the load cell. Wait until the numerical value is stabilized, and then perform the span
calibration.

AD4412-CW 13
2.4. Conveyer length
By changing the factory settings for the indicator connected to the weight checker, settings can be changed to those
appropriate for your weight checker. The parameters set are maintained in the memory even after shutting down the
power of the indicator until the indicator is initialized or those settings are changed. The following settings require
quality manager or higher permissions.
1. Touch the Setting key on the weighing screen to display the setting screen.
2. Touch the Main Unit button on the “System 1” tab to display the main unit setting screen.

3. Set the length for your conveyer in the field “Conveyer Length” on the“Main Unit 1” tab. (The indicator must be
restarted to enable those settings.)

2.5. Photo eye sensor
Setting the photo eye sensor
1. After connecting the photo eye sensor to the I/F terminal, touch the Setting key on weighing screen to display the
setting screen. Touch the Main Unit button on “System 1” tab to display main unit setting screen.
2. Set the “Curb Chattering”, ”Photo Eye Sensor Polarity” and ”Photo Eye Sensor Timeout” on the “Main Unit 2” tab.

3. Settings for products
When using the indicator as weight checker, it requires settings according to the type of products to be conveyed in
order to detect and reject properly.
The parameters set are maintained in the memory even after shutting down the power of the indicator until the
indicator is initialized or those settings are changed. The following settings require quality manager or higher
permissions.
3.1. Speed
1. Touch the Product key on weighing screen to display the product screen.
2. Touch the Edit key on the product screen to display the product edit screen.

Fig. 24 Product edit screen
AD4412-CW 17
3. Touch the Detect Parameter button on the “Detect Function” tab to display the weighing parameter setting screen.
Fig. 25 Detect parameter setting screen
4. Enter an appropriate speed for your belt conveyor in the field “Speed” on the “Weighing Parameter Setting 1” tab. (The
speed for the belt conveyor must be calibrated beforehand.)
Fig. 26 Selecting the speed
18 AD4412-CW
3.2. Product length
1. Display the product edit screen in the same way as “3.1. Speed” described previously, and then touch the Detect
Parameter button on the “Detect Function” tab to display the weighing parameter setting screen.
2. Set an appropriate length for products to be conveyed in the field “Product Length” on the “Weighing Parameter
Setting 1” tab.
The product length is used for continuous unsplit detection. (Setting it to a value longer or shorter than the products to
be conveyed may cause a detecton error.)

Fig. 28 Setting the product length
AD4412-CW 19
3.3. Detect basis
1. Display the product edit screen in the same way as “3.1. Speed” described previously, and then touch the Detect
Basis button on “Detect Function” tab to display the detect basis setting screen.
2. By setting “Target”, “Hi Limit” and “Lo Limit” on the “Detect Basis Setting 1” tab, the indicator detects weighing values
that exceed the upper limit (Hi Limit) as being overweight and weighing values below the lower limit as being
underweight.
(When setting the reject stage to stage 5, the upper-upper limit (Hi Hi Limit) value detects very overweight and lower-
lower limit (Lo Lo Limit) detects very underweight by adding upper-upper limit and lower-lower limit to those settings.)
Those detections can also be used as output conditions of the DO/DI. Refer to “3.4 Setting the DI/DO” for details of
the setting method.
3. Refer to “5.7. Summary of Weighing Result” in the instruction manual for details of summary of weighing results using
the detect basis described above.

Fig. 30 Detect basis settings
20 AD4412-CW
3.4. Setting the DO/DI
Setting the DO is described using the connection example shown in “1.2. Connecting the external equipment”.
The example below is when an output to the conveyer is set to DO1 and an output to the tower light is set to DO2.
(DO number is a number set by yourself at connection.)

3. Touch the DO Map button to display the DO map screen.

4. The example is when “○” is placed in the field “Belt Running” for “DO1” to operate the belt conveyer while weighing.
“○”is placed in the field “HiHi” and “LoLo” for “DO2” to reject products using the rejecter at upper-upper (HiHi) detection
or lower-lower (LoLo) detection.

5. Return to the DO setting screen and touch the AD-4412-CW button to display the DO operation setting screen.
Fig. 36 DO setting screen
6. In this example, DO does not need to be set for the belt conveyor and tower light. However, when using a flipper, etc,
set the delay time as “the time until the weighing product reaches the rejecter after detecting it at the end of the
conveyer” plus "the swing time for the flipper of the rejecter”.
(However, the swing time for the flipper of the rejecter varies depending on settings for the cushion needle of the air
cylinder. So, fine adjustment is required for it.)
Fig. 37 DO2 operation setting screen
7. Hold time is the time to output the signal. There is a possibility that a jitter of about 50msec is generated at the hold
time. So, it must be set with sufficient leeway.
If DI connection is made for other external equipment, see "9.13. DI (Digital Input)" in the instruction manual.

3.5. For additional usage
This application note shows descriptions from connecting the indicator to basic setting. Since those descriptions are only
for basic connection methods and functions, the indicator can also be
described in this document, such as providing feedback to the packing machine or charging machine (“9.10. Feedback
Control (FC)” in the instruction manual). Refer to the instruction manual for details of descriptions.
