With a newly developed digital load cell and an ultra-high speed processing

Best-in-classprecision

module, high level precision of 0.08g (3σ)*1 has been realized.
With this high accuracy checkweigher, you can minimize the giveaway ofmaterials above the specified weight and contribute to reductions in
production costs.

UniqueUniquemodularmodulardesigndesignThe AD-4961 consists of four units: infeed conveyor unit, weighing conveyor unit, control unit
and base unit, allowing fast and simple assembly.
In the case of system shutdown, no need to wait for a service engineer to respond to the issue-simply
replace the unresponsive module to shorten system downtime and maximize production efficiency.

Optimization
Optimizationofof weighing
weighing
configuration
configuration

By inputting throughput (products per minute) or belt speed (m/min),optimal weighing conditions can be automatically set, allowing for
precision weighing without inputting various settings.

New functions
1. Feedback control
This function outputs the difference from the target value in filling and packing machines when
there is a difference between the target and actual values (pulse width output method using
DO output and zone output method using multiple DO outputs).

2. Weighing Mode
Addtion of Optimal Mode
Optimal mode extends the sampling time to ensure accuracy.
This mode is effective for measurement of small, light products and long (dimension) products.
Note: The judgment timer is extended leading to a throughput that is lower than standard judgment processing.
Additionally, rejection processing may not be received in time due to delayed judgment output
of rejectors connected at subsequent stages.

3. Target weight tracking
The target weight tracking function calculates a moving average for weighing values and sets a new target
value based on the target, high limit and lower limit values and the settings for the target weight tracking.
This function allows the checkweigher to perform checkweighing while tracking changes inweight of the products. Select “Enable” to use the target weight tracking function.

4. Reject confirmation
Reject confirmation is a function for monitoring products using a photosensor that is attached tothe ending side of the flow, such as the passing or discharging side of a rejector.
Allows users to check for errors in which products other than those specified pass as OK.

5. DO (Digital Output) additional features
Consecutive Fail, Error Output, Total Number Count, Conforming Item Count
Bin Full, Reject Confirmation

6. DI (Digital Input) additional features
Air Pressure Error, Bin Full, Emergency Stop, Reject Confirmation

7. Dump Printing
Print raw data summary results or statistical data on an RS-232C connected printer capable ofdump printing (such as the AD-8126).
Print the raw summary data or weighing data from processing small numbers (approximately
100pcs/min or less).
Data can be sent to a serial connected computer if desired.

8. Serial connection
Weighing results transmitted by RS-232C after each measurement.

Historyfunction

Operational history
The history of configuration changes can be recorded and displayed.
Suitable for use in HACCP programs along with the weighing history function.
Users can be registered and their scope of permitted operations
controlled according to 4 management levels.

[ Operator ][ Supervisor ][ Quality Manager ][ Administrator ]By assigning each user to the appropriate level of access,inadvertent operations can be avoided.*2*2"Operator" is set when the power is turned on.

Weighing history
Weighing results are automatically recorded in a USB flash drive during weighing.
Output data: date, time, group product number, weight data and judgments.

Weighing history output example:

Only USB memory formatted in FAT32 can be used.
The weighing history that is outputed to the USB memory
is saved in the memory root in CSV format.
