Detailed instruction manual
This manual provides simplified precautions and operating instructions for AD-4411. For further information about the AD-4411, please refer to the “AD-4411 Instruction Manual” which is available for download from the A&D website (http://www.aandd.jp).
Introduction
The AD-4411 is a weighing indicator that can convert signals from strain gauge load cells and connect them to an Ethernet-based field network. It contributes to an efficient system by connecting weighing instruments to industrial control systems in plants and factories.
- Daisy-chain connection is possible without a switching hub, thanks to two communication ports.
- 7-segment green LED display with a character height of 10mm and display resolution of ±999999.
- High-speed AD conversion of 1200 times/second and digital filter enable high speed and accuracy weighing.
- DIN96x48 panel mount type with IP65 protection on the front panel.
- PC can update the settings via USB port.
Safety precaution
Read the following precautions carefully before using the indicator for safe and correct usage.
- Provide an external safety circuit to the indicator so that the safety of the whole system can be secured even if errors occur in the external power supply or the indicator.
- Do not use the indicator in the following environment:
- where the temperature and the humidity exceed the specifications
- where corrosive gases or flammable gases exist
- where the indicator gets wet with oil, chemicals, or water
- where the indicator is exposed to direct sunlight
- Turn off all the external power supplies used in the system before installing or removing the indicator.
- Turn off all the external power supplies used in the system before wiring.
- Be sure to ground the indicator.

In the case of the 4-wire connection type, attach the accessory load cell connector and wire as shown below. Change the load cell connection type (CALF17) in the calibration function to 0: 4-wire type (default value = 1: 6-wire type).
6-wire connection Set load cell connection type (CALF17) to 1: 6 wire type (Default). When you connect the load cells in parallel, use a summing box. Attach the accessory load cell connector and wire as shown below.
Calibration
Calibrate the AD-4411 to properly convert the signal from the load cell to a load value. Please prepare a calibration weight.
- After Power-On, press the [MODE/ESC] key more than 3s.
- Press the [F1/↓] key twice.
- Press the [F2/
] key. - Press the[F1/↓] key.
- Actual load calibration
- Press the [F2/ ] key.
- Press the [F2/ ] key.
- The current load cell input signal (mV/V) will be displayed. Press the [F2/ ] key to execute Zero calibration.
- If Zero calibration is successful, “PASS” will be displayed, and zero calibration will be completed.
- Press the [F2/ ] key.
- Press the [F2/ ] key.
- Set a calibration weight value by the following key operations.
- [ZERO/←] key: Moves the flashing digit to the left.
- [TARE/↑] key: Increases the flashing digit by one.
- [F1/↓] key: Decreases the flashing digit by one.
- [F2/ ] key: Confirm the setting value.
- The current load cell input signal (mV/V) will be displayed. Place the calibration weight or apply a load on the load cell. Press the [F2/ ] to execute Span calibration.
- If span calibration is successful, “PASS” will be displayed, and span calibration will be completed.
- Press the [MODE/ESC] key four times to return to the measurement mode.
