1. Introduction
AD4329A-DLC is a digital load cell weighing indicator that enables use of truck scales.
By combining the AD4329A-DLC with an A&D digital load cells (LCCD20 series), a weighing system with higher
lightning resistance performance can be built, and electronic corner adjustment can be performed easily and
precisely. Up to eight digital load cells can be connected in parallel.
AD4329-DLC's interface has standard serial output to enable connection to A&D printers and displays and RS-
232C to enable connection to PCs. In addition, comparator relay output can be provided as an option.

1.1. Safety precautions
For safe and correct usage, read the following precautions carefully before using the indicator.
Precautions on design
WARNING
●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 in the indicator.
Precautions on installation
WARNING
●Do not use the indicator in the following environments:
- Where the temperature and the humidity exceed the specifications
- Where corrosive gases or flammable gases are present
- Where the indicator gets wet with oil, chemicals or water
Please note that securing the indicator to the control panel will provide the indicator outside of the
control panel with IP65 protection.
●When installing or removing the indicator, be sure to turn off all the external power supplies used
beforehand.
Precautions on wiring
WARNING
●When wiring the indicator, be sure to turn off all the external power supplies used beforehand.
●When wiring is complete, be sure to attach the terminal block cover provided with the indicator.
●Be sure to ground the indicator.
CAUTION
●Do not clamp control wires or communication cables with power lines, and do not place them close to
power lines.
●Place the load cell cable sufficiently away from high frequency circuits such as high voltage power
lines and inverter load circuits.
