Installation and Precautions
3.1.1. Installation and Precautions
The AD-4329A weighing indicator is a precision electronic instrument. Handle the
indicator carefully.
The operating temperature is -10
Do not install the scale in direct sunlight.
Misoperation or other problems may be caused by an unstable power source including
momentary power failrue or instantaneous noise. Use a stable power source.
Do not connect the power cord before the installation is finished.
Please confirm that the local voltage and receptacle type are correct for your scale.
The
Operate/Standby
circuit are supplied with power in the standby state.
Use shielded cable for all connections. Connect the cable shields to the shield
terminal or case as an earth terminal.
Earth ground the indicator. Do not join the earth ground line with other electric
power equipment. There is an earth ground terminal at the power cord receptacle.
Do not install the scale in a place where it is apt to be charged with static electricity,
or where the relative humidity is lower than 45%RH. Plastic and isolators are apt to
be charged with static electricity.
3.1.2. The Load Cell Connections
Connect the load cell wires to the connector (receptacle), at the rear panel, using
the accessory load cell plug.
It is possible to connect a 4 wire cable that 1pin-2pin and 3pin-4pin are shorted, if
the distance between the indicator and a load cell is shorter than 5m.
The output voltage of a load cell is a very sensitive signal. Space the load cell cable
away from any noise source.
It is possible to connect eight 350Ω load cells.
The load cell drive is 5VDC
120mA.
