3.3. Turning the power on
As a power supply, an external 24-VDC power supply (24 VDC±10% / 700mA) or a 12-VDC AC adapter
can be used.
When connected to the following instruments, power can be supplied to both instruments by plugging the
AC adapter into either the weighing instrument or the AD-8923-BCD.
(Both instruments can have their AC adapter connected at the same time.)
Compatible models: AD-4212C/D/F, FZ, FX, GX-A, GF-A, GX-M, GF-M, GX-L, GF-L, HR-AZ, HR-A
When the external 24-VDC power supply is used
Connect an external 24-VDC power supply to the DC input terminal located on the rear of the AD-8923-BCD.
Precautions on using the external power supply
CAUTION
Use a power supply within the rated voltage range (24 VDC±10%).
Never use a power supply with a voltage exceeding the rated range.
It may cause damage or heat buildup.
The AD-8923-BCD may not function properly.
Ground the FG terminal of the switching power supply used.
To avoid electrical shock and increase the system safety.
To increase the resistance against noises.
Do not share the power line with other devices.
Strong noises introduced from other devices may cause damage to the AD-8923-BCD.
Inrush current from other devices may cause the AD-8923-BCD not to start up properly.
Circuit configuration of the AD-8923-BCD may affect other devices to prevent them from
functioning properly.
Select a switching power supply with a capacity of approximately 700mA for each AD-8923-BCD.
Note that the AD-8923-BCD may not start up with a capacity less than 700mA.
If the power supply capacity is not sufficient, the AD-8923-BCD may not function properly.
Be sure to add a noise filter on the front end of the switching power supply and ground the FG terminal.
This will increase the resistance against noises.
Be sure to ground the FG terminal of the AD-8923-BCD and weighing instruments.
This will increase the resistance against noises.
