Installing The Module
This section is explained for the environment to install the module and for the terminals of the
power source and load cell cable. Refer to each section of options for I/O interface.
4.1.
Conditions To Install The Module
The module is a precision electronic instrument. Handle it carefully.
The operating temperature is
-
10°C to
+
50°C.
Do not install the module in direct sunlight.
4.2.
Power Supply
Earth ground the module to prevent electrical shock or indicator malfunction.
If the module is not grounded, it may cause of an electric shock, or malfunction due to static electricity.
Before connecting the module to the power source, read the instruction manual thoroughly.
Do not connect the module to the power source before the installation is complete.
To avoid electrical shock, do not handle the power cable with a wet hand.
Earth ground the module. Do not share the ground line with other electrical power equipment.
The power requirement is 24 DCV,
+
10% to
-
15%.
Use a stable power source free from instantaneous power failure or noise.
To avoid a malfunction, do not share the power line with other devices.
The output voltage of a load cell is a very sensitive signal. Keep all electrical noise sources
away from the load cell and load cell cable.
Use shielded I/O cables. Connect the cable shield to the F.G. terminal or the module housing.
Ground terminal is connected internally with all connector shields.
