(2-4) Load cell connection
Please use 6-core shielded cable to connect the load cell.
If uses 4-core cable, please short “EX+” and “S+”、“EX-” and “S-”. If the cable is longer
than 3m, it’s strongly advised to add a magnetic loop (optional component) on the
RS232 interface of the indicator to enhance the anti-interference ability.
2.3.3 RS232 connection
Please use 2-core shielded cable. If the transmission distance is longer than 3 meter, it‟s strongly
advised to add a magnetic loop (optional component) on the RS232 interface of the indicator to ensure the
reliability of the data transmission.
（2-5） RS232 connection
▲. Indicator must be reliably connected to load cell, and the shielded-cable of load cell
must be reliably connected to underground
▲. To protect the indicator and load cell, we cannot plug or withdraw the connector when
the indicator is power on.
▲. Both the load cell and indicator are static sensitive devices. You must adopt
anti-static measures. The electric welding operation and other strong electric operation
on the scale platform are strictly prohibited. In order to protect the operator, indicator, and
relevant devices, you should install lightning rod in the thunderstorm frequently happen
