IMPORTANT:
- Respect the electrical precautionary measures indicated in section 1.
- Read carefully and apply what is described in chapter 5.3
After having followed the instructions regarding the platform or the load receivers, the screened cable leading from the load
cell(s) must be connected to the instrument through the COM3 RS485 terminal board.
Below is the RS485 connection for digital load cells in the CoM3 of the indicator (with X15 integrated circuit):
TERMINAL MEANING
20. GND POWER SUPPLY -
21. +Vdc POWER SUPPLY +
22. TX+/RX+ Line 485 A(+)
23. TX-/RX- Line 485 B(-)
The voltage value of terminal 21 can be selected through J13 jumper, according to the
required load cells power supply.
The possible selections are 6V or 12V, working if the relative power supply is connected
to the indicator (respectively battery or external power supply, see J13 jumper description
in section 8.1).
Consequently, the functioning with only the battery doesn’t allow the connection of those
digital load cells that require 12V power supply.
In the case of digital load cells connected to a digital junction board, connect the COM3 RS 485 terminal board of the
indicator to the RS485 port of the junction board, by following the relative manual and the section 5.1.
In the case of ring connection of more digital junction boards or DGX, connect the COM3 RS 485 terminal board of the
indicator to the RS485 port of the first junction board/DGX, by following the relative manual and the section 5.1.
