2 Installation and Wiring
2.1 Connection of Power Supply
M02 weighing indicator connects DC24V power supply as follows:
Power supply connection
2.2 Connection of Load Cell
M02 weighing indicator connects bridge type resistance strain gauge load
cells by 6 wires or 4 wires as follows. When you use 4-wired load cells, you must
bridge the SN+ with EX+ and bridge the SN- with EX-.
The signal definition of each port of the load cell connector is as follows:
EX+: Excitation+ EX-: Excitation- SN+:Sense+ SN-: Sense- SIG+: Signal+ SIG-: Signal-
