Modbus Wiring
2-Wire RS-485 + connects to + and – connects to -
4-Wire RS-485 +’s and –’s are swapped TX+ > RX+, TX- > RX-, etc.

ION Master Connections
To communicate to an ION meter there are two communication port settings that need to be made. Comm port on the meter needs to be
set to Modbus Master Modbus Master Options Module must
have the comm port assigned to ModbusGate Connection

Common Wrench Errors
Wrench 1 (most common) Typically CCA63x (CT module) is absent I/O module is absent
Wrench 2 Typically caused by faulty wiring between remote module
connection. Wrench 3
MET148-2 (Temp Module) module is not available Wrench 4
MSA141 (Analog Module) is not available DSM303 (Remote Display) is not available
Wrench 5 MCS025 (Sync-Check) is not available
Wrench 10 CPU overload (Sepam 80 only) typically caused by excessively
large Logipam program

Wrench 1
Normally caused by: CT module not attached to relay I/O card is configured in the software
but is not attached to relay If you are unable to connect with
SFT2841 it could indicate a major fault with the base unit
On Sepam 80 it could indicate a faulty memory cartridge
