SENECA Z-8AI Configuration
The module must be turned off before it is configured.
- Configure the Modbus settings by using the SW1 DIP switch.
a) Set the baud.
| DIP Switch position 1 | DIP Switch position 2 | Baud |
| - | - | 9600 |
| - | On | 19200 |
| On | - | 38400 |
| On | On | 57600 |
| - | - | EEPROM |
b) Set the address
| DIP Switch position 3 | DIP Switch position 4 | DIP Switch position 5 | DIP Switch position 6 | DIP Switch position 7 | DIP Switch position 8 | Address |
| - | - | - | - | - | On | 1 |
| - | - | - | - | On | - | 2 |
| - | - | - | - | On | On | 3 |
| - | - | - | On | - | - | 4 |
| - | - | - | - | - | - | --- |
| On | On | On | On | On | On | 63 |
| - | - | - | - | - | - | EEPROM |
c) Set the status of the RS-485 terminator.
| DIP Switch position 10 | Status |
| -- | Disabled |
| On | Enabled |
- Set all SW2 DIP switches to ON to set all input ports to measure current.
Avensor only supports the SENECA Z-8AI module when it is used as an input for a 4–20 mA current.
| DIP Switch position 1-8 | Mode |
| -- | Voltage |
| On | Current |
