SENECA Z-8AI Configuration

The module must be turned off before it is configured.

1. 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

 

2. 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

 

3. Configure the inputs
   a. Download the Seneca Easy Setup tool from the SENECA home page.
   b. Install the Seneca Easy Setup tool on a computer.
   c. Connect the SENECA Z-8AI module to the computer through a USB cable.
   d. Use the Seneca Easy Setup tool to configure the inputs.
