(2) System configuration procedures : Multiple module connection system
1. Set the rotary switches.
Setting the switches on the main module
Make sure the address of the MAIN circuit on the main module is set to "1" (labeled A in the figure below) and that
the address of the SUB circuit on the main module is set to "51" (labeled B in the figure below).
The address of each SUB circuit should equal the sum of the MAIN circuit address on the same module and 50.

• Analog Input
• IT terminal
System configuration diagram (one pump system)
Within 50 seconds after the power is switched on, the following codes will appear on the LED:
• [****] will appear on LED1 in the MAIN circuit board (labeled A in the figure above).
• [0000]→[****] will appear on LED1 in the SUB circuit board (labeled B in the figure above).
Then, the setting item "SW3-3" (page 81) will appear on the LED.
