Installing and Wiring the Input and Output Jacks
* These appear in this order from left to right on the terminal.
• Use M3.0 screws for the terminal.
• The wiring should use crimp contacts as shown below.
 Wiring the trigger input
The trigger input is used to cause a BL/SR/RF Series device to begin reading.
The trigger input interval is on when 8.5 to 30 V DC is input.
The BL-U1 sensor power source can be used as the input power source.
