2-2 Wiring „ Functions and Connections of the Control Circuit Terminals 2 Design *1. Simultaneous input of current and voltage is not possible. Do not connect the signal lines simultaneously. *2. By factory default, multi-function output P1 is set to NO contact. To switch to NC contact, change the C031 setting. 2-23 Terminal function Terminal symbol Terminal name Function and connecting method Wire size Contact input (for switching function) S1 S2 S3 S4 S5 Multi-function input Select functions and allocate them to terminals S1 to S5. (The figure below illustrates the wiring of the sink logic.) SC S5 S4 S3 S2 S1 Shield wire of 0.14 to 0.75 mm2 Recomme nded wire size:
