Connection examples
Logic No.1 Overall stop control (Manual reset mode) |
|
Note: |
Select contacts that can support the micro load of 6 mA at 24 V DC as the reset switch and contacts used for INT11 / INT12 (INT21 / INT22). |
|
|
Logic No.1 Overall stop control (Auto reset mode)
|
|
Note: |
Select contacts that can support the micro load of 6 mA at 24 V DC as the reset switch and contacts used for INT11 / INT12 (INT21 / INT22). |
|
|
Logic No.4 Partial stop control 1 (Manual reset mode)
|
|
Note: |
Select contacts that can support the micro load of 6 mA at 24 V DC as the reset switch and contacts used for INT11 / INT12 (INT21 / INT22). |
|
|
Customization example, based on logic No.4 Partial stop control 1 (Auto reset mode)
