WARNING | |
Risk of injury through electric shock and damage to the device! Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals. |

Power contacts
The voltage Up of the power contacts (+24 VDC) supplies the following consumers:
- Incremental encoder (terminal points 3 and 7)
- Digital inputs (terminal points 4 and 8)
- Output stage driver of the pulse width current terminal
Order of switch-on of the supply voltages The voltage Up must already be present at the power contacts when the K-bus voltage is switched on so that the internal circuits (output stage drivers) can be initialized. |
WARNING | |
Valves are not reset if the K-bus voltage fails! If the K-bus voltage fails (5 V, supplied from the supply voltage Us of the Bus Coupler), the output drivers are not reset! This means that the valves are then not driven back to the initial position! |
