"Switched" and" unswitched" 24 V power supply
The unswitched 24 V power supply (1L+) is required for the device to function.
The switched 24 V (2L+) supplies the two digital outputs. Switching brings all of the actuators
connected to the digital outputs into the no-voltage state.
If you don't need the switching of 2L+ power supply, then both the switched as well as the
non-switched 24 V may come from the same supply.
