The DC Decoupler is connected upstream the Rainbow Button type RB 42 2M XI. In normal operation, the emergency call button thus runs via the standard power supply. In case of a power failure the emergency call button will be fed via the emergency power supply.
For the permanent display of elevator data , the DC Decoupler can be connected. Thus, the normal operation of the TFT display runs via the standard power supply. In case of a power failure it will be fed via the emergency power supply.
The emergency and standard power supply remains galvanically separated when the DC Decoupler is employed.
