The control unit connects and manages the components of the warning system and thus serves the monitoring of the worksite as a control and operating unit. This feature is covered in the hardwired system by the SSE2 .
Control Unit SSE2
ZÖLLNER Signal Control Unit (SSE2)
In order to connect all components, the warning devices and the train detectors are connected to the SSE2. Via a display on the SSE2, status messages and clear text information are given continuously.
Included is the ability to manually actuate a signal and a key-operated switch to select the warning signals Ro1 and Ro2 as well as a push button to trigger the emergency warning Ro3.
