A signal controller is considered switched off if the signal program 0 (for Vissig signal controllers) or 99 (for RBC signal controllers) is selected or if an invalid signal program number is set.
1. Make sure that the Signal timing view is selected in the Views window.
2. Select the entry 0: No signal program in the selection list in the toolbar.
The signal controller is switched off. The effective control type of the node is set to two-way stop.
