Spinozaweg Spinozaweg overview picture: "SM - Overview" - Cable enters the station above the nameplate "Appeltuin". Currently L1, E and L3 are "off", it is the set with "Sigma F+E". For this type, instead of "L2" it says "E" - Picture "SM - iSV" on the left-side, you can see that "L1" is flashing red for the Sigma F+E, it means that L1 and L2 are on. See explanation file "storingsverklikkers" page (5/8) "secundaire verklikker". You can see the blinking red light also in the video "C0176". This type does not have L2, but it has "E". - For 'Storingssituatie 1" (scenario 1, that we are currently building), "L1" should flash red (indicating L1 and L2 are on) for the storingsverklikker above the nameplate "Appeltuin" and "Bergse Dorpstraat" - Perhaps we can make a closeup of the "WEGA 1.2" which also has L1, L2 and L3. To throw the student off. I did not see the other installations "AA" and "XIR". THey were also not relevant for the exercise
