Do not switch that lift on! – wiring is completely wrong. One of the landing push cores of the trailing cable is wired into the mains primary circuit. Depending on how live has been wired and also earth which are not visible, either someone could be put at risk or one or both of the PCBs will have been damaged if mains potential has been backfed into the secondry side of the controls.
One can not completely advise how this lift has previously been wired as there are no prior and after photos of the lift PCB and the halfway box.
