Abstract (en)
[origin: EP0165464A2] A circuit arrangement for operating a multi-concept light signal is disclosed, which is controlled via a multi-line cable connection (K1...K4) from a signal box (ST). The individual light sources (rtH, rtN, gnH, geH, geN) are supplied from a common primary circuit via a common feed transformer (TR) mounted near to the signals. The connection and monitoring of the light sources occurs via control relays (S1, S2) located in the signal unit (SE) and arranged in the control circuits or via monitoring relays (RÜ, HFÜ, J) which are arranged in the individual light source circuits and have contacts (RÜ1...3, HFÜ1...3, J1, J2) in special monitoring circuits. The control and monitoring circuits are connected in the signal unit to one phase (R) of the common primary circuit, in the signal box to the neutral conductor or to a different phase of a three-phase network. The cable lines (K1...K4) of the connecting cable are each used according to the set signalling concept as a supply, control or monitoring line. <IMAGE>
