Construction and FunctionMANUAL CEAG AUtoMAtiC tEst systEM At-s+ 40071860177 (C) December 2016 www.ceag.de4 4 6 External DLS/3Ph-bus-module andext DLS/3Ph-bus-module inverseThis electronic monitoring module acts as a (light-)switchscan and/or for monitoring of the phases of a mainspower supply (e. g. in a subdistribution board):Luminaires of the general lighting and the safety lightingare switched in mains operation in accordance with theswitch position and the settings for the controller CU-S+.In emergency operation (e. g. after a message abouta breakdown of monitored phases of the mains powersupply) the circuits of the safety lighting will be operatedaccording to the settings of the controller CU-S+.DLS/3Ph-bus-modules are available in two perfor-mances which only differ in view of the switchingperformance (inverting of the DLS circuits)!Technical Data• Mains supply for the modules– Device: 24 V DC (19 ... max. 30 V)– Cable type: 4 x 2 x 0.8 mm IY(ST)Y, Twistet Pairscreened (minimal standard).– Current consumption: 20 mA (15 ... 25 mA)with 8 connected circuits• Bus connection– RS 485– Rated current: Un = 24 V DC– Cable type: 4 x 2 x 0,8 mm IY(ST)Y, Twistet Pairscreened (minimum standard).– Connecting terminals A, B, SE• Input circuits– up to 8 potential-free disconnected– Rated voltage Un = 230 V• Switching performance of DLS-circuits DLS/3Ph– U < 138 V = OFF– U > 195 V = ON• Switching performance of DLS circuits DLS/3Phinverse– U < 138 V = ON– U > 195 V = OFF• Switching performance of 3Ph circuits (same forDLS/3Ph module and DLS/3Ph module inverse)U < 138 V = OFFU > 195 V = ONApplicationTwo operation modes are available:• (pure) DLS-mode• (mixed) DLS/3Ph-modeWith a dispatcher (pos. 5) the operation mode can bechosen.• Assembly in the subdistribution boardof the monitored circuits due to the low laying effortfor the illumination circuits (compare «Mounting andconnection of external bus modules»)• Assembly in the control cabinet AT S+ C (AT S+ S)due to reasons for simplification of the maintenance(compare «Mounting and connection of externalmodules»).• Application-environmentProtection class / -category: IP20 / IAmbient temp.: -10 ... +40°CNOTE• Please observe the regulations for bus-technology andscreening on the following pages.• For planning and application of the modules we adviceto observe the technical documentations attached tothe modules and the catalogues ofCEAG Notlichtsys-teme GmbH!• Optically, the inverse and the non-inverse DLS/3Ph-module only differ in the printed description and theitem number!• Due to break or short-circuit of the RS485-bus line allconnected luminaires will be switched on!
