Introduction: Only channel / series of PS-3 of double passageway controller can be used at all GREIN safety to touch edge and belt switch, in order to increase the safe level that safety hits a limit and control system compatibility. Summarize series of Ps-3 of the safe controller that hit a limit. Only channel / series of PS-3 of double passageway controller can be used at all GREIN safety to touch edge and belt switch, in order to increase the safe level that safety hits a limit and control system compatibility. The safe controller that hit a limit is electric what hookup hits edge interior circuit according to safety is different, wiring of the safe controller that hit a limit can be divided for 2 lines type and 4 lines type. 2 lines type (when the hand moves restoration: Terminal 4-6 indirect 1NO from restoration pushbutton; when automatic restoration: Terminal 4-5 is direct short receive) . 4 lines type (when the hand moves restoration: Terminal 4-6 indirect 1NO from restoration pushbutton; when automatic restoration: Terminal 4-5 is direct short receive) . Remarks: Safety of 4 lines type touchs an edge to be able to undertake a controller is controlled following more establishing ties passing. Law of wiring of series connection of 4 lines type (when the hand moves restoration: Terminal 4-6 indirect 1NO from restoration pushbutton; When automatic restoration: Terminal 4-5 is direct short receive. Make clear: Can establish ties at most the length that safety hits a limit is 60m. Link lead is the longest 250m, 0. 35mm square. Controller function condition indicates a specification: When safety touchs an edge to be used alone, without safe function. 2 lines type touchs webbing to have 1NO contact, 4 lines type touchs webbing to have 2NO contact (red line and black line form) of contact of 1 pair of NO respectively.
