Overview
Ing makabukud a safety barrier a maki switch input relay outputs, a mag isolate at mag transmit input signals ibat kareng switch contacts o proximity switches kareng delikadung lugal papunta king safety zone a maki output relay kapamilatan ning safety barrier. Ing line fault detection agawa ya kapamilatan ning LED keng babo ning module. Ing dial switch ning module magagamit ya para i-set ing input ampo output in-phase o reverse control, ampo para i-enable o i-disable ing line fault detection alarm indication function.
Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals.

Line Fault Detection(LFD)
Malyari deng pilinan deng gagamit ing "ON" a gilid ning switch keng babo ning module para a-enable ing fault detection function ampo para ipabalu ing alarm kapamilatan ning red LED light. keng site input current>7mA, short circuit alarm (SC);
keng site input current contact input mangailangan yang fault detection function (wire breakage, short circuit), ing 22k Ω resistor dapat makakonekta ya parallel kareng adwang wakas ning switch, at ing 680 Ω resistor dapat yang makakonekta keng serye (antimo akakit ya keng wiring diagram para keng switch contact II).
