    What to do if SDKELI BLPS-D3L has no red light from the emitter window?
    • R
      russellgregAug 13, 2025
      If the SDKELI Safety Equipment shows no red light from the emitter window, there are several potential causes. It could be due to an emitter fault, in which case you should change the emitter. Alternatively, the receiver might be faulty, requiring you to change the receiver. Finally, the line between the emitter and the receiver could be faulty, so you should perform maintenance on the circuit.
