There's no output with a pulse signal repeater and pulse rate converter. What should I do?

  1. Check the power supply wiring.
  2. Check whether the power supply voltage meets the specifications.
  3. Check the polarity of the input wiring.
  4. Check the pulse specifications of the other instruments.
  5. For voltage pulse, open collector, and non-voltage contact, check whether there is an external resistance connected to the input terminals.
  6. For current pulse, check whether the accessory resistor is connected to the input terminals. (some models may have built-in resistance, so be sure to check the specifications).
  7. Check the signal from the output terminal while using a clip or other conductor to open and short the (+) and (-) input terminals.
  8. You must apply external power to the output terminals (open collector / non-voltage contact AC switch). Check whether there is power.
