What to do if the control circuit is open in Leuze electronic Lighting Equipment?
If the control circuit is open in operating mode 1, 2, or 3 on your Leuze electronic Lighting Equipment, close the input circuit with the correct polarity and timing.
How to troubleshoot transmitter without supply voltage in Leuze electronic Lighting Equipment?
If the transmitter of your Leuze electronic Lighting Equipment lacks supply voltage, check the power supply unit and the electrical connection. If necessary, replace the power supply unit.
Why is the signal weak on my Leuze electronic MLC 530?
If your Leuze electronic Lighting Equipment has a weak signal, it might be due to contamination or poor alignment. Clean the front screens of the device and then check the alignment of the transmitter and receiver.
