That's how I turned it on according to the instructions.
Unfortunately, this connection does not work, i.e. it seems to me as if there is no power supply because no power diode is lit in any photocell. How I connected it: Drive: GND terminal - COM terminal (receiver) Drive: PE terminal - NC terminal (receiver) Plus (plus) photocell (transmitter) Photocell (transmitter) minus-minus (receiver)
Question from where does Fotokom (receiver) power supply come from? Thanks in advance for your help
You get power from GND and 24. That's why 24 is in the drive. Your photocells can be powered by both alternating and constant voltage. Of course, the power supply may be different than the one from the drive but it is easier and more convenient. Before assembling the photocells, they had to be checked "on the table" to see if they were functional at all. I have a habit of checking the operation of these types of devices first to know if and how they work.
They look at the diagram above, I wonder if I should release two cables from the GND (drive) output, one of which will go to the receiver and the other to the NC? Can I bridge them, i.e. connect GND to the minus wire between the receiver and the transmitter. It would appear that GND, NC and minus the transmitter, minus the receiver are on the same wire?
At first glance, it seems that these masses unnecessarily combine. However, the analysis of the connection diagrams confirms that three cables are practically connected to the ground terminal. One from the supply of photocells, the other from the NC contact and the third to the local button. Thus, one of them can be eliminated and combined, as per the couch.
