I connected the photocell but I don’t see it in the controller.
What am I doing wrong?
Check whether you have a NPN or PNP photocell
Let’s look at input 1 in the gray box. You have 3 contacts: GND, SIG, 24 VDC
0 24 VDC
0 SIGNAL in the middle
If you go to Service/Peripheral, you see every input on the left.
No photocell, if you put a cable between GND and Signal and you see input 1 in the controller screen, you have a NPN input (see also manual)
0 24 VDC
|–0 SIGNAL n the middle
No photocell, if you put a cable between 24 V and Signal and you see input 1 in the controller screen, you have a PNP input (see also manual)
|–0 24 VDC
|–0 SIGNAL in the middle
Now, you have to know if you have a NPN (sinking) or PNP (sourcing) photocell. Connect the GND to the GND in the gray box, connect the power cable of the photocell to the 24 V in the gray box, connect the signal to SIGNAL. Switching the photocell, you should see the input changing status or you should measure between GND and SIGNAL 0 and 22-24 V.
