Hi. How do I properly connect one pair of photocells to this control panel? Currently I have power under 50 and 51, while I have signal between 70 and 72. I have removed the jumper between 70 and 72, the rest of the jumpers unchanged 70-71, 70-74. I have a PHOT message after commissioning. When I set the panel language, motor type etc at autoset the relays are heard and KO message appears. Please help me to get this control panel up and running.
