I exchanged my optical sensor for the contactless level sensor and I have been testing it for about a week now before I trust it with for ATO purposes. I setup the censor and adjusted the potentiometer until it worked as expected. (I attached it to the glass with two thin strips of double sided tape at the top and bottom of the sensor.) When the water starts to drop I notice the light switching on and off with regular intervals. This is how I expect the sensor to work, if the light stays off for 5 seconds the configured socket on the plug-bar is activated.
However, after a couple of hours I notice that the water level dropped significantly but the light on the sensor is still on. (This glass is as clean as can be.) I now have to adjust the potentiometer again to get it “just right”, it then appears to work again but soon it just becomes stuck again.
I spent to whole day trying to get the sensor to work consistently but I just cannot get it right, any advice would be appreciated.
Kind Regards,
S
