So I setup the atk auto top off system. Plugged it in, blue light came on, filled a bit, pump turned off seemed to be all good. Few mins later alarm went off. I unplugged and plugged it back in after checking connections, nothing looked out of place. Few minutes later alarm again!
It seems to go off every 10 mins, single beep.
From the atk website I can see what should trigger the alarm.
1. Your ATK has run for more than 5 minutes. This will be true anytime power is applied to the FMM and there are less than 5 fills completed by your ATK. In this condition the FMM will alarm a single long beep.
- it has done less than 5 fills, alarm is a single reoccurring beep. Not a long beep
2. If your ATK has had an opportunity to activate the IQ Fill safety feature. IQ-Fill will become active after the FMM has learned your aquariums normal filling behavior. This takes 5 fill-ups before becoming true. In this condition the FMM will alarm a single long beep.
- again not the same beep, hasn't done 5 fills.
3. Your top level sensor has been covered for more than 10 minutes. Your top level sensor will turn off your PMUP immediately, but will not create an alarm condition until it has been covered for more than 10 minutes. In this condition the FMM will alarm with two beeps.
- time is about right. Alarm goes off every 10 mins, but it's only one beep.
4. Your optional sensor plugged into input #4 is no longer under water. This could be an additional low level optical sensor in your ATK reservoir or in your sump. In this condition the FMM will alarm with four beeps.
- I have nothing plugged into input #4.
5.Your optional sensor plugged into input #3 is under water or wet. This could be a leak detection probe or an additional high level optical sensor placed in your sump. In this condition the FMM will alarm with three beeps.
- I have nothing plugged into #3.
I attached images of my setup. Maybe someone can see what's wrong.
