    DDR Sensor

    Hi,
    Been using the DOS along with DDR for a month or so. 2 days ago I receive an alarm stating container 2 is empty when it is not. I tried stirring around the fluid (Triton core7 #2) with no luck. I am also receiving another error whereas my ATK low water level sensor is closed even though it is below water and now my ATK will not run. Maybe a bad optical sensor in my dos container 2 and ATK or can something else be going on here....
    Thanks,
    Joe

    Make sure the connectors are plugged all the way in. It's a very common mistake for people to press them in but not click them in.

    Just tried unplugging and then reconnecting the DDR to the DOS. Even tried powering down the DOS. No luck...

    May be a bad optical then. The only way to troubleshoot at home is to check the diode bias voltage if you have a multimeter with a diode setting. The diode should read 1V between 2 and 6 and between 4 and 6

    I have been having the same issue lately. If you could post how you were able to resolve it that would be great!

    Sure. I opened a ticket with Neptune. After a couple of troubleshooting steps, I was asked to send back the DDR for service. They replaced the optical sensor and shipped back. They covered all costs. I was out the DDR for about a week.

    Same issue on both my ddr’s. Clearly a design issue. I just don’t want to pay to fix it. Pretty annoying.
