ATK Optical Sensor Operation

Mcdy · Aug 21, 2019

Good evening,

Just finished up installing the final ATK RO_LO sensor into my Synergy Reef ATO. Really cool setup but a couple of questions on the FMM.

With the settings on AUTO for the FMM it shows to be "off" and not "auto" --> normal??

The third optical sensor is showing open instead of closed when it is sitting in 9 gallons of water --> It should be closed when full of water correct? Any suggestions to fix?

If someone can verify this code so I do not burn up the pmup that would be great!!!

Fallback OFF
Set OFF
If ATK_LO OPEN Then ON
If ATK_HI CLOSED Then OFF
If RO_LO OPEN Then OFF
If Output Maintenance = ON Then OFF
When On > 003:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 030:00 Then OFF

Also, I just became a R2R supporter and wasn't sure when that will display on my account?

Top of the morning to you!!
Welcome to R2R and the wonderful world of Apex Control...

Your atk being on (Auto)off if your atk low sensor is closed (wet) is correct. If it opens and is dry the programming will commence and fill until closed again along with your other conditions.

Secondly,
Your RO sensor that you installed. Start by going into your fmm module and making sure the port you plugged into (#3?) is set to Optical sensor and uncheck “Auto”.

Also make sure it’s plugged in all the way

Alright so the FMM in "auto" remains in an off status until it is triggered by a sensor to come on?

This morning I woke up and all is reading correctly. ATK HI sensor is open and the atk lo and ro lo sensors are closed. Which is what I would expect from a dry (open) and wet (closed) sensor.

If I push any harder on the sensor wires I am going to push the board through the plasticky housing,...LOL.

You guys rock as always,.....that's why I became a supporter!!
