Reef Angel Forum

For anyone else looking to do this and clarify one little thing. if (now()%30<10) ReefAngel.PWM.SetChannel(0,0); else ReefAngel.PWM.SetChannel(0,100); The "runtime" is actually the first set channel command line before the else. so if the above lines are used the relay or channel is on for...

thanks for the feedback Inevo & Roberto I appreciate it a lot!

Roberto, so here is the code for my dimming module. Channel 3 is the port I am attempting to set up with a 12 second on/off 24hrs a day, and turn off during feed mode; it is a DC optioned channel not a PWM. I used your code in the apply custom code here and channel3 wont operate after upload. this i...

Searching for examples have not found much that nails this so looking for guidance. So I am using my dimming module to drive external DC relays. I have managed to get them running with a simple on and off program using the saddle code programing with wizard using a delay of 0 seconds and picking a 5...

So its official in my case, within a minute after pulling the dimming leads off the Relay Box the PH reading went from its 2.45 to the more expected 7.98. Re-calibrated the probe for kicks came in at 8.21 which is right in line with my standard PH test kits reading. After an hour the reading was sti...

So if I simply removing the dimming leads from my LED drivers to the main unit, the PH probe should operate normally then, correct? This would completely remove the only dimming circuit I am using.

Kraven,
Your experience seems to be identical to mine. Any change in your results.

Old meanwell drivers didn't do that. Somewhere along the line, they changed something that started introducing stray voltage into RA through the dimming signal wire. I will unplug my LED set up and pull the dimming lead tomorrow and see if the PH probe acts normal. Its reading is absolutely unpredi...

What do you believe meanwell drivers induce to the ra ph probe readings?

One more newbie experience. After a few days of enjoying the automation of functions I am finally getting around to the probe calibration. The PH probe is wandering for an extended period of time I see 10min 20min references on other posts I have attempted 3 calibrations and the probe on the 4th is ...

I plan on one I/O expansion module for the 4 additional external relay controls I need, but with basically 8 I/O's existing thought I would at least yell it out to see if anyone has tried yet. If i move the very active relays currently in the included relay box to the future external I/O's the noise...

Was hoping to open up the relay box and hack the I/O signal to each outlet and operate some external din mounted quiet solid state relays. Anyone tried yet?
