Metal Halide coming back on after turned off by time event?

[ciphros]

Again, this is on my 2nd AC3, running the same ballasts as I use on the current tank. 2nd one is currently controlling the new 270 gallon (three 400w MH). So, the icons and web interface show the #2 MH goes off at 8:30 pm, look at the tank, light is off. At 9:30 pm the #3 MH goes out. Last night, just a bit before the last MH went out #2 turned back on, then shut off with #3. Tonight, #3 went out, #2 turned back on, then shut out ~5-10 minutes later. The AC3 (both display and the web interface) show that #2 should still be off both nights. Any ideas?

Here's the program just in case there's something I'm overlooking with it.

MH1$-A01
MH2$-A02
MH3$-A03
AT1$-A04
FAN&-A05
COL%-B01
HET%-B02
ALM&-A09
DAY&-A10

If Time > 08:30 Then DAY ON
If Time > 22:10 Then DAY OFF
If Time > 07:30 Then AT1 ON
If Time > 22:00 Then AT1 OFF
If Time > 08:30 Then MH1 ON
If Time > 19:30 Then MH1 OFF
If Time > 09:30 Then MH2 ON
If Time > 20:30 Then MH2 OFF
If Time > 10:30 Then MH3 ON
If Time > 21:30 Then MH3 OFF
If Temp > 78.5 Then COL ON
If Temp < 78.0 Then COL OFF
If Temp > 84.0 Then COL OFF
If Temp < 77.6 Then HET ON
If Temp > 78.0 Then HET OFF
If Temp < 73.0 Then HET OFF
Max Change 015 M Then COL OFF
OSC 010/050 ON/OFF Then FAN ON
If Timer DAY = OFF Then FAN OFF
If Time > 00:00 Then ALM OFF
If Temp < 73.0 Then ALM ON
If Temp > 80.3 Then ALM ON

No one? No ideas at all?

I tried switching the lights to different addresses (A6 to A8), #2 still has issues with coming on for a few minutes every hour or so. #3 wouldn't go out at all. Could it be this AC3, after being used for only 6 days needs a firmware reflash? I've reset (NOT re-initialized) many times with no luck. The only other thing I can think of to try would be switching to Cat5 since it is a slightly longer (15' or so) run. Is it possible some interference is at play, sending signals to the DC8? Could it be something with the DC8 itself? This too is new with this AC3.

It sounds like you might be having some electrical interference; call Neptune tomorrow; there is a built-in test that they can walk you through.

Thanks, will give Curt a ring tomorrow when I get home from work.
