Pump oscillation help please
 

I acquired a second DC8. I want the PH's on the right side to alternate opposite the PH's on the left side.

Right PH's on the right on for 15 minutes (Left PH's off).
Then the left side for 15 minutes (Right PH's off).


If I program my AC3 with the info below all pumps are on/off for 15 minutes, then they all go off and stay off:

OSC 015/015 ON/OFF Then PM1 ON
OSC 015/015 ON/OFF Then PM2 ON
OSC 015/015 ON/OFF Then PM3 ON
OSC 015/015 ON/OFF Then PM4 ON

If I program my AC3 with this data my left side only comes on and stays on.

OSC 015/015 ON/OFF Then PM1 ON
If Timer PM1 = On Then PM3 OFF
If Timer PM1= Off Then PM3 On
OSC 015/015 ON/OFF Then PM2 ON
If Timer PM2 = On Then PM4 OFF
If Timer PM2 = Off Then PM4 On
OSC 015/015 ON/OFF Then PM3 ON
If Timer PM3 = On Then PM1 OFF
If Timer PM3 = Off Then PM1 On
OSC 015/015 ON/OFF Then PM4 ON
If Timer PM4 = On Then PM2 OFF
If Timer PM4 = Off Then PM2 On

To say the least I'm a little confused

Dave-

I ran this through the simulator and it works fine. However in real time the pumps do not switch.

If Time > 13:30 Then MH1 ON
If Time > 21:30 Then MH1 OFF
If Time > 14:00 Then MH2 ON
If Time > 22:00 Then MH2 OFF
If Time > 13:15 Then T5A ON
If Time > 22:15 Then T5A OFF
If Time > 22:15 Then MLT ON
If Time > 23:59 Then MLT OFF
If Time > 21:15 Then FUG ON
If Time > 14:30 Then FUG OFF
If Temp > 78.5 Then FAN ON
If Temp < 78.0 Then FAN OFF
If Temp < 77.5 Then HT1 ON
If Temp > 78.0 Then HT1 OFF
If Temp < 77.5 Then HT2 ON
If Temp > 78.0 Then HT2 OFF
If Temp > 81.0 Then MH1 OFF
If Temp > 81.5 Then MH2 OFF
If Power 015 Then MH1 OFF
If Power 015 Then MH2 OFF
If Power 015 Then SKM OFF
If Power 015 Then WMK OFF
If Power 000 Then ALM ON
If Time > 00:00 Then ALM OFF
Max Change 030 M Then MH1 OFF
Max Change 030 M Then MH2 OFF
Max Change 030 M Then SKM OFF
Max Change 030 M Then WMK OFF
If Temp < 75.9 Then ALM ON
If Temp > 81.9 Then ALM ON
If Time > 00:00 Then RET ON
If Time > 00:00 Then SKM ON
If Time > 00:00 Then WMK ON
If Time > 00:00 Then ATO ON
If FeedA 000 Then RET OFF
If FeedA 005 Then SKM OFF
If FeedA 000 Then PM1 OFF
If FeedA 000 Then PM2 OFF
If FeedA 000 Then PM3 OFF
If FeedA 000 Then PM4 OFF
If FeedA 005 Then WMK OFF
If FeedA 000 Then ATO OFF
If FeedB 000 Then RET OFF
If FeedB 005 Then SKM OFF
If FeedB 000 Then PM1 OFF
If FeedB 000 Then PM2 OFF
If FeedB 000 Then PM3 OFF
If FeedB 000 Then PM4 OFF
If FeedB 005 Then WMK OFF
If FeedB 000 Then ATO OFF
If FeedB 005 Then SKM OFF
OSC 005/005 ON/OFF Then PM1 ON
If Timer PM1 = ON Then PM3 OFF
If Timer PM1 = OFF Then PM3 ON
OSC 005/005 ON/OFF Then PM2 ON
If Timer PM2 = ON Then PM4 OFF
If Timer PM2 = OFF Then PM4 ON
OSC 005/005 ON/OFF Then PM3 ON
If Timer PM3 = ON Then PM1 OFF
If Timer PM3 = OFF Then PM1 ON
OSC 005/005 ON/OFF Then PM4 ON
If Timer PM4 = ON Then PM2 OFF
If Timer PM4 = OFF Then PM2 ON

WOW 49 views and no help :(

Really 61 views and still no help. . .

You're overthinking it ;)

Try this:

OSC 015/015 ON/OFF Then PM1 ON
If Timer PM1 = ON Then PM2 ON
If Timer PM1 = OFF Then PM2 OFF
If Timer PM1 = ON Then PM3 OFF
If Timer PM1 = OFF Then PM3 ON
If Timer PM1 = ON Then PM4 OFF
If Timer PM1 = OFF Then PM4 ON

This is as simple as you can do it - by making 1 pump the "master" and having the state of each of the other pumps spend directly on the state of the master. PM2 will do exactly what PM1 is doing. PM3 & 4 will do exactly the opposite of PM1.

THAT WORKED! Thanks RussM.

My apoligize to the forum for being such an a$$. Fustration was setting in and I knew you folks had the answers!
