first osc program - brs doser

[jandree22]

Want to get my brs doser setup on an osc program. Measured actual output at 1.8 mL\min and want to dose 12 mL over two doses (6 mL ea). Figured this to 3:20 for each dose. I also prefer it to run at 8am and 8pm. Will this accomplish it?

Fallback OFF
Set OFF
OSC 480:00/003:20/236:40 Then ON

Also, will this only start after midnight following the initial send command, or the first time it hits either 08:00 or 20:00 hrs?

thanks

Here you go.

Set OFF
OSC 000:00/003:20/000:40
If Time 08:04 to 19:59 Then OFF
If Time 20:04 to 07:59 Then OFF

-- The Output will be ON for 3m20s at 8am and 8pm. Otherwise it is always off.

Ah I see how you got there. Cleaner, thanks again.

How would I change this to dose 12 ML over a 12 hour span, each hour dosing 1 mL for 12 doses(amusing my BRS pump is 1ml/min) between 8am and 8pm?

I believe it would be:

Set OFF
OSC 000:00/001:00/059:00
If Time 20:00 to 08:00 Then OFF

[Heavymman]

Thanks, wouldn’t I still need this too?

If Time 08:04 to 19:59 Then OFF

[CoralFan1776]

I didn't think so but maybe I misunderstood.
With the If Time 08:04 to 19:59 Then OFF it would only be allowed to run once per day from 08:01 to 08:04.
I was under the impression you wanted it to run once per hour for one minute for 12 hours per day.

The OSC command will cause it to be on for one minute and then off for 59 giving you the once per hour part.
That's why I added the If Time 20:00 to 08:00 Then OFF line so it wouldn't run from 8pm to 8am.

[Heavymman]

OK, that makes sense. Thank you for the clarification.

[Heavymman]

Ok, the program is running the reverse. It’s off for the first minute of the hour but on for the next 59mins. Not sure what to change.

[CoralFan1776]

Two things.
The Set OFF isn't needed. Habit...

The full OSC statement should be OSC 000:00/001:00/059:00 Then ON.
It sounds like you have OSC 000:00/001:00/059:00 Then OFF.
You can do it either way. You are just specifying which parameter is on versus off.
You can either change your Then OFF to Then ON or you can change the second time parameter to 059 and the last to 001. IE: OSC 000:00/059:00/001:00 Then OFF.

Got ya, thank you
