Ozone code

[Aywin]

Does anybody know what the command line would be to turn off my ozone generator after a set time IF the ozone was not increasing. The idea is that if the ozone was not going up to a preset level i can turn off the ozone in case the air pump had died. Without air it destroys the generator and i am trying to protect it.

Depending on the time your ozone outlet run to maintain your ORP level you can set a VO as a timer outlet to prevent your generator from running too long due to lack of air flow:

Ozone_Flo ( timer )

Set OFF
If Outlet Ozone = ON then ON
Defer xxx:xx Then ON

Ozone

Fallback OFF
If ORP > XXX Then OFF
If ORP < XXX Then ON
If Outlet Ozone_Flo = ON Then OFF

So to be clear I can do a VO so that if after a pre-determined time say, 10 minutes if the ozone doesn't increase it will turn off the Ozone Generator to protect the Generator from damage due to lack of air.These are my current settings for the generator
Fallback OFF
If ORP > 340 Then OFF
If ORP < 294 Then ON

Yes, you have to determine how long your O3 generator run during normal operation and from there you can set the outlet . You can also add a Min Time statement to this outlet to prevent in any case to generator to turn back ON before you take action .

Is there a command that i can use to protect my tank if I accidentally turn my ozone settings to ON instead of Auto, so that it will turn off at an orp reading of 340?

If you manually turn the ozone generator outlet to ON either by mistake or otherwise there is not much you can do except setting an alarm to remind you to turn it OFF , unless your ozone air pump is also run from the controller : in this case you can set also a timer VO to shut it OFF . Or you can also set a statement to turn the air pump OFF if the ORP level get too high . But in any case the ozone generator outlet will stay ON and fry the generator eventually . Be aware .

Use an If ORP > xxx Then ON statement in your email alarm outlet.
