lostsoul Posted September 22, 2021 Report Share Posted September 22, 2021 Attached is my WMI setup, the "Failsafe" is a pressure sensor in the line after the pump set to turn the WMI Relay off outside set min/max's. The problem is because the pressure sensor is obviously reading "zero" with system off it will not activate the relay. So, how can I build a delay into the failsafe activation to allow the WMI pressure to build above the min. without compromising safety eg: engine still operating under WMI conditions while there is no water/meth flow due to a leak or blockage. Sorry for the story, any help will be appreciated. https://www.dropbox.com/s/yvx0n0bok36qwvu/WMI Setup.PNG?dl=0 Quote Link to comment Share on other sites More sharing options...

Adamw Posted September 22, 2021 Report Share Posted September 22, 2021 I would do it something like below. The low pressure lockout will be ignored for the first 1 second whenever the WMI activation conditions are first met. If the pressure drops low after the system has been running it will shut off instantly. MagicMike 1 Quote Link to comment Share on other sites More sharing options...
lostsoul Posted September 22, 2021 Author Report Share Posted September 22, 2021 Thanks Adam .... If the 1 sec isn't long enough am I able to increase it with affecting shut off time if there is a problem? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 22, 2021 Report Share Posted September 22, 2021 Yes. Adjust the timer 1 <= setting in Virtual aux 1 if you want that longer. Quote Link to comment Share on other sites More sharing options...
