Can someone explain to me is very simple terms why the CWP doesn't lock out when pretreatment equipment is back washing or regenerating at night? I have been in Fresenius awhile and I was raised up being told RO will lock out during the regeneration and backwash programs on pretreatment. I often get high conductivity alarms or inlet flow pressure alarms and when I look at the times of the alarms it seems to be at night and not on start up. The staff clear the alarms and no other issues come up all day. This has confused me for along time and I have never really gotten a solid answer that I understand.

The lock out is designed that way from Marcor as I've been told in my CWP class a long time ago by Joe and other MarCor techs.
When lock out is engaged/initiated you cannot manually start the RO immediately after. That is the correct way the lock out works. During regen, RO wakes up and flushes you'll get those alarms.
The way you can test to make sure you're lock out works properly, is to manually start a regen (of course after hours/patients are off) and try to start the CWP. You'll get a Lock out alert on the screen preventing you from starting the RO.
I wouldn't read too much into those alarms any further but verify your lock out works properly and you'll bury it all behind with good feels.
