GHL Programmable Logic Check

Building on the GHL example of a delay on after maintenance mode trying to get this to work for 2 maintenance modes and 2 feed/filter modes. The delay times are not what will be actually used just easy times for me to tell apart when testing on empty outlet with a light plugged in.

The GHL example used Delayed off then inverted it at the next gate. How is that different from using Delayed On and not inverting it?

Does this logic look correct?

Attachment 13011

Got it to work had to switch the feed/filter to delayed on and remove the invert function.

I do not understand why though.

Attachment 13012

Think I figured out why
Filter not activated = 1
Maintenance not activated = 0
I did not see that in the manual

Edited to add

I should have read the manual closer
