Hi Jonah and welcome to the forums! Admittedly I’m not familiar with this line of PLC’s, however, to me it sounds more like an internal logic problem or possibly a door hardware/feedback (possibly intermittent) problem. You will need to look at the logic to see what exactly is causing the alarm to trigger. If available in this software, what I would do is setup a trend or some kind of monitoring to see what exactly is causing this fault. Is there an actual delay timer on the fault (you did mention 2 seconds) or is it latching in right away based on the feedback from the doors closed inputs? Obviously lots of things to check and difficult to tell based on the information you’ve provided.
