xEM Access Controller v2 Problems

I’ve been having problems with my new xEM Access Controller v2 I just received, programming the chips was fine adding/removing Tags is also fine, But if it’s powered for more than a couple minute it glitches and the really rapidly opens and closes and it’s set to 5 seconds

Sounds defective… we do functional testimg but don’t do burn-in for any length of time… hit the orange floaty help button on the DT website and send your order number. We’ll sort you out.
