Petit losing connection

Accutrac 360i flashes Fault and doesn’t alert me. Only 25000 washes on it. The only way I know is checking the cameras every 45 minutes to an hour. It’s then that I see all of the lights illuminated in the bay. Presoak Polish etc. they all light up when it loses connection between the HMI and plc. It shuts down the wash and I get no notification, even when the connection is present. I’m using an AT&T 5g business gateway plugged into the ups.

I toggle the machine to off then back on and all is fine. This has happened three times within the last 100 cars, which has taken several days due to the weather. Any ideas?
 
You should not need the HMI connected to the PLC to operate the machine. Is this happening during a wash or when it is idle?

What fault are you getting?
Idle but that may be happenstance. The cameras showed a one minute gap. I ordered something that will text me when the power goes out. For such a highly touted machine, it should have this ability
