# Centrifuge Phantom Alarms
Went through the PLC and grabbed every alarm condition that shuts the down the system. (all level 1 alarms) and added them to a troubleshooting trend. Along with the running status and a few other bits that can cause shutdown.. This should help us capture the condition that shuts the skid down.
One other thing i noticed was that the LOW RS alarm is set to be a level 1 shutdown alarm in the PLC, but listed as a Level 2 Pause alarm on the HMI. if this alarm is causing the shutdown, we can update the HMI to match the logic in the PLC.
