I received a coldhead alert and now what?

Alert type

Cold head supply - return gas temperature.
The temperature difference between the helium supplied to the Coldhead and the helium returning from the Coldhead is outside a Philips threshold.

This alert is sent when there is a too low difference between the Coldhead supply and the return helium temperatures. This is an indication that the Coldhead is not functioning properly.

Criticality of alert: High
Required response time: within 24 hours
