We had some recent problems with the PTR which has turned itself off on various occasions. Adding a temperature detector to the PTR cooling water shows that the water temperature was above the allowed 30 degrees when the PTR turns itself off. Currently the reason for this warm water is being investigated. The PTR has also been running for 26000 hours and we will have to do a check-up of the system in the near future.
