keyword=Right arm Q2 trip (helium level low?)The right arm Q2 tripped, "INTERLOCK FAULT" and helium level low (~55%). Below are the power supply screen. Paged tech on call, was told that this is a known problem but it will take days to find the reason, A temporary solution is to wait for the helium level to come back (yes it is coming back slowly), then reset the power supply.
