[RASMB] tripping!

[Stephen McLaughlin]

Dear Olwyn, 

we had a problem with our XLI recently.  One solution was to ensure the auxillary pump and anything else was turned off before firing up the XLI.  Unfortunately, it reoccured again and the engineer replaced one of the boards on the XLI.  Has been ok since. 

Best wishes, 
Stephen
