Jenne told me this afternoon that the laser had tripped.  The crystal chiller indicated an error with
flow sensor 1.  All the flow sensors in the chiller are the vortex style and have no moving parts
and are not likely to fail in the same manner as the old turbine ones.  My guess is that after ~31k
hours of service, it's time to start scheduling a time where we switch the chiller out for the spare
and send this unit back to Termotek for servicing - who recommend that the servicing be done annually.

    This is the second time in about 4 days that the laser has tripped because of this problem.
