At 19:14 PST there was a critical alarm on H0:FMC-EX_CY_H2O_SUP_DEGF. By the time I got to it it was no longer in alarm. The EX chiller medm seemed to look normal to me, but trending the previously mentioned channel did show an odd flat spot in the supply temperature for the past ~3 hours (See attachments below). The tempurature began to increase again at 19:07 and seems to have gone back into its normal rythme.
