We went to EEroom to investigate the chiller, since we noticed that the CHILLER_PIPE_TE monitor suddenly increased a lot (see Fig. 1). Inside the chiller room, there was an allarm for one of the two chillers (the THERMOTEK chiller), so we filled it in with water (water flow was low) and swapped the filter that seemed a bit dirty, but it didn't restarted after this operation. After some trials we decided to use the spare chiller instead.

However, the OMI chiller wasn't working properly as well (linked to the DMS allarms) but we couldn't identify the problem. So, we decided to switch off everything for safety reasons for the weekend (Neovan amplifier and slave laser pump currents wer set to 0).
