 +Both coaters now have their own ~3ph outlet (on the same 16A circuit). Installed secondary 4mm² PE connection for the sputter coater. 
 +Checked R<sub>LOW</sub> and R<sub>ISO</sub> for both coaters. 
 + 
 +==== Day 2026-06-12 (q3k, hugo, rahix) ==== 
 +On the sputter coater, installed 3 new cooling circuit flow sensors to detect problems with the water cooling loops. 
 + 
 +{{:equipment:edwards-306:20260612-interlock-flow-sensors.jpg?400|}} 
 + 
 +New interlock cable from those sensors to the control rack made from repurposed CAT6: 
 + 
 +  * **Orange:** Turbo Interlock (Main) 
 +  * **Green:** DC Interlock 
 +  * **Brown:** RF Interlock 
 + 
 +Tested system, no water leaks and interlocks work. 
 + 
 +The argon supply is still leaking close to the gas bottle.  Will need to fix that soon. 
 + 
 +Placed the two cheap environment sensors into the controls enclosures of the two coating systems. We did not rename them yet, so the mapping is "Unusually Large Staircase" -> Sputter Coater and "Chillzone" -> Evap Coater.

 Two days of work on the sputter coater. Two days of work on the sputter coater.

 Turns out RF sputter head isn't being cooled well - that might be the cause. We should dismantle it and check for damage (esp. magnets), and also try to cool it with the water chiller attached directly. Turns out RF sputter head isn't being cooled well - that might be the cause.
