hi got called out to a hospital server room today with 2x floor mount mitsi connected to 2x PUY-P250YGM-A outdoors these units are completely separate with no central control just local controls, the room went high temp both units had a 1302 fault high pressure the hospital engineers reset the units at each controller the units run fine, all voltage fine (3ph). each unit is fed from a seprate db but the power originates from the same mini substation, im thinking power blip causing condenser fan to stop compressor to carry on running. you thoughts or idears would be greatly appreciated. thank you
