    Laser Trumpf L3030 - showing fault: "Error - Cooling Unit 1"

    Please help, give me an advise with this fault. Because of this error the laser is not working at all. Everything seems ok with the cooling water. Could you first give me a clue what actually "Cooling Unit 1" is and is there a "Cooling Unit 2" ? Where should I look for the problem? Any advise...
