General troubleshooting Always try to get a detailed description of the complaint! This troubleshooting guide is to remind the service technician, to check the simple things first, a visual inspection can often help with fault finding. If visual damage can be seen, replace all broken parts. If everything looks normal, or broken parts are changed, it is recommended, that a low voltage test is carried out. Disconnect the machine from the input supply and remove covers, then check: • Are there any breaks in the cables? • Are the cables correctly connected? • Are there any loose components? • Are mains fuses/circuit breakers OK & correct valves? • Any signs of burning or arching? Connect the machine to the mains input supply and check: • Is there a stable three phase 400VAC input inside the machine? • Is the machine in shut down mode? • Are the settings OK?
