Furthermore it shall be  verified, that all emergency control functions start up automatically (automatically by-pass of  waste water, handling of alarms etc.)   Signal test of all signals according to signal lists. All signals shall be tested from source to  software. For analogue signals range and scale shall be verified. For level transmitters offset and  range shall be related to fix points in the construction.   Control of isolating   Control of tightening moments   Control of all power circuits  8.24.3 Panel factory test  Power section  The Panel factory test shall as minimum covers:   Control of component sizes   Control of conductor dimensions   Control of wiring numbers  Control of conductor colours   Control of loose connections   High voltage tests   Control of phase orders   Control of measurement transformers   Operation of fuses, motor protection, disconnectors etc.   Control of fault current relays with tester
