Machinery Tester
Useful Information regarding EN60204 Test Instruments for Safety Testing of Electrical Equipment of Machines in compliance with IEC60204 / EN60204
Prior to machine commissioning, the safety of the electrical and electronic equipment must be tested and documented by carrying out appropriate tests. All tests required are described in IEC60204 /EN60204.
Once the electrical equipment is connected to the machine, the following tests must be carried out:
• The continuity of the protective bonding circuit,
• Insulation resistance,
• Voltage test,
• Protection against residual voltages.
Electrical equipment of machines starts at mains connection point and ends at the furthest machine part. The following are considered as machines in compliance with IEC60204/ EN60204:
• Metal processing and working machines
• Rubber and plastic machines
• Assembly machines
• Conveyor technology
• Food machines
• Print, paper and cardboard machines
• Test and measurement instruments
• Packaging Machines
• Leather, simulated leather and shoe machines
• Washing plants
• Construction and building material machines
• Compressors
• Pumps
• Mining and rock crushing machines
• Cooling and air conditioning systems
• Heating and venting units
• Elevators
• Pig iron working machines
• Leisure Centres
• Movable machines (e.g. agricultural and forestry)
• Vehicles for human transport
• Textile machines
• Transportable machines
• Household machines
Etc.
The UNITEST Machinery Tester andMACHINEmaster are equipped with a builtin data memory and a serial interface. The optional software allows documentation of data on the personal computer.
Voltage testing is carried out by using model UNITEST 0113 High Voltage Tester,
Cat. No. 9030.
Individual Descriptions of Testing:
• The continuity of the protective bonding circuit at a test current of 10 A / 50 Hz with display of measured voltage drop Limit Values:
3.3 V at 1.0 mm2
2.6 V at 1.5 mm2
1.9 V at 2.5 mm2
1.4 V at 4.0 mm2
1.0 V at > 6 mm2
• Insulation resistance at test voltage of 500 V DC and a limit value of 1 Mз • High Voltage test at 1000 V or 1500 V AC (500 VA) for minimum 1 s.
Protection against residual voltage, 1s or 5s after switching-off, voltage must be below to a value below 60 V.
