7.1 Safety notes
Initial commissioning
For initial commissioning, the following principles apply:
• Take protective measures against dangerous contact voltages in accordance
with pertinent regulations.
• The component must be fully assembled and properly adjusted. All screw
connections must be securely tightened. All electrical cables must be installed
correctly.
• Reliably secure machine parts which have already been connected against
inadvertently being switched on.
• Relubricate all lubricating points.
• Make sure lubricants are used properly.
•
After a modification to the component, a reassessment of residual risks is
required.
Commissioning
For commissioning, the following principles apply:
• Only qualified personnel may commission the component.
•
Make sure that all connections are functioning properly.
• The safety devices on the component must be completely installed, in working
order and function properly. Check the function before starting any work.
•
When switching on the component, the danger zones must be clear.
• Remove any liquids that have escaped without leaving residues.
7.2 Notes on commissioning
Before starting commissioning observe the following:
• Make sure that there are no foreign materials in the system.
• Actuate all positions of the valve once by applying compressed air.
• When TEFASEP is used as a sealing material, the valve must be sterilised
before the first product run and briefly brought to the closed position
immediately after sterilisation to ensure optimum tightness and the lift stroke
of the valve disk on the main valve checked. For detailed information see
Section 9.2, Page 40 and Section 10.6.6, Page 73.
•
Clean and sterilise the pipe system prior to the first product run.
• During commissioning, regularly check all sealing points for leaks. Replace
defective seals.
