Maintenance and Troubleshooting
Maintenance Clean the Switch
Regular Thorough Check
The safety switch must be checked regularly. The type and frequency of thorough
checks is defined by the manufacturer and the operating entity of the machine,
see Thorough-check Concept on page 18 .
The regular thorough checks serve to investigate the effectiveness of the safety
switch and detect any ineffectiveness due to modifications or external influences
(for example, damage or manipulation).
Troubleshooting
IMPORTANT • Do not use aggressive cleaning agents (such as isopropanol or spirit).
• Do not use any substances that hinder the wetting properties of lacquers.
• We recommend anti-static cleaning agents.
IMPORTANT Conduct the thorough checks according to the instructions from the
manufacturer and the machine user.
ATTENTION: Hazard due to lack of effectiveness of the protective device.
If non-compliant, it is possible that the dangerous state of the machine may not be
stopped or not stopped in a timely manner.
• Immediately shut down the machine if the behavior of the machine cannot be
clearly identified.
• If a machine fault cannot be determined or safely rectified, immediately shut
down the machine.
• Secure the machine so that it cannot switch on unintentionally.
ATTENTION: Hazard due to unexpected starting of the machine.
When any work is taking place, use the protective device to secure the machine or
to verify that the machine is not switched on unintentionally.
