10.2 Maintenance intervals and measures
WARNING
Live parts may be accessible inside the inner sensor housing if a fault occurs.
Touching live parts may result in electric shock, which can cause serious or fatal
injury.
Do not open the inner sensor housing door. Maintenance work may only be carried
out by trained service personnel. All maintenance work requires a technical
qualification in electrical safety.
Switch off the external circuit breaker before carrying out any maintenance and
repair work and secure against reconnection.
Table 24 lists the recommended preventive maintenance measures and the interval for regular checks.
The inner sensor housing door must be opened to carry out the maintenance measure and the work
therefore must be carried out by
the service staff of G. Lufft GmbH or by the customer’s authorized and
trained personnel.
Further detailed information beyond the scope of this manual (maintenance, replacement, details
of units) can be found in the service manual. This is only available to employees of G. Lufft GmbH
or specially trained personnel who possess a written certificate of competence (valid certificate)
for the corresponding maintenance and service work.
If you have any questions or a procedure mentioned in this operating manual does not help to remedy
an existing problem, we recommend contacting the service technician on site or G. Lufft GmbH.
