- Check that the electric lock - if any - is properly fastened and that the mechanical release device operates properly.
- Check connections and electric cables
- Check leaf stability and make sure that they move smoothly and frictionless along the whole stroke.
- Check that motion speeds, involved forces and installed safety devices are working appropriately.
- Clean sensors and check that presence detectors activate properly.
Once maintenance is completed reset the partial cycle counter and the event memory (see paragraph "MAINTENANCE").

32) MAINTENANCE PROGRAM
To ensure that the automatic door keeps running safely along time, we recommend to carry out the maintenance operations once every
6 months.
The installer can set the number of opening/closing cycles after which the "SCHEDULED MAINTENANCE" message will appear on the
display of the ET-DSEL digital programmer (P48 parameter).
Warning!
Before performing any operation on the automated equipment cut off the mains power supply.
Warning!
any potentially damaged or worn component must be replaced.
