The following table lists the inspection and maintenance intervals:
Device/part of
device
Time interval
What to do?
Brake BE03
•
If used as a working brake:
At least every 3000 operating
hours
1)
•
If used as a holding brake:
Every 0.5 to 4 years, depending on
the operating conditions
1)
Inspect the brake
•
Measure the working air gap
•
Inspect the switch contacts and re-
place them, if necessary (e.g. in case
of burn-out)

1) Wear times are subject to many factors and can be quite short. The system manufacturer must calculate the required inspection/
maintenance intervals individually in accordance with the project planning documents.
2) For EDRE250 – 280, EDRN225 – 315 motors with relubrication device, note the shortened relubrication periods in chapter "Bearing
lubrication EDRE250 – 280, EDRN225 – 315 motors with relubrication device /NS".
3) The interval depends on outer influences and can be very short, e.g. in the event of high dust concentration in the environment.
