Preventative function monitoring
Through the monitoring of different parameters, the ROBA
®
-brake-checker recognises safety critical operating conditions of the
brake in advance, as well as acute faults (e.g. line breakage). These are determined as they occur and are notified to the user
as a warning before the brake can no longer be operated.
Only the mechanical switching function is checked. Conclusions on the braking torque are not possible (e.g. reduced friction
value due to oiling of the brake lining)
Possible causes for the warning:
• Increasing wear
• Rising coil temperature
• Falling supply voltage
• Line voltage drop on feed lines to the brake
