Installation conditions
The installation position can be user-defined.
Please ensure sufficient heat dissipation and air convection!
Do not install near to sources of intense heat!
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). Safety critical operating conditions are determined as they occur
and are notified to the user as a warning before the brake can no longer be operated.
Possible causes for the warning:
• Increasing wear
• Rising coil temperature
• Falling supply voltage
• Line voltage drop on feed lines to the brake
