Emission
Electromagnetic compatibility
Note!
The user must ensure compliance with EMC Directive 2004/108/EC using
appropriate controls and switching devices.
If an INTORQ rectifier is used for the DC switching of the spring-applied brake and if the
operating frequency exceeds five switching operations per minute, the use of a mains filter
is required.
If the spring-applied brake uses a rectifier of another manufacturer for the switching, it
may become necessary to connect a spark suppressor in parallel with the AC voltage.
Spark suppressors are available on request, depending on the coil voltage.
Heat
Since the brake converts kinetic energy as well as mechanical and electrical energy into heat,
the surface temperature varies considerably, depending on the operating conditions and
possible heat dissipation. Under unfavourable conditions, the surface temperature can reach
130
_
C.
Noise
The switching noise during engagement and disengagement varies depending on the air gap
”s
L
” and the brake size.
Depending on the natural oscillation after installation, operating conditions and state of the
friction faces, the brake may squeak during braking.
Others
The abrasion of the friction parts produces dust.
