3.1 Proper and intended usage
3.1.1 Standard applications
INTORQ components are intended for use in machinery and facilities. They may only be used for pur-
poses as specified in the order and confirmed by INTORQ. The INTORQ components may only be oper-
ated under the conditions specified in these Operating Instructions. They may never be operated beyond
their specified performance limits. The technical specifications (refer to Technical specifica-
tions,Page20) must be followed to comply with the proper and intended usage. Any other usage is con-
sider improper and prohibited.
3.1.2 Applications with special safety requirements ("Safety Brake")
A safety certificate for the system must be provided in accordance with DIN EN ISO 13849 whenever the
INTORQ spring-applied brakes are being used in applications that have special safety requirements. The
BFK458-series brakes are suitable for use as operating brakes, as holding brakes, and as holding brakes
with emergency-stop functionality for safety applications. The safety characteristics of the safety brake ap-
ply to systems that are designed so that 80% of the characteristic torque of the brake is sufficient for the
safety function. The selected characteristic torque of the brake must, at a minimum, comply with the stand-
ard braking torque in order to meet the high safety requirements.
Please note the following conditions:
¾
Proper and intended usage of the brake as described in Standard applications,Page15
¾
Compliance with the installation specifications in these Operating Instructions
¾
Version of the brake with:
– A characteristic torque corresponding to the standard braking torque of that size or higher
– An expected characteristic torque that covers the safety-relevant functionality, even with a drop to
80%
– A noise-reduced rotor with toothed intermediate ring
¾
Compliance with the technical specifications listed in the Technical specifications,Page20 chapter.
– Ambient temperature during operation: -20° to +40° C
¾
The customer is responsible for ensuring that there is a secure connection between the shaft and the
hub.
Observe the following notices:
¾
The extended lower temperature range of the CCV version must not be reached when used as a
safety brake.
¾
The micro-switch option is not covered by the safety certificate.
¾
The service life specification for the long-life version remains valid. When it is being used as a safety
brake, however, the safety characteristic values for the non-long-life design must be used.
¾
The calculation for the safety application does not consider the wear of the friction lining or the load on
the brake due to emergency stops. These points must be checked separately when configuring the
brake.
