Proper and intended usage
3.1.1
Standard applications
Kendrion INTORQ components are intended for use in machinery and facilities. They may only be used
for purposes as specified in the order and confirmed by Kendrion INTORQ. The Kendrion INTORQ com-
ponents may only be operated under the conditions specified in these Operating Instructions. They may
never be operated beyond their specified performance limits. The technical specifications (refer to Techni-
cal specifications) must be followed to comply with the proper and intended usage. Any other usage is
consider improper and prohibited.
3.1.1.1
ATEX
The following is required for safely operating the Kendrion INTORQ spring-applied brakes BFK458 in haz-
ardous areas, device category 3, zone 2/22:
The Kendrion INTORQ spring-applied brakes BFK458 described may only be used in normal operations
within the following areas:
¾
Where an explosive atmosphere caused by gases, vapors, mists or swirled up dust is not expected,
¾
Or where, if these conditions nevertheless occur, then the use under these conditions may only take
place rarely and for a short period of time in the sense of the ATEX guideline 2014/34/EU.
Kendrion INTORQ spring-applied brakes must never be operated outside the performance limits corre-
sponding to ATEX brakes!
NOTICE
If the spring-applied brake shall be used as a holding/parking brake (refer to the name plate),
all braking torques listed in the BFK458 spring-applied brake catalog are permissible.
DANGER
Danger of explosion
Increased temperatures on the surfaces and in the friction gap can result when the maxi-
mum friction work and operating frequencies specified by Kendrion INTORQ are ex-
ceeded. These can lead to ignition.
¾
Operation is only permitted within the specified specifications.
The following must always be observed when installing ATEX brakes:
¾
The proper functioning and correct dimensioning of the brake must be ensured before it is put into op-
eration. The correct relation between the brake, motor, control and loads must be checked.
¾
If the switching times of the brake in conjunction with the control of the drive is not properly taken into
consideration, the rotational speed could increase when the motor is switched off. As a result, the brak-
ing procedure would be carried out at a much higher speed and higher friction work than assumed in
the preliminary design. This would result in higher temperatures, which would then pose a risk of igni-
tion.
