Should any queries arise with respect to torques, torque variations, installation position, wear, wear reserve, switching work, break-in conditions, release range, ambient conditions and the like, please contact Kendrion (Villingen) and ask for clarification before starting to use the brake. Spring-applied single-disc brakes are not ready-to-use devices, but are intended to be incorporated into or assembled with other equipment. -

Page 5: Product Description
2. Product description 2.1 Operating principle The spring-applied single-disc brake is designed to operate dry. The force generated by an electromagnetic field is utilised to overcome the braking effect produced by the spring force. The spring-applied single-disc brake engages in unpowered condition and releases when DC voltage is applied. Brakes equipped with a built- in rectifier (half-wave or bridge rectifier) can be connected directly to an AC power source. - Page 6 Reference sign list to Fig. 6/1: Solenoid housing Fixing surface Field coil Microswitch Armature 19.1 Cable gland Compression spring 19.2 Microswitch cap Stud 19.3 Locknut Friction disc 19.4 Hexagon head cap screw Intermediate ring 19.5 Machine screw Adjusting ring Protective cover Set screw 20.1 Machine screws for protective cover...

Page 8: Installation
3. Installation 3.1 Mechanical installation The hub (17) must be slipped onto a shaft provided with a feather key to DIN 6885, Hub position sheet 1. The hub must be axially secured (by means of a shaft collar, circlip or the like). Make sure that the front face of the hub (17) is at the same height as the front face of the flange (11). -

The cams (21.2) with with threaded bush threaded bush must be screwed into the bores provided in the screw plugs (23) making sure that they are in the right position (see figure). -

(25.2). The built-in rectifier (25.2) can be wired in such a way that AC side switching (normal coupling time t or DC side switching (short coupling time t ) is possible (see Fig. 10/1). Various Kendrion rectifiers are available (see Table 8/1, list not exhaustive) for direct brake connection to an AC power source via the built-in connecting terminal (25.2). -
Page 11: Dc Power Supply
The maximum permitted overvoltage during disconnection is 1500 V. If Kendrion rectifiers are used (see Table 10/1), the protective circuit required for the built-in electronic components and field coil (1.2) is included in the rectifier. - Page 12 Bridge rectification: Bridge rectifiers provide voltage with minimum residual ripple. This allows brake humming to be avoided even if small size brakes are used. In case of bridge rectification, the U coil voltage is lower by factor 0.89 than the rectifier input voltage.

Page 13: Microswitch (19) Connection
Attention! In case of DC side switching, the brake must be provided with a protective circuit to avoid overvoltage. Additional protective elements (e.g. varistors, spark arresters, etc.) must be installed to avoid damage such as burns or welded contacts. Warning! Work on the brake must only be carried out by suitably qualified personnel. - Page 14 Size tightening torque [Nm] of machine screws (20.1) for protective cover (20) tightening torque [Nm] of machine screws (19.5) for 0.75 0.75 0.75 0.75 microswitch cap (19.2) tightening torque [Nm] of machine screws (25.3) for connector box cover (25.1) Table 14/1: Tightening torques of machine screws for protective cover (20), microswitch cap (19.2) and connector box cover (25.1) Rectifier Microswitch S (19, NO contact)

Page 15: Electromagnetic Compatibility
3.4 Electromagnetic compatibility As required by the German Electromagnetic Compatibility Act (EMVG), electromagnetic compatibility is essential to ensure immunity to external electromagnetic fields and conducted interference. Furthermore, the emission of electromagnetic fields and line-conducted interference during brake operation must be minimised. Since the brake features depend on the circuitry and operation, a declaration of conformity with the applicable EMC standard can only be furnished for the wiring type, but not for a specific brake. - Page 16 EN 61000-4-11 Voltage dips, short interruptions, and short supply voltage variations: Voltage interruptions: Brakes that comply with the requirements of DIN VDE 0580 are de-energised after the specified switching times at the latest. The switching time depends on the control and mains conditions (e.g. generator effect of running down motors).
- Page 17 If the brake is used in connection with other electronic accessories, the user is responsible to ensure compliance with EMC requirements. Compliance with applicable standards concerning the design and operation of components, sub-assemblies or equipment employed shall not relieve the user and manufacturer of the overall system from their obligation to furnish proof of conformity of the overall system with such standards.

Page 18: Set-Up And Start-Up
3.5 Set-up and start-up Warning! The functional check of the brake must not be performed unless the machine (e.g. motor) has been switched off and secured against accidental or unintentional start-up. 3.5.1 Functional checks The following checks must be carried out: Check compliance with the specifications provided on the rating plate with respect to the mounting position and protection class. -
Page 19: Manual Brake Release
Attention! Check that the brake has been connected in accordance with the specifications provided on the rating plate before it is put into operation. Even short-term operation outside the specified supply voltage limits may cause irreversible damage to the brake or electronic accessories. Such damage may not be apparent immediately. DC side brake switching without protective circuit as described in Section 3.4 will cause damage to electronic rectifiers, electronic accessories, switching contacts and to the field coil (1.2). -
Page 20: Maintenance
4. Maintenance 4.1 Checks and service The spring-applied single-disc brake does not require any particular maintenance except that the air gap 's' must be measured at regular intervals. After the screw plugs (23) have been removed from the intermediate ring (6), the air gap 's' (see Table 29/1 for rated air gap specification) between the armature (2) and the friction disc (5) can be checked by means of a feeler gauge while the brake is energised. -
Page 21: Microswitch (19) Adjustment (Only Applicable To Brakes With Microswitch (19))
4.2 Microswitch (19) adjustment (only applicable to brakes with microswitch (19)) The spring-applied single-disc brake must be released electrically to allow the microswitch (19) to be adjusted. Unscrew the locknut (19.3) and turn the hexagon head cap screw (19.4) clockwise until the microswitch (19) switches (slight audible click or contact closure between the NO and C contacts). -

Page 23: Heat
6.2 Heat Braking operations and gradual heating of the field coil cause the solenoid housing temperature to increase substantially. Under adverse conditions, the surface temperature may rise to well over 60°C. Caution! Risk of burns in case of contact with hot surfaces! Suitable covers and hand guards must be installed to provide protection against accidental contact. -
Page 24: Safety
Retrofitting or modification work to be carried out on the brake is subject to the approval from Kendrion (Villingen). Accident prevention regulations applying to the specific field of application of the brake must be strictly observed. The brakes described in this manual are not designed for use as "safety brakes". -
Page 25: Set-Up
8.2.1 Set-up Requirements in terms of the permitted number of switching operations per hour and the maximum switching work per switching operation specified in the technical specifications must be strictly observed during the set- up of machines and plant (inching mode). Failure to observe these instructions may irreversibly diminish the braking effect and cause malfunctions. -
Page 26: Maintenance, Repair And Replacement
Notice! During brake operation, ensure that the coil temperature does not rise above the permissible limit temperature applicable to the insulating materials of the specified insulation class (see Table 29/1 “Technical specifications”). Fast cooling of the field coil with scavenging air is not allowed. Ensure that the permissible relative humidity range (see Table 31/1) is not exceeded. -
