  • Page 7: 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 utilized to overcome the braking effect produced by the spring force. The spring-applied single-disc brake engages in unpowered condition and releases when AC voltage is applied. The form-fit connection between the friction disc and hub and the connection of the hub with the machine shaft (e.g.

  • Page 10: Installation

    3. Installation 3.1 Mechanical installation Slip the hub (17) of the spring-applied single-disc brake on a shaft (tolerance h6) provided with a feather key to DIN 6885, sheet 1. As the hub (17) is firmly fitted to the brake, it need not be axially secured on the machine shaft (e.g. motor shaft).
  • Page 11: Installation Of The Hand Release (29) (Brake Types With Hand Release)

    3.2 Installation of the hand release (29) (brake types with hand release) Insert the hand release handle (29) into the square socket of the two cams (29.1) that are firmly fitted to the circumference of the solenoid housing (1.1). Ensure that the handle is correctly positioned. The mechanical release forces F and the maximum permissible release forces (actuation forces) F are specified in Table 11/1.

    Attention! To avoid damage (e.g. burns or fusing of contacts) to the external circuitry in case of DC side brake switching, additional protection elements (e.g. varistors, spark arresters, etc.) are necessary. Warning! Work on the brake must only be carried out by suitably qualified personnel. Make sure that no voltage is applied during brake connection.

    Warning! Any adjustment of the rated torque must be performed by the manufacturer or by authorized specialist personnel. 4. Maintenance 4.1 Checks and service The spring-applied single-disc brake does not require any particular maintenance except that the friction disc (5) must be replaced when worn (see “Technical specifications” for information on the maximum air gap s and that the safety switches (microswitch (13) and thermoswitches (11 &...

  • Page 21 Microswitch (13) adjustment or replacement (relevant only for brake types equipped with microswitch): The spring-applied single-disc brake must be released electrically before the microswitch (13) can be adjusted. Loosen the socket head cap screws (20) provided on the cover (7) and remove the cover (7). Unscrew the locknut (13.1) and turn the set screw (13.2) clockwise until the microswitch (13) switches (slight audible click or contact closure between contacts 5 and 6 (see Section 3.3).

    8.2.1 Set-up Requirements in terms of the permissible number of switching operations per hour and the maximum switching work per switching operation (see Fig. 32/1) specified in the technical specifications must be strictly observed during the set-up of machines and plant (jog mode). Failure to observe these instructions may irreversibly diminish the braking effect and cause malfunctions.

    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 30/1). Fast cooling of the field coil with scavenging air is not allowed. Ensure that the permissible relative humidity range (see Table 31/2) is not exceeded.
