Symbol designating an action that might damage the brake 2 Precautions and restrictions on use 2.1 Restrictions on use Symbol designating an action that might be dangerous to human safety For the brake to comply with directive 95/16/ EC, the integrator must observe the general conditions for installation, as stated in the EC type-examination certificate ref. ABV775/1 of 03/05/2010 from TÜV SÜD Industrie Service. These brakes are designed to work in dry conditions. Any contact with oil, grease, water or abrasive dust causes a decrease in torque. Warning : It is the responsibility of the customer to install the necessary protection to prevent pollution of the friction surfaces and to ensure that these same friction surfaces are thoroughly degreased and clean before mounting the brake. Torque subject to decrease in case of water contamination. Warning : brake must be replaced after water contamination. This product is not suitable for use according to ATEX/94/9/EC. These units are designed for use in an ambiant temperature between 0 C and 40 C maximum. Warning : at low temperature, any freezing of the friction face, due to condensation, generates a loss of torque. It is the responsability of the customer to take measures to avoid this problem. It is mandatory to follow instructions and datas given in documentation and marking of the units, in order to ensure the performance of the brake. This brake may only be used in a “horizontal axis”. The customer must be careful not to alter the factory-set airgap and the working clearance of the brake and the hand lever. Protection class: Mechanical : IP10 Electrical : IP54 Insulation class: F 155 C This brake is designed for static applications. Any dynamic braking is restricted to emergency braking and test braking. This brake can in no way replace the safety braking system used during lift descent. Nominal torque is reached by burnishing of brake in customer plant. Recommended: permanent sliding 11 RPM during 300 s. If maximum rotation speeds are exceeded, the guarantee is no longer valid. When switching on DC-side the coil must be protected against voltage transients. 2.2 Symbol designating an electrical action that might be dangerous to human safety Precautions and safety measures During maintenance, make sure that the mechanism to be braked by the brake, is stopped and that there is no risk of it accidentally starting up. All intervention have to be made by qualified personnel, owning this manual. Any modification made to the brake without the express authorisation of a representative of Warner Electric, in the same way than any use out of the contractual specifications accepted by "Warner Electric", will result in the warranty being invalidated and Warner Electric will no longer be liable in any way with regard to conformity. 3 Installation 3.1 Transport / storage These devices are delivered in a package guaranteeing the preservation of the product providing it is by surface transportation. In case of a specific request (air or sea transport, long-term storage, etc) contact our factory. 3.2 Handling 3.3 Avoid any impact to the brake so that its performance is not impaired. Never lift the brake by its cables Installation mounting In case of long storage, check the brakes, before setting the drives, in order to avoid, in case of large temperature variation, any risk of sticking from the friction material, able to hindrance the start of the drive. Data for customer friction disc: Material: steel (150 to 250 HV) or cast iron, thickness of the friction disc: 15 mm 0/-0,1, roughness of the friction faces: Ra 1,6. Protection: dry phosphatizing or Nitriding. Geometric tolerances: 0,1 0,1 Friction face / Pulley axis WARNER ELECTRIC EUROPE - Rue Champfleur, B.P. 20095, F - 49182 St Barthélemy d’Anjou Cedex SM429gb - rev 06/11 3/7

Data for mounting pins: Material: steel (min. 900 N/mm2), diameter 25h8, roughness: Ra 0.8. Protection: dry phosphatizing or Nitriding 0,1 Engage the brake, armature attracted under voltage or with hand release, on his disc. Mount the mounting pins, then the connecting bar and tighten with the indicated torque for the locknuts. Support axis / Pulley axis 3.3.1 Hand lever configuration 4 Maintenance According to the hand lever side of actuation, the customer must fit the pins, for limitation of the hand lever travel, in the selected position. Dimension of the pin out of the magnet: 6 max. (see Fig. 7). 4.1 Release right Adjusting the airgap Check the airgap at each maintenance inspection. Reminder: This brake is intended for a static application as a safety brake. Any dynamic braking is restricted to emergency and test braking. Normal use will not lead to any noticeable wear on the lining. The airgap adjustment must be reset before the max. airgap is reached. This to eliminate any functional problems because of the hand release travel. Slide two feeler gauges 0,3 mm thick in the airgap, Fig. 3a Release left avoiding the dampers, between the armature and the magnet (Fig. 5). Energize magnet.

Checking airgap area, see Fig. 6. Microswitch connection : According to versions, the brake is supplied either with a male connector, or with free wires of 1500 mm length (see chapter 5.3). Checking airgap area Normally closed (Connector version) Normally closed or normally opened, with the choice. (free wires version) Black 4.3 Red "NC" Blue "NO" Brake exchange All works on the electrical connections have to be made with power off. During maintenance, make sure that the mechanism to be braked by the brake, is stopped and that there is no risk of it accidentally starting up. All intervention have to be made by qualified personnel, owning this manual. Fig. 6 4.2 Adjusting the microswitch Slide a wedge 0,10 mm thick close to the screw between the face of the magnet and the moving armature. Switch on the current and tighten the adjusting screw H M5 (8/flat) in contact with the microswitch until you reach the commutation point. Check that it functions correctly by a few successive draws and releases (see Fig. 7). Fit again a 0,10 mm thick gauge and check if the adjustment is stable. Fit a 0,15 mm thick gauge and check that the microswitch is not actuated. Detection screw Detection screw, stroke measure Microswitch Airgap Pin: 6 max. see 3.3.1 Nut Disconnect the electrical connection, of the brake. Remove the brake. Clean the friction surfaces with a clean dry doth. These brakes are designed to work in dry conditions. Any contact with oil, grease, water or abrasive dust causes a decrease in torque. Mount the new brake, following the instructions in chapter 3.3. Warning: after replacement, it is necessary to make a dynamic braking test, in order to validate the installation. Fig. 7 Operation microswitch Current range 10 mA min. to 100 mA max. at 24 VDC Maximum electrical lifetime of the microswitch ensure only by switching under resistive load.
