27、g safety information must be observed:Shutdown equipment prior to fitting brakeBefore fitting the brake, it must be ensured that the equipment to which the brake is to be fitted is shutdown andsecured to prevent accidental activation.Do not use any greaseThe brake is designed for dry-running operati

28、on. For this reason, no greases or oils must be used during installation of the brake. Greases and oils reduce the braking action. The hub in particular must not be oiled or greased.Danger of crushingWhen carrying out work on the brake, heavy tools are used. Particular attention should therefore be

29、paid to possible crushing points when:Using tools Fitting and removing the brake, accessories or spare partsUnbolting the brake from the palletUse lifting equipmentThe brake can weigh between 19 and 750 kg depending on type. For brake installation purposes, lifting gear or another crane can be used.

30、Do not use a crane that is being fitted with brakesUnder no circumstances should the crane to which brakes are being fitted be used for lifting purposes.Protection of inner brakeDirt, oil and spray water reduce the braking capacity. Friction linings, brake flange and armature plate must be protected

31、 when the brake is open.InstallationFittingAlignment during fitting depends on the position of the motor or gear shaft. The brake must be prepared for fitting according to the following procedure:-Remove cap nuts and sealing rings-Remove housing-Simultaneously tighten manual release bolts evenly clo

32、ckwise, so that the friction lining group moves freely Manual release boltsArmature plateAirgapCoil body groupFriction lining group-Check that the lining group moves freelyIf the friction lining group does not move freely:-Simultaneously further tighten manual release bolts carefully and evenly cloc

33、kwisePrior to fitting the brake:- KeyMotor shaftHub-Secure the hub axially with the shaft and washer or circlip.Installation With suitable lifting gear, lift the brake so that the adapter flange and brake can be cleaned and sealing compound applied, e.g. Curil K2.-Subsequently clean the motor flange

34、 and apply sealing compound.-Lift the brake with suitable lifting gear and carefully position the teeth of the friction lining group over the teeth of the driving hub.-Feed the connecting cable through the opening in the adapter flange as shown as illustrated.-Have electrical connections made by a q

35、ualified electrician.Also observe the safety information in the chapter “Electrical connection”. Array-After electrical connection, bolt the brake adapter flange to the motor flange.Observe bolt tightening torque.The prescribed tightening torque must be observed when tightening bolts (see “Technical

36、 Data”.-Simultaneously unscrew both manual release bolts evenly counter-clockwise until the bolt heads just make contact with the brake flange.Do not unscrew manual release bolts with forceIf the manual release bolts are unscrewed with force over and beyond the resistance, the brake can be damaged.E

37、nsuring correct braking actionA check should be made to ensure that the manual release bolts are unscrewed properly. If the manual release bolts are tightened, the brake will not operate or be restricted.Remove foreign bodies on O-ring and contact surfaces.When fitting the housing, the housing O-rin

38、g and contact surfaces must be from foreign bodies,otherwise the housing will not provide a proper seal.-Clean O-ring and contact surface.- Fit the housing noting the installation position, the mark on the housing must correspond with themark on the adapter flange. Electrical connectionDuring instal

39、lation, electrical connection of the brake must be established. Only qualified electricianOnly a qualified electrician may connect the brake to the DC supply and check the current flow, taking into all safety measures. Incorrect connection may have fatal consequences! EarthingThe brake must be earth

40、ed in compliance with the applicable regulations. Disconnect system from the supplyThe supply must be disconnected before carrying out any work on the electrical system. Provide overvoltage protectionBrakes with a coil output of 100 W and higher must be provided with overvoltage protection to preven

41、t damage to the coil on disconnection of the brake power supply. Prevent brake overheatingTo prevent the brake overheating, it must be ensured that the motor to be braked does not continue to run in the event of an undesired power failure. Do not switch onDisconnect the power supply to the motor bef

42、ore connecting the brake. -Establish electrical connection.- Remove the sign.Marks(notchesBrake adapter flangeHousingCommissioningPrior to commissioning the brake, the following safety information must be observed:Overloading the brakeThe operator is obliged to adjust the motor for the brake in such

43、 a way that the brake cannot be overloaded. Overloading the brake would cause heavy brake lining wear.Note: As a result of chemical degreasing at the factory, the armature plate and brake flange may have a bluish discoloration; this is not an indication of thermal overload.Risk of burns! During oper

44、ation, the brake can reach temperatures up to 80C. Any contact with the hotbrake housing must therefore be avoided.Maintain maximum speed rangeIn order to prevent damage to the brake, the brake must be operated also during commissioning only within the permissible speed range.Note: Loading case and

45、technical data sheets must be observed.Function checkA function check must be carried out prior to each initial use. Observe the safety information beforecarrying out the function check:Do not place or leaving anything lying around in this area Remove all metal or flammable objects from the working

46、area of the brake.Do not reach into rotating brakeIf the function check is carried out with the housing removed, reaching into rotating brake must be avoided in any event.Seal replacementAll seals removed for the function check must be replaced with new seals.CommissioningFunction check- With the ho

47、using removed, connect and disconnect the brake power supply several timesThe armature plate moves during switching between the coil body group and friction lining group. After completing function check:- The procedure for cleaning and fitting the housing is as described in the chapter “Installation

48、” under the section “Fitting the brake”.Checking the airgapTo ensure correct operation of the brake, the airgap between the coil body group and armature plate must have the prescribed size. The minimum or maximum airgap is shown on the brake rating plate. The brake is set with the minimum airgap at

49、the factory.Check the airgap through the open tapped holes at three points:Bolt with sealing ring -Unscrew bolts with sealing rings from the housing -Insert feeler gauge through the open tapped holes at all three points -Measure the airgap between the armature plate and coil body group.- Re-insert b

50、olts with sealing rings and tighten. Old sealing rings cannot prevent the ingress of water.Mode of operation of the brakeConnection of the brake power supplyOn connection of the brake power supply, an electromagnetic field builds up. This causes the armature plate to be drawn towards the coil body g

51、roup and the brake is released. The friction lining group of the brake can now rotate freely between the armature plate and brake flange.Disconnection of the brake power supplyOn disconnection of the brake power supply, the electromagnetic field collapses and the brake is applied.The pressure of the

52、 springs forces the armature plate against the friction lining group. The friction lining group simultaneously presses against the brake flange.The mechanical friction is transferred to the motor shaft via the friction lining plate and driving hub. The motor is braked.Running-in friction liningsWith

53、 the commissioning of the brake or after renewal of the friction lining group, the friction linings must be run-in. Only when this has been done is the specified braking torque fully transmitted.Several controlled braking operations should be carried out, bearing in mind that the full braking power

54、is not initially available. Braking under full load must be avoided.OperationThe following safety information must be observed for operation of the brake: Usual changesIn the event of any unusual changes to the brake, the brake power supply must immediately bedisconnected. Any unusual changes , e.g.

55、 the development of smell at the brake, should immediately be reported to the person concerned or the customer service department notified in order to prevent the brake suffering further damage. Permissible braking energyThe permissible braking energy can be determined from the thermal load diagram.

56、 With a known switching energy per braking operation and number of braking operations per hour, the brake size can be determined. Example: Q = 100 kJ/switching energy and z = 35 braking operations/hour = brake SFB 100.Braking speed n = 1500 rpmBraking operation per hour z1/hManual releaseReleasing t

57、he brake manually means briefly releasing the brake by manual actions and only in an emergency, e.g. in order to lower suspended loads carefully.The following safety information must be observed before releasing the brake manually: Manual release only for emergenciesUnder no circumstances must the manual release be used for the purpose of maintaining temporary operation. It is intended for emergency use only.It must be ensured when releasing the brake man
